Accept Bitcoin in Three Minutes

Setting up Bitcoin payments has long been a challenge for merchants, requiring technical expertise, third-party processors, and lengthy verification procedures. Flash 2.0 eliminates these barriers, allowing any business to start accepting Bitcoin in just three minutes, with no technical set-up and full control over their funds.

The Bitcoin Payment Revolution

The world is witnessing a seismic shift in finance. Governments are backing Bitcoin funds, major companies are adding Bitcoin to their balance sheets, and political figures are embracing it as the future of money. Just as Stripe revolutionized internet payments, Flash is now doing the same for Bitcoin. Businesses that adapt today will gain a competitive edge in a rapidly evolving financial landscape.

With Bitcoin adoption accelerating, consumers are looking for places to spend it. Flash 2.0 ensures businesses of all sizes can seamlessly accept Bitcoin and position themselves at the forefront of this financial revolution.

All-in-One Monetization Platform

More than just a payment gateway, Flash 2.0 is a complete Bitcoin monetization suite, providing multiple ways for businesses to integrate Bitcoin into their operations. Merchants can accept payments online and in-store, content creators can monetize with donations and paywalls, and freelancers can send instant invoices via payment links.

For example, a jewelry designer selling products on WooCommerce can now integrate Flash for online payments, use Flash’s Point-of-Sale system at trade shows, enable Bitcoin donations for her digital artwork, and lock premium content behind Flash Paywalls. The possibilities are endless.

E-Commerce for Everyone

With built-in integrations for Shopify, WooCommerce, and soon Wix and OpenCart, Flash 2.0 enables Bitcoin payments on 95% of e-commerce stores worldwide. Businesses can now add Bitcoin as a payment option in just a few clicks—without needing developers or external payment processors.

And for those looking to start selling, Flash’s built-in e-commerce features allow users to create online stores, showcase products, and manage payments seamlessly.

No Middlemen, No Chargebacks, No Limits

Unlike traditional payment platforms, Flash does not hold or process funds. Businesses receive Bitcoin directly, instantly, and securely. There are no chargebacks, giving merchants full control over refunds and eliminating fraud. Flash also remains KYC-free, ensuring a seamless experience for businesses and customers alike.

A Completely Redesigned Experience

“The world is waking up to Bitcoin. Just like the internet revolutionized commerce, Bitcoin is reshaping finance. Businesses need solutions that are simple, efficient, and truly decentralized. Flash 2.0 is more than just a payment processor—it’s a gateway to the future of digital transactions, putting financial power back into the hands of businesses.”

— Pierre Corbin, CEO at Flash.

Flash 2.0 introduces a brand-new user interface, making it easier than ever to navigate, set up payments, and manage transactions. With an intuitive dashboard, streamlined checkout, and enhanced mobile compatibility, the platform is built for both new and experienced Bitcoin users.

Saturday 9AM It’s a chilly Saturday morning in Warsaw, and I don’t want to get out of bed. This is not because of the hangover; it’s because I feel like a failure.

The first day of Bitcoin FilmFest was a whirlwind of workshops, panels and running between stages. The pitch competition did not go my way. Another ‘pitching rabbit’ (an actual experienced film-maker) was selected to win the €3,000 of funding.

Rather than get up and search for coffee, I replay the scenes in my head. What could I have done differently? Will investors ever believe in me: I’m just a writer with no contacts in the industry. Do I have what it takes to produce a film?

Eventually, I haul myself out of bed and walk to Amondo, the festival’s morning HQ (and technically, the smallest cinema in Europe). Upon arrival, I find Bitcoin psychonaut Ioni Appelberg holding court in front of around a dozen enraptured disciples. Soon, the conversation spills out to the street to free up space for more workshops.

I attend a talk on film funding, then pay for coffee using bitcoin. I see familiar faces from the two previous nights. We compare notes on Friday night and check the day’s schedule. The morning clouds burn off, and things feel a little brighter.

The afternoon session begins just a few blocks away in the towering Palace of Culture and Science. My role in today's proceedings is to present my freedom fiction project, 21 Futures, on the community stage. Other presentations range from rap videos and advice on finding jobs in bitcoin to hosting ‘Bitcoin Walks’. This is how we are fixing the culture.

Saturday 8PM I feel a tap on my shoulder. ‘Excuse me, Mr. Philip. Your car is waiting. The Producers’ Dinner is starting soon’.

