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.

2025-01-04 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.

2024-09-06 17:46:11Hey Frens,
This is the Geyser team, coming at you with a spicy idea: a grant for proper journalism.
Issue: Journalism is broken. Independent journalism is emerging with the work of The Rage, Whitney Webb and so forth. They deal with issues like privacy, political corruption, economics, ESG, medicine and many other issues that are not discussed by mainstream media.
The problem is that not many people know about their work and there are very few grant programs that support their work.
Proposed Solution: Geyser would like to host a Grant supporting independent journalists using 'community voting mechanism'. See here for how Community Voting Grants work.
However, we need more companies to partner up and sponsor this initiative with us. Ideas of more sponsors: - Stacker news: SN has become a great repository of independent/indie journalism. I think they'd fit in great as sponsors for this type of grant. cc: @k00b - Bitesize media: A new independent media house that wants to focus on the signal Bitcoin brings to our world. They expressed interest already. - Bitcoin Magazine: might be interested as well in this effort.
Would love the community's feedback on this idea and propose additional thoughts!

2024-12-29 19:54:14Um dos padrões mais bem estabelecidos ao medir a opinião pública é que cada geração tende a seguir um caminho semelhante em termos de política e ideologia geral. Seus membros compartilham das mesmas experiências formativas, atingem os marcos importantes da vida ao mesmo tempo e convivem nos mesmos espaços. Então, como devemos entender os relatórios que mostram que a Geração Z é hiperprogressista em certos assuntos, mas surpreendentemente conservadora em outros?
A resposta, nas palavras de Alice Evans, pesquisadora visitante na Universidade de Stanford e uma das principais estudiosas do tema, é que os jovens de hoje estão passando por um grande divergência de gênero, com as jovens mulheres do primeiro grupo e os jovens homens do segundo. A Geração Z representa duas gerações, e não apenas uma.
Em países de todos os continentes, surgiu um distanciamento ideológico entre jovens homens e mulheres. Milhões de pessoas que compartilham das mesmas cidades, locais de trabalho, salas de aula e até casas, não veem mais as coisas da mesma maneira.
Nos Estados Unidos, os dados da Gallup mostram que, após décadas em que os sexos estavam distribuídos de forma relativamente equilibrada entre visões políticas liberais e conservadoras, as mulheres entre 18 e 30 anos são agora 30 pontos percentuais mais liberais do que os homens dessa faixa etária. Essa diferença surgiu em apenas seis anos.
A Alemanha também apresenta um distanciamento de 30 pontos entre homens jovens conservadores e mulheres jovens progressistas, e no Reino Unido, a diferença é de 25 pontos. Na Polônia, no ano passado, quase metade dos homens entre 18 e 21 anos apoiou o partido de extrema direita Confederation, em contraste com apenas um sexto das jovens mulheres dessa mesma idade.
Fora do Ocidente, há divisões ainda mais acentuadas. Na Coreia do Sul, há um enorme abismo entre homens e mulheres jovens, e a situação é semelhante na China. Na África, a Tunísia apresenta o mesmo padrão. Vale notar que em todos os países essa divisão drástica ocorre principalmente entre a geração mais jovem, sendo muito menos pronunciada entre homens e mulheres na faixa dos 30 anos ou mais velhos.
O movimento # MeToo foi o principal estopim, trazendo à tona valores feministas intensos entre jovens mulheres que se sentiram empoderadas para denunciar injustiças de longa data. Esse estopim encontrou especialmente terreno fértil na Coreia do Sul, onde a desigualdade de gênero é bastante visível e a misoginia explícita é comum. (palavras da Financial Times, eu só traduzi)
Na eleição presidencial da Coreia do Sul em 2022, enquanto homens e mulheres mais velhos votaram de forma unificada, os jovens homens apoiaram fortemente o partido de direita People Power, enquanto as jovens mulheres apoiaram o partido liberal Democratic em números quase iguais e opostos.
A situação na Coreia é extrema, mas serve como um alerta para outros países sobre o que pode acontecer quando jovens homens e mulheres se distanciam. A sociedade está dividida, a taxa de casamento despencou e a taxa de natalidade caiu drasticamente, chegando a 0,78 filhos por mulher em 2022, o menor número no mundo todo.
Sete anos após a explosão inicial do movimento # MeToo, a divergência de gênero em atitudes tornou-se autossustentável.
Dados das pesquisas mostram que em muitos países, as diferenças ideológicas vão além dessa questão específica. A divisão progressista-conservadora sobre assédio sexual parece ter causado ou pelo menos faz parte de um alinhamento mais amplo, em que jovens homens e mulheres estão se organizando em grupos conservadores e liberais em outros assuntos.
Nos EUA, Reino Unido e Alemanha, as jovens mulheres agora adotam posturas mais liberais sobre temas como imigração e justiça racial, enquanto grupos etários mais velhos permanecem equilibrados. A tendência na maioria dos países tem sido de mulheres se inclinando mais para a esquerda, enquanto os homens permanecem estáveis. No entanto, há sinais de que os jovens homens estão se movendo para a direita na Alemanha, tornando-se mais críticos em relação à imigração e se aproximando do partido de extrema direita AfD nos últimos anos.
Seria fácil dizer que tudo isso é apenas uma fase passageira, mas os abismos ideológicos apenas crescem, e os dados mostram que as experiências políticas formativas das pessoas são difíceis de mudar. Tudo isso é agravado pelo fato de que o aumento dos smartphones e das redes sociais faz com que os jovens homens e mulheres agora vivam em espaços separados e tenham culturas distintas.
As opiniões dos jovens frequentemente são ignoradas devido à baixa participação política, mas essa mudança pode deixar consequências duradouras, impactando muito mais do que apenas os resultados das eleições.

2024-06-14 17:53:20WRITTEN BY: ALEX MREMA
Europe awaits for 24 of its best nations to kick off her headline football tournament on the 14th of June. This edition of the tournament promises to showcase some spectacular football filled with style, flair and a uniqueness that is only found in Europe. Surprises, thrillers and fierceness is promised throughout the Euros- not to forget the wonderful and warm German hosts who are promised to provide the vibes in and around the country.On that note, I present my second article on the best games Germany has to offer throughout the group stages!
GROUP D GAME: POLAND VS NETHERLANDS DATE: 16th June 2024 TIME: 14:00 BST
Poland look to prove themselves on the European stage again after a shocking Euro 2020 that saw them finish last in their group with one point and six goals conceded. Coach Michal Probierz will look to the strength of his young and powerful midfield featuring Brighton’s Jakub Moder and Roma’s Nicola Zalewski while the experienced head of Piotr Zielenski is expected to be the headlight to this midfield’s vision. Robert Lewandowski and Wojciech Szczeny are expected to play with an extra chip on their shoulder as this is likely to be their last international tournament for Poland. However, this Dutch side is one lethal side on their day. They can make teams suffer both offensively and defensively plus they can control the midfield appropriately if the backs are not against the walls. Plus the Netherlands put on an impressive run in the 2022 World Cup only to crash out in devastating fashion. Under Ronald Koeman, they have put on some very impressive performances but the only hiccups have come in games against that are “better” than them (in terms of player quality) where they perform poorly. With Netherlands being wishy-washy, can they do enough to beat Poland? We’ll see!
GAME: NETHERLANDS VS FRANCE DATE: 21st June 2024 TIME: 20:00 BST
France are certainly THE side to fear in this tournament. They have everything and they ooze in class with all that they have from the keepers all the way down to the manager. This French side has the potential to win every game in this tournament. Undoubtedly, the return of the engine that is N’golo Kante is vital to this French squad as they look to make their midfield a well-oiled machine with the never-expiring and youthful trio of Rabiot, Tchuoameni and Camavinga partnering working with the experienced Kante. The only problem, is how Deschamps will intergrate Kante in the French in a manner that is smooth and equally provides an immediate click. This is what the Dutch will look to pounce on. Regardless of the result of their first game against Poland, this game is what will make or break their tournament as a loss will be possibly detrimental to their progress while a win will probably make progression ever so likely. Can Koeman’s squad pounce on Les Bleus gamble?
GAME: NETHERLANDS VS AUSTRIA DATE: 25th June 2024 TIME: 17:00 BST
Austria are a side that are able to do their bits. Ralf Ragnick has enforced a hustling and fighting spirit that makes his squad work to the very end-which credits why they have qualified as one of the 24 nations certain to rock Europe this summer. They play progressive,fun,attacking football and are a side that are fearless. The experienced figures of Marko Arnautovic,Michael Gregoristch and Konrad Laimer are key to the leadership of Das Team this summer as the status on main figurehead David Alaba remains unclear as he is out with an injury. Holland’s approach to this game will be interesting. Particularly on how they will view the aerial battle between van Dijk and Gregoristch and how direct Arnautovic is towards the rest of the defence. Les Oranjes also have the capabilites to throw a tactical masterclass that can throw Ragnick and his men overboard. Let’s not forget that this is the final group game, so alll can be to play for...tactics may be thrown out the window and it might just be a full on dog fight between the two nations- what we need!
GROUP E GAME: UKRAINE VS BELGIUM DATE: 26th June 2024 TIME: 17:00
Group E is probably the weakest one in the tournament (alongside Group C).But, that does not take away from some of the talent displayed in the group. As expected to be showcased when the fiery Red Devils of Belgium face off against The Blues and Yellows of Ukraine. This will be Belgium’s first tournament without the legendary Eden Hazard in their camp, however this squad has seen the rise of some extremely talented players namely, Amadou Onana, Charles de Ketelaere and Jeremy Doku that all -coincidently- reside from the English Premier League. Head coach Domenico Tedesco has managed to fit in a blend of youth and experience as Belgium says goodbye to their “first phase” golden generation players and welcome new generation players to renovate the aging squad.On the other side of the dugout, coach Sergiy Rebrov has brought a squad that is extremely pacey,physical,daring and fearless. These aspects are best described in players such as Matviyenko,Zincheko, Mykola Shaparenko,Mudryk,Yaremchuk plus La Liga top scorer and Round of 16 hero in Euro 2020- Artem Dobvyk. This Ukraine squad can bring the heat at any point in the game, even against the run of play- they did not play their best football in Euro 2020 but somehow ended as quarter-finalists, just let it sink in when they start playing their best football...
GROUP F GAME: PORTUGAL VS CZECH REPUBLIC DATE: 18th June 2024 TIME: 20:00 BST
Portugal are a squad that is star-studded throughout and are led by the man, the myth, the legend that is Cristiano Ronaldo who has the same drive to win as when he first landed in this tournament 2004. He is the all-time Euros top scorer and you should expect more goals from within the next four weeks of football. The somewhat fear-factor that strikes opponents is that this is a Portugal squad that can snatch goals from anywhere, even when Ronaldo has a silent game, they can get results from Goncalo Ramos, Bernado Silva, Rafael Leao, Bruno Fernandes... and the list goes on! Truly scary what Seleção das Quinas has in store. But the Lokomotiva has something to say and boy on their day can they make a statement, this squad’s physicality, progressive football and never-say-die attitude is what has gotten them results throughout their journey to the tournament. Players such as Schick,Hlozek,Soucek and Antonin Barak are vital for the Czech Republic and when they are called upon, they deliver- just ask the Dutch.
GAME: CZECH REPUBLIC VS TURKEY DATE: 26th June 2024 TIME: 20:00 BST
Turkey have underperformed in recent tournaments- with group stage exists in Euro 2016 as well as Euro 2020. They do appear to be a better organized squad nowdays and do not settle for less when it comes to working for a positive result. The Crescent Stars are a joyful side that carry an immense amount of pride for the badge on their jerseys and wear their hearts on their sleeves for every game, this passion can be a huge motivating factor as to how far they progress through the tournament. The talent that the Czech Republic possesses however, can kill off the Turkish party. They are side that comes in to take results like the way a bully eould steal candy from a baby, they just simply play their football and move on quietly but equally deadly. Can they be the party poopers against Turkey in their final group game?

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.

2025-01-18 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.

2025-01-13 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.

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.

Saving Lives and Preserving Health
Dwadzieścia Jeden a polish node in decentralised bitcoin communities network Twenty One, is proud to facilitate bitcoin fundraising for the biggest, non-governmental, non-profit, charity in Poland — The Great Orchestra of Christmas Charity.
For the past 31 years, GOCC continuously fundraises money for pediatric and elderly care in Poland. Each year, a culmination of the raise occurs during the last Sunday of January in the shape of The Grand Finale — a joyful day that when tens of thousands volunteers worldwide, especially kids and teenagers, go on the streets to gather money for the cause, giving donors hear-shaped stickers with logo of the foundation. If you're in Poland on that day, basically every person you'll meet on the street will proudly wear GOCC heart.
The same hear-shaped stickers can be seen in every hospital in Poland on thousands of high quality medical equipment bought by The Great Orchestra. There is not a single polish family that hasn't benefited in some way from this equipment, and it saved thousands of lives, especially the little ones.
32nd Grand Finale Goal
This year, 32rd Grand Finale will take place on 28th of January. The aim of the 32nd Grand Finale is post-pandemic lung diseases — the raised funds will be used to purchase equipment for children's and adults' respiratory units.
The Foundation plans to purchase:
-
equipment for diagnostic imaging, i.a. MRI and ultrasound equipment,
-
equipment for functional diagnosis, i.a. polysomnographs and portable spirometers,
-
equipment for endoscopic diagnosis, i.a. navigational bronchoscopy systems and bronchoscopes
-
equipment for rehabilitation - equipment for pulmonary rehabilitation used in the treatment of patients after lung transplantation
-
equipment for thoracic surgery, e.g. electrocoagulation systems and cryoprobes.

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.

