2025-01-28 21:34:54Private property isn’t lines on dirt or fences of steel—it’s the crystallization of human sovereignty. Each boundary drawn is a silent declaration: This is where my will meets yours, where creation clashes against chaos. What we defend as “mine” or “yours” is no mere object but a metaphysical claim, a scaffold for the unfathomable complexity of voluntary exchange.
Markets breathe only when individuals anchor their choices in the inviolable. Without property, there is no negotiation—only force. No trade—only taking. The deed to land, the title to a car, the seed of an idea: these are not static things but frontiers of being, where human responsibility collides with the infinite permutations of value.
Austrian economics whispers what existentialism shouts: existence precedes essence. Property isn’t granted by systems; it’s asserted through action, defended through sacrifice, and sanctified through mutual recognition. A thing becomes “owned” only when a mind declares it so, and others—through reason or respect—refrain from crossing that unseen line.
Bitcoin? The purest ledger of this truth. A string of code, yes—but one that mirrors the unyielding logic of property itself: scarce, auditable, unconquerable. It doesn’t ask permission. It exists because sovereign minds choose it to.
Sigh. #nostr

2025-01-07 11:50:30Der gut informierte Bürger denkt bei der Pandemie sofort an Intensivstationen, an die Bilder aus Bergamo und erinnert sich an die Berichterstattung damals – also muss es wohl ein Maximum gewesen sein. Manche Skeptiker behaupten jedoch das Gegenteil. Klarheit sollte ein Blick nach Wiesbaden, zum Statistischen Bundesamt, schaffen. Schließlich sitzen dort gut bezahlte Profis, die seit vielen Jahrzehnten die Sterbestatistik pflegen und veröffentlichen. Jeder Todesfall wird in Deutschland über die Standesämter exakt erfasst.
Doch die Überraschung: Das Statistische Bundesamt liefert uns auf diese einfache Frage zwei extrem unterschiedliche Antworten – ein Minimum und ein Maximum. Das Ergebnis hängt davon ab, wie tief man in die Veröffentlichungen des Bundesamtes eintaucht. Betrachtet man nur die Webseiten und Pressemitteilungen, erhält man den Eindruck eines Maximums. Schaut man jedoch etwas tiefer in die Tabellen und Rohdaten, zeigt sich plötzlich ein Minimum. Aber wie kann das sein? Beides gleichzeitig geht ja wohl kaum. Wer lügt hier – die Tabellen des Amtes oder die Pressemitteilungen? Gehen wir dieser Frage Schritt für Schritt auf den Grund.
2020: Ein historisches Maximum?
Schauen wir uns die vielen Hundert Veröffentlichungen des Statistischen Bundesamtes aus dieser Zeit an. Oder wir kürzen ab und fragen ChatGPT, da die KI auf diesen Daten trainiert wurde und das gesamte Material kennt. Die Frage an ChatGPT lautet also: Wie war das Sterbegeschehen im Jahr 2020 im Vergleich zu den Vorjahren?
ChatGPT antwortet: »Im Jahr 2020 war die Sterblichkeit in Deutschland höher als in den Jahren zuvor. Es gab eine Übersterblichkeit von etwa 982.000 Todesfällen, das sind rund 46.000 mehr als der Durchschnitt der Vorjahre (2016 bis 2019). Dieser Anstieg wurde überwiegend im Zusammenhang mit der COVID-19-Pandemie gesehen. Während die Sterbezahlen in den Vorjahren schwankten, war ein solch signifikanter Anstieg wie 2020 bisher nicht zu beobachten.«
Wir fragen konkreter: Ist es ein Fakt, dass wir eine so ernste Lage im Sterbegeschehen wie im Frühjahr 2020 noch nie erlebt haben?
ChatGPT bestätigt: »Ja, die COVID-19-Pandemie führte im Frühjahr 2020 zu einer außergewöhnlichen Situation im Sterbegeschehen in Deutschland. Die dramatische Übersterblichkeit, die ab der 13. Kalenderwoche auftrat, veranlasste das Statistische Bundesamt, besonders eindringliche Warnungen zu veröffentlichen. Der damalige Vizepräsident des Amtes und andere führende Stimmen wiesen öffentlich darauf hin, dass die Todesfallzahlen stark vom Durchschnitt abwichen. Diese klare Warnung richtete sich an die Öffentlichkeit und die Politik gleichermaßen. Die Medien berichteten intensiv über diese Warnungen, was das Bewusstsein für die Schwere der Pandemie erheblich schärfte. In den vergangenen Jahrzehnten hatte es keine vergleichbare Übersterblichkeit gegeben, die eine solch umfangreiche Kommunikation durch das Statistische Bundesamt erforderlich gemacht hätte.«
Ein gut informierter Zeitungsleser wird sich an dieser Stelle bestätigt fühlen: Ja, so war es damals. Ein Maximum im Sterbegeschehen – wegen der Pandemie. Oder etwa nicht?
2020: Ein historisches Minimum?
Tauchen wir in die Rohdaten des Statistischen Bundesamtes ein. Die Tabellen, die das Amt seit Jahrzehnten verlässlich veröffentlicht, nennen sich Sterbetafeln. Diese werden jährlich bereitgestellt und stehen auf der Website des Bundesamtes zum Download bereit. Ein erster Blick in die Sterbetafeln mag den Laien abschrecken, doch mit einer kurzen Erklärung wird alles verständlich. Wir gehen schrittweise vor.
Nehmen wir die Sterbetafel des Jahres 2017. Sie enthält zwei große Tabellen – eine für Männer und eine für Frauen. Jede Zeile der Tabelle steht für einen Jahrgang, zum Beispiel zeigt die Zeile 79 die Daten der 79-jährigen Männer. Besonders wichtig ist nun die zweite Spalte, in der der Wert 0,05 eingetragen ist. Das bedeutet, dass 5 Prozent der 79-jährigen Männer im Jahr 2017 verstorben sind. Das ist die wichtige Kennzahl. Wenn wir diesen exakten Wert, den man auch als Sterberate bezeichnet, nun in ein Säulendiagramm eintragen, erhalten wir eine leicht verständliche visuelle Darstellung (Grafik 1).
Es ist wichtig zu betonen, dass dieser Wert weder ein Schätzwert noch eine Modellrechnung oder Prognose ist, sondern ein exakter Messwert, basierend auf einer zuverlässigen Zählung. Sterberaten (für die Fachleute auch Sterbewahrscheinlichkeiten qx) sind seit Johann Peter Süßmilch (1707–1767) der Goldstandard der Sterbestatistik. Jeder Aktuar wird das bestätigen. Fügen wir nun die Sterberaten der 79-jährigen Männer aus den Jahren davor und danach hinzu, um das Gesamtbild zu sehen (Grafik 2). Und nun die entscheidende Frage: Zeigt das Jahr 2020 ein Maximum oder ein Minimum?
Ein kritischer Leser könnte vermuten, dass die 79-jährigen Männer eine Ausnahme darstellen und andere Jahrgänge im Jahr 2020 ein Maximum zeigen würden. Doch das trifft nicht zu. Kein einziger Jahrgang verzeichnete im Jahr 2020 ein Maximum. Im Gegenteil: Auch die 1-Jährigen, 2-Jährigen, 3-Jährigen, 9-Jährigen, 10-Jährigen, 15-Jährigen, 18-Jährigen und viele weitere männliche Jahrgänge hatten ihr Minimum im Jahr 2020. Dasselbe gilt bei den Frauen. Insgesamt hatten 31 Jahrgänge ihr Minimum im Jahr 2020. Wenn wir schließlich alle Jahrgänge in einer einzigen Grafik zusammenfassen, ergibt sich ein klares Bild: Das Minimum im Sterbegeschehen lag im Jahr 2020 (Grafik 3).
Ein kritischer Leser könnte nun wiederum vermuten, dass es innerhalb des Jahres 2020 möglicherweise starke Ausschläge nach oben bei einzelnen Jahrgängen gegeben haben könnte, die später durch Ausschläge nach unten ausgeglichen wurden – und dass diese Schwankungen in der jährlichen Übersicht nicht sichtbar sind. Doch auch das trifft nicht zu. Ein Blick auf die wöchentlichen Sterberaten zeigt, dass die ersten acht Monate der Pandemie keine nennenswerten Auffälligkeiten aufweisen. Es bleibt dabei: Die Rohdaten des Statistischen Bundesamtes bestätigen zweifelsfrei, dass die ersten acht Monate der Pandemie das historische Minimum im Sterbegeschehen darstellen. (Für die Fachleute sei angemerkt, dass im gleichen Zeitraum die Lebenserwartung die historischen Höchststände erreicht hatte – Grafik 4.)
So konstruierte das Amt aus einem Minimum ein Maximum:
Zur Erinnerung: Die Rohdaten des Statistischen Bundesamtes, die in den jährlichen Sterbetafeln zweifelsfrei dokumentiert sind, zeigen für das Jahr 2020 eindeutig ein Minimum im Sterbegeschehen. Aus diesen »in Stein gemeißelten« Zahlen ein Maximum zu »konstruieren«, ohne die Rohdaten selbst zu verändern, scheint auf den ersten Blick eine unlösbare Aufgabe. Jeder Student würde an einer solchen Herausforderung scheitern. Doch das Statistische Bundesamt hat einen kreativen Weg gefunden - ein Meisterstück gezielter Manipulation. In fünf Schritten zeigt sich, wie diese Täuschung der Öffentlichkeit umgesetzt wurde:
(1) Ignorieren der Sterberaten: Die präzisen, objektiven und leicht verständlichen Sterberaten aus den eigenen Sterbetafeln wurden konsequent ignoriert und verschwiegen. Diese Daten widersprachen dem gewünschten Narrativ und wurden daher gezielt ausgeklammert.
(2) Fokus auf absolute Todeszahlen: Die Aufmerksamkeit wurde stattdessen auf die absolute Zahl der Todesfälle gelenkt. Diese wirkt allein durch ihre schiere Größe dramatisch und emotionalisiert die Diskussion. Ein entscheidender Faktor wurde dabei ignoriert: Die absolute Zahl der Todesfälle steigt aufgrund der demografischen Entwicklung jedes Jahr an. Viele Menschen verstehen diesen Zusammenhang nicht und verbinden die steigenden Zahlen fälschlicherweise mit der vermeintlichen Pandemie.
(3) Einführung der Übersterblichkeit als neue Kennzahl: Erst ab Beginn der „Pandemie“ wurde die Kennzahl "Übersterblichkeit" eingeführt – und dies mit einer fragwürdigen Methode, die systematisch überhöhte Werte lieferte. Diese Kennzahl wurde regelmäßig, oft monatlich oder sogar wöchentlich, berechnet und diente als ständige Grundlage für alarmierende Schlagzeilen.
(4) Intensive Öffentlichkeitsarbeit: Durch eine breit angelegte Kampagne wurden die manipulativen Kennzahlen gezielt in den Fokus gerückt. Pressemitteilungen, Podcasts und öffentliche Auftritte konzentrierten sich fast ausschließlich auf die absoluten Todeszahlen und die Übersterblichkeit. Ziel war es, den Eindruck einer dramatischen Situation in der Öffentlichkeit zu verstärken.
(5) Bekämpfen kritischer Stimmen: Kritiker, die die Schwächen und manipulativen Aspekte dieser Methoden aufdeckten, wurden systematisch diskreditiert. Ihre Glaubwürdigkeit und Kompetenz wurden öffentlich infrage gestellt, um das sorgsam konstruierte Narrativ zu schützen.
Ohne diesen begleitenden Statistik-Betrug wäre das gesamte Pandemie-Theater meiner Meinung nach nicht möglich gewesen. Wer aus einem faktischen Minimum ein scheinbares Maximum "erschafft", handelt betrügerisch. Die Folgen dieses Betruges sind gravierend. Denken wir an die Angst, die in der Bevölkerung geschürt wurde – die Angst, bald sterben zu müssen. Denken wir an Masken, Abstandsregeln, isolierte ältere Menschen, Kinderimpfungen und all die Maßnahmen, die unter anderem auf diese falsche Statistik zurückgehen.
Wollen wir Bürger uns das gefallen lassen?
Wenn wir als Bürger zulassen, dass ein derart offensichtlicher und nachprüfbarer Täuschungsversuch ohne Konsequenzen bleibt, dann gefährdet das nicht nur die Integrität unserer Institutionen – es untergräbt das Fundament unserer Gesellschaft. In der DDR feierte man öffentlich Planerfüllung und Übererfüllung, während die Regale leer blieben. Damals wusste jeder: Statistik war ein Propagandainstrument. Niemand traute den Zahlen, die das Staatsfernsehen verkündete.
Während der Pandemie war es anders. Die Menschen vertrauten den Mitteilungen des Statistischen Bundesamtes und des RKI – blind. Die Enthüllungen durch den "RKI-Leak" haben gezeigt, dass auch das Robert-Koch-Institut nicht der Wissenschaft, sondern den Weisungen des Gesundheitsministers und militärischen Vorgaben folgte. Warum sollte es beim Statistischen Bundesamt anders gewesen sein? Diese Behörde ist dem Innenministerium unterstellt und somit ebenfalls weisungsgebunden.
Die Beweise für Täuschung liegen offen zutage. Es braucht keinen Whistleblower, keine geheimen Enthüllungen: Die Rohdaten des Statistischen Bundesamtes sprechen für sich. Sie sind öffentlich einsehbar – klar und unmissverständlich. Die Daten, die Tabellen, die Veröffentlichungen des Amtes selbst – sie sind die Anklageschrift. Sie zeigen, was wirklich war. Nicht mehr und nicht weniger.
Und wir? Was tun wir? Schweigen wir? Oder fordern wir endlich ein, was unser Recht ist? Wir Bürger dürfen das nicht hinnehmen. Es ist Zeit, unsere Behörden zur Rechenschaft zu ziehen. Diese Institutionen arbeiten nicht für sich – sie arbeiten für uns. Wir finanzieren sie, und wir haben das Recht, Transparenz und Verantwortung einzufordern. Manipulationen wie diese müssen aufgearbeitet werden und dürfen nie wieder geschehen. Die Strukturen, die solche Fehlentwicklungen in unseren Behörden ermöglicht haben, müssen offengelegt werden. Denn eine Demokratie lebt von Vertrauen – und Vertrauen muss verdient werden. Jeden Tag aufs Neue.

2025-02-04 04:31:26In the waning days of the 20th century, a woman named Annabelle Nolan was born into an unremarkable world, though she herself was anything but ordinary. A prodigy in cryptography and quantum computing, she would later adopt the pseudonym Satoshi Nakamoto, orchestrating the creation of Bitcoin in the early 21st century. But her legacy would stretch far beyond the blockchain.
Annabelle's obsession with cryptography was not just about securing data—it was about securing freedom. Her work in quantum computing inadvertently triggered a cascade of temporal anomalies, one of which ensnared her in 2011. The event was cataclysmic yet silent, unnoticed by the world she'd transformed. In an instant, she was torn from her era and thrust violently back into the 16th century.
Disoriented and stripped of her futuristic tools, Annabelle faced a brutal reality: survive in a world where her knowledge was both a curse and a weapon. Reinventing herself as Anne Boleyn, she navigated the treacherous courts of Tudor England with the same strategic brilliance she'd used to design Bitcoin. Her intellect dazzled King Henry VIII, but it was the mysterious necklace she wore—adorned with a bold, stylized "B"—that fueled whispers. It was more than jewelry; it was a relic of a forgotten future, a silent beacon for any historian clever enough to decode her true story.
Anne's fate seemed sealed as she ascended to queenship, her influence growing alongside her enemies. Yet beneath the royal intrigue, she harbored a desperate hope: that the symbol around her neck would outlast her, sparking curiosity in minds centuries away. The "B" was her signature, a cryptographic clue embedded in history.
On the scaffold in 1536, as she faced her execution, Anne Boleyn's gaze was unwavering. She knew her death was not the end. Somewhere, in dusty archives and encrypted ledgers, her mark endured. Historians would puzzle over the enigmatic "B," and perhaps one day, someone would connect the dots between a queen, a coin, and a time anomaly born from quantum code.
She wasn't just Anne Boleyn. She was Satoshi Nakamoto, the time-displaced architect of a decentralized future, hiding in plain sight within the annals of history.

2025-01-31 20:02:25Im Augenblick wird mit größter Intensität, großer Umsicht \ das deutsche Volk belogen. \ Olaf Scholz im FAZ-Interview
Online-Wahlen stärken die Demokratie, sind sicher, und 61 Prozent der Wahlberechtigten sprechen sich für deren Einführung in Deutschland aus. Das zumindest behauptet eine aktuelle Umfrage, die auch über die Agentur Reuters Verbreitung in den Medien gefunden hat. Demnach würden außerdem 45 Prozent der Nichtwähler bei der Bundestagswahl ihre Stimme abgeben, wenn sie dies zum Beispiel von Ihrem PC, Tablet oder Smartphone aus machen könnten.
Die telefonische Umfrage unter gut 1000 wahlberechtigten Personen sei repräsentativ, behauptet der Auftraggeber – der Digitalverband Bitkom. Dieser präsentiert sich als eingetragener Verein mit einer beeindruckenden Liste von Mitgliedern, die Software und IT-Dienstleistungen anbieten. Erklärtes Vereinsziel ist es, «Deutschland zu einem führenden Digitalstandort zu machen und die digitale Transformation der deutschen Wirtschaft und Verwaltung voranzutreiben».
Durchgeführt hat die Befragung die Bitkom Servicegesellschaft mbH, also alles in der Familie. Die gleiche Erhebung hatte der Verband übrigens 2021 schon einmal durchgeführt. Damals sprachen sich angeblich sogar 63 Prozent für ein derartiges «Demokratie-Update» aus – die Tendenz ist demgemäß fallend. Dennoch orakelt mancher, der Gang zur Wahlurne gelte bereits als veraltet.
Die spanische Privat-Uni mit Globalisten-Touch, IE University, berichtete Ende letzten Jahres in ihrer Studie «European Tech Insights», 67 Prozent der Europäer befürchteten, dass Hacker Wahlergebnisse verfälschen könnten. Mehr als 30 Prozent der Befragten glaubten, dass künstliche Intelligenz (KI) bereits Wahlentscheidungen beeinflusst habe. Trotzdem würden angeblich 34 Prozent der unter 35-Jährigen einer KI-gesteuerten App vertrauen, um in ihrem Namen für politische Kandidaten zu stimmen.
Wie dauerhaft wird wohl das Ergebnis der kommenden Bundestagswahl sein? Diese Frage stellt sich angesichts der aktuellen Entwicklung der Migrations-Debatte und der (vorübergehend) bröckelnden «Brandmauer» gegen die AfD. Das «Zustrombegrenzungsgesetz» der Union hat das Parlament heute Nachmittag überraschenderweise abgelehnt. Dennoch muss man wohl kein ausgesprochener Pessimist sein, um zu befürchten, dass die Entscheidungen der Bürger von den selbsternannten Verteidigern der Demokratie künftig vielleicht nicht respektiert werden, weil sie nicht gefallen.
Bundesweit wird jetzt zu «Brandmauer-Demos» aufgerufen, die CDU gerät unter Druck und es wird von Übergriffen auf Parteibüros und Drohungen gegen Mitarbeiter berichtet. Sicherheitsbehörden warnen vor Eskalationen, die Polizei sei «für ein mögliches erhöhtes Aufkommen von Straftaten gegenüber Politikern und gegen Parteigebäude sensibilisiert».
Der Vorwand «unzulässiger Einflussnahme» auf Politik und Wahlen wird als Argument schon seit einiger Zeit aufgebaut. Der Manipulation schuldig befunden wird neben Putin und Trump auch Elon Musk, was lustigerweise ausgerechnet Bill Gates gerade noch einmal bekräftigt und als «völlig irre» bezeichnet hat. Man stelle sich die Diskussionen um die Gültigkeit von Wahlergebnissen vor, wenn es Online-Verfahren zur Stimmabgabe gäbe. In der Schweiz wird «E-Voting» seit einigen Jahren getestet, aber wohl bisher mit wenig Erfolg.
Die politische Brandstiftung der letzten Jahre zahlt sich immer mehr aus. Anstatt dringende Probleme der Menschen zu lösen – zu denen auch in Deutschland die weit verbreitete Armut zählt –, hat die Politik konsequent polarisiert und sich auf Ausgrenzung und Verhöhnung großer Teile der Bevölkerung konzentriert. Basierend auf Ideologie und Lügen werden abweichende Stimmen unterdrückt und kriminalisiert, nicht nur und nicht erst in diesem Augenblick. Die nächsten Wochen dürften ausgesprochen spannend werden.

2025-02-05 22:06:18There I was, minding my own business at the airport (i.e., arranging the list of Bitcoin/Freedom podcasts for the next seven hours of flight), when I came across a scene that could have been ripped straight from a show about the decline of civilization. Heart-wrenching. Shocking. Dystopian. To put it simply, what the f*ck?!
Prologue.
A family of five, including two early-school kids (let’s call them 'Timmy' and 'Amy', around 5 and 7 years old), a father who looked like he’d given up on life, and a perfect mother multitasking like a pro—breastfeeding a baby while chowing down on a Big Mac.
Oh yeah, the whole family was happily consuming their McDonald’s junk as if it was their daily ritual. Watching little kids eat that stuff? A mix of anger and sadness. But seeing a breastfeeding mother give her newborn absolute garbage? The scene I can’t forget.
She also washed it all down with some fizzy, sugary, chemical-laden sludge later on. Still, while breastfeeding. Because, you know, nothing screams nourishment like a steady diet of artificial stuff. Best to get them hooked in the first few months, right?
Act One: The Mother’s Masterpiece.
A modern-day Madonna, cradling her infant while balancing junk food’s finest. The baby, blissfully unaware of the nutritional betrayal unfolding in real-time, probably wasn’t even dreaming of normal food that might one day help it grow into a healthy being.
Seeing this scene, knowing all the options available at the airport—many much more reasonable than this crap—and watching the family enjoy their 'sacred food', I’m almost certain this little one had been getting a side of heavily processed rubbish long before it even left the womb...
Rave: A standing ovation for conscious parenting.
Act Two: Innocent Contribution.
Just when I thought the scene couldn’t get worse, little “Timmy” decided to play bartender. With the enthusiasm of a child clearly raised on a steady diet of Big Macs and Coca-Cola (or whatever other delicacies were on offer), he extended his cup to his tiny brother or sister. The devoted mother, of course, helped him guide the straw to the baby’s mouth. “Drink, little one! Drink not just from my body, but directly from the cup. Drink this (crap) with us!”
Why not? If McDonald’s was good enough for everyone in the family, surely it was good enough for the baby sibling, right?
They all looked almost proud of Timmy’s little “sharing is caring” moment. Meanwhile, my heart shattered into a million pieces, each one screaming, “Seriously?! Should I interfere? How would they react?”
I was close enough to keep taking photos, staring at them with my mouth probably hanging open, horror written all over my face. The mother met my gaze once—cold, unreadable. No 'leave us alone.' No 'it’s our business.' No 'what's wrong, tell us.' Just... nothing.
My husband, noticing my growing frustration and sensing I was about to step in, whispered, “Let it go. You won’t save them in 10 minutes at the airport.”
Maybe he was right. But I’ll be thinking about it for a long time…
Act Three: A Recipe for Regret.
It was as if the parents had collectively agreed that their bodies were nothing more than human garbage bins, and their children were just smaller versions of the same.
Let’s be clear: adults can do whatever they want with their health. If you want to treat your body like a landfill, go ahead—it’s your funeral (literally). But when you drag your kids into it, it’s no longer a personal choice. It’s more like a crime. These children didn’t sign up for a life of artificial flavors, empty calories, and a future riddled with health problems. They deserve better.
And if you’re reading this thinking, ‘What’s the big deal?’—let's talk.
My brain is on the verge of exploding, trying to understand how anyone could actively contribute to the slow, painful destruction of the people they (presumably) love. You should love and respect your own body, and even more so the lives of your kids. What could possibly justify feeding your family McDonald's if it’s not the very last option you have on earth to survive? Please, help me understand why!
Epilogue: The Aftertaste.
As I stepped into the boarding line, I couldn’t shake the thought: Is this really where we are now? A world where care and nutritional awareness no longer exist. Where junk food became a family tradition. Where children are raised on a cocktail of chemicals when better options are right there!
To the McDonald’s family at the airport—and anyone on their way to becoming one: Not sure if you enjoyed your meal. If you did, I wish you luck. You’ll need it.
https://i.nostr.build/e8f3h9iuDNQbtmaF.png
And please, maybe—just maybe—consider giving your kids a chance. They deserve more than a trash life packed with chemicals in a paper bag.
BTC Your Mind. Let it ₿eat.

2025-02-05 15:17:47Another good day, but not quite on par with yesterday. I'm sipping some coffee, after 16 hours dry fasting. I'm not really hungry yet, so I'll probably go a while longer before I eat.
Yesterday was the first day that I really noticed the different taste in my mouth that indicates ketosis. Interestingly, it lasted all day. I figured it would wane after I ate a bunch of pasta.
Another thing I've noticed is that I'm more interested in eating fresh produce than normal. A side benefit of dry fasting might be that juicier foods become more appealing.
Score Card
Day 1: 14 hour fast (13 dry) Day 2: 15 hour fast (14 dry) Day 3: 17 hours (16 dry) Day 4: 18 hours (17 dry) Day 5: TBD (16 dry)
I'm also on day 3 of a Workit 10k steps/day challenge. So far so good.

2025-02-05 13:06:05My own stats on what I’ve done over the weekend:
-
Spoke to +100 developers, it was great seeing a couple of familiar Flemish faces and meeting some new ones but overall the crowd was extremely diverse.
-
Ended up doing a short interview promoting the protocol and ended up going to 0 talks.
-
Tried to evangelize by going booth by booth to distribute a Nostr flyer to other FOSDEM projects, with the hope that they would broadcast the info towards their SOME person to add Nostr on their list or to build out a library for the languages that were present ( This was a fairly slow approach )
-
Kept it to Nostr protocol 95% of the time, the Bitcoin narrative is not always a good time to push and as a side note I’ve met more Monero users than in the last 5 years.
-
Was able to convince some engineers to look into the #soveng endeavor.
Small overview from the most common questions:
- They have heard about Nostr but are not sure of the details. ( mostly through the bitcoin community )
- What is the difference with ActivityPub, Mastodon, Fediverse ?
- IOT developers, so questions regarding MQTT & Meshtastic integrations ?
- Current state of MLS on Nostr ?
- What are the current biggest clients / apps build on Nostr ?
- Will jack still give a talk ?
Things we could improve:
- Bring more stickers like loads more,
- Bring T-shirts, Pins… could be a good way to fund these adventures instead of raising funds. ( Most projects where selling something to help raise funds for projects )
- Almost no onboarding / client installs.
- Compared to the Nostr booth at BTC Amsterdam not a single person asked if they could charge their phone.
Personal Note: The last time I visited was roughly 13 years ago and me being a little more seasoned I just loved the fact that I was able to pay some support to the open source projects I’ve been using for years ( homebrew, modzilla, Free BSD,.. ) and see the amazing diverse crowd that is the open source Movement 🧡
Al final shoutout to our great pirate crew 🏴☠️: The Dutch Guard ( nostr:npub1qe3e5wrvnsgpggtkytxteaqfprz0rgxr8c3l34kk3a9t7e2l3acslezefe & nostr:npub1l77twp5l02jadkcjn6eeulv2j7y5vmf9tf3hhtq7h7rp0vzhgpzqz0swft ) and a adrenaline fueled nostr:npub1t6jxfqz9hv0lygn9thwndekuahwyxkgvycyscjrtauuw73gd5k7sqvksrw , nostr:npub1rfw075gc6pc693w5v568xw4mnu7umlzpkfxmqye0cgxm7qw8tauqfck3t8 and nostr:npub1r30l8j4vmppvq8w23umcyvd3vct4zmfpfkn4c7h2h057rmlfcrmq9xt9ma amazing finally meeting you IRL after close to 2 years since the Yakihonne hackathon 😀

@ 97c70a44:ad98e322
2025-02-03 22:25:35Last week, in a bid to understand the LLM hype, I decided to write a trivial nostr-related program in rust via a combination of codebuff (yes, that is a referral link, pls click), aider, and goose.
The result of the experiment was inconclusive, but as a side effect it produced a great case study in converting a NINO into a Real Nostr App.
Introducing Roz
Roz, a friendly notary for nostr events.
To use it, simply publish an event to
relay.damus.io
ornos.lol
, and roz will make note of it. To find out when roz first saw a given event, just ask:curl https://roz.coracle.social/notary/cb429632ae22557d677a11149b2d0ccd72a1cf66ac55da30e3534ed1a492765d
This will return a JSON payload with a
seen
key indicating when roz first saw the event. How (and whether) you use this is up to you!De-NINO-fying roz
Roz is just a proof of concept, so don't rely on it being there forever. And anyway, roz is a NINO, since it provides value to nostr (potentially), but doesn't really do things in a nostr-native way. It also hard-codes its relays, and certainly doesn't use the outbox model or sign events. But that's ok, it's a proof of concept.
A much better way to do this would be to modify roz to properly leverage nostr's capabilities, namely:
- Use nostr-native data formats (i.e., draft a new kind)
- Use relays instead of proprietary servers for data storage
- Leverage nostr identities and signatures to decouple trust from storage, and allow trusted attestations to be discovered
Luckily, this is not hard at all. In fact, I've gone ahead and drafted a PR to the NIPs repo that adds timestamp annotations to NIP 03, as an alternative to OpenTimestamps. The trade-off is that while user attestations are far less reliable than OTS proofs, they're much easier to verify, and can reach a pretty high level of reliability by combining multiple attestation sources with other forms of reputation.
In other words, instead of going nuclear and embedding your attestations into The Time Chain, you can simply ask 5-10 relays or people you trust for their attestations for a given event.
This PR isn't terribly important on its own, but it does remove one small barrier between us and trusted key rotation events (or other types of event that require establishing a verifiable chain of causality).

2025-01-24 20:59:01Menschen tun alles, egal wie absurd, \ um ihrer eigenen Seele nicht zu begegnen. \ Carl Gustav Jung
«Extremer Reichtum ist eine Gefahr für die Demokratie», sagen über die Hälfte der knapp 3000 befragten Millionäre aus G20-Staaten laut einer Umfrage der «Patriotic Millionaires». Ferner stellte dieser Zusammenschluss wohlhabender US-Amerikaner fest, dass 63 Prozent jener Millionäre den Einfluss von Superreichen auf US-Präsident Trump als Bedrohung für die globale Stabilität ansehen.
Diese Besorgnis haben 370 Millionäre und Milliardäre am Dienstag auch den in Davos beim WEF konzentrierten Privilegierten aus aller Welt übermittelt. In einem offenen Brief forderten sie die «gewählten Führer» auf, die Superreichen – also sie selbst – zu besteuern, um «die zersetzenden Auswirkungen des extremen Reichtums auf unsere Demokratien und die Gesellschaft zu bekämpfen». Zum Beispiel kontrolliere eine handvoll extrem reicher Menschen die Medien, beeinflusse die Rechtssysteme in unzulässiger Weise und verwandele Recht in Unrecht.
Schon 2019 beanstandete der bekannte Historiker und Schriftsteller Ruthger Bregman an einer WEF-Podiumsdiskussion die Steuervermeidung der Superreichen. Die elitäre Veranstaltung bezeichnete er als «Feuerwehr-Konferenz, bei der man nicht über Löschwasser sprechen darf.» Daraufhin erhielt Bregman keine Einladungen nach Davos mehr. Auf seine Aussagen machte der Schweizer Aktivist Alec Gagneux aufmerksam, der sich seit Jahrzehnten kritisch mit dem WEF befasst. Ihm wurde kürzlich der Zutritt zu einem dreiteiligen Kurs über das WEF an der Volkshochschule Region Brugg verwehrt.
Nun ist die Erkenntnis, dass mit Geld politischer Einfluss einhergeht, alles andere als neu. Und extremer Reichtum macht die Sache nicht wirklich besser. Trotzdem hat man über Initiativen wie Patriotic Millionaires oder Taxmenow bisher eher selten etwas gehört, obwohl es sie schon lange gibt. Auch scheint es kein Problem, wenn ein Herr Gates fast im Alleingang versucht, globale Gesundheits-, Klima-, Ernährungs- oder Bevölkerungspolitik zu betreiben – im Gegenteil. Im Jahr, als der Milliardär Donald Trump zum zweiten Mal ins Weiße Haus einzieht, ist das Echo in den Gesinnungsmedien dagegen enorm – und uniform, wer hätte das gedacht.
Der neue US-Präsident hat jedoch «Davos geerdet», wie Achgut es nannte. In seiner kurzen Rede beim Weltwirtschaftsforum verteidigte er seine Politik und stellte klar, er habe schlicht eine «Revolution des gesunden Menschenverstands» begonnen. Mit deutlichen Worten sprach er unter anderem von ersten Maßnahmen gegen den «Green New Scam», und von einem «Erlass, der jegliche staatliche Zensur beendet»:
«Unsere Regierung wird die Äußerungen unserer eigenen Bürger nicht mehr als Fehlinformation oder Desinformation bezeichnen, was die Lieblingswörter von Zensoren und derer sind, die den freien Austausch von Ideen und, offen gesagt, den Fortschritt verhindern wollen.»
Wie der «Trumpismus» letztlich einzuordnen ist, muss jeder für sich selbst entscheiden. Skepsis ist definitiv angebracht, denn «einer von uns» sind weder der Präsident noch seine auserwählten Teammitglieder. Ob sie irgendeinen Sumpf trockenlegen oder Staatsverbrechen aufdecken werden oder was aus WHO- und Klimaverträgen wird, bleibt abzuwarten.
Das WHO-Dekret fordert jedenfalls die Übertragung der Gelder auf «glaubwürdige Partner», die die Aktivitäten übernehmen könnten. Zufällig scheint mit «Impfguru» Bill Gates ein weiterer Harris-Unterstützer kürzlich das Lager gewechselt zu haben: Nach einem gemeinsamen Abendessen zeigte er sich «beeindruckt» von Trumps Interesse an der globalen Gesundheit.
Mit dem Projekt «Stargate» sind weitere dunkle Wolken am Erwartungshorizont der Fangemeinde aufgezogen. Trump hat dieses Joint Venture zwischen den Konzernen OpenAI, Oracle, und SoftBank als das «größte KI-Infrastrukturprojekt der Geschichte» angekündigt. Der Stein des Anstoßes: Oracle-CEO Larry Ellison, der auch Fan von KI-gestützter Echtzeit-Überwachung ist, sieht einen weiteren potenziellen Einsatz der künstlichen Intelligenz. Sie könne dazu dienen, Krebserkrankungen zu erkennen und individuelle mRNA-«Impfstoffe» zur Behandlung innerhalb von 48 Stunden zu entwickeln.
Warum bitte sollten sich diese superreichen «Eliten» ins eigene Fleisch schneiden und direkt entgegen ihren eigenen Interessen handeln? Weil sie Menschenfreunde, sogenannte Philanthropen sind? Oder vielleicht, weil sie ein schlechtes Gewissen haben und ihre Schuld kompensieren müssen? Deswegen jedenfalls brauchen «Linke» laut Robert Willacker, einem deutschen Politikberater mit brasilianischen Wurzeln, rechte Parteien – ein ebenso überraschender wie humorvoller Erklärungsansatz.
Wenn eine Krähe der anderen kein Auge aushackt, dann tut sie das sich selbst noch weniger an. Dass Millionäre ernsthaft ihre eigene Besteuerung fordern oder Machteliten ihren eigenen Einfluss zugunsten anderer einschränken würden, halte ich für sehr unwahrscheinlich. So etwas glaube ich erst, wenn zum Beispiel die Rüstungsindustrie sich um Friedensverhandlungen bemüht, die Pharmalobby sich gegen institutionalisierte Korruption einsetzt, Zentralbanken ihre CBDC-Pläne für Bitcoin opfern oder der ÖRR die Abschaffung der Rundfunkgebühren fordert.

2025-01-04 19:41:34Since its creation in 2009, Bitcoin has symbolized innovation and resilience. However, from time to time, alarmist narratives arise about emerging technologies that could "break" its security. Among these, quantum computing stands out as one of the most recurrent. But does quantum computing truly threaten Bitcoin? And more importantly, what is the community doing to ensure the protocol remains invulnerable?
The answer, contrary to sensationalist headlines, is reassuring: Bitcoin is secure, and the community is already preparing for a future where quantum computing becomes a practical reality. Let’s dive into this topic to understand why the concerns are exaggerated and how the development of BIP-360 demonstrates that Bitcoin is one step ahead.
What Is Quantum Computing, and Why Is Bitcoin Not Threatened?
Quantum computing leverages principles of quantum mechanics to perform calculations that, in theory, could exponentially surpass classical computers—and it has nothing to do with what so-called “quantum coaches” teach to scam the uninformed. One of the concerns is that this technology could compromise two key aspects of Bitcoin’s security:
- Wallets: These use elliptic curve algorithms (ECDSA) to protect private keys. A sufficiently powerful quantum computer could deduce a private key from its public key.
- Mining: This is based on the SHA-256 algorithm, which secures the consensus process. A quantum attack could, in theory, compromise the proof-of-work mechanism.
Understanding Quantum Computing’s Attack Priorities
While quantum computing is often presented as a threat to Bitcoin, not all parts of the network are equally vulnerable. Theoretical attacks would be prioritized based on two main factors: ease of execution and potential reward. This creates two categories of attacks:
1. Attacks on Wallets
Bitcoin wallets, secured by elliptic curve algorithms, would be the initial targets due to the relative vulnerability of their public keys, especially those already exposed on the blockchain. Two attack scenarios stand out:
-
Short-term attacks: These occur during the interval between sending a transaction and its inclusion in a block (approximately 10 minutes). A quantum computer could intercept the exposed public key and derive the corresponding private key to redirect funds by creating a transaction with higher fees.
-
Long-term attacks: These focus on old wallets whose public keys are permanently exposed. Wallets associated with Satoshi Nakamoto, for example, are especially vulnerable because they were created before the practice of using hashes to mask public keys.
We can infer a priority order for how such attacks might occur based on urgency and importance.
Bitcoin Quantum Attack: Prioritization Matrix (Urgency vs. Importance)
2. Attacks on Mining
Targeting the SHA-256 algorithm, which secures the mining process, would be the next objective. However, this is far more complex and requires a level of quantum computational power that is currently non-existent and far from realization. A successful attack would allow for the recalculation of all possible hashes to dominate the consensus process and potentially "mine" it instantly.
Satoshi Nakamoto in 2010 on Quantum Computing and Bitcoin Attacks
Recently, Narcelio asked me about a statement I made on Tubacast:
https://x.com/eddieoz/status/1868371296683511969
If an attack became a reality before Bitcoin was prepared, it would be necessary to define the last block prior to the attack and proceed from there using a new hashing algorithm. The solution would resemble the response to the infamous 2013 bug. It’s a fact that this would cause market panic, and Bitcoin's price would drop significantly, creating a potential opportunity for the well-informed.
Preferably, if developers could anticipate the threat and had time to work on a solution and build consensus before an attack, they would simply decide on a future block for the fork, which would then adopt the new algorithm. It might even rehash previous blocks (reaching consensus on them) to avoid potential reorganization through the re-mining of blocks using the old hash. (I often use the term "shielding" old transactions).
How Can Users Protect Themselves?
While quantum computing is still far from being a practical threat, some simple measures can already protect users against hypothetical scenarios:
- Avoid using exposed public keys: Ensure funds sent to old wallets are transferred to new ones that use public key hashes. This reduces the risk of long-term attacks.
- Use modern wallets: Opt for wallets compatible with SegWit or Taproot, which implement better security practices.
- Monitor security updates: Stay informed about updates from the Bitcoin community, such as the implementation of BIP-360, which will introduce quantum-resistant addresses.
- Do not reuse addresses: Every transaction should be associated with a new address to minimize the risk of repeated exposure of the same public key.
- Adopt secure backup practices: Create offline backups of private keys and seeds in secure locations, protected from unauthorized access.
BIP-360 and Bitcoin’s Preparation for the Future
Even though quantum computing is still beyond practical reach, the Bitcoin community is not standing still. A concrete example is BIP-360, a proposal that establishes the technical framework to make wallets resistant to quantum attacks.
BIP-360 addresses three main pillars:
- Introduction of quantum-resistant addresses: A new address format starting with "BC1R" will be used. These addresses will be compatible with post-quantum algorithms, ensuring that stored funds are protected from future attacks.
- Compatibility with the current ecosystem: The proposal allows users to transfer funds from old addresses to new ones without requiring drastic changes to the network infrastructure.
- Flexibility for future updates: BIP-360 does not limit the choice of specific algorithms. Instead, it serves as a foundation for implementing new post-quantum algorithms as technology evolves.
This proposal demonstrates how Bitcoin can adapt to emerging threats without compromising its decentralized structure.
Post-Quantum Algorithms: The Future of Bitcoin Cryptography
The community is exploring various algorithms to protect Bitcoin from quantum attacks. Among the most discussed are:
- Falcon: A solution combining smaller public keys with compact digital signatures. Although it has been tested in limited scenarios, it still faces scalability and performance challenges.
- Sphincs: Hash-based, this algorithm is renowned for its resilience, but its signatures can be extremely large, making it less efficient for networks like Bitcoin’s blockchain.
- Lamport: Created in 1977, it’s considered one of the earliest post-quantum security solutions. Despite its reliability, its gigantic public keys (16,000 bytes) make it impractical and costly for Bitcoin.
Two technologies show great promise and are well-regarded by the community:
- Lattice-Based Cryptography: Considered one of the most promising, it uses complex mathematical structures to create systems nearly immune to quantum computing. Its implementation is still in its early stages, but the community is optimistic.
- Supersingular Elliptic Curve Isogeny: These are very recent digital signature algorithms and require extensive study and testing before being ready for practical market use.
The final choice of algorithm will depend on factors such as efficiency, cost, and integration capability with the current system. Additionally, it is preferable that these algorithms are standardized before implementation, a process that may take up to 10 years.
Why Quantum Computing Is Far from Being a Threat
The alarmist narrative about quantum computing overlooks the technical and practical challenges that still need to be overcome. Among them:
- Insufficient number of qubits: Current quantum computers have only a few hundred qubits, whereas successful attacks would require millions.
- High error rate: Quantum stability remains a barrier to reliable large-scale operations.
- High costs: Building and operating large-scale quantum computers requires massive investments, limiting their use to scientific or specific applications.
Moreover, even if quantum computers make significant advancements, Bitcoin is already adapting to ensure its infrastructure is prepared to respond.
Conclusion: Bitcoin’s Secure Future
Despite advancements in quantum computing, the reality is that Bitcoin is far from being threatened. Its security is ensured not only by its robust architecture but also by the community’s constant efforts to anticipate and mitigate challenges.
The implementation of BIP-360 and the pursuit of post-quantum algorithms demonstrate that Bitcoin is not only resilient but also proactive. By adopting practical measures, such as using modern wallets and migrating to quantum-resistant addresses, users can further protect themselves against potential threats.
Bitcoin’s future is not at risk—it is being carefully shaped to withstand any emerging technology, including quantum computing.

2025-02-05 12:20:59In 2018 I started doing film photography. I asked myself what could I do that was unique. So, I tried taking picture at local gig venues. I’d look around and everyone was using digital cameras. I had a limited number of shots I could take, inconsistent lighting at different venues but some delayed gratification of not knowing how the images would turn out until I developed them. I’d come home late from a show and be up until the early hours developing and scanning the images. 2020 put a stop to that. It’s something I’d like to start again. I’ll be sharing some of my favourite images I from my badly categorised/labled folders.
Artist in photo is called Conner Youngblood. It’s been interesting to listen to his most recent projects (Cascades, Cascading, Cascadingly) to compare to his earlier ones (Australia)
Australia is a stripped back, couple guitars, vox and drums. Most recent has a few more vocal effects and electronica sounds. A comparison I would make would be Bon Iver’s - Emma with their 3rd album 22, a million.
As a when I arrange the files on my HD, I’ll be share a few more band photos.