What? Me, a producer? I’ve been taking part in some panels and talks, but I assumed my benefits as a guest were limited to a comped ticket and generous goodie bag.

Soon, I am sharing a taxi with a Dubai-based journalist, a Colombian director, and the cypherpunk sponsor of the pitch competition I didn’t win.

The pierogies I dreamed of earlier that day somehow manifest (happy endings do exist), and we enjoy a raucous dinner including obligatory slivovitz.

Sunday 2AM The last few hours of blur include a bracing city-bike ride in a crew of nine attendees back to the Palace of Culture, chatting with a fellow bitcoin meetup organiser, and vaguely promising to attend a weekend rave with a crew of Polish artists and musicians on the outskirts of London.

I leave the party while it’s still in full swing. In five hours, I have to wake up to complete my Run for Hal in Marshal Edward Rydz-Śmigły Park.

---

Thursday 9PM The festival kicks off in Samo Centrum on Pizza Day. I arrive in a taxi straight from a cramped flight (fix the airlines!), having not eaten for around ten hours.

The infectious sounds of softly spoken Aussie bitrocker Roger9000 pound into the damp night. I’m three beers in, being presented by the organisers to attendees like a (very tall) show pony. I try to explain more about my books, my publishing connections, my short film.

When I search for the food I ordered an hour ago, I find it has been given away. The stern-faced Polish pizza maker shrugs. ‘You not here.’

I’m so hungry I could cry (six hours of Ryanair can do that to a man). And then, a heroic Czech pleb donates half a pizza to me. Side note: this same heroic pleb accidentally locked me out of my film-funds while trying to fix a wallet bug on Sunday night.

I step out into the rain. Roger9000 reminds us we should have laser eyes well past 100k. I take a bite of pizza and life tastes good.

---

The Films Side events, artists, late nights, and pitcher’s regret is all well and good, but what of the films?

My highlights included Golden Rabbit winner No More Inflation — a moving narrative with interviews from two dozen economists, visionaries, and inflation survivors.

Hotel Bitcoin, was a surprisingly funny comedy romp about a group of idiots who happen across a valuable laptop.

Revolución Bitcoin — an approachable and thorough documentary aimed to bring greater adoption in the Spanish-speaking world.

And, as a short-fiction guy, I enjoyed the short films The Man Who Wouldn’t Cry, a visit to New York’s only Somali restaurant in Finding Home.

---

Sunday 7PM The award ceremony has just finished. I head to Amondo for the final time to pay for mojitos in bitcoin and say goodbye to newly made friends. I feel like I’ve met almost everyone in attendance. Are you going to BTC Prague?!? we ask as we part ways.

Of course, the best thing about any festival is the people, and BFF25 had a cast of characters worthy of any art house flick:

• The bright-eyed and confident frontwoman of the metal band Scardust
• A nostr-native artist selling his intricate canvases to the highest zapper
• A dreadlocked DJ who wears a pair of flying goggles on his head at all times
• An affable British filmmaker explaining the virtues of the word ‘chucklesome’
• A Duracell-powered organiser who seems to know every song, person, film, book, and guest at the festival.

Warsaw itself feels like it has a role to play, too. Birdsong and green parks contrast the foreboding Communist-era architecture. The weather changes faster than my mood — heavy greys transform to bright sunshine. The roads around the venue close on Sunday for a political rally. And there we are in the middle, watching our bitcoin films.

Tuesday 10AM I’m at home now, squinting at my email inbox and piles of washing, wondering when the hell I’ll find time. The festival Telegram group is still buzzing with activity. Side events like martial arts tutorials, trips to a shooting range, boat tours. 5AM photos of street graffiti, lost and found items, and people asking ‘is anyone still around?’

This was not just a film festival. BFF is truly a celebration of culture — Art. Books. Comedy. Music. Video. Talk. Connection.

All this pure signal has lifted my spirits so much that despite me being a newbie filmmaker, armed only with a biro, a couple of powerpoints and a Geyser fund page, I know I will succeed in my mission. It turns out you can just film things.

You may have attended bitcoin conferences before — you know, the ones with ‘fireside chats’, VIP areas, and overpriced merch. Bitcoin FilmFest is a moment in time. We are fixing the culture, year after year, until art can flourish again.