2025-01-21 01:51:46Bitcoin: Um sistema de dinheiro eletrônico direto entre pessoas.
Satoshi Nakamoto
satoshin@gmx.com
www.bitcoin.org
Resumo
O Bitcoin é uma forma de dinheiro digital que permite pagamentos diretos entre pessoas, sem a necessidade de um banco ou instituição financeira. Ele resolve um problema chamado gasto duplo, que ocorre quando alguém tenta gastar o mesmo dinheiro duas vezes. Para evitar isso, o Bitcoin usa uma rede descentralizada onde todos trabalham juntos para verificar e registrar as transações.
As transações são registradas em um livro público chamado blockchain, protegido por uma técnica chamada Prova de Trabalho. Essa técnica cria uma cadeia de registros que não pode ser alterada sem refazer todo o trabalho já feito. Essa cadeia é mantida pelos computadores que participam da rede, e a mais longa é considerada a verdadeira.
Enquanto a maior parte do poder computacional da rede for controlada por participantes honestos, o sistema continuará funcionando de forma segura. A rede é flexível, permitindo que qualquer pessoa entre ou saia a qualquer momento, sempre confiando na cadeia mais longa como prova do que aconteceu.
1. Introdução
Hoje, quase todos os pagamentos feitos pela internet dependem de bancos ou empresas como processadores de pagamento (cartões de crédito, por exemplo) para funcionar. Embora esse sistema seja útil, ele tem problemas importantes porque é baseado em confiança.
Primeiro, essas empresas podem reverter pagamentos, o que é útil em caso de erros, mas cria custos e incertezas. Isso faz com que pequenas transações, como pagar centavos por um serviço, se tornem inviáveis. Além disso, os comerciantes são obrigados a desconfiar dos clientes, pedindo informações extras e aceitando fraudes como algo inevitável.
Esses problemas não existem no dinheiro físico, como o papel-moeda, onde o pagamento é final e direto entre as partes. No entanto, não temos como enviar dinheiro físico pela internet sem depender de um intermediário confiável.
O que precisamos é de um sistema de pagamento eletrônico baseado em provas matemáticas, não em confiança. Esse sistema permitiria que qualquer pessoa enviasse dinheiro diretamente para outra, sem depender de bancos ou processadores de pagamento. Além disso, as transações seriam irreversíveis, protegendo vendedores contra fraudes, mas mantendo a possibilidade de soluções para disputas legítimas.
Neste documento, apresentamos o Bitcoin, que resolve o problema do gasto duplo usando uma rede descentralizada. Essa rede cria um registro público e protegido por cálculos matemáticos, que garante a ordem das transações. Enquanto a maior parte da rede for controlada por pessoas honestas, o sistema será seguro contra ataques.
2. Transações
Para entender como funciona o Bitcoin, é importante saber como as transações são realizadas. Imagine que você quer transferir uma "moeda digital" para outra pessoa. No sistema do Bitcoin, essa "moeda" é representada por uma sequência de registros que mostram quem é o atual dono. Para transferi-la, você adiciona um novo registro comprovando que agora ela pertence ao próximo dono. Esse registro é protegido por um tipo especial de assinatura digital.
O que é uma assinatura digital?
Uma assinatura digital é como uma senha secreta, mas muito mais segura. No Bitcoin, cada usuário tem duas chaves: uma "chave privada", que é secreta e serve para criar a assinatura, e uma "chave pública", que pode ser compartilhada com todos e é usada para verificar se a assinatura é válida. Quando você transfere uma moeda, usa sua chave privada para assinar a transação, provando que você é o dono. A próxima pessoa pode usar sua chave pública para confirmar isso.
Como funciona na prática?
Cada "moeda" no Bitcoin é, na verdade, uma cadeia de assinaturas digitais. Vamos imaginar o seguinte cenário:
- A moeda está com o Dono 0 (você). Para transferi-la ao Dono 1, você assina digitalmente a transação com sua chave privada. Essa assinatura inclui o código da transação anterior (chamado de "hash") e a chave pública do Dono 1.
- Quando o Dono 1 quiser transferir a moeda ao Dono 2, ele assinará a transação seguinte com sua própria chave privada, incluindo também o hash da transação anterior e a chave pública do Dono 2.
- Esse processo continua, formando uma "cadeia" de transações. Qualquer pessoa pode verificar essa cadeia para confirmar quem é o atual dono da moeda.
Resolvendo o problema do gasto duplo
Um grande desafio com moedas digitais é o "gasto duplo", que é quando uma mesma moeda é usada em mais de uma transação. Para evitar isso, muitos sistemas antigos dependiam de uma entidade central confiável, como uma casa da moeda, que verificava todas as transações. No entanto, isso criava um ponto único de falha e centralizava o controle do dinheiro.
O Bitcoin resolve esse problema de forma inovadora: ele usa uma rede descentralizada onde todos os participantes (os "nós") têm acesso a um registro completo de todas as transações. Cada nó verifica se as transações são válidas e se a moeda não foi gasta duas vezes. Quando a maioria dos nós concorda com a validade de uma transação, ela é registrada permanentemente na blockchain.
Por que isso é importante?
Essa solução elimina a necessidade de confiar em uma única entidade para gerenciar o dinheiro, permitindo que qualquer pessoa no mundo use o Bitcoin sem precisar de permissão de terceiros. Além disso, ela garante que o sistema seja seguro e resistente a fraudes.
3. Servidor Timestamp
Para assegurar que as transações sejam realizadas de forma segura e transparente, o sistema Bitcoin utiliza algo chamado de "servidor de registro de tempo" (timestamp). Esse servidor funciona como um registro público que organiza as transações em uma ordem específica.
Ele faz isso agrupando várias transações em blocos e criando um código único chamado "hash". Esse hash é como uma impressão digital que representa todo o conteúdo do bloco. O hash de cada bloco é amplamente divulgado, como se fosse publicado em um jornal ou em um fórum público.
Esse processo garante que cada bloco de transações tenha um registro de quando foi criado e que ele existia naquele momento. Além disso, cada novo bloco criado contém o hash do bloco anterior, formando uma cadeia contínua de blocos conectados — conhecida como blockchain.
Com isso, se alguém tentar alterar qualquer informação em um bloco anterior, o hash desse bloco mudará e não corresponderá ao hash armazenado no bloco seguinte. Essa característica torna a cadeia muito segura, pois qualquer tentativa de fraude seria imediatamente detectada.
O sistema de timestamps é essencial para provar a ordem cronológica das transações e garantir que cada uma delas seja única e autêntica. Dessa forma, ele reforça a segurança e a confiança na rede Bitcoin.
4. Prova-de-Trabalho
Para implementar o registro de tempo distribuído no sistema Bitcoin, utilizamos um mecanismo chamado prova-de-trabalho. Esse sistema é semelhante ao Hashcash, desenvolvido por Adam Back, e baseia-se na criação de um código único, o "hash", por meio de um processo computacionalmente exigente.
A prova-de-trabalho envolve encontrar um valor especial que, quando processado junto com as informações do bloco, gere um hash que comece com uma quantidade específica de zeros. Esse valor especial é chamado de "nonce". Encontrar o nonce correto exige um esforço significativo do computador, porque envolve tentativas repetidas até que a condição seja satisfeita.
Esse processo é importante porque torna extremamente difícil alterar qualquer informação registrada em um bloco. Se alguém tentar mudar algo em um bloco, seria necessário refazer o trabalho de computação não apenas para aquele bloco, mas também para todos os blocos que vêm depois dele. Isso garante a segurança e a imutabilidade da blockchain.
A prova-de-trabalho também resolve o problema de decidir qual cadeia de blocos é a válida quando há múltiplas cadeias competindo. A decisão é feita pela cadeia mais longa, pois ela representa o maior esforço computacional já realizado. Isso impede que qualquer indivíduo ou grupo controle a rede, desde que a maioria do poder de processamento seja mantida por participantes honestos.
Para garantir que o sistema permaneça eficiente e equilibrado, a dificuldade da prova-de-trabalho é ajustada automaticamente ao longo do tempo. Se novos blocos estiverem sendo gerados rapidamente, a dificuldade aumenta; se estiverem sendo gerados muito lentamente, a dificuldade diminui. Esse ajuste assegura que novos blocos sejam criados aproximadamente a cada 10 minutos, mantendo o sistema estável e funcional.
5. Rede
A rede Bitcoin é o coração do sistema e funciona de maneira distribuída, conectando vários participantes (ou nós) para garantir o registro e a validação das transações. Os passos para operar essa rede são:
-
Transmissão de Transações: Quando alguém realiza uma nova transação, ela é enviada para todos os nós da rede. Isso é feito para garantir que todos estejam cientes da operação e possam validá-la.
-
Coleta de Transações em Blocos: Cada nó agrupa as novas transações recebidas em um "bloco". Este bloco será preparado para ser adicionado à cadeia de blocos (a blockchain).
-
Prova-de-Trabalho: Os nós competem para resolver a prova-de-trabalho do bloco, utilizando poder computacional para encontrar um hash válido. Esse processo é como resolver um quebra-cabeça matemático difícil.
-
Envio do Bloco Resolvido: Quando um nó encontra a solução para o bloco (a prova-de-trabalho), ele compartilha esse bloco com todos os outros nós na rede.
-
Validação do Bloco: Cada nó verifica o bloco recebido para garantir que todas as transações nele contidas sejam válidas e que nenhuma moeda tenha sido gasta duas vezes. Apenas blocos válidos são aceitos.
-
Construção do Próximo Bloco: Os nós que aceitaram o bloco começam a trabalhar na criação do próximo bloco, utilizando o hash do bloco aceito como base (hash anterior). Isso mantém a continuidade da cadeia.
Resolução de Conflitos e Escolha da Cadeia Mais Longa
Os nós sempre priorizam a cadeia mais longa, pois ela representa o maior esforço computacional já realizado, garantindo maior segurança. Se dois blocos diferentes forem compartilhados simultaneamente, os nós trabalharão no primeiro bloco recebido, mas guardarão o outro como uma alternativa. Caso o segundo bloco eventualmente forme uma cadeia mais longa (ou seja, tenha mais blocos subsequentes), os nós mudarão para essa nova cadeia.
Tolerância a Falhas
A rede é robusta e pode lidar com mensagens que não chegam a todos os nós. Uma transação não precisa alcançar todos os nós de imediato; basta que chegue a um número suficiente deles para ser incluída em um bloco. Da mesma forma, se um nó não receber um bloco em tempo hábil, ele pode solicitá-lo ao perceber que está faltando quando o próximo bloco é recebido.
Esse mecanismo descentralizado permite que a rede Bitcoin funcione de maneira segura, confiável e resiliente, sem depender de uma autoridade central.
6. Incentivo
O incentivo é um dos pilares fundamentais que sustenta o funcionamento da rede Bitcoin, garantindo que os participantes (nós) continuem operando de forma honesta e contribuindo com recursos computacionais. Ele é estruturado em duas partes principais: a recompensa por mineração e as taxas de transação.
Recompensa por Mineração
Por convenção, o primeiro registro em cada bloco é uma transação especial que cria novas moedas e as atribui ao criador do bloco. Essa recompensa incentiva os mineradores a dedicarem poder computacional para apoiar a rede. Como não há uma autoridade central para emitir moedas, essa é a maneira pela qual novas moedas entram em circulação. Esse processo pode ser comparado ao trabalho de garimpeiros, que utilizam recursos para colocar mais ouro em circulação. No caso do Bitcoin, o "recurso" consiste no tempo de CPU e na energia elétrica consumida para resolver a prova-de-trabalho.
Taxas de Transação
Além da recompensa por mineração, os mineradores também podem ser incentivados pelas taxas de transação. Se uma transação utiliza menos valor de saída do que o valor de entrada, a diferença é tratada como uma taxa, que é adicionada à recompensa do bloco contendo essa transação. Com o passar do tempo e à medida que o número de moedas em circulação atinge o limite predeterminado, essas taxas de transação se tornam a principal fonte de incentivo, substituindo gradualmente a emissão de novas moedas. Isso permite que o sistema opere sem inflação, uma vez que o número total de moedas permanece fixo.
Incentivo à Honestidade
O design do incentivo também busca garantir que os participantes da rede mantenham um comportamento honesto. Para um atacante que consiga reunir mais poder computacional do que o restante da rede, ele enfrentaria duas escolhas:
- Usar esse poder para fraudar o sistema, como reverter transações e roubar pagamentos.
- Seguir as regras do sistema, criando novos blocos e recebendo recompensas legítimas.
A lógica econômica favorece a segunda opção, pois um comportamento desonesto prejudicaria a confiança no sistema, diminuindo o valor de todas as moedas, incluindo aquelas que o próprio atacante possui. Jogar dentro das regras não apenas maximiza o retorno financeiro, mas também preserva a validade e a integridade do sistema.
Esse mecanismo garante que os incentivos econômicos estejam alinhados com o objetivo de manter a rede segura, descentralizada e funcional ao longo do tempo.
7. Recuperação do Espaço em Disco
Depois que uma moeda passa a estar protegida por muitos blocos na cadeia, as informações sobre as transações antigas que a geraram podem ser descartadas para economizar espaço em disco. Para que isso seja possível sem comprometer a segurança, as transações são organizadas em uma estrutura chamada "árvore de Merkle". Essa árvore funciona como um resumo das transações: em vez de armazenar todas elas, guarda apenas um "hash raiz", que é como uma assinatura compacta que representa todo o grupo de transações.
Os blocos antigos podem, então, ser simplificados, removendo as partes desnecessárias dessa árvore. Apenas a raiz do hash precisa ser mantida no cabeçalho do bloco, garantindo que a integridade dos dados seja preservada, mesmo que detalhes específicos sejam descartados.
Para exemplificar: imagine que você tenha vários recibos de compra. Em vez de guardar todos os recibos, você cria um documento e lista apenas o valor total de cada um. Mesmo que os recibos originais sejam descartados, ainda é possível verificar a soma com base nos valores armazenados.
Além disso, o espaço ocupado pelos blocos em si é muito pequeno. Cada bloco sem transações ocupa apenas cerca de 80 bytes. Isso significa que, mesmo com blocos sendo gerados a cada 10 minutos, o crescimento anual em espaço necessário é insignificante: apenas 4,2 MB por ano. Com a capacidade de armazenamento dos computadores crescendo a cada ano, esse espaço continuará sendo trivial, garantindo que a rede possa operar de forma eficiente sem problemas de armazenamento, mesmo a longo prazo.
8. Verificação de Pagamento Simplificada
É possível confirmar pagamentos sem a necessidade de operar um nó completo da rede. Para isso, o usuário precisa apenas de uma cópia dos cabeçalhos dos blocos da cadeia mais longa (ou seja, a cadeia com maior esforço de trabalho acumulado). Ele pode verificar a validade de uma transação ao consultar os nós da rede até obter a confirmação de que tem a cadeia mais longa. Para isso, utiliza-se o ramo Merkle, que conecta a transação ao bloco em que ela foi registrada.
Entretanto, o método simplificado possui limitações: ele não pode confirmar uma transação isoladamente, mas sim assegurar que ela ocupa um lugar específico na cadeia mais longa. Dessa forma, se um nó da rede aprova a transação, os blocos subsequentes reforçam essa aceitação.
A verificação simplificada é confiável enquanto a maioria dos nós da rede for honesta. Contudo, ela se torna vulnerável caso a rede seja dominada por um invasor. Nesse cenário, um atacante poderia fabricar transações fraudulentas que enganariam o usuário temporariamente até que o invasor obtivesse controle completo da rede.
Uma estratégia para mitigar esse risco é configurar alertas nos softwares de nós completos. Esses alertas identificam blocos inválidos, sugerindo ao usuário baixar o bloco completo para confirmar qualquer inconsistência. Para maior segurança, empresas que realizam pagamentos frequentes podem preferir operar seus próprios nós, reduzindo riscos e permitindo uma verificação mais direta e confiável.
9. Combinando e Dividindo Valor
No sistema Bitcoin, cada unidade de valor é tratada como uma "moeda" individual, mas gerenciar cada centavo como uma transação separada seria impraticável. Para resolver isso, o Bitcoin permite que valores sejam combinados ou divididos em transações, facilitando pagamentos de qualquer valor.
Entradas e Saídas
Cada transação no Bitcoin é composta por:
- Entradas: Representam os valores recebidos em transações anteriores.
- Saídas: Correspondem aos valores enviados, divididos entre os destinatários e, eventualmente, o troco para o remetente.
Normalmente, uma transação contém:
- Uma única entrada com valor suficiente para cobrir o pagamento.
- Ou várias entradas combinadas para atingir o valor necessário.
O valor total das saídas nunca excede o das entradas, e a diferença (se houver) pode ser retornada ao remetente como troco.
Exemplo Prático
Imagine que você tem duas entradas:
- 0,03 BTC
- 0,07 BTC
Se deseja enviar 0,08 BTC para alguém, a transação terá:
- Entrada: As duas entradas combinadas (0,03 + 0,07 BTC = 0,10 BTC).
- Saídas: Uma para o destinatário (0,08 BTC) e outra como troco para você (0,02 BTC).
Essa flexibilidade permite que o sistema funcione sem precisar manipular cada unidade mínima individualmente.
Difusão e Simplificação
A difusão de transações, onde uma depende de várias anteriores e assim por diante, não representa um problema. Não é necessário armazenar ou verificar o histórico completo de uma transação para utilizá-la, já que o registro na blockchain garante sua integridade.
10. Privacidade
O modelo bancário tradicional oferece um certo nível de privacidade, limitando o acesso às informações financeiras apenas às partes envolvidas e a um terceiro confiável (como bancos ou instituições financeiras). No entanto, o Bitcoin opera de forma diferente, pois todas as transações são publicamente registradas na blockchain. Apesar disso, a privacidade pode ser mantida utilizando chaves públicas anônimas, que desvinculam diretamente as transações das identidades das partes envolvidas.
Fluxo de Informação
- No modelo tradicional, as transações passam por um terceiro confiável que conhece tanto o remetente quanto o destinatário.
- No Bitcoin, as transações são anunciadas publicamente, mas sem revelar diretamente as identidades das partes. Isso é comparável a dados divulgados por bolsas de valores, onde informações como o tempo e o tamanho das negociações (a "fita") são públicas, mas as identidades das partes não.
Protegendo a Privacidade
Para aumentar a privacidade no Bitcoin, são adotadas as seguintes práticas:
- Chaves Públicas Anônimas: Cada transação utiliza um par de chaves diferentes, dificultando a associação com um proprietário único.
- Prevenção de Ligação: Ao usar chaves novas para cada transação, reduz-se a possibilidade de links evidentes entre múltiplas transações realizadas pelo mesmo usuário.
Riscos de Ligação
Embora a privacidade seja fortalecida, alguns riscos permanecem:
- Transações multi-entrada podem revelar que todas as entradas pertencem ao mesmo proprietário, caso sejam necessárias para somar o valor total.
- O proprietário da chave pode ser identificado indiretamente por transações anteriores que estejam conectadas.
11. Cálculos
Imagine que temos um sistema onde as pessoas (ou computadores) competem para adicionar informações novas (blocos) a um grande registro público (a cadeia de blocos ou blockchain). Este registro é como um livro contábil compartilhado, onde todos podem verificar o que está escrito.
Agora, vamos pensar em um cenário: um atacante quer enganar o sistema. Ele quer mudar informações já registradas para beneficiar a si mesmo, por exemplo, desfazendo um pagamento que já fez. Para isso, ele precisa criar uma versão alternativa do livro contábil (a cadeia de blocos dele) e convencer todos os outros participantes de que essa versão é a verdadeira.
Mas isso é extremamente difícil.
Como o Ataque Funciona
Quando um novo bloco é adicionado à cadeia, ele depende de cálculos complexos que levam tempo e esforço. Esses cálculos são como um grande quebra-cabeça que precisa ser resolvido.
- Os “bons jogadores” (nós honestos) estão sempre trabalhando juntos para resolver esses quebra-cabeças e adicionar novos blocos à cadeia verdadeira.
- O atacante, por outro lado, precisa resolver quebra-cabeças sozinho, tentando “alcançar” a cadeia honesta para que sua versão alternativa pareça válida.
Se a cadeia honesta já está vários blocos à frente, o atacante começa em desvantagem, e o sistema está projetado para que a dificuldade de alcançá-los aumente rapidamente.
A Corrida Entre Cadeias
Você pode imaginar isso como uma corrida. A cada bloco novo que os jogadores honestos adicionam à cadeia verdadeira, eles se distanciam mais do atacante. Para vencer, o atacante teria que resolver os quebra-cabeças mais rápido que todos os outros jogadores honestos juntos.
Suponha que:
- A rede honesta tem 80% do poder computacional (ou seja, resolve 8 de cada 10 quebra-cabeças).
- O atacante tem 20% do poder computacional (ou seja, resolve 2 de cada 10 quebra-cabeças).
Cada vez que a rede honesta adiciona um bloco, o atacante tem que "correr atrás" e resolver mais quebra-cabeças para alcançar.
Por Que o Ataque Fica Cada Vez Mais Improvável?
Vamos usar uma fórmula simples para mostrar como as chances de sucesso do atacante diminuem conforme ele precisa "alcançar" mais blocos:
P = (q/p)^z
- q é o poder computacional do atacante (20%, ou 0,2).
- p é o poder computacional da rede honesta (80%, ou 0,8).
- z é a diferença de blocos entre a cadeia honesta e a cadeia do atacante.
Se o atacante está 5 blocos atrás (z = 5):
P = (0,2 / 0,8)^5 = (0,25)^5 = 0,00098, (ou, 0,098%)
Isso significa que o atacante tem menos de 0,1% de chance de sucesso — ou seja, é muito improvável.
Se ele estiver 10 blocos atrás (z = 10):
P = (0,2 / 0,8)^10 = (0,25)^10 = 0,000000095, (ou, 0,0000095%).
Neste caso, as chances de sucesso são praticamente nulas.
Um Exemplo Simples
Se você jogar uma moeda, a chance de cair “cara” é de 50%. Mas se precisar de 10 caras seguidas, sua chance já é bem menor. Se precisar de 20 caras seguidas, é quase impossível.
No caso do Bitcoin, o atacante precisa de muito mais do que 20 caras seguidas. Ele precisa resolver quebra-cabeças extremamente difíceis e alcançar os jogadores honestos que estão sempre à frente. Isso faz com que o ataque seja inviável na prática.
Por Que Tudo Isso é Seguro?
- A probabilidade de sucesso do atacante diminui exponencialmente. Isso significa que, quanto mais tempo passa, menor é a chance de ele conseguir enganar o sistema.
- A cadeia verdadeira (honesta) está protegida pela força da rede. Cada novo bloco que os jogadores honestos adicionam à cadeia torna mais difícil para o atacante alcançar.
E Se o Atacante Tentar Continuar?
O atacante poderia continuar tentando indefinidamente, mas ele estaria gastando muito tempo e energia sem conseguir nada. Enquanto isso, os jogadores honestos estão sempre adicionando novos blocos, tornando o trabalho do atacante ainda mais inútil.
Assim, o sistema garante que a cadeia verdadeira seja extremamente segura e que ataques sejam, na prática, impossíveis de ter sucesso.
12. Conclusão
Propusemos um sistema de transações eletrônicas que elimina a necessidade de confiança, baseando-se em assinaturas digitais e em uma rede peer-to-peer que utiliza prova de trabalho. Isso resolve o problema do gasto duplo, criando um histórico público de transações imutável, desde que a maioria do poder computacional permaneça sob controle dos participantes honestos. A rede funciona de forma simples e descentralizada, com nós independentes que não precisam de identificação ou coordenação direta. Eles entram e saem livremente, aceitando a cadeia de prova de trabalho como registro do que ocorreu durante sua ausência. As decisões são tomadas por meio do poder de CPU, validando blocos legítimos, estendendo a cadeia e rejeitando os inválidos. Com este mecanismo de consenso, todas as regras e incentivos necessários para o funcionamento seguro e eficiente do sistema são garantidos.