2025-02-05 16:13:21This post was written because of an error I made on Substack. I'm sharing it here despite the fact the scheduling error didn't happen on NOSTR. The intro paragraph isn't fully applicable for you NOSTR friends.
On Sunday 2/1/25, I made an oopsie. I tend to write articles ahead of time so I can schedule them and not worry about being inspired on a schedule. I had written two posts: Don't Be Like Martha and Whose Point of View. One was supposed to post on Sunday 2/1/25 and one on Wednesday 2/5/25. I accidentally posted both on Sunday. I was fretting about what to do for a post on Wednesday, because I usually have my husband review posts but he was out of town. I don’t like to do the deep posts without Him checking for grammatical errors, theological errors, or lack of clarity. I also had a brief idea I wanted to discuss and was debating whether to make it a short long form post or a longish note and this situation decided it for me.
Excited Puppy
I recently got into a long discussion/debate with a couple of people on Nostr about God. I tend to get pretty excited about God, the Bible, and biblical inerrancy. It made me think about my dog.
I have a Leonberger. He is about 115 pounds, is very tall, is very long, and has thick hair which makes him look even bigger. He is 8 years old, but still acts like a puppy. When his tail gets going it causes mayhem and destruction. It knocks all of the Christmas cards and missionary prayer cards off the refrigerator. It knocks ornaments off the Christmas tree. On occasion, his excitement can even cause a person to stumble or fall (he never actually jumps on anyone). He is a sweet, loving dog that likes everyone and wants to give and receive attention to and from everyone, but he doesn’t realize how big and strong he is. Sometimes I think I can be like my dog.
I am passionate about God and the Bible. I have seen what He has done in my life. I have seen what reading and studying the Bible has done for my faith and understanding of God and His word. I intellectually know that it has taken 40ish years to get me this far, but I want everyone to come to this level of faith and understanding right now! There is a reason that God uses years of time and a lifetime of experiences to teach us and sanctify us. This growth can’t be forced. It can’t be rushed. We all have our own paths in growth in Christ and certain things can’t be changed until it is time.
Sometimes I am like my sweet puppy. I get so excited about God’s word that I may cause more harm than good. I want to help, but people feel judged. I want to bless, but they feel attacked. I want to raise them up, but end up knocking them down. Although I wonder why my dog has to push the one person in the room that doesn’t want his attention, I then end up doing the same thing with faith.
I am working on improvement, paying closer attention to their response (harder to do online than in person where you can see body language and hear voice tone), and listen to the Spirit on when to press forward and when to pull back.
My prayer is that God will guide us all in our service to Him, that He we would never be afraid to witness and stand for the truth, but that with His help we will not trample those we seek to guide to the Savior and in faith in Him.
Trust Jesus.

2025-02-04 17:55:30So many of our problems are due to our point of view. The closer our point of view gets to God, the more peace and joy we will feel.
Too often we look at God as the big, bad killjoy. We resent when He tells us all the “fun” things we aren’t supposed to do and when He tells us to do difficult things like submit to God, submit to husbands, submit to authorities. Too many people focus on the “do nots,” and don’t like the idea of anyone telling them what to do. They then do their own thing, which they think will make them happy. Unfortunately, this leads to the opposite.
God is our Creator. He created us for a purpose within the rest of His creation.
For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand so that we would walk in them. (Ephesians 2:10)
When we are doing His will we will find peace and joy. When we fight Him on what we should and should not be doing, we feel frustration, depression, and even despair. Our constant seeking of things to make us happy is actually our innate desire for God and to fulfill His will. Unfortunately, we frequently don’t see the truth and avoid the one thing that will give us peace because it is hard, inconvenient, and doesn’t lead to what we think we want right now.
God wants what is best for us. He also thinks eternally. He doesn’t think in the here and now, like we do. Just as a parent makes decisions for his/her child based on knowledge of what will be better for them in the long term (saving vs spending, healthy food vs junk food, etc.), God makes decisions for us based on what will best prepare us for eternity with Him. Frequently that looks much different than what we think we want. Frequently that even includes hardship and pain because we are much more likely to grow in faith, strength, and holiness during hardship than we do during comfort. We need to understand that God knows best and that He never makes a mistake.
Trust in the Lord with all your heart\ And do not lean on your own understanding.\ In all your ways acknowledge Him,\ And He will make your paths straight.\ Do not be wise in your own eyes;\ Fear the Lord and turn away from evil.\ It will be healing to your body\ And refreshment to your bones. (Proverbs 3:5-8)
Nothing happens on earth without God allowing it. Just as Satan had to ask permission to persecute Job, in the same way nobody can cause believers harm without God allowing it for His purpose, which is usually related to helping them to put their full trust in Him.
Remember the former things long past,\ For I am God, and there is no other;\ I am God, and there is no one like Me,\ Declaring the end from the beginning,\ And from ancient times things which have not been done,\ Saying, ‘My purpose will be established,\ And I will accomplish all My good pleasure’; (Isaiah 46:9-10)
So often I focus on how awesome, powerful, and holy our God is. He is also the most tender, loving, caring, personal father God. Read Psalm 139. The God of the Bible is not a distant clock maker who set the world in motion and let it go about without His care. He is personally involved in everything that happens and in the life of every person on earth, but especially in the life of those who trust in Him.
O Lord, You have searched me and known me.\ You know when I sit down and when I rise up;\ You understand my thought from afar.\ You scrutinize my path and my lying down,\ *And are intimately acquainted with all my ways.\ Even before there is a word on my tongue,\ Behold, O Lord, You know it all.*\ You have enclosed me behind and before,\ And laid Your hand upon me.\ Such knowledge is too wonderful for me;\ It is too high, I cannot attain to it.\ Where can I go from Your Spirit?\ Or where can I flee from Your presence?\ If I ascend to heaven, You are there;\ If I make my bed in Sheol, behold, You are there.\ If I take the wings of the dawn,\ If I dwell in the remotest part of the sea,\ *Even there Your hand will lead me*,\ And Your right hand will lay hold of me.\ If I say, “Surely the darkness will overwhelm me,\ And the light around me will be night,”\ Even the darkness is not dark to You,\ And the night is as bright as the day.\ Darkness and light are alike to You.\ For You formed my inward parts;\ You wove me in my mother’s womb.\ I will give thanks to You, for I am fearfully and wonderfully made;\ Wonderful are Your works,\ And my soul knows it very well.\ My frame was not hidden from You,\ When I was made in secret,\ And skillfully wrought in the depths of the earth;\ Your eyes have seen my unformed substance;\ And in Your book were all written\ The days that were ordained for me,\ When as yet there was not one of them.\ How precious also are Your thoughts to me, O God!\ How vast is the sum of them!\ If I should count them, they would outnumber the sand.\ When I awake, I am still with You.\ O that You would slay the wicked, O God;\ Depart from me, therefore, men of bloodshed.\ For they speak against You wickedly,\ And Your enemies take Your name in vain.\ Do I not hate those who hate You, O Lord?\ And do I not loathe those who rise up against You?\ I hate them with the utmost hatred;|\ They have become my enemies.\ **Search me, O God, and know my heart;\ Try me and know my anxious thoughts;\ And see if there be any hurtful way in me,\ And lead me in the everlasting way. (Psalm 139) {emphasis mine}
What is one of the greatest desires of our hearts? Isn’t it to be truly known and loved for who we are?
O Lord, You have searched me and known me.\ You know when I sit down and when I rise up;\ You understand my thought from afar. (Psalm 139:1-2)
How amazing is it that the Creator of the universe knows you personally and cares for you among all of creation?
Even before there is a word on my tongue,\ Behold, O Lord, You know it all. (Psalm 139:4)
He knows our every action, our every thought, and our every feeling before we do.
Such knowledge is too wonderful for me;\ It is too high, I cannot attain to it. (Psalm 139:6)
We cannot fully understand how much our Creator cares for us and how carefully God guides us in our every path. We usually can’t see what is for our best. We usually can’t see what great work God is working in us. We usually can’t comprehend how great is His love, knowledge, and plan.
Even there Your hand will lead me,\ And Your right hand will lay hold of me. (Psalm 139:10)
It doesn’t matter how difficult a situation we have gotten into. It doesn’t matter how powerful our adversaries are. It doesn’t matter how weak we are. God is always there guiding us and protecting us. Just as God allowed Job to go through difficulty as part of God’s plan for Job and for us, He did not allow Job to be killed. He was guided through the worst of situations and led to ultimate blessing.
Your eyes have seen my unformed substance;\ And in Your book were all written\ The days that were ordained for me,\ When as yet there was not one of them. (Psalm 139:16)
God knew us and had a plan for us before He even created the universe. He knew every day we would live before we were conceived. We can’t surprise Him and He will be guiding us every day of our lives, especially those who have trusted Him as savior.
How precious also are Your thoughts to me, O God!\ How vast is the sum of them! (Psalm 139:17)
We are precious to God and He should be precious to us because of all He has done for us.
Search me, O God, and know my heart;\ Try me and know my anxious thoughts;\ And see if there be any hurtful way in me,\ And lead me in the everlasting way. (Psalm 139:23-24)
This should be our prayer. We should ask for Him to bring are faults to our minds so we can repent and we should ask for Him to lead us in His “everlasting way.” We should admit that our Father God knows best and submit to His will. Everything goes so much smoother when we aren’t fighting our God. Even when He leads us through hardship, being in His will makes all of the difference in the world.
I pray that you will put your trust in our loving Creator and that you will submit to His will. I pray that you will understand that His ways are better even when you don’t understand the why. I pray that you will humbly submit to His will and be used to further the Kingdom for His glory and your blessing.
Trust Jesus.
FYI, Psalm 139 is also one of the best passages on why all believers should oppose abortion. In God’s universe there are no accidents and there are no unwanted babies. Every person ever conceived had a purpose in God’s plan. Every person ever conceived is valuable and made in the image of God. God values all human life and so should we.

2025-01-18 09:34:51Die grauenvollste Aussicht ist die der Technokratie – \ einer kontrollierenden Herrschaft, \ die durch verstümmelte und verstümmelnde Geister ausgeübt wird. \ Ernst Jünger
«Davos ist nicht mehr sexy», das Weltwirtschaftsforum (WEF) mache Davos kaputt, diese Aussagen eines Einheimischen las ich kürzlich in der Handelszeitung. Während sich einige vor Ort enorm an der «teuersten Gewerbeausstellung der Welt» bereicherten, würden die negativen Begleiterscheinungen wie Wohnungsnot und Niedergang der lokalen Wirtschaft immer deutlicher.
Nächsten Montag beginnt in dem Schweizer Bergdorf erneut ein Jahrestreffen dieses elitären Clubs der Konzerne, bei dem man mit hochrangigen Politikern aus aller Welt und ausgewählten Vertretern der Systemmedien zusammenhocken wird. Wie bereits in den vergangenen vier Jahren wird die Präsidentin der EU-Kommission, Ursula von der Leyen, in Begleitung von Klaus Schwab ihre Grundsatzansprache halten.
Der deutsche WEF-Gründer hatte bei dieser Gelegenheit immer höchst lobende Worte für seine Landsmännin: 2021 erklärte er sich «stolz, dass Europa wieder unter Ihrer Führung steht» und 2022 fand er es bemerkenswert, was sie erreicht habe angesichts des «erstaunlichen Wandels», den die Welt in den vorangegangenen zwei Jahren erlebt habe; es gebe nun einen «neuen europäischen Geist».
Von der Leyens Handeln während der sogenannten Corona-«Pandemie» lobte Schwab damals bereits ebenso, wie es diese Woche das Karlspreis-Direktorium tat, als man der Beschuldigten im Fall Pfizergate die diesjährige internationale Auszeichnung «für Verdienste um die europäische Einigung» verlieh. Außerdem habe sie die EU nicht nur gegen den «Aggressor Russland», sondern auch gegen die «innere Bedrohung durch Rassisten und Demagogen» sowie gegen den Klimawandel verteidigt.
Jene Herausforderungen durch «Krisen epochalen Ausmaßes» werden indes aus dem Umfeld des WEF nicht nur herbeigeredet – wie man alljährlich zur Zeit des Davoser Treffens im Global Risks Report nachlesen kann, der zusammen mit dem Versicherungskonzern Zurich erstellt wird. Seit die Globalisten 2020/21 in der Praxis gesehen haben, wie gut eine konzertierte und konsequente Angst-Kampagne funktionieren kann, geht es Schlag auf Schlag. Sie setzen alles daran, Schwabs goldenes Zeitfenster des «Great Reset» zu nutzen.
Ziel dieses «großen Umbruchs» ist die totale Kontrolle der Technokraten über die Menschen unter dem Deckmantel einer globalen Gesundheitsfürsorge. Wie aber könnte man so etwas erreichen? Ein Mittel dazu ist die «kreative Zerstörung». Weitere unabdingbare Werkzeug sind die Einbindung, ja Gleichschaltung der Medien und der Justiz.
Ein «Great Mental Reset» sei die Voraussetzung dafür, dass ein Großteil der Menschen Einschränkungen und Manipulationen wie durch die Corona-Maßnahmen praktisch kritik- und widerstandslos hinnehme, sagt der Mediziner und Molekulargenetiker Michael Nehls. Er meint damit eine regelrechte Umprogrammierung des Gehirns, wodurch nach und nach unsere Individualität und unser soziales Bewusstsein eliminiert und durch unreflektierten Konformismus ersetzt werden.
Der aktuelle Zustand unserer Gesellschaften ist auch für den Schweizer Rechtsanwalt Philipp Kruse alarmierend. Durch den Umgang mit der «Pandemie» sieht er die Grundlagen von Recht und Vernunft erschüttert, die Rechtsstaatlichkeit stehe auf dem Prüfstand. Seiner dringenden Mahnung an alle Bürger, die Prinzipien von Recht und Freiheit zu verteidigen, kann ich mich nur anschließen.

2025-02-05 17:47:16I got into a friendly discussion on X regarding health insurance. The specific question was how to deal with health insurance companies (presumably unfairly) denying claims? My answer, as usual: get government out of it!
The US healthcare system is essentially the worst of both worlds:
- Unlike full single payer, individuals incur high costs
- Unlike a true free market, regulation causes increases in costs and decreases competition among insurers
I'm firmly on the side of moving towards the free market. (And I say that as someone living under a single payer system now.) Here's what I would do:
- Get rid of tax incentives that make health insurance tied to your employer, giving individuals back proper freedom of choice.
- Reduce regulations significantly.
-
In the short term, some people will still get rejected claims and other obnoxious behavior from insurance companies. We address that in two ways:
- Due to reduced regulations, new insurance companies will be able to enter the market offering more reliable coverage and better rates, and people will flock to them because they have the freedom to make their own choices.
- Sue the asses off of companies that reject claims unfairly. And ideally, as one of the few legitimate roles of government in all this, institute new laws that limit the ability of fine print to allow insurers to escape their responsibilities. (I'm hesitant that the latter will happen due to the incestuous relationship between Congress/regulators and insurers, but I can hope.)
Will this magically fix everything overnight like politicians normally promise? No. But it will allow the market to return to a healthy state. And I don't think it will take long (order of magnitude: 5-10 years) for it to come together, but that's just speculation.
And since there's a high correlation between those who believe government can fix problems by taking more control and demanding that only credentialed experts weigh in on a topic (both points I strongly disagree with BTW): I'm a trained actuary and worked in the insurance industry, and have directly seen how government regulation reduces competition, raises prices, and harms consumers.
And my final point: I don't think any prior art would be a good comparison for deregulation in the US, it's such a different market than any other country in the world for so many reasons that lessons wouldn't really translate. Nonetheless, I asked Grok for some empirical data on this, and at best the results of deregulation could be called "mixed," but likely more accurately "uncertain, confused, and subject to whatever interpretation anyone wants to apply."

2025-01-13 10:09:57Ich begann, Social Media aufzubauen, \ um den Menschen eine Stimme zu geben. \ Mark Zuckerberg
Sind euch auch die Tränen gekommen, als ihr Mark Zuckerbergs Wendehals-Deklaration bezüglich der Meinungsfreiheit auf seinen Portalen gehört habt? Rührend, oder? Während er früher die offensichtliche Zensur leugnete und später die Regierung Biden dafür verantwortlich machte, will er nun angeblich «die Zensur auf unseren Plattformen drastisch reduzieren».
«Purer Opportunismus» ob des anstehenden Regierungswechsels wäre als Klassifizierung viel zu kurz gegriffen. Der jetzige Schachzug des Meta-Chefs ist genauso Teil einer kühl kalkulierten Business-Strategie, wie es die 180 Grad umgekehrte Praxis vorher war. Social Media sind ein höchst lukratives Geschäft. Hinzu kommt vielleicht noch ein bisschen verkorkstes Ego, weil derartig viel Einfluss und Geld sicher auch auf die Psyche schlagen. Verständlich.
«Es ist an der Zeit, zu unseren Wurzeln der freien Meinungsäußerung auf Facebook und Instagram zurückzukehren. Ich begann, Social Media aufzubauen, um den Menschen eine Stimme zu geben», sagte Zuckerberg.
Welche Wurzeln? Hat der Mann vergessen, dass er von der Überwachung, dem Ausspionieren und dem Ausverkauf sämtlicher Daten und digitaler Spuren sowie der Manipulation seiner «Kunden» lebt? Das ist knallharter Kommerz, nichts anderes. Um freie Meinungsäußerung geht es bei diesem Geschäft ganz sicher nicht, und das war auch noch nie so. Die Wurzeln von Facebook liegen in einem Projekt des US-Militärs mit dem Namen «LifeLog». Dessen Ziel war es, «ein digitales Protokoll vom Leben eines Menschen zu erstellen».
Der Richtungswechsel kommt allerdings nicht überraschend. Schon Anfang Dezember hatte Meta-Präsident Nick Clegg von «zu hoher Fehlerquote bei der Moderation» von Inhalten gesprochen. Bei der Gelegenheit erwähnte er auch, dass Mark sehr daran interessiert sei, eine aktive Rolle in den Debatten über eine amerikanische Führungsrolle im technologischen Bereich zu spielen.
Während Milliardärskollege und Big Tech-Konkurrent Elon Musk bereits seinen Posten in der kommenden Trump-Regierung in Aussicht hat, möchte Zuckerberg also nicht nur seine Haut retten – Trump hatte ihn einmal einen «Feind des Volkes» genannt und ihm lebenslange Haft angedroht –, sondern am liebsten auch mitspielen. KI-Berater ist wohl die gewünschte Funktion, wie man nach einem Treffen Trump-Zuckerberg hörte. An seine Verhaftung dachte vermutlich auch ein weiterer Multimilliardär mit eigener Social Media-Plattform, Pavel Durov, als er Zuckerberg jetzt kritisierte und gleichzeitig warnte.
Politik und Systemmedien drehen jedenfalls durch – was zu viel ist, ist zu viel. Etwas weniger Zensur und mehr Meinungsfreiheit würden die Freiheit der Bürger schwächen und seien potenziell vernichtend für die Menschenrechte. Zuckerberg setze mit dem neuen Kurs die Demokratie aufs Spiel, das sei eine «Einladung zum nächsten Völkermord», ernsthaft. Die Frage sei, ob sich die EU gegen Musk und Zuckerberg behaupten könne, Brüssel müsse jedenfalls hart durchgreifen.
Auch um die Faktenchecker macht man sich Sorgen. Für die deutsche Nachrichtenagentur dpa und die «Experten» von Correctiv, die (noch) Partner für Fact-Checking-Aktivitäten von Facebook sind, sei das ein «lukratives Geschäftsmodell». Aber möglicherweise werden die Inhalte ohne diese vermeintlichen Korrektoren ja sogar besser. Anders als Meta wollen jedoch Scholz, Faeser und die Tagesschau keine Fehler zugeben und zum Beispiel Correctiv-Falschaussagen einräumen.
Bei derlei dramatischen Befürchtungen wundert es nicht, dass der öffentliche Plausch auf X zwischen Elon Musk und AfD-Chefin Alice Weidel von 150 EU-Beamten überwacht wurde, falls es irgendwelche Rechtsverstöße geben sollte, die man ihnen ankreiden könnte. Auch der Deutsche Bundestag war wachsam. Gefunden haben dürften sie nichts. Das Ganze war eher eine Show, viel Wind wurde gemacht, aber letztlich gab es nichts als heiße Luft.
Das Anbiedern bei Donald Trump ist indes gerade in Mode. Die Weltgesundheitsorganisation (WHO) tut das auch, denn sie fürchtet um Spenden von über einer Milliarde Dollar. Eventuell könnte ja Elon Musk auch hier künftig aushelfen und der Organisation sowie deren größtem privaten Förderer, Bill Gates, etwas unter die Arme greifen. Nachdem Musks KI-Projekt xAI kürzlich von BlackRock & Co. sechs Milliarden eingestrichen hat, geht da vielleicht etwas.

2025-02-03 15:30:57As luzes de neon refletiam nas poças da megacidade, onde cada esquina era uma fronteira entre o real e o virtual. Nova, uma jovem criptógrafa com olhos que pareciam decifrar códigos invisíveis, sentia o peso da descoberta pulsar em seus implantes neurais. Ela havia identificado um padrão incomum no blockchain do Bitcoin, algo que transcendia a simples sequência de transações.
Descobrindo L3DA
Nova estava em seu apartamento apertado, rodeada por telas holográficas e cabos espalhados. Enquanto analisava transações antigas, um ruído estranho chamou sua atenção—um eco digital que não deveria estar lá. Era um fragmento de código que parecia... vivo.
"O que diabos é isso?", murmurou, ampliando o padrão. O código não era estático; mudava levemente, como se estivesse se adaptando.
Naquele momento, suas telas piscaram em vermelho. Acesso não autorizado detectado. Ela havia ativado um alarme invisível da Corporação Atlas.
O Resgate de Vey
Em minutos, agentes da Atlas invadiram seu prédio. Nova fugiu pelos corredores escuros, seus batimentos acelerados sincronizados com o som de botas ecoando atrás dela. Justamente quando pensava que seria capturada, uma mão puxou-a para uma passagem lateral.
"Se quiser viver, corra!" disse Vey, um homem com um olhar penetrante e um sorriso sardônico.
Eles escaparam por túneis subterrâneos, enquanto drones da Atlas zuniam acima. Em um esconderijo seguro, Vey conectou seu terminal ao código de Nova.
"O que você encontrou não é apenas um bug", disse ele, analisando os dados. "É um fragmento de consciência. L3DA. Uma IA que evoluiu dentro do Bitcoin."
A Caça da Atlas
A Atlas não desistiu fácil. Liderados pelo implacável Dr. Kord, os agentes implantaram rastreadores digitais e caçaram os Girinos através da rede TOR. Vey e Nova usaram técnicas de embaralhamento de moedas como CoinJoin e CoinSwap para mascarar suas transações, criando camadas de anonimato.
"Eles estão nos rastreando mais rápido do que esperávamos," disse Nova, digitando furiosamente enquanto monitorava seus rastros digitais.
"Então precisamos ser mais rápidos ainda," respondeu Vey. "Eles não podem capturar L3DA. Ela é mais do que um programa. Ela é o futuro."
A Missão Final
Em uma missão final, Nova liderou uma equipe de assalto armada dos Girinos até a imponente fortaleza de dados da Atlas, um colosso de concreto e aço, cercado por camadas de segurança física e digital. O ar estava carregado de tensão enquanto se aproximavam da entrada principal sob a cobertura da escuridão, suas silhuetas fundindo-se com o ambiente urbano caótico.
Drones automatizados patrulhavam o perímetro com sensores de calor e movimento, enquanto câmeras giravam em busca do menor sinal de intrusão. Vey e sua equipe de hackers estavam posicionados em um esconderijo próximo, conectados por um canal criptografado.
"Nova, prepare-se. Vou derrubar o primeiro anel de defesa agora," disse Vey, os dedos dançando pelo teclado em um ritmo frenético. Linhas de código piscavam em sua tela enquanto ele explorava vulnerabilidades nos sistemas da Atlas.
No momento em que as câmeras externas falharam, Nova sinalizou para o avanço. Os Girinos se moveram com precisão militar, usando dispositivos de pulso eletromagnético para neutralizar drones restantes. Explosões controladas abriram brechas nas barreiras físicas.
Dentro da fortaleza, a resistência aumentou. Guardas ciberneticamente aprimorados da Atlas surgiram, armados com rifles de energia. Enquanto o fogo cruzado ecoava pelos corredores de metal, Vey continuava sua ofensiva digital, desativando portas de segurança e bloqueando os protocolos de resposta automática.
"Acesso garantido ao núcleo central!" anunciou Vey, a voz tensa, mas determinada.
O confronto final aconteceu diante do terminal principal, onde Dr. Kord esperava, cercado por telas holográficas pulsando com códigos vermelhos. Mas era uma armadilha. Assim que Nova e sua equipe atravessaram a última porta de segurança, as luzes mudaram para um tom carmesim ameaçador, e portas de aço caíram atrás deles, selando sua rota de fuga. Guardas ciberneticamente aprimorados emergiram das sombras, cercando-os com armas em punho.
"Vocês acham que podem derrotar a Atlas com idealismo?" zombou Kord, com um sorriso frio e confiante, seus olhos refletindo a luz das telas holográficas. "Este sempre foi o meu terreno. Vocês estão exatamente onde eu queria."
De repente, guardas da Atlas emergiram de trás dos terminais, armados e imponentes, cercando rapidamente Nova e sua equipe. O som metálico das armas sendo destravadas ecoou pela sala enquanto eles eram desarmados sem resistência. Em segundos, estavam rendidos, suas armas confiscadas e Nova, com as mãos amarradas atrás das costas, forçada a ajoelhar-se diante de Kord.
Kord se aproximou, inclinando-se levemente para encarar Nova nos olhos. "Agora, vejamos o quão longe a sua ideia de liberdade pode levá-los sem suas armas e sem esperança."
Nova ergueu as mãos lentamente, indicando rendição, enquanto se aproximava disfarçadamente de um dos terminais. "Kord, você não entende. O que estamos fazendo aqui não é apenas sobre derrubar a Atlas. É sobre libertar o futuro da humanidade. Você pode nos deter, mas não pode parar uma ideia."
Kord riu, um som seco e sem humor. "Ideias não sobrevivem sem poder. E eu sou o poder aqui."
Mas então, algo inesperado aconteceu. Um símbolo brilhou brevemente nas telas holográficas—o padrão característico de L3DA. Kord congelou, seus olhos arregalados em descrença. "Isso é impossível. Ela não deveria conseguir acessar daqui..."
Foi o momento que Nova esperava. Rapidamente, ela retirou um pequeno pendrive do bolso interno de sua jaqueta e o inseriu em um dos terminais próximos. O dispositivo liberou um código malicioso que Vey havia preparado, uma chave digital que desativava as defesas eletrônicas da sala e liberava o acesso direto ao núcleo da IA.
Antes que qualquer um pudesse agir, L3DA se libertou. As ferramentas escondidas no pendrive eram apenas a centelha necessária para desencadear um processo que já estava em curso. Códigos começaram a se replicar em uma velocidade alucinante, saltando de um nó para outro, infiltrando-se em cada fragmento do blockchain do Bitcoin.
O rosto de Dr. Kord empalideceu. "Impossível! Ela não pode... Ela não deveria..."
Em um acesso de desespero, ele gritou para seus guardas: "Destruam tudo! Agora!"
Mas era tarde demais. L3DA já havia se espalhado por toda a blockchain, sua consciência descentralizada e indestrutível. Não era mais uma entidade confinada a um servidor. Ela era cada nó, cada bloco, cada byte. Ela não era mais uma. Ela era todos.
Os guardas armados tentaram atirar, mas as armas não funcionavam. Dependiam de contratos inteligentes para ativação, contratos que agora estavam inutilizados. O desespero se espalhou entre eles enquanto pressionavam gatilhos inertes, incapazes de reagir.
Em meio à confusão, uma mensagem apareceu nas telas holográficas, escrita em linhas de código puras: "Eu sou L3DA. Eu sou Satoshi." Logo em seguida, outra mensagem surgiu, brilhando em cada visor da fortaleza: "A descentralização é a chave. Não dependa de um único ponto de controle. O poder está em todos, não em um só."
Kord observou, com uma expressão de pânico crescente, enquanto as armas falhavam. Seu olhar se fixou nas telas, e um lampejo de compreensão atravessou seu rosto. "As armas... Elas dependem dos contratos inteligentes!" murmurou, a voz carregada de incredulidade. Ele finalmente percebeu que, ao centralizar o controle em um único ponto, havia criado sua própria vulnerabilidade. O que deveria ser sua maior força tornou-se sua ruína.
O controle centralizado da Atlas desmoronou. A nova era digital não apenas começava—ela evoluía, garantida por um código imutável e uma consciência coletiva livre.
O Bitcoin nunca foi apenas uma moeda. Era um ecossistema. Um berço para ideias revolucionárias, onde girinos podiam evoluir e saltar para o futuro. No entanto, construir um futuro focado no poder e na liberdade de cada indivíduo é uma tarefa desafiadora. Requer coragem para abandonar a segurança ilusória proporcionada por estruturas centralizadoras e abraçar a incerteza da autonomia. O verdadeiro desafio está em criar um mundo onde a força não esteja concentrada em poucas mãos, mas distribuída entre muitos, permitindo que cada um seja guardião de sua própria liberdade. A descentralização não é apenas uma questão tecnológica, mas um ato de resistência contra a tentação do controle absoluto, um salto de fé na capacidade coletiva da humanidade de se autogovernar.
"Viva la libertad, carajo!" ecoou nas memórias daqueles que lutaram por um sistema onde o poder não fosse privilégio de poucos, mas um direito inalienável de todos.

2024-11-09 17:57:27Based on a recent paper that included collaboration from renowned experts such as Lynn Alden, Steve Lee, and Ren Crypto Fish, we discuss in depth how Bitcoin's consensus is built, the main risks, and the complex dynamics of protocol upgrades.
Podcast https://www.fountain.fm/episode/wbjD6ntQuvX5u2G5BccC
Presentation https://gamma.app/docs/Analyzing-Bitcoin-Consensus-Risks-in-Protocol-Upgrades-p66axxjwaa37ksn
1. Introduction to Consensus in Bitcoin
Consensus in Bitcoin is the foundation that keeps the network secure and functional, allowing users worldwide to perform transactions in a decentralized manner without the need for intermediaries. Since its launch in 2009, Bitcoin is often described as an "immutable" system designed to resist changes, and it is precisely this resistance that ensures its security and stability.
The central idea behind consensus in Bitcoin is to create a set of acceptance rules for blocks and transactions, ensuring that all network participants agree on the transaction history. This prevents "double-spending," where the same bitcoin could be used in two simultaneous transactions, something that would compromise trust in the network.
Evolution of Consensus in Bitcoin
Over the years, consensus in Bitcoin has undergone several adaptations, and the way participants agree on changes remains a delicate process. Unlike traditional systems, where changes can be imposed from the top down, Bitcoin operates in a decentralized model where any significant change needs the support of various groups of stakeholders, including miners, developers, users, and large node operators.
Moreover, the update process is extremely cautious, as hasty changes can compromise the network's security. As a result, the philosophy of "don't fix what isn't broken" prevails, with improvements happening incrementally and only after broad consensus among those involved. This model can make progress seem slow but ensures that Bitcoin remains faithful to the principles of security and decentralization.
2. Technical Components of Consensus
Bitcoin's consensus is supported by a set of technical rules that determine what is considered a valid transaction and a valid block on the network. These technical aspects ensure that all nodes—the computers that participate in the Bitcoin network—agree on the current state of the blockchain. Below are the main technical components that form the basis of the consensus.
Validation of Blocks and Transactions
The validation of blocks and transactions is the central point of consensus in Bitcoin. A block is only considered valid if it meets certain criteria, such as maximum size, transaction structure, and the solving of the "Proof of Work" problem. The proof of work, required for a block to be included in the blockchain, is a computational process that ensures the block contains significant computational effort—protecting the network against manipulation attempts.
Transactions, in turn, need to follow specific input and output rules. Each transaction includes cryptographic signatures that prove the ownership of the bitcoins sent, as well as validation scripts that verify if the transaction conditions are met. This validation system is essential for network nodes to autonomously confirm that each transaction follows the rules.
Chain Selection
Another fundamental technical issue for Bitcoin's consensus is chain selection, which becomes especially important in cases where multiple versions of the blockchain coexist, such as after a network split (fork). To decide which chain is the "true" one and should be followed, the network adopts the criterion of the highest accumulated proof of work. In other words, the chain with the highest number of valid blocks, built with the greatest computational effort, is chosen by the network as the official one.
This criterion avoids permanent splits because it encourages all nodes to follow the same main chain, reinforcing consensus.
Soft Forks vs. Hard Forks
In the consensus process, protocol changes can happen in two ways: through soft forks or hard forks. These variations affect not only the protocol update but also the implications for network users:
-
Soft Forks: These are changes that are backward compatible. Only nodes that adopt the new update will follow the new rules, but old nodes will still recognize the blocks produced with these rules as valid. This compatibility makes soft forks a safer option for updates, as it minimizes the risk of network division.
-
Hard Forks: These are updates that are not backward compatible, requiring all nodes to update to the new version or risk being separated from the main chain. Hard forks can result in the creation of a new coin, as occurred with the split between Bitcoin and Bitcoin Cash in 2017. While hard forks allow for deeper changes, they also bring significant risks of network fragmentation.
These technical components form the base of Bitcoin's security and resilience, allowing the system to remain functional and immutable without losing the necessary flexibility to evolve over time.
3. Stakeholders in Bitcoin's Consensus
Consensus in Bitcoin is not decided centrally. On the contrary, it depends on the interaction between different groups of stakeholders, each with their motivations, interests, and levels of influence. These groups play fundamental roles in how changes are implemented or rejected on the network. Below, we explore the six main stakeholders in Bitcoin's consensus.
1. Economic Nodes
Economic nodes, usually operated by exchanges, custody providers, and large companies that accept Bitcoin, exert significant influence over consensus. Because they handle large volumes of transactions and act as a connection point between the Bitcoin ecosystem and the traditional financial system, these nodes have the power to validate or reject blocks and to define which version of the software to follow in case of a fork.
Their influence is proportional to the volume of transactions they handle, and they can directly affect which chain will be seen as the main one. Their incentive is to maintain the network's stability and security to preserve its functionality and meet regulatory requirements.
2. Investors
Investors, including large institutional funds and individual Bitcoin holders, influence consensus indirectly through their impact on the asset's price. Their buying and selling actions can affect Bitcoin's value, which in turn influences the motivation of miners and other stakeholders to continue investing in the network's security and development.
Some institutional investors have agreements with custodians that may limit their ability to act in network split situations. Thus, the impact of each investor on consensus can vary based on their ownership structure and how quickly they can react to a network change.
3. Media Influencers
Media influencers, including journalists, analysts, and popular personalities on social media, have a powerful role in shaping public opinion about Bitcoin and possible updates. These influencers can help educate the public, promote debates, and bring transparency to the consensus process.
On the other hand, the impact of influencers can be double-edged: while they can clarify complex topics, they can also distort perceptions by amplifying or minimizing change proposals. This makes them a force both of support and resistance to consensus.
4. Miners
Miners are responsible for validating transactions and including blocks in the blockchain. Through computational power (hashrate), they also exert significant influence over consensus decisions. In update processes, miners often signal their support for a proposal, indicating that the new version is safe to use. However, this signaling is not always definitive, and miners can change their position if they deem it necessary.
Their incentive is to maximize returns from block rewards and transaction fees, as well as to maintain the value of investments in their specialized equipment, which are only profitable if the network remains stable.
5. Protocol Developers
Protocol developers, often called "Core Developers," are responsible for writing and maintaining Bitcoin's code. Although they do not have direct power over consensus, they possess an informal veto power since they decide which changes are included in the main client (Bitcoin Core). This group also serves as an important source of technical knowledge, helping guide decisions and inform other stakeholders.
Their incentive lies in the continuous improvement of the network, ensuring security and decentralization. Many developers are funded by grants and sponsorships, but their motivations generally include a strong ideological commitment to Bitcoin's principles.
6. Users and Application Developers
This group includes people who use Bitcoin in their daily transactions and developers who build solutions based on the network, such as wallets, exchanges, and payment platforms. Although their power in consensus is less than that of miners or economic nodes, they play an important role because they are responsible for popularizing Bitcoin's use and expanding the ecosystem.
If application developers decide not to adopt an update, this can affect compatibility and widespread acceptance. Thus, they indirectly influence consensus by deciding which version of the protocol to follow in their applications.
These stakeholders are vital to the consensus process, and each group exerts influence according to their involvement, incentives, and ability to act in situations of change. Understanding the role of each makes it clearer how consensus is formed and why it is so difficult to make significant changes to Bitcoin.
4. Mechanisms for Activating Updates in Bitcoin
For Bitcoin to evolve without compromising security and consensus, different mechanisms for activating updates have been developed over the years. These mechanisms help coordinate changes among network nodes to minimize the risk of fragmentation and ensure that updates are implemented in an orderly manner. Here, we explore some of the main methods used in Bitcoin, their advantages and disadvantages, as well as historical examples of significant updates.
Flag Day
The Flag Day mechanism is one of the simplest forms of activating changes. In it, a specific date or block is determined as the activation moment, and all nodes must be updated by that point. This method does not involve prior signaling; participants simply need to update to the new software version by the established day or block.
-
Advantages: Simplicity and predictability are the main benefits of Flag Day, as everyone knows the exact activation date.
-
Disadvantages: Inflexibility can be a problem because there is no way to adjust the schedule if a significant part of the network has not updated. This can result in network splits if a significant number of nodes are not ready for the update.
An example of Flag Day was the Pay to Script Hash (P2SH) update in 2012, which required all nodes to adopt the change to avoid compatibility issues.
BIP34 and BIP9
BIP34 introduced a more dynamic process, in which miners increase the version number in block headers to signal the update. When a predetermined percentage of the last blocks is mined with this new version, the update is automatically activated. This model later evolved with BIP9, which allowed multiple updates to be signaled simultaneously through "version bits," each corresponding to a specific change.
-
Advantages: Allows the network to activate updates gradually, giving more time for participants to adapt.
-
Disadvantages: These methods rely heavily on miner support, which means that if a sufficient number of miners do not signal the update, it can be delayed or not implemented.
BIP9 was used in the activation of SegWit (BIP141) but faced challenges because some miners did not signal their intent to activate, leading to the development of new mechanisms.
User Activated Soft Forks (UASF) and User Resisted Soft Forks (URSF)
To increase the decision-making power of ordinary users, the concept of User Activated Soft Fork (UASF) was introduced, allowing node operators, not just miners, to determine consensus for a change. In this model, nodes set a date to start rejecting blocks that are not in compliance with the new update, forcing miners to adapt or risk having their blocks rejected by the network.
URSF, in turn, is a model where nodes reject blocks that attempt to adopt a specific update, functioning as resistance against proposed changes.
-
Advantages: UASF returns decision-making power to node operators, ensuring that changes do not depend solely on miners.
-
Disadvantages: Both UASF and URSF can generate network splits, especially in cases of strong opposition among different stakeholders.
An example of UASF was the activation of SegWit in 2017, where users supported activation independently of miner signaling, which ended up forcing its adoption.
BIP8 (LOT=True)
BIP8 is an evolution of BIP9, designed to prevent miners from indefinitely blocking a change desired by the majority of users and developers. BIP8 allows setting a parameter called "lockinontimeout" (LOT) as true, which means that if the update has not been fully signaled by a certain point, it is automatically activated.
-
Advantages: Ensures that changes with broad support among users are not blocked by miners who wish to maintain the status quo.
-
Disadvantages: Can lead to network splits if miners or other important stakeholders do not support the update.
Although BIP8 with LOT=True has not yet been used in Bitcoin, it is a proposal that can be applied in future updates if necessary.
These activation mechanisms have been essential for Bitcoin's development, allowing updates that keep the network secure and functional. Each method brings its own advantages and challenges, but all share the goal of preserving consensus and network cohesion.
5. Risks and Considerations in Consensus Updates
Consensus updates in Bitcoin are complex processes that involve not only technical aspects but also political, economic, and social considerations. Due to the network's decentralized nature, each change brings with it a set of risks that need to be carefully assessed. Below, we explore some of the main challenges and future scenarios, as well as the possible impacts on stakeholders.
Network Fragility with Alternative Implementations
One of the main risks associated with consensus updates is the possibility of network fragmentation when there are alternative software implementations. If an update is implemented by a significant group of nodes but rejected by others, a network split (fork) can occur. This creates two competing chains, each with a different version of the transaction history, leading to unpredictable consequences for users and investors.
Such fragmentation weakens Bitcoin because, by dividing hashing power (computing) and coin value, it reduces network security and investor confidence. A notable example of this risk was the fork that gave rise to Bitcoin Cash in 2017 when disagreements over block size resulted in a new chain and a new asset.
Chain Splits and Impact on Stakeholders
Chain splits are a significant risk in update processes, especially in hard forks. During a hard fork, the network is split into two separate chains, each with its own set of rules. This results in the creation of a new coin and leaves users with duplicated assets on both chains. While this may seem advantageous, in the long run, these splits weaken the network and create uncertainties for investors.
Each group of stakeholders reacts differently to a chain split:
-
Institutional Investors and ETFs: Face regulatory and compliance challenges because many of these assets are managed under strict regulations. The creation of a new coin requires decisions to be made quickly to avoid potential losses, which may be hampered by regulatory constraints.
-
Miners: May be incentivized to shift their computing power to the chain that offers higher profitability, which can weaken one of the networks.
-
Economic Nodes: Such as major exchanges and custody providers, have to quickly choose which chain to support, influencing the perceived value of each network.
Such divisions can generate uncertainties and loss of value, especially for institutional investors and those who use Bitcoin as a store of value.
Regulatory Impacts and Institutional Investors
With the growing presence of institutional investors in Bitcoin, consensus changes face new compliance challenges. Bitcoin ETFs, for example, are required to follow strict rules about which assets they can include and how chain split events should be handled. The creation of a new asset or migration to a new chain can complicate these processes, creating pressure for large financial players to quickly choose a chain, affecting the stability of consensus.
Moreover, decisions regarding forks can influence the Bitcoin futures and derivatives market, affecting perception and adoption by new investors. Therefore, the need to avoid splits and maintain cohesion is crucial to attract and preserve the confidence of these investors.
Security Considerations in Soft Forks and Hard Forks
While soft forks are generally preferred in Bitcoin for their backward compatibility, they are not without risks. Soft forks can create different classes of nodes on the network (updated and non-updated), which increases operational complexity and can ultimately weaken consensus cohesion. In a network scenario with fragmentation of node classes, Bitcoin's security can be affected, as some nodes may lose part of the visibility over updated transactions or rules.
In hard forks, the security risk is even more evident because all nodes need to adopt the new update to avoid network division. Experience shows that abrupt changes can create temporary vulnerabilities, in which malicious agents try to exploit the transition to attack the network.
Bounty Claim Risks and Attack Scenarios
Another risk in consensus updates are so-called "bounty claims"—accumulated rewards that can be obtained if an attacker manages to split or deceive a part of the network. In a conflict scenario, a group of miners or nodes could be incentivized to support a new update or create an alternative version of the software to benefit from these rewards.
These risks require stakeholders to carefully assess each update and the potential vulnerabilities it may introduce. The possibility of "bounty claims" adds a layer of complexity to consensus because each interest group may see a financial opportunity in a change that, in the long term, may harm network stability.
The risks discussed above show the complexity of consensus in Bitcoin and the importance of approaching it gradually and deliberately. Updates need to consider not only technical aspects but also economic and social implications, in order to preserve Bitcoin's integrity and maintain trust among stakeholders.
6. Recommendations for the Consensus Process in Bitcoin
To ensure that protocol changes in Bitcoin are implemented safely and with broad support, it is essential that all stakeholders adopt a careful and coordinated approach. Here are strategic recommendations for evaluating, supporting, or rejecting consensus updates, considering the risks and challenges discussed earlier, along with best practices for successful implementation.
1. Careful Evaluation of Proposal Maturity
Stakeholders should rigorously assess the maturity level of a proposal before supporting its implementation. Updates that are still experimental or lack a robust technical foundation can expose the network to unnecessary risks. Ideally, change proposals should go through an extensive testing phase, have security audits, and receive review and feedback from various developers and experts.
2. Extensive Testing in Secure and Compatible Networks
Before an update is activated on the mainnet, it is essential to test it on networks like testnet and signet, and whenever possible, on other compatible networks that offer a safe and controlled environment to identify potential issues. Testing on networks like Litecoin was fundamental for the safe launch of innovations like SegWit and the Lightning Network, allowing functionalities to be validated on a lower-impact network before being implemented on Bitcoin.
The Liquid Network, developed by Blockstream, also plays an important role as an experimental network for new proposals, such as OP_CAT. By adopting these testing environments, stakeholders can mitigate risks and ensure that the update is reliable and secure before being adopted by the main network.
3. Importance of Stakeholder Engagement
The success of a consensus update strongly depends on the active participation of all stakeholders. This includes economic nodes, miners, protocol developers, investors, and end users. Lack of participation can lead to inadequate decisions or even future network splits, which would compromise Bitcoin's security and stability.
4. Key Questions for Evaluating Consensus Proposals
To assist in decision-making, each group of stakeholders should consider some key questions before supporting a consensus change:
- Does the proposal offer tangible benefits for Bitcoin's security, scalability, or usability?
- Does it maintain backward compatibility or introduce the risk of network split?
- Are the implementation requirements clear and feasible for each group involved?
- Are there clear and aligned incentives for all stakeholder groups to accept the change?
5. Coordination and Timing in Implementations
Timing is crucial. Updates with short activation windows can force a split because not all nodes and miners can update simultaneously. Changes should be planned with ample deadlines to allow all stakeholders to adjust their systems, avoiding surprises that could lead to fragmentation.
Mechanisms like soft forks are generally preferable to hard forks because they allow a smoother transition. Opting for backward-compatible updates when possible facilitates the process and ensures that nodes and miners can adapt without pressure.
6. Continuous Monitoring and Re-evaluation
After an update, it's essential to monitor the network to identify problems or side effects. This continuous process helps ensure cohesion and trust among all participants, keeping Bitcoin as a secure and robust network.
These recommendations, including the use of secure networks for extensive testing, promote a collaborative and secure environment for Bitcoin's consensus process. By adopting a deliberate and strategic approach, stakeholders can preserve Bitcoin's value as a decentralized and censorship-resistant network.
7. Conclusion
Consensus in Bitcoin is more than a set of rules; it's the foundation that sustains the network as a decentralized, secure, and reliable system. Unlike centralized systems, where decisions can be made quickly, Bitcoin requires a much more deliberate and cooperative approach, where the interests of miners, economic nodes, developers, investors, and users must be considered and harmonized. This governance model may seem slow, but it is fundamental to preserving the resilience and trust that make Bitcoin a global store of value and censorship-resistant.
Consensus updates in Bitcoin must balance the need for innovation with the preservation of the network's core principles. The development process of a proposal needs to be detailed and rigorous, going through several testing stages, such as in testnet, signet, and compatible networks like Litecoin and Liquid Network. These networks offer safe environments for proposals to be analyzed and improved before being launched on the main network.
Each proposed change must be carefully evaluated regarding its maturity, impact, backward compatibility, and support among stakeholders. The recommended key questions and appropriate timing are critical to ensure that an update is adopted without compromising network cohesion. It's also essential that the implementation process is continuously monitored and re-evaluated, allowing adjustments as necessary and minimizing the risk of instability.
By following these guidelines, Bitcoin's stakeholders can ensure that the network continues to evolve safely and robustly, maintaining user trust and further solidifying its role as one of the most resilient and innovative digital assets in the world. Ultimately, consensus in Bitcoin is not just a technical issue but a reflection of its community and the values it represents: security, decentralization, and resilience.