As fellow author Aaron Koenig commented during a panel session, ‘In twenty years, we won’t be drawing laser eyes and singing about honey badgers. Our grandchildren won’t understand the change we went through.’

Would I do it all again? Of course!

Join me next June in Warsaw.
I’ll be the tall one presenting his short animation premiere.

COD (chemical oxygen demand) sensors play a vital role in water quality testing. Their main functions include real-time monitoring, pollution event warning, water quality assessment and pollution source tracking. The following are the specific roles and applications of COD sensors in water quality testing:

Real-time monitoring and data acquisition COD sensors can monitor the COD content in water bodies in real time and continuously. Compared with traditional sampling methods, COD sensors are fast and accurate, without manual sampling and laboratory testing, which greatly saves time and labor costs. By combining with the data acquisition system, the monitoring data can be uploaded to the cloud in real time to form a extemporization distribution map of the COD content in the water body, providing detailed data support for environmental monitoring and management.

Pollution event warning and rapid response COD sensors play an important role in early warning and rapid response in water environment monitoring. Once there is an abnormal increase in organic matter in the water body, the COD sensor can quickly detect the change in COD content and alarm through the preset threshold. This enables relevant departments to take measures at the early stage of the pollution incident to prevent the spread of pollution and protect the water environment.

Water quality assessment and pollution source tracking COD sensors play an important role in water quality assessment and pollution source tracking. By continuously monitoring the COD content in water bodies, the water quality can be evaluated and compared with national and regional water quality standards. At the same time, COD sensors can also help determine and track the location and spread of pollution sources, provide accurate data support for environmental management departments, and guide the development of pollution prevention and control work.

Application scenarios COD sensors are widely used in various water quality monitoring scenarios, including but not limited to: Sewage treatment plants: used to monitor the COD content of in fluent and effluent to ensure the effect of sewage treatment. Water source protection and management: deployed in water sources to monitor the COD content of in fluent sources. Once the water quality exceeds the set limit, the system will issue an alarm in time to ensure water quality safety. Lake and river monitoring: deployed in water bodies such as lakes and rivers to monitor the COD content of water bodies in real time.

Technical features of COD sensor COD sensor uses advanced technology, such as ultraviolet absorption method, which does not require the use of chemical reagents, avoiding the risk of contamination of chemical reagents in traditional COD detection methods, and can achieve online uninterrupted water quality monitoring, providing strong support for real-time water quality assessment. In addition, COD sensor also has the advantages of low cost, high stability, strong anti-interference ability, and convenient installation.

Summary In summary, COD sensor plays an irreplaceable role in water quality detection. It can not only provide real-time and accurate water quality data, but also quickly warn when pollution incidents occur, providing strong technical support for water quality management and environmental protection. With the advancement of technology and the popularization of applications, COD sensor will play a more important role in water quality monitoring in the future.

3. Uloga Vlade u Cantillonovom Efektu
4. Zaštitite Sebe od Cantillonovog Efekta
5. Kako mogu da saznam više o Bitcoin-u?

Pitanje o tome zašto nam je potreban Bitcoin danas je postalo veoma uobičajeno, ali odgovori obično ostavljaju većinu ljudi zbunjenim i sa izjavama da je on, ili Ponzijeva šema ili novac za kriminalce. Ovaj zaključak nije pravičan prema načinu na koji bi Bitcoin mogao da transformiše sistemsku nepravednost i korupciju koja je usadjena u naš trenutni monetarni sistem. Jedna od ovih nejednakosti u našem današnjem sistemu rezultat je Cantillonovog Efekta, davno zaboravljene klasične teorije o tome kako raspodela novca utiče na bogatstvo pojedinca.

Cantillonov Efekat opisuje kako stvaranje novog novca donosi korist onima koji prvi dobiju novac, a na štetu onih koji su najudaljeniji od stvaranja novog novca. U današnjem monetarnom sistemu banke i korporacije su najbliže novom novcu dok je srednja klasa najudaljenija. Bitcoin to ispravlja, davanjem novih bitcoin-a samo „rudarima“ koji osiguravaju protokol – mnogo pravednija distribucija.