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)

From the 13th of January 2024 the football world’s eyes will all converge on the Ivory Coast as 24 of Africa’s best football nations look to take each other on for the title of Africa’s best come 11th February. Though there is only going to be one winner, that doesn’t mean we aren’t promised exceptional football, shocks and players showcasing their razzle dazzle throughout the next 29 days. This article will focus on the players from each of the 24 competing nations who don’t get the spotlight they deserve but are certain to cause trouble.
IVORY COAST Name: Simon Adingra Age: 21 Club: Brighton and Hove Albion(England) Position: Winger The bright orange Ivorian jerseys are not the only thing that will catch your eye from this squad as the youthful, electrifying and pacey Brighton winger Simon Adingra is certainly bound to catch the interest of some during the tournament. His eye for goal and his turbo speed is bound to give trouble to any defender.
EQUATORIAL GUINEA Name: Saúl Coco Age: 24 Club: UD Las Palmas(Spain) Position: Center-Back Equatorial Guinea are not newcomers to the competition and are not going to be a pushover in a group that contains hosts Ivory Coast and the star-studded Nigeria. A player one must recognize from the Central African country is none other than Saul Coco. 6-foot-2 and a menace at the back, he will catch the eye of many particularly in his match up with the towering Bissau-Guinean players and of course Nigeria’s Victor Osimhen.
GUINEA-BISSAU Name: Fali Candé Age: 24 Club: FC Metz(France) Position: Centre-Back Like Equatorial Guinea, Guinea- Bissau come to the tournament with a familiar idea of what is expected. This is a nation known for putting up a challenge no matter what and are able to even pull a shock or two. If they are going to attract any wins in the tournament they will need a solid defense in their attack-heavy group, luckily for Guinea Bissau, they have Fali Cande who is one of the rocks at the back that Africa should have an eye on as he is aggressive and committed to keeping a clean sheet.
NIGERIA Name: Moses Simon Age: 28 Club: FC Nantes(France) Position: Winger Nigeria come in as one of the favourites to win it all and with a squad that has the African player of the year (Victor Osimhen) it’s hard to disagree that they are capable of delivering the cup back to Nigeria for the first time since 2013. A player that is sure to electrify the tournament is FC Nantes winger Moses Simon who shone in the last edition but had his time cut short after the Super Eagles shock defeat to Tunisia in the Round of 16. Now with their other attacking star (Victor Boniface) officially out of the tournament, will the Simon-Osimhen-Boniface attacking duo bear fruit for Nigeria?
CAPE VERDE Name: Jamiro Monteiro Age: 30 Club: San Jose Earthquakes(USA) Position: Center Midfield A man of experience and flair, Jamiro Monteiro is going to be a man lighting up the highlight reels throughout his time in the Ivory Coast. With a flair like Alex de Souza and an awareness equal to that of David Silva, Monteiro instantly sets himself as a man to watch in Cape Verde’s conquest to spice up the tournament.
EGYPT Name: Ahmed Fatouh Age: 25 Club: Zamalek(Egypt) Position: Left Back Fatouh has been described as the “Egyptian Marcelo” for his ability to excel in the attacking third of the pitch despite being a left back. His skill and drive towards making an impact upfront shall not blindside viewers that he can also do it defensively. This man is pivotal for the Egyptians in their quest for glory.
GHANA Name: Salis Abdul Samed Age: 23 Club: RC Lens(France) Position: Central Defensive Midfielder Entering AFCON 2023, the Black Stars of Ghana are a nation booming with talent mixed with just the right amount of experience. Looking to put away the demons of their last AFCON appearance and deliver their first trophy since 1980, Ghana are likely to turn to their midfield to take them all the way. Yes, Mohammed Kudus is in that midfield but a player that goes unnoticed in that midfield is Salis Abdul Samed. He is magnificent at stealing the ball from opponents in a clean manner, further, he is able to put Ghana in promising positions when he moves the ball up. He truly is the new generation player that Ghana needed to make their midfield a threat to opponents.
MOZAMBIQUE Name: Geny Catamo Age: 22 Club: Sporting CP (Portugal) Position: Winger The scouts should keep an eye out for this young talent. He manages to wriggle through spaces with his dribbling and also leave defenders in the dust when going one on one with them. Catamo carries forward the game easily and with purpose and a lucid hunger. Head coach Chiquinho Conde should put his trust in this young man to make Mozambique a threat in the tournament.
CAMEROON Name: François-Régis Mughe Age: 19 Club: Olympique de Marseille(France) Position: Winger The youngest player on this list is a special prospect. His strength and pace is bound to make any defender have a difficult time when going up against him. He can create something out of nothing when given playing time, Cameroon coach Rigobert Song should make him have a taste of the competition and he will be wowed by the talent he has in his hands.
THE GAMBIA Name: Ablie Jallow Age: 25 Club: FC Metz(France) Position: Winger Classy, calm and collected. These are the three words that can best be used to describe Gambia’s top scorer during qualifiers. He carries an aura that is simply impossible to ignore and he comes at defenders like a high speed train. He will look to be the main influence in The Gambia’s drive towards making another quarter final run like in the last edition of the tournament. Oh, don’t give him time and space to shoot because he will punish the keeper.
GUINEA Name: Amadou Diawara Age: 26 Club: RSC Anderlecht(Belgium) Position: Defensive Midfielder Composure must be this man's middle name. Once he has the ball it is not getting lost with him, he keeps the ball until he releases a pass -which on occasion are mighty sensational- despite being a defensive midfielder,he is capable of bringing up the ball to threatening positions; when Guinea are in trouble at the back he is there to clean up the mess. He is the real deal. He is Amadou Diawara.
SENEGAL Name: Ismail Jakobs Age: 26 Club: AS Monaco(France) Position: Left Back Senegal will look to make it to their third final in as many tournaments and at the same time retain their crown. A new feature to the Lions of Teranga side is left back Ismail Jakobs who is very quick and tends to join the attack. He does have a left foot capable of finding the back of the net but it’s his defensive recovery and ethic that magnifies him above some of the other modern day defenders. He is one the Senegal camp must protect from any injuries or suspensions as he is key for their progression in the Ivory Coast.
ALGERIA Name: Ramiz Zerrouki Age: 25 Club: Feyenoord(Netherlands) Position: Defensive Midfielder Africa should be proud to have this man playing in the upcoming AFCON tournament as he is the epitome of athleticism and command on the pitch. Based in the Netherlands, Zerrouki will stop at nothing to get the ball back on his feet and once he has the ball he is at peace again and can run the Algerian midfield operations with ease. He will look to make the Algerian midfield gel and spearhead The Desert Foxes into the knockout rounds after a disappointing run in the 2021 edition of the tournament.
ANGOLA Name: Gelson Dala Age: 27 Club: Al Wakrah(Qatar) Position: Center Forward This man ended qualifiers as Angola’s top scorer and is an electrifying center forward. He hustles for the ball every time one of his wingers has the ball on their feet or alternatively when the ball is in the box he will make use of it no matter what. He is Angola’s main man and should be on every manager’s list of the most dangerous players in the tournament.
BURKINA FASO Name: Stephane Aziz Ki Age: 27 Club: Young Africans(Tanzania) Position: Attacking Midfielder The Stallions are a nation capable of causing havoc in Ivory Coast with the snap of a finger, they have an impressive defensive foundation and contain plenty of attacking threats. A diamond within this attack is none other than Young Africans midfielder; Aziz Ki. He is strong on the ball, influential on the pitch and when given time and space to unleash a shot,he will make the opposing team pay. He hopes to get some playing time while at Ivory Coast and light up the tournament for his country.
MAURITANIA ** Name: Khadim Diaw Age: 25 Club: Horoya(Guinea) Position:** Left Back Khadim Diaw is more than your typical left back that is able to do it all on defense, he is a joy for attackers to use for the link up play. He has an excellent passing ability that can pick out any of the Mauritanian strikers in the box. He is certainly bound to be on coach Amir Abdou’s starting eleven.
MALI Name: Kamory Doumbia Age: 20 Club: Stade Brestois 29(France Position: Attacking Midfielder Fresh off scoring four goals(yes you read that right) four goals against FC Lorient in France, it looks impossible for young starlet Kamory Doumbia to not feature in the tournament. He is pacey, attentive and has an eye for goal which only adds to Mali’s firepower. Many should watch out for this Mali squad as they might go all the way due to their attacking firepower.
NAMIBIA Name: Peter Shalulile Age: 30 Club: Mamelodi Sundowns(South Africa) Position: Centre Forward One of Africa’s most dangerous strikers in recent years is Namibia’s very own.Shalulile stands at only five-foot-seven but he can leave a defense in shambles in little to no time as he is best friends with the net. He carries a variety of methods to make the net rifle and has done so a staggering 110 times in the Premier Soccer League in South Africa. Watch out for this man Africa.
SOUTH AFRICA Name: Teboho Mokoena Age: 26 Club: Mamelodi Sundowns(South Africa) Position: Center Midfielder A long-range specialist and a maestro in the midfield, Teboho Mokoena can impact the state of a game at any point he decides to do so. He has the game at the palm of his hands at all times and dictates it with his calm demeanour. In the dying seconds of the match, every opponent should make sure the ball doesn’t find him because if it does, it will probably be in the back of the net within the blink of an eye.
TUNISIA Name: Elias Achouri Age: 24 Club: FC Kobenhavn(Denmark) Position: Winger A confident winger who is capable of taking two to three defenders with him and will still come out of that situation with the ball still on his feet. Taking into account that he is 24, it appears to be the perfect time for Achouri to make a name for himself and the Eagles of Carthage in the Ivory Coast.
DR CONGO Name: Fiston Kalala Mayele Age: 29 Club: Pyramids FC(Egypt) Position: Center Forward The DR Congo attack line is heavily loaded with players hungry to make a name for themselves. One of them is Fiston Mayele who is based in Egypt. He spells trouble for defenders as he charges at them with nothing else in his mind but hitting the back of the net, he tends to catch others out with his ability to head the ball in a way that troubles the keeper greatly. If he manages to link correctly with the other strikers that Les Leopards have in their squad, then they will certainly be a team to watch in the tournament.
MOROCCO Name: Ismael Saibari Age: 22 Club: PSV Eindhoven(Netherlands) Position: Central Midfielder Part of the undefeated PSV squad that is yet to drop a point, Ismael Saibari has made his name known on the squad. His flair carries him through as a standout amongst the crowd. In this Moroccan team that is looking to build off their historic World Cup run, head coach Walid Regragui’s decision to grant this young prospect some time in the tournament is simply genius.
ZAMBIA Name: Clatous Chama Age: 32 Club: Simba Sports Club(Tanzania) Position: Central Midfielder The Chipolopolo look to run back their miracle of 2012 in this edition of the competition and will mostly play through their midfield. One of their key midfielders is Clatous Chama who is nicknamed “Mwamba wa Lusaka” which is Swahili for Rock of Lusaka. He is a machine in the frontline for his club and carries a great work ethic towards creating goals every time he plays. Beyond his goal scoring ability, Chama is very technically gifted and makes every situation count when he has the ball. Zambia are blessed to have him on their side.
TANZANIA Name: Tarryn Allarakhia Age: 26 Club: Wealdstone(England) Position: Central Midfielder The Taifa Stars look to shock the African continent in their AFCON 2023 campaign after disappointing campaigns in 1980 and 2019. Tanzania aims to use their hidden gem of a midfielder to the best of his ability to work on progressing the ball up the pitch. Though the Tanzanian stands at five-foot-seven, he is capable of keeping his balance every time he makes a darting run and more importantly,he is able to progress the ball up the field and win fouls in promising positions.In addition, he has sensational flair in his arsenal plus a great shot power and accuracy to his name. Keep your eyes out for this gem Africa!

2024-01-10 21:35:26WRITTEN BY: ALEX MREMA @npub1w4zrulscqraej2570gkazt0e7j0q3xq4437hnxjqfvcs59hq86fs9vnn4x
The whole of Africa anxiously waits for the continent’s headline tournament to kick off at the Olympic Stadium Ebimpé. This edition of AFCON features teams with talent, flair and a bottled-up hunger ready to fight for their nation to the very end. Like my most recent article that served as “part one” of the must watch games from groups A through C, this essay will look through groups D through F and what juicy encounters these groups have in store for Africa!
GROUP D
GAME: ALGERIA VS ANGOLA DATE: 15th January 2024 TIME: 20:00 BST Group D kicks off with an exciting encounter in which both sides are not entirely familiar with each other. With that, Les Fennecs are looking to put in a firm statement to show the whole of Africa that they are not the same lacklustre team that showed up to Cameroon in 2021.While Angola are looking to make it known that they are not a pushover in this tournament.
GAME: ALGERIA VS BURKINA FASO DATE: 20th January 2024 TIME: 14:00 BST The standout game of this group is one that can go both ways. Burkina Faso have a squad that is capable of going all the way to the finals, they’ve sent out the message several times in previous editions of the tournament that they are not underdogs and nothing close to that, rather they are confident and fearless squad ready to snatch a win from you with ease. Algeria on the other hand are looking to stop Les Étalons attacking threat from harming them while they also do what they do best- attack, attack, attack. Exciting encounter!
GROUP E
GAME: MALI VS SOUTH AFRICA DATE: 16th January 2024 TIME: 20:00 BST Mali have one of the most underrated squads coming to the Ivory Coast. They have a strong attacking unit and a solid midfield led by Tottenham Hotspurs star; Yves Bissouma, they are going to give the South African defence some trouble in this encounter. However, Bafana Bafana are also able to be a nuisance to the Mali defence as their no-joke attacking unit is designed to catch defences lacking especially with Percy Tau on the pitch.
GAME: TUNISIA VS MALI DATE: 20th January 2024 TIME: 20:00 BST A mouth-watering encounter that has some history after a blunder from the Zambian referee in their last AFCON encounter in Cameroon saw Janny Sikazwe blow the whistle for full time in the 86th minute! Nevermind that, Mali managed to collect the win and top their group. Tunisia are looking to set the record straight against the Malians in their quest to match their successes of AFCON 2004, which they won on home soil. If the Tunisians are looking to go all the way then this game is a must win for them to prove that they can take on the continent’ big dogs.
GAME: SOUTH AFRICA VS TUNISIA DATE: 24th January 2024 TIME: 17:00 BST Considering that this is the last game of the group stage, the Tunisians are bound to attack as much as they can against the Bafana Bafana defence that can be leaky at times. Though it must be said Tunisia’s attacking unit is an ageing one but has some sprinkles of youth here and there with the likes of Elias Achouri and Sayfallah Ltaief. With this, if South Africa do manage to stop the Tunisian attack, they are more than likely able to steal the game from them. And so this makes the clash a pretty unpredictable game on who’s going to take the three points .
GROUP F
GAME: D.R.C VS ZAMBIA DATE: 17th January 2024 TIME: 20:00 BST Zambia look to repeat their miracle of 2012 and go all the way. The Chipolopolo have a midfield unit that is able to keep the ball safely and also have an attacking unit that can score goals from nowhere, having put 3 past the Ivory Coast during qualifiers, this team is heavily underrated.Their first hurdle is none other than the Democratic Republic of Congo that carries a heavy loaded attacking unit ready to make defences regret for even trying to cope against them, Les Léopards are definitely a team to watch throughout the tournament because of their confident and exciting attacking element in their gameplay.
GAME: ZAMBIA VS TANZANIA DATE: 21st January 2024 TIME: 17:00 BST There is nothing better than a clash between two neighbours in the group stage. Stade de San Pedro is bound to cook up something sensational. The Taifa Stars squad frustrated opponents in the qualifiers with their concentrated defence plus having an attacking unit that would score and immediately join the defence in squeezing in narrow victories which eventually made them one of Africa’s 24 competing nations in the tournament. I mean, they only scored three goals during the qualifiers but are somehow in the tournament…Remarkable! But, Zambia’s attacking force during qualifiers was on fire raking 12 goals in their favour and having Leicester City star Patson Daka to lead the line, he already has 4 goals and 2 assists in 7 appearances all season and will look to carry this form to the Ivory Coast. This is a classic game of attack versus defence, keep your eye out for this game Africa!
GAME: MOROCCO VS D.R.C DATE: 21st January 2024 TIME: 14:00 BST The game of the group promises back and forth attacking football throughout. The history-making Morocco are tipped as one of the top sides to win the tournament come February 11th all due to being a well oiled machine with power in all sectors on the pitch and even on the bench! Star attackers like En-Nesyri, Ezzalzouli and Boufal aim to show the Congolese who is boss when they clash. However, Les Léopards are an established side and are not a side to mess with as their attacking options are there to make Hakimi and the rest of the Moroccan backline feel their wrath.

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.
- Erosion of Rights: Gradual acceptance of surveillance can lead to a significant reduction in personal freedoms over time.
Potential Technological Alternatives
Some suggest that it's possible to fight illegal content without undermining encryption:
- Metadata Analysis: Focusing on patterns of communication rather than content.
- Enhanced Reporting Mechanisms: Encouraging users to report illegal content voluntarily.
- Investing in Law Enforcement Capabilities: Strengthening traditional investigative methods without compromising digital security.
The technical community largely agrees that weakening encryption is not the solution:
- Consensus on Security: Strong encryption is essential for the safety and privacy of all internet users.
- Call for Dialogue: Technologists and privacy experts advocate for collaborative approaches that address security concerns without sacrificing fundamental rights.

@ a95c6243:d345522c
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.

2025-01-21 02:26:28A warrior does not fear chaos—he thrives in it. Life is a battlefield, and disorder is the forge in which strength, strategy, and resilience are tempered. Whether in the pursuit of victory in business, relationships, or personal conquest, chaos is an inevitable adversary. But within every storm lies an opportunity—an opening to strike, to evolve, and to dominate where others falter. Only those who embrace the struggle with unwavering resolve can turn uncertainty into their greatest weapon.
Understanding Chaos
Chaos is not the enemy; it is the proving ground. It manifests as upheaval, setbacks, and unexpected challenges, forcing warriors to sharpen their minds and steel their resolve.
- Disruption Breeds Innovation: In the heat of battle, new tactics emerge. When the known paths are obliterated, new strategies take form.
- Mindset Is Your Strongest Weapon: Chaos can either crush you or forge you into something stronger. The choice lies within your perception.
- Growth Is Forged in Adversity: The greatest warriors are those who embrace discomfort, wielding it to forge endurance and ingenuity.Seizing Opportunity Amidst Chaos
- Adaptability Is Strength
-
The warrior who can shift tactics swiftly gains the upper hand. Flexibility and awareness allow for swift and decisive action where others hesitate.
-
Chaos Fuels Creativity
-
In the heat of turmoil, the boldest ideas are born. Warriors do not cling to old ways; they adapt, overcome, and conquer.
-
Endings Are Just New Battles
- What seems like defeat is often a call to arms for greater conquests. Every setback is a chance to regroup and strike back with renewed vigor.
Harnessing Chaos for Victory
- Remain Steady Amid the Storm: Fear clouds judgment; clarity is power. Observe, assess, and act with precision. Opportunities reveal themselves to those who master control over their emotions.
- Strike First, Strike Hard: Do not merely react to chaos—command it. Take decisive actions that position you ahead of the pack.
- Exploit Weaknesses: Where others see insurmountable problems, a warrior sees openings and opportunities to advance.
Lessons from the Battlefields of History
Legends are not born in times of peace but in the crucible of chaos. From generals who turned the tide of war in moments of despair to entrepreneurs who built empires from ruin, history is a testament to those who harnessed disorder and emerged victorious.
Conclusion: Chaos Is the Warrior's Ally
Chaos is not to be feared but embraced. It is the ultimate test of will and strategy. A true warrior sees beyond the disorder, crafting victory from the wreckage. In every crisis lies the seed of triumph; in every conflict, the chance to rise.
When chaos surrounds you, stand firm, sharpen your sword, and remember—opportunity belongs to those with the courage to seize it.