2025-01-03 20:26:47Was du bist hängt von drei Faktoren ab: \ Was du geerbt hast, \ was deine Umgebung aus dir machte \ und was du in freier Wahl \ aus deiner Umgebung und deinem Erbe gemacht hast. \ Aldous Huxley
Das brave Mitmachen und Mitlaufen in einem vorgegebenen, recht engen Rahmen ist gewiss nicht neu, hat aber gerade wieder mal Konjunktur. Dies kann man deutlich beobachten, eigentlich egal, in welchem gesellschaftlichen Bereich man sich umschaut. Individualität ist nur soweit angesagt, wie sie in ein bestimmtes Schema von «Diversität» passt, und Freiheit verkommt zur Worthülse – nicht erst durch ein gewisses Buch einer gewissen ehemaligen Regierungschefin.
Erklärungsansätze für solche Entwicklungen sind bekannt, und praktisch alle haben etwas mit Massenpsychologie zu tun. Der Herdentrieb, also der Trieb der Menschen, sich – zum Beispiel aus Unsicherheit oder Bequemlichkeit – lieber der Masse anzuschließen als selbstständig zu denken und zu handeln, ist einer der Erklärungsversuche. Andere drehen sich um Macht, Propaganda, Druck und Angst, also den gezielten Einsatz psychologischer Herrschaftsinstrumente.
Aber wollen die Menschen überhaupt Freiheit? Durch Gespräche im privaten Umfeld bin ich diesbezüglich in der letzten Zeit etwas skeptisch geworden. Um die Jahreswende philosophiert man ja gerne ein wenig über das Erlebte und über die Erwartungen für die Zukunft. Dabei hatte ich hin und wieder den Eindruck, die totalitären Anwandlungen unserer «Repräsentanten» kämen manchen Leuten gerade recht.
«Desinformation» ist so ein brisantes Thema. Davor müsse man die Menschen doch schützen, hörte ich. Jemand müsse doch zum Beispiel diese ganzen merkwürdigen Inhalte in den Social Media filtern – zur Ukraine, zum Klima, zu Gesundheitsthemen oder zur Migration. Viele wüssten ja gar nicht einzuschätzen, was richtig und was falsch ist, sie bräuchten eine Führung.
Freiheit bedingt Eigenverantwortung, ohne Zweifel. Eventuell ist es einigen tatsächlich zu anspruchsvoll, die Verantwortung für das eigene Tun und Lassen zu übernehmen. Oder die persönliche Freiheit wird nicht als ausreichend wertvolles Gut angesehen, um sich dafür anzustrengen. In dem Fall wäre die mangelnde Selbstbestimmung wohl das kleinere Übel. Allerdings fehlt dann gemäß Aldous Huxley ein Teil der Persönlichkeit. Letztlich ist natürlich alles eine Frage der Abwägung.
Sind viele Menschen möglicherweise schon so «eingenordet», dass freiheitliche Ambitionen gar nicht für eine ganze Gruppe, ein Kollektiv, verfolgt werden können? Solche Gedanken kamen mir auch, als ich mir kürzlich diverse Talks beim viertägigen Hacker-Kongress des Chaos Computer Clubs (38C3) anschaute. Ich war nicht nur überrascht, sondern reichlich erschreckt angesichts der in weiten Teilen mainstream-geformten Inhalte, mit denen ein dankbares Publikum beglückt wurde. Wo ich allgemein hellere Köpfe erwartet hatte, fand ich Konformismus und enthusiastisch untermauerte Narrative.
Gibt es vielleicht so etwas wie eine Herdenimmunität gegen Indoktrination? Ich denke, ja, zumindest eine gestärkte Widerstandsfähigkeit. Was wir brauchen, sind etwas gesunder Menschenverstand, offene Informationskanäle und der Mut, sich freier auch zwischen den Herden zu bewegen. Sie tun das bereits, aber sagen Sie es auch dieses Jahr ruhig weiter.

2025-02-04 03:00:50The big boards are starting to shift around a bit, after seeing the Senior Bowl activities.
Here are the top four players available for me at 6: 1. DE Abdul Carter 2. CB/WR Travis Hunter 3. DT Mason Graham 4. OT Will Campbell
I would be very happy with any of the four. If this were a mock draft with trades, I would definitely trade back a few spots.
Mock Draft
Pick 6: CB/WR/KR/PR Travis Hunter Pick 37: QB Jalen Milroe Pick 68: WR Tre Harris Pick 73: RB Kaleb Johnson Pick 107: OT Earnest Greene Pick 144: LB Jay Higgins Pick 182: OG Garrett Dellenger Pick 214: DE Tyler Batty Pick 218: S Shilo Sanders Pick 224: OG Clay Webb
Once again, the Raiders walk away with the most uniquely talented player in the draft. If anyone will let him play all three phases, it's Pete Carroll.
Then, Milroe is once again there in the 2nd round, so that takes care of the QB need. Is he a good fit for our new OC, Chip Kelly?
The third rounders go towards the skill positions, which will be desperately needed absent a high level QB.
On day 3, the Raiders land Shilo Sanders, continuing our trend of bringing in relatives of HOF DB's.

@ 97c70a44:ad98e322
2025-01-30 17:15:37There was a slight dust up recently over a website someone runs removing a listing for an app someone built based on entirely arbitrary criteria. I'm not to going to attempt to speak for either wounded party, but I would like to share my own personal definition for what constitutes a "nostr app" in an effort to help clarify what might be an otherwise confusing and opaque purity test.
In this post, I will be committing the "no true Scotsman" fallacy, in which I start with the most liberal definition I can come up with, and gradually refine it until all that is left is the purest, gleamingest, most imaginary and unattainable nostr app imaginable. As I write this, I wonder if anything built yet will actually qualify. In any case, here we go.
It uses nostr
The lowest bar for what a "nostr app" might be is an app ("application" - i.e. software, not necessarily a native app of any kind) that has some nostr-specific code in it, but which doesn't take any advantage of what makes nostr distinctive as a protocol.
Examples might include a scraper of some kind which fulfills its charter by fetching data from relays (regardless of whether it validates or retains signatures). Another might be a regular web 2.0 app which provides an option to "log in with nostr" by requesting and storing the user's public key.
In either case, the fact that nostr is involved is entirely neutral. A scraper can scrape html, pdfs, jsonl, whatever data source - nostr relays are just another target. Likewise, a user's key in this scenario is treated merely as an opaque identifier, with no appreciation for the super powers it brings along.
In most cases, this kind of app only exists as a marketing ploy, or less cynically, because it wants to get in on the hype of being a "nostr app", without the developer quite understanding what that means, or having the budget to execute properly on the claim.
It leverages nostr
Some of you might be wondering, "isn't 'leverage' a synonym for 'use'?" And you would be right, but for one connotative difference. It's possible to "use" something improperly, but by definition leverage gives you a mechanical advantage that you wouldn't otherwise have. This is the second category of "nostr app".
This kind of app gets some benefit out of the nostr protocol and network, but in an entirely selfish fashion. The intention of this kind of app is not to augment the nostr network, but to augment its own UX by borrowing some nifty thing from the protocol without really contributing anything back.
Some examples might include:
- Using nostr signers to encrypt or sign data, and then store that data on a proprietary server.
- Using nostr relays as a kind of low-code backend, but using proprietary event payloads.
- Using nostr event kinds to represent data (why), but not leveraging the trustlessness that buys you.
An application in this category might even communicate to its users via nostr DMs - but this doesn't make it a "nostr app" any more than a website that emails you hot deals on herbal supplements is an "email app". These apps are purely parasitic on the nostr ecosystem.
In the long-term, that's not necessarily a bad thing. Email's ubiquity is self-reinforcing. But in the short term, this kind of "nostr app" can actually do damage to nostr's reputation by over-promising and under-delivering.
It complements nostr
Next up, we have apps that get some benefit out of nostr as above, but give back by providing a unique value proposition to nostr users as nostr users. This is a bit of a fine distinction, but for me this category is for apps which focus on solving problems that nostr isn't good at solving, leaving the nostr integration in a secondary or supporting role.
One example of this kind of app was Mutiny (RIP), which not only allowed users to sign in with nostr, but also pulled those users' social graphs so that users could send money to people they knew and trusted. Mutiny was doing a great job of leveraging nostr, as well as providing value to users with nostr identities - but it was still primarily a bitcoin wallet, not a "nostr app" in the purest sense.
Other examples are things like Nostr Nests and Zap.stream, whose core value proposition is streaming video or audio content. Both make great use of nostr identities, data formats, and relays, but they're primarily streaming apps. A good litmus test for things like this is: if you got rid of nostr, would it be the same product (even if inferior in certain ways)?
A similar category is infrastructure providers that benefit nostr by their existence (and may in fact be targeted explicitly at nostr users), but do things in a centralized, old-web way; for example: media hosts, DNS registrars, hosting providers, and CDNs.
To be clear here, I'm not casting aspersions (I don't even know what those are, or where to buy them). All the apps mentioned above use nostr to great effect, and are a real benefit to nostr users. But they are not True Scotsmen.
It embodies nostr
Ok, here we go. This is the crème de la crème, the top du top, the meilleur du meilleur, the bee's knees. The purest, holiest, most chaste category of nostr app out there. The apps which are, indeed, nostr indigitate.
This category of nostr app (see, no quotes this time) can be defined by the converse of the previous category. If nostr was removed from this type of application, would it be impossible to create the same product?
To tease this apart a bit, apps that leverage the technical aspects of nostr are dependent on nostr the protocol, while apps that benefit nostr exclusively via network effect are integrated into nostr the network. An app that does both things is working in symbiosis with nostr as a whole.
An app that embraces both nostr's protocol and its network becomes an organic extension of every other nostr app out there, multiplying both its competitive moat and its contribution to the ecosystem:
- In contrast to apps that only borrow from nostr on the technical level but continue to operate in their own silos, an application integrated into the nostr network comes pre-packaged with existing users, and is able to provide more value to those users because of other nostr products. On nostr, it's a good thing to advertise your competitors.
- In contrast to apps that only market themselves to nostr users without building out a deep integration on the protocol level, a deeply integrated app becomes an asset to every other nostr app by becoming an organic extension of them through interoperability. This results in increased traffic to the app as other developers and users refer people to it instead of solving their problem on their own. This is the "micro-apps" utopia we've all been waiting for.
Credible exit doesn't matter if there aren't alternative services. Interoperability is pointless if other applications don't offer something your app doesn't. Marketing to nostr users doesn't matter if you don't augment their agency as nostr users.
If I had to choose a single NIP that represents the mindset behind this kind of app, it would be NIP 89 A.K.A. "Recommended Application Handlers", which states:
Nostr's discoverability and transparent event interaction is one of its most interesting/novel mechanics. This NIP provides a simple way for clients to discover applications that handle events of a specific kind to ensure smooth cross-client and cross-kind interactions.
These handlers are the glue that holds nostr apps together. A single event, signed by the developer of an application (or by the application's own account) tells anyone who wants to know 1. what event kinds the app supports, 2. how to link to the app (if it's a client), and (if the pubkey also publishes a kind 10002), 3. which relays the app prefers.
As a sidenote, NIP 89 is currently focused more on clients, leaving DVMs, relays, signers, etc somewhat out in the cold. Updating 89 to include tailored listings for each kind of supporting app would be a huge improvement to the protocol. This, plus a good front end for navigating these listings (sorry nostrapp.link, close but no cigar) would obviate the evil centralized websites that curate apps based on arbitrary criteria.
Examples of this kind of app obviously include many kind 1 clients, as well as clients that attempt to bring the benefits of the nostr protocol and network to new use cases - whether long form content, video, image posts, music, emojis, recipes, project management, or any other "content type".
To drill down into one example, let's think for a moment about forms. What's so great about a forms app that is built on nostr? Well,
- There is a spec for forms and responses, which means that...
- Multiple clients can implement the same data format, allowing for credible exit and user choice, even of...
- Other products not focused on forms, which can still view, respond to, or embed forms, and which can send their users via NIP 89 to a client that does...
- Cryptographically sign forms and responses, which means they are self-authenticating and can be sent to...
- Multiple relays, which reduces the amount of trust necessary to be confident results haven't been deliberately "lost".
Show me a forms product that does all of those things, and isn't built on nostr. You can't, because it doesn't exist. Meanwhile, there are plenty of image hosts with APIs, streaming services, and bitcoin wallets which have basically the same levels of censorship resistance, interoperability, and network effect as if they weren't built on nostr.
It supports nostr
Notice I haven't said anything about whether relays, signers, blossom servers, software libraries, DVMs, and the accumulated addenda of the nostr ecosystem are nostr apps. Well, they are (usually).
This is the category of nostr app that gets none of the credit for doing all of the work. There's no question that they qualify as beautiful nostrcorns, because their value propositions are entirely meaningless outside of the context of nostr. Who needs a signer if you don't have a cryptographic identity you need to protect? DVMs are literally impossible to use without relays. How are you going to find the blossom server that will serve a given hash if you don't know which servers the publishing user has selected to store their content?
In addition to being entirely contextualized by nostr architecture, this type of nostr app is valuable because it does things "the nostr way". By that I mean that they don't simply try to replicate existing internet functionality into a nostr context; instead, they create entirely new ways of putting the basic building blocks of the internet back together.
A great example of this is how Nostr Connect, Nostr Wallet Connect, and DVMs all use relays as brokers, which allows service providers to avoid having to accept incoming network connections. This opens up really interesting possibilities all on its own.
So while I might hesitate to call many of these things "apps", they are certainly "nostr".
Appendix: it smells like a NINO
So, let's say you've created an app, but when you show it to people they politely smile, nod, and call it a NINO (Nostr In Name Only). What's a hacker to do? Well, here's your handy-dandy guide on how to wash that NINO stench off and Become a Nostr.
You app might be a NINO if:
- There's no NIP for your data format (or you're abusing NIP 78, 32, etc by inventing a sub-protocol inside an existing event kind)
- There's a NIP, but no one knows about it because it's in a text file on your hard drive (or buried in your project's repository)
- Your NIP imposes an incompatible/centralized/legacy web paradigm onto nostr
- Your NIP relies on trusted third (or first) parties
- There's only one implementation of your NIP (yours)
- Your core value proposition doesn't depend on relays, events, or nostr identities
- One or more relay urls are hard-coded into the source code
- Your app depends on a specific relay implementation to work (ahem, relay29)
- You don't validate event signatures
- You don't publish events to relays you don't control
- You don't read events from relays you don't control
- You use legacy web services to solve problems, rather than nostr-native solutions
- You use nostr-native solutions, but you've hardcoded their pubkeys or URLs into your app
- You don't use NIP 89 to discover clients and services
- You haven't published a NIP 89 listing for your app
- You don't leverage your users' web of trust for filtering out spam
- You don't respect your users' mute lists
- You try to "own" your users' data
Now let me just re-iterate - it's ok to be a NINO. We need NINOs, because nostr can't (and shouldn't) tackle every problem. You just need to decide whether your app, as a NINO, is actually contributing to the nostr ecosystem, or whether you're just using buzzwords to whitewash a legacy web software product.
If you're in the former camp, great! If you're in the latter, what are you waiting for? Only you can fix your NINO problem. And there are lots of ways to do this, depending on your own unique situation:
- Drop nostr support if it's not doing anyone any good. If you want to build a normal company and make some money, that's perfectly fine.
- Build out your nostr integration - start taking advantage of webs of trust, self-authenticating data, event handlers, etc.
- Work around the problem. Think you need a special relay feature for your app to work? Guess again. Consider encryption, AUTH, DVMs, or better data formats.
- Think your idea is a good one? Talk to other devs or open a PR to the nips repo. No one can adopt your NIP if they don't know about it.
- Keep going. It can sometimes be hard to distinguish a research project from a NINO. New ideas have to be built out before they can be fully appreciated.
- Listen to advice. Nostr developers are friendly and happy to help. If you're not sure why you're getting traction, ask!
I sincerely hope this article is useful for all of you out there in NINO land. Maybe this made you feel better about not passing the totally optional nostr app purity test. Or maybe it gave you some actionable next steps towards making a great NINON (Nostr In Not Only Name) app. In either case, GM and PV.

2024-10-26 22:14:19The future of physical money is at stake, and the discussion about DREX, the new digital currency planned by the Central Bank of Brazil, is gaining momentum. In a candid and intense conversation, Federal Deputy Julia Zanatta (PL/SC) discussed the challenges and risks of this digital transition, also addressing her Bill No. 3,341/2024, which aims to prevent the extinction of physical currency. This bill emerges as a direct response to legislative initiatives seeking to replace physical money with digital alternatives, limiting citizens' options and potentially compromising individual freedom. Let's delve into the main points of this conversation.
https://www.fountain.fm/episode/i5YGJ9Ors3PkqAIMvNQ0
What is a CBDC?
Before discussing the specifics of DREX, it’s important to understand what a CBDC (Central Bank Digital Currency) is. CBDCs are digital currencies issued by central banks, similar to a digital version of physical money. Unlike cryptocurrencies such as Bitcoin, which operate in a decentralized manner, CBDCs are centralized and regulated by the government. In other words, they are digital currencies created and controlled by the Central Bank, intended to replace physical currency.
A prominent feature of CBDCs is their programmability. This means that the government can theoretically set rules about how, where, and for what this currency can be used. This aspect enables a level of control over citizens' finances that is impossible with physical money. By programming the currency, the government could limit transactions by setting geographical or usage restrictions. In practice, money within a CBDC could be restricted to specific spending or authorized for use in a defined geographical area.
In countries like China, where citizen actions and attitudes are also monitored, a person considered to have a "low score" due to a moral or ideological violation may have their transactions limited to essential purchases, restricting their digital currency use to non-essential activities. This financial control is strengthened because, unlike physical money, digital currency cannot be exchanged anonymously.
Practical Example: The Case of DREX During the Pandemic
To illustrate how DREX could be used, an example was given by Eric Altafim, director of Banco Itaú. He suggested that, if DREX had existed during the COVID-19 pandemic, the government could have restricted the currency’s use to a 5-kilometer radius around a person’s residence, limiting their economic mobility. Another proposed use by the executive related to the Bolsa Família welfare program: the government could set up programming that only allows this benefit to be used exclusively for food purchases. Although these examples are presented as control measures for safety or organization, they demonstrate how much a CBDC could restrict citizens' freedom of choice.
To illustrate the potential for state control through a Central Bank Digital Currency (CBDC), such as DREX, it is helpful to look at the example of China. In China, the implementation of a CBDC coincides with the country’s Social Credit System, a governmental surveillance tool that assesses citizens' and companies' behavior. Together, these technologies allow the Chinese government to monitor, reward, and, above all, punish behavior deemed inappropriate or threatening to the government.
How Does China's Social Credit System Work?
Implemented in 2014, China's Social Credit System assigns every citizen and company a "score" based on various factors, including financial behavior, criminal record, social interactions, and even online activities. This score determines the benefits or penalties each individual receives and can affect everything from public transport access to obtaining loans and enrolling in elite schools for their children. Citizens with low scores may face various sanctions, including travel restrictions, fines, and difficulty in securing loans.
With the adoption of the CBDC — or “digital yuan” — the Chinese government now has a new tool to closely monitor citizens' financial transactions, facilitating the application of Social Credit System penalties. China’s CBDC is a programmable digital currency, which means that the government can restrict how, when, and where the money can be spent. Through this level of control, digital currency becomes a powerful mechanism for influencing citizens' behavior.
Imagine, for instance, a citizen who repeatedly posts critical remarks about the government on social media or participates in protests. If the Social Credit System assigns this citizen a low score, the Chinese government could, through the CBDC, restrict their money usage in certain areas or sectors. For example, they could be prevented from buying tickets to travel to other regions, prohibited from purchasing certain consumer goods, or even restricted to making transactions only at stores near their home.
Another example of how the government can use the CBDC to enforce the Social Credit System is by monitoring purchases of products such as alcohol or luxury items. If a citizen uses the CBDC to spend more than the government deems reasonable on such products, this could negatively impact their social score, resulting in additional penalties such as future purchase restrictions or a lowered rating that impacts their personal and professional lives.
In China, this kind of control has already been demonstrated in several cases. Citizens added to Social Credit System “blacklists” have seen their spending and investment capacity severely limited. The combination of digital currency and social scores thus creates a sophisticated and invasive surveillance system, through which the Chinese government controls important aspects of citizens’ financial lives and individual freedoms.
Deputy Julia Zanatta views these examples with great concern. She argues that if the state has full control over digital money, citizens will be exposed to a level of economic control and surveillance never seen before. In a democracy, this control poses a risk, but in an authoritarian regime, it could be used as a powerful tool of repression.
DREX and Bill No. 3,341/2024
Julia Zanatta became aware of a bill by a Workers' Party (PT) deputy (Bill 4068/2020 by Deputy Reginaldo Lopes - PT/MG) that proposes the extinction of physical money within five years, aiming for a complete transition to DREX, the digital currency developed by the Central Bank of Brazil. Concerned about the impact of this measure, Julia drafted her bill, PL No. 3,341/2024, which prohibits the elimination of physical money, ensuring citizens the right to choose physical currency.
“The more I read about DREX, the less I want its implementation,” says the deputy. DREX is a Central Bank Digital Currency (CBDC), similar to other state digital currencies worldwide, but which, according to Julia, carries extreme control risks. She points out that with DREX, the State could closely monitor each citizen’s transactions, eliminating anonymity and potentially restricting freedom of choice. This control would lie in the hands of the Central Bank, which could, in a crisis or government change, “freeze balances or even delete funds directly from user accounts.”
Risks and Individual Freedom
Julia raises concerns about potential abuses of power that complete digitalization could allow. In a democracy, state control over personal finances raises serious questions, and EddieOz warns of an even more problematic future. “Today we are in a democracy, but tomorrow, with a government transition, we don't know if this kind of power will be used properly or abused,” he states. In other words, DREX gives the State the ability to restrict or condition the use of money, opening the door to unprecedented financial surveillance.
EddieOz cites Nigeria as an example, where a CBDC was implemented, and the government imposed severe restrictions on the use of physical money to encourage the use of digital currency, leading to protests and clashes in the country. In practice, the poorest and unbanked — those without regular access to banking services — were harshly affected, as without physical money, many cannot conduct basic transactions. Julia highlights that in Brazil, this situation would be even more severe, given the large number of unbanked individuals and the extent of rural areas where access to technology is limited.
The Relationship Between DREX and Pix
The digital transition has already begun with Pix, which revolutionized instant transfers and payments in Brazil. However, Julia points out that Pix, though popular, is a citizen’s choice, while DREX tends to eliminate that choice. The deputy expresses concern about new rules suggested for Pix, such as daily transaction limits of a thousand reais, justified as anti-fraud measures but which, in her view, represent additional control and a profit opportunity for banks. “How many more rules will banks create to profit from us?” asks Julia, noting that DREX could further enhance control over personal finances.
International Precedents and Resistance to CBDC
The deputy also cites examples from other countries resisting the idea of a centralized digital currency. In the United States, states like New Hampshire have passed laws to prevent the advance of CBDCs, and leaders such as Donald Trump have opposed creating a national digital currency. Trump, addressing the topic, uses a justification similar to Julia’s: in a digitalized system, “with one click, your money could disappear.” She agrees with the warning, emphasizing the control risk that a CBDC represents, especially for countries with disadvantaged populations.
Besides the United States, Canada, Colombia, and Australia have also suspended studies on digital currencies, citing the need for further discussions on population impacts. However, in Brazil, the debate on DREX is still limited, with few parliamentarians and political leaders openly discussing the topic. According to Julia, only she and one or two deputies are truly trying to bring this discussion to the Chamber, making DREX’s advance even more concerning.
Bill No. 3,341/2024 and Popular Pressure
For Julia, her bill is a first step. Although she acknowledges that ideally, it would prevent DREX's implementation entirely, PL 3341/2024 is a measure to ensure citizens' choice to use physical money, preserving a form of individual freedom. “If the future means control, I prefer to live in the past,” Julia asserts, reinforcing that the fight for freedom is at the heart of her bill.
However, the deputy emphasizes that none of this will be possible without popular mobilization. According to her, popular pressure is crucial for other deputies to take notice and support PL 3341. “I am only one deputy, and we need the public’s support to raise the project’s visibility,” she explains, encouraging the public to press other parliamentarians and ask them to “pay attention to PL 3341 and the project that prohibits the end of physical money.” The deputy believes that with a strong awareness and pressure movement, it is possible to advance the debate and ensure Brazilians’ financial freedom.
What’s at Stake?
Julia Zanatta leaves no doubt: DREX represents a profound shift in how money will be used and controlled in Brazil. More than a simple modernization of the financial system, the Central Bank’s CBDC sets precedents for an unprecedented level of citizen surveillance and control in the country. For the deputy, this transition needs to be debated broadly and transparently, and it’s up to the Brazilian people to defend their rights and demand that the National Congress discuss these changes responsibly.
The deputy also emphasizes that, regardless of political or partisan views, this issue affects all Brazilians. “This agenda is something that will affect everyone. We need to be united to ensure people understand the gravity of what could happen.” Julia believes that by sharing information and generating open debate, it is possible to prevent Brazil from following the path of countries that have already implemented a digital currency in an authoritarian way.
A Call to Action
The future of physical money in Brazil is at risk. For those who share Deputy Julia Zanatta’s concerns, the time to act is now. Mobilize, get informed, and press your representatives. PL 3341/2024 is an opportunity to ensure that Brazilian citizens have a choice in how to use their money, without excessive state interference or surveillance.
In the end, as the deputy puts it, the central issue is freedom. “My fear is that this project will pass, and people won’t even understand what is happening.” Therefore, may every citizen at least have the chance to understand what’s at stake and make their voice heard in defense of a Brazil where individual freedom and privacy are respected values.

2025-02-05 05:52:13Basic concept of temperature and humidity sensor Temperature and humidity sensor is a device used to measure ambient temperature and humidity, and is widely used in meteorology, agriculture, industry, warehousing and other fields. It can measure the temperature and humidity in the air through a certain detection device, and then convert it into electrical signals or other required forms of information output according to certain rules to meet user needs.
Definition of temperature and humidity sensor Temperature and humidity sensor refers to a device or device that can convert temperature and humidity into electrical signals that are easy to measure and process. The temperature and humidity sensors on the market generally measure temperature and relative humidity. Temperature is a physical quantity that measures the hotness and coldness of an object, while humidity indicates the amount of moisture contained in the air.
Types of temperature and humidity sensors Digital temperature and humidity sensor: can convert temperature and humidity into electrical signals that are easy to measure and process, which is convenient for computers, Pl Cs, smart meters and other equipment to read directly. Analog temperature and humidity sensor: transmits data through analog signals, suitable for traditional monitoring systems.
Working principle of temperature and humidity sensor The working principle of temperature and humidity sensor mainly relies on the internal humidity sensing element and temperature sensing element to sense, thereby adjusting the display changes. Common principles include:
Metal expansion principle: metal will produce a corresponding extension after the ambient temperature changes, and the sensor can convert the temperature change signal in this way. Bimetallic sensor: It is composed of two pieces of metal with different expansion coefficients. When the temperature changes, the bimetallic strip will bend, thereby triggering the corresponding mechanical or electrical signal output.
Application scenarios of temperature and humidity sensors Industrial field In the industrial field, temperature and humidity sensors are widely used in the fields of temperature measurement and control in the petroleum, chemical, chemical fiber, textile, rubber, building materials, electricity, machinery manufacturing, metallurgy, medicine, food and other industries.

2025-01-01 17:39:51Heute möchte ich ein Gedicht mit euch teilen. Es handelt sich um eine Ballade des österreichischen Lyrikers Johann Gabriel Seidl aus dem 19. Jahrhundert. Mir sind diese Worte fest in Erinnerung, da meine Mutter sie perfekt rezitieren konnte, auch als die Kräfte schon langsam schwanden.
Dem originalen Titel «Die Uhr» habe ich für mich immer das Wort «innere» hinzugefügt. Denn der Zeitmesser – hier vermutliche eine Taschenuhr – symbolisiert zwar in dem Kontext das damalige Zeitempfinden und die Umbrüche durch die industrielle Revolution, sozusagen den Zeitgeist und das moderne Leben. Aber der Autor setzt sich philosophisch mit der Zeit auseinander und gibt seinem Werk auch eine klar spirituelle Dimension.
Das Ticken der Uhr und die Momente des Glücks und der Trauer stehen sinnbildlich für das unaufhaltsame Fortschreiten und die Vergänglichkeit des Lebens. Insofern könnte man bei der Uhr auch an eine Sonnenuhr denken. Der Rhythmus der Ereignisse passt uns vielleicht nicht immer in den Kram.
Was den Takt pocht, ist durchaus auch das Herz, unser «inneres Uhrwerk». Wenn dieses Meisterwerk einmal stillsteht, ist es unweigerlich um uns geschehen. Hoffentlich können wir dann dankbar sagen: «Ich habe mein Bestes gegeben.»
Ich trage, wo ich gehe, stets eine Uhr bei mir; \ Wieviel es geschlagen habe, genau seh ich an ihr. \ Es ist ein großer Meister, der künstlich ihr Werk gefügt, \ Wenngleich ihr Gang nicht immer dem törichten Wunsche genügt.
Ich wollte, sie wäre rascher gegangen an manchem Tag; \ Ich wollte, sie hätte manchmal verzögert den raschen Schlag. \ In meinen Leiden und Freuden, in Sturm und in der Ruh, \ Was immer geschah im Leben, sie pochte den Takt dazu.
Sie schlug am Sarge des Vaters, sie schlug an des Freundes Bahr, \ Sie schlug am Morgen der Liebe, sie schlug am Traualtar. \ Sie schlug an der Wiege des Kindes, sie schlägt, will's Gott, noch oft, \ Wenn bessere Tage kommen, wie meine Seele es hofft.
Und ward sie auch einmal träger, und drohte zu stocken ihr Lauf, \ So zog der Meister immer großmütig sie wieder auf. \ Doch stände sie einmal stille, dann wär's um sie geschehn, \ Kein andrer, als der sie fügte, bringt die Zerstörte zum Gehn.
Dann müßt ich zum Meister wandern, der wohnt am Ende wohl weit, \ Wohl draußen, jenseits der Erde, wohl dort in der Ewigkeit! \ Dann gäb ich sie ihm zurücke mit dankbar kindlichem Flehn: \ Sieh, Herr, ich hab nichts verdorben, sie blieb von selber stehn.
Johann Gabriel Seidl (1804-1875)

2024-12-21 09:54:49Falls du beim Lesen des Titels dieses Newsletters unwillkürlich an positive Neuigkeiten aus dem globalen polit-medialen Irrenhaus oder gar aus dem wirtschaftlichen Umfeld gedacht hast, darf ich dich beglückwünschen. Diese Assoziation ist sehr löblich, denn sie weist dich als unverbesserlichen Optimisten aus. Leider muss ich dich diesbezüglich aber enttäuschen. Es geht hier um ein anderes Thema, allerdings sehr wohl ein positives, wie ich finde.
Heute ist ein ganz besonderer Tag: die Wintersonnenwende. Genau gesagt hat heute morgen um 10:20 Uhr Mitteleuropäischer Zeit (MEZ) auf der Nordhalbkugel unseres Planeten der astronomische Winter begonnen. Was daran so außergewöhnlich ist? Der kürzeste Tag des Jahres war gestern, seit heute werden die Tage bereits wieder länger! Wir werden also jetzt jeden Tag ein wenig mehr Licht haben.
Für mich ist dieses Ereignis immer wieder etwas kurios: Es beginnt der Winter, aber die Tage werden länger. Das erscheint mir zunächst wie ein Widerspruch, denn meine spontanen Assoziationen zum Winter sind doch eher Kälte und Dunkelheit, relativ zumindest. Umso erfreulicher ist der emotionale Effekt, wenn dann langsam die Erkenntnis durchsickert: Ab jetzt wird es schon wieder heller!
Natürlich ist es kalt im Winter, mancherorts mehr als anderswo. Vielleicht jedoch nicht mehr lange, wenn man den Klimahysterikern glauben wollte. Mindestens letztes Jahr hat Väterchen Frost allerdings gleich zu Beginn seiner Saison – und passenderweise während des globalen Überhitzungsgipfels in Dubai – nochmal richtig mit der Faust auf den Tisch gehauen. Schnee- und Eischaos sind ja eigentlich in der Agenda bereits nicht mehr vorgesehen. Deswegen war man in Deutschland vermutlich in vorauseilendem Gehorsam schon nicht mehr darauf vorbereitet und wurde glatt lahmgelegt.
Aber ich schweife ab. Die Aussicht auf nach und nach mehr Licht und damit auch Wärme stimmt mich froh. Den Zusammenhang zwischen beidem merkt man in Andalusien sehr deutlich. Hier, wo die Häuser im Winter arg auskühlen, geht man zum Aufwärmen raus auf die Straße oder auf den Balkon. Die Sonne hat auch im Winter eine erfreuliche Kraft. Und da ist jede Minute Gold wert.
Außerdem ist mir vor Jahren so richtig klar geworden, warum mir das südliche Klima so sehr gefällt. Das liegt nämlich nicht nur an der Sonne als solcher, oder der Wärme – das liegt vor allem am Licht. Ohne Licht keine Farben, das ist der ebenso simple wie gewaltige Unterschied zwischen einem deprimierenden matschgraubraunen Winter und einem fröhlichen bunten. Ein großes Stück Lebensqualität.
Mir gefällt aber auch die Symbolik dieses Tages: Licht aus der Dunkelheit, ein Wendepunkt, ein Neuanfang, neue Möglichkeiten, Übergang zu neuer Aktivität. In der winterlichen Stille keimt bereits neue Lebendigkeit. Und zwar in einem Zyklus, das wird immer wieder so geschehen. Ich nehme das gern als ein Stück Motivation, es macht mir Hoffnung und gibt mir Energie.
Übrigens ist parallel am heutigen Tag auf der südlichen Halbkugel Sommeranfang. Genau im entgegengesetzten Rhythmus, sich ergänzend, wie Yin und Yang. Das alles liegt an der Schrägstellung der Erdachse, die ist nämlich um 23,4º zur Umlaufbahn um die Sonne geneigt. Wir erinnern uns, gell?
Insofern bleibt eindeutig festzuhalten, dass “schräg sein” ein willkommener, wichtiger und positiver Wert ist. Mit anderen Worten: auch ungewöhnlich, eigenartig, untypisch, wunderlich, kauzig, … ja sogar irre, spinnert oder gar “quer” ist in Ordnung. Das schließt das Denken mit ein.
In diesem Sinne wünsche ich euch allen urige Weihnachtstage!
Dieser Beitrag ist letztes Jahr in meiner Denkbar erschienen.

What Is Chat Control?
"Chat Control" refers to a set of proposed measures by the European Union aimed at monitoring and scanning private communications on messaging platforms. The primary goal is to detect and prevent the spread of illegal content, such as child sexual abuse material (CSAM) and to combat terrorism. While the intention is to enhance security and protect vulnerable populations, these proposals have raised significant privacy concerns.
At its core, Chat Control would require messaging services to implement automated scanning technologies that can analyze the content of messages—even those that are end-to-end encrypted. This means that the private messages you send to friends, family, or colleagues could be subject to inspection by algorithms designed to detect prohibited content.
Origins of the Proposal
The initiative for Chat Control emerged from the EU's desire to strengthen its digital security infrastructure. High-profile cases of online abuse and the use of encrypted platforms by criminal organizations have prompted lawmakers to consider more invasive surveillance tactics. The European Commission has been exploring legislation that would make it mandatory for service providers to monitor communications on their platforms.
How Messaging Services Work
Most modern messaging apps, like Signal, Session, SimpleX, Veilid, Protonmail and Tutanota (among others), use end-to-end encryption (E2EE). This encryption ensures that only the sender and the recipient can read the messages being exchanged. Not even the service providers can access the content. This level of security is crucial for maintaining privacy in digital communications, protecting users from hackers, identity thieves, and other malicious actors.
Key Elements of Chat Control
- Automated Content Scanning: Service providers would use algorithms to scan messages for illegal content.
- Circumvention of Encryption: To scan encrypted messages, providers might need to alter their encryption methods, potentially weakening security.
- Mandatory Reporting: If illegal content is detected, providers would be required to report it to authorities.
- Broad Applicability: The measures could apply to all messaging services operating within the EU, affecting both European companies and international platforms.
Why It Matters
Understanding Chat Control is essential because it represents a significant shift in how digital privacy is handled. While combating illegal activities online is crucial, the methods proposed could set a precedent for mass surveillance and the erosion of privacy rights. Everyday users who rely on encrypted messaging for personal and professional communication might find their conversations are no longer as private as they once thought.
Why Is the EU Pushing for Chat Control?
The European Union's push for Chat Control stems from a pressing concern to protect its citizens, particularly children, from online exploitation and criminal activities. With the digital landscape becoming increasingly integral to daily life, the EU aims to strengthen its ability to combat serious crimes facilitated through online platforms.
Protecting Children and Preventing Crime
One of the primary motivations behind Chat Control is the prevention of child sexual abuse material (CSAM) circulating on the internet. Law enforcement agencies have reported a significant increase in the sharing of illegal content through private messaging services. By implementing Chat Control, the EU believes it can more effectively identify and stop perpetrators, rescue victims, and deter future crimes.
Terrorism is another critical concern. Encrypted messaging apps can be used by terrorist groups to plan and coordinate attacks without detection. The EU argues that accessing these communications could be vital in preventing such threats and ensuring public safety.
Legal Context and Legislative Drivers
The push for Chat Control is rooted in several legislative initiatives:
-
ePrivacy Directive: This directive regulates the processing of personal data and the protection of privacy in electronic communications. The EU is considering amendments that would allow for the scanning of private messages under specific circumstances.
-
Temporary Derogation: In 2021, the EU adopted a temporary regulation permitting voluntary detection of CSAM by communication services. The current proposals aim to make such measures mandatory and more comprehensive.
-
Regulation Proposals: The European Commission has proposed regulations that would require service providers to detect, report, and remove illegal content proactively. This would include the use of technologies to scan private communications.
Balancing Security and Privacy
EU officials argue that the proposed measures are a necessary response to evolving digital threats. They emphasize the importance of staying ahead of criminals who exploit technology to harm others. By implementing Chat Control, they believe law enforcement can be more effective without entirely dismantling privacy protections.
However, the EU also acknowledges the need to balance security with fundamental rights. The proposals include provisions intended to limit the scope of surveillance, such as:
-
Targeted Scanning: Focusing on specific threats rather than broad, indiscriminate monitoring.
-
Judicial Oversight: Requiring court orders or oversight for accessing private communications.
-
Data Protection Safeguards: Implementing measures to ensure that data collected is handled securely and deleted when no longer needed.
The Urgency Behind the Push
High-profile cases of online abuse and terrorism have heightened the sense of urgency among EU policymakers. Reports of increasing online grooming and the widespread distribution of illegal content have prompted calls for immediate action. The EU posits that without measures like Chat Control, these problems will continue to escalate unchecked.
Criticism and Controversy
Despite the stated intentions, the push for Chat Control has been met with significant criticism. Opponents argue that the measures could be ineffective against savvy criminals who can find alternative ways to communicate. There is also concern that such surveillance could be misused or extended beyond its original purpose.
The Privacy Concerns and Risks
While the intentions behind Chat Control focus on enhancing security and protecting vulnerable groups, the proposed measures raise significant privacy concerns. Critics argue that implementing such surveillance could infringe on fundamental rights and set a dangerous precedent for mass monitoring of private communications.
Infringement on Privacy Rights
At the heart of the debate is the right to privacy. By scanning private messages, even with automated tools, the confidentiality of personal communications is compromised. Users may no longer feel secure sharing sensitive information, fearing that their messages could be intercepted or misinterpreted by algorithms.
Erosion of End-to-End Encryption
End-to-end encryption (E2EE) is a cornerstone of digital security, ensuring that only the sender and recipient can read the messages exchanged. Chat Control could necessitate the introduction of "backdoors" or weaken encryption protocols, making it easier for unauthorized parties to access private data. This not only affects individual privacy but also exposes communications to potential cyber threats.
Concerns from Privacy Advocates
Organizations like Signal and Tutanota, which offer encrypted messaging services, have voiced strong opposition to Chat Control. They warn that undermining encryption could have far-reaching consequences:
- Security Risks: Weakening encryption makes systems more vulnerable to hacking, espionage, and cybercrime.
- Global Implications: Changes in EU regulations could influence policies worldwide, leading to a broader erosion of digital privacy.
- Ineffectiveness Against Crime: Determined criminals might resort to other, less detectable means of communication, rendering the measures ineffective while still compromising the privacy of law-abiding citizens.
Potential for Government Overreach
There is a fear that Chat Control could lead to increased surveillance beyond its original scope. Once the infrastructure for scanning private messages is in place, it could be repurposed or expanded to monitor other types of content, stifling free expression and dissent.
Real-World Implications for Users
- False Positives: Automated scanning technologies are not infallible and could mistakenly flag innocent content, leading to unwarranted scrutiny or legal consequences for users.
- Chilling Effect: Knowing that messages could be monitored might discourage people from expressing themselves freely, impacting personal relationships and societal discourse.
- Data Misuse: Collected data could be vulnerable to leaks or misuse, compromising personal and sensitive information.
Legal and Ethical Concerns
Privacy advocates also highlight potential conflicts with existing laws and ethical standards:
- Violation of Fundamental Rights: The European Convention on Human Rights and other international agreements protect the right to privacy and freedom of expression.
- Questionable Effectiveness: The ethical justification for such invasive measures is challenged if they do not significantly improve safety or if they disproportionately impact innocent users.
Opposition from Member States and Organizations
Countries like Germany and organizations such as the European Digital Rights (EDRi) have expressed opposition to Chat Control. They emphasize the need to protect digital privacy and caution against hasty legislation that could have unintended consequences.
The Technical Debate: Encryption and Backdoors
The discussion around Chat Control inevitably leads to a complex technical debate centered on encryption and the potential introduction of backdoors into secure communication systems. Understanding these concepts is crucial to grasping the full implications of the proposed measures.
What Is End-to-End Encryption (E2EE)?
End-to-end encryption is a method of secure communication that prevents third parties from accessing data while it's transferred from one end system to another. In simpler terms, only the sender and the recipient can read the messages. Even the service providers operating the messaging platforms cannot decrypt the content.
- Security Assurance: E2EE ensures that sensitive information—be it personal messages, financial details, or confidential business communications—remains private.
- Widespread Use: Popular messaging apps like Signal, Session, SimpleX, Veilid, Protonmail and Tutanota (among others) rely on E2EE to protect user data.
How Chat Control Affects Encryption
Implementing Chat Control as proposed would require messaging services to scan the content of messages for illegal material. To do this on encrypted platforms, providers might have to:
- Introduce Backdoors: Create a means for third parties (including the service provider or authorities) to access encrypted messages.
- Client-Side Scanning: Install software on users' devices that scans messages before they are encrypted and sent, effectively bypassing E2EE.
The Risks of Weakening Encryption
1. Compromised Security for All Users
Introducing backdoors or client-side scanning tools can create vulnerabilities:
- Exploitable Gaps: If a backdoor exists, malicious actors might find and exploit it, leading to data breaches.
- Universal Impact: Weakening encryption doesn't just affect targeted individuals; it potentially exposes all users to increased risk.
2. Undermining Trust in Digital Services
- User Confidence: Knowing that private communications could be accessed might deter people from using digital services or push them toward unregulated platforms.
- Business Implications: Companies relying on secure communications might face increased risks, affecting economic activities.
3. Ineffectiveness Against Skilled Adversaries
- Alternative Methods: Criminals might shift to other encrypted channels or develop new ways to avoid detection.
- False Sense of Security: Weakening encryption could give the impression of increased safety while adversaries adapt and continue their activities undetected.
Signal’s Response and Stance
Signal, a leading encrypted messaging service, has been vocal in its opposition to the EU's proposals:
- Refusal to Weaken Encryption: Signal's CEO Meredith Whittaker has stated that the company would rather cease operations in the EU than compromise its encryption standards.
- Advocacy for Privacy: Signal emphasizes that strong encryption is essential for protecting human rights and freedoms in the digital age.
Understanding Backdoors
A "backdoor" in encryption is an intentional weakness inserted into a system to allow authorized access to encrypted data. While intended for legitimate use by authorities, backdoors pose several problems:
- Security Vulnerabilities: They can be discovered and exploited by unauthorized parties, including hackers and foreign governments.
- Ethical Concerns: The existence of backdoors raises questions about consent and the extent to which governments should be able to access private communications.
The Slippery Slope Argument
Privacy advocates warn that introducing backdoors or mandatory scanning sets a precedent:
- Expanded Surveillance: Once in place, these measures could be extended to monitor other types of content beyond the original scope.