Cantillonov Efekat predstavlja način na koji se naplaćuje dodatni porez svima koji rade za „nepromenjenu“ platu ili drže prvenstveno dolare ili eure kao deo svog bogatstva. Ovaj porez prenosi vrednost onima koji ulažu u finansijsku imovinu ili su preferirani dobavljači vlade. Bitcoin odvaja stvaranje novog novca od politike, čineći ovu situaciju mnogo poštenijom.

Kako Cantillonov Efekat Funkcioniše

Kada se poveća ponuda neke vrste novca, ima smisla da taj novi novac treba da ode u nečije ruke – ali čije? Da li bi trebao da pada kao kiša sa neba, da ga dobije neko na lutriji, ili ga predati posebnim interesnim grupama?

U našem savremenom monetarnom sistemu, ovaj novac nije uvek zajam za primaoce, tako da nekad ne trebaju da ga vrate.

Zabluda inflacije pomalo liči na MC Escher vodopad – dobro funkcioniše na papiru, ali ne govori skoro ništa korisno o tome kako stvarni svet funkcioniše.

Međutim, ova analiza zanemaruje to kako funkcionišu tržišta. Tamo gde novi novac ide prvo i način na koji se širi kroz ekonomiju, ima veliki uticaj na stvarno bogatstvo ljudi. Zašto? Kada se poveća novčana masa, cene se ne povećavaju odmah kao odraz ove činjenice. Umesto toga, povećavaju se polako, kako tržišta reaguju na novu ukupnu ponudu novca.

Prvi entiteti i ljudi koji prime novostvoreni novac mogu da ga potroše pre nego što je tržište reagovalo na bilo koji novi novac u sistemu prilagođavanjem cena. Kada oni kupuju stvari, dobijaju ih po niskim cenama jer cene još uvek ne podržavaju činjenicu da ima više novca u opticaju.

Jednom kada se novi novc nekoliko puta okrene, cene počinju da rastu, jer se više novčanih jedinica troši na isti broj dobara i usluga. Jedna od ‘cena’ u ekonomiji je plata ili zarada – i ova cena će da poraste, baš kao i sve druge. Međutim, ova cena raste sporije, kao rezultat ulaska novog novca u sistem, nego što je recimo, cena namirnica.

Kao rezultat ove neusklađenosti u vremenu porasta cena, oni koji primaju platu, tj. zaradu moraju da plaćaju više za svoje dnevne potrebe (poput namirnica), dok neko vreme primaju istu platu. Plate se prilagođavaju sporije od cena hrane. To dovodi do pada kupovne moći ljudi koji rade za platu..

Sve ovo proističe iz toga kako novi novac ulazi u sistem. Kada bi novi novac ušao u sistem samo putem zajmova direktno od centralne banke na plate ljudi, ti ljudi bi mogli da ga potroše pre nego što cene porastu, i samim tim bilo bi im bolje.

Na to kako raspodela novca utiče na bogatstvo, ukazao je Richard Cantillon u 18. veku, koji je gledao kako se ova dinamika odvija u Engleskoj kada je vlada štampala novac u njegovo vreme.

Izvrstan momak, g. Cantillon

Kako Bitcoin Rešava Nejednakost iz Cantillonovog Efekta

Da bismo razumeli kako Bitcoin rešava nejednakost, moramo da uporedimo kako se tradicionalne valute poput dolara ili eura distribuiraju u današnje vreme u odnosu na to kako se distribuiraju novi bitcoini.

Gotovo sva tradicionalna valuta koja je stvorena do današnjeg dana, prvo je distribuirana bankama i vladama. To je zato što su glavne komercijalne banke, poput JP Morgan i Citi, zauzvrat podržane od centralnih banaka poput Federalnih rezervi. Centralne banke poseduju ‘prese za štampanje’ – što znači da u svet mogu da ‘odštampaju’ (ili dodaju digitalno) neograničenu količinu svojih tradicionalnih valuta. Takođe su postavili pravila za komercijalne banke da ih podstaknu da pozajmljuju više ili manje dolara, što proširuje i ugovara ukupnu novčanu masu.

Budući da banke i vlade prve dobijaju novi novac, one odlučuju ko je drugi po redu koji može da iskoristi pogodnosti Cantillonovog Efekta. Tu na scenu dolaze lobisti, kao i moć koju donose njihove dobre konekcije sa finansijskom elitom. Lobisti osiguravaju da njihovi interesi imaju koristi od Cantillonovog Efekta, a veoma bogati, kao i korporacije, mogu da dobiju kredite od banaka po isplativim niskim kamatnim stopama.