2024-01-07 00:18:20WRITTEN BY: ALEX MREMA NOSTR @npub1w4zrulscqraej2570gkazt0e7j0q3xq4437hnxjqfvcs59hq86fs9vnn4x
AFCON 2023 kicks off in a couple days with 24 of Africa’s best taking each other on for the coveted prize. The journey will be long for some while others will have to cancel some of their hotel reservations in the Ivory Coast as their journey will end earlier than expected. Looking at the participating nations, we are assured of great games throughout the competition and even looking at the group stage itself, they’re games that are simply a must-watch. This article will deep dive into the games in the first three groups that promise to provide entertainment.
GROUP A
GAME: NIGERIA VS EQUATORIAL GUINEA DATE: 14th January 2024 TIME: 14:00 BST Equatorial Guinea are a side that carries no fear within their hearts and are always ready for a challenge. They are not newcomers at punishing a team for poor play and will look to catch the loaded Super Eagles squad lacking in order to pull off an early tournament surprise.
GAME: IVORY COAST VS NIGERIA DATE: 18th January 2024 TIME: 17:00 BST A clash of the heavyweights comes early on in the tournament with the Super Eagles taking on Les Éléphants at the Olympic Stadium of Ebimpé. The hosts have to be in tip top shape to not disappoint their home fans against their West African rivals. Nigeria on the other hand are expected to go all the way in the tournament and will use this as a test for what to expect in the knockout rounds should they progress.
GAME: EQUATORIAL GUINEA VS IVORY COAST DATE: 22nd January 2024 TIME: 17:00 BST The last round of group games doesn’t get more important than this. Depending on the situation in the group, this could be a win or go home situation for both nations involved. Expect hard, back-and-forth, old school fearless African football as each country will aim to send a message to the rest of the continent that their football is one not to mess with!
GROUP B
GAME: GHANA VS CAPE VERDE DATE: 14th January 2024 TIME: 20:00 BST This will be Ghana’s first AFCON game since their shambolic campaign in Cameroon. They will look to express themselves as a new and reformed nation with a fresh style capable of taking them deep into the tournament. Cape Verde on the other hand are not going to make it easy for the Ghanaians as they are capable of creating a mountain load of chances to trouble the Ghanaian defence and keeper.
GAME: EGYPT VS GHANA DATE: 18th January 2024 TIME: 20:00 BST The Pharaohs are a red hot squad who are capable of taking on any of the other 23 nations involved in the competition and Ghana is no exception to this. Egypt’s defensive excellence will be a task that is capable of frustrating the Ghanaians but will be able to provide a great game of high tactical brilliance. Tune in to this one!
GROUP C
GAME: SENEGAL VS GAMBIA DATE: 15th January 2024 TIME: 14:00 BST The Group of Death consists of nations that are capable of providing games that will leave us on the edge of our seats by the final whistle and this clash of West African neighbours is no exception. The Gambians were one of the surprise packages of the 2021 edition of the last tournament making it all the way to the quarter-finals. However, this is one huge hurdle The Scorpions have to overcome in their first game as they take on the defending champions in their first game. Senegal will be looking to make it to their third final in as many tournaments. This match is simply a must watch!
GAME: CAMEROON VS GUINEA DATE: 15th January 2024 TIME: 17:00 BST Cameroon look to get to the finals after falling short on home soil in the last edition,which they hosted. They start off their campaign against a Guinea side that plays with purpose and pride. Guinea don’t hold anything back when they step on the AFCON stage- no matter the circumstances against them they will show up and show out against any opponent. This confidence coupled with Cameroon’s determination to take the trophy home makes the perfect potion for a juicy first round encounter in Group C.
GAME: SENEGAL VS CAMEROON DATE: 19th January 2024 TIME: 17:00 BST The clash of the lions is undoubtedly the game of the group stage. The Lions of Teranga take on The Indomitable Lions looking to take revenge for their heartbreaking semi-final exit from the last edition via penalty shootouts that left the whole nation in tears. This game will have the Cameroonians carrying extra motivation in their hearts to take down the Senegalese with their blistering attack led by their skipper, the goal scoring machine: Vincent Aboubakar.
GAME: GUINEA VS GAMBIA DATE: 19th January 2024 TIME: 20:00 BST
This will likely be a must-win game for both of the nations in order to secure comfortability in matchday 3 which is essential for a group of this magnitude. Both nations have a desire for scoring goals and attacking fearlessly, almost making it a given that this game will be a back and forth encounter that will see each country put their blood, sweat and tears for the three points.
GAME: GAMBIA VS CAMEROON DATE: 23rd January 2024 TIME: 17:00 This clash can possibly determine both nations' fate in the tournament. The Scorpions of Gambia carry an attacking sting that can leave the Cameroonian defence in conflict once they get going, they really can take on Cameroon and even leave with all three points here. But, this is Cameroon we are talking about, they will be determined to give their all to assure fans that they are not going to slip up even once in their quest to the trophy.
GAME: GUINEA VS SENEGAL DATE: 23rd January 2024 TIME: 17:00 BST Like the Gambia v Cameroon encounter, this game will be the determining factor for both these nations in their chase for the trophy. Senegal’s chase to retain the trophy has to go through the resilient Guineans. This sets up for a mouth-watering tie that will make both camps play with their hearts on their sleeves.

2025-01-21 02:14:26Part Two Of Series on Mastering the Musca
Building on the foundational physical conditioning required to catch a Musca domestica mid-flight, the second pillar of mastery lies in the cultivation of patience, refined visual tracking, and the perception of time. The process transcends physical agility, diving into cognitive and perceptual skills that are as much about mental discipline as they are about muscle memory.
The Science of Patience and Observation
Patience is the cornerstone of fly-catching excellence. Research in attentional control emphasizes that prolonged focus on erratic and unpredictable targets trains the brain's ability to maintain sustained attention. The ability to remain calm and observant under pressure—waiting for the opportune moment to act—relies on the prefrontal cortex, which governs impulse control and decision-making.
This form of patience, often described in meditative practices, lowers cortisol levels and enhances neuroplasticity, allowing individuals to adapt to the seemingly chaotic flight patterns of flies. Athletes in this discipline develop an intuitive understanding of when to strike, a skill honed through repetitive practice and exposure to unpredictable stimuli.
Visual Tracking: Decoding the Fly’s Erratic Patterns
Flies exhibit highly unpredictable movements, characterized by abrupt shifts in speed and direction. This erratic trajectory, driven by their compound eyes and rapid wing beats, challenges the human visual system. Successful fly-catching requires the athlete to excel in smooth-pursuit eye movements and saccades, which are rapid eye movements that recalibrate focus on moving targets.
Studies in visual-motor integration highlight that tracking small, fast-moving objects enhances neural efficiency in the occipital and parietal lobes. These regions process spatial information and coordinate motor responses. High-level performers develop an acute ability to anticipate trajectories by identifying subtle cues in the fly’s movement, such as wing positioning or changes in velocity.
Predictive Timing and the Illusion of "Slowing Down Time"
One of the most remarkable phenomena in fly-catching is the perception of slowed time during critical moments. This effect, documented in high-performance sports and combat scenarios, is attributed to the brain's increased processing of sensory input during periods of heightened arousal. By compressing time through rapid neural computations, the brain allows individuals to act with extraordinary precision.
Predictive timing, governed by the cerebellum, is essential for this process. The cerebellum calculates the fly’s likely trajectory, enabling the hand to intercept the target even as it changes direction. Repeated practice strengthens the cerebellar circuits, creating a feedback loop that enhances accuracy and reaction speed.
Refining the Craft Through Research
Prominent studies in neuroscience and sports science provide insights into training methods for aspiring fly-catching athletes:
-
Dynamic Visual Acuity Training: Exercises such as tracking moving dots on a screen can improve the ability to focus on fast-moving objects.
-
Anticipatory Drills: Practicing with simulated erratic targets, such as drones or programmable devices, hones the predictive capabilities of the brain.
-
Mindfulness and Reaction Time: Meditation and mindfulness training have been shown to reduce reaction times by calming the nervous system and improving attentional focus.
-
Eye-Hand Coordination Tools: Devices like stroboscopic glasses create controlled visual disruptions, forcing the brain to adapt to incomplete information.
The Path to Mastery
The art of fly-catching merges the physical, cognitive, and perceptual domains into a singular skill set. Through rigorous training, practitioners learn to read the chaotic dance of the fly, anticipate its movements, and act with surgical precision. The process demands patience, discipline, and a commitment to understanding the intricate connection between body and mind.
As Australia continues to explore this unique and challenging sport, its athletes embody a profound lesson: true mastery is not merely about speed or strength but the harmony of mind and body in the face of chaos.

2025-01-20 20:32:23Not all coffee roasts are created equal. The way coffee is roasted significantly impacts its flavor, aroma, and overall quality. Let’s dive deeper into the differences between drum roasting and air roasting—and why air roasting might just change the way you experience coffee.
Drum Roasting: The Traditional Approach
Drum roasting involves placing coffee beans into a rotating drum that’s heated from below. This method has been around for centuries and is popular among many large-scale roasters. However, it comes with some challenges:
Uneven Heat Distribution: Beans rest against the hot drum surface, leading to inconsistent roasting. Some beans may scorch, while others roast unevenly.
Residual Chaff: The outer skin of the coffee bean, called chaff, remains in the drum during roasting. If not properly removed, it can burn and contribute to bitter or smoky flavors.
Slower Process: Drum roasting can take longer, which can risk over-roasting and muting the coffee’s unique flavor notes.
While drum roasting is widely used, it often requires an experienced hand to avoid these pitfalls and deliver a high-quality roast.
Air Roasting: The Modern Revolution Air roasting, also known as fluid-bed roasting, uses a stream of hot air to roast coffee beans. This method creates a perfectly balanced environment where beans are suspended and roasted evenly. The results? Pure, unadulterated flavor. Here’s why air roasting is superior:
Even Roasting: With no direct contact with hot surfaces, beans are roasted uniformly, ensuring consistent flavor throughout every batch. Cleaner Taste: Chaff is blown away during the roasting process, preventing it from burning and leaving behind off-putting bitterness. Enhanced Flavors: Air roasting preserves the coffee’s natural flavor notes, highlighting the bright, clean, and vibrant characteristics of each bean. Faster Roasting: The shorter roasting time minimizes over-cooking and delivers a fresher, more aromatic cup of coffee. Air roasting isn’t just a method—it’s an art. By focusing on the bean’s intrinsic qualities, it elevates your coffee experience to a whole new level.

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.

2025-01-20 20:03:28Mock Draft
Pick 6: CB/WR Travis Hunter Pick 37: DT Derrick Harmon Pick 68: QB Quinn Ewers Pick 73: OT Emery Jones Jr. Pick 106: DE Ashton Guillotte Pick 142: RB Dylan Sampson Pick 178: OG Jared Wilson Pick 212: LB Jamon Dumas-Johnson Pick 216: WR Antwane Wells Jr. Pick 222: S Rayuan Lane III
We're going with the very rare two-way prospect Travis Hunter as our first pick. Both CB and WR are positions of need, so he'll get a lot of opportunity to shine.
Then, the best player available at 37 was a DT, so we go defense heavy with the first two picks.
In the third round, we grab a QB and beef up the pass protection. From these mocks, it's looking like the third round is where we'll land a QB, whether that's Ewers or Dart (who was also still on the board and has a cooler name).

2025-01-20 19:53:37To Review Part 7 (https://stacker.news/items/824233/r/AndyAdvance)
Scoring rubric is as follows: 5 - This law promoted 360 degrees of freedom. Bitcoiners around the world would champion this 4 3 2 1 - This bill is something straight out the communist/socialist playbook very anti freedom. Leads to forever wars endless spending and bad wellbeing for the american people
Now a look at the third bill that became law. Public Law No: 111-294 (12/09/2010)
H.R.5566 - Animal Crush Video Prohibition Act of 2010
Source( https://www.congress.gov/bill/111th-congress/house-bill/5566?q=%7B%22search%22%3A%22lummis%22%7D&s=1&r=53)
The Bill in Summary:
Animal Crush Video Prohibition Act of 2010 - Amends the federal criminal code to revise the prohibition against depictions of animal cruelty to prohibit anyone from knowingly creating an animal crush video if: (1) such person intends or has reason to know that such video will be distributed in, or using a means or facility of, interstate or foreign commerce; or (2) such video is distributed in, or using a means or facility of, interstate or foreign commerce. Prohibits the sale, marketing, exchange, or distribution of such videos in interstate or foreign commerce.
Defines "animal crush video" as any photograph, motion picture, film, video or digital recording, or electronic image that: (1) depicts actual conduct in which one or more living non-human mammals, birds, reptiles, or amphibians is intentionally crushed, burned, drowned, suffocated, impaled, or otherwise subjected to serious bodily injury; and (2) is obscene.
Extends the applicability of this Act to a person selling, marketing, advertising, exchanging, distributing, or creating animal crush videos outside the United States if: (1) such person intends or has reason to know that the animal crush video will be transported into the United States or its territories or possessions; or (2) the video is so transported. Imposes a fine and/or prison term of up to seven years for violations of this Act.
Exempts from the application of this Act: (1) any visual depiction of customary and normal veterinary or agricultural husbandry practices, the slaughter of animals for food, or hunting, trapping, or fishing; and (2) good faith distribution of an animal crush video to a law enforcement agency or a third party for the sole purpose of determining if referral to a law enforcement agency is appropriate.
Provides for compliance of the budgetary effects of this Act with the Statutory Pay-As-You-Go Act of 2010.
The Score (3/5)
As a person who loves animals I am 100% on board with this bill. I know Bitcoiners are against censorship but evil exists in the world and people who abuse animals are absolute scum and should censored and punished. Torturing animals for fun and putting it on tape and video needs to be censored and people who produce this kind of content have a special place in hell
Some might say humans slaughter animals by the millions for food so why no allow this vile behavior to proposer? The answer is easy we need food to survive. Protein is a fundamental nutrient that all humans need to sustain life. Killing animals for food is necessary for humans to survive. I don't buy the vegan lifestyle and we all can live on plants and grains. Some people need the protein in meat so slaughtering animals makes sense.
I gave this a three because it is trying to bring some sort of morality to the American public. Sen. Lummis on this bill did right by the American people. I didn't give it a max score because to comply with this law some level of censorship is required which can be oppressive if abused by the government but this is far and away from a warmongering Neo-Con bill that pumps the military industrial complex's bags.
Total Score (20/40)
After seven bills Sen. Lummis has 20 points out of a total 20. That is good for 50% freedom score. Not bad Sen. Lummis.

2024-01-05 18:33:59SPORTSTR IS HERE...
Since my earliest days, sports has been my lifeblood. At just six years old, my mother introduced me to the world of swimming—a decision that set the course for an incredible journey. By the age of eleven, I proudly held the title of a national champion in the UK. That achievement ignited a fire within me—a passion for sports that has burned ever brighter as the years passed.
Throughout my career in sports, I've been blessed with experiences that have shaped me profoundly. But now, my focus is turning towards nurturing the talents of the next generation.
As my journey in Bitcoin continues to evolve, I've eagerly awaited the perfect opportunity to unite it with my love for Africa, sports and the next generation. That moment has arrived.
I see an incredible prospect—an opportunity to empower grassroots, amateur, and professional athletes from around the world, particularly those hailing from East Africa. With the fusion of #NOSTR and #Bitcoin, I envision SPORTSTR as a place where these remarkable talents can showcase their abilities and connect with a global audience.
One individual who embodies this passion for sports and the transformative power of Bitcoin is my nephew, Alex Mrema (⚡️alexmrema@blink.sv). He's not just a talented athlete; he's a writer whose passion for sports knows no bounds. He's witnessed my journey through the world of sports and seen how Bitcoin has seamlessly woven its way into my life. We have partnered to launch SPORTSTR as a place for him and I to create content about sport on NOSTR and receive value in the form of Bitcoin.
Today marks the launch of SPORTSTR—an initiative aimed at sharing compelling articles by young writers, sporting news, and exclusive interviews with athletes. Our ultimate goal? To introduce them and our audience to the world of Bitcoin and NOSTR, seamlessly integrating these innovative technologies into the realm of sports.
This, however, is just the beginning—a starting point for something truly orange, purple and remarkable.
MAN LIKE WHO?
MAN LIKE KWEKS!

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.

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.

Próximo passo é Criar um perfil.
Pressione o + botão de ação no canto inferior direito e selecione "Novo perfil" ou aberta no botão + adicionar novo perfil.
-
Selecione um nome de exibição
-
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.
https://link.storjshare.io/raw/jxqbqmur2lcqe2eym5thgz4so2ya/production/8f9df1372ec7e659180609afa48be22b12109ae5e1eda9ef1dc05c1325652507.MP4
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.
https://link.storjshare.io/raw/jvji25zclkoqcouni5decle7if7a/production/ee3de3540a3e3dca6e6e26d303e12c2ef892a5d7769029275b8b95ffc7468780.MP4
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 .
https://git.openprivacy.ca/cwtch.im/server
https://docs.openprivacy.ca/cwtch-security-handbook/server.html
Como posso desligar o Cwtch? O painel frontal do aplicativo possui um ícone do botão "Shutdown Cwtch" (com um 'X'). Pressionar este botão irá acionar uma caixa de diálogo e, na confirmação, o Cwtch será desligado e todos os perfis serão descarregados.
Suas doações podem fazer a diferença no projeto Cwtch? O Cwtch é um projeto dedicado a construir aplicativos que preservam a privacidade, oferecendo comunicação de grupo resistente a metadados.