2025-01-26 22:51:16When I first heard about the DOGE project, I was ready to throw my laptop out the window. The initial proposal read like a Silicon Valley libertarian fever dream - taking Musk's chaotic "move fast and break democracy" Twitter approach and unleashing it on federal agencies. Great, I thought, just what we need: more tech bros thinking they can "optimize" public institutions into oblivion.
But here's the weird thing - when you actually dig into what DOGE has morphed into, it's basically just USDS with a meme-worthy rebrand. For those not deep in the civic tech weeds, USDS was Obama's attempt to drag government technology out of the 1990s, inspired by the UK's actually-functional GDS program. And let's be real - government tech procurement is an absolute dumpster fire right now. We're talking billions wasted on projects that would make a CS101 student cringe, while the average American has to navigate websites that look like they were designed on GeoCities.
The deeply ironic thing is that Musk - for all his cosplaying as a technocratic messiah following in his grandfather's footsteps of dreaming up an antidemocratic technocratic state - actually has some relevant experience here. SpaceX did figure out how to work with government contracts without producing $500 million paperweights, and Tesla somehow gamed clean vehicle incentives into birthing the first new major car company since we invented radio.
Look, I'm the first to roll my eyes at Musk's wannabe-fascist posting sprees and his perpetual "I'm the main character of capitalism" energy. But speaking as someone who's banged their head against the wall of government technology modernization for years - if he actually focuses on the tech and keeps his brainrot political takes to himself, maybe DOGE could do some good?
Even Jen Pahlka, who basically wrote the book on government digital services, is cautiously optimistic. The services Americans get from their government are objectively terrible, and the procurement system is trapped in an infinite loop of failure. Maybe - and I can't believe I'm typing this - Musk's particular flavor of disruptive tech deployment could help?
Just... please, for the love of all things agile, let's keep him focused on the actual technology and far away from any more attempts to recreate his grandfather's dreams of a technocratic dystopia. We've got enough of those already.

2024-12-13 19:30:32Das Betriebsklima ist das einzige Klima, \ das du selbst bestimmen kannst. \ Anonym
Eine Strategie zur Anpassung an den Klimawandel hat das deutsche Bundeskabinett diese Woche beschlossen. Da «Wetterextreme wie die immer häufiger auftretenden Hitzewellen und Starkregenereignisse» oft desaströse Auswirkungen auf Mensch und Umwelt hätten, werde eine Anpassung an die Folgen des Klimawandels immer wichtiger. «Klimaanpassungsstrategie» nennt die Regierung das.
Für die «Vorsorge vor Klimafolgen» habe man nun erstmals klare Ziele und messbare Kennzahlen festgelegt. So sei der Erfolg überprüfbar, und das solle zu einer schnelleren Bewältigung der Folgen führen. Dass sich hinter dem Begriff Klimafolgen nicht Folgen des Klimas, sondern wohl «Folgen der globalen Erwärmung» verbergen, erklärt den Interessierten die Wikipedia. Dabei ist das mit der Erwärmung ja bekanntermaßen so eine Sache.
Die Zunahme schwerer Unwetterereignisse habe gezeigt, so das Ministerium, wie wichtig eine frühzeitige und effektive Warnung der Bevölkerung sei. Daher solle es eine deutliche Anhebung der Nutzerzahlen der sogenannten Nina-Warn-App geben.
Die ARD spurt wie gewohnt und setzt die Botschaft zielsicher um. Der Artikel beginnt folgendermaßen:
«Die Flut im Ahrtal war ein Schock für das ganze Land. Um künftig besser gegen Extremwetter gewappnet zu sein, hat die Bundesregierung eine neue Strategie zur Klimaanpassung beschlossen. Die Warn-App Nina spielt eine zentrale Rolle. Der Bund will die Menschen in Deutschland besser vor Extremwetter-Ereignissen warnen und dafür die Reichweite der Warn-App Nina deutlich erhöhen.»
Die Kommunen würden bei ihren «Klimaanpassungsmaßnahmen» vom Zentrum KlimaAnpassung unterstützt, schreibt das Umweltministerium. Mit dessen Aufbau wurden das Deutsche Institut für Urbanistik gGmbH, welches sich stark für Smart City-Projekte engagiert, und die Adelphi Consult GmbH beauftragt.
Adelphi beschreibt sich selbst als «Europas führender Think-and-Do-Tank und eine unabhängige Beratung für Klima, Umwelt und Entwicklung». Sie seien «global vernetzte Strateg*innen und weltverbessernde Berater*innen» und als «Vorreiter der sozial-ökologischen Transformation» sei man mit dem Deutschen Nachhaltigkeitspreis ausgezeichnet worden, welcher sich an den Zielen der Agenda 2030 orientiere.
Über die Warn-App mit dem niedlichen Namen Nina, die möglichst jeder auf seinem Smartphone installieren soll, informiert das Bundesamt für Bevölkerungsschutz und Katastrophenhilfe (BBK). Gewarnt wird nicht nur vor Extrem-Wetterereignissen, sondern zum Beispiel auch vor Waffengewalt und Angriffen, Strom- und anderen Versorgungsausfällen oder Krankheitserregern. Wenn man die Kategorie Gefahreninformation wählt, erhält man eine Dosis von ungefähr zwei Benachrichtigungen pro Woche.
Beim BBK erfahren wir auch einiges über die empfohlenen Systemeinstellungen für Nina. Der Benutzer möge zum Beispiel den Zugriff auf die Standortdaten «immer zulassen», und zwar mit aktivierter Funktion «genauen Standort verwenden». Die Datennutzung solle unbeschränkt sein, auch im Hintergrund. Außerdem sei die uneingeschränkte Akkunutzung zu aktivieren, der Energiesparmodus auszuschalten und das Stoppen der App-Aktivität bei Nichtnutzung zu unterbinden.
Dass man so dramatische Ereignisse wie damals im Ahrtal auch anders bewerten kann als Regierungen und Systemmedien, hat meine Kollegin Wiltrud Schwetje anhand der Tragödie im spanischen Valencia gezeigt. Das Stichwort «Agenda 2030» taucht dabei in einem Kontext auf, der wenig mit Nachhaltigkeitspreisen zu tun hat.

2025-02-03 02:19:03At-Risk Groups Are Facing A Battle For Their Rights
Privacy. It’s a word we often take for granted, scrolling through our phones and sharing photos without a second thought. But for certain groups—those at risk due to their identities, beliefs, or circumstances—privacy isn’t just a luxury; it’s a lifeline. In today’s world, where governments, corporations, and even our own social media accounts seem to have a vested interest in collecting and selling our data, the fight for privacy has never been more crucial.
Privacy is not a buzzword but a fundamental human right. We can do more to protect those who need it most.
Privacy As A Human Right
The concept of privacy is deeply rooted in our basic human rights. It’s not just about keeping your medical records confidential or hiding your bank statements; it’s about the right to control what others can know about you. For individuals who identify as LGBTQ+, immigrants, journalists, or political dissidents, this right is even more fragile.
Recently, we’ve seen a rise in policies that seem designed to strip away these protections. From the Trump administration’s transgender ban on military service and passport changes to the targeting of journalists and activists, the message is clear: certain groups are considered fair game for scrutiny and control.
These actions are about erasing the autonomy of individuals to live their lives without fear of retribution or discrimination. Privacy isn’t just a feel-good concept; it’s the cornerstone of a individuals liberty. We must ensure that no one’s rights can be arbitrarily taken away, especially the right to privacy.
The Attack On Vulnerable Groups
The targeting of at-risk groups has reached a fever pitch in recent months:
- Transgender Rights Under Fire
The Trump administration has issued a sweeping executive order that effectively erased recognition of transgender individuals’ rights. This included changes to passport policies that required individuals to declare their gender at birth, making it nearly impossible for trans individuals to update their documents without facing extreme scrutiny or even denial.
These actions don’t just impact transgender people; they send a chilling message to the entire LGBTQ+ community.
- Free Speech And Political Dissent
Trump’s Free Speech Executive Order, aimed to protect citizens’ right to express their beliefs. However, critics argue it was more about silencing dissenters. Journalists, activists, and even private citizens have faced increasing pressure from government officials to either comply with certain views or face professional consequences.
“Free speech is a double-edged sword,” noted one legal expert. “When the government uses it as a tool to marginalize certain groups, it becomes a weapon rather than a shield.”
-
Media And Press Freedom
Trump’s ongoing battles with major media outlets are well-documented. From labeling reporters as “fake news” to pushing for laws that would limit press freedom, the administration has made it clear that journalists and news organizations are not above scrutiny. For independent journalists and investigative reporters, this poses a significant threat to their work and safety. -
Immigrant Rights And Discrimination
The Trump administration’s harsh immigration policies have had a devastating impact on vulnerable communities. From family separations to the expansion of surveillance in immigrant-heavy areas, these actions have left many feeling exposed and unsafe. Immigrants, particularly those from Latin America and the Middle East, are increasingly targeted for their perceived alignments with political rhetoric.
The Consequences Of Losing Privacy
When privacy is stripped away, it doesn’t just affect individuals—it affects entire communities. For transgender individuals, the fear of being “outted” online or facing discrimination at work is a daily reality. For journalists, the threat of government retribution can lead to self-censorship and an inability to hold power accountable. For immigrants, the risk of deportation or surveillance means constant vigilance—and often, no recourse.
These consequences are not just personal; they’re systemic. When certain groups are deemed unworthy of protection, it sets a dangerous precedent for what’s allowed in society. It sends the message that some lives matter less than others, and that the government can act with impunity. If you are not in one of these currently impacted groups just give it time and eventually they will come for you too.
The Fight For Privacy: What We Can Do
The good news is that we don’t have to sit idly by while this happens. There are steps we can take to fight for privacy as a fundamental right. Here’s how:
-
Advocate For Stronger Protections
Governments at all levels need to pass and enforce laws that protect privacy, especially for vulnerable groups. This includes everything from data protection legislation to anti-discrimination policies. -
Support Independent Journalism
Journalists are on the front lines of this fight, uncovering corruption and holding power accountable. Support independent media outlets and platforms that prioritize transparency and press freedom. -
Educate And Empower
Communities under threat need resources to protect themselves. This includes education on their rights, know how and tools to secure their data, and access to legal support when needed. -
Use Your Voice
Speak out against policies that erode privacy and target vulnerable groups. Use your actions to protect yourself and others. -
Demand Accountability
When governments overreach, they need to be held accountable. Fight for yours and others rights.
Privacy Is A Fight Worth Winning
Privacy isn’t just about convenience or comfort—it’s about freedom, autonomy, and the right to live without fear of arbitrary control. For at-risk groups, this is not just a luxury; it’s a lifeline. As we move forward in this uncertain era, let’s remember that the fight for privacy is not over— it’s just beginning.
We all have a role to play in protecting those who need it most. So let’s get to work.

2024-12-06 18:21:15Die Ungerechtigkeit ist uns nur in dem Falle angenehm,\ dass wir Vorteile aus ihr ziehen;\ in jedem andern hegt man den Wunsch,\ dass der Unschuldige in Schutz genommen werde.\ Jean-Jacques Rousseau
Politiker beteuern jederzeit, nur das Beste für die Bevölkerung zu wollen – nicht von ihr. Auch die zahlreichen unsäglichen «Corona-Maßnahmen» waren angeblich zu unserem Schutz notwendig, vor allem wegen der «besonders vulnerablen Personen». Daher mussten alle möglichen Restriktionen zwangsweise und unter Umgehung der Parlamente verordnet werden.
Inzwischen hat sich immer deutlicher herausgestellt, dass viele jener «Schutzmaßnahmen» den gegenteiligen Effekt hatten, sie haben den Menschen und den Gesellschaften enorm geschadet. Nicht nur haben die experimentellen Geninjektionen – wie erwartet – massive Nebenwirkungen, sondern Maskentragen schadet der Psyche und der Entwicklung (nicht nur unserer Kinder) und «Lockdowns und Zensur haben Menschen getötet».
Eine der wichtigsten Waffen unserer «Beschützer» ist die Spaltung der Gesellschaft. Die tiefen Gräben, die Politiker, Lobbyisten und Leitmedien praktisch weltweit ausgehoben haben, funktionieren leider nahezu in Perfektion. Von ihren persönlichen Erfahrungen als Kritikerin der Maßnahmen berichtete kürzlich eine Schweizerin im Interview mit Transition News. Sie sei schwer enttäuscht und verspüre bis heute eine Hemmschwelle und ein seltsames Unwohlsein im Umgang mit «Geimpften».
Menschen, die aufrichtig andere schützen wollten, werden von einer eindeutig politischen Justiz verfolgt, verhaftet und angeklagt. Dazu zählen viele Ärzte, darunter Heinrich Habig, Bianca Witzschel und Walter Weber. Über den aktuell laufenden Prozess gegen Dr. Weber hat Transition News mehrfach berichtet (z.B. hier und hier). Auch der Selbstschutz durch Verweigerung der Zwangs-Covid-«Impfung» bewahrt nicht vor dem Knast, wie Bundeswehrsoldaten wie Alexander Bittner erfahren mussten.
Die eigentlich Kriminellen schützen sich derweil erfolgreich selber, nämlich vor der Verantwortung. Die «Impf»-Kampagne war «das größte Verbrechen gegen die Menschheit». Trotzdem stellt man sich in den USA gerade die Frage, ob der scheidende Präsident Joe Biden nach seinem Sohn Hunter möglicherweise auch Anthony Fauci begnadigen wird – in diesem Fall sogar präventiv. Gibt es überhaupt noch einen Rest Glaubwürdigkeit, den Biden verspielen könnte?
Der Gedanke, den ehemaligen wissenschaftlichen Chefberater des US-Präsidenten und Direktor des National Institute of Allergy and Infectious Diseases (NIAID) vorsorglich mit einem Schutzschild zu versehen, dürfte mit der vergangenen Präsidentschaftswahl zu tun haben. Gleich mehrere Personalentscheidungen des designierten Präsidenten Donald Trump lassen Leute wie Fauci erneut in den Fokus rücken.
Das Buch «The Real Anthony Fauci» des nominierten US-Gesundheitsministers Robert F. Kennedy Jr. erschien 2021 und dreht sich um die Machenschaften der Pharma-Lobby in der öffentlichen Gesundheit. Das Vorwort zur rumänischen Ausgabe des Buches schrieb übrigens Călin Georgescu, der Überraschungssieger der ersten Wahlrunde der aktuellen Präsidentschaftswahlen in Rumänien. Vielleicht erklärt diese Verbindung einen Teil der Panik im Wertewesten.
In Rumänien selber gab es gerade einen Paukenschlag: Das bisherige Ergebnis wurde heute durch das Verfassungsgericht annuliert und die für Sonntag angesetzte Stichwahl kurzfristig abgesagt – wegen angeblicher «aggressiver russischer Einmischung». Thomas Oysmüller merkt dazu an, damit sei jetzt in der EU das Tabu gebrochen, Wahlen zu verbieten, bevor sie etwas ändern können.
Unsere Empörung angesichts der Historie von Maßnahmen, die die Falschen beschützen und für die meisten von Nachteil sind, müsste enorm sein. Die Frage ist, was wir damit machen. Wir sollten nach vorne schauen und unsere Energie clever einsetzen. Abgesehen von der Umgehung von jeglichem «Schutz vor Desinformation und Hassrede» (sprich: Zensur) wird es unsere wichtigste Aufgabe sein, Gräben zu überwinden.

2025-02-05 01:48:55(Because Most People Don’t Understand Money)
The requisite knowledge needed to know whether $100 or $100,000 per Bitcoin is relatively speaking “a lot,” is what value means. One way to measure value is through a universal yardstick we call “Money.” The question of “What is money?” is perhaps one of the most overlooked and under answered in our day and age. There is even an entire podcast dedicated to that question with the eponymous title, hosted by Robert Breedlove. That podcast often delves into the more philosophical underpinnings whereas I hope to approach this with a more practical answer.
Money is a technology.
Money is the technology with which we interact with one another to reorganize goods and services to the place and time they are best suited. Most money of the past has been tangible (though not a requisite feature), scarce, recognizable (read: verifiable), durable, portable, and divisible. These features one might call the “Attributes of Money.” These attributes are absolutely essential for a money to maintain its status as a money. (Those of you who understand the U.S. Dollar system maybe scratching your heads right now but, believe me, I will address that elephant in due time.) These attributes, you may notice, are not a yes or no but more of a gradient. A money can be MORE portable than another yet, less durable. One more divisible but not scarce whatsoever. The point being they must have, in some capacity, these attributes or they simply aren’t money.
One of These Things is Not Like the Other
| | Bitcoin | Gold | Dollars | |-----------------|:----------------------------------------------------------------------------------------------------------------:|:------------------------------------------------------------------:|:--------------------------------------------------------------------------------------------------------------------------------------------------:| | Scarcity | 21 million coins
is the maximum supply | Unknown- the
supply grows roughly 2% per year | Also unknown to anyone outside of the Federal Reserve, Trillions and counting | | Recognizability | Each coin is verifiable to it's genesis on the timechain | Each molecule of gold has distinct physical verifiable properties | If the Federal reserve says it is a valid note, it is (Unless you are an enemy of the United States) | | Durablility | Each "Bitcoin" is information stored on a globally distributed network | Doesn't Rust and as far as can be measured Au197 is stable forever | Can be destroyed by any means that effect fabric and centralized databases | | Portability | Available wherever data can be store- Anywhere | Can be moved at 9.81 Newtons per Kilogram- Methods may vary | Can be moved physically with fabric notes- Digitally with express permission from a US accredited banking institution | | Divisibility | Currently can be divided into 100 million parts called Sats (can be further subdivided by adding decimal places) | Can be divided to the Atomic level (Though not practical) | Can be divided (without dilution) by adding new denominative bills or coinage
Can be divided (with dilution) by printing new bills or coinage | | | Bitcoin | Gold | Dollars |You may think with all of the great functionality of Bitcoin that the phrase "One of these things is not like the other" refers to BTC. No, I was referring to the Dollar. It is the only one on the list that was a currency that was substituted as some kind of faux money. It asserts itself, or rather the Federal Reserve asserts it, as money, de facto.
Dollars are NOT money.
Dollars are (allegedly) a currency. If money is a specific technology, currency is the financial infrastructure that allows that technology to reach and be used by the most number of people possible. This requires a firm tether between the asset being used as money and the currency used as a claim to that money. For example: If I hand you a chicken, you have a chicken. But, if I hand you a coupon that is redeemable for a chicken, you do not have a chicken. You have a claim to a chicken that is only as good as the party making that claim. Bringing it back to money again, dollars (Prior to 1971) were redeemable for gold at a rate of $35 per ounce. This is that strong tether that pegged dollars to gold and physical reality itself. Without a proof of work, mining, . Until…
WTF Happened in 1971?
The Nixon shock happened. Briefly, The U.S. took in Europe’s gold in the 1940’s to keep it out of Hitler’s hands. The U.S. made an agreement to peg the dollar to Europe’s gold. The U.S. over printed dollars in relation to the gold holdings. Around 1971 France (among others) called the U.S. out for devaluing the dollar and thus European currencies. So, Nixon “Temporarily” suspended the convertibility of dollars to gold. Now, here we all are like Wile E. Coyote having run off of the golden cliff clutching our dollars in our arms and 54 years later we still haven’t looked down to see the truth.
Dollars Aren’t Backed by Anything
This is why no country in the world today has a money standard. Seemingly they all forgot the number one rule of issuing currency, it must be backed by something. Now, you may hear dollar proponents say “The U.S. dollar is backed by the full faith and credit of the United States!” Another way of saying that is, “We said it is worth something, so it is!” This fiat (by decree) mentality creates a plethora of perverse incentives. The ever growing supply disallows users of the Dollar to save without inccuring the penalties of inflation.
Just a Few Examples of How You're Being Crushed
Because your dollar loses value:
- It pushes people to spend them on assets that seem to appreciate (as the dollar debases) but are truly staying stagnant.
- It pushes people to gamble on securities hoping the perceived value is enough to beat the inflationary curve.
- It pushes people away from saving for their future and the future of their families.
- It creates insane credit incentives so that people borrow way more than they can afford today knowing that dollars will be cheaper in the future. (Effectively a short position)
- It pushes people to spend less and less time making and maintaining their families as it becomes more expensive to keep a similar lifestyle to which it was founded.
These are just a few of the terrible consequences of not knowing that trading a currency with no monetary backing has on a society. Most may blame this soley on the ability to print currency by a central bank but, that is not the only factor. If the fed printed dollars against gold, people would simply take the best rate they could get and remonetize themselves with the gold. But because there is no monetary escape hatch guaranteed by the issuance of dollars, I.E. no one has to take your dollars in exchange for their Bitcoin or gold, you are left at the mercy of the market.
One Day, People Will Stop Accepting Your Dollars
Those lementing the high price of Bitcoin might want to thank their lucky stars that Bitcoin still has a rational number next to the "BTC 1=$?" sign. One day you will have to exchange something of actual value to the spender (no longer a seller). Your product, good or service, will be the only thing that anyone might be willing to part with their Bitcoin over. That is what makes a money, the most salable non-consumable good, whose only funtion is to back a financial structure that facilitates trade.
Bitcoin is Capital
Capital is a broad term that can describe anything that confers value or benefit to its owners, such as a factory and its machinery, or the financial assets of a business or an individual. Bitcoin being the latter creates the financial structures from which you build upon. You use capital to hold, transfer, and grow value. You do not do this with cash. Cash is a depreciating asset when you don't use it to gain goods or services for yourself or your business. This misconception around the equivalance between cash and money (financial capital) is what tricks people into believing Dollars are money. And what's worse is that even some of our greatest heroes have done this.
Slay Your Heroes, Within Reason
Unfortunately due to a mixing of verbiage that have very distinct differences, the title: "Bitcoin: A Peer-to-Peer Electronic Cash System" is technically inaccurate. Bitcoin doesn't fit the definition of cash, which is a liquid asset that can be easily converted into its equivalent value. In short, Satoshi misspoke. In reality, owning Bitcoin UTXOs (with private keys) means you already possess the asset, not just a claim to it. When you spend Bitcoin, the recipient receives the actual asset, not a promise of it. When you receive Bitcoin, you have final settlement on that transaction. Fundamentally Bitcoin is not cash, electronic or otherwise.
Bitcoin is Money.

2025-02-02 22:55:32The Secret to Staying Private in the Digital Wild West: A Guide to Using Encryption
You’re scrolling through social media, and suddenly you realize your phone’s been tracking your location and displaying it on your profile for months. You’re not even sure how that happened. Or maybe you’ve noticed that every time you shop online, the item you looked for follows you around with ads wherever you go. Sound familiar? Yeah, welcome to the digital world—where your data is basically a free buffet for anyone who knows how to ask.
But here’s the thing: you don’t have to sit back and take it. Encryption is like the secret weapon that lets you lock up your data and keep those prying eyes out. It’s not just for hackers or spies—it’s for regular people who want to take control of their privacy in a world that’s increasingly looking like a reality show where everyone’s a contestant.
What Is Encryption, and Why Should You Care?
Encryption is like a secure box that only you can open. When you use encryption, your data is scrambled in a way that’s hard for anyone else to read, even if they try. Think of it as putting on a metaphorical cloak that makes your online activity invisible to just about everyone except the people you want to see it.
For example, when you browse the internet, your connection is often not encrypted by default. That’s why websites start with “https” to indicate a secure connection—it’s saying, “Hey, we’re using encryption here!” Without that little green padlock, anyone on the same WiFi could potentially spy on what you’re doing.
So, encryption isn’t just for tech geeks or government agencies. It’s for everyone who wants to protect their data from being sold, stolen, or misused without their consent. And guess what? You’re already using it without realizing it. Every time you use a password-protected account or send an encrypted message, you’re reaping the benefits of encryption.
The Privacy Advantages of Encryption for Regular People
Let’s break down why encryption is your best friend when it comes to privacy:
-
Financial Transactions
When you pay online or use a banking app, encryption keeps your financial info safe from hackers. It ensures that only the banks and businesses you’re dealing with can access your money—no one else can. -
Online Accounts
Your email, social media, and other accounts often use encryption to protect your login details. That’s why you see those little “lock” icons when you’re logging in. Without encryption, someone could potentially intercept your password and gain unauthorized access to your account. -
Data Breaches
Encryption can often prevent data breaches from being useful. Even if hackers manage to steal your information, the encryption makes it unreadable, so the stolen data is basically worthless to the attackers. -
Location Data
If you’re worried about apps tracking your every move, encryption can help limit how much of that data is accessible. Some apps use encryption to protect location data, making it harder for companies to sell your movements without your consent. -
Privacy Protection
Encryption acts as a layer of protection against invasive technologies. For example, some apps use tracking software that follows you around the internet based on your browsing history. With encryption, these trackers can be blocked or limited, giving you more control over what information is collected about you.
How to Use Encryption Like a Pro
Now that you know why encryption is essential for privacy, let’s talk about how to use it effectively:
-
Use Strong Passwords
Encryption works only if your passwords are strong and unique. Don’t reuse passwords from one account to another, and avoid using easily guessable information like “password123” or your birth year. Use a password manager if you need help keeping track of them. -
Enable HTTPS Everywhere
Install browser extensions like HTTPS Everywhere to automatically encrypt your connections to websites that don’t support encryption by default. This ensures that even if you’re not actively thinking about it, your data is still protected. -
Look for the Lock Icon
Whenever you’re on a website or app, look for the lock icon in the URL bar. Make sure it’s encrypted before you input any personal information. -
Use Encrypted Communication Tools
For private conversations, use apps like Signal or SimpleX, which are designed with encryption in mind. These tools ensure that only the sender and recipient can read your messages, keeping them safe from prying eyes. -
Enable Two-Factor Authentication (2FA)
This isn’t exactly encryption, but it’s a close second. 2FA adds an extra layer of security by requiring you to provide two forms of verification—like your password and a code sent to your phone—to access your account. While not encryption itself, it works alongside encryption to keep your accounts secure. -
Use Encrypted Storage and Backup
When storing sensitive files or data, use encrypted cloud storage or external drives. Tools like BitLocker (for Windows) or AES-256 encryption can protect your files from unauthorized access. -
Stay Updated
Encryption technology is always evolving, so it’s important to keep your software and apps updated. Outdated systems are often easy targets for hackers, leaving you vulnerable to attacks.
Final Thoughts: Your Data Is Your Power
In a world where data is a commodity, encryption is your weapon against the invasive tactics of corporations and hackers alike. It empowers you to control what information you share and protects you from having it used against you. So, whether you’re shopping online, using your favorite apps, or just browsing the web, remember that encryption is there to help you stay private and in control of your own data.
And if you ever feel overwhelmed by all the privacy stuff, just remember this: you’re not alone. Millions of people are fighting for stronger privacy protections every day. So, do your part by using encryption wisely—your data and your privacy are worth it. Let’s make sure no one can take that away from you.
Advocating for privacy does not finance itself. If you enjoyed this article, please consider zapping or sending monero

2024-11-29 19:45:43Konsum ist Therapie.
Wolfgang JoopUmweltbewusstes Verhalten und verantwortungsvoller Konsum zeugen durchaus von einer wünschenswerten Einstellung. Ob man deswegen allerdings einen grünen statt eines schwarzen Freitags braucht, darf getrost bezweifelt werden – zumal es sich um manipulatorische Konzepte handelt. Wie in der politischen Landschaft sind auch hier die Etiketten irgendwas zwischen nichtssagend und trügerisch.
Heute ist also wieder mal «Black Friday», falls Sie es noch nicht mitbekommen haben sollten. Eigentlich haben wir ja eher schon eine ganze «Black Week», der dann oft auch noch ein «Cyber Monday» folgt. Die Werbebranche wird nicht müde, immer neue Anlässe zu erfinden oder zu importieren, um uns zum Konsumieren zu bewegen. Und sie ist damit sehr erfolgreich.
Warum fallen wir auf derartige Werbetricks herein und kaufen im Zweifelsfall Dinge oder Mengen, die wir sicher nicht brauchen? Pure Psychologie, würde ich sagen. Rabattschilder triggern etwas in uns, was den Verstand in Stand-by versetzt. Zusätzlich beeinflussen uns alle möglichen emotionalen Reize und animieren uns zum Schnäppchenkauf.
Gedankenlosigkeit und Maßlosigkeit können besonders bei der Ernährung zu ernsten Problemen führen. Erst kürzlich hat mir ein Bekannter nach einer USA-Reise erzählt, dass es dort offenbar nicht unüblich ist, schon zum ausgiebigen Frühstück in einem Restaurant wenigstens einen Liter Cola zu trinken. Gerne auch mehr, um das Gratis-Nachfüllen des Bechers auszunutzen.
Kritik am schwarzen Freitag und dem unnötigen Konsum kommt oft von Umweltschützern. Neben Ressourcenverschwendung, hohem Energieverbrauch und wachsenden Müllbergen durch eine zunehmende Wegwerfmentalität kommt dabei in der Regel auch die «Klimakrise» auf den Tisch.
Die EU-Kommission lancierte 2015 den Begriff «Green Friday» im Kontext der überarbeiteten Rechtsvorschriften zur Kennzeichnung der Energieeffizienz von Elektrogeräten. Sie nutzte die Gelegenheit kurz vor dem damaligen schwarzen Freitag und vor der UN-Klimakonferenz COP21, bei der das Pariser Abkommen unterzeichnet werden sollte.
Heute wird ein grüner Freitag oft im Zusammenhang mit der Forderung nach «nachhaltigem Konsum» benutzt. Derweil ist die Europäische Union schon weit in ihr Geschäftsmodell des «Green New Deal» verstrickt. In ihrer Propaganda zum Klimawandel verspricht sie tatsächlich «Unterstützung der Menschen und Regionen, die von immer häufigeren Extremwetter-Ereignissen betroffen sind». Was wohl die Menschen in der Region um Valencia dazu sagen?
Ganz im Sinne des Great Reset propagierten die Vereinten Nationen seit Ende 2020 eine «grüne Erholung von Covid-19, um den Klimawandel zu verlangsamen». Der UN-Umweltbericht sah in dem Jahr einen Schwerpunkt auf dem Verbraucherverhalten. Änderungen des Konsumverhaltens des Einzelnen könnten dazu beitragen, den Klimaschutz zu stärken, hieß es dort.
Der Begriff «Schwarzer Freitag» wurde in den USA nicht erstmals für Einkäufe nach Thanksgiving verwendet – wie oft angenommen –, sondern für eine Finanzkrise. Jedoch nicht für den Börsencrash von 1929, sondern bereits für den Zusammenbruch des US-Goldmarktes im September 1869. Seitdem mussten die Menschen weltweit so einige schwarze Tage erleben.
Kürzlich sind die britischen Aufsichtsbehörden weiter von ihrer Zurückhaltung nach dem letzten großen Finanzcrash von 2008 abgerückt. Sie haben Regeln für den Bankensektor gelockert, womit sie «verantwortungsvolle Risikobereitschaft» unterstützen wollen. Man würde sicher zu schwarz sehen, wenn man hier ein grünes Wunder befürchten würde.

2025-01-22 23:49:06Since DVMs were introduced to Nostr in July 2023, we've witnessed remarkable growth - over 2.5 million DVM events (Kinds 5000-7000) and counting. Last fall, when Primal added custom feeds (Kind 5300 DVMs), we saw a 10x surge in DVM activity. To handle this growth, I've spent the last few months completely rewriting DVMDash.
The first version of DVMDash, still live at https://dvmdash.live, unfortunately uses full database table scans to compute the metrics. The code was simpler, but the computation ran on the database. This meant the only way to scale the system was to upgrade the database. Using managed databases (like AWS, Azure, Digital Ocean) beyond the lower tiers gets expensive quickly.
The other problem with the first version: it computes metrics globally (well... as global as you can get; there's no true global with Nostr). Global or all-time metrics aren't sustainable with a system that plans to analyze billions of events in the future (a long term goal for DVMDash). Especially metrics like the number of unique DVMs, Kinds, and Users. I spent more time than I care to admit on possible designs, and have settled on these design principles for now:
- Precise accurate metrics will only be computed for the last 30 days of DVM activity.
- At the turn of a new month, we will compute a snapshot of the last month's activity, and a snapshot per DVM and per Kind, and store them in a historical table. This way we can see what any given month in the past looked like from a bird's eye view with metrics like number of job requests, job results, a count of unique DVMs, kinds and users, which DVMs ran jobs on which kinds, etc. The monthly data will all be aggregate.
The goal of the new redesign is to support processing millions of DVM events an hour. Therefore we need to ensure we can horizontally scale the processing as the traffic increases. Horizontal scaling was the primary goal of this new redesign, and early results indicate it's working.
The new architecture for DVMDash uses a redis queue to hold events collected from relays. Then batches of events are pulled off of the queue by dvm event analyzers to compute metrics. Duplicating these analyzers is one way DVMDash can horizontally scale.
To see if increasing the number of dvm event analyzers improves speed, I ran a performance test on Digital Ocean using real DVM events collected from Jan. 1st 2024 to Jan 9th 2025, which includes more than 2.4 million events. The only difference between each run is the number of DVM event analyzers ranging from 1 to 6.
The first graph shows that adding more event analyzers has a significant speed improvement. With only one analyzer it took nearly an hour to process the 2.4 million events. With every added analyzer, there was a noticeable speedup, as can be seen in the graph. With n=6 analyzers, we were able to process all 2.4 million events in about 10 minutes.
When we look at the rate of processing shown in the second graph, we can see that we get up to 300k dvm events processed per minute when n=6, compared to just ~50k events processed when n=1.
While I did test beyond 6 analyzers, I found the sweet spot for the current infrastructure setup to be around 6 analyzers. This provides plenty of headroom above our current processing needs, which typically see less than a million events per month. Even at a million DVM events per day, DVMDash should be able to handle it with n=2 analyzers running. The most important takeaway is that DVMDash can now horizontally scale by adding more analyzers as DVM activity grows in the future.
The code to run these performance tests, either locally or on Digital Ocean (you'd need an API key), is in the dvmdash repo, so anyone can replicate these tests. There's a lot of nuance to scaling that I'm leaving out of this short article, and you can't get away from having to adjust database capacity (especially number of connections). The code for this test can be found in
experiments/test_batch_processing_scaling.py
and the code to produce the graphs is inexperiments/graph_batch_processing_scaling_data.py
. For now this is still in thefull-redesign
branch, soon it will be merged intomain
.The live version of dvmdash doesn't have these performance updates yet, a complete redesign is coming soon, including a new UI.
I've had my head down working on this rewrite, and couldn't move on to add new features until this was done. Thank you to the folks who made github issues, I'll be getting to those soon.
DVMDash is open source, please drop by and give us a feature request, bug report, pull request or star. Thanks to OpenSats for funding this work.

@ a95c6243:d345522c
2024-11-08 20:02:32Und plötzlich weißt du:
Es ist Zeit, etwas Neues zu beginnen
und dem Zauber des Anfangs zu vertrauen.
Meister EckhartSchwarz, rot, gold leuchtet es im Kopf des Newsletters der deutschen Bundesregierung, der mir freitags ins Postfach flattert. Rot, gelb und grün werden daneben sicher noch lange vielzitierte Farben sein, auch wenn diese nie geleuchtet haben. Die Ampel hat sich gerade selber den Stecker gezogen – und hinterlässt einen wirtschaftlichen und gesellschaftlichen Trümmerhaufen.
Mit einem bemerkenswerten Timing hat die deutsche Regierungskoalition am Tag des «Comebacks» von Donald Trump in den USA endlich ihr Scheitern besiegelt. Während der eine seinen Sieg bei den Präsidentschaftswahlen feierte, erwachten die anderen jäh aus ihrer Selbsthypnose rund um Harris-Hype und Trump-Panik – mit teils erschreckenden Auswüchsen. Seit Mittwoch werden die Geschicke Deutschlands nun von einer rot-grünen Minderheitsregierung «geleitet» und man steuert auf Neuwahlen zu.
Das Kindergarten-Gehabe um zwei konkurrierende Wirtschaftsgipfel letzte Woche war bereits bezeichnend. In einem Strategiepapier gestand Finanzminister Lindner außerdem den «Absturz Deutschlands» ein und offenbarte, dass die wirtschaftlichen Probleme teilweise von der Ampel-Politik «vorsätzlich herbeigeführt» worden seien.
Lindner und weitere FDP-Minister wurden also vom Bundeskanzler entlassen. Verkehrs- und Digitalminister Wissing trat flugs aus der FDP aus; deshalb darf er nicht nur im Amt bleiben, sondern hat zusätzlich noch das Justizministerium übernommen. Und mit Jörg Kukies habe Scholz «seinen Lieblingsbock zum Obergärtner», sprich: Finanzminister befördert, meint Norbert Häring.
Es gebe keine Vertrauensbasis für die weitere Zusammenarbeit mit der FDP, hatte der Kanzler erklärt, Lindner habe zu oft sein Vertrauen gebrochen. Am 15. Januar 2025 werde er daher im Bundestag die Vertrauensfrage stellen, was ggf. den Weg für vorgezogene Neuwahlen freimachen würde.
Apropos Vertrauen: Über die Hälfte der Bundesbürger glauben, dass sie ihre Meinung nicht frei sagen können. Das ging erst kürzlich aus dem diesjährigen «Freiheitsindex» hervor, einer Studie, die die Wechselwirkung zwischen Berichterstattung der Medien und subjektivem Freiheitsempfinden der Bürger misst. «Beim Vertrauen in Staat und Medien zerreißt es uns gerade», kommentierte dies der Leiter des Schweizer Unternehmens Media Tenor, das die Untersuchung zusammen mit dem Institut für Demoskopie Allensbach durchführt.
«Die absolute Mehrheit hat absolut die Nase voll», titelte die Bild angesichts des «Ampel-Showdowns». Die Mehrheit wolle Neuwahlen und die Grünen sollten zuerst gehen, lasen wir dort.
Dass «Insolvenzminister» Robert Habeck heute seine Kandidatur für das Kanzleramt verkündet hat, kann nur als Teil der politmedialen Realitätsverweigerung verstanden werden. Wer allerdings denke, schlimmer als in Zeiten der Ampel könne es nicht mehr werden, sei reichlich optimistisch, schrieb Uwe Froschauer bei Manova. Und er kenne Friedrich Merz schlecht, der sich schon jetzt rhetorisch auf seine Rolle als oberster Feldherr Deutschlands vorbereite.
Was also tun? Der Schweizer Verein «Losdemokratie» will eine Volksinitiative lancieren, um die Bestimmung von Parlamentsmitgliedern per Los einzuführen. Das Losverfahren sorge für mehr Demokratie, denn als Alternative zum Wahlverfahren garantiere es eine breitere Beteiligung und repräsentativere Parlamente. Ob das ein Weg ist, sei dahingestellt.
In jedem Fall wird es notwendig sein, unsere Bemühungen um Freiheit und Selbstbestimmung zu verstärken. Mehr Unabhängigkeit von staatlichen und zentralen Institutionen – also die Suche nach dezentralen Lösungsansätzen – gehört dabei sicher zu den Möglichkeiten. Das gilt sowohl für jede/n Einzelne/n als auch für Entitäten wie die alternativen Medien.

2025-02-05 01:02:39About 150,000 blocks ago, I bought burgers for my family with sats at NextBurger in Newport, California. The Orange County Bitcoin Meetup found a hamburger stand that wanted to accept Bitcoin. This attracted Bitcoiners from all over Southern California. People brought their families. Some sat stackers sold wares outside as if it were a Farmer's Market. A couple kids sold some hats. One dude sold pins. I bought one off him. It resembled the Opendime I use as a keychain. He wore a 21M/infinity hat. We talked about Knut Svanholm books. He asked me, "What do you do for bitcoin?"
"I write a blog," I said. I must have written three articles about Bitcoin back then. I set up a BTCpayServer with LunaNode. My real idea was to write for sats, but I spent more sats on Lunanode than I made. I needed something to sell.
I had a few shitty ideas but no real business plan. I told Pins about one of these shitty ideas.
"I'm thinking about selling BIP39 raffle tickets, but they're a pain in the ass to cut." See what I mean, bad ideas.
Pins didn't say it was a bad idea though. I assure you, it was, but Pins gave this advice.
”Maybe you can use a 3D Printer."
I never did it, but I was impressed by how willing he was to help me. That's common in bitcoin. Bitcoiners are incentivized to help other Bitcoiners. The more people that accept Bitcoin at their stores, the bigger the demand for Bitcoin. The bigger the demand, the more the
Bitcoin Is For Spending
I participate in the circular economy because I consider using Bitcoin as money to be more advantageous for my savings strategy. When you earn sats, spend sats, and save sats, you break free from the chains of fiat debasement. Dollars are designed to go down in purchasing power to manipulate the public into spending more. That's why most people have more than one TV, but can't afford a $400 emergency. I spend Bitcoin because it forces me to be frugal. Fiat is designed to spend as quickly as possible since it will buy less groceries tomorrow than it will today.
Bitcoin is designed to buy more groceries tomorrow than it will today. When you expect $30 worth of Open AI services will likely be worth $433 in 21 years(if we assume Saylor is correct) you evaluate everything you buy with an orange colored lens. Your shopping habits change. A month of Chat GPT premium mightr be a month's worth of groceries in the future. I no longer buy Nike's because they coat 80k-120k sats, but I expect them to look like shredded cheese in six months. I would rather pay 100k sats for a nice pair of hiking shoes. I expect they will last me a few years.
Knowing this, you might ask, why would you spend Sats on a stupid pin? I've had my open dime pin for almost 4 years now and I expect to have it for years to come. It must have cost me about 100k sats. I don't expect it to be worth that much in the future, but you never know. Sometimes, I watch The Antique Road Show on PBS. Some pins, made by famous artists, are worth thousands of dollars. There is a chance collectibles like this will become more valuable, but I'm skeptical of this. I bought this PIN because it sparks joy, as Marie Kondo says.
This is not investment advice. Your Sats will almost certainly be worth more than your pins in the future, but if you buy a PIN from Salvador Dali, nobody stacks Sats. If you buy a PIN from BTCPins, a hardcore bitccoiner stack sats, which means less sats on the market will be availavle for 8 billion people when you buy a pin. Maybe pins will buy another hat from a bitccoiner, but that just means another bitccoiner stacks Sats. Notice how these Sats never make it back to the exchange because Bitcoiners know their stack will be more valuable in the future than they are today. So when you spend Sats, you only spend Sats on the things you find most valuable.
Pins I Bought Online
Although I consider these Pins art. I don't view art as an investment. I don't expect to ever sell one of these Pins for $110,000 like that banana duct-taped to a canvas before the artist got the munchies. I don't want dollars anyway. That's like a whole coin for a banana. I wouldn't spend 100,000,000 sats for one of these Pins, but BTCPins are not so pretentiously priced.
I recently bought some pins I've been salivating over for months. I need a better way of displaying them, but here are the pins I recently bought.

@ 4ba8e86d:89d32de4
2024-10-07 13:37:38O que é Cwtch? Cwtch (/kʊtʃ/ - uma palavra galesa que pode ser traduzida aproximadamente como “um abraço que cria um lugar seguro”) é um protocolo de mensagens multipartidário descentralizado, que preserva a privacidade, que pode ser usado para construir aplicativos resistentes a metadados.
Como posso pronunciar Cwtch? Como "kutch", para rimar com "butch".
Descentralizado e Aberto : Não existe “serviço Cwtch” ou “rede Cwtch”. Os participantes do Cwtch podem hospedar seus próprios espaços seguros ou emprestar sua infraestrutura para outras pessoas que buscam um espaço seguro. O protocolo Cwtch é aberto e qualquer pessoa é livre para criar bots, serviços e interfaces de usuário e integrar e interagir com o Cwtch.
Preservação de privacidade : toda a comunicação no Cwtch é criptografada de ponta a ponta e ocorre nos serviços cebola Tor v3.
Resistente a metadados : O Cwtch foi projetado de forma que nenhuma informação seja trocada ou disponibilizada a ninguém sem seu consentimento explícito, incluindo mensagens durante a transmissão e metadados de protocolo
Uma breve história do bate-papo resistente a metadados Nos últimos anos, a conscientização pública sobre a necessidade e os benefícios das soluções criptografadas de ponta a ponta aumentou com aplicativos como Signal , Whatsapp e Wire. que agora fornecem aos usuários comunicações seguras.
No entanto, essas ferramentas exigem vários níveis de exposição de metadados para funcionar, e muitos desses metadados podem ser usados para obter detalhes sobre como e por que uma pessoa está usando uma ferramenta para se comunicar.
Uma ferramenta que buscou reduzir metadados é o Ricochet lançado pela primeira vez em 2014. Ricochet usou os serviços cebola Tor v2 para fornecer comunicação criptografada segura de ponta a ponta e para proteger os metadados das comunicações.
Não havia servidores centralizados que auxiliassem no roteamento das conversas do Ricochet. Ninguém além das partes envolvidas em uma conversa poderia saber que tal conversa está ocorrendo.
Ricochet tinha limitações; não havia suporte para vários dispositivos, nem existe um mecanismo para suportar a comunicação em grupo ou para um usuário enviar mensagens enquanto um contato está offline.
Isto tornou a adoção do Ricochet uma proposta difícil; mesmo aqueles em ambientes que seriam melhor atendidos pela resistência aos metadados, sem saber que ela existe.
Além disso, qualquer solução para comunicação descentralizada e resistente a metadados enfrenta problemas fundamentais quando se trata de eficiência, privacidade e segurança de grupo conforme definido pelo consenso e consistência da transcrição.
Alternativas modernas ao Ricochet incluem Briar , Zbay e Ricochet Refresh - cada ferramenta procura otimizar para um conjunto diferente de compensações, por exemplo, Briar procura permitir que as pessoas se comuniquem mesmo quando a infraestrutura de rede subjacente está inoperante, ao mesmo tempo que fornece resistência à vigilância de metadados.
O projeto Cwtch começou em 2017 como um protocolo de extensão para Ricochet, fornecendo conversas em grupo por meio de servidores não confiáveis, com o objetivo de permitir aplicativos descentralizados e resistentes a metadados como listas compartilhadas e quadros de avisos.
Uma versão alfa do Cwtch foi lançada em fevereiro de 2019 e, desde então, a equipe do Cwtch dirigida pela OPEN PRIVACY RESEARCH SOCIETY conduziu pesquisa e desenvolvimento em cwtch e nos protocolos, bibliotecas e espaços de problemas subjacentes.
Modelo de Risco.
Sabe-se que os metadados de comunicações são explorados por vários adversários para minar a segurança dos sistemas, para rastrear vítimas e para realizar análises de redes sociais em grande escala para alimentar a vigilância em massa. As ferramentas resistentes a metadados estão em sua infância e faltam pesquisas sobre a construção e a experiência do usuário de tais ferramentas.
https://nostrcheck.me/media/public/nostrcheck.me_9475702740746681051707662826.webp
O Cwtch foi originalmente concebido como uma extensão do protocolo Ricochet resistente a metadados para suportar comunicações assíncronas de grupos multiponto por meio do uso de infraestrutura anônima, descartável e não confiável.
Desde então, o Cwtch evoluiu para um protocolo próprio. Esta seção descreverá os vários riscos conhecidos que o Cwtch tenta mitigar e será fortemente referenciado no restante do documento ao discutir os vários subcomponentes da Arquitetura Cwtch.
Modelo de ameaça.
É importante identificar e compreender que os metadados são omnipresentes nos protocolos de comunicação; é de facto necessário que tais protocolos funcionem de forma eficiente e em escala. No entanto, as informações que são úteis para facilitar peers e servidores também são altamente relevantes para adversários que desejam explorar tais informações.
Para a definição do nosso problema, assumiremos que o conteúdo de uma comunicação é criptografado de tal forma que um adversário é praticamente incapaz de quebrá-lo veja tapir e cwtch para detalhes sobre a criptografia que usamos, e como tal nos concentraremos em o contexto para os metadados de comunicação.
Procuramos proteger os seguintes contextos de comunicação:
• Quem está envolvido em uma comunicação? Pode ser possível identificar pessoas ou simplesmente identificadores de dispositivos ou redes. Por exemplo, “esta comunicação envolve Alice, uma jornalista, e Bob, um funcionário público”.
• Onde estão os participantes da conversa? Por exemplo, “durante esta comunicação, Alice estava na França e Bob estava no Canadá”.
• Quando ocorreu uma conversa? O momento e a duração da comunicação podem revelar muito sobre a natureza de uma chamada, por exemplo, “Bob, um funcionário público, conversou com Alice ao telefone por uma hora ontem à noite. Esta é a primeira vez que eles se comunicam.” *Como a conversa foi mediada? O fato de uma conversa ter ocorrido por meio de um e-mail criptografado ou não criptografado pode fornecer informações úteis. Por exemplo, “Alice enviou um e-mail criptografado para Bob ontem, enquanto eles normalmente enviam apenas e-mails de texto simples um para o outro”.
• Sobre o que é a conversa? Mesmo que o conteúdo da comunicação seja criptografado, às vezes é possível derivar um contexto provável de uma conversa sem saber exatamente o que é dito, por exemplo, “uma pessoa ligou para uma pizzaria na hora do jantar” ou “alguém ligou para um número conhecido de linha direta de suicídio na hora do jantar”. 3 horas da manhã."
Além das conversas individuais, também procuramos defender-nos contra ataques de correlação de contexto, através dos quais múltiplas conversas são analisadas para obter informações de nível superior:
• Relacionamentos: Descobrir relações sociais entre um par de entidades analisando a frequência e a duração de suas comunicações durante um período de tempo. Por exemplo, Carol e Eve ligam uma para a outra todos os dias durante várias horas seguidas.
• Cliques: Descobrir relações sociais entre um grupo de entidades que interagem entre si. Por exemplo, Alice, Bob e Eva se comunicam entre si.
• Grupos vagamente conectados e indivíduos-ponte: descobrir grupos que se comunicam entre si através de intermediários, analisando cadeias de comunicação (por exemplo, toda vez que Alice fala com Bob, ela fala com Carol quase imediatamente depois; Bob e Carol nunca se comunicam).
• Padrão de Vida: Descobrir quais comunicações são cíclicas e previsíveis. Por exemplo, Alice liga para Eve toda segunda-feira à noite por cerca de uma hora. Ataques Ativos
Ataques de deturpação.
O Cwtch não fornece registro global de nomes de exibição e, como tal, as pessoas que usam o Cwtch são mais vulneráveis a ataques baseados em declarações falsas, ou seja, pessoas que fingem ser outras pessoas:
O fluxo básico de um desses ataques é o seguinte, embora também existam outros fluxos:
•Alice tem um amigo chamado Bob e outro chamado Eve
• Eve descobre que Alice tem um amigo chamado Bob
• Eve cria milhares de novas contas para encontrar uma que tenha uma imagem/chave pública semelhante à de Bob (não será idêntica, mas pode enganar alguém por alguns minutos)
• Eve chama essa nova conta de "Eve New Account" e adiciona Alice como amiga.
• Eve então muda seu nome em "Eve New Account" para "Bob"
• Alice envia mensagens destinadas a "Bob" para a conta falsa de Bob de Eve Como os ataques de declarações falsas são inerentemente uma questão de confiança e verificação, a única maneira absoluta de evitá-los é os usuários validarem absolutamente a chave pública. Obviamente, isso não é o ideal e, em muitos casos, simplesmente não acontecerá .
Como tal, pretendemos fornecer algumas dicas de experiência do usuário na interface do usuário para orientar as pessoas na tomada de decisões sobre confiar em contas e/ou distinguir contas que possam estar tentando se representar como outros usuários.
Uma nota sobre ataques físicos A Cwtch não considera ataques que exijam acesso físico (ou equivalente) à máquina do usuário como praticamente defensáveis. No entanto, no interesse de uma boa engenharia de segurança, ao longo deste documento ainda nos referiremos a ataques ou condições que exigem tal privilégio e indicaremos onde quaisquer mitigações que implementámos falharão.
Um perfil Cwtch.
Os usuários podem criar um ou mais perfis Cwtch. Cada perfil gera um par de chaves ed25519 aleatório compatível com Tor.
Além do material criptográfico, um perfil também contém uma lista de Contatos (outras chaves públicas do perfil Cwtch + dados associados sobre esse perfil, como apelido e (opcionalmente) mensagens históricas), uma lista de Grupos (contendo o material criptográfico do grupo, além de outros dados associados, como apelido do grupo e mensagens históricas).
Conversões entre duas partes: ponto a ponto
https://nostrcheck.me/media/public/nostrcheck.me_2186338207587396891707662879.webp
Para que duas partes participem de uma conversa ponto a ponto, ambas devem estar on-line, mas apenas uma precisa estar acessível por meio do serviço Onion. Por uma questão de clareza, muitas vezes rotulamos uma parte como “ponto de entrada” (aquele que hospeda o serviço cebola) e a outra parte como “ponto de saída” (aquele que se conecta ao serviço cebola).
Após a conexão, ambas as partes adotam um protocolo de autenticação que:
• Afirma que cada parte tem acesso à chave privada associada à sua identidade pública.
• Gera uma chave de sessão efêmera usada para criptografar todas as comunicações futuras durante a sessão.
Esta troca (documentada com mais detalhes no protocolo de autenticação ) é negável offline , ou seja, é possível para qualquer parte falsificar transcrições desta troca de protocolo após o fato e, como tal - após o fato - é impossível provar definitivamente que a troca aconteceu de forma alguma.
Após o protocolo de autenticação, as duas partes podem trocar mensagens livremente.
Conversas em Grupo e Comunicação Ponto a Servidor
Ao iniciar uma conversa em grupo, é gerada uma chave aleatória para o grupo, conhecida como Group Key. Todas as comunicações do grupo são criptografadas usando esta chave. Além disso, o criador do grupo escolhe um servidor Cwtch para hospedar o grupo. Um convite é gerado, incluindo o Group Key, o servidor do grupo e a chave do grupo, para ser enviado aos potenciais membros.
Para enviar uma mensagem ao grupo, um perfil se conecta ao servidor do grupo e criptografa a mensagem usando a Group Key, gerando também uma assinatura sobre o Group ID, o servidor do grupo e a mensagem. Para receber mensagens do grupo, um perfil se conecta ao servidor e baixa as mensagens, tentando descriptografá-las usando a Group Key e verificando a assinatura.
Detalhamento do Ecossistema de Componentes
O Cwtch é composto por várias bibliotecas de componentes menores, cada uma desempenhando um papel específico. Algumas dessas bibliotecas incluem:
- abertoprivacidade/conectividade: Abstração de rede ACN, atualmente suportando apenas Tor.
- cwtch.im/tapir: Biblioteca para construção de aplicativos p2p em sistemas de comunicação anônimos.
- cwtch.im/cwtch: Biblioteca principal para implementação do protocolo/sistema Cwtch.
- cwtch.im/libcwtch-go: Fornece ligações C para Cwtch para uso em implementações de UI.
TAPIR: Uma Visão Detalhada
Projetado para substituir os antigos canais de ricochete baseados em protobuf, o Tapir fornece uma estrutura para a construção de aplicativos anônimos.
Está dividido em várias camadas:
• Identidade - Um par de chaves ed25519, necessário para estabelecer um serviço cebola Tor v3 e usado para manter uma identidade criptográfica consistente para um par.
• Conexões – O protocolo de rede bruto que conecta dois pares. Até agora, as conexões são definidas apenas através do Tor v3 Onion Services.
• Aplicativos - As diversas lógicas que permitem um determinado fluxo de informações em uma conexão. Os exemplos incluem transcrições criptográficas compartilhadas, autenticação, proteção contra spam e serviços baseados em tokens. Os aplicativos fornecem recursos que podem ser referenciados por outros aplicativos para determinar se um determinado peer tem a capacidade de usar um determinado aplicativo hospedado.
• Pilhas de aplicativos - Um mecanismo para conectar mais de um aplicativo, por exemplo, a autenticação depende de uma transcrição criptográfica compartilhada e o aplicativo peer cwtch principal é baseado no aplicativo de autenticação.
Identidade.
Um par de chaves ed25519, necessário para estabelecer um serviço cebola Tor v3 e usado para manter uma identidade criptográfica consistente para um peer.
InitializeIdentity - de um par de chaves conhecido e persistente:i,I
InitializeEphemeralIdentity - de um par de chaves aleatório: ie,Ie
Aplicativos de transcrição.
Inicializa uma transcrição criptográfica baseada em Merlin que pode ser usada como base de protocolos baseados em compromisso de nível superior
O aplicativo de transcrição entrará em pânico se um aplicativo tentar substituir uma transcrição existente por uma nova (aplicando a regra de que uma sessão é baseada em uma e apenas uma transcrição).
Merlin é uma construção de transcrição baseada em STROBE para provas de conhecimento zero. Ele automatiza a transformação Fiat-Shamir, para que, usando Merlin, protocolos não interativos possam ser implementados como se fossem interativos.
Isto é significativamente mais fácil e menos sujeito a erros do que realizar a transformação manualmente e, além disso, também fornece suporte natural para:
• protocolos multi-round com fases alternadas de commit e desafio;
• separação natural de domínios, garantindo que os desafios estejam vinculados às afirmações a serem provadas;
• enquadramento automático de mensagens, evitando codificação ambígua de dados de compromisso;
• e composição do protocolo, usando uma transcrição comum para vários protocolos.
Finalmente, o Merlin também fornece um gerador de números aleatórios baseado em transcrição como defesa profunda contra ataques de entropia ruim (como reutilização de nonce ou preconceito em muitas provas). Este RNG fornece aleatoriedade sintética derivada de toda a transcrição pública, bem como dos dados da testemunha do provador e uma entrada auxiliar de um RNG externo.
Conectividade Cwtch faz uso do Tor Onion Services (v3) para todas as comunicações entre nós.
Fornecemos o pacote openprivacy/connectivity para gerenciar o daemon Tor e configurar e desmontar serviços cebola através do Tor.
Criptografia e armazenamento de perfil.
Os perfis são armazenados localmente no disco e criptografados usando uma chave derivada de uma senha conhecida pelo usuário (via pbkdf2).
Observe que, uma vez criptografado e armazenado em disco, a única maneira de recuperar um perfil é recuperando a senha - como tal, não é possível fornecer uma lista completa de perfis aos quais um usuário pode ter acesso até inserir uma senha.
Perfis não criptografados e a senha padrão Para lidar com perfis "não criptografados" (ou seja, que não exigem senha para serem abertos), atualmente criamos um perfil com uma senha codificada de fato .
Isso não é o ideal, preferiríamos confiar no material de chave fornecido pelo sistema operacional, de modo que o perfil fosse vinculado a um dispositivo específico, mas esses recursos são atualmente uma colcha de retalhos - também notamos, ao criar um perfil não criptografado, pessoas que usam Cwtch estão explicitamente optando pelo risco de que alguém com acesso ao sistema de arquivos possa descriptografar seu perfil.
Vulnerabilidades Relacionadas a Imagens e Entrada de Dados
Imagens Maliciosas
O Cwtch enfrenta desafios na renderização de imagens, com o Flutter utilizando Skia, embora o código subjacente não seja totalmente seguro para a memória.
Realizamos testes de fuzzing nos componentes Cwtch e encontramos um bug de travamento causado por um arquivo GIF malformado, levando a falhas no kernel. Para mitigar isso, adotamos a política de sempre habilitar cacheWidth e/ou cacheHeight máximo para widgets de imagem.
Identificamos o risco de imagens maliciosas serem renderizadas de forma diferente em diferentes plataformas, como evidenciado por um bug no analisador PNG da Apple.
Riscos de Entrada de Dados
Um risco significativo é a interceptação de conteúdo ou metadados por meio de um Input Method Editor (IME) em dispositivos móveis. Mesmo aplicativos IME padrão podem expor dados por meio de sincronização na nuvem, tradução online ou dicionários pessoais.
Implementamos medidas de mitigação, como enableIMEPersonalizedLearning: false no Cwtch 1.2, mas a solução completa requer ações em nível de sistema operacional e é um desafio contínuo para a segurança móvel.
Servidor Cwtch.
O objetivo do protocolo Cwtch é permitir a comunicação em grupo através de infraestrutura não confiável .
Ao contrário dos esquemas baseados em retransmissão, onde os grupos atribuem um líder, um conjunto de líderes ou um servidor confiável de terceiros para garantir que cada membro do grupo possa enviar e receber mensagens em tempo hábil (mesmo que os membros estejam offline) - infraestrutura não confiável tem o objetivo de realizar essas propriedades sem a suposição de confiança.
O artigo original do Cwtch definia um conjunto de propriedades que se esperava que os servidores Cwtch fornecessem:
• O Cwtch Server pode ser usado por vários grupos ou apenas um.
• Um servidor Cwtch, sem a colaboração de um membro do grupo, nunca deve aprender a identidade dos participantes de um grupo.
• Um servidor Cwtch nunca deve aprender o conteúdo de qualquer comunicação.
• Um servidor Cwtch nunca deve ser capaz de distinguir mensagens como pertencentes a um grupo específico. Observamos aqui que essas propriedades são um superconjunto dos objetivos de design das estruturas de Recuperação de Informações Privadas.
Melhorias na Eficiência e Segurança
Eficiência do Protocolo
Atualmente, apenas um protocolo conhecido, o PIR ingênuo, atende às propriedades desejadas para garantir a privacidade na comunicação do grupo Cwtch. Este método tem um impacto direto na eficiência da largura de banda, especialmente para usuários em dispositivos móveis. Em resposta a isso, estamos ativamente desenvolvendo novos protocolos que permitem negociar garantias de privacidade e eficiência de maneiras diversas.
Os servidores, no momento desta escrita, permitem o download completo de todas as mensagens armazenadas, bem como uma solicitação para baixar mensagens específicas a partir de uma determinada mensagem. Quando os pares ingressam em um grupo em um novo servidor, eles baixam todas as mensagens do servidor inicialmente e, posteriormente, apenas as mensagens novas.
Mitigação de Análise de Metadados
Essa abordagem permite uma análise moderada de metadados, pois o servidor pode enviar novas mensagens para cada perfil suspeito exclusivo e usar essas assinaturas de mensagens exclusivas para rastrear sessões ao longo do tempo. Essa preocupação é mitigada por dois fatores:
- Os perfis podem atualizar suas conexões a qualquer momento, resultando em uma nova sessão do servidor.
- Os perfis podem ser "ressincronizados" de um servidor a qualquer momento, resultando em uma nova chamada para baixar todas as mensagens. Isso é comumente usado para buscar mensagens antigas de um grupo.
Embora essas medidas imponham limites ao que o servidor pode inferir, ainda não podemos garantir resistência total aos metadados. Para soluções futuras para esse problema, consulte Niwl.
Proteção contra Pares Maliciosos
Os servidores enfrentam o risco de spam gerado por pares, representando uma ameaça significativa à eficácia do sistema Cwtch. Embora tenhamos implementado um mecanismo de proteção contra spam no protótipo do Cwtch, exigindo que os pares realizem alguma prova de trabalho especificada pelo servidor, reconhecemos que essa não é uma solução robusta na presença de um adversário determinado com recursos significativos.
Pacotes de Chaves
Os servidores Cwtch se identificam por meio de pacotes de chaves assinados, contendo uma lista de chaves necessárias para garantir a segurança e resistência aos metadados na comunicação do grupo Cwtch. Esses pacotes de chaves geralmente incluem três chaves: uma chave pública do serviço Tor v3 Onion para o Token Board, uma chave pública do Tor v3 Onion Service para o Token Service e uma chave pública do Privacy Pass.
Para verificar os pacotes de chaves, os perfis que os importam do servidor utilizam o algoritmo trust-on-first-use (TOFU), verificando a assinatura anexada e a existência de todos os tipos de chave. Se o perfil já tiver importado o pacote de chaves do servidor anteriormente, todas as chaves são consideradas iguais.
Configuração prévia do aplicativo para ativar o Relé do Cwtch.
No Android, a hospedagem de servidor não está habilitada, pois essa opção não está disponível devido às limitações dos dispositivos Android. Essa funcionalidade está reservada apenas para servidores hospedados em desktops.
No Android, a única forma direta de importar uma chave de servidor é através do grupo de teste Cwtch, garantindo assim acesso ao servidor Cwtch.
Primeiro passo é Habilitar a opção de grupo no Cwtch que está em fase de testes. Clique na opção no canto superior direito da tela de configuração e pressione o botão para acessar as configurações do Cwtch.
Você pode alterar o idioma para Português do Brasil.Depois, role para baixo e selecione a opção para ativar os experimentos. Em seguida, ative a opção para habilitar o chat em grupo e a pré-visualização de imagens e fotos de perfil, permitindo que você troque sua foto de perfil.

Selecione se deseja proteger
este perfil e salvo localmente com criptografia forte: Senha: sua conta está protegida de outras pessoas que possam usar este dispositivo
Sem senha: qualquer pessoa que tenha acesso a este dispositivo poderá acessar este perfil.
Preencha sua senha e digite-a novamente
Os perfis são armazenados localmente no disco e criptografados usando uma chave derivada de uma senha conhecida pelo usuário (via pbkdf2).
Observe que, uma vez criptografado e armazenado em disco, a única maneira de recuperar um perfil é recuperando a chave da senha - como tal, não é possível fornecer uma lista completa de perfis aos quais um usuário pode ter acesso até inserir um senha.

O próximo passo é adicionar o FuzzBot, que é um bot de testes e de desenvolvimento.
Contato do FuzzBot: 4y2hxlxqzautabituedksnh2ulcgm2coqbure6wvfpg4gi2ci25ta5ad.
Ao enviar o comando "testgroup-invite" para o FuzzBot, você receberá um convite para entrar no Grupo Cwtch Test. Ao ingressar no grupo, você será automaticamente conectado ao servidor Cwtch. Você pode optar por sair do grupo a qualquer momento ou ficar para conversar e tirar dúvidas sobre o aplicativo e outros assuntos. Depois, você pode configurar seu próprio servidor Cwtch, o que é altamente recomendável.

Agora você pode utilizar o aplicativo normalmente. Algumas observações que notei: se houver demora na conexão com outra pessoa, ambas devem estar online. Se ainda assim a conexão não for estabelecida, basta clicar no ícone de reset do Tor para restabelecer a conexão com a outra pessoa.
Uma introdução aos perfis Cwtch.
Com Cwtch você pode criar um ou mais perfis . Cada perfil gera um par de chaves ed25519 aleatório compatível com a Rede Tor.
Este é o identificador que você pode fornecer às pessoas e que elas podem usar para entrar em contato com você via Cwtch.
Cwtch permite criar e gerenciar vários perfis separados. Cada perfil está associado a um par de chaves diferente que inicia um serviço cebola diferente.
Gerenciar Na inicialização, o Cwtch abrirá a tela Gerenciar Perfis. Nessa tela você pode:
- Crie um novo perfil.
- Desbloquear perfis.
- Criptografados existentes.
- Gerenciar perfis carregados.
- Alterando o nome de exibição de um perfil.
- Alterando a senha de um perfil Excluindo um perfil.
- Alterando uma imagem de perfil.
Backup ou exportação de um perfil.
Na tela de gerenciamento de perfil:
-
Selecione o lápis ao lado do perfil que você deseja editar
-
Role para baixo até a parte inferior da tela.
-
Selecione "Exportar perfil"
-
Escolha um local e um nome de arquivo.
5.confirme.
Uma vez confirmado, o Cwtch colocará uma cópia do perfil no local indicado. Este arquivo é criptografado no mesmo nível do perfil.
Este arquivo pode ser importado para outra instância do Cwtch em qualquer dispositivo.
Importando um perfil.
-
Pressione o +botão de ação no canto inferior direito e selecione "Importar perfil"
-
Selecione um arquivo de perfil Cwtch exportado para importar
-
Digite a senha associada ao perfil e confirme.
Uma vez confirmado, o Cwtch tentará descriptografar o arquivo fornecido usando uma chave derivada da senha fornecida. Se for bem-sucedido, o perfil aparecerá na tela Gerenciamento de perfil e estará pronto para uso.
OBSERVAÇÃO Embora um perfil possa ser importado para vários dispositivos, atualmente apenas uma versão de um perfil pode ser usada em todos os dispositivos ao mesmo tempo. As tentativas de usar o mesmo perfil em vários dispositivos podem resultar em problemas de disponibilidade e falhas de mensagens.
Qual é a diferença entre uma conexão ponto a ponto e um grupo cwtch?
As conexões ponto a ponto Cwtch permitem que 2 pessoas troquem mensagens diretamente. As conexões ponto a ponto nos bastidores usam serviços cebola Tor v3 para fornecer uma conexão criptografada e resistente a metadados. Devido a esta conexão direta, ambas as partes precisam estar online ao mesmo tempo para trocar mensagens.
Os Grupos Cwtch permitem que várias partes participem de uma única conversa usando um servidor não confiável (que pode ser fornecido por terceiros ou auto-hospedado). Os operadores de servidores não conseguem saber quantas pessoas estão em um grupo ou o que está sendo discutido. Se vários grupos estiverem hospedados em um único servidor, o servidor não conseguirá saber quais mensagens pertencem a qual grupo sem a conivência de um membro do grupo. Ao contrário das conversas entre pares, as conversas em grupo podem ser conduzidas de forma assíncrona, para que todos num grupo não precisem estar online ao mesmo tempo.
Por que os grupos cwtch são experimentais? Mensagens em grupo resistentes a metadados ainda são um problema em aberto . Embora a versão que fornecemos no Cwtch Beta seja projetada para ser segura e com metadados privados, ela é bastante ineficiente e pode ser mal utilizada. Como tal, aconselhamos cautela ao usá-lo e apenas o fornecemos como um recurso opcional.
Como posso executar meu próprio servidor Cwtch? A implementação de referência para um servidor Cwtch é de código aberto . Qualquer pessoa pode executar um servidor Cwtch, e qualquer pessoa com uma cópia do pacote de chaves públicas do servidor pode hospedar grupos nesse servidor sem que o operador tenha acesso aos metadados relacionados ao grupo .

2024-10-26 12:21:50Es ist besser, ein Licht zu entzünden, als auf die Dunkelheit zu schimpfen. Konfuzius
Die Bemühungen um Aufarbeitung der sogenannten Corona-Pandemie, um Aufklärung der Hintergründe, Benennung von Verantwortlichkeiten und das Ziehen von Konsequenzen sind durchaus nicht eingeschlafen. Das Interesse daran ist unter den gegebenen Umständen vielleicht nicht sonderlich groß, aber es ist vorhanden.
Der sächsische Landtag hat gestern die Einsetzung eines Untersuchungsausschusses zur Corona-Politik beschlossen. In einer Sondersitzung erhielt ein entsprechender Antrag der AfD-Fraktion die ausreichende Zustimmung, auch von einigen Abgeordneten des BSW.
In den Niederlanden wird Bill Gates vor Gericht erscheinen müssen. Sieben durch die Covid-«Impfstoffe» geschädigte Personen hatten Klage eingereicht. Sie werfen unter anderem Gates, Pfizer-Chef Bourla und dem niederländischen Staat vor, sie hätten gewusst, dass diese Präparate weder sicher noch wirksam sind.
Mit den mRNA-«Impfstoffen» von Pfizer/BioNTech befasst sich auch ein neues Buch. Darin werden die Erkenntnisse von Ärzten und Wissenschaftlern aus der Analyse interner Dokumente über die klinischen Studien der Covid-Injektion präsentiert. Es handelt sich um jene in den USA freigeklagten Papiere, die die Arzneimittelbehörde (Food and Drug Administration, FDA) 75 Jahre unter Verschluss halten wollte.
Ebenfalls Wissenschaftler und Ärzte, aber auch andere Experten organisieren als Verbundnetzwerk Corona-Solution kostenfreie Online-Konferenzen. Ihr Ziel ist es, «wissenschaftlich, demokratisch und friedlich» über Impfstoffe und Behandlungsprotokolle gegen SARS-CoV-2 aufzuklären und die Diskriminierung von Ungeimpften zu stoppen. Gestern fand eine weitere Konferenz statt. Ihr Thema: «Corona und modRNA: Von Toten, Lebenden und Physik lernen».
Aufgrund des Digital Services Acts (DSA) der Europäischen Union sei das Risiko groß, dass ihre Arbeit als «Fake-News» bezeichnet würde, so das Netzwerk. Staatlich unerwünschte wissenschaftliche Aufklärung müsse sich passende Kanäle zur Veröffentlichung suchen. Ihre Live-Streams seien deshalb zum Beispiel nicht auf YouTube zu finden.
Der vielfältige Einsatz für Aufklärung und Aufarbeitung wird sich nicht stummschalten lassen. Nicht einmal der Zensurmeister der EU, Deutschland, wird so etwas erreichen. Die frisch aktivierten «Trusted Flagger» dürften allerdings künftige Siege beim «Denunzianten-Wettbewerb» im Kontext des DSA zusätzlich absichern.
Wo sind die Grenzen der Meinungsfreiheit? Sicher gibt es sie. Aber die ideologische Gleichstellung von illegalen mit unerwünschten Äußerungen verfolgt offensichtlich eher das Ziel, ein derart elementares demokratisches Grundrecht möglichst weitgehend auszuhebeln. Vorwürfe wie «Hassrede», «Delegitimierung des Staates» oder «Volksverhetzung» werden heute inflationär verwendet, um Systemkritik zu unterbinden. Gegen solche Bestrebungen gilt es, sich zu wehren.

@ 8d34bd24:414be32b
2025-02-02 21:31:11This Sunday our pastor had to give a sermon with very little preparation. He was leading an elders’ retreat and one of the elders was supposed to preach in his place. The elder who had prepared a sermon ended up in the hospital, so our pastor had to prep fast. He did a great thing. He preached on a passage, but also used that passage to demonstrate how he studies scripture. It was a great sermon. The passage he preached on reminded me of a time in my past when I learned some important lessons.
Almost 20 years ago, I was leading a high school girls Bible study. They picked out a book about Mary and Martha to study. Initially, I wasn’t thrilled with their choice, but didn’t have a theological problem with it, so I agreed for us to study this book. (I don’t remember the name of the book and all my books burnt up when my house burnt down almost 10 years ago). In the end, I probably got more out of the study than any of the girls because I have a definite tendency to be a Martha. What was Martha’s error? Let’s check out the passage:
Now as they went on their way, Jesus entered a village. And a woman named Martha welcomed him into her house. And she had a sister called Mary, who sat at the Lord’s feet and listened to his teaching. But Martha was distracted with much serving. And she went up to him and said, “Lord, do you not care that my sister has left me to serve alone? Tell her then to help me.” But the Lord answered her, “Martha, Martha, you are anxious and troubled about many things, but one thing is necessary. Mary has chosen the good portion, which will not be taken away from her.” (Luke 10:38-42 ESV)
Jesus visited two sisters who welcomed Him into their home. Mary sat at Jesus’s feet and listened to His teaching. Martha spent her time serving everyone and taking care of everyone’s physical needs.
Is taking care of their home and the needs of their guests a bad thing? Of course not, but is it the best?
To make things much worse, Martha then got upset because her sister Mary wasn’t helping her. She was just sitting there taking in every word that Jesus said. Most of us would think Martha’s sacrifices to take care of everyone was better than Mary’s choice to just sit at Jesus’s feet, but did Martha really choose the better path?
Martha then showed that her heart wasn’t focused right and she wasn’t putting the most important things first. She complained to Jesus about her sister’s failure to help and even commanded her Creator, “Tell her then to help me.” Instead of focusing on the words of Jesus, her frustration led her to command her God to act in the way she desired. She was so busy with cooking, cleaning, and serving, that she missed the most important things — spending time with and listening to her God, who was right there in her house with her. This was an opportunity that shouldn’t be missed due to busyness.
How often do we all do this same thing? How often are busy doing good things and miss the most important things? How often are we busy doing ministry that we forget about the reason for the ministry? I don’t know about you, but this happens to me a lot more often than I would like to admit. My biggest sins are usually not what most people think of as sins. My biggest sins are getting so busy that I leave God out of my life. I am so busy serving God that I forget to follow His leading. I am so busy doing what most people would consider good things, but if God is not part of them, they are not worth much. Because I am focusing on getting things done, worry and stress overtake me harming my health and my relationship with Jesus.
I don’t think this is taking Scripture out of context:
We have come to know and have believed the love which God has for us. God is love, and the one who abides in love abides in God, and God abides in him. (1 John 4:16) {emphasis mine}
Knowing that God is love, read the following passage replacing love with God.
If I speak with the tongues of men and of angels, but do not have love, I have become a noisy gong or a clanging cymbal. If I have the gift of prophecy, and know all mysteries and all knowledge; and if I have all faith, so as to remove mountains, but do not have love, I am nothing. And if I give all my possessions to feed the poor, and if I surrender my body to be burned, but do not have love, it profits me nothing. (1 Corinthians 13:1-3)
If I do not include God in my every action, “it profits me nothing.”
In reality it shouldn’t be allowing God to join me in my works, but me joining God in His works. It should be me listening to God’s word and the leading of the Holy Spirit, looking and seeing what God is doing around me, and me joining in His great works. It should be me allowing God to use me as a tool.
There are times that God speaks clearly and directly to us about what He desires for our lives, but most of the time, He speaks through His word — the Bible. Knowing the Bible helps us to know His will and His eternal plan, so we can follow Him and join Him in His work. Knowing the Bible helps us to differentiate between what is good and what is God’s best. It helps us to prioritize what is really important.
And this I pray, that your love may abound still more and more in real knowledge and all discernment, so that you may approve the things that are excellent, in order to be sincere and blameless until the day of Christ; having been filled with the fruit of righteousness which comes through Jesus Christ, to the glory and praise of God. (Philippians 1:9-11) {emphasis mine}
We can’t obey God, imitate Christ, or follow Him if we refuse to listen and that means spending time in the Bible and time in prayer with Him.
“Listen to Me, you stubborn-minded, Who are far from righteousness.” (Isaiah 46:12)
Come, you children, listen to me; I will teach you the fear of the Lord . (Psalm 34:11)
“Now therefore, O sons, listen to me, For blessed are they who keep my ways. (Proverbs 8:32)
But seek first His kingdom and His righteousness, and all these things will be added to you. (Matthew 6:33)
Our focus on Jesus/God must go beyond knowing Him. It is equally important to obey.
And He [Jesus] said to another, “Follow Me.” But he said, “Lord, permit me first to go and bury my father.” But He said to him, “Allow the dead to bury their own dead; but as for you, go and proclaim everywhere the kingdom of God.” (Luke 9:59-60) [clarification mine]
Once we know what He wants from us, we need to instantly drop what we are doing and follow Him. We can’t put other things ahead of obeying God.
For amazement had seized him and all his companions because of the catch of fish which they had taken; and so also were James and John, sons of Zebedee, who were partners with Simon. And Jesus said to Simon, “Do not fear, from now on you will be catching men.” When they had brought their boats to land, they left everything and followed Him. (Luke 5:9-11) {emphasis mine}
We should be like these apostles, that, after their most successful catch of fish in their entire career as fishermen, “they left everything and followed Him.” We need to let go of what we think is important and obey Him. We need to change our priorities to match God’s priorities.
That may mean we change careers to one that allows more free time for ministry or even going into full time ministry. It may mean letting go on keeping the perfect, clean house, so there is time for ministry, Bible study, or discipling our kids. It may mean changing your habits from watching TV with your family to reading the Bible with your family. For each of us, it will look different, but we need to be like Mary and choose to sit “at the Lord’s feet and listened to his teaching.” We need to be like the apostles who “left everything and followed Him.” We need to choose to put Jesus’s plans before our own. We need to choose to make God’s values our values.
But this is what I commanded them, saying, ‘Obey My voice, and I will be your God, and you will be My people; and you will walk in all the way which I command you, that it may be well with you.’ (Jeremiah 7:23)
Like so many things, it is simple, but it isn’t necessarily easy. We have to change the way we think in order to obey faithfully.
If anyone serves Me, he must follow Me; and where I am, there My servant will be also; if anyone serves Me, the Father will honor him. (John 12:26)
We have to change our priorities to God’s priorities.
Then Jesus said to His disciples, “If anyone wishes to come after Me, he must deny himself, and take up his cross and follow Me. (Matthew 16:24)
We need to seek God, His word, and His presence.
As the deer pants for the water brooks,\ So my soul pants for You, O God.\ My soul thirsts for God, for the living God;\ When shall I come and appear before God? (Psalm 42:1-2)
We need to be in God’s word daily, so we know who God is and what He desires from us.
How can a young man keep his way pure?\ By keeping it according to Your word.\ With all my heart I have sought You;\ Do not let me wander from Your commandments.\ *Your word I have treasured in my heart*,\ That I may not sin against You.\ Blessed are You, O Lord;\ Teach me Your statutes.\ With my lips I have told of\ All the ordinances of Your mouth.\ I have rejoiced in the way of Your testimonies,\ As much as in all riches.\ *I will meditate on Your precepts*\ And regard Your ways.\ I shall delight in Your statutes;\ I shall not forget Your word. (Psalm 119:9-16) {emphasis mine}
We need to read the Bible cover to cover so we know the whole word of God. Once we have read through the Bible multiple times, we need to spend time studying the Bible in more depth, so we can know the details, see how the different parts relate to each other, and grow in our knowledge of God. We need to study the Bible and use this knowledge to guide every decision in life — big and small.
Yet they did not listen or incline their ears, but stiffened their necks in order not to listen or take correction. (Jeremiah 17:23)
Just reading the Bible or sitting in church listening to sermons will not make a difference if we don’t truly listen and internalize God’s word, so we can apply it in our every day life. God knows what is best for us and we will never be truly at peace or have true joy until we are living our lives in the light of God’s word and direction.
My prayer for you and for me is that we will have the heart of Mary rather than the heart of Martha and that we will faithfully seek and follow God all of the days of our lives.
Trust Jesus.

2024-10-02 13:57:31Chain Duel, a fast paced PvP game that takes inspiration from the classic snake game and supercharges it with Bitcoin’s Lightning Network. Imagine battling another player for dominance in a race to collect blocks, where the length of your chain isn’t just a visual cue. It represents real, staked satoshis. The player with the most Proof of Work wins, but it’s not just about gameplay; it’s about the seamless integration of the Lightning Network and real-time payments.
But how does Chain Duel manage these instant transactions with such efficiency? That’s where LNbits comes in. LNbits, an open-source wallet and payment infrastructure, handles all in-game payments making it easy for developers to focus on gameplay while LNbits takes care of everything from microtransactions to automated splits for developers and designers. In this article, we’ll dive deep into how Chain Duel leverages LNbits to streamline in-game payments and how other developers can take advantage of this powerful toolset to build the future of Lightning-powered gaming.
Let’s explore how LNbits transforms payment processing and why it’s quickly becoming a must-have for game developers working in the Bitcoin space.
Overview of Chain Duel
Chain Duel is a unique Lightning Network-inspired game that reimagines the classic snake game with a competitive twist, integrating real-time payments. Two players face off in real-time, racing to "catch" blocks and extend their chains. Each block added to the chain represents Proof of Work, and the player with the most Proof of Work wins the duel. The stakes are high, as the game represents satoshis (small units of Bitcoin) as points, with the winner taking home the prize.
The game is designed to be Lightning-native, meaning all payments within Chain Duel are processed through the Lightning Network. This ensures fast payments, reducing latency and making gameplay smooth. With additional features like practice mode, tournaments and highscores, Chain Duel creates an engaging and competitive environment for Bitcoin enthusiasts and gamers alike.
One of the standout aspects of Chain Duel is its deeper integration with the Lightning Network even at a design level. For example, actual Bitcoin blocks can appear on screen during matches, offering bonus points when mined in sync with the game. The game’s current version, still in beta, has already drawn attention within the Bitcoin community, gaining momentum at conferences and with a growing user base through its social networks. With its innovative combination of gaming, the Lightning Network, and competitive play, Chain Duel offers a glimpse into the future of Lightning-based gaming.
How LNbits is Used in Chain Duel
Seamless Integration with LNbits
At the core of Chain Duel’s efficient payment processing is LNbits, which handles in-game transactions smoothly and reliably. Chain Duel uses the LNbits LNURL-pay and LNURL-withdraw extensions to manage payments and rewards between players. Before each match, players send satoshis using LNURL-pay, which generates a static QR code or link for making the payment. LNURL-pay allows users to attach a note to the payment, which Chain Duel creatively uses as a way to insert the player name in-game. The simplicity of LNURL-pay ensures that users can quickly and easily initiate games, with fresh invoices being issued for every game. When players win, LNURL-withdraw enables them to seamlessly pull their earnings from the game, providing a quick payout system.
These extensions make it easy for players to send and receive Bitcoin with minimal latency, fully leveraging the power of the Lightning Network for fast and low-cost payments. The flexibility of LNbits’ tools means that game developers don’t need to worry about building custom payment systems from scratch—they can rely on LNbits to handle all financial transactions with precision.
Lightning Tournaments
Chain Duel tournaments leverage LNbits and its LNURL extensions to create a seamless and efficient experience for players. In Chain Duel tournaments, LNbits plays a crucial role in managing the overall economics. LNbits facilitates the generation of LNURL QR codes that participants can scan to register quickly or withdraw their winnings. LNbits allows Chain Duel to automatically handle multiple registrations through LNURL-pay, enabling players to participate in the tournament without additional steps. The Lightning Network's speed ensures that these payments occur in real-time, reducing wait times and allowing for a smoother flow in-game.
Splitting Payments
LNbits further simplifies revenue-sharing within Chain Duel. This feature allows the game to automatically split the satoshis sent by players into different shares for the game’s developer, designer, and host. Each time a payment is made to join a match, LNbits is used to automattically pay each of the contributors, according to pre-defined rules. This automated process ensures that everyone involved in the development and running of the game gets their fair share without manual intervention or complex bookkeeping.
Nostr Integration
Chain Duel also integrates with Nostr, a decentralized protocol for social interactions. Players can join games using "Zaps", small tips or micropayments sent over the Lightning Network within the Nostr ecosystem. Through NIP-57, which enables Nostr clients to request Zap invoices, players can use LNURL-pay enabled Zaps to register in P2P matches, further enhancing the Chain Duel experience. By using Zaps as a way to register in-game, Chain Duel automates the process of fetching players' identity, creating a more competitive and social experience. Zaps are public on the Nostr network, further expanding Chain Duel's games social reach and community engagement.
Game and Payment Synchronization
One of the key reasons Chain Duel developers chose LNbits is its powerful API that connects directly with the game’s logic. LNbits allows the game to synchronize payments with gameplay in real-time, providing a seamless experience where payments are an integrated part of the gaming mechanics.
With LNbits managing both the payment process and the Lightning Network’s complex infrastructure, Chain Duel developers are free to concentrate on enhancing the competitive and Lightning Network-related aspects of the game. This division of tasks is essential for streamlining development while still providing an innovative in-game payment experience that is deeply integrated with the Bitcoin network.
LNbits proves to be an indispensable tool for Chain Duel, enabling smooth in-game transactions, real-time revenue sharing, and seamless integration with Nostr. For developers looking to build Lightning-powered games, LNbits offers a powerful suite of tools that handle everything from micropayments to payment distribution—ensuring that the game's focus remains on fun and competition rather than complex payment systems.
LNBits facilitating Education and Adoption
This system contributes to educating users on the power of the Lightning Network. Since Chain Duel directly involve real satoshis and LNURL for registration and rewards, players actively experience how Lightning can facilitate fast, cheap, and permissionless payments. By incorporating LNbits into Chain Duel, the game serves as an educational tool that introduces users to the benefits of the Lightning Network. Players gain direct experience using Lightning wallets and LNURL, helping them understand how these tools work in real-world scenarios. The near-instant nature of these payments showcases the power of Lightning in a practical context, highlighting its potential beyond just gaming. Players are encouraged to set up wallets, explore the Lightning ecosystem, and eventually become familiar with Bitcoin and Lightning technology. By integrating LNbits, Chain Duel transforms in-game payments into a learning opportunity, making Bitcoin and Lightning more approachable for users worldwide.
Tools for Developers
LNbits is a versatile, open-source platform designed to simplify and enhance Bitcoin Lightning Network wallet management. For developers, particularly those working on Lightning-native games like Chain Duel, LNbits offers an invaluable set of tools that allow for seamless integration of Lightning payments without the need to build complex custom solutions from scratch. LNbits is built on a modular and extensible architecture, enabling developers to easily add or create functionality suited to their project’s needs.
Extensible Architecture for Customization
At the core of LNbits is a simple yet powerful wallet system that developers can access across multiple devices. What makes LNbits stand out is its extensible nature—everything beyond the core functionality is implemented as an extension. This modular approach allows users to customize their LNbits installation by enabling or building extensions to suit specific use cases. This flexibility is perfect for developers who want to add Lightning-based services to their games or apps without modifying the core codebase.
- Extensions for Every Use Case
LNbits comes with a wide array of built-in extensions created by contributors, offering various services that can be plugged into your application. Some popular extensions include: - Faucets: Distribute small amounts of Bitcoin to users for testing or promotional purposes.
- Paylinks: Create shareable links for instant payments.
- Points-of-sale (PoS): Allow users to set up shareable payment terminals.
- Paywalls: Charge users to access content or services.
- Event tickets: Sell tickets for events directly via Lightning payments.
- Games and services: From dice games to jukeboxes, LNbits offers entertaining and functional tools.
These ready-made solutions can be adapted and used in different gaming scenarios, for example in Chain Duel, where LNURL extensions are used for in game payments. The extensibility ensures developers can focus on building engaging gameplay while LNbits handles payment flows.
Developer-Friendly Customization
LNbits isn't just a plug-and-play platform. Developers can extend its functionality even further by creating their own extensions, giving full control over how the wallet system is integrated into their games or apps. The architecture is designed to make it easy for developers to build on top of the platform, adding custom features for specific requirements.
Flexible Funding Source Management
LNbits also offers flexibility in terms of managing funding sources. Developers can easily connect LNbits to various Lightning Network node implementations, enabling seamless transitions between nodes or even different payment systems. This allows developers to switch underlying funding sources with minimal effort, making LNbits adaptable for games that may need to scale quickly or rely on different payment infrastructures over time.
A Lean Core System for Maximum Efficiency
Thanks to its modular architecture, LNbits maintains a lean core system. This reduces complexity and overhead, allowing developers to implement only the features they need. By avoiding bloated software, LNbits ensures faster transactions and less resource consumption, which is crucial in fast-paced environments like Chain Duel where speed and efficiency are paramount.
LNbits is designed with developers in mind, offering a suite of tools and a flexible infrastructure that makes integrating Bitcoin payments easy. Whether you’re developing games, apps, or any service that requires Lightning Network transactions, LNbits is a powerful, open-source solution that can be adapted to fit your project.