2025-01-21 01:57:53The Lightning Network (LN), a layer-2 protocol designed to scale Bitcoin transactions, is a powerful innovation that combines the reliability of Bitcoin's blockchain with the speed and affordability of off-chain payment channels. For node operators, the Lightning Network represents more than just a technical endeavor; it is a gateway to reimagining global finance and fostering economic empowerment. Here, we’ll delve into the motivations, responsibilities, and ambitions of Lightning Network node operators in today’s rapidly evolving ecosystem.
The Role of a Node Operator
At its core, a Lightning Network node operator is a steward of Bitcoin's second layer. By running a node, operators help facilitate instant, low-cost payments across the network. These nodes act as routing hubs, allowing users to send payments without directly opening a channel with one another.
But being a node operator is more than maintaining a server. It requires careful channel management, liquidity provisioning, and routing efficiency. A well-managed node contributes to the overall health and capacity of the Lightning Network, making it more reliable and accessible.
Ambitions Driving Node Operators
-
Decentralized Financial Sovereignty Many operators are motivated by the vision of a decentralized financial future. By running a node, they actively participate in building a trustless and permissionless payment network. This aligns with Bitcoin's ethos of financial sovereignty, where users can transact freely without intermediaries.
-
Earning Yield on Bitcoin Holdings Lightning Network node operators can earn routing fees by efficiently managing payment channels. While these fees are modest compared to traditional investments, they provide a way to earn yield on Bitcoin holdings without surrendering custody or relying on centralized services.
-
Enhancing Network Resilience A robust and well-distributed network is essential for Bitcoin's long-term success. Node operators aim to enhance the resilience of the Lightning Network by ensuring sufficient liquidity and efficient routing, especially in underserved regions.
-
Promoting Bitcoin Adoption Lightning Network enables microtransactions and instant payments, making Bitcoin more practical for everyday use. Node operators see themselves as enablers of this adoption, supporting merchants, applications, and users by providing reliable payment infrastructure.
-
Exploring Business Opportunities Beyond fees, the Lightning Network opens up new business models. From hosting custodial wallets to offering Lightning-as-a-Service (LaaS) for developers, node operators are at the forefront of experimenting with innovative monetization strategies.
Challenges in the Path of Ambition
Running a Lightning Network node is not without its hurdles. Operators face several challenges:

2025-01-20 16:27:40I just finished the audio book read by Norm himself. I must say, if you love Norm you will love this book. I highly recommend the audio book. I don't want to spoil anything but the book is like sitting down with Norm and listening to him tell you stories. You never know what is true or false and if the whole thing IS the joke. I laughed out loud many times.

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.

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.

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.

2025-01-20 13:22:54I'm thinking about buying a small house or a plot of land in Morocco and living there. The amount I am willing to pay for this would be $10 000 - 30 000. How much might I liquidate into their fiat (MAD) bank account with a month or so without them freezing my account and god only knows what worse things them doing to me. I use robosats and never exceed the amount of 950 euro when selling Bitcoin. I have all my wealth in Bitcoin, no history of income over the last 5 years, no filing tax returns too. I am from the EU, residing in Spain. How has your experience with Morocco been? Can one open a bank account in Morocco without having a residence there?

2025-01-19 21:48:49The recent shutdown of TikTok in the United States due to a potential government ban serves as a stark reminder how fragile centralized platforms truly are under the surface. While these platforms offer convenience, a more polished user experience, and connectivity, they are ultimately beholden to governments, corporations, and other authorities. This makes them vulnerable to censorship, regulation, and outright bans. In contrast, Nostr represents a shift in how we approach online communication and content sharing. Built on the principles of decentralization and user choice, Nostr cannot be banned, because it is not a platform—it is a protocol.
PROTOCOLS, NOT PLATFORMS.
At the heart of Nostr's philosophy is user choice, a feature that fundamentally sets it apart from legacy platforms. In centralized systems, the user experience is dictated by a single person or governing entity. If the platform decides to filter, censor, or ban specific users or content, individuals are left with little action to rectify the situation. They must either accept the changes or abandon the platform entirely, often at the cost of losing their social connections, their data, and their identity.
What's happening with TikTok could never happen on Nostr. With Nostr, the dynamics are completely different. Because it is a protocol, not a platform, no single entity controls the ecosystem. Instead, the protocol enables a network of applications and relays that users can freely choose from. If a particular application or relay implements policies that a user disagrees with, such as censorship, filtering, or even government enforced banning, they are not trapped or abandoned. They have the freedom to move to another application or relay with minimal effort.
THIS IS POWERFUL.
Take, for example, the case of a relay that decides to censor specific content. On a legacy platform, this would result in frustration and a loss of access for users. On Nostr, however, users can simply connect to a different relay that does not impose such restrictions. Similarly, if an application introduces features or policies that users dislike, they can migrate to a different application that better suits their preferences, all while retaining their identity and social connections.
The same principles apply to government bans and censorship. A government can ban a specific application or even multiple applications, just as it can block one relay or several relays. China has implemented both tactics, yet Chinese users continue to exist and actively participate on Nostr, demonstrating Nostr's ability to resistant censorship.
How? Simply, it turns into a game of whack-a-mole. When one relay is censored, another quickly takes its place. When one application is banned, another emerges. Users can also bypass these obstacles by running their own relays and applications directly from their homes or personal devices, eliminating reliance on larger entities or organizations and ensuring continuous access.
AGAIN, THIS IS POWERUFL.
Nostr's open and decentralized design makes it resistant to the kinds of government intervention that led to TikTok's outages this weekend and potential future ban in the next 90 days. There is no central server to target, no company to regulate, and no single point of failure. (Insert your CEO jokes here). As long as there are individuals running relays and applications, users continue creating notes and sending zaps.
Platforms like TikTok can be silenced with the stroke of a pen, leaving millions of users disconnected and abandoned. Social communication should not be silenced so incredibly easily. No one should have that much power over social interactions.
Will we on-board a massive wave of TikTokers in the coming hours or days? I don't know.
TikTokers may not be ready for Nostr yet, and honestly, Nostr may not be ready for them either. The ecosystem still lacks the completely polished applications, tools, and services they’re accustomed to. This is where we say "we're still early". They may not be early adopters like the current Nostr user base. Until we bridge that gap, they’ll likely move to the next centralized platform, only to face another government ban or round of censorship in the future. But eventually, there will come a tipping point, a moment when they’ve had enough. When that time comes, I hope we’re prepared. If we’re not, we risk missing a tremendous opportunity to onboard people who genuinely need Nostr’s freedom.
Until then, to all of the Nostr developers out there, keep up the great work and keep building. Your hard work and determination is needed.

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.

2024-09-27 08:20:16Best viewed on Habla, YakiHonne or Highlighter.
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.

2025-01-19 17:48:02Einleitung\ \ Schwierige Dinge einfach zu erklären ist der Anspruch von ELI5 (explain me like I'm 5). Das ist in unserer hoch technisierten Welt dringend erforderlich, denn nur mit dem Verständnis der Technologien können wir sie richtig einsetzen und weiter entwickeln.\ Ich starte meine Serie mit Nostr, einem relativ neuen Internet-Protokoll. Was zum Teufel ist ein Internet-Protokoll? Formal beschrieben sind es internationale Standards, die dafür sorgen, dass das Internet seit über 30 Jahren ziemlich gut funktioniert. Es ist die Sprache, in der sich die Rechner miteinander unterhalten und die auch Sie täglich nutzen, vermutlich ohne es bewusst wahrzunehmen. http(s) transportiert ihre Anfrage an einen Server (z.B. Amazon), und html sorgt dafür, dass aus den gelieferten Daten eine schöne Seite auf ihrem Bildschirm entsteht. Eine Mail wird mit smtp an den Mailserver gesendet und mit imap von ihm abgerufen, und da alle den Standard verwenden, funktioniert das mit jeder App auf jedem Betriebssystem und mit jedem Mail-Provider. Und mit einer Mail-Adresse wie roland@pareto.space können sie sogar jederzeit umziehen, egal wohin. Cool, das ist state of the art! Aber warum funktioniert das z.B. bei Chat nicht, gibt es da kein Protokoll? Doch, es heißt IRC (Internet Relay Chat → merken sie sich den Namen), aber es wird so gut wie nicht verwendet. Die Gründe dafür sind nicht technischer Natur, vielmehr wurden mit Apps wie Facebook, Twitter, WhatsApp, Telegram, Instagram, TikTok u.a. bewusst Inkompatibilitäten und Nutzerabhängigkeiten geschaffen um Profite zu maximieren.
Warum Nostr?
Da das Standard-Protokoll nicht genutzt wird, hat jede App ihr eigenes, und wir brauchen eine handvoll Apps um uns mit allen Bekannten auszutauschen. Eine Mobilfunknummer ist Voraussetzung für jedes Konto, damit können die App-Hersteller die Nutzer umfassend tracken und mit dem Verkauf der Informationen bis zu 30 USD je Konto und Monat verdienen. Der Nutzer ist nicht mehr Kunde, er ist das Produkt! Der Werbe-SPAM ist noch das kleinste Problem bei diesem Geschäftsmodell. Server mit Millionen von Nutzerdaten sind ein “honey pot”, dementsprechend oft werden sie gehackt und die Zugangsdaten verkauft. 2024 wurde auch der Twitter-Account vom damaligen Präsidenten Joe Biden gehackt, niemand wusste mehr wer die Nachrichten verfasst hat (vorher auch nicht), d.h. die Authentizität der Inhalte ist bei keinem dieser Anbieter gewährleistet. Im selben Jahr wurde der Telegram-Gründer in Frankreich in Beugehaft genommen, weil er sich geweigert hatte Hintertüren in seine Software einzubauen. Nun kann zum Schutz "unserer Demokratie” praktisch jeder mitlesen, was sie mit wem an Informationen austauschen, z.B. darüber welches Shampoo bestimmte Politiker verwenden.
Und wer tatsächlich glaubt er könne Meinungsfreiheit auf sozialen Medien praktizieren, findet sich schnell in der Situation von Donald Trump wieder (seinerzeit amtierender Präsident), dem sein Twitter-Konto 2021 abgeschaltet wurde (Cancel-Culture). Die Nutzerdaten, also ihr Profil, ihre Kontakte, Dokumente, Bilder, Videos und Audiofiles - gehören ihnen ohnehin nicht mehr sondern sind Eigentum des Plattform-Betreibers; lesen sie sich mal die AGB's durch. Aber nein, keine gute Idee, das sind hunderte Seiten und sie werden permanent geändert. Alle nutzen also Apps, deren Technik sie nicht verstehen, deren Regeln sie nicht kennen, wo sie keine Rechte haben und die ihnen die Resultate ihres Handelns stehlen. Was würde wohl der Fünfjährige sagen, wenn ihm seine ältere Schwester anbieten würde, alle seine Spielzeuge zu “verwalten” und dann auszuhändigen wenn er brav ist? “Du spinnst wohl”, und damit beweist der Knirps mehr Vernunft als die Mehrzahl der Erwachsenen. \ \ Resümee: keine Standards, keine Daten, keine Rechte = keine Zukunft!
\ Wie funktioniert Nostr?
Die Entwickler von Nostr haben erkannt dass sich das Server-Client-Konzept in ein Master-Slave-Konzept verwandelt hatte. Der Master ist ein Synonym für Zentralisierung und wird zum “single point of failure”, der zwangsläufig Systeme dysfunktional macht. In einem verteilten Peer2Peer-System gibt es keine Master mehr sondern nur gleichberechtigte Knoten (Relays), auf denen die Informationen gespeichert werden. Indem man Informationen auf mehreren Relays redundant speichert, ist das System in jeglicher Hinsicht resilienter. Nicht nur die Natur verwendet dieses Prinzip seit Jahrmillionen erfolgreich, auch das Internet wurde so konzipiert (das ARPAnet wurde vom US-Militär für den Einsatz in Kriegsfällen unter massiven Störungen entwickelt). Alle Nostr-Daten liegen auf Relays und der Nutzer kann wählen zwischen öffentlichen (zumeist kostenlosen) und privaten Relays, z.B. für geschlossene Gruppen oder zum Zwecke von Daten-Archivierung. Da Dokumente auf mehreren Relays gespeichert sind, werden statt URL's (Locator) eindeutige Dokumentnamen (URI's = Identifier) verwendet, broken Links sind damit Vergangenheit und Löschungen / Verluste ebenfalls.\ \ Jedes Dokument (Event genannt) wird vom Besitzer signiert, es ist damit authentisch und fälschungssicher und kann nur vom Ersteller gelöscht werden. Dafür wird ein Schlüsselpaar verwendet bestehend aus privatem (nsec) und öffentlichem Schlüssel (npub) wie aus der Mailverschlüsselung (PGP) bekannt. Das repräsentiert eine Nostr-Identität, die um Bild, Namen, Bio und eine lesbare Nostr-Adresse ergänzt werden kann (z.B. roland@pareto.space ), mehr braucht es nicht um alle Ressourcen des Nostr-Ökosystems zu nutzen. Und das besteht inzwischen aus über hundert Apps mit unterschiedlichen Fokussierungen, z.B. für persönliche verschlüsselte Nachrichten (DM → OxChat), Kurznachrichten (Damus, Primal), Blogbeiträge (Pareto), Meetups (Joinstr), Gruppen (Groups), Bilder (Olas), Videos (Amethyst), Audio-Chat (Nostr Nests), Audio-Streams (Tunestr), Video-Streams (Zap.Stream), Marktplätze (Shopstr) u.v.a.m. Die Anmeldung erfolgt mit einem Klick (single sign on) und den Apps stehen ALLE Nutzerdaten zur Verfügung (Profil, Daten, Kontakte, Social Graph → Follower, Bookmarks, Comments, etc.), im Gegensatz zu den fragmentierten Datensilos der Gegenwart.\ \ Resümee: ein offener Standard, alle Daten, alle Rechte = große Zukunft!
\ Warum ist Nostr die Zukunft des Internet?
“Baue Dein Haus nicht auf einem fremden Grundstück” gilt auch im Internet - für alle App-Entwickler, Künstler, Journalisten und Nutzer, denn auch ihre Daten sind werthaltig. Nostr garantiert das Eigentum an den Daten, und überwindet ihre Fragmentierung. Weder die Nutzung noch die kreativen Freiheiten werden durch maßlose Lizenz- und Nutzungsbedingungen eingeschränkt. Aus passiven Nutzern werden durch Interaktion aktive Teilnehmer, Co-Creatoren in einer Sharing-Ökonomie (Value4Value). OpenSource schafft endlich wieder Vertrauen in die Software und ihre Anbieter. Offene Standards ermöglichen den Entwicklern mehr Kooperation und schnellere Entwicklung, für die Anwender garantieren sie Wahlfreiheit. Womit wir letztmalig zu unserem Fünfjährigen zurückkehren. Kinder lieben Lego über alles, am meisten die Maxi-Box “Classic”, weil sie damit ihre Phantasie im Kombinieren voll ausleben können. Erwachsene schenken ihnen dann die viel zu teuren Themenpakete, mit denen man nur eine Lösung nach Anleitung bauen kann. “Was stimmt nur mit meinen Eltern nicht, wann sind die denn falsch abgebogen?" fragt sich der Nachwuchs zu Recht. Das Image lässt sich aber wieder aufpolieren, wenn sie ihren Kindern Nostr zeigen, denn die Vorteile verstehen sogar Fünfjährige.
\ Das neue Internet ist dezentral. Das neue Internet ist selbstbestimmt. Nostr ist das neue Internet.

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.

2024-05-15 10:08:47KRIS menjamin semua golongan masyarakat mendapatkan perlakuan sama dari rumah sakit, baik pelayanan medis maupun nonmedis.
Demi memberikan peningkatan kualitas layanan kesehatan kepada masyarakat, pemerintah baru saja mengeluarkan Peraturan Presiden (Perpres) nomor 59 tahun 2024 tentang Jaminan Kesehatan. Melalui perpres itu, Presiden Joko Widodo (Jokowi) telah menghapus perbedaan kelas layanan 1, 2, dan 3 dalam Badan Penyelenggara Jaminan Sosial atau BPJS Kesehatan.
Layanan berbasis kelas itu diganti dengan KRIS (Kelas Rawat Inap Standar). Berkaitan dengan lahirnya Perpres 59/2024 tentang Perubahan Ketiga atas Perpres 82/2018 tentang Jaminan Kesehatan, Presiden Joko Widodo telah memerintahkan seluruh rumah sakit yang bekerja sama dengan BPJS Kesehatan melaksanakannya.
Kebijakan baru itu mulai berlaku per 8 Mei 2024 dan paling lambat 30 Juni 2025. Dalam jangka waktu tersebut, rumah sakit dapat menyelenggarakan sebagian atau seluruh pelayanan rawat inap berdasarkan KRIS sesuai dengan kemampuan rumah sakit.
Lantas apa yang menjadi pembeda dari sisi layanan dengan layanan rawat inap sesuai Perpres 59/2024? Dahulu sistem layanan rawat BPJS Kesehatan dibagi berdasarkan kelas yang dibagi masing-masing kelas 1, 2, dan 3. Namun, melalui perpres, layanan kepada masyarakat tidak dibedakan lagi.
Pelayanan rawat inap yang diatur dalam perpres itu--dikenal dengan nama KRIS—menjadi sistem baru yang digunakan dalam pelayanan rawat inap BPJS Kesehatan di rumah sakit-rumah sakit. Dengan KRIS, semua golongan masyarakat akan mendapatkan perlakuan yang sama dari rumah sakit, baik dalam hal pelayanan medis maupun nonmedis.
Dengan lahirnya Perpres 59/2024, tarif iuran BPJS Kesehatan pun juga akan berubah. Hanya saja, dalam Perpres itu belum dicantumkan secara rinci ihwal besar iuran yang baru. Besaran iuran baru BPJS Kesehatan itu sesuai rencana baru ditetapkan pada 1 Juli 2025.
“Penetapan manfaat, tarif, dan iuran sebagaimana dimaksud ditetapkan paling lambat tanggal 1 Juli 2025,” tulis aturan tersebut, dikutip Senin (13/5/2024).
Itu artinya, iuran BPJS Kesehatan saat ini masih sama seperti sebelumnya, yakni sesuai dengan kelas yang dipilih. Namun perpres itu tetap berlaku sembari menanti lahirnya peraturan lanjutan dari perpres tersebut.
Kesiapan Rumah Sakit
Berkaitan dengan lahirnya kebijakan layanan kesehatan tanpa dibedakan kelas lagi, Kementerian Kesehatan (Kemenkes) menegaskan mayoritas rumah sakit di Indonesia siap untuk menjalankan layanan KRIS untuk pasien BPJS Kesehatan.
Kesiapan itu diungkapkan oleh Dirjen Pelayanan Kesehatan Kemenkes Azhar Jaya. “Survei kesiapan RS terkait KRIS sudah dilakukan pada 2.988 rumah sakit dan yang sudah siap menjawab isian 12 kriteria ada sebanyak 2.233 rumah sakit,” ujar Azhar.
Sebagai informasi, KRIS adalah pengganti layanan Kelas 1, 2, dan 3 BPJS Kesehatan yang bertujuan untuk memberikan layanan kesehatan secara merata tanpa melihat besaran iurannya.
Melalui KRIS, rumah sakit perlu menyiapkan sarana dan prasarana sesuai dengan 12 kriteria kelas rawat inap standar secara bertahap. Apa saja ke-12 kriteria KRIS itu?
Sesuai bunyi Pasal 46A Perpres 59/2024, disyaratkan kriteria fasilitas perawatan dan pelayanan rawat inap KRIS meliputi komponen bangunan yang digunakan tidak boleh memiliki tingkat porositas yang tinggi serta terdapat ventilasi udara dan kelengkapan tidur.
Demikian pula soal pencahayaan ruangan. Perpres itu juga mengatur pencahayaan ruangan buatan mengikuti kriteria standar 250 lux untuk penerangan dan 50 lux untuk pencahayaan tidur, temperature ruangan 20--26 derajat celcius.
Tidak hanya itu, layanan rawat inap berdasarkan perpres itu mensyaratkan fasilitas layanan yang membagi ruang rawat berdasarkan jenis kelamin pasien, anak atau dewasa, serta penyakit infeksi atau noninfeksi.
Selain itu, kriteria lainnya adalah keharusan bagi penyedia layanan untuk mempertimbangkan kepadatan ruang rawat dan kualitas tempat tidur, penyediaan tirai atau partisi antartempat tidur, kamar mandi dalam ruangan rawat inap yang memenuhi standar aksesibilitas, dan menyediakan outlet oksigen.
Selain itu, kelengkapan tempat tidur berupa adanya dua kotak kontak dan nurse call pada setiap tempat tidur dan adanya nakas per tempat tidur. Kepadatan ruang rawat inap maksimal empat tempat tidur dengan jarak antara tepi tempat tidur minimal 1,5 meter.
Tirai/partisi dengan rel dibenamkan menempel di plafon atau menggantung. Kamar mandi dalam ruang rawat inap serta kamar mandi sesuai dengan standar aksesibilitas dan outlet oksigen.
Azhar menjamin, Kemenkes akan menjalankan hal tersebut sesuai dengan tupoksi yang ada. “Tentu saja kami akan bekerja sama dengan BPJS Kesehatan dalam implementasi dan pengawasannya di lapangan,” ujar Azhar.
Berkaitan dengan perpres jaminan kesehatan itu, Direktur Utama BPJS Kesehatan Ghufron Mukti menilai, perpres tersebut berorientasi pada penyeragaman kelas rawat inap yang mengacu pada 12 kriteria. "Bahwa perawatan ada kelas rawat inap standar dengan 12 kriteria, untuk peserta BPJS, maka sebagaimana sumpah dokter tidak boleh dibedakan pemberian pelayan medis atas dasar suku, agama, status sosial atau beda iurannya," ujarnya.
Jika ada peserta ingin dirawat pada kelas yang lebih tinggi, kata Ghufron, maka diperbolehkan selama hal itu dipengaruhi situasi nonmedis. Hal itu disebutkan dalam Pasal 51 Perpres Jaminan Kesehatan diatur ketentuan naik kelas perawatan.
Menurut pasal tersebut, naik kelas perawatan dilakukan dengan cara mengikuti asuransi kesehatan tambahan atau membayar selisih antara biaya yang dijamin oleh BPJS Kesehatan dengan biaya yang harus dibayar akibat peningkatan pelayanan.
Selisih antara biaya yang dijamin oleh BPJS Kesehatan dengan biaya pelayanan dapat dibayar oleh peserta bersangkutan, pemberi kerja, atau asuransi kesehatan tambahan.
Ghufron Mukti juga mengimbau pengelola rumah sakit tidak mengurangi jumlah tempat tidur perawatan pasien dalam upaya memenuhi kriteria KRIS. "Pesan saya jangan dikurangi akses dengan mengurangi jumlah tempat tidur. Pertahankan jumlah tempat tidur dan penuhi persyaratannya dengan 12 kriteria tersebut," tegas Ghufron.