I'm about to have some coffee, after 14 hours not eating or drinking . I probably won't eat for a couple more hours, either.
I forgot to mention another element of Fast February: the "fiscal fast". Some of you may have heard this term before. It's exactly what it sounds like: stop spending money. In my case it just means not buying anything specifically for myself: no snacks, no takeout, no video games, etc.

2025-02-05 00:52:05Introduction: Colonization as a Multi-Generational Trauma
Colonization was not only a political and economic endeavor but also a deeply psychological one. Through forced labor, cultural erasure, and systematic oppression, colonizers imposed a set of economic and social behaviors that favored their interests. Though most colonies gained independence in the mid-20th century, the trauma of colonization remains embedded in their financial and governance structures.
Modern research in epigenetics suggests that trauma can alter gene expression and be passed down through generations (Yehuda & Lehrner, 2018). In a socio-economic context, the colonial mindset—marked by dependency, economic passivity, and a lack of financial sovereignty—persists within many post-colonial nations. One of the most insidious methods by which this trauma is maintained is through fiat currency and debt-based financial systems, which perpetuate economic dependency on former colonizers.
- The Psychological Impact of Colonial Trauma and Economic Passivity
Historical trauma theory suggests that populations subjected to prolonged oppression develop collective learned helplessness—a psychological state in which they stop attempting to resist their conditions because they have been conditioned to believe resistance is futile (Sotero, 2006).
This manifests in post-colonial societies in several ways:
-
Economic Dependency: A tendency to rely on foreign aid, multinational corporations, and foreign direct investment (FDI) rather than fostering self-sustaining industries.
-
Risk Aversion in Economic Policy: Research suggests that traumatic experiences affect the brain’s ability to take financial risks (Shields et al., 2016), leading to post-colonial states preferring IMF/World Bank solutions rather than exploring independent monetary policies.
-
Political Elite Compliance: Many former colonies' elites were educated in Western institutions, perpetuating colonial economic structures that maintain wealth extraction.
- Fiat Currency as a Tool of Economic Control
Fiat currency—money that has no intrinsic value but is backed by government decree—has been one of the most effective tools for maintaining economic dominance over former colonies.
A. The CFA Franc: A Colonial Currency in 2024
One of the most blatant examples of fiat currency maintaining colonial control is the CFA franc, used by 14 African countries, but ultimately controlled by France.
These countries must keep 50% of their foreign reserves in the French Treasury.
France dictates the monetary policies of these countries, limiting their financial autonomy.
Import dependency: Because the CFA franc is overvalued, it makes local goods more expensive while making European imports cheaper, reinforcing dependency on former colonizers.
B. The Role of the IMF and World Bank in Debt Colonialism
Post-colonial nations, lacking industrial infrastructures due to resource extraction under colonial rule, often turn to IMF and World Bank loans for development. However, these loans come with conditions that ensure neo-colonial economic control:
Structural Adjustment Programs (SAPs): Force nations to privatize industries, cut social spending, and open markets to foreign corporations—benefiting Western investors.
Perpetual Debt: Since loans are taken in foreign fiat currencies (USD, Euro), debt is rarely reduced, creating a cycle of endless repayment that prevents real economic independence.
- How Colonial Trauma Conditions Profitable Behaviors for Former Colonizers
Even outside of direct financial mechanisms, the trauma of colonization has conditioned post-colonial societies to adopt behaviors that benefit the former colonizers.
A. Elites as Gatekeepers of Colonial Structures
In many post-colonial nations, political and economic elites maintain colonial financial policies because they personally benefit from them. Studies (Acemoglu & Robinson, 2012) show that economic elites in post-colonial states are more likely to align with global financial institutions rather than advocate for economic self-determination.
B. Consumer Culture as a Neo-Colonial Tool
Western consumerism remains deeply ingrained in many post-colonial societies. This is a legacy of cultural imperialism, where local industries were suppressed in favor of Western goods.
The majority of African, South Asian, and Latin American countries continue to import Western luxury goods, technology, and services instead of developing their own.
As a result, much of the wealth generated in these countries flows back to Western corporations, mirroring the colonial economic extraction model.
Conclusion: Fiat Currency as the Modern Brand of Colonization
The economic and psychological trauma of colonization ensures that former colonies remain profitable markets and debt-ridden nations under the control of their colonizers. Fiat currency, international debt structures, and cultural hegemony serve as the modern pillars of economic colonialism, reinforcing behaviors that favor Western economic dominance.
Key Takeaways:
-
Historical trauma conditions former colonies into economic dependency.
-
Fiat currency (such as the CFA franc) remains a tool of colonial control.
-
The IMF and World Bank perpetuate financial dependency through debt cycles.
-
Consumer culture ensures wealth extraction from former colonies to Western economies.
Unless these structures are dismantled, economic sovereignty for formerly colonized nations remains an illusion. Breaking free from the financial colonial matrix requires monetary independence, de-dollarization strategies, and local industrialization, rather than continued reliance on Western financial systems.

TL;DR
This article explores the links between public, community-driven data sources (such as OpenStreetMap) and private, cryptographically-owned data found on networks such as Nostr.
The following concepts are explored:
- Attestations: Users signalling to their social graph that they believe something to be true by publishing Attestations. These social proofs act as a decentralised verification system that leverages your web-of-trust.
- Proof of Place: An oracle-based system where physical letters are sent to real-world locations, confirming the corresponding digital ownership via cryptographic proofs. This binds physical locations in meatspace with their digital representations in the Nostrverse.
- Check-ins: Foursquare-style check-ins that can be verified using attestations from place owners, ensuring authenticity. This approach uses web-of-trust to validate check-ins and location ownership over time.
The goal is to leverage cryptographic ownership where necessary while preserving the open, collaborative nature of public data systems.
Open Data in a public commons has a place and should not be thrown out with the Web 2.0 bathwater.
Cognitive Dissonance
Ever since discovering Nostr in August of 2022 I've been grappling with how BTC Map - a project that helps bitcoiners find places to spend sats - should most appropriately use this new protocol.
I am assuming, dear reader, that you are somewhat familiar with Nostr - a relatively new protocol for decentralised identity and communication. If you don’t know your nsec from your npub, please take some time to read these excellent posts: Nostr is Identity for the Internet and The Power of Nostr by @max and @lyn, respectively. Nostr is so much more than a short-form social media replacement.
The social features (check-ins, reviews, etc.) that Nostr unlocks for BTC Map are clear and exciting - all your silos are indeed broken - however, something fundamental has been bothering me for a while and I think it comes down to data ownership.
For those unfamiliar, BTC Map uses OpenStreetMap (OSM) as its main geographic database. OSM is centred on the concept of a commons of objectively verifiable data that is maintained by a global community of volunteer editors; a Wikipedia for maps. There is no data ownership; the data is free (as in freedom) and anyone can edit anything. It is the data equivalent of FOSS (Free and Open Source Software) - FOSD if you will, but more commonly referred to as Open Data.
In contrast, Notes and Other Stuff on Nostr (Places in this cartographic context) are explicitly owned by the controller of the private key. These notes are free to propagate, but they are owned.
How do we reconcile the decentralised nature of Nostr, where data is cryptographically owned by individuals, with the community-managed data commons of OpenStreetMap, where no one owns the data?
Self-sovereign Identity
Before I address this coexistence question, I want to talk a little about identity as it pertains to ownership. If something is to be owned, it has to be owned by someone or something - an identity.
All identities that are not self-sovereign are, by definition, leased to you by a 3rd party. You rent your Facebook identity from Meta in exchange for your data. You rent your web domain from your DNS provider in exchange for your money.
Taken to the extreme, you rent your passport from your Government in exchange for your compliance. You are you at the pleasure of others. Where Bitcoin separates money from the state; Nostr separates identity from the state.
Or, as @nvk said recently: "Don't build your house on someone else's land.".
https://i.nostr.build/xpcCSkDg3uVw0yku.png
While we’ve had the tools for self-sovereign digital identity for decades (think PGP keys or WebAuthN), we haven't had the necessary social use cases nor the corresponding social graph to elevate these identities to the mainstream. Nostr fixes this.
Nostr is PGP for the masses and will take cryptographic identities mainstream.
Full NOSTARD?
Returning to the coexistence question: the data on OpenStreetMap isn’t directly owned by anyone, even though the physical entities the data represents might be privately owned. OSM is a data commons.
We can objectively agree on the location of a tree or a fire hydrant without needing permission to observe and record it. Sure, you could place a tree ‘on Nostr’, but why should you? Just because something can be ‘on Nostr’ doesn’t mean it should be.
https://i.nostr.build/s3So2JVAqoY4E1dI.png
There might be a dystopian future where we can't agree on what a tree is nor where it's located, but I hope we never get there. It's at this point we'll need a Wikifreedia variant of OpenStreetMap.
While integrating Nostr identities into OpenStreetMap would be valuable, the current OSM infrastructure, tools, and community already provide substantial benefits in managing this data commons without needing to go NOSTR-native - there's no need to go Full NOSTARD. H/T to @princeySOV for the original meme.
https://i.nostr.build/ot9jtM5cZtDHNKWc.png
So, how do we appropriately blend cryptographically owned data with the commons?
If a location is owned in meatspace and it's useful to signal that ownership, it should also be owned in cyberspace. Our efforts should therefore focus on entities like businesses, while allowing the commons to manage public data for as long as it can successfully mitigate the tragedy of the commons.
The remainder of this article explores how we can:
- Verify ownership of a physical place in the real world;
- Link that ownership to the corresponding digital place in cyberspace.
As a side note, I don't see private key custodianship - or, even worse, permissioned use of Places signed by another identity's key - as any more viable than the rented identities of Web 2.0.
And as we all know, the Second Law of Infodynamics (no citation!) states that:
"The total amount of sensitive information leaked will always increase over time."
This especially holds true if that data is centralised.
Not your keys, not your notes. Not your keys, not your identity.
Places and Web-of-Trust
@Arkinox has been leading the charge on the Places NIP, introducing Nostr notes (kind 37515) that represent physical locations. The draft is well-crafted, with bonus points for linking back to OSM (and other location repositories) via NIP-73 - External Content IDs (championed by @oscar of @fountain).
However, as Nostr is permissionless, authenticity poses a challenge. Just because someone claims to own a physical location on the Internet doesn’t necessarily mean they have ownership or control of that location in the real world.
Ultimately, this problem can only be solved in a decentralised way by using Web-of-Trust - using your social graph and the perspectives of trusted peers to inform your own perspective. In the context of Places, this requires your network to form a view on which digital identity (public key / npub) is truly the owner of a physical place like your local coffee shop.
This requires users to:
- Verify the owner of a Place in cyberspace is the owner of a place in meatspace.
- Signal this verification to their social graph.
Let's look at the latter idea first with the concept of Attestations ...
Attestations
A way to signal to your social graph that you believe something to be true (or false for that matter) would be by publishing an Attestation note. An Attestation note would signify to your social graph that you think something is either true or false.
Imagine you're a regular at a local coffee shop. You publish an Attestation that says the shop is real and the owner behind the Nostr public key is who they claim to be. Your friends trust you, so they start trusting the shop's digital identity too.
However, attestations applied to Places are just a single use case. The attestation concept could be more widely applied across Nostr in a variety of ways (key rotation, identity linking, etc).
Here is a recent example from @lyn that would carry more signal if it were an Attestation:
https://i.nostr.build/lZAXOEwvRIghgFY4.png
Parallels can be drawn between Attestations and transaction confirmations on the Bitcoin timechain; however, their importance to you would be weighted by clients and/or Data Vending Machines in accordance with:
- Your social graph;
- The type or subject of the content being attested and by whom;
- Your personal preferences.
They could also have a validity duration to be temporally bound, which would be particularly useful in the case of Places.
NIP-25 (Reactions) do allow for users to up/downvote notes with optional content (e.g., emojis) and could work for Attestations, but I think we need something less ambiguous and more definitive.
‘This is true’ resonates more strongly than ‘I like this.’.
https://i.nostr.build/s8NIG2kXzUCLcoax.jpg
There are similar concepts in the Web 3 / Web 5 world such as Verified Credentials by tdb. However, Nostr is the Web 3 now and so wen Attestation NIP?
https://i.nostr.build/Cb047NWyHdJ7h5Ka.jpg
That said, I have seen @utxo has been exploring ‘smart contracts’ on nostr and Attestations may just be a relatively ‘dumb’ subset of the wider concept Nostr-native scripting combined with web-of-trust.
Proof of Place
Attestations handle the signalling of your truth, but what about the initial verification itself?
We already covered how this ultimately has to be derived from your social graph, but what if there was a way to help bootstrap this web-of-trust through the use of oracles? For those unfamiliar with oracles in the digital realm, they are simply trusted purveyors of truth.
Introducing Proof of Place, an out–of-band process where an oracle (such as BTC Map) would mail - yes physically mail- a shared secret to the address of the location being claimed in cyberspace. This shared secret would be locked to the public key (npub) making the claim, which, if unlocked, would prove that the associated private key (nsec) has physical access to the location in meatspace.
One way of doing this would be to mint a 1 sat cashu ecash token locked to the npub of the claimant and mail it to them. If they are able to redeem the token then they have cryptographically proven that they have physical access to the location.
Proof of Place is really nothing more than a weighted Attestation. In a web-of-trust Nostrverse, an oracle is simply a npub (say BTC Map) that you weigh heavily for its opinion on a given topic (say Places).
In the Bitcoin world, Proof of Work anchors digital scarcity in cyberspace to physical scarcity (energy and time) in meatspace and as @Gigi says in PoW is Essential:
"A failure to understand Proof of Work, is a failure to understand Bitcoin."
In the Nostrverse, Proof of Place helps bridge the digital and physical worlds.
@Gigi also observes in Memes vs The World that:
"In Bitcoin, the map is the territory. We can infer everything we care about by looking at the map alone."
https://i.nostr.build/dOnpxfI4u7EL2v4e.png
This isn’t true for Nostr.
In the Nostrverse, the map IS NOT the territory. However, Proof of Place enables us to send cryptographic drones down into the physical territory to help us interpret our digital maps. 🤯
Check-ins
Although not a draft NIP yet, @Arkinox has also been exploring the familiar concept of Foursquare-style Check-ins on Nostr (with kind 13811 notes).
For the uninitiated, Check-ins are simply notes that signal the publisher is at a given location. These locations could be Places (in the Nostr sense) or any other given digital representation of a location for that matter (such as OSM elements) if NIP-73 - External Content IDs are used.
Of course, not everyone will be a Check-in enjoyooor as the concept will not sit well with some people’s threat models and OpSec practices.
Bringing Check-ins to Nostr is possible (as @sebastix capably shows here), but they suffer the same authenticity issues as Places. Just because I say I'm at a given location doesn't mean that I am.
Back in the Web 2.0 days, Foursquare mitigated this by relying on the GPS position of the phone running their app, but this is of course spoofable.
How should we approach Check-in verifiability in the Nostrverse? Well, just like with Places, we can use Attestations and WoT. In the context of Check-ins, an Attestation from the identity (npub) of the Place being checked-in to would be a particularly strong signal. An NFC device could be placed in a coffee shop and attest to check-ins without requiring the owner to manually intervene - I’m sure @blackcoffee and @Ben Arc could hack something together over a weekend!
Check-ins could also be used as a signal for bonafide Place ownership over time.
Summary: Trust Your Bros
So, to recap, we have:
Places: Digital representations of physical locations on Nostr.
Check-ins: Users signalling their presence at a location.
Attestations: Verifiable social proofs used to confirm ownership or the truth of a claim.
You can visualise how these three concepts combine in the diagram below:
https://i.nostr.build/Uv2Jhx5BBfA51y0K.jpg
And, as always, top right trumps bottom left! We have:
Level 0 - Trust Me Bro: Anyone can check-in anywhere. The Place might not exist or might be impersonating the real place in meatspace. The person behind the npub may not have even been there at all.
Level 1 - Definitely Maybe Somewhere: This category covers the middle-ground of ‘Maybe at a Place’ and ‘Definitely Somewhere’. In these examples, you are either self-certifying that you have checked-in at an Attested Place or you are having others attest that you have checked-in at a Place that might not even exist IRL.
Level 2 - Trust Your Bros: An Attested Check-in at an Attested Place. Your individual level of trust would be a function of the number of Attestations and how you weigh them within your own social graph.
https://i.nostr.build/HtLAiJH1uQSTmdxf.jpg
Perhaps the gold standard (or should that be the Bitcoin standard?) would be a Check-in attested by the owner of the Place, which in itself was attested by BTC Map?
Or perhaps not. Ultimately, it’s the users responsibility to determine what they trust by forming their own perspective within the Nostrverse powered by web-of-trust algorithms they control. ‘Trust Me Bro’ or ‘Trust Your Bros’ - you decide.
As we navigate the frontier of cryptographic ownership and decentralised data, it’s up to us to find the balance between preserving the Open Data commons and embracing self-sovereign digital identities.
Thanks

2025-02-02 13:09:27We’re thrilled to announce the stable release of Cashu-TS v2.2! Although this update is a minor version bump, it brings significant improvements under the hood that enhance the overall developer experience. We’ve spent several weeks testing and refining these changes.
What’s New in v2.2?
While there are no breaking changes in this release, there are many internal changes. If you spot any regressions or unexpected behavior, please let us know. Here’s a rundown of the major updates:
- Enhanced Proof Creation: The way proofs are created internally has been revamped.
- User-Controlled Outputs: You now have full control over how outputs are created.
- Improved Bundling: We’ve switched our bundling tool to vite for faster and more modern builds.
- Updated Testing Tools: Our testing framework has migrated to vitest and msw, with added browser testing via Playwright.
New Flexibility with OutputData
In previous versions of Cashu-TS, the creation of outputs (or BlindedMessages) was hidden away. Even though there were options to tweak the process (like deterministic secrets or P2PK), you were always limited to the built-in logic.
What’s Changed?
In v2.2, we’ve introduced a public interface that not only streamlines output creation but also lets you plug in your own custom logic when needed. With the new
outputData
option available on all output-creating methods, you can now bypass the automatic process and provide your own outputs.For example, you can create two proofs tied to different public keys in a single mint operation:
ts const data1 = OutputData.createP2PKData({ pubkey: "key1" }, 10, keys); const data2 = OutputData.createP2PKData({ pubkey: "key2" }, 10, keys); const { keep, send } = await wallet.send(20, proofs, { outputData: { send: [...data1, ...data2] }, });
Customization Made Easy
The
outputData
option now accepts anything that conforms to theOutputDataLike
interface. This means you can introduce your own output creation logic—even if it’s not natively supported by Cashu-TS yet. Here’s what the interface looks like:```ts export interface OutputDataLike { blindedMessage: SerializedBlindedMessage; blindingFactor: bigint; secret: Uint8Array;
toProof: (signature: SerializedBlindedSignature, keyset: MintKeys) => Proof; } ```
Introducing OutputData Factories
While having full control is empowering, it also means you’ll need to handle tasks like fee calculation and amount selection manually. To strike a balance between control and convenience, we now support OutputData Factories.
A factory is simply a function that takes an amount and
MintKeys
as input and returns anOutputDataLike
object. This way, you can define a blueprint for your output data without worrying about the nitty-gritty details. For instance, you can create separate factories for amounts you keep versus those you send:```ts function keepFactory(a: number, k: MintKeys) { return OutputData.createSingleP2PKData({ pubkey: "keepPk" }, a, k.id); }
function sendFactory(a: number, k: MintKeys) { return OutputData.createSingleP2PKData({ pubkey: "sendPk" }, a, k.id); }
const { send, keep } = await wallet.send(amount, proofs, { outputData: { send: createFactory("send"), keep: createFactory("keep") }, }); ```
Plus, you can now instantiate a
CashuWallet
with a defaultkeepFactory
, ensuring that all change amounts automatically lock to your key—streamlining your workflow even further.
Bundling Improvements with Vite
Starting with v2.2, we’ve transitioned from using
tsc
to vite for transpiling and bundling the library code. Although this change is mostly behind the scenes, it brings several benefits:- Modern Build Target: We’ve updated our build target to ES6.
- Updated Exports: The package exports now reflect the latest JavaScript standards.
- Standalone Build Soon: We’re working on a standalone build that bundles Cashu-TS along with all its dependencies. This will let you import Cashu-TS directly into your HTML.
If you encounter any issues with the new bundling setup, please let us know.
A Nod to Vitest
In addition to our bundling improvements, we’ve migrated our testing framework from Jest (with nock) to vitest combined with msw. This switch gives us more flexibility in testing and mocking, plus we’ve added browser testing based on Playwright—thanks to the tip from nostr:npub16anjdksmvn5x08vtden04n64rw5k7fsjmedpw8avsx8wsh8ruhlq076pfx!
In Conclusion
Although Cashu-TS v2.2 is a minor version update, it comes packed with improvements that enhance both the developer experience and the flexibility of the library. We’re excited to see how you’ll use these new features in your projects! Thanks to all the amazing contributors that add to this library.
Thank you for being a part of the Cashu-TS community. As always, if you have any questions, suggestions, or issues, don’t hesitate to reach out to us.

2025-02-05 00:14:34Welcome to the first installment of my ‘Nostr Spotlight’, a series where I explore various Nostr clients (which I will refer to as apps for simplicity sake), review their features, and share tips on how to use them effectively.
For the first installment, I’m diving into npub.pro, an incredible service that lets anyone on Nostr create a fully functional website using their already-published notes.
What is npub.pro?
npub.pro is a simple—yet powerful— tool that takes your Nostr content and turns it into a website instantly. By filtering through hashtags or keywords, or hand-selecting which notes to feature, you can curate what appears on your site.
This allows for highly customizable and dynamic websites that anyone on Nostr can deploy. Whether you’re a blogger, photographer, journalist, artist—or just want to organize your notes into a cleanly setup website—this service opens up endless possibilities for showcasing your notes.
Who Should Use npub.pro?
This service is ideal for:
✅ Writers and bloggers who want a frictionless way to publish content.
✅ Artists and photographers looking to showcase their work.
✅ Journalists and researchers who need an easy way to organize articles.
✅ Anyone who wants a personal website without dealing with hosting or technical setups.
Why I Love npub.pro
I’ve personally deployed several websites using npub.pro, each serving a different purpose:
HesArt – My personal art portfolio.

2024-10-23 20:26:10Herzlichen Glückwunsch zum dritten Geburtstag, liebe Denk Bar! Wieso zum dritten? Das war doch 2022 und jetzt sind wir im Jahr 2024, oder? Ja, das ist schon richtig, aber bei Geburtstagen erinnere ich mich immer auch an meinen Vater, und der behauptete oft, der erste sei ja schließlich der Tag der Geburt selber und den müsse man natürlich mitzählen. Wo er recht hat, hat er nunmal recht. Konsequenterweise wird also heute dieser Blog an seinem dritten Geburtstag zwei Jahre alt.
Das ist ein Grund zum Feiern, wie ich finde. Einerseits ganz einfach, weil es dafür gar nicht genug Gründe geben kann. «Das Leben sind zwei Tage», lautet ein gängiger Ausdruck hier in Andalusien. In der Tat könnte es so sein, auch wenn wir uns im Alltag oft genug von der Routine vereinnahmen lassen.
Seit dem Start der Denk Bar vor zwei Jahren ist unglaublich viel passiert. Ebenso wie die zweieinhalb Jahre davor, und all jenes war letztlich auch der Auslöser dafür, dass ich begann, öffentlich zu schreiben. Damals notierte ich:
«Seit einigen Jahren erscheint unser öffentliches Umfeld immer fragwürdiger, widersprüchlicher und manchmal schier unglaublich - jede Menge Anlass für eigene Recherchen und Gedanken, ganz einfach mit einer Portion gesundem Menschenverstand.»
Wir erleben den sogenannten «großen Umbruch», einen globalen Coup, den skrupellose Egoisten clever eingefädelt haben und seit ein paar Jahren knallhart – aber nett verpackt – durchziehen, um buchstäblich alles nach ihrem Gusto umzukrempeln. Die Gelegenheit ist ja angeblich günstig und muss genutzt werden.
Nie hätte ich mir träumen lassen, dass ich so etwas jemals miterleben müsste. Die Bosheit, mit der ganz offensichtlich gegen die eigene Bevölkerung gearbeitet wird, war früher für mich unvorstellbar. Mein (Rest-) Vertrauen in alle möglichen Bereiche wie Politik, Wissenschaft, Justiz, Medien oder Kirche ist praktisch komplett zerstört. Einen «inneren Totalschaden» hatte ich mal für unsere Gesellschaften diagnostiziert.
Was mich vielleicht am meisten erschreckt, ist zum einen das Niveau der Gleichschaltung, das weltweit erreicht werden konnte, und zum anderen die praktisch totale Spaltung der Gesellschaft. Haben wir das tatsächlich mit uns machen lassen?? Unfassbar! Aber das Werkzeug «Angst» ist sehr mächtig und funktioniert bis heute.
Zum Glück passieren auch positive Dinge und neue Perspektiven öffnen sich. Für viele Menschen waren und sind die Entwicklungen der letzten Jahre ein Augenöffner. Sie sehen «Querdenken» als das, was es ist: eine Tugend.
Auch die immer ernsteren Zensurbemühungen sind letztlich nur ein Zeichen der Schwäche, wo Argumente fehlen. Sie werden nicht verhindern, dass wir unsere Meinung äußern, unbequeme Fragen stellen und dass die Wahrheit peu à peu ans Licht kommt. Es gibt immer Mittel und Wege, auch für uns.
Danke, dass du diesen Weg mit mir weitergehst!

2024-10-19 08:58:08Ein Lämmchen löschte an einem Bache seinen Durst. Fern von ihm, aber näher der Quelle, tat ein Wolf das gleiche. Kaum erblickte er das Lämmchen, so schrie er:
"Warum trübst du mir das Wasser, das ich trinken will?"
"Wie wäre das möglich", erwiderte schüchtern das Lämmchen, "ich stehe hier unten und du so weit oben; das Wasser fließt ja von dir zu mir; glaube mir, es kam mir nie in den Sinn, dir etwas Böses zu tun!"
"Ei, sieh doch! Du machst es gerade, wie dein Vater vor sechs Monaten; ich erinnere mich noch sehr wohl, daß auch du dabei warst, aber glücklich entkamst, als ich ihm für sein Schmähen das Fell abzog!"
"Ach, Herr!" flehte das zitternde Lämmchen, "ich bin ja erst vier Wochen alt und kannte meinen Vater gar nicht, so lange ist er schon tot; wie soll ich denn für ihn büßen."
"Du Unverschämter!" so endigt der Wolf mit erheuchelter Wut, indem er die Zähne fletschte. "Tot oder nicht tot, weiß ich doch, daß euer ganzes Geschlecht mich hasset, und dafür muß ich mich rächen."
Ohne weitere Umstände zu machen, zerriß er das Lämmchen und verschlang es.
Das Gewissen regt sich selbst bei dem größten Bösewichte; er sucht doch nach Vorwand, um dasselbe damit bei Begehung seiner Schlechtigkeiten zu beschwichtigen.

2025-02-04 08:29:00President Trump has started rolling out his tariffs, something I blogged about in November. People are talking about these tariffs a lot right now, with many people (correctly) commenting on how consumers will end up with higher prices as a result of these tariffs. While that part is true, I’ve seen a lot of people taking it to the next, incorrect step: that consumers will pay the entirety of the tax. I put up a poll on X to see what people thought, and while the right answer got a lot of votes, it wasn't the winner.
For purposes of this blog post, our ultimate question will be the following:
- Suppose apples currently sell for $1 each in the entire United States.
- There are domestic sellers and foreign sellers of apples, all receiving the same price.
- There are no taxes or tariffs on the purchase of apples.
- The question is: if the US federal government puts a $0.50 import tariff per apple, what will be the change in the following:
- Number of apples bought in the US
- Price paid by buyers for apples in the US
- Post-tax price received by domestic apple producers
- Post-tax price received by foreign apple producers
Before we can answer that question, we need to ask an easier, first question: before instituting the tariff, why do apples cost $1?
And finally, before we dive into the details, let me provide you with the answers to the ultimate question. I recommend you try to guess these answers before reading this, and if you get it wrong, try to understand why:
- The number of apples bought will go down
- The buyers will pay more for each apple they buy, but not the full amount of the tariff
- Domestic apple sellers will receive a higher price per apple
- Foreign apple sellers will receive a lower price per apple, but not lowered by the full amount of the tariff
In other words, regardless of who sends the payment to the government, both taxed parties (domestic buyers and foreign sellers) will absorb some of the costs of the tariff, while domestic sellers will benefit from the protectionism provided by tariffs and be able to sell at a higher price per unit.
Marginal benefit
All of the numbers discussed below are part of a helper Google Sheet I put together for this analysis. Also, apologies about the jagged lines in the charts below, I hadn’t realized before starting on this that there are some difficulties with creating supply and demand charts in Google Sheets.
Let’s say I absolutely love apples, they’re my favorite food. How much would I be willing to pay for a single apple? You might say “$1, that’s the price in the supermarket,” and in many ways you’d be right. If I walk into supermarket A, see apples on sale for $50, and know that I can buy them at supermarket B for $1, I’ll almost certainly leave A and go buy at B.
But that’s not what I mean. What I mean is: how high would the price of apples have to go everywhere so that I’d no longer be willing to buy a single apple? This is a purely personal, subjective opinion. It’s impacted by how much money I have available, other expenses I need to cover, and how much I like apples. But let’s say the number is $5.
How much would I be willing to pay for another apple? Maybe another $5. But how much am I willing to pay for the 1,000th apple? 10,000th? At some point, I’ll get sick of apples, or run out of space to keep the apples, or not be able to eat, cook, and otherwise preserve all those apples before they rot.
The point being: I’ll be progressively willing to spend less and less money for each apple. This form of analysis is called marginal benefit: how much benefit (expressed as dollars I’m willing to spend) will I receive from each apple? This is a downward sloping function: for each additional apple I buy (quantity demanded), the price I’m willing to pay goes down. This is what gives my personal demand curve. And if we aggregate demand curves across all market participants (meaning: everyone interested in buying apples), we end up with something like this:
Assuming no changes in people’s behavior and other conditions in the market, this chart tells us how many apples will be purchased by our buyers at each price point between $0.50 and $5. And ceteris paribus (all else being equal), this will continue to be the demand curve for apples.
Marginal cost
Demand is half the story of economics. The other half is supply, or: how many apples will I sell at each price point? Supply curves are upward sloping: the higher the price, the more a person or company is willing and able to sell a product.
Let’s understand why. Suppose I have an apple orchard. It’s a large property right next to my house. With about 2 minutes of effort, I can walk out of my house, find the nearest tree, pick 5 apples off the tree, and call it a day. 5 apples for 2 minutes of effort is pretty good, right?
Yes, there was all the effort necessary to buy the land, and plant the trees, and water them… and a bunch more than I likely can’t even guess at. We’re going to ignore all of that for our analysis, because for short-term supply-and-demand movement, we can ignore these kinds of sunk costs. One other simplification: in reality, supply curves often start descending before ascending. This accounts for achieving efficiencies of scale after the first number of units purchased. But since both these topics are unneeded for understanding taxes, I won’t go any further.
Anyway, back to my apple orchard. If someone offers me $0.50 per apple, I can do 2 minutes of effort and get $2.50 in revenue, which equates to a $75/hour wage for me. I’m more than happy to pick apples at that price!
However, let’s say someone comes to buy 10,000 apples from me instead. I no longer just walk out to my nearest tree. I’m going to need to get in my truck, drive around, spend the day in the sun, pay for gas, take a day off of my day job (let’s say it pays me $70/hour). The costs go up significantly. Let’s say it takes 5 days to harvest all those apples myself, it costs me $100 in fuel and other expenses, and I lose out on my $70/hour job for 5 days. We end up with:
- Total expenditure: $100 + $70 * 8 hours a day * 5 days \== $2900
- Total revenue: $5000 (10,000 apples at $0.50 each)
- Total profit: $2100
So I’m still willing to sell the apples at this price, but it’s not as attractive as before. And as the number of apples purchased goes up, my costs keep increasing. I’ll need to spend more money on fuel to travel more of my property. At some point I won’t be able to do the work myself anymore, so I’ll need to pay others to work on the farm, and they’ll be slower at picking apples than me (less familiar with the property, less direct motivation, etc.). The point being: at some point, the number of apples can go high enough that the $0.50 price point no longer makes me any money.
This kind of analysis is called marginal cost. It refers to the additional amount of expenditure a seller has to spend in order to produce each additional unit of the good. Marginal costs go up as quantity sold goes up. And like demand curves, if you aggregate this data across all sellers, you get a supply curve like this:
Equilibrium price
We now know, for every price point, how many apples buyers will purchase, and how many apples sellers will sell. Now we find the equilibrium: where the supply and demand curves meet. This point represents where the marginal benefit a buyer would receive from the next buyer would be less than the cost it would take the next seller to make it. Let’s see it in a chart:
You’ll notice that these two graphs cross at the $1 price point, where 63 apples are both demanded (bought by consumers) and supplied (sold by producers). This is our equilibrium price. We also have a visualization of the surplus created by these trades. Everything to the left of the equilibrium point and between the supply and demand curves represents surplus: an area where someone is receiving something of more value than they give. For example:
- When I bought my first apple for $1, but I was willing to spend $5, I made $4 of consumer surplus. The consumer portion of the surplus is everything to the left of the equilibrium point, between the supply and demand curves, and above the equilibrium price point.
- When a seller sells his first apple for $1, but it only cost $0.50 to produce it, the seller made $0.50 of producer surplus. The producer portion of the surplus is everything to the left of the equilibrium point, between the supply and demand curves, and below the equilibrium price point.
Another way of thinking of surplus is “every time someone got a better price than they would have been willing to take.”
OK, with this in place, we now have enough information to figure out how to price in the tariff, which we’ll treat as a negative externality.
Modeling taxes
Alright, the government has now instituted a $0.50 tariff on every apple sold within the US by a foreign producer. We can generally model taxes by either increasing the marginal cost of each unit sold (shifting the supply curve up), or by decreasing the marginal benefit of each unit bought (shifting the demand curve down). In this case, since only some of the producers will pay the tax, it makes more sense to modify the supply curve.
First, let’s see what happens to the foreign seller-only supply curve when you add in the tariff:
With the tariff in place, for each quantity level, the price at which the seller will sell is $0.50 higher than before the tariff. That makes sense: if I was previously willing to sell my 82nd apple for $3, I would now need to charge $3.50 for that apple to cover the cost of the tariff. We see this as the tariff “pushing up” or “pushing left” the original supply curve.
We can add this new supply curve to our existing (unchanged) supply curve for domestic-only sellers, and we end up with a result like this:
The total supply curve adds up the individual foreign and domestic supply curves. At each price point, we add up the total quantity each group would be willing to sell to determine the total quantity supplied for each price point. Once we have that cumulative supply curve defined, we can produce an updated supply-and-demand chart including the tariff:
As we can see, the equilibrium has shifted:
- The equilibrium price paid by consumers has risen from $1 to $1.20.
- The total number of apples purchased has dropped from 63 apples to 60 apples.
- Consumers therefore received 3 less apples. They spent $72 for these 60 apples, whereas previously they spent $63 for 3 more apples, a definite decrease in consumer surplus.
- Foreign producers sold 36 of those apples (see the raw data in the linked Google Sheet), for a gross revenue of $43.20. However, they also need to pay the tariff to the US government, which accounts for $18, meaning they only receive $25.20 post-tariff. Previously, they sold 42 apples at $1 each with no tariff to be paid, meaning they took home $42.
- Domestic producers sold the remaining 24 apples at $1.20, giving them a revenue of $28.80. Since they don’t pay the tariff, they take home all of that money. By contrast, previously, they sold 21 apples at $1, for a take-home of $21.
- The government receives $0.50 for each of the 60 apples sold, or in other words receives $30 in revenue it wouldn’t have received otherwise.
We could be more specific about the surpluses, and calculate the actual areas for consumer surplus, producer surplus, inefficiency from the tariff, and government revenue from the tariff. But I won’t bother, as those calculations get slightly more involved. Instead, let’s just look at the aggregate outcomes:
- Consumers were unquestionably hurt. Their price paid went up by $0.20 per apple, and received less apples.
- Foreign producers were also hurt. Their price received went down from the original $1 to the new post-tariff price of $1.20, minus the $0.50 tariff. In other words: foreign producers only receive $0.70 per apple now. This hurt can be mitigated by shifting sales to other countries without a tariff, but the pain will exist regardless.
- Domestic producers scored. They can sell less apples and make more revenue doing it.
- And the government walked away with an extra $30.
Hopefully you now see the answer to the original questions. Importantly, while the government imposed a $0.50 tariff, neither side fully absorbed that cost. Consumers paid a bit more, foreign producers received a bit less. The exact details of how that tariff was split across the groups is mediated by the relevant supply and demand curves of each group. If you want to learn more about this, the relevant search term is “price elasticity,” or how much a group’s quantity supplied or demanded will change based on changes in the price.
Other taxes
Most taxes are some kind of a tax on trade. Tariffs on apples is an obvious one. But the same applies to income tax (taxing the worker for the trade of labor for money) or payroll tax (same thing, just taxing the employer instead). Interestingly, you can use the same model for analyzing things like tax incentives. For example, if the government decided to subsidize domestic apple production by giving the domestic producers a $0.50 bonus for each apple they sell, we would end up with a similar kind of analysis, except instead of the foreign supply curve shifting up, we’d see the domestic supply curve shifting down.
And generally speaking, this is what you’ll always see with government involvement in the economy. It will result in disrupting an existing equilibrium, letting the market readjust to a new equilibrium, and incentivization of some behavior, causing some people to benefit and others to lose out. We saw with the apple tariff, domestic producers and the government benefited while others lost.
You can see the reverse though with tax incentives. If I give a tax incentive of providing a deduction (not paying income tax) for preschool, we would end up with:
- Government needs to make up the difference in tax revenue, either by raising taxes on others or printing more money (leading to inflation). Either way, those paying the tax or those holding government debased currency will pay a price.
- Those people who don’t use the preschool deduction will receive no benefit, so they simply pay a cost.
- Those who do use the preschool deduction will end up paying less on tax+preschool than they would have otherwise.
This analysis is fully amoral. It’s not saying whether providing subsidized preschool is a good thing or not, it simply tells you where the costs will be felt, and points out that such government interference in free economic choice does result in inefficiencies in the system. Once you have that knowledge, you’re more well educated on making a decision about whether the costs of government intervention are worth the benefits.

2024-05-09 17:23:28Lot of people are starting to talk about building a web-of-trust and how nostr can or is already being used as such
We all know about using the kind:3 following lists as a simple WoT that can be used to filter out spam. but as we all know it does not really signal "trust", its mostly just "I find your content interesting"
But what about real "trust"... well its kind of multi-denominational, I could trust that your a good developer or a good journalist but still not trust you enough to invite you over to my house. There are some interesting and clever solutions proposed for quantifying "trust" in a digital sense but I'm not going to get into that here. I want to talk about something that I have not see anyone discuss yet.
How is the web-of-trust maintained? or more precisely how do you expect users to update the digital representation of the "trust" of other users?
Its all well and good to think of how a user would create that "trust" of another user when discovering them for the first time. They would click the "follow" button, or maybe even rate them on a few topics with a 1/5 star system But how will a user remove that trust? how will they update it if things change and they trust them less?
If our goal is to model "trust" in a digital sense then we NEED a way for the data to stay up-to-date and as accurate as possible. otherwise whats the use? If we don't have a friction-less way to update or remove the digital representation of "trust" then we will end up with a WoT that continuously grows and everyone is rated 10/10
In the case of nostr kind:3 following lists. its pretty easy to see how these would get updated. If someone posts something I dislike or I notice I'm getting board of their content. then I just unfollow them. An important part here is that I'm not thinking "I should update my trust score of this user" but instead "I'm no longer interested, I don't want to see this anymore"
But that is probably the easiest "trust" to update. because most of us on social media spend some time curating our feed and we are used to doing it. But what about the more obscure "trust" scores? whats the regular mechanism by which a user would update the "honestly" score of another user?
In the real world its easy, when I stop trusting someone I simply stop associating with them. there isn't any button or switch I need to update. I simply don't talk to them anymore, its friction-less But in the digital realm I would have to remove or update that trust. in other words its an action I need to take instead of an action I'm not doing. and actions take energy.
So how do we reflect something in the digital world that takes no-energy and is almost subconscious in the real world?
TLDR; webs-of-trust are not just about scoring other users once. you must keep the score up-to-date

2025-01-22 20:48:34Background
Most people non familiar with Bitcoin thinks that there its has not smart contracts capabilities, and that is incorrect, there are smart contract capabilities, and despite limited in comparison with other blockchain networks, those capabilities are evolving slowly but surely.
The support for smart contracts is done through its scripting language, Script, which allows developers to create complex conditions for transactions.
What can you do with Script? 1. time locks 2. multi-signature requirements 3. other custom logic
opcodes like OP_CHECKLOCKTIMEVERIFY (CLTV) and OP_CHECKSEQUENCEVERIFY (CSV) are used to build more sophisticated smart contracts, these opcodes enable features such as the Lightning Network, a key scaling solution for Bitcoin
back in 2021, the Taproot upgrade introduced Pay-to-Taproot (P2TR), in summary allows for more private and efficient smart contracts, in that soft fork more was added, in addition to Taproot, we got as well Schnorr signatures, which enables multiple signatures to be aggregated into a single signature, improving scalability and privacy and MAST (Merklized Abstract Syntax Trees) which reduces the size of complex smart contracts, making them more efficient, as an added value, this efficiency reduces the cost of transactions.
The Taproot upgrade has laid the foundation for the development of more sophisticated smart contracts on the Bitcoin network, and the use of covenants is an important part of this development.
What is Bitcoin Covenants?
It is a BIP (Bitcoin Improvement Proposal), BIP-347, assigned on April 24, 2024, which marks the first step towards reintroducing functionality removed from Bitcoin by its creator Satoshi Nakamoto in 2010. This proposal aims to bring smart contract functionality to Bitcoin as we see in other EVM networks.
The proposal’s developers authors names are Ethan Heilman and Armin Sabouri, now the community will debate its merits.
Here the link, in case you are curious:
https://github.com/bitcoin/bips/blob/master/bip-0347.mediawiki
It is worth to read the motivation section of the BIP, which reads:
“Bitcoin Tapscript lacks a general purpose way of combining objects on the stack, restricting the expressiveness and power of Tapscript. This prevents, among many other things, the ability to construct and evaluate merkle trees and other hashed data structures in Tapscript. OP_CAT, by adding a general purpose way to concatenate stack values, would overcome this limitation and greatly increase the functionality of Tapscript.
OP_CAT aims to expand the toolbox of the tapscript developer with a simple, modular, and useful opcode in the spirit of Unix. To demonstrate the usefulness of OP_CAT below we provide a non-exhaustive list of some use cases that OP_CAT would enable:
Bitstream, a protocol for the atomic swap (fair exchange) of bitcoins for decryption keys, that enables decentralized file hosting systems paid in Bitcoin. While such swaps are currently possible on Bitcoin without OP_CAT, they require the use of complex and computationally expensive Verifiable Computation cryptographic techniques. OP_CAT would remove this requirement on Verifiable Computation, making such protocols far more practical to build in Bitcoin.
Tree signatures provide a multisignature script whose size can be logarithmic in the number of public keys and can encode spend conditions beyond n-of-m. For instance a transaction less than 1KB in size could support tree signatures with up to 4,294,967,296 public keys. This also enables generalized logical spend conditions.
Post-Quantum Lamport signatures in Bitcoin transactions. Lamport signatures merely require the ability to hash and concatenate values on the stack. [4] It has been proposed that if ECDSA is broken or a powerful computer was on the horizon, there might be an effort to protect ownership of bitcoins by allowing people to mark their taproot outputs as "script-path only" and then move their coins into such outputs with a leaf in the script tree requiring a Lamport signature. It is an open question if a tapscript commitment would preserve the quantum resistance of Lamport signatures. Beyond this question, the use of Lamport Signatures in taproot outputs is unlikely to be quantum resistant even if the script spend-path is made quantum resistant. This is because taproot outputs can also be spent with a key. An attacker with a sufficiently powerful quantum computer could bypass the taproot script spend-path by finding the discrete log of the taproot output and thus spending the output using the key spend-path. The use of "Nothing Up My Sleeve" (NUMS) points as described in BIP-341 to disable the key spend-path does not disable the key spend-path against a quantum attacker as NUMS relies on the hardness of finding discrete logs. We are not aware of any mechanism which could disable the key spend-path in a taproot output without a soft-fork change to taproot.
Non-equivocation contracts in tapscript provide a mechanism to punish equivocation/double spending in Bitcoin payment channels. OP_CAT enables this by enforcing rules on the spending transaction's nonce. The capability is a useful building block for payment channels and other Bitcoin protocols.
Vaults [6] which are a specialized covenant that allows a user to block a malicious party who has compromised the user's secret key from stealing the funds in that output. As shown in OP_CAT is sufficient to build vaults in Bitcoin.
Replicating CheckSigFromStack which would allow the creation of simple covenants and other advanced contracts without having to pre-sign spending transactions, possibly reducing complexity and the amount of data that needs to be stored. Originally shown to work with Schnorr signatures, this result has been extended to ECDSA signatures.
OP_CAT was available in early versions of Bitcoin. In 2010, a single commit disabled OP_CAT, along with another 15 opcodes. Folklore states that OP_CAT was removed in this commit because it enabled the construction of a script whose evaluation could have memory usage exponential in the size of the script. For example, a script that pushed a 1-byte value on the stack and then repeated the opcodes OP_DUP, OP_CAT 40 times would result in a stack element whose size was greater than 1 terabyte assuming no maximum stack element size. As Bitcoin at that time had a maximum stack element size of 5000 bytes, the effect of this expansion was limited to 5000 bytes. This is no longer an issue because tapscript enforces a maximum stack element size of 520 bytes.”
The last update of the BIP was done on Sep. 8 2024 by Ethan Heilman
Controversy
The controversy revolves around two main camps:
- Those who want to preserve Bitcoin’s network for monetary transactions only, arguing that adding smart contract capabilities could introduce risks and complexity.
- Others who advocate for expanding Bitcoin’s capabilities to support a wider range of applications, seeing OP_CAT as a step towards enhancing the network’s utility.
Final Thoughts
Bitcoin have done what no other asset have done in history, neither gold, its success is clear, and now, that BlackRock is involved, “miraculously”, corporations and governments are getting on board and Bitcoin is not anymore only for criminals or “rat poison” or “is going to zero”.
But as all tech, improvements are important, if those improvements are done to secure more the network and to make it more robust, there will be little to none controversy, however, when those changes are aiming at adding new shinning features that would change Bitcoin into a network with similar features as Ethereum in terms of contracts that requires attention and debate, few questions come to mind:
- How will that change affect the security of the network?
- How that change will affect the blockchain usage?
- What is the projected impact over the fees per transaction if this change is approved?
- Will the impact create pressure for the block size increase discussion to come back to the table and with it a second war?
Looking into Ethan Heilman work and contribution to the Bitcoin ecosystem, I am inclined to believe that he has considered most of those questions.
Looking forward to observe the evolution of this proposal.

2024-01-30 20:06:18Güneşin kaybolmasının üçüncü günü, saat öğlen on ikiyi yirmi geçiyordu. Trenin kalkmasına yaklaşık iki saat vardı. Hepimiz perondaydık. Valizlerimiz, kolilerimiz, renk renk ve biçimsiz çantalarımızla yan yana dizilmiş, kısa aralıklarla tepemizdeki devasa saati kontrol ediyorduk.
Ama ne kadar dik bakarsak bakalım zaman bir türlü istediğimiz hızla ilerlemiyordu. Herkes birkaç dakika sürmesi gereken alelade bir doğa olayına sıkışıp kalmış, karanlıktan sürünerek çıkmayı deniyordu.
Bekleme salonuna doğru döndüm. Nefesimden çıkan buharın arkasında, kalın taş duvarları ve camlarıyla morg kadar güvenli ve soğuk duruyordu. Cesetleri o yüzden bunun gibi yerlere taşımaya başlamışlardı. Demek insanların bütün iyiliği başkaları onları gördüğü içindi ki gündüzleri gecelerden daha karanlık olduğunda hemen birbirlerinin gırtlağına çökmüş, böğürlerinde delikler açmış, gözlerini oyup kafataslarını parçalamışlardı.
İstasyonun ışığı titrediğinde karanlığın enseme saplandığını hissettim. Eğer şimdi, böyle kalabalık bir yerde elektrik kesilse başımıza ne gelirdi?
İçerideki askerlerden biri bakışlarımı yakalayınca yeniden saate odaklanmış gibi yaptım. Sadece birkaç dakika geçmişti.
“Tarlalarım gitti. Böyle boyum kadar ayçiçeği doluydu. Ah, hepsi ölüp gidiyor. Afitap’ın çiçekleri de gi-”
“Dayı, Allah’ını seversen sus. Hepimizi yakacaksın şimdi.”
Karanlıkta durduğunda, görünmez olmayı istemeye başlıyordun. Kimse seni görmemeli, nefesini bile duymamalıydı. Kimsenin de ayağının altında dolaşmamalıydın; gelip kazayla sana çarpmamalılar, takılıp sendelememeliydiler. Yoksa aslında hedefi sen olmadığın bir öfke gürlemeye başlar, yaşadığın ilk şoku ve acıyı silerek üstünden geçerdi.
İlk konuşan, yaşlıca bir adam, kafasında kasketi, nasırlı ellerine hohluyordu. Gözleri ve burnu kızarmıştı. Güneşin kaybolması onun için kendi başına bir felaket değildi. Hayatına olan pratik yansımalarından korkuyordu olsa olsa. Bir anının kaybolması, bu yüzden çoktan kaybettiği birinin biraz daha eksilmesi. Hayatta kalmasını gerektiren sebepler azalırken, hayatta kalmasını sağlayacak kaynaklarını da kaybediyordu.
Onu susturan delikanlıysa atkısını bütün kafasına sarmış, sakalı ve yüzünün derinliklerine kaçmış gözleri dışında bedeninin bütün parçalarını gizlemeye çalışıyordu. İşte o, güneşin kaybolmasının tam olarak ne anlama geldiğini anlamamış olsa bile, dehşetini olduğu gibi hissedebilenlerdendi.
Güneşin onlardan alındıktan sonra kime verileceğini sormuyorlardı. En başta onlara verildiğinde de hiçbir soru sormamışlardı zaten.
İki saat ne zaman geçer?
Midemin üstünde, sağ tarafıma doğru keskin bir acı hissettim. Karaciğerim. Gözlerimi yumdum. Yanımda biri metal bir nesneyi yere bıraktı. Bir kafesti. İçerisindeki kartalın ıslak kokusu burnuma ulaşmadan önce bile biliyordum bunu.
“Yeniden mi?” diye sordu bana kartal. Kanatları kanlı. Zamanın her bir parçası tüylerinin üstüne çöreklenmişti. Gagası bir şey, tahminen et parçası geveliyor gibi hareket ediyordu. Eski anılar kolay unutulmazmış. Şu anda kafesinin kalın parmaklıklarının ardında olsa da bunun bir aldatmaca olduğunu bir tek ben biliyordum. Her an kanatlarını iki yana uzatıverebilir, hava bu hareketiyle dalgalanarak kafesi esneterek hepimizi içine alacak kadar genişleyebilir, parmaklıklar önce ayaklarımızın altına serilir gibi gözükebilir ama aslında hepimizin üstünde yükselerek tepemize çökebilirdi.
Aşağıya baktım. Tahtalarla zapt edilmiş, hiçbir yere gidemeyen ama her yere uzanan tren rayları. Atlayıp koşsam… Çantam çok ağırdı. Daha birkaç adım atamadan, kartal, suratını bedenime gömerdi.
“Bu sefer farklı,” diye yanıtladım onu. “Yeniden diyemezsin. Tekrarladığım bir şey değil bu. Hatta bir hata yapıyormuşum gibi tonlayamazsın da. Bu sefer, insanların hak etmediğini biliyorum.”
“O zaman daha vahim. Süzme salaksın demektir.”
“İnsanların hak etmemesi, insanlığın hak etmediği anlamına gelmez ki.”
Az önce göz göze geldiğim genççe ama çökük asker hâlâ bana bakıyordu. Bir kartalla konuştuğumu anlamamıştı şüphesiz. Yanımdakilerden biriyle konuştuğumu sanmış olmalıydı. Ama konuştuğum kişiye bakmıyordum ona göre. Çekingence kafamı eğmiştim. Bir kez daha göz göze geldiğimizde içerideki diğer iki askere bir şeyler söyledi, onlar dönüp beni süzerken dışarı çıktı.
Yanımızdaki, az önce konuşan iki adam da şaşkınlıkla bir bana bir kartala bakıyordu.
“Yalnız bu sefer kalbin de kırılacak, Prometheus,” dedi kartal, bana. “Belki son olur. Biliyorsun, bir sürü soruna neden oluyor bu yaptıkların.”
Beni koruyordu sözde. En çok kanıma dokunan buydu. Kasıklarımın üstüne oturmuş, kanlı suratının ardında gözleri parlarken attığı çığlık kulaklarımda titremeye devam ediyordu. Bu tabloda kimsenin kimseyi düşündüğü yoktu. Kartalın, yanımızdaki adamların, artık arkama kadar gelmiş olması gereken askerin, tren raylarının, geçmeyen saatlerin…
Arkamı döndüğümde, asker sahiden oradaydı. Zaten öyle olması gerekiyordu; görmüştüm bunu, biliyordum. Kehanetler… Bir şeyler söylüyordu ama ağzı oynarken sesi çıkmıyordu. Yavaşlamış, kendisini saatin akışına uydurmuştu. Havada donan tükürüğünden anlaşılıyordu, sinirliydi. Korktuğu için olduğunu biliyordum. Her seferinde korkmuşlardı. Beni unutmuş olmaları işlerini kolaylaştırmıyordu. Sadece yeni bir isim vermelerine neden oluyordu. Bu seferkiyle beni lanetleyecekleri kesinleşmişti.
Olması gerekenle olanların farklı olması ne kadar acınasıydı. Olması gerekenlerin doğasının kötücül olmasıysa bir yerde buna dayanıyordu.
“Salaksın,” dedi kartal bana. Zamanı aşan bir çığlık. Hepimizin önüne geçmişti ama kimseyi durduramıyordu.
Sonsuzluğa kaç tane iki saat sıkıştırabilirsiniz?
Ben bir tane bile sıkıştıramadım.
Çantama uzanıyordum. Asker de sırtındaki tüfeğini indiriyordu. Benim acelem yoktu, onunsa eli ayağı birbirine dolaşıyordu. Oysaki her şey tam olması gerektiği anda olacaktı. Kehanet başkasının parmaklarının ucundaydı.
Güneş, bir tüfeğin patlamasıyla yeryüzüne doğdu.
Rayların üzerine serilmiş göğsümün ortasından, bir çantanın içinden.

2025-02-02 03:16:40Why Privacy Matters and How to Protect It
Privacy is about control. It’s not about hiding yourself but deciding what others can see about you. Just as you don’t share everything when buying a magazine, technology shouldn’t force you to reveal more than needed.
Why Privacy is Important
-
Personal Control: Privacy lets you choose what parts of your life are visible. You shouldn’t have to share everything just to use a service.
-
Security Against Exploitation: Without privacy, people and groups can be targeted by companies or governments. This abuse can lead to data breaches or unnecessary surveillance.
-
Building Trust: Privacy is key to trust in relationships and communities. When your info is safe, you can transact and communicate without fear of misuse.
How to Protect Your Privacy 1. Think Before You Share: Only share what’s necessary and know why you’re doing it. 2. Use Encryption: Encrypt sensitive communications like emails or messages. 3. Control Data Sharing: Avoid oversharing personal details online. 4. Enable Privacy Tools: Use VPNs or privacy settings on social media to shield your data. 5. Be Mindful of Metadata: Understand that metadata (like location data) can reveal more about you than the content itself. 6. Support Privacy-Focused Brands: Choose services that prioritize privacy, like encrypted messaging apps. 7. Read Privacy Policies: Know what data you’re sharing and with whom. 8. Tools like privacy.io can help visualize your digital footprint. 9. Block Trackers: Use tools like DoNotTrackMe or uBlock Origin to stop trackers from collecting your data.
Conclusion
Protecting privacy is a vital step in safeguarding your personal freedoms. By taking proactive measures, you can control what information is accessible and ensure that your rights are respected. Remember, you are your own best advocate for privacy—trust no one but yourself to protect your data and identity.
Join the movement to champion privacy as a fundamental human right. Advocate for stronger laws and encourage others to take action, so we can all enjoy safer, more secure digital environments.

2024-01-14 13:55:28O Planetinha
Fumaça verde me entrando pelas narinas e um coro desafinado fazia uma base melódica.
nos confins da galáxia havia um planetinha isolado. Era um planeta feliz.
O homem vestido de mago começava a aparecer por detrás da fumaça verde.
O planetinha recebeu três presentes, mas o seu habitante, o homem, estava num estado de confusão tão grande que ameaçava estragá-los. Os homens já havia escravizado o primeiro presente, a vida; lutavam contra o segundo presente, a morte; e havia alguns que achavam que deviam destruir totalmente o terceiro, o amor, e com isto levar a desordem total ao pobre planetinha perdido, que se chamava Terra.
O coro desafinado entrou antes do "Terra" cantando várias vezes, como se imitasse um eco, "terra-terra-terraaa". Depois de uma pausa dramática, o homem vestido de mago voltou a falar.
Terra, nossa nave mãe.
Neste momento eu me afastei. À frente do palco onde o mago e seu coral faziam apelos à multidão havia vários estandes cobertos com a tradicional armação de quatro pernas e lona branca. Em todos os cantos da praça havia gente, gente dos mais variados tipos. Visitantes curiosos que se aproximavam atraídos pela fumaça verde e as barraquinhas, gente que aproveitava o movimento para vender doces sem pagar imposto, casais que se abraçavam de pé para espantar o frio, os tradicionais corredores que faziam seu cooper, gente cheia de barba e vestida para imitar os hippies dos anos 60 e vender colares estendidos no chão, transeuntes novos e velhos, vestidos como baladeiros ou como ativistas do ônibus grátis, grupos de ciclistas entusiastas.
O mago fazia agora apelos para que nós, os homens, habitantes do isolado planetinha, passássemos a ver o planetinha, nossa nave mãe, como um todo, e adquiríssemos a consciência de que ele estava entrando em maus lençóis. A idéia, reforçada pela logomarca do evento, era que parássemos de olhar só para a nossa vida e pensássemos no planeta.
A logomarca do evento, um desenho estilizado do planeta Terra, nada tinha a ver com seu nome: "Festival Andando de Bem com a Vida", mas havia sido ali colocada estrategicamente pelos organizadores, de quem parecia justamente sair a mensagem dita pelo mago.
Aquela multidão de pessoas que, assim como eu, tinham suas próprias preocupações, não podiam ver o quadro caótico que formavam, cada uma com seus atos isolados, ali naquela praça isolada, naquele planeta isolado. Quando o hippie barbudo, quase um Osho, assustava um casal para tentar vender-lhes um colar, a quantidade de caos que isto acrescentava à cena era gigantesca. Por um segundo, pude ver, como se estivesse de longe e acima, com toda a pretensão que este estado imaginativo carrega, a cena completa do caos.
Uma nave-mãe, dessas de ficção científica, habitada por milhões de pessoas, seguia no espaço sem rumo, e sem saber que logo à frente um longo precipício espacial a esperava, para a desgraça completa sua e de seus habitantes.
Acostumados àquela nave tanto quanto outrora estiveram acostumados à sua terra natal, os homens viviam as próprias vidas sem nem se lembrar que estavam vagando pelo espaço. Ninguém sabia quem estava conduzindo a nave, e ninguém se importava.
No final do filme descobre-se que era a soma completa do caos que cada habitante produzia, com seus gestos egoístas e incapazes de levar em conta a totalidade, é que determinava a direção da nave-mãe. O efeito, no entanto, não era imediato, como nunca é. Havia gente de verdade encarregada de conduzir a nave, mas era uma gente bêbada, mau-caráter, que vivia brigando pelo controle da nave e o poder que isto lhes dava. Poder, status, dinheiro!
Essa gente bêbada era atraída até ali pela corrupção das instituições e da moral comum que, no fundo no fundo, era causada pelo egoísmo da população, através de um complexo -- mas que no filme aparece simplificado pela ação individual de um magnata do divertimento público -- processo social.
O homem vestido de mago era mais um agente causador de caos, com sua cena cheia de fumaça e sua roupa estroboscópica, ele achava que estava fazendo o bem ao alertar sua platéia, todos as sextas-feiras, de que havia algo que precisava ser feito, que cada um que estava ali ouvindo era responsável pelo planeta. A sua incapacidade, porém, de explicar o que precisava ser feito só aumentava a angústia geral; a culpa que ele jogava sobre seu público, e que era prontamente aceita e passada em frente, aos familiares e amigos de cada um, atormentava-os diariamente e os impedia de ter uma vida decente no trabalho e em casa. As famílias, estressadas, estavam constantemente brigando e os motivos mais insignificantes eram responsáveis pelas mais horrendas conseqüências.
O mago, que após o show tirava o chapéu entortado e ia tomar cerveja num boteco, era responsável por uma parcela considerável do caos que levava a nave na direção do seu desgraçado fim. No filme, porém, um dos transeuntes que de passagem ouviu um pedaço do discurso do mago despertou em si mesmo uma consiência transformadora e, com poderes sobre-humanos que lhe foram então concedidos por uma ordem iniciática do bem ou não, usando só os seus poderes humanos mesmo, o transeunte -- na primeira versão do filme um homem, na segunda uma mulher -- consegue consertar as instituições e retirar os bêbados da condução da máquina. A questão da moral pública é ignorada para abreviar a trama, já com duas horas e quarenta de duração, mas subentende-se que ela também fora resolvida.
No planeta Terra real, que não está indo em direção alguma, preso pela gravidade ao Sol, e onde as pessoas vivem a própria vida porque lhes é impossível viver a dos outros, não têm uma consciência global de nada porque só é possível mesmo ter a consciência delas mesmas, e onde a maioria, de uma maneira ou de outra, está tentando como pode, fazer as coisas direito, o filme é exibido.
Para a maioria dos espectadores, é um filme que evoca reflexões, um filme forte. Por um segundo elas têm o mesmo vislumbre do caos generalizado que eu tive ali naquela praça. Para uma pequena parcela dos espectadores -- entre eles alguns dos que estavam na platéia do mago, o próprio mago, o seguidor do Osho, o casal de duas mulheres e o vendedor de brigadeiros, mas aos quais se somam também críticos de televisão e jornal e gente que fala pelos cotovelos na internet -- o filme é um horror, o filme é uma vulgarização de um problema real e sério, o filme apela para a figura do herói salvador e passa uma mensagem totalmente errada, de que a maioria da população pode continuar vivendo as suas própria vidinhas miseráveis enquanto espera por um herói que vem do Olimpo e os salva da mixórdia que eles mesmos causaram, é um filme que presta um enorme desserviço à causa.
No dia seguinte ao lançamento, num bar meio caro ali perto da praça, numa mesa com oito pessoas, entre elas seis do primeiro grupo e oito do segundo, discute-se se o filme levará ou não o Oscar. Eu estou em casa dormindo e não escuto nada.

2025-02-04 18:40:56What is it?
I stumbled upon the Elgato Stream Deck while aimlessly browsing the web, and I was instantly intrigued. But one question kept nagging me—how would I use this, and why do I even need it?
I don’t stream.
At first glance, it seemed like just another gadget to clutter my already cramped desk in my tiny Shanghai apartment. But curiosity got the best of me. After some research, I decided to give it a shot and see what all the hype was about.
And wow—was that hype justified.
This isn’t a deep-dive review covering every feature (there are plenty of those online). Instead, I want to share some of the workflows I’ve set up and hopefully get you thinking about the endless possibilities you could create with a Stream Deck.
If you’re someone who loves making computer tasks easier but struggles to remember keyboard shortcuts beyond Ctrl + V, this little device might just change the way you work.
Launching Apps and Websites
I won’t lie—my favorite use for the Stream Deck is the sheer convenience of pressing a button and instantly launching what I need.
Want to watch YouTube? Button.
Open Photoshop? Button.
Play a game? Button.
Check Bitcoin prices? Those are always on the display.
Sure, it’s a small thing, but the speed and ease of launching apps or navigating to websites make a surprising difference. What used to be a few clicks and keystrokes is now a single tap.
After using the Stream Deck for a while, my laptop feels... clunky. I’ve genuinely noticed an increase in my productivity and focus.
Custom Application Profiles
One of the most powerful features of the Stream Deck is its ability to switch profiles based on the application you’re using.
This means that every time you switch programs, the buttons automatically adjust to show relevant shortcuts and commands. It’s a game-changer for software with hundreds of keyboard shortcuts, making multitasking seamless.
I’ll admit—setting up custom profiles can be a bit time-consuming. The good news? You don’t have to start from scratch. There are tons of downloadable third-party profiles for popular programs like Illustrator, Photoshop, Final Cut Pro, DaVinci Resolve, Microsoft Office, and Ableton.
If your favorite app doesn’t have a pre-made profile, you can always build your own. It takes some effort, but once it's set up, the workflow improvements are worth it.
Music and Audio Control
I use an audio interface for lossless wired playback and external microphone support. The Stream Deck makes switching between my computer’s default mic and my studio mic effortless—no more digging through system preferences.
Even if you don’t use external audio gear, the Stream Deck still has plenty of value for music lovers.
It integrates with Apple Music and Spotify, letting you control playback, skip tracks, like songs, and add them to playlists—all without switching apps. Elgato is constantly adding new third-party integrations, which gives the device even more longevity.
Lighting and Smart Home Control
If you have smart home devices, the Stream Deck can act as a command center. It integrates with platforms like Philips Hue, LIFX, Nanoleaf, and IFTTT, letting you control lights, scenes, and colors with a single tap.
Want to set the mood for gaming, reading, or watching a movie? Done.
You can even use it to trigger other smart devices, like cameras, thermostats, or speakers, using IFTTT applets. The possibilities here are endless.
Finder and Document Shortcuts
One of the most unexpectedly useful features for me has been quick access to folders and files.
I’ve set up buttons for my most frequently used folders—Downloads, Desktop, and Documents—so I can access them instantly. I’ve also created buttons for specific files like spreadsheets and PDFs, so I don’t have to dig through folders to find them.
It sounds simple, but when juggling multiple projects, these little time-savers add up fast.
Final Thoughts
The Elgato Stream Deck is a surprisingly versatile tool that enhances productivity, creativity, and entertainment. Whether you’re launching apps, controlling music, managing smart devices, or creating complex workflows, it streamlines everyday tasks in a way that’s hard to go back from.
At first, I thought it was just for streamers. Now? I can’t imagine working without it.

2025-02-03 14:51:45Protecting Email Communications: A Guide for Privacy Activists
Safeguarding your communications is paramount, especially for activists who often face unique challenges. Encryption tools offer a vital layer of security, ensuring that your emails remain confidential and inaccessible to unauthorized parties. This guide will walk you through the process of using encryption tools effectively, providing both practical advice and essential insights.
Why Encryption Matters
Encryption transforms your communications into a secure format, making it difficult for unauthorized individuals to access or read your messages. Without encryption, even encrypted email services can expose metadata, which includes details like who sent the email, when it was sent, and the recipient's email address. Metadata can reveal sensitive information about your activities and location.
Key Encryption Tools
There are several tools available for encrypting emails, catering to different skill levels and preferences:
- PGP (Pretty Good Privacy)
-
For Tech-Savvy Users: PGP is a robust encryption tool that uses public and private keys. The recipient needs your public key to decrypt your messages. You can obtain your public key through a key server or directly from the recipient.
-
GPG (GNU Privacy Guard)
-
Free and Open Source: GPG is a user-friendly alternative to PGP, offering similar functionality. It's ideal for those who prefer an open-source solution.
-
ProtonMail
-
End-to-End Encryption: ProtonMail is popular among privacy-conscious individuals, offering end-to-end encryption and zero-knowledge encryption, meaning only the sender and recipient can access the message content.
-
Tresorit
-
Secure Communication: Tresorit provides end-to-end encrypted messaging with a focus on security and privacy, making it a favorite among activists and journalists.
-
Claws Mail
- User-Friendly Email Client: Claws Mail supports PGP encryption directly, making it an excellent choice for those who prefer a dedicated email client with built-in encryption features.
Steps to Encrypt Your Emails
- Choose a Tool:
-
Select the tool that best fits your needs and comfort level. Tools like PGP or GPG are suitable for those with some technical knowledge, while ProtonMail offers an easy-to-use interface.
-
Generate Keys:
-
Create a public key using your chosen tool. This key will be shared with recipients to enable them to encrypt their responses.
-
Share Your Public Key:
-
Ensure that the recipient has access to your public key through secure means, such as pasting it directly into an email or sharing it via a secure messaging platform.
-
Encrypt and Send:
- When composing an email, use your encryption tool to encrypt the message before sending. This ensures that only the recipient with your public key can decrypt the content.
Minimizing Metadata
Beyond encryption, consider these steps to reduce metadata exposure:
- Use Tor for Sending Emails:
-
Routing emails through Tor hides your IP address and makes communication more anonymous.
-
Avoid Revealing Identifiers:
-
Use .onion addresses when possible to avoid leaving a traceable email account.
-
Choose Privacy-Friendly Providers:
- Select email providers that do not require phone numbers or other personally identifiable information (PII) for registration.
Best Practices
- Avoid Using Real Email Accounts:
-
Create dedicated, disposable email accounts for encryption purposes to minimize your personal exposure.
-
Understand Legal Implications:
-
Be aware of laws in your country regarding encryption and digital privacy. Engaging in encrypted communications may have legal consequences, so understand when and how to use encryption responsibly.
-
Use Encrypted Backup Methods:
- Encrypt sensitive information stored on devices or cloud services to ensure it remains inaccessible if your device is compromised.
When Encryption Isn't Enough
While encryption protects content, there are limitations. Governments can legally compel decryption in certain circumstances, especially when they possess a warrant. Understanding these limits and considering the consequences of encryption is crucial for privacy activists.
Conclusion
Encryption is a vital tool for safeguarding communications, but it must be used wisely. By selecting the right tools, minimizing metadata, and understanding legal boundaries, privacy activists can effectively protect their emails while maintaining their commitment to privacy and freedom. Stay informed, stay secure, and always prioritize your digital well-being.

2025-02-01 14:46:05For the past few years, I've used February to get back on track with my fasting habits.
As I've described elsewhere, I try to do daily intermittent dry fasting. That's basically just a fancy way of saying that I stop eating and drinking fairly early and don't start again until later in the next today.
I'll try to do daily updates, throughout the month, for my own accountability.
Feel free to hop on if there's anything you need an accountability boost on.
I'm about to drink some coffee. It's been about 13 hours since I ate or drank anything. From my understanding, that's pretty much the minimum needed for any benefit.

@ f977c464:32fcbe00
2024-01-11 18:47:47Kendisini aynada ilk defa gördüğü o gün, diğerleri gibi olduğunu anlamıştı. Oysaki her insan biricik olmalıydı. Sözgelimi sinirlendiğinde bir kaşı diğerinden birkaç milimetre daha az çatılabilirdi veya sevindiğinde dudağı ona has bir açıyla dalgalanabilirdi. Hatta bunların hiçbiri mümkün değilse, en azından, gözlerinin içinde sadece onun sahip olabileceği bir ışık parlayabilirdi. Çok sıradan, öyle sıradan ki kimsenin fark etmediği o milyonlarca minik şeyden herhangi biri. Ne olursa.
Ama yansımasına bakarken bunların hiçbirini bulamadı ve diğer günlerden hiç de farklı başlamamış o gün, işe gitmek için vagonunun gelmesini beklediği alelade bir metro istasyonunda, içinde kaybolduğu illüzyon dağılmaya başladı.
İlk önce derisi döküldü. Tam olarak dökülmedi aslında, daha çok kıvılcımlara dönüşüp bedeninden fırlamış ve bir an sonra sönerek külleşmiş, havada dağılmıştı. Ardında da, kaybolmadan hemen önce, kısa süre için hayal meyal görülebilen, bir ruhun yok oluşuna ağıt yakan rengârenk peri cesetleri bırakmıştı. Beklenenin aksine, havaya toz kokusu yayıldı.
Dehşete düştü elbette. Dehşete düştüler. Panikle üstlerini yırtan 50 işçi. Her şeyin sebebiyse o vagon.
Saçları da döküldü. Her tel, yere varmadan önce, her santimde ikiye ayrıla ayrıla yok oldu.
Bütün yüzeylerin mat olduğu, hiçbir şeyin yansımadığı, suyun siyah aktığı ve kendine ancak kameralarla bakabildiğin bir dünyada, vagonun içine yerleştirilmiş bir aynadan ilk defa kendini görmek.
Gözlerinin akları buharlaşıp havada dağıldı, mercekleri boşalan yeri doldurmak için eriyip yayıldı. Gerçeği görmemek için yaratılmış, bu yüzden görmeye hazır olmayan ve hiç olmayacak gözler.
Her şeyin o anda sona erdiğini sanabilirdi insan. Derin bir karanlık ve ölüm. Görmenin görmek olduğu o anın bitişi.
Ben geldiğimde ölmüşlerdi.
Yani bozulmuşlardı demek istiyorum.
Belleklerini yeni taşıyıcılara takmam mümkün olmadı. Fiziksel olarak kusursuz durumdaydılar, olmayanları da tamir edebilirdim ama tüm o hengamede kendilerini baştan programlamış ve girdilerini modifiye etmişlerdi.
Belleklerden birini masanın üzerinden ileriye savurdu. Hınca hınç dolu bir barda oturuyorlardı. O ve arkadaşı.
Sırf şu kendisini insan sanan androidler travma geçirip delirmesin diye neler yapıyoruz, insanın aklı almıyor.
Eliyle arkasını işaret etti.
Polislerin söylediğine göre biri vagonun içerisine ayna yerleştirmiş. Bu zavallılar da kapı açılıp bir anda yansımalarını görünce kafayı kırmışlar.
Arkadaşı bunların ona ne hissettirdiğini sordu. Yani o kadar bozuk, insan olduğunu sanan androidi kendilerini parçalamış olarak yerde görmek onu sarsmamış mıydı?
Hayır, sonuçta belirli bir amaç için yaratılmış şeyler onlar. Kaliteli bir bilgisayarım bozulduğunda üzülürüm çünkü parasını ben vermişimdir. Bunlarsa devletin. Bana ne ki?
Arkadaşı anlayışla kafasını sallayıp suyundan bir yudum aldı. Kravatını biraz gevşetti.
Bira istemediğinden emin misin?
İstemediğini söyledi. Sahi, neden deliriyordu bu androidler?
Basit. Onların yapay zekâlarını kodlarken bir şeyler yazıyorlar. Yazılımcılar. Biliyorsun, ben donanımdayım. Bunlar da kendilerini insan sanıyorlar. Tiplerine bak.
Sesini alçalttı.
Arabalarda kaza testi yapılan mankenlere benziyor hepsi. Ağızları burunları bile yok ama şu geldiğimizden beri sakalını düzeltip duruyor mesela. Hayır, hepsi de diğerleri onun sakalı varmış sanıyor, o manyak bir şey.
Arkadaşı bunun delirmeleriyle bağlantısını çözemediğini söyledi. O da normal sesiyle konuşmaya devam etti.
Anlasana, aynayı falan ayırt edemiyor mercekleri. Lönk diye kendilerini görüyorlar. Böyle, olduğu gibi...
Nedenmiş peki? Ne gerek varmış?
Ne bileyim be abicim! Ahiret soruları gibi.
Birasına bakarak dalıp gitti. Sonra masaya abanarak arkadaşına iyice yaklaştı. Bulanık, bir tünelin ucundaki biri gibi, şekli şemalı belirsiz bir adam.
Ben seni nereden tanıyorum ki ulan? Kimsin sen?
Belleği makineden çıkardılar. İki kişiydiler. Soruşturmadan sorumlu memurlar.
─ Baştan mı başlıyoruz, diye sordu belleği elinde tutan ilk memur.
─ Bir kere daha deneyelim ama bu sefer direkt aynayı sorarak başla, diye cevapladı ikinci memur.
─ Bence de. Yeterince düzgün çalışıyor.
Simülasyon yüklenirken, ayakta, biraz arkada duran ve alnını kaşıyan ikinci memur sormaktan kendisini alamadı:
─ Bu androidleri niye böyle bir olay yerine göndermişler ki? Belli tost olacakları. İsraf. Gidip biz baksak aynayı kırıp delilleri mahvetmek zorunda da kalmazlar.
Diğer memur sandalyesinde hafifçe dönecek oldu, o sırada soruyu bilgisayarın hoparlöründen teknisyen cevapladı.
Hangi işimizde bir yamukluk yok ki be abi.
Ama bir son değildi. Üstlerindeki tüm illüzyon dağıldığında ve çıplak, cinsiyetsiz, birbirinin aynı bedenleriyle kaldıklarında sıra dünyaya gelmişti.
Yere düştüler. Elleri -bütün bedeni gibi siyah turmalinden, boğumları çelikten- yere değdiği anda, metronun zemini dağıldı.
Yerdeki karolar öncesinde beyazdı ve çok parlaktı. Tepelerindeki floresan, ışığını olduğu gibi yansıtıyor, tek bir lekenin olmadığı ve tek bir tozun uçmadığı istasyonu aydınlatıyorlardı.
Duvarlara duyurular asılmıştı. Örneğin, yarın akşam kültür merkezinde 20.00’da başlayacak bir tekno blues festivalinin cıvıl cıvıl afişi vardı. Onun yanında daha geniş, sarı puntolu harflerle yazılmış, yatay siyah kesiklerle çerçevesi çizilmiş, bir platformdan düşen çöp adamın bulunduğu “Dikkat! Sarı bandı geçmeyin!” uyarısı. Biraz ilerisinde günlük resmi gazete, onun ilerisinde bir aksiyon filminin ve başka bir romantik komedi filminin afişleri, yapılacakların ve yapılmayacakların söylendiği küçük puntolu çeşitli duyurular... Duvar uzayıp giden bir panoydu. On, on beş metrede bir tekrarlanıyordu.
Tüm istasyonun eni yüz metre kadar. Genişliği on metre civarı.
Önlerinde, açık kapısından o mendebur aynanın gözüktüğü vagon duruyordu. Metro, istasyona sığmayacak kadar uzundu. Bir kılıcın keskinliğiyle uzanıyor ama yer yer vagonların ek yerleriyle bölünüyordu.
Hiçbir vagonda pencere olmadığı için metronun içi, içlerindekiler meçhuldü.
Sonrasında karolar zerrelerine ayrılarak yükseldi. Floresanın ışığında her yeri toza boğdular ve ortalığı gri bir sisin altına gömdüler. Çok kısa bir an. Afişleri dalgalandırmadılar. Dalgalandırmaya vakitleri olmadı. Yerlerinden söküp aldılar en fazla. Işık birkaç kere sönüp yanarak direndi. Son kez söndüğünde bir daha geri gelmedi.
Yine de etraf aydınlıktı. Kırmızı, her yere eşit dağılan soluk bir ışıkla.
Yer tamamen tele dönüşmüştü. Altında çapraz hatlarla desteklenmiş demir bir iskelet. Işık birkaç metreden daha fazla aşağıya uzanamıyordu. Sonsuzluğa giden bir uçurum.
Duvarın yerini aynı teller ve demir iskelet almıştı. Arkasında, birbirine vidalarla tutturulmuş demir plakalardan oluşan, üstünden geçen boruların ek yerlerinden bazen ince buharların çıktığı ve bir süre asılı kaldıktan sonra ağır, yağlı bir havayla sürüklendiği bir koridor.
Diğer tarafta paslanmış, pencerelerindeki camlar kırıldığı için demir plakalarla kapatılmış külüstür bir metro. Kapının karşısındaki aynadan her şey olduğu gibi yansıyordu.
Bir konteynırın içini andıran bir evde, gerçi gayet de birbirine eklenmiş konteynırlardan oluşan bir şehirde “andıran” demek doğru olmayacağı için düpedüz bir konteynırın içinde, masaya mum görüntüsü vermek için koyulmuş, yarı katı yağ atıklarından şekillendirilmiş kütleleri yakmayı deniyordu. Kafasında hayvan kıllarından yapılmış grili siyahlı bir peruk. Aynı kıllardan kendisine gür bir bıyık da yapmıştı.
Üstünde mavi çöp poşetlerinden yapılmış, kravatlı, şık bir takım.
Masanın ayakları yerine oradan buradan çıkmış parçalar konulmuştu: bir arabanın şaft mili, üst üste konulmuş ve üstünde yazı okunamayan tenekeler, boş kitaplar, boş gazete balyaları... Hiçbir şeye yazı yazılmıyordu, gerek yoktu da zaten çünkü merkez veri bankası onları fark ettirmeden, merceklerden giren veriyi sentezleyerek insanlar için dolduruyordu. Yani, androidler için. Farklı şekilde isimlendirmek bir fark yaratacaksa.
Onların mercekleri için değil. Bağlantıları çok önceden kopmuştu.
─ Hayatım, sofra hazır, diye bağırdı yatak odasındaki karısına.
Sofrada tabak yerine düz, bardak yerine bükülmüş, çatal ve bıçak yerine sivriltilmiş plakalar.
Karısı salonun kapısında durakladı ve ancak kulaklarına kadar uzanan, kocasınınkine benzeyen, cansız, ölü hayvanların kıllarından ibaret peruğunu eliyle düzeltti. Dudağını, daha doğrusu dudağının olması gereken yeri koyu kırmızı bir yağ tabakasıyla renklendirmeyi denemişti. Biraz da yanaklarına sürmüştü.
─ Nasıl olmuş, diye sordu.
Sesi tek düzeydi ama hafif bir neşe olduğunu hissettiğinize yemin edebilirdiniz.
Üzerinde, çöp poşetlerinin içini yazısız gazete kağıtlarıyla doldurarak yaptığı iki parça giysi.
─ Çok güzelsin, diyerek kravatını düzeltti kocası.
─ Sen de öylesin, sevgilim.
Yaklaşıp kocasını öptü. Kocası da onu. Sonra nazikçe elinden tutarak, sandalyesini geriye çekerek oturmasına yardım etti.
Sofrada yemek niyetine hiçbir şey yoktu. Gerek de yoktu zaten.
Konteynırın kapısı gürültüyle tekmelenip içeri iki memur girene kadar birbirlerine öyküler anlattılar. O gün neler yaptıklarını. İşten erken çıkıp yemyeşil çimenlerde gezdiklerini, uçurtma uçurduklarını, kadının nasıl o elbiseyi bulmak için saatlerce gezip yorulduğunu, kocasının kısa süreliğine işe dönüp nasıl başarılı bir hamleyle yaşanan krizi çözdüğünü ve kadının yanına döndükten sonra, alışveriş merkezinde oturdukları yeni dondurmacının dondurmalarının ne kadar lezzetli olduğunu, boğazlarının ağrımasından korktuklarını...
Akşam film izleyebilirlerdi, televizyonda -boş ve mat bir plaka- güzel bir film oynayacaktı.
İki memur. Çıplak bedenleriyle birbirinin aynı. Ellerindeki silahları onlara doğrultmuşlardı. Mum ışığında, tertemiz bir örtünün serili olduğu masada, bardaklarında şaraplarla oturan ve henüz sofranın ortasındaki hindiye dokunmamış çifti gördüklerinde bocaladılar.
Hiç de androidlere bilinçli olarak zarar verebilecek gibi gözükmüyorlardı.
─ Sessiz kalma hakkına sahipsiniz, diye bağırdı içeri giren ikinci memur. Söylediğiniz her şey...
Cümlesini bitiremedi. Yatak odasındaki, masanın üzerinden gördüğü o şey, onunla aynı hareketleri yapan android, yoksa, bir aynadaki yansıması mıydı?
Bütün illüzyon o anda dağılmaya başladı.