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

2025-01-19 15:09:36So a while back i thought it might be fun to get a 3d printer and have a play with it, but when i saw that there was a whole element of making 3d files, it put me off.
recently, i was thinking, maybe it would be good to learn a new skill and then perhaps i could also sell 3d files, if i can get good enough.
but really, is it worth the time investment? or is 3d printing something i can enjoy without needing to be a 3d designer?
is it even a fun hobby?

2025-01-19 04:48:31A new report from the National Sports Shooting Foundation (NSSF) shows that civilian firearm possession exceeded 490 million in 2022. The total from 1990 to 2022 is estimated at 491.3 million firearms. In 2022, over ten million firearms were domestically produced, leading to a total of 16,045,911 firearms available in the U.S. market.
Of these, 9,873,136 were handguns, 4,195,192 were rifles, and 1,977,583 were shotguns. Handgun availability aligns with the concealed carry and self-defense market, as all states allow concealed carry, with 29 having constitutional carry laws.

2025-01-18 19:03:24Pain, in its multifaceted forms, often serves as a stark indicator of resistance within us. It's not just a physical or emotional signal that something is afoot; it's a profound reminder of our capacity to grow, adapt, and evolve.
While navigating life with an eye on innovation and personal development, pain can be seen through the lens of progress. Whether it's discomfort from pushing the boundaries of technology, or the personal challenge of aligning one's actions with deeper incentives, pain is often the precursor to significant growth.
Consider the journey of creating something truly useful, like an app that resonates with its users. This process is rarely smooth; it involves countless hours of debugging, rethinking, and overcoming the resistance of the mind to venture beyond the known. Each setback, each moment of frustration, is not merely an obstacle but a lesson in resilience, teaching us to refine our vision and strengthen our resolve.
Consider the people dearest to you. Our relationships are rarely smooth; each setback, each moment of frustration, is not merely an obstacle, but a lesson. The people closest to us are often the ones who can inflict the most pain, and vice versa. Perhaps the greatest pain of all is delivered by death when it steals our opportunity to rejoice in what we've learned with the ones that mattered most. Take heed of pain when it knocks on your door, the longer you resist, the greater the pain at a later date.
In this light, pain becomes a teacher. It teaches us that resistance, whether internal or external, is not a sign to retreat but to advance with wisdom. The growth we are destined for in our lives isn't handed to us; it's carved out of our responses to the pain we encounter. Every challenge, every moment of doubt, is a stepping stone towards a more robust version of ourselves.
Thus, embracing pain as an indicator of our resistance means acknowledging it as part of the journey towards personal mastery. It's a signal that we're pushing against our current limits, striving for something greater, something more aligned with our true potential. In this journey, pain doesn't just signify that we're resisting; it signifies that we're on the path to becoming who we are truly meant to be.

2024-04-22 22:20:47While I was in Mediera with all the other awesome people at the first SEC cohort there where a lot of discussions around data storage on nostr and if it could be made censorship-resistent
I remember lots of discussions about torrents, hypercore, nostr relays, and of course IPFS
There were a few things I learned from all these conversations:
- All the existing solutions have one thing in common. A universal ID of some kind for files
- HTTP is still good. we don't have to throw the baby out with the bath water
- nostr could fix this... somehow
Some of the existing solutions work well for large files, and all of them are decentralization in some way. However none of them seem capable of serving up cat pictures for social media clients. they all have something missing...
An Identity system
An identity system would allow files to be "owned" by users. and once files have owners servers could start grouping files into a single thing instead of a 1000+ loose files
This can also greatly simplify the question of "what is spam" for a server hosting (or seeding) these files. since it could simply have a whitelist of owners (and maybe their friends)
What is blossom?
Blossom is a set of HTTP endpoints that allow nostr users to store and retrieve binary data on public servers using the sha256 hash as a universal id
What are Blobs?
blobs are chunks of binary data. they are similar to files but with one key difference, they don't have names
Instead blobs have a sha256 hash (like
b1674191a88ec5cdd733e4240a81803105dc412d6c6708d53ab94fc248f4f553
) as an IDThese IDs are universal since they can be computed from the file itself using the sha256 hashing algorithm ( you can get a files sha256 hash on linux using:
sha256sum bitcoin.pdf
)How do the servers work?
Blossom servers expose four endpoints to let clients and users upload and manage blobs
GET /<sha256>
(optional file.ext
)PUT /upload
Authentication
: Signed nostr event- Returns a blob descriptor
GET /list/<pubkey>
- Returns an array of blob descriptors
Authentication
(optional): Signed nostr eventDELETE /<sha256>
Authentication
: Signed nostr event
What is Blossom Drive?
Blossom Drive is a nostr app built on top of blossom servers and allows users to create and manage folders of blobs
What are Drives
Drives are just nostr events (kind
30563
) that store a map of blobs and what filename they should have along with some extra metadataAn example drive event would be
json { "pubkey": "266815e0c9210dfa324c6cba3573b14bee49da4209a9456f9484e5106cd408a5", "created_at": 1710773987, "content": "", "kind": 30563, "tags": [ [ "name", "Emojis" ], [ "description", "nostr emojis" ], [ "d", "emojis" ], [ "r", "https://cdn.hzrd149.com/" ], [ "x", "303f018e613f29e3e43264529903b7c8c84debbd475f89368cb293ec23938981", "/noStrudel.png", "15161", "image/png" ], [ "x", "a0e2b39975c8da1702374b3eed6f4c6c7333e6ae0008dadafe93bd34bfb2ca78", "/satellite.png", "6853", "image/png" ], [ "x", "e8f3fae0f4a43a88eae235a8b79794d72e8f14b0e103a0fed1e073d8fb53d51f", "/amethyst.png", "20487", "image/png" ], [ "x", "70bd5836807b916d79e9c4e67e8b07e3e3b53f4acbb95c7521b11039a3c975c6", "/nos.png", "36521", "image/png" ], [ "x", "0fc304630279e0c5ab2da9c2769e3a3178c47b8609b447a30916244e89abbc52", "/primal.png", "29343", "image/png" ], [ "x", "9a03824a73d4af192d893329bbc04cd3798542ee87af15051aaf9376b74b25d4", "/coracle.png", "18300", "image/png" ], [ "x", "accdc0cdc048f4719bb5e1da4ff4c6ffc1a4dbb7cf3afbd19b86940c01111568", "/iris.png", "24070", "image/png" ], [ "x", "2e740f2514d6188e350d95cf4756bbf455d2f95e6a09bc64e94f5031bc4bba8f", "/damus.png", "32758", "image/png" ], [ "x", "2e019f08da0c75fb9c40d81947e511c8f0554763bffb6d23a7b9b8c9e8c84abb", "/old emojis/astral.png", "29365", "image/png" ], [ "x", "d97f842f2511ce0491fe0de208c6135b762f494a48da59926ce15acfdb6ac17e", "/other/rabbit.png", "19803", "image/png" ], [ "x", "72cb99b689b4cfe1a9fb6937f779f3f9c65094bf0e6ac72a8f8261efa96653f5", "/blossom.png", "4393", "image/png" ] ] }
There is a lot going on but the main thing is the list of "x" tags and the path that describes the folder and filename the blob should live at
If your interested, the full event definition is at github.com/hzrd149/blossom-drive
Getting started
Like every good nostr client it takes a small instruction manual in order to use it properly. so here are the steps for getting started
1. Open the app
Open https://blossom.hzrd149.com
2. Login using extension
You can also login using any of the following methods using the input - NIP-46 with your https://nsec.app or https://flare.pub account - a NIP-46 connection string - an
ncryptsec
password protected private key - ansec
unprotected private key (please don't) - bunker:// URI from nsecbunker3. Add a blossom server
Right now
https://cdn.satellite.earth
is the only public server that is compatible with blossom drive. If you want to host your own I've written a basic implementation in TypeScript github.com/hzrd149/blossom-server4. Start uploading your files
NOTE: All files upload to blossom drive are public by default. DO NOT upload private files
5. Manage files
Encrypted drives
There is also the option to encrypt drives using NIP-49 password encryption. although its not tested at all so don't trust it, verify
Whats next?
I don't know, but Im excited to see what everyone else on nostr builds with this. I'm only one developer at the end of the day and I can't think of everything
also all the images in this article are stored in one of my blossom drives here

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.

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.

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.
Not: Bu öykü ilk olarak 2020 yılında Esrarengiz Hikâyeler'de yayımlanmıştır.

2025-01-20 22:49:02Solomon, Moses, and Melchizedek were worshipping, and an enchanting beast was underneath the throne, and its mouth was an abyss. A cunning angel worshiped near the three prophets and said to them, "Any who can satisfy the Beast at the Lord's feet will be blessed forever." \ \ The three prophets spoke among themselves and asked the angel, "What is the beast's name?" \ \ And the angel answered them, "She is called ‘Desire’." \ \ Solomon went before the Beast and it spoke and said, "I can only be satisfied by great treasure." Solomon was a man of great riches, so he cast all his vast empire into the mouth of the Beast, but it was not filled. The Beast said, "What a marvelous offering! There are many great treasures, but something else is needed. You are blessed, but you shall go away empty-handed." Solomon was impoverished but rejoiced. \ \ Moses went before the Beast, and the Beast spoke and said, "Do you have great treasure?" Moses was a mighty prophet, so he struck the earth with his staff and made a river of gold flow into the mouth of the Beast for eternity, but it was not filled. The Beast spoke and said, "Moses, you are cursed to gaze until this river fills my belly." And Moses was cursed to gaze
upon the abyss that could not be filled until the end of the age. \ \ Melchizedek went before the Beast, and the Beast spoke and said, "No matter what I eat, I am not satisfied." Melchizedek said, "I see that if a man gives all he has, you are not satisfied. I see that if a man gives you treasures without meaning, it is the same as offering dust and you will curse him. Thus, I will give you a portion of a treasure that has great worth." Melchizedek had two jewels called Urim and Thummim. He gave the black stone to the Beast, and the Beast didn't desire to eat Urim without Thummim. She did not consume the jewel but gazed upon it and desired its pair. The Beast spoke and said, "Give me the other stone." Melchizedek replied, "If I give you the other, you will consume both and we will have nothing between us. Let us make a covenant; If you will not bless me or curse me, but let me live in peace, I will give you Thummim at the end of time." The Beast agreed to Melchizedek's request and fashioned Urim into an amulet, and that amulet became the only possession of the Beast called Desire. Thus, Melchizedek subdued Desire by teaching her that satisfaction is not in consumption, stockpiling, or might. Satisfaction is found in treasure shared between two souls.

2025-01-18 16:23:47My best ever was 197.5kg when I was at 95kg bodyweight.
Today (I've not trained DL in a little while), 180kg was rough, 182.5kg didn't even come off the ground :( I'm at 100kgs BW.
Not every day is a PR day. And letting your training lapse to go a different direction will result in a decline on the exercise you're not training.
Progress is slow. But i will breach 200kgs.
(NB, had a little popping sensation in my ribs during the 182.5 attempt, probably just a slight pull on an intercostal but now that's sore 😭😭)
Block by block, progressive overload 💪💪

Bold text work!
Images could have used nostr.build instead of raw S3 from us-east-1 region.
Very impressive! You can even save the draft and continue later, before posting the long-form note!

2025-01-18 14:47:34I sometimes find it amusing the thrill of the zap, how something like 500s makes me feel like I have won some kind of lottery. I won the fact of the day one time for 10k sats and I almost fell off my chair.
https://media.tenor.com/cdrOw1uwgpcAAAAC/borat-borat-king-in-the-castle.gif
In fiat terms, I shouldn't be getting excited about a few pence or dollars, but I think I know why. Because I only get sats from doing a bit of posting, I don't get loads and it changes the way I value them.
Now, of course, I earn in fiat and do a dca once a month into bitcoin, but since that goes straight to storage, it's abstracted away.
If I had a client that paid directly in sats or the world was on a btc standard, I also think it would be different. but when you can only get like 10 sats a day from fountain and a few a month on nostr, if that, the zaps here have a much bigger impact.
I also have a circular economy thing going on where before I didn't do anything with lightning, it was just this piece of tech, but not only has SN and nostr got me into using it, I also pay the kid's pocket money in sats that I earned just posting, I don't have to do any special buys for it. Just a little sat economy going on.
Do any of you also find it weirdly thrilling to get the equivalent of ten cents in zaps?

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.

2025-01-18 14:47:23Since I don't follow a particular regiment throughout the day, I need some guiding principles to stay on track. Previously, I wrote about Hormesis, which let's me be more comfortable being uncomfortable.
My primary weakness, when it comes to ~HealthAndFitness, is snacking. Honestly, "snacking" is putting it mildly. If there are unprotected baked goods in the house, I'm going to eat them until either they're gone or I'm too sick to continue.
The point where I am able to exercise some self-control is at the point of purchase. I have no problem (usually) keeping junk food out of my cart.
I will buy the ingredients to make baked goods, when my wife asks me to, though. However, being limited to homemade baked goods that other people make for me is a pretty good constraint. Plus, her cooking is healthier, tastier, and less expensive than prepackaged snacks.
I'm curious if this works for anyone else. Or, do you weirdos have self control when there are tasty treats in your vicinity?