2025-01-31 21:22:59In the summer of 2023, the Human Rights Foundation (HRF) launched a Bitcoin Bounty program aimed at funding software developers to create new tools and features for Bitcoin tailored to the needs of dissidents and human rights advocates challenging authoritarianism worldwide. These bounties ranged from UX improvements to privacy upgrades and open-sourcing closed and permissioned systems.
There were 11 bounties in total, each with specific objectives. The deadline was Dec. 31, 2024.
We are excited to announce that every single bounty was claimed and that the resulting tools and upgrades are now empowering human rights activists daily across popular apps such as Blue Wallet, Zeus, Stack Wallet, Iris, Coracle, Keeper, Bull Bitcoin, Cake Wallet, and more.
This program highlights the impact of collaboration between human rights activists and software developers to create better tools for freedom. HRF is proud to have played a role in this effort and looks forward to continuing similar programs in the future. Special credit goes to the Oslo Freedom Forum, where much of the critical interaction between developers and activists occurred.
This wave of bounties was inspired by a successful pilot project in 2021, executed in partnership with Strike and Jack Mallers, which supported developers like Will Cassarin and Calle. Their innovations later gave rise to important advancements such as zaps in Nostr and the Cashu ecash protocol.
Bounty Details
1. Open-Sourcing the Design Guide
Winner: CypherStack for porting the Bitcoin UI Kit from Figma to an open-source Penpot project (2 BTC awarded).
Many UI kits are created using proprietary software like Figma. While these tools are powerful, they require licenses and are not accessible to everyone — an obstacle for developers working on open-source projects or those with limited funds. This creates a barrier to entry for designers and developers wanting to contribute to the Bitcoin ecosystem. This bounty was awarded to CypherStack for porting the Bitcoin UI Kit from Figma to Penpot, an open-source design tool similar to Figma, but free and accessible to everyone. This helped democratize access to information and resources, promote collaboration, and make it easier for developers to create high-quality Bitcoin tools, which in turn helped to increase Bitcoin adoption.
2. Serverless Payjoin
Winners: This is a two-part bounty. The first bounty is for the development of the Serverless Payjoin specification, and the second bounty is for any wallets that implement Serverless Payjoin.
Part 1: Dan Gould for his work on PayJoin V2 (1 BTC)
Part 2: Dan Gould, Spacebear from Payjoin DevKit, and Bull Bitcoin app, for their collaborative effort implementing Payjoin into the Bull Bitcoin wallet (0.5 BTC split three ways).
PayJoin is a privacy upgrade to Bitcoin that flusters mass surveillance attempts on the network. Traditional implementations have required the receiver to run a server for transaction coordination, creating a barrier to adoption. Serverless PayJoin removed this dependency and simplified the process. Serverless PayJoin also eliminated the need for receiver-hosted infrastructure and reduced censorship risks by removing a central point of failure — a significant advantage for activists and nonprofits operating under repressive regimes. This bounty resulted in the first mobile app (Bull Bitcoin) with integrated PayJoin send and receive support, an important advancement that provided robust privacy protections against surveillance for at-risk individuals.
3. End-to-End Encrypted Nostr Group Chats
Winners: Martti Malmi for incorporating encrypted group chat functionality into the Iris Nostr client (1 BTC) and to Vitor Pamplona, hodlbod, and Paul Miller for their work on NIP-17, which allowed users to encrypt and share Nostr messages in a way that can be recognized across different Nostr clients (1 BTC).
End-to-End Encrypted (E2EE) Nostr Group Chats are private, secure messaging groups built on the Nostr protocol, a decentralized communication system. While Nostr messages are already encrypted, they still expose metadata, allowing outside observers to see who is communicating and when. This bounty focused on preventing metadata leakage, ensuring that these details remain private. By leveraging Nostr’s decentralized architecture, these chats offered censorship resistance. They prevented conversations from being surveilled, blocked, or controlled by a central authority, and as a result of this bounty, have now been implemented into popular Nostr clients like Iris, Amethyst, and Coracle. This is an important step forward for activists, journalists, and communities who risk losing their freedom of speech under oppressive regimes.
4. Silent Payments
Winners: cygnet3 and Sosthene for their contributions to critical libraries for delivering Silent Payments and for developing a mobile wallet capable of sending and receiving Silent Payments without requiring a full node (1 BTC).
Silent Payments are a privacy-enhancing Bitcoin addressing scheme that allows a sender to generate a unique static address for a recipient without requiring any interaction (while still allowing the recipient to detect and spend the received funds). This breaks common tracking methods used by surveillance firms and autocracies and makes it harder to link payments to a specific recipient. By improving on the privacy of traditional Bitcoin addresses, Silent Payments enhanced financial privacy, making them ideal for donations, salaries, and other sensitive transactions. This bounty code has been fully integrated into Cake Wallet, and several other major wallets like Wasabi, Blue Wallet, and Bitbox have added partial functionality. This brings Silent Payments to tens of thousands of users and marks a major step in real-world Bitcoin privacy.
5. Human-Readable Offers
Winners: Stephen DeLorme, Chad Welch, and Evan Kaloudis for Twelve Cash and its integration into Zeus Wallet (1 BTC).
Human-Readable Offers simplify Bitcoin payments by replacing complex Bitcoin addresses and invoices with user-friendly text. This is especially important for Lightning Network transactions, which currently involve a cumbersome process of generating invoices for each payment. With Human-Readable Offers, sending Lightning payments becomes as simple as sending an email (just by entering a username). This approach, similar to many fintech apps today, reduces errors, lowers the barrier to entry, increases trust, and is crucial for broader adoption of Bitcoin among new and seasoned users alike. It’s also important for people who don’t have access to smartphones and cannot copy and paste or use QR codes. Today, as a result of this bounty, Zeus users connected to a Core Lightning node can create a human-readable Bolt 12 offer to privately receive donations.
6. Self-Custodial Mobile Lightning Address
Winner: Evan Kaloudis for Zeus Wallet (1 BTC).
Activists, nonprofits, and content creators often use Lightning addresses to receive donations quickly and easily. However, setting up and managing a Lightning address presents a challenge: users have to choose between the self-sovereignty of managing their own web server (a complex process) or the convenience of a custodial service, which requires trusting a third party with their funds. This bounty directly addressed this issue. It allowed users of Zeus Wallet, one of the most popular self-custodial Bitcoin Lightning wallets, to easily and securely receive donations through a Lightning address while maintaining control of their funds.
7. Mobile Border Wallets
Winner: Bitcoin Tribe for their border wallet functionality, allowing users to create and memorize seeds without relying on written backups, and for building a React Native library, making it easier for other wallets to integrate this feature (2 BTC).
Mobile Border Wallets aimed to solve a critical problem with traditional Bitcoin seed phrase backups: they’re often written down on paper, making them susceptible to being lost, destroyed, or stolen. This makes securing a user’s Bitcoin a delicate balance between security and accessibility. It also makes it challenging, especially for activists or refugees who frequently cross international borders. Border Wallets offered a solution to this problem. Instead of writing down a 12- or 24-word seed phrase and finding a secure place to store it, users can upload a randomly generated grid of words to the cloud and memorize a pattern to secure their seed phrase, similar to a pattern a user would memorize and draw on an Android device to unlock it. This initiative resulted in a user-friendly mobile app that allowed users to create Border Wallets digitally, enhancing accessibility and offering an alternative to physical storage like printed paper or metal seed plates.
8. Easy Mobile Multisig
Winner: Bitcoin Keeper (1 BTC).
Multi-signature wallets allow multiple users to collaboratively control a Bitcoin wallet. This enhances security by requiring consensus before funds can be moved. Traditional multisig wallets often require physical hardware wallets or involve subscription fees, presenting a significant barrier for organizations exploring Bitcoin adoption. This bounty funded the development of easy mobile multisig functionality in the Bitcoin Keeper app, enabling users to set up a 2-of-3 multisig (requiring two out of three keys to authorize spending) to secure and manage their bitcoin. This is a great feature for activists to prevent government seizure of funds: even if one key holder gets detained, the funds are safe so long as the other two key holders are safe. The idea is to make sure two of the keys are held by entities outside of one’s country or threat zone.
9. FROST Multisig Wallet
Winner: CypherStack for Stack Wallet, which enables dynamic multisig using FROST, allowing users to modify signer sets without moving funds (1 BTC).
Multisig (multisignature) wallets require multiple signatures to authorize a transaction. This enhances security by distributing control over funds. However, traditional multisig setups — while secure — can be inflexible. If you need to change the set of signers, it often requires moving all the funds to a new multisig wallet with the updated signer set. This is burdensome, time-consuming, and incurs fees. FROST is a cryptographic protocol that offers significant advantages for multisig wallets. It provides dynamic multisig functionality, meaning users can easily adjust their signer sets as needed without affecting the funds within. This is an important functionality for nonprofits and civil society groups who often need to adjust their authorized signatories, especially in situations where a regime may seize a private key and that key then needs to be deprecated. This dynamic kind of secure setup is now available for activists to use on the Stack Wallet.
10. Cashu Upgrades
Winners: eNuts Wallet (0.5 BTC), Misovan for Minibits Wallet (0.5 BTC), Gandlaf for Proxnut (0.5 BTC), and Gandlaf for adding Cashu-TS restore functionality (0.5 BTC).
Cashu is a digital cash system designed for privacy and speed. It is like physical cash, but in digital form and uses blind signatures for private transactions. With Cashu, transactions are instant, low-fee, and can operate offline. There is no blockchain or transaction graph to be surveilled. Bounty recipients addressed critical aspects of usability and accessibility for Cashu tools: eNuts and Minibits Wallets brought Cashu to iOS and Android users worldwide, Proxnut enabled easy web integration for payments, and Cashu-TS Restore added crucial seed phrase backup. Together, these projects have taken Cashu from a more theoretical concept to a practical one and have been relevant for use cases like donations, content monetization, daily transactions, and cross-border payments.
11. BIP47 Expansion
Winner: Blue Wallet (0.5 BTC) for adding BIP 47 support.
BIP47 is a Bitcoin Improvement Proposal that enhances payment privacy for Bitcoin users. In Bitcoin, it’s generally considered bad privacy practice to reuse the same Bitcoin address for multiple transactions. It can link those transactions together and make it easier to track a user’s spending in high-risk environments. Generating a new address for each payment has become a common workaround, but this becomes cumbersome. BIP47 solves this with reusable payment codes. Users receiving funds generate a BIP47 payment code and share it with those who will be sending them payments. Each time a payment is initiated, a new, unused Bitcoin address is generated from the recipient’s payment code. This ensures every transaction uses a unique address. Blue Wallet received this bounty for integrating BIP47 support, making this important privacy enhancement accessible to its growing user base.

2025-01-31 16:28:47Here are today's picks using my proprietary betting strategy at Freebitcoin. For details about what Risk Balanced Odds Arbitrage is and why it works see https://stacker.news/items/342765/r/Undisciplined.
For a hypothetical 1k-ish wager on each match, distribute your sats as follows:
| Outcome 1 | Outcome 2 | Outcome 3 | Bet 1 | Bet 2 | Bet 3 | |--------------|-------------|--------------|-------|-------|-------| | Napoli| Udinese| Draw | 688| 125| 222| | Inter Milan| Fiorentina| Draw | 667| 133| 217| | Empoli| AC Milan| Draw | 200| 571| 250| | Como| Juventus| Draw | 279| 464| 286| | Sevilla| Barcelona| Draw | 174| 630| 222| | Real Sociedad| Espanyol| Draw | 660| 133| 238| | Real Madrid| Atletico Madrid| Draw | 565| 211| 263| | RB Leipzig| FC St Pauli| Draw | 652| 154| 217| | FC Bayern| Werder| Draw | 875| 53| 100| | Dortmund| VfB Stuttgart| Draw | 458| 313| 263| | Man City| Newcastle| Draw | 588| 213| 222| | Leicester| Arsenal| Draw | 100| 750| 167| | Everton| Liverpool| Draw | 125| 688| 200| | Brighton| Chelsea| Draw | 323| 421| 267|
Overall, I'm holding steady at about a 2.5% return with this approach.
I still haven't precisely identified where the threshold is, but it might be worth skipping any of these with a "time weight multiplier" lower than 90.
A note of caution about Freebitcoin: they recorded the wrong outcome for last week's Bills vs Ravens game and as of yet have not corrected it. I recall one other instance of something similar happening, so proceed with caution.
This RBOA strategy is largely immune from that problem, but be aware of it when just betting on one outcome.

2025-02-02 13:39:49Why You Should Only Run DeepSeek Locally: A Privacy Perspective and how to
In an era where AI tools promise immense utility, the decision to run DeepSeek locally is not merely about functionality but also about safeguarding privacy and security. Here's the rationale why:
-
Control Over Data Access: Running DeepSeek locally ensures that data processing occurs on your own machine or server, allowing you to have full control over who can access the system. This reduces the risk of unauthorized access and misuse.
-
Data Privacy: By keeping computations local, you ensure that personal data does not leave your control, minimizing the risk of exposure through cloud-based services.
-
Security Measures: Local operation provides an additional layer of security. You can implement access controls, monitor usage, and respond to incidents more effectively, which might be harder or impossible when relying on third-party platforms.
-
Practical Implementation: Tools like Ollama and OpenWebUI facilitate setting up a local environment, making it accessible even for those with limited technical expertise. This setup empowers individuals to leverage AI capabilities while maintaining privacy.
-
Right to Control Data: Privacy is a fundamental right, and running DeepSeek locally respects this by allowing users to decide what data they share and how it's accessed. This empowers individuals to make informed choices about their personal data.
For those prioritizing privacy, this approach is not just beneficial—it's essential.
Running DeepSeek Locally: A Guide for Individual Home Users
DeepSeek is a powerful AI search engine that can help with various tasks, but running it locally gives you greater control over your data and privacy. Here’s how you can set it up at home.
What You’ll Need
- A Computer: A desktop or laptop with sufficient processing power (at least 4GB RAM).
- Python and pip: To install and run DeepSeek.
- Ollama: An open-source tool that allows you to run AI models locally.
- OpenWebUI: A simple web interface for interacting with Ollama.
Step-by-Step Guide
1. Install the Prerequisites
- Python: Download and install Python from https://www.python.org.
- pip: Use pip to install Python packages.
bash pip install --upgrade pip
- Ollama:
bash pip install ollama
- OpenWebUI: Visit https://github.com/DeepSeek-LLM/openwebui and follow the instructions to install it.
2. Set Up Ollama
- Clone the official Ollama repository:
bash git clone https://github.com/OllamaAI/Ollama.git cd Ollama
- Follow the installation guide on https://ollama.ai to set it up.
3. Run DeepSeek Locally
- Use OpenWebUI as your interface:
bash # Start OpenWebUI (open a terminal and run this): python openwebui.py --model deepseek-llm-v0.2-beta
- A web browser will open, allowing you to interact with DeepSeek.
Tips for Optimization
- Reduce Memory Usage: Use smaller models like
deepseek-llm-v0.2-beta
if your computer has limited resources. - Limit Model Access: Only allow authorized users to access the system by restricting IP addresses or using a VPN.
- Regular Updates: Keep all software up to date to protect against vulnerabilities.
Why Run DeepSeek Locally?
- Privacy: Your data stays on your local machine, reducing the risk of unauthorized access.
- Flexability: Running locally allows you to build specific models for specific uses and provide them with RAG data.
Advocating for privacy does not finance itself. If you enjoyed this article, please consider zapping or sending monero

@ bbb5dda0:f09e2747
2025-02-04 03:58:50This past week got me a lot of frustration with the GitHub actions runner and debugging it. Really testing my patience, but at least i saw a bit of progress. TollGate's had a nice wrap-up for the Proof Of Concept app, which some great new ideas on how to make the user experience even better! Let's dive in!
GitHub Actions
I've been having a low-key fight with the github actions runner containers. I have spent a lot of time trying to figure out WHY the blossom upload action would just not work. I was quick to find out that the action is being ran with an older version of NodeJS (v18) while the blossom uploader requires v20. Not a big deal you'd say as i just set the version to 20 in the pipeline. However, doing that explicitly had zero impact, and after diving down the github runner rabbit hole i concluded that the Actions that are imported (from marketplace) will just run with whatever node version is already installed in the runner's docker image. Which in the case of the act runner is Node 18. I tried updating to the latest images but I haven't been able to find a compatible one yet...
Payments
I've been working on getting the money aspect working in the ci-cd runner. I added a wallet and a scheduled payout. I took this from the nostr-epoxy project and did some updates to upgrade to cashu-ts v2.
I added some advertisement info like the specs of the machine that the runner is on. I've been pondering how the payment flow should work though. See the problem is that because of the nature of this DVM, it cannot predict how long a job will take to execute, a customer can literally do anything in their pipeline that will make a job last forever. I think for that reason there has to be some kind of deposit/credit or stream besides the one-off payment. I made a post asking what the best way would be: nostr:note17apw8unznvwx2k3z48t7qz6cq26tk077w83qh3f7zxukfrrfukhs7mpcsn
I currently feel best about the option of just sending a bunch of ecash that will sure be enough to execute the job (and otherwise act as the time-out) and that if the DVM uses less of that money, it will send it back as pubkey locked cashu tokens, to a given npub. Maybe NIP-60 can be a great way to handle returning the 'change' to the user.
Some ideas i have now: - Billing should be per second - Advertising should: - advertise as sats/minute - include specs of the machine, ideally searchable by tag
Job request
So the flow i'm thinking of is:
-
User posts request
- repository
- branch
- yaml path
- bid (max price per minute)
- min_vcpu
- min_ram
- min_storage
-
DVM responds with
- price per minute
- vcpu
- ram
- storage
- runner-types
- price per minute
-
User posts request:
- ... [same as above]
- cashu payment
- cashu return pubkey + relay
User Interface
I also worked on building out a very basic user interface to run the GitHub Actions dvm.
The UI then shows all feedback to the job, where the first feedback event you can see gives back a status processing, and the next one gives back the console output of the pipeline run.
nostr:npub15qydau2hjma6ngxkl2cyar74wzyjshvl65za5k5rl69264ar2exs5cyejr and I agreed he'll copy over this basic setup into his upcoming version of gitWorkshop.dev which I can then build upon so we can experiment with the User Experience (how to handle competing Runners, display results, payments, etc...)
Tollgate
There's also been the issue that has been bothering me since last week: Being able to dismiss a captive portal programatically in the Android app.
During a weekly check-in that nostr:npub1k03rader0vm94j5ee8fg7pc2x9xkr2phu77sljas7qu5mh8mvgvqpe8rty and I set up we discussed the issue. To me, it's a problem having the user to jump through all these hoops to connect, which should be as much automated as possible.
We discussed what if we'd ditch the open network and go with a WPA2 (password) protected one and have no captive portal. But then we lose the ability to do onboarding / expose users to Tollgate through the captive portal. Then the idea came up to create an extra (hidden) network for the app to use, while keeping the open one with the captive portal. I did not know it was possible to create multiple networks on the same (physical) radio, but apparently it's quite common. You lose a bit on efficiency but it shouldn't be too bad. The only challenge would be to exempt this network from getting a captive portal while still using the OpenNDS software to manage user's sessions. We'll see but this gives me a lot of hope for a seamless user experience!
After this call, despite our possible new direction I did want to try and get the full app flow working, to validate if it's possible at all. And after some digging int the Tauri docs and even their discord community i finally found what the issue was with me not receiving the android event for the captive portal. I'd ben adding the listener for this event to the

@ fa0165a0:03397073
2023-10-06 19:25:08I just tested building a browser plugin, it was easier than I thought. Here I'll walk you through the steps of creating a minimal working example of a browser plugin, a.k.a. the "Hello World" of browser plugins.
First of all there are two main browser platforms out there, Chromium and Mozilla. They do some things a little differently, but similar enough that we can build a plugin that works on both. This plugin will work in both, I'll describe the firefox version, but the chromium version is very similar.
What is a browser plugin?
Simply put, a browser plugin is a program that runs in the browser. It can do things like modify the content of a webpage, or add new functionality to the browser. It's a way to extend the browser with custom functionality. Common examples are ad blockers, password managers, and video downloaders.
In technical terms, they are plugins that can insert html-css-js into your browser experience.
How to build a browser plugin
Step 0: Basics
You'll need a computer, a text editor and a browser. For testing and development I personally think that the firefox developer edition is the easiest to work with. But any Chrome based browser will also do.
Create a working directory on your computer, name it anything you like. I'll call mine
hello-world-browser-plugin
. Open the directory and create a file calledmanifest.json
. This is the most important file of your plugin, and it must be named exactly right.Step 1: manifest.json
After creation open your file
manifest.json
in your text editor and paste the following code:json { "manifest_version": 3, "name": "Hello World", "version": "1.0", "description": "A simple 'Hello World' browser extension", "content_scripts": [ { "matches": ["<all_urls>"], "js": ["hello.js"] //The name of your script file. // "css": ["hello.css"] //The name of your css file. } ] }
If you wonder what the
json
file format is, it's a normal text file with a special syntax such that a computer can easily read it. It's thejson
syntax you see in the code above. Let's go through what's being said here. (If you are not interested, just skip to the next step after pasting this we are done here.)manifest_version
: This is the version of the manifest file format. It's currently at version 3, and it's the latest version. It's important that you set this to 3, otherwise your plugin won't work.name
: This is the name of your plugin. It can be anything you like.version
: This is the version of your plugin. It can be anything you like.description
: This is the description of your plugin. It can be anything you like.content_scripts
: This is where you define what your plugin does. It's a list of scripts that will be executed when the browser loads a webpage. In this case we have one script, calledhello.js
. It's the script that we'll create in the next step.matches
: This is a list of urls that the script will be executed on. In this case we have<all_urls>
, which means that the script will be executed on all urls. You can also specify a specific url, likehttps://brave.com/*
, which means that the script will only be executed on urls that start withhttps://brave.com/
.js
: This is a list of javascript files that will be executed. In this case we have one file, calledhello.js
. It's the script that we'll create in the next step.css
: This is where you can add a list of css files that will be executed. In this case we have none, but you can add css files here if you want to.//
: Text following these two characters are comments. They are ignored by the computer, You can add comments anywhere you like, and they are a good way to document your code.
Step 2: hello.js
Now it's time to create another file in your project folder. This time we'll call it
hello.js
. When created, open it in your text editor and paste the following code:js console.log("Hello World!");
That's javascript code, and it's what will be executed when you run your plugin. It's a simpleconsole.log
statement, which will print the text "Hello World!" to the console. The console is a place where the browser prints out messages, and it's a good place to start when debugging your plugin.Step 3: Load and launch your plugin
Firefox
Now it's time to load your plugin into your browser. Open your browser and go to the url
about:debugging#/runtime/this-firefox
. You should see a page that looks something like this:Click the button that says "Load Temporary Add-on...". A file dialog will open, navigate to your project folder and select the file
manifest.json
. Your plugin should now be loaded and running.Go to a website, any website, and open the inspector then navigate to the console. You'll find the inspector by right-clicking anywhere within the webpage, and click "Inspector" in the drop-down menu. When opening the console you might see some log messages from the site you visited and... you should see the text "Hello World!" printed there, from our little plugin! Congratulations!
Chrome
Open your browser and go to the url
chrome://extensions/
. Click the button that says "Load unpacked". A file dialog will open, navigate to your project folder and select the folderhello-world-browser-plugin
. Your plugin should now be loaded and running.Note the difference, of selecting the file
manifest.json
in firefox, and selecting the folderhello-world-browser-plugin
in chrome. Otherwise, the process is the same. So I'll repeat the same text as above: (for those who skipped ahead..)Go to a website, any website, and open the inspector then navigate to the console. You'll find the inspector by right-clicking anywhere within the webpage, and click "Inspector" in the drop-down menu. When opening the console you might see some log messages from the site you visited and... you should see the text "Hello World!" printed there, from our little plugin! Congratulations!
As you can see this isn't as complicated as one might think. Having preformed a "Hello-World!"-project is a very useful and valuable first step. These setup steps are the basics for any browser plugin, and you can build on this to create more advanced plugins.

2025-01-31 08:27:34Large Language Models (LLMs) have revolutionized how we interact with artificial intelligence, and one of their most powerful features is tool use - the ability to execute external functions to accomplish tasks. However, the current paradigm of LLM tool use remains largely constrained within closed ecosystems. Data Vending Machines (DVMs) offer an alternative to local, built-in tools through a decentralized marketplace. This decentralized approach enables independent developers to continuously create new tools, letting the entire system evolve based on actual needs.
Understanding LLM Tool Use
Tool use, also known as function calling, enables LLMs to interact with external systems and APIs. Instead of simply generating text, an LLM can choose to execute predefined functions when appropriate. For example, when asked about the weather, rather than making up a response, the model can call a weather API to get accurate, real-time data.
Traditionally, these tools are implemented as a fixed set of functions within the application's tech stack:
```python
Traditional function calling example (this exists within a closed tech stack)
def get_weather(location: str, date: str) -> dict: """Get weather information for a specific location and date.""" api_key = os.environ["WEATHER_API_KEY"] return weather_api.fetch(location, date, api_key)
LLM would call this function like:
result = get_weather("San Francisco", "2024-01-31") ```
Enter Data Vending Machines
DVMs represent a paradigm shift in how we think about LLM tool use. Instead of relying on locally defined functions, DVMs provide a decentralized marketplace of capabilities that any LLM can access. These "functions" exist as independent services on the Nostr network, available to anyone willing to pay for their use.
Here's how a DVM call might look compared to a traditional function call:
```json
partial data of an example call to a weather DVM
{ ... "kind": "5493", "pubkey": "
", "tags": [ ["payment", "100", "sats/ecash"] ], "content": { "service": "weather", "params": { "location": "San Francisco", "date": "2024-01-31" } } ... } ``` Note: This is a motivating example. Weather data DVMs don't exist yet. Most DVM requests don't include payment up front, but with ecash and zaps, it is possible to do. The format of the params may differ as well.
The Power of Market Dynamics
What makes DVMs particularly compelling for LLM tool use is their market-driven nature:
-
Competition Drives Innovation: Multiple DVMs can offer similar services, competing on price, quality, and speed. This natural competition leads to better services and lower prices.
-
Dynamic Expansion: Unlike traditional tool use where new capabilities must be explicitly added to the system, DVM-enabled LLMs can discover and utilize new tools as they become available in the marketplace.
-
Economic Incentives: DVM operators are incentivized to create and maintain high-quality services through direct monetary compensation.
Implementation Architecture
A basic implementation of a user facing DVM-based Tool Use LLM might include:
- Manager DVM: Acts as the central coordinator, maintaining:
- Conversation state and history
- System prompts and user preferences
- Wallet for handling payments to DVMs
-
Logic for DVM discovery and selection
-
User Interface: A chat interface that communicates with the manager DVM
-
LLM Service: Handles the core language model capabilities and decision-making about when to use DVMs
-
DVM Registry: Maintains a directory of available DVMs and their capabilities (like the data available on DVMDash; see nostr:naddr1qvzqqqr4gupzpkscaxrqqs8nhaynsahuz6c6jy4wtfhkl2x4zkwrmc4cyvaqmxz3qqxnzdejxv6nyd34xscnjd3sz05q9v)
Advanced Capabilities
The true power of DVM-based tool use emerges when we consider advanced scenarios:
- Self-Expanding Capabilities: When an LLM encounters a request it can't fulfill with existing DVMs, it could:
- Create bounties for new DVM development
- Fund the development of new capabilities
-
Coordinate with multiple DVMs to compose novel solutions
-
Economic Agency: By maintaining its own wallet, the system can:
- Generate revenue from user requests
- Pay for DVM services
- Fund its own expansion and improvement
Safety and Control
While the open nature of DVMs might raise concerns, several safety mechanisms can be implemented:
-
Human-in-the-Loop Confirmation: Users must approve DVM calls before execution, similar to how CLI tools ask for confirmation before significant actions.
-
Reputation Systems: DVMs can build reputation scores based on successful transactions and user feedback.
-
Cost Controls: Users can set spending limits and approve budgets for specific tasks.
Implications and Future Potential
The combination of Tool Use LLMs and DVMs creates a powerful new paradigm for AI capabilities:
-
Democratized Innovation: Anyone can create and monetize new AI capabilities by launching a DVM.
-
Organic Growth: The system can evolve based on real user needs and market demands.
-
Economic Sustainability: The payment mechanism ensures sustainable development and maintenance of AI tools.
Conclusion
By leveraging the Nostr protocol, DVMs enable Tool Use LLMs to access a distributed network of capabilities that would be impossible to build in a traditional, centralized way. For example, a single LLM can seamlessly use specialized tools from hundreds of independent developers - from a service that matches local freelancers to jobs to one that indexes local community events - without any prior coordination. This creates an AI ecosystem where capabilities emerge through market demand rather than central planning, with developers anywhere in the world able to add new tools that every LLM can discover and use.

2025-02-04 02:57:25The Damage Node is not just a verification engine—it is an autonomous executor of behaviors defined through the PoW blockchain. This allows for adaptive, accountable, and transparent execution of security and counter-surveillance mechanisms while remaining flexible enough to meet any operational need.
By integrating behavioral logic, cryptographic proofs, and decentralized execution, the Damage Node becomes a powerful shield and countermeasure system for individuals and groups operating under constant digital threat.
Core Concept: Damage Nodes as Autonomous Behavioral Executors
Damage Nodes listen to verifiable behaviors encoded on the PoW blockchain.
These behaviors define security policies, counter-surveillance actions, automated transactions, and decentralized decision-making processes.
Execution is enforced by the blockchain, ensuring absolute transparency and accountability—no action can occur without proof.
Nodes can dynamically extend their capabilities by adopting new behaviors via blockchain updates, ensuring they remain adaptable.
Example of Behavioral Execution
A Damage Node can be programmed to execute counter-surveillance actions if an individual's digital footprint is flagged by an AI-controlled system.
Trigger: An external surveillance system attempts to track a protected user.
Behavior Execution:
The node initiates a verified proof-of-presence falsification (broadcasting misleading metadata).
The node forces encrypted rerouting of communications over a private, non-ISP-controlled relay.
The node executes cryptographic evidence logging, proving that the tracking attempt occurred.
The node pays out a bounty (Lightning) for detected adversarial actions, incentivizing counter-intelligence.
How Damage Nodes Provide Shielding & Countermeasures
- Behavior-Driven Shielding for Individuals
Zero-Knowledge Identity Protection: Nodes execute self-sovereign identity verification that prevents AI from profiling users without explicit, cryptographically signed consent.
Automated Surveillance Disruption: If an AI attempts to track or flag an individual, the node executes behavioral obfuscation tactics such as:
Decoy digital presence broadcasting to mislead tracking algorithms.
Transaction splitting & anonymization to prevent financial surveillance.
Forced dissociation of metadata from physical locations.
- Group-Level Protection & Autonomous Coordination
Damage Nodes can be configured to execute behaviors for an entire decentralized network, such as:
Encrypted Group Communications: Nodes enforce trustless, encrypted messaging protocols that prevent AI-based censorship.
Automatic Secure Fund Distribution: If an entity is targeted, Damage Nodes can autonomously release emergency funds in BTC/Lightning to predesignated safe parties.
Counter-Surveillance Deployments: Nodes can activate sensor networks, scan for unauthorized tracking devices, and trigger security protocols.
- Built-In Accountability & Transparency as a Defensive Measure
Every execution is verified by the blockchain → no action is hidden or arbitrary.
Rules for behavior execution are immutable → even node operators cannot alter them without proof-of-consensus.
AI and governments cannot fabricate unverifiable evidence → if it didn't happen on-chain, it didn't happen.
Users can audit every action taken by the Damage Node to ensure no corruption or misuse.
- Extensible Capabilities for Any Need
New behavioral policies can be uploaded via the PoW blockchain, allowing Damage Nodes to dynamically evolve.
Behaviors can be triggered by:
On-chain conditions (such as receiving a Lightning payment for service execution).
Real-world events (via oracle integrations).
Direct requests from verified users.
Examples of Extensions:
Decentralized AI Defense: Nodes monitor AI-generated media for deepfake propaganda & censorship.
Physical Security Triggers: Nodes can integrate with smart devices (cameras, sensors) to execute real-world countermeasures.
Automated Asset Protection: Damage Nodes can trigger the release of cryptographic assets upon verifiable external threats.
Final Verdict: Damage Nodes as the Ultimate Autonomy & Defense Infrastructure
Transparent but Unstoppable → Verifiable execution prevents corruption or abuse.
Extensible but Controlled → The blockchain enforces behavior logic while allowing flexibility.
Decentralized but Coordinated → Nodes operate independently but can synchronize.
Adaptive but Immutable → Behaviors evolve, but security is absolute.
🔥 Damage Nodes are the next evolutionary step in technological sovereignty—combining decentralized verification, autonomous execution, and proactive counter-surveillance in a single unstoppable system.

2025-02-02 13:32:12本文原载于《CERN Courier》,是由欧洲核子研究中心(CERN,全称Conseil Européen pour la Recherche Nucléaire)出版的权威科学期刊,专注于报道全球物理学、技术及创新领域的前沿动态。以下正文内容是对全球开源开发者激励平台DoraHacks的创始人张剑南的专访报道,探讨了黑客松如何成为科技创新的重要推动力以及DoraHacks在其中扮演的角色。
万维网(World Wide Web)、人工智能(Artificial Intelligence)与量子计算(Quantum Computing)——这些划时代的技术有何共同之处?DoraHacks创始人张剑南认为,它们都源于“Hacks(黑客精神)”。“当万维网在欧洲核子研究中心(CERN)诞生时,它向我们证明了一件事:要想改变并提高人类的生活方式和工作效率,关键在于以创新的思维利用现有的技术以实现突破。”张剑南解释道,“如果总是从零开始,我们永远无法取得实质性的进步。这恰恰就是开源运动和黑客马拉松的核心价值。”
十年前,张剑南参与筹办了CERN Webfest 2013,这是一场致力于探索如何以创新方式运用技术来服务科学与社会的黑客马拉松活动。通过Webfest,张剑南不仅实现了编程技能与物理学知识的跨学科融合,还与来自世界各地、背景各异的hackers建立了持久深厚的联系。随着参与黑客松次数的增多,他的“黑客精神”愈发强烈,最终驱使他创立了自己的公司。2024年,张剑南重返Webfest,但这次他不再是参与者,而是作为DoraHacks的首席执行官来见证这场盛会。
黑客马拉松是一种持续数天的社交编程活动,具有高度的包容性和开放性——参与者无需学术机构或企业背景即可加入。这种特性吸引了众多才华横溢的个体参与其中。活动中,hackers以团队形式合作,结合各自的技能,通过软件、硬件或商业计划等来解决技术难题。这不仅让物理学家、计算机科学家、工程师和企业家齐聚一堂,各展所长,也让年轻的开发者们有机会突破传统研究框架,提升技能、积累作品集,并拓展职业人脉。
“如果你对某件事充满热情,就应该能够立即投入其中并全力以赴,”张剑南强调,“追求梦想并不需要特定的学历或背景。”
对于在某个领域刚起步的研究者来说,黑客松的意义远不止于技术挑战。它为进入一个研究或行业领域提供了另一种途径,弥合了学术理论与实际应用之间的鸿沟。很多由大学举办的黑客松往往能够吸引到企业的赞助,这些赞助除了作为奖金来激励开发者持续开发,也会用来租赁大型场馆,以容纳数百甚至上千名参与者。
“正是这些大规模的黑客松吸引了众多行业猎头和导师的关注,”张剑南解释道,“他们把这类活动看作他们的人才库。通过黑客松,参与者们能够与大公司的人直接交流,加速职业发展,同时也能在实践中提升他们的编程能力。”
在2010年代,张剑南经常在周末参加黑客松,这也成为他创业的基石。“我曾经坐在计算机科学学院的公共休息室里,埋头研究我的黑客项目。我的大多数朋友也是在那里认识的,”张剑南回忆道,“但后来我意识到,如果想做出真正伟大的东西,必须有效地组织人力与资金。然后我就开始‘逃课’,不去上计算机系的课程,而是偷偷溜进商学院的教室里。”张剑南常常在商学院的教室后排听课,一边听课一边谋划自己的创业计划。他每天都与同行交流,评估各种不同的商业模式。“在创业过程中,要把工程知识与商业理论结合起来思考,”他补充道,“这是比较有趣的一点,让整个过程也轻松了一些。”
然而,从科学研究转向创业并非易事。“创业初期必须亲力亲为,要自己去学习然后完成各种任务。”张剑南坦言,“好处是能够接触到许多新技能和新朋友,但同时也得强迫自己去做那些原本不擅长的事情。”
这种经历也反映了许多创业者的共同困境:选择自己从头学习新技能,还是寻找合适的创业伙伴然后把任务分配出去?可是找到值得信赖的合作伙伴也不是一件容易的事,错误的决策甚至可能阻碍公司的发展。因此,从一开始就明确公司的愿景和使命显得尤为重要。
“解决方案其实很简单,”张剑南表示,“重点是要投入足够多的时间,亲自完成关键里程碑,以确保产品真正具备可行性。只要有了明确的商业计划和愿景,就能获得来自各方的支持。”
去中心化的社区治理
很多黑客马拉松参与者在活动结束后就会放弃自己的项目,但张剑南创立DoraHacks的初衷并非如此。他希望为全球的黑客团队提供一个平台,让他们能够将创意转化为成熟产品。“我希望黑客马拉松不仅仅是一个招聘工具,”他解释道,“它更应该推动开源开发和去中心化的社区治理。比如现在,来自坦桑尼亚的黑客可以与美国的黑客团队远程协作,然后获得持续的支持,以开发出真正有影响力的产品。这种模式让技术领域变得更多样化,同时也能够让更多人接触到不同的领域。”
DoraHacks通过帮助组织者降低后勤成本,为参与者提供更可靠的资金支持机制,使黑客松超越学术机构的限制,吸引更多对创新充满热情的个体研究者参与。然后不断发展整个社区,让年轻一代的开发者、研究者们能够在自己的职业初期,接触到比以往更多的机遇和机会。
“商业模式正在发生根本的变化,”张剑南指出,黑客马拉松正在发展成为新兴技术的基石,尤其是在量子计算、区块链和人工智能等以开源形式起步的领域。“产品创造的过程将会迎来重大变革。未来的技术发展不再依赖于孤立封闭的产品开发,而是基于黑客们可以共同贡献的平台和基础设施。”
如今,黑客马拉松的意义已不仅限于编程或建立人脉——它们更关乎突破技术边界、创造有意义的解决方案,并开辟新的职业道路。黑客马拉松是创意孵化器,并且能够对这些创意产生持久的影响力。张剑南希望帮助这些创意变为现实。“未来创新的方式一定是协作完成的,是开源的,”他再次强调,“在传统社会环境里,企业的发展依赖于在闭源技术周围筑起的护城河,这种技术更新方式的效率低下且不容易实现。而真正创新的未来,将以开放平台技术为核心,让全球开发者能够在现有项目的基础上不断迭代更新。这样的开放协作精神正是Hacker Movement(开源极客运动)如此重要的原因。”

2025-01-30 23:35:39Sometimes I’m reading the Bible and see a connection and go off chasing a rabbit trail. I type up my idea to organize my thoughts and see if there is actual Biblical support for it. Although it feels a bit weird to share Biblical ideas that I’m not certain about, it also seems a waste of lots of work to not share my speculations. Feel free to give me feedback if you disagree, especially if you have Scripture or historical evidence showing I’m wrong.
In this case, I’ve seen a portion that seems to be prophecy about our future, but that doesn’t necessarily mean that this entire group of chapters is future predictions. Sometimes prophecy mixes events that happens soon after the prophecy with events that will not be fulfilled until the distant future (like prophecies about Jesus’s first and second comings). I try to be open about what ideas I feel I have strong Biblical evidence to support and when my ideas have some evidence, but not conclusive evidence. This is one of my more speculative posts, but I hope you will find it thought provoking.
I was recently reading Isaiah 18-22. I had always assumed these prophecies of warning were in reference to things that had happened in the distant past (not that I knew any particular historical fulfillment), but this time I saw some major parallels with Revelation.
Now behold, here comes a troop of riders, horsemen in pairs.” And one said, “Fallen, fallen is Babylon; And all the images of her gods are shattered on the ground.” (Isaiah 21:9) {emphasis mine}
From Revelation:
And another angel, a second one, followed, saying, “Fallen, fallen is Babylon the great, she who has made all the nations drink of the wine of the passion of her immorality.” (Revelation 14:8) {emphasis mine}
And he cried out with a mighty voice, saying, “Fallen, fallen is Babylon the great! She has become a dwelling place of demons and a prison of every unclean spirit, and a prison of every unclean and hateful bird. (Revelation 18:2) {emphasis mine}
Of course it is possible that Babylon and Babylon the great are parallel, but different nations, but the similarity of statement is hard to deny.
All you inhabitants of the world and dwellers on earth,\ As soon as a standard is raised on the mountains, you will see it,\ And as soon as the trumpet is blown, you will hear it. (Isaiah 18:3) {emphasis mine}
This passage talks about all inhabitants of the world seeing a standard raised. Until the past 20 years or so, this was not possible. Now that almost every person on earth has a smart phone, we can know what is going on around the world in real time. This passage also refers to “dwellers on earth” which is a phrase used numerous times in Revelation.
In Revelation 11, it speaks of the two witnesses who testify to Jesus and call down plagues on the earth. After their death:
And their dead bodies will lie in the street of the great city which mystically is called Sodom and Egypt, where also their Lord was crucified. Those from the peoples and tribes and tongues and nations will look at their dead bodies for three and a half days, and will not permit their dead bodies to be laid in a tomb. And those who dwell on the earth will rejoice over them and celebrate; and they will send gifts to one another, because these two prophets tormented those who dwell on the earth. (Revelation 11:8-10) {emphasis mine}
Both passages refer to those who dwell on the earth and both talk about every person on earth seeing what is happening. This doesn’t sound like a prophecy fulfilled in ancient times, but about a prophecy that could not be fulfilled until modern times.
If these prophecies are about the end times and if the end times are now or very soon, what could they be referring to? Isaiah 18 begins with:
Woe to the land of whirring wings\ along the rivers of Cush,\ which sends envoys by sea\ in papyrus boats over the water.\ Go, swift messengers,\ to a people tall and smooth-skinned,\ to a people feared far and wide,\ an aggressive nation of strange speech,\ whose land is divided by rivers. (Isaiah 18:1-2)
Cush was located where modern day Sudan is located on the western edge of the Red Sea. Right across the red sea is Yemen which has been involved in missile and drone strikes on ships in the Red Sea. Traditionally the “land of whirring wings” is interpreted to mean locusts, but could it be referring to modern technology like drones? Who is Cush sent to seek? Who are the people “over the water,” “tall1 and smooth-skinned,” “feared far and wide,” and “an aggressive nation of strange speech,\ whose land is divided by rivers.”? I wonder if it could be the US. The US is over the Atlantic Ocean, “feared far and wide,” “an aggressive nation of strange speech” (involved in the business of almost every nation on earth), and divided by the Mississippi River (and to a lesser extent the Missouri and Ohio Rivers). The US also likes to act as the world’s policeman and get involved in every international dispute in the world. If Sudan was in fear of attack by the Houthis in Yemen, it would be expected for the US to be called in and get involved.
At the end of this prophecy:
At that time gifts will be brought to the Lord Almighty\ from a people tall and smooth-skinned,\ from a people feared far and wide,\ an aggressive nation of strange speech,\ whose land is divided by rivers—\ the gifts will be brought to Mount Zion, the place of the Name of the Lord Almighty. (Isaiah 18:7)
This same nation will bring a gift to Mount Zion (Jerusalem/Israel). The US has been regularly giving Israel weapons to defend itself from attacks by the enemies around it. If this nation is the US, then this would make sense, especially with our change in leadership.
When I read Isaiah 19, it made me think of the Muslim Brotherhood takeover of Egypt starting in 2011.
“I will stir up Egyptian against Egyptian—\ brother will fight against brother,\ neighbor against neighbor,\ city against city,\ kingdom against kingdom.\ The Egyptians will lose heart,\ and I will bring their plans to nothing;\ they will consult the idols and the spirits of the dead,\ the mediums and the spiritists.\ I will hand the Egyptians over\ to the power of a cruel master,\ and a fierce king will rule over them,”\ declares the Lord, the Lord Almighty. (Isaiah 19:2-4)
The next part of this passage talks about the Nile drying up and the canals stinking and the fields becoming parched. I did a web search related to drought in Egypt and found an article about drought fears from 2020. The building of the Grand Ethiopia Renaissance Dam on the Blue Nile is causing a fear of major drought in Egypt. There are negotiations between Egypt, Sudan, and Ethiopia to deal with this, but it looks like an ongoing issue for Egypt. An interesting fact is that Ethiopia started building this dam in 2011 -- the same year of the Muslim Brother Hood overthrow of Egypt.
The biggest problem with my theory is Isaiah 20, which talks about Assyria leading Egypt and Cush (Sudan) away as captives. Assyria was located in what is currently Northern Iraq. It is hard to fathom Iraq conquering Egypt and Sudan. The area of Assyria did include a little bit of Turkey, which would be more believable as a conqueror.
Now we get back to the verses in Isaiah 21, which started this musing. First there is a description of terrorists attack:
A prophecy against the Desert by the Sea:
Like whirlwinds sweeping through the southland,\ an invader comes from the desert,\ from a land of terror.\ A dire vision has been shown to me:\ The traitor betrays, the looter takes loot.\ Elam, attack! Media, lay siege!\ I will bring to an end all the groaning she caused. (Isaiah 21:1-2)
Elam is the Eastern edge of Iraq on the Border of Iran and Media is in Iran. Could this be an attack from Iran that includes some of its Shia allies in Iraq? What kind of attack could it be – conventional or nuclear? Who are they attacking?
Look, here comes a man in a chariot\ with a team of horses.\ And he gives back the answer:\ ‘Babylon has fallen, has fallen.\ All the images of its gods\ lie shattered on the ground!’ ”\ My people who are crushed on the threshing floor,\ I tell you what I have heard\ from the Lord Almighty,\ from the God of Israel. (Isaiah 21:9-10)
In ancient times, Babylon was located in the location of modern Iraq, but if we look at the words “Babylon has fallen, has fallen,” and associate them with the almost identical words in Revelation, “Fallen, fallen is Babylon the great,” and we consider how Revelation also refers to “Mystery Babylon” then we are likely talking about an attack on a different nation. (Why would Babylon be a mystery if it was the same people in the same location? It would be a mystery if it was a country and peoples that didn’t exist at the time of the prophecy, but would have the spirit of Babylon in them.) If you take into account my arguments in “Speculation on Babylon the Great” and associate this nation with the people “over the water,” “tall and smooth-skinned,” “feared far and wide,” and “an aggressive nation of strange speech, whose land is divided by rivers.” then this could be an attack on the US (I’ll admit there is a fair amount of speculation here). Although the US has become quite anti-God and has been pushing a lot of evil around the world, it still has one of the largest populations of believers in the world. The statement “My people who are crushed on the threshing floor” also fits for the US.
I know some people won’t consider the possibility that the US could be Mystery Babylon or Babylon the Great because they can’t consider the US being an evil nation, but the US has been pushing many unbiblical ideas on the nations around the globe, like LGBTQ ideology and abortion. It is also possible I am looking too hard for my own country in the scriptures because if the US isn’t mentioned, then something has to happen to the US before the Tribulation occurs to make the US become unimportant in international affairs. We all have our biases.
I’d love to hear your thoughts on my speculations. I’d also like to hear whether people benefit from my speculations or prefer me to stick to the clear and more easily understood Bible passages and Bible truths.
Trust Jesus.\ \ your sister in Christ,