2023-07-22 09:39:48Intro
This short tutorial will help you set up your own Nostr Wallet Connect (NWC) on your own LND Node that is not using Umbrel. If you are a user of Umbrel, you should use their version of NWC.
Requirements
You need to have a working installation of LND with established channels and connectivity to the internet. NWC in itself is fairly light and will not consume a lot of resources. You will also want to ensure that you have a working installation of Docker, since we will use a docker image to run NWC.
- Working installation of LND (and all of its required components)
- Docker (with Docker compose)
Installation
For the purpose of this tutorial, we will assume that you have your lnd/bitcoind running under user bitcoin with home directory /home/bitcoin. We will also assume that you already have a running installation of Docker (or docker.io).
Prepare and verify
git version - we will need git to get the latest version of NWC. docker version - should execute successfully and show the currently installed version of Docker. docker compose version - same as before, but the version will be different. ss -tupln | grep 10009- should produce the following output: tcp LISTEN 0 4096 0.0.0.0:10009 0.0.0.0: tcp LISTEN 0 4096 [::]:10009 [::]:**
For things to work correctly, your Docker should be version 20.10.0 or later. If you have an older version, consider installing a new one using instructions here: https://docs.docker.com/engine/install/
Create folders & download NWC
In the home directory of your LND/bitcoind user, create a new folder, e.g., "nwc" mkdir /home/bitcoin/nwc. Change to that directory cd /home/bitcoin/nwc and clone the NWC repository: git clone https://github.com/getAlby/nostr-wallet-connect.git
Creating the Docker image
In this step, we will create a Docker image that you will use to run NWC.
- Change directory to
nostr-wallet-connect
:cd nostr-wallet-connect
- Run command to build Docker image:
docker build -t nwc:$(date +'%Y%m%d%H%M') -t nwc:latest .
(there is a dot at the end) - The last line of the output (after a few minutes) should look like
=> => naming to docker.io/library/nwc:latest
nwc:latest
is the name of the Docker image with a tag which you should note for use later.
Creating docker-compose.yml and necessary data directories
- Let's create a directory that will hold your non-volatile data (DB):
mkdir data
- In
docker-compose.yml
file, there are fields that you want to replace (<> comments) and port “4321” that you want to make sure is open (check withss -tupln | grep 4321
which should return nothing). - Create
docker-compose.yml
file with the following content, and make sure to update fields that have <> comment:
version: "3.8" services: nwc: image: nwc:latest volumes: - ./data:/data - ~/.lnd:/lnd:ro ports: - "4321:8080" extra_hosts: - "localhost:host-gateway" environment: NOSTR_PRIVKEY: <use "openssl rand -hex 32" to generate a fresh key and place it inside ""> LN_BACKEND_TYPE: "LND" LND_ADDRESS: localhost:10009 LND_CERT_FILE: "/lnd/tls.cert" LND_MACAROON_FILE: "/lnd/data/chain/bitcoin/mainnet/admin.macaroon" DATABASE_URI: "/data/nostr-wallet-connect.db" COOKIE_SECRET: <use "openssl rand -hex 32" to generate fresh secret and place it inside ""> PORT: 8080 restart: always stop_grace_period: 1m
Starting and testing
Now that you have everything ready, it is time to start the container and test.
- While you are in the
nwc
directory (important), execute the following command and check the log output,docker compose up
- You should see container logs while it is starting, and it should not exit if everything went well.
- At this point, you should be able to go to
http://<ip of the host where nwc is running>:4321
and get to the interface of NWC - To stop the test run of NWC, simply press
Ctrl-C
, and it will shut the container down. - To start NWC permanently, you should execute
docker compose up -d
, “-d” tells Docker to detach from the session. - To check currently running NWC logs, execute
docker compose logs
to run it in tail mode add-f
to the end. - To stop the container, execute
docker compose down
That's all, just follow the instructions in the web interface to get started.
Updating
As with any software, you should expect fixes and updates that you would need to perform periodically. You could automate this, but it falls outside of the scope of this tutorial. Since we already have all of the necessary configuration in place, the update execution is fairly simple.
- Change directory to the clone of the git repository,
cd /home/bitcoin/nwc/nostr-wallet-connect
- Run command to build Docker image:
docker build -t nwc:$(date +'%Y%m%d%H%M') -t nwc:latest .
(there is a dot at the end) - Change directory back one level
cd ..
- Restart (stop and start) the docker compose config
docker compose down && docker compose up -d
- Done! Optionally you may want to check the logs:
docker compose logs

What I find striking here is the wording. No euphemisms, just straight up "almost constantly". Two aspects about this: 1. ofc you are lonely if you spend time alone "almost constantly". 2. The effect on our culture are unprecedentedly big. When was the last time in the last 2000 years that something oneshotted culture like this? I can't think of anything

2025-01-18 12:04:41Last Updated: January 18, 2025
First off, big shoutout to Coinos for having support for adding a memo to BOLT12 offers. This provides a solid alternative for the pleb who wants to support mining decentralization but doesn’t want to set up a CLN node and pay thousands of sats for a channel only to get little rewards. This is the case for most of us who only have a miner or two (e.g. a Bitaxe and/or an S9).
Before we get into setting up Lightning payouts, you’ll want to have your miner configured to mine with OCEAN of course. You’ll also want to make sure that the bitcoin address you use is from a wallet that supports signing messages.
These are the ones listed in the OCEAN docs:
- Bitcoin Knots/Bitcoin Core
- Coldcard
- Electrum
- LND (Command Line)
- Seedsigner
- Sparrow
- Specter
- Trezor
I checked one of my favorite, user-friendly wallets — Blue Wallet — and it happens to support signing messages as well.
Just tap the three dots on the upper right and you’ll see the “Sign/Verify Message” button at the bottom.
Update [January 18]: You can now use Coinos to sign by going to https://coinos.io/sign
The trick here is to not refresh the page. In other words, when you're logged in to your Coinos account, go to the URL and use the legacy address (starts with a "1") that's displayed to configure your miner(s). If you refresh the page, you're going to get a new address which will cause the signing to fail later on. Remember, keep the tab open and don't refresh the page.
Whichever wallet you choose, generate a receive address to use when configuring your miner (it’ll also be your OCEAN username).
Here’s how it looks on the Bitaxe (AxeOS)…
And the Antminer S9 (Braiins OS).
NOTE: There’s a slight difference in the URL format between the two apps. Other than that, the username will be your bitcoin address followed by the optional “.” + the nickname for your machine.
You can find more details on OCEAN’s get started page.
Alright, now that your miner is pointed at OCEAN. Let’s configure Lightning payouts!
Generating the BOLT12 Offer
In the Coinos app, go to Receive > Bolt 12.
Tap “Set memo” and set it to “OCEAN Payouts for [insert your bitcoin address]” (this text is case-sensitive). Use the same bitcoin address you used above to configure your miner(s).
After tapping OK, copy the BOLT12 offer (it should start with “lno”) and proceed to the next step.
Generating the Configuration Message
Navigate to the My Stats page by searching for your OCEAN Bitcoin address.
The click the Configuration link next to Next Block to access the configuration form.
Paste the BOLT12 offer here, update the block height to latest, click GENERATE, and copy the generated unsigned message.
Signing the Configuration Message
To sign the generated message, go back to Blue Wallet and use the signing function. Paste the configuration message in the Message field, tap Sign, and copy the signed message that’s generated.
If you're using Coinos to sign, return to the page that you kept open (and didn't refresh) and do the same. Paste the configuration message, click submit, and copy the signed message.
Submitting the Signed Message
Once signed, copy the signature, paste it in the OCEAN configuration form, and click CONFIRM.
If all goes well, you should see a confirmation that the configuration was successful. Congrats! 🎉
All you gotta do now is sit back, relax, and wait for a block to be found…
Or you can look into setting up DATUM. 😎

2023-04-11 19:36:53There’s a lot of conversation around the #TwitterFiles. Here’s my take, and thoughts on how to fix the issues identified.
I’ll start with the principles I’ve come to believe…based on everything I’ve learned and experienced through my past actions as a Twitter co-founder and lead:
- Social media must be resilient to corporate and government control.
- Only the original author may remove content they produce.
- Moderation is best implemented by algorithmic choice.
The Twitter when I led it and the Twitter of today do not meet any of these principles. This is my fault alone, as I completely gave up pushing for them when an activist entered our stock in 2020. I no longer had hope of achieving any of it as a public company with no defense mechanisms (lack of dual-class shares being a key one). I planned my exit at that moment knowing I was no longer right for the company.
The biggest mistake I made was continuing to invest in building tools for us to manage the public conversation, versus building tools for the people using Twitter to easily manage it for themselves. This burdened the company with too much power, and opened us to significant outside pressure (such as advertising budgets). I generally think companies have become far too powerful, and that became completely clear to me with our suspension of Trump’s account. As I’ve said before, we did the right thing for the public company business at the time, but the wrong thing for the internet and society. Much more about this here: https://twitter.com/jack/status/1349510769268850690
I continue to believe there was no ill intent or hidden agendas, and everyone acted according to the best information we had at the time. Of course mistakes were made. But if we had focused more on tools for the people using the service rather than tools for us, and moved much faster towards absolute transparency, we probably wouldn’t be in this situation of needing a fresh reset (which I am supportive of). Again, I own all of this and our actions, and all I can do is work to make it right.
Back to the principles. Of course governments want to shape and control the public conversation, and will use every method at their disposal to do so, including the media. And the power a corporation wields to do the same is only growing. It’s critical that the people have tools to resist this, and that those tools are ultimately owned by the people. Allowing a government or a few corporations to own the public conversation is a path towards centralized control.
I’m a strong believer that any content produced by someone for the internet should be permanent until the original author chooses to delete it. It should be always available and addressable. Content takedowns and suspensions should not be possible. Doing so complicates important context, learning, and enforcement of illegal activity. There are significant issues with this stance of course, but starting with this principle will allow for far better solutions than we have today. The internet is trending towards a world were storage is “free” and infinite, which places all the actual value on how to discover and see content.
Which brings me to the last principle: moderation. I don’t believe a centralized system can do content moderation globally. It can only be done through ranking and relevance algorithms, the more localized the better. But instead of a company or government building and controlling these solely, people should be able to build and choose from algorithms that best match their criteria, or not have to use any at all. A “follow” action should always deliver every bit of content from the corresponding account, and the algorithms should be able to comb through everything else through a relevance lens that an individual determines. There’s a default “G-rated” algorithm, and then there’s everything else one can imagine.
The only way I know of to truly live up to these 3 principles is a free and open protocol for social media, that is not owned by a single company or group of companies, and is resilient to corporate and government influence. The problem today is that we have companies who own both the protocol and discovery of content. Which ultimately puts one person in charge of what’s available and seen, or not. This is by definition a single point of failure, no matter how great the person, and over time will fracture the public conversation, and may lead to more control by governments and corporations around the world.
I believe many companies can build a phenomenal business off an open protocol. For proof, look at both the web and email. The biggest problem with these models however is that the discovery mechanisms are far too proprietary and fixed instead of open or extendable. Companies can build many profitable services that complement rather than lock down how we access this massive collection of conversation. There is no need to own or host it themselves.
Many of you won’t trust this solution just because it’s me stating it. I get it, but that’s exactly the point. Trusting any one individual with this comes with compromises, not to mention being way too heavy a burden for the individual. It has to be something akin to what bitcoin has shown to be possible. If you want proof of this, get out of the US and European bubble of the bitcoin price fluctuations and learn how real people are using it for censorship resistance in Africa and Central/South America.
I do still wish for Twitter, and every company, to become uncomfortably transparent in all their actions, and I wish I forced more of that years ago. I do believe absolute transparency builds trust. As for the files, I wish they were released Wikileaks-style, with many more eyes and interpretations to consider. And along with that, commitments of transparency for present and future actions. I’m hopeful all of this will happen. There’s nothing to hide…only a lot to learn from. The current attacks on my former colleagues could be dangerous and doesn’t solve anything. If you want to blame, direct it at me and my actions, or lack thereof.
As far as the free and open social media protocol goes, there are many competing projects: @bluesky is one with the AT Protocol, nostr another, Mastodon yet another, Matrix yet another…and there will be many more. One will have a chance at becoming a standard like HTTP or SMTP. This isn’t about a “decentralized Twitter.” This is a focused and urgent push for a foundational core technology standard to make social media a native part of the internet. I believe this is critical both to Twitter’s future, and the public conversation’s ability to truly serve the people, which helps hold governments and corporations accountable. And hopefully makes it all a lot more fun and informative again.
💸🛠️🌐 To accelerate open internet and protocol work, I’m going to open a new category of #startsmall grants: “open internet development.” It will start with a focus of giving cash and equity grants to engineering teams working on social media and private communication protocols, bitcoin, and a web-only mobile OS. I’ll make some grants next week, starting with $1mm/yr to Signal. Please let me know other great candidates for this money.

2025-01-18 08:07:09Obviously, bootstrapping your own LN node is hard, but it is also fun, because you get to understand how all the parts fit together, and it's what I do.
But some people prefer apps like Strike, Phoenix, and others which you can download on your phone and open all the channels for you. Maybe because they don't have the budget of many hundredK's of sats required to open enough channels to be well-connected. Or maybe because it's just easier.
The analogy perfectly fits with setting up your own software (or hardware) wallet instead of leaving your coins on an exchange. But that's quite an unsettling comparison because of how often exchanges fail. So at any rate, post in the replies your preference!

@ f9cf4e94:96abc355
2025-01-18 06:09:50Para esse exemplo iremos usar: | Nome | Imagem | Descrição | | --------------- | ------------------------------------------------------------ | ------------------------------------------------------------ | | Raspberry PI B+ |
| Cortex-A53 (ARMv8) 64-bit a 1.4GHz e 1 GB de SDRAM LPDDR2, | | Pen drive |
| 16Gb |
Recomendo que use o Ubuntu Server para essa instalação. Você pode baixar o Ubuntu para Raspberry Pi aqui. O passo a passo para a instalação do Ubuntu no Raspberry Pi está disponível aqui. Não instale um desktop (como xubuntu, lubuntu, xfce, etc.).
Passo 1: Atualizar o Sistema 🖥️
Primeiro, atualize seu sistema e instale o Tor:
bash apt update apt install tor
Passo 2: Criar o Arquivo de Serviço
nrs.service
🔧Crie o arquivo de serviço que vai gerenciar o servidor Nostr. Você pode fazer isso com o seguinte conteúdo:
```unit [Unit] Description=Nostr Relay Server Service After=network.target
[Service] Type=simple WorkingDirectory=/opt/nrs ExecStart=/opt/nrs/nrs-arm64 Restart=on-failure
[Install] WantedBy=multi-user.target ```
Passo 3: Baixar o Binário do Nostr 🚀
Baixe o binário mais recente do Nostr aqui no GitHub.
Passo 4: Criar as Pastas Necessárias 📂
Agora, crie as pastas para o aplicativo e o pendrive:
bash mkdir -p /opt/nrs /mnt/edriver
Passo 5: Listar os Dispositivos Conectados 🔌
Para saber qual dispositivo você vai usar, liste todos os dispositivos conectados:
bash lsblk
Passo 6: Formatando o Pendrive 💾
Escolha o pendrive correto (por exemplo,
/dev/sda
) e formate-o:bash mkfs.vfat /dev/sda
Passo 7: Montar o Pendrive 💻
Monte o pendrive na pasta
/mnt/edriver
:bash mount /dev/sda /mnt/edriver
Passo 8: Verificar UUID dos Dispositivos 📋
Para garantir que o sistema monte o pendrive automaticamente, liste os UUID dos dispositivos conectados:
bash blkid
Passo 9: Alterar o
fstab
para Montar o Pendrive Automáticamente 📝Abra o arquivo
/etc/fstab
e adicione uma linha para o pendrive, com o UUID que você obteve no passo anterior. A linha deve ficar assim:fstab UUID=9c9008f8-f852 /mnt/edriver vfat defaults 0 0
Passo 10: Copiar o Binário para a Pasta Correta 📥
Agora, copie o binário baixado para a pasta
/opt/nrs
:bash cp nrs-arm64 /opt/nrs
Passo 11: Criar o Arquivo de Configuração 🛠️
Crie o arquivo de configuração com o seguinte conteúdo e salve-o em
/opt/nrs/config.yaml
:yaml app_env: production info: name: Nostr Relay Server description: Nostr Relay Server pub_key: "" contact: "" url: http://localhost:3334 icon: https://external-content.duckduckgo.com/iu/?u= https://public.bnbstatic.com/image/cms/crawler/COINCU_NEWS/image-495-1024x569.png base_path: /mnt/edriver negentropy: true
Passo 12: Copiar o Serviço para o Diretório de Systemd ⚙️
Agora, copie o arquivo
nrs.service
para o diretório/etc/systemd/system/
:bash cp nrs.service /etc/systemd/system/
Recarregue os serviços e inicie o serviço
nrs
:bash systemctl daemon-reload systemctl enable --now nrs.service
Passo 13: Configurar o Tor 🌐
Abra o arquivo de configuração do Tor
/var/lib/tor/torrc
e adicione a seguinte linha:torrc HiddenServiceDir /var/lib/tor/nostr_server/ HiddenServicePort 80 127.0.0.1:3334
Passo 14: Habilitar e Iniciar o Tor 🧅
Agora, ative e inicie o serviço Tor:
bash systemctl enable --now tor.service
O Tor irá gerar um endereço
.onion
para o seu servidor Nostr. Você pode encontrá-lo no arquivo/var/lib/tor/nostr_server/hostname
.
Observações ⚠️
- Com essa configuração, os dados serão salvos no pendrive, enquanto o binário ficará no cartão SD do Raspberry Pi.
- O endereço
.onion
do seu servidor Nostr será algo como:ws://y3t5t5wgwjif<exemplo>h42zy7ih6iwbyd.onion
.
Agora, seu servidor Nostr deve estar configurado e funcionando com Tor! 🥳

2025-01-17 21:21:35This chocolate sauce recipe is easy to make at home. I hope you'll give this recipe a try.
Ingredients: + 1 liter of milk + 150-200 g of wholemeal flour + 20-100 g of chocolate + a fruit* of your choice (or a sweet potato). Skip it if your plan is to serve the sauce over fruits. + some salt
Directions:
Add a pinch of salt to the milk and set it to boil on low heat. In the meantime, mix the flour with pieces of chocolate and chunks of your chosen fruit. If using an orange, there's no need to chop it—simply separate the segments by hand along their natural divisions. Mixing the fruit and chocolate pieces with the flour ensures that they are coated, which helps prevent the flour from clumping.
Serving Suggestions: This sauce pairs well with bread, biscuits, or pancakes. Alternatively serve over lots of fruits (be they bananas, watermelons, apples) - in that case there is no need of mixing the chunks of fruits with the flour.

2025-01-17 19:40:21So nearly everybody in bitcoin hates ESG for all the obvious reasons. I'm not going to recap all that right now. That assumed, the E and S make a lot of sense on the personal level though, right? The problem is when they're used on an economic level. A __(fill in the blank industry) company's bottom line is in no way benefitted by shrinking their environmental footprint or being more socially equitable.
Well, did you see this block that @Catcher found this morning?!?!
One might be annoyed that his or her transaction was ignored (not sure censored is even the correct word here), but isn't this also really bad for MARA's bottom line? Are we starting to see a new type of ESG for a new political era? Maybe this example could be of the O for obsequious? We just need two more letters and we can start rating companies on a system that has nothing to do with them delivering a good product or service.
Either way, its time for us home miners to kick into overdrive! Yee-haw!

2025-01-17 17:25:20recently Joe Nakomoto was asking a similar question on nostr and most of the comments were ' add more value' and things like that. which is crazy, because the guy is literally traveling the world making bitcoin content (and doing an amazing job IMO).
but it seems like without the ads and sponsors we hate, most of the podcasts and youtube channels don't make enough to function. the idea of 'value harder' seems silly.
SN is the best example of V4V working IMO, but obviously to a small scale and as something fun on the side.
as for nostr, people say 'add more value', but as many have pointed out, the people that make all the zaps are simply known people saying GM, and even then, the zaps are relative peanuts compared to even SN
what do you guys think?

2025-01-17 17:23:25With the news of Facebook changing its policy on DEI I was reminded of how it started and my early thoughts on it. I don't think DEI is dead, far from it but there's a trend forming pushing back. With Facebook and companies in general you have to understand something. Companies are mostly spineless. If a company is pushing something its not "brave" or "risky". All companies are profit driven and when they run these "woke" commercial its not brave. It would have been brave for companies to speak boldly against racism in the 50s but not today. Today most people oppose racism. Not saying we are rid of racism but just that companies are like a flag flying in the wind. They show you the direction the winds are blowing in culture and politics.
I have to say the whole DEI story line has been interesting to watch over the past 20 years. 20 years? Yeah that's what I said because its been a long arc. 20 years is probably to short but in the tech field I'd argue it really started back in the mid 2000s.
In the early 2000s I remember a push to make the tech field more friendly to women. To rid the startup culture of the bro culture and make it more welcoming and less like a college fraternity culture. I had no problem with any of that. But it became clear that very vocal people were not satisfied with that. It wasn't enough to not discriminate and stop tolerating sexism. We needed to actively set quotas for female speakers at conferences and have more diverse representation all over the place. The idea of meritocracy which was once the hallmark of the high tech industry was denigrated.
In the place of meritocracy we have what some have called "positive discrimination". At least that is the perception of critics of DEI. It can be easy to ignore your critics and sometimes that is a good approach. But when your goals are changing the hearts and minds, which at least in the early days of DEI seemed to be the goal, it is vital. Before I offer criticism of DEI I want to say a few positive things about it. From my perspective working in tech for 20 years I think it is good that the culture has become more vocal about "isms". Racism and sexism will always be with us but we should strive to treat people fairly. I've seen both of these in my work life and people are much more comfortable speaking up than they were in the past. That's not a bad thing.
To me it is obvious that quotas and pushing lies like the wage gap harmed the goals of DEI. Why do I say this? Stay with me here. If you believe there are people that just hate women or are racists in an industry those people are very unlikely to come over to your side. So you of course have people that agree with your DEI agenda but to me the focus of DEI is really the middle. Those that aren't sexist or racist but also aren't that motivated. The majority of workers in the early 2000s at least were white males. I believe this is still true today. For the last 20 years this group have been ridiculed on mass and told they are the problem. If this is the group you are seeking to win over... I can't think of a more terrible strategy. So either you have people who just think they are terrible and are being told there isn't much if anything they can do about their racism and sexism. Or you have people who buck up against how they are being lumped in with real racists and sexists.
You end up making enemies of allies. I have watched this happen in the industry over the years. As DEI has expanded into other industries this push back has only became stronger.
Another unintended consequence of DEI seems obvious to me but I rarely hear it mentioned. Today when you see something go wrong and the org has been vocal about DEI those that DEI claims to protect become the obvious targets. This is regardless of any evidence. It just seems like if you are saying we hire and promote on a basis other than merit or qualifications you are not hiring the best. That doesn't mean someone that is a minority isn't as good as a white male but when you discriminate you undercut those you claim to protect.
The loudest voices in DEI have done a terrible job. They have made enemies of allies. When you aren't honest about statistics and data, when you lump people into massive groups and boil everything down to biology and DNA you show your true colors. People don't buy it. I believe this is what we are seeing with the rejection of DEI. When you build something on lies and half truths it is doomed to fail. I'm convinced MOST people that support DEI are just good hearted people that have been manipulated and propagandized. DEI on the surface sounds good to most people. Those that respond in hate to DEI also provide a good boogie man. Divide and conquer works for a while but in the end truth wins.
What do you think?

2025-01-17 17:01:07About 6 years ago I took the hard decision to leave WhatsApp as I begun my privacy journey, it was a hard decision as they have a huge exit barrier (e.g. not having an easy way to take your conversations with you, even if you can't import it somewhere else) and also very strong network effect.
It has been an interesting experience as people don't seem to understand or accept the fact I'm not a WhatsApp user, they ask me to abandon my decision and go back. I believe they are doing it because it's a lot more convenient to have all their contacts and conversations in a single app, and people doesn't seem concerned about their privacy (AFAIK it was never proven WhatsApp has backdoors, their walled garden won't allow us to audit).
Recently in Joe Rogan's interview with Mark Zuckeberg, and they talked about encryption at the very end of the episode, he still claims they share a lot of technology with Signal (no shit Sherlock, you literally took the code into your walled garden) and the only way for someone to access your conversations is if they gain access to the device itself (govts using pegasus with various zero day exploits).
I'm still trying to find the best option without shitcoiners behind it, I did find this spreadsheet with many messaging apps and various criteria, but haven't decided on something I like more than Signal. Did you?
--
EDIT: As a founder I admire that everybody seem to love WhatsApp UX and feature set, and on top of that they have the exit barrier and the network effect. I wonder what will take for people to change to something else.

We're in the home stretch of Futbol Americano season. The College Football championship game on Monday will be the final round of our College Football Playoff Pool. However, the NFL Playoffs are also the opening rounds of the Team USA!!! vs "the world" challenge.
As a slight aside, I'm very much looking forward to these markets closing on Predyx, so I can get some of my sats back.
We'll also talk about where various coaches will end up in the NFL.
NBA
The Celtics are looking a bit more mortal. Is that real or just a January lull?
KAT Corner
Loser of the Week (submit your entries)
MLB
Offseason news
I think @grayruby wants to apply the Ewing Theory to Juan Soto, but we'll have to find out.
NHL
Ovi watch
Other Territory News
UEFA and Cricket contest updates
What else should we cover?
My Game of the Week nominee is actually from last week. Is that allowed? There weren't many great games this week.

2025-01-17 14:05:02If I'm looking at this graph right, then the total zaps per month are somewhere around 100-110k sats. At the same time, the monthly fee for territory is 50k sats.
So we have 20+ territories, all sharing the total income of 100k, while spending 50k per month each? Or what am I missing?

@ 74718b83:b8204bd8
2025-01-17 11:44:14In the past I have worked on the Amazon accounts of some very big collagen brands and I have to say, there is almost no reason at all for anyone to be taking collagen instead of any other source of protein, like whey.
Somehow (probably tiktok), over the years, collagen has become a super popular supplement for women, mainly for perceived nail, hair, and skin health benefits etc.
But here's the thing, if you consume collagen directly, it doesn't magically then get sent to hair, nails or other body parts. It is cleaved into amino acids and re-synthesised by your body into collagen and used where needed.
The key thing is just getting enough protein overall.
Now, if you have a protein-deficient diet (which many women do), yes there might be some benefit, but it will be less benefit than just taking a protein shake (or just eating more chicken or other protein sources).
Why whey?
Because whey protein has a complete amino acid profile, higher bioavailability, and is better at stimulating protein synthesis (higher amino acid levels also mean whey produces more keratin, which is mainly what hair and nails are composed of).
Not only that, whey is a lot cheaper. Here's a quick price and ingredient breakdown I did on a popular collagen brand V ON whey
As you can see, you get almost TRIPPLE the amount of grams, at 10 pounds cheaper (that's over 12 US cuck bucks) and you're missing out on the BCAAs too.
So you are paying a lot more, getting a hell of a lot less, and the benefits will be no better. Even when collagen supplements add in an amino blend, it still ends up being more expensive.
But there must be some benefit to collagen, right?
So one of the touted benefits is it's good for joints and this is because it has more glycine, proline, and hydroxyproline that are needed for the synthesis of connective tissues (skin, tendons, and cartilage).
So why this might be an option, it's so expensive, I would still say just use whey and add in a joint support supplement separately and it will come out cheaper (or eat bone broth, organ meats, cartilage etc).
And yes, you can get all this from real food, I'm just pointing this out because it boggles my mind seeing the sales numbers for something that is basically just an inferior and more expensive version of a protein shake.

@ 000002de:c05780a7
2025-01-16 18:20:29The more I learn about these terrible fires in LA the more damning the case against government becomes. Granted, I think the monopoly of the "state" is evil for many reasons but still.
The idea that this disaster can be laid at any other individual or group's feet is absurd. Isn't it? Every aspect of this to me seems to be owned or largely influenced by the various levels of government. Its kinda mind blowing to me.
I bet, if we had a free society and the cities were privately managed by different companies, if you had insurance companies that hired fire prevention services and those companies were found to be as incompetent as the various government agencies there would be massive lawsuits filed. Companies would go bankrupt. The insurance companies would be blamed without hesitation.
All of this would be justified. This mind virus of "government" being special because it isn't private is really being shown to be absurd. Political incentives are being shown to be inferior to market incentives over and over again. The people are taught to believe this nonsense by the government schools populated by teachers that believe the same nonsense.
How does it end? This tragedy makes me wonder. California's government is not special. Its just closer to socialism than other states. When you read about the USSR you find there were many failures and absurd ones. We are seeing just a small taste of this in California. California is not alone. We see government failures in New Orleans and in the floods of North Carolina as well.
I hope more people begin to see what is going on but I'm not counting on it.

@ 000002de:c05780a7
2025-01-16 00:15:54I have had the same network setup for a long time now. Unifi stuff just works most of the time. I didn't really pick it. Its not open source and now that I have fiber and have been having some issues with some of the Unifi hardware its time to make the call.
Do I just upgrade with Unifi or start migrating to something more in line with what I value.
So I've been chatting with my very helpful colleges at Red Hat and after mentioning PfSense to them I was told to check out Opnsense instead.
- I want to slowly move to 10g network gear
- I need PoE switches that are 10g
- I want a robust firewall / router
- I don't really wanna build my router due to time
Currently looking at Protectli Buyer’s Guide who sell hardware that is pre-installed with many options. I haven't decided which one to get yet. I wanna buy with the future in mind though so 10g connections are a must and support for two WAN connection is as well. I'm glad I ran CAT6 in my house years ago instead of cheaping out.
After I replace my router / firewall I will want to replace my Unifi switches. I'm considering buying used Cisco switches from eBay.
Anyone have any advice on this plan or advice?

@ 50809a53:e091f164
2025-01-20 22:30:01For starters, anyone who is interested in curating and managing "notes, lists, bookmarks, kind-1 events, or other stuff" should watch this video:
https://youtu.be/XRpHIa-2XCE
Now, assuming you have watched it, I will proceed assuming you are aware of many of the applications that exist for a very similar purpose. I'll break them down further, following a similar trajectory in order of how I came across them, and a bit about my own path on this journey.
We'll start way back in the early 2000s, before Bitcoin existed. We had https://zim-wiki.org/
It is tried and true, and to this day stands to present an option for people looking for a very simple solution to a potentially complex problem. Zim-Wiki works. But it is limited.
Let's step into the realm of proprietary. Obsidian, Joplin, and LogSeq. The first two are entirely cloud-operative applications, with more of a focus on the true benefit of being a paid service. I will assume anyone reading this is capable of exploring the marketing of these applications, or trying their freemium product, to get a feeling for what they are capable of.
I bring up Obsidian because it is very crucial to understand the market placement of publication. We know social media handles the 'hosting' problem of publishing notes "and other stuff" by harvesting data and making deals with advertisers. But- what Obsidian has evolved to offer is a full service known as 'publish'. This means users can stay in the proprietary pipeline, "from thought to web." all for $8/mo.
See: https://obsidian.md/publish
THIS IS NOSTR'S PRIMARY COMPETITION. WE ARE HERE TO DISRUPT THIS MARKET, WITH NOTES AND OTHER STUFF. WITH RELAYS. WITH THE PROTOCOL.
Now, on to Joplin. I have never used this, because I opted to study the FOSS market and stayed free of any reliance on a paid solution. Many people like Joplin, and I gather the reason is because it has allowed itself to be flexible and good options that integrate with Joplin seems to provide good solutions for users who need that functionality. I see Nostr users recommending Joplin, so I felt it was worthwhile to mention as a case-study option. I myself need to investigate it more, but have found comfort in other solutions.
LogSeq - This is my "other solutions." It seems to be trapped in its proprietary web of funding and constraint. I use it because it turns my desktop into a power-house of note archival. But by using it- I AM TRAPPED TOO. This means LogSeq is by no means a working solution for Nostr users who want a long-term archival option.
But the trap is not a cage. It's merely a box. My notes can be exported to other applications with graphing and node-based information structure. Specifically, I can export these notes to:
- Text
- OPML
- HTML
- and, PNG, for whatever that is worth.
Let's try out the PNG option, just for fun. Here's an exported PNG of my "Games on Nostr" list, which has long been abandoned. I once decided to poll some CornyChat users to see what games they enjoyed- and I documented them in a LogSeq page for my own future reference. You can see it here:
https://i.postimg.cc/qMBPDTwr/image.png
This is a very simple example of how a single "page" or "list" in LogSeq can be multipurpose. It is a small list, with multiple "features" or variables at play. First, I have listed out a variety of complex games that might make sense with "multiplayer" identification that relies on our npubs or nip-05 addresses to aggregate user data. We can ALL imagine playing games like Tetris, Snake, or Catan together with our Nostr identities. But of course we are a long way from breaking into the video game market.
On a mostly irrelevant sidenote- you might notice in my example list, that I seem to be excited about a game called Dot.Hack. I discovered this small game on Itch.io and reached out to the developer on Twitter, in an attempt to purple-pill him, but moreso to inquire about his game. Unfortunately there was no response, even without mention of Nostr. Nonetheless, we pioneer on. You can try the game here: https://propuke.itch.io/planethack
So instead let's focus on the structure of "one working list." The middle section of this list is where I polled users, and simply listed out their suggestions. Of course we discussed these before I documented, so it is note a direct result of a poll, but actually a working interaction of poll results! This is crucial because it separates my list from the aggregated data, and implies its relevance/importance.
The final section of this ONE list- is the beginnings of where I conceptually connect nostr with video game functionality. You can look at this as the beginning of a new graph, which would be "Video Game Operability With Nostr".
These three sections make up one concept within my brain. It exists in other users' brains too- but of course they are not as committed to the concept as myself- the one managing the communal discussion.
With LogSeq- I can grow and expand these lists. These lists can become graphs. Those graphs can become entire catalogues of information than can be shared across the web.
I can replicate this system with bookmarks, ideas, application design, shopping lists, LLM prompting, video/music playlists, friend lists, RELAY lists, the LIST goes ON forever!
So where does that lead us? I think it leads us to kind-1 events. We don't have much in the way of "kind-1 event managers" because most developers would agree that "storing kind-1 events locally" is.. at the very least, not so important. But it could be! If only a superapp existed that could interface seamlessly with nostr, yada yada.. we've heard it all before. We aren't getting a superapp before we have microapps. Basically this means frameworking the protocol before worrying about the all-in-one solution.
So this article will step away from the deep desire for a Nostr-enabled, Rust-built, FOSS, non-commercialized FREEDOM APP, that will exist one day, we hope.
Instead, we will focus on simple attempts of the past. I encourage others to chime in with their experience.
Zim-Wiki is foundational. The user constructs pages, and can then develop them into books.
LogSeq has the right idea- but is constrained in too many ways to prove to be a working solution at this time. However, it is very much worth experimenting with, and investigating, and modelling ourselves after.
https://workflowy.com/ is next on our list. This is great for users who think LogSeq is too complex. They "just want simple notes." Get a taste with WorkFlowy. You will understand why LogSeq is powerful if you see value in WF.
I am writing this article in favor of a redesign of LogSeq to be compatible with Nostr. I have been drafting the idea since before Nostr existed- and with Nostr I truly believe it will be possible. So, I will stop to thank everyone who has made Nostr what it is today. I wouldn't be publishing this without you!
One app I need to investigate more is Zettlr. I will mention it here for others to either discuss or investigate, as it is also mentioned some in the video I opened with. https://www.zettlr.com/
On my path to finding Nostr, before its inception, was a service called Deta.Space. This was an interesting project, not entirely unique or original, but completely fresh and very beginner-friendly. DETA WAS AN AWESOME CLOUD OS. And we could still design a form of Nostr ecosystem that is managed in this way. But, what we have now is excellent, and going forward I only see "additional" or supplemental.
Along the timeline, Deta sunsetted their Space service and launched https://deta.surf/
You might notice they advertise that "This is the future of bookmarks."
I have to wonder if perhaps I got through to them that bookmarking was what their ecosystem could empower. While I have not tried Surf, it looks interested, but does not seem to address what I found most valuable about Deta.Space: https://webcrate.app/
WebCrate was an early bookmarking client for Deta.Space which was likely their most popular application. What was amazing about WebCrate was that it delivered "simple bookmarking." At one point I decided to migrate my bookmarks from other apps, like Pocket and WorkFlowy, into WebCrate.
This ended up being an awful decision, because WebCrate is no longer being developed. However, to much credit of Deta.Space, my WebCrate instance is still running and completely functional. I have since migrated what I deem important into a local LogSeq graph, so my bookmarks are safe. But, the development of WebCrate is note.
WebCrate did not provide a working directory of crates. All creates were contained within a single-level directory. Essentially there were no layers. Just collections of links. This isn't enough for any user to effectively manage their catalogue of notes. With some pressure, I did encourage the German developer to flesh out a form of tagging, which did alleviate the problem to some extent. But as we see with Surf, they have pioneered in another direction.
That brings us back to Nostr. Where can we look for the best solution? There simply isn't one yet. But, we can look at some other options for inspiration.
HedgeDoc: https://hedgedoc.org/
I am eager for someone to fork HedgeDoc and employ Nostr sign-in. This is a small step toward managing information together within the Nostr ecosystem. I will attempt this myself eventually, if no one else does, but I am prioritizing my development in this way:
- A nostr client that allows the cataloguing and management of relays locally.
- A LogSeq alternative with Nostr interoperability.
- HedgeDoc + Nostr is #3 on my list, despite being the easiest option.
Check out HedgeDoc 2.0 if you have any interest in a cooperative Markdown experience on Nostr: https://docs.hedgedoc.dev/
Now, this article should catch up all of my dearest followers, and idols, to where I stand with "bookmarking, note-taking, list-making, kind-1 event management, frameworking, and so on..."
Where it leads us to, is what's possible. Let's take a look at what's possible, once we forego ALL OF THE PROPRIETARY WEB'S BEST OPTIONS:

Nostr is even inspired by much of the history that has gone into information management systems. nostr:npub1jlrs53pkdfjnts29kveljul2sm0actt6n8dxrrzqcersttvcuv3qdjynqn I know looks up to Gordon Brander, just as I do. You can read his articles here: https://substack.com/@gordonbrander and they are very much worth reading! Also, I could note that the original version of Highlighter by nostr:npub1l2vyh47mk2p0qlsku7hg0vn29faehy9hy34ygaclpn66ukqp3afqutajft was also inspired partially by WorkFlowy.
About a year ago, I was mesmerized coming across SubText and thinking I had finally found the answer Nostr might even be looking for. But, for now I will just suggest that others read the Readme.md on the SubText Gtihub, as well as articles by Brander.
Good luck everyone. I am here to work with ANYONE who is interested in these type of solution on Nostr.
My first order of business in this space is to spearhead a community of npubs who share this goal. Everyone who is interested in note-taking or list-making or bookmarking is welcome to join. I have created an INVITE-ONLY relay for this very purpose, and anyone is welcome to reach out if they wish to be added to the whitelist. It should be freely readable in the near future, if it is not already, but for now will remain a closed-to-post community to preemptively mitigate attack or spam. Please reach out to me if you wish to join the relay. https://logstr.mycelium.social/
With this article, I hope people will investigate and explore the options available. We have lots of ground to cover, but all of the right resources and manpower to do so. Godspeed, Nostr.