Stvari mogu da se prilično zabrljaju kada vlada uskoči da preuzme “kontrolu” nad potrošnjom štampanog novca. Izvor: OpenDemocracy

Bitcoin-ov sistem eliminiše moć lobista i prednosti poznavanja pravog bankara, i stavlja ljude na mnogo ravnopravnije temelje. U Bitcoin-u, svaki ‘rudar’ na mreži ima jednake šanse da zaradi nagradu za novostvorene bitcoin-e na svakih 10 minuta. Svako može da postane rudar, jednostavnim kupovanjem hardvera i njegovim uključivanjem u utičnicu – daleko manje mukotrpan posao od lobiranja kod izabranih predstavnika da bi vam dodelili ugovor sa vladom. Rudari troše puno novca na električnu energiju i opremu da bi se takmičili za nagradu, a Bitcoin sistemu pružaju preko potrebnu uslugu: bezbednost. Bez rudara, Bitcoin-ov sistem ne bi funkcionisao.

Rudarenje bitcoin-a zahteva računar i struju – to je to.

U sistemu američkog dolara vidimo da političke veze proističu iz Cantillonovog Efekta. U Bitcoin sistemu vidimo da se pružaoci usluga (rudari) plaćaju za svoje usluge novostvorenim bitcoin-ima.

Naravno, ishodi Cantillonovog Efekta bi mogli da se promene tako što će političari da promene način na koji novi novac ulazi u sistem. Međutim, ovo ne rešava osnovni problem: neko drugi ima korist na tuđi račun.

Bitcoin sistem je daleko pravedniji jer koristi Cantillonov Efekat da bi uredno nagradio one koji pružaju korisnu uslugu za sve ostale: obezbeđivanje Bitcoin mreže.

Zamislite to ovako: u dolarskom sistemu, neka osoba šarmira političare ili bankare na pravim pozicijama da bi dobila povlašćen tretman na račun svih ostalih. U Bitcoin sistemu svi plaćaju po malo, da bi zaštitili svoje bankovne račune od krađe.

Uloga Vlade u Cantillonovom Efektu

Federalne vlade širom sveta su jedne od najvećih korisnika Cantillonovog Efekta, jer su u mogućnosti da vrlo lako dobiju zajmove od centralne banke svoje države. U SAD se to radi kada američko Ministarstvo finansija proda državne obveznice banci Federalnih rezervi. Federalne rezerve daju Ministarstvu finansija gomilu novoštampanog novca, a Ministarstvo finansija da Fed-u papir na kojem piše „mi ćemo vam isplatiti dug u to i to vreme sa određenom kamatom“. Možda je malo složenije od ovoga, ali to opisuje suštinu toga.

Budući da novac koji federalna vlada dobija nije postojao pre toga, ona može da ga potroši pre nego što cene počnu da rastu zbog tog novog novca koji ulazi u opticaj. To omogućava federalnoj vladi da ga troši na socijalne programe, policiju, vojsku, vojnu opremu za naoružavanje država poput Saudijske Arabije, čak i na ‘most iz nigde ka ničemu’, a da ne mora da koristi politički nepopularnu metodu: da poveća porez da bi to platila.

Umesto da povećaju poreske prihode za pokrivanje ove potrošnje, federalne vlade koriste Cantillonov Efekat za prenos kupovne moći od plata radnika srednje klase u vladin trezor. Na taj način inflacija i Cantillonov Efekat stvaraju skriveni porez na zarade i uštede novca.

Zaštitite Sebe od Cantillonovog Efekta

Zaštita svog života od Cantillonovog Efekta je zeznuta igra koju treba odigrati. Možete da pokušate da se približite izvoru novog novca, tako što ćete se nadmetati za državne ugovore ili raditi u vrhovima finansija. Možete da pokušate da igrate na visokim nivoima u trgovanju na berzi ili ulaganju u nekretnine, ali je verovatnije da ćete bankrotirati nego što ćete da se zaštitite.

Najlakši način da zaštitite sebe od nepravedne raspodele novog novca je potpuno odbijanje tog monetarnog sistema. Samo najstarije generacije koje danas žive mogu da se sete vremena kada je novac značio nešto drugo osim papira potkrepljenog ‘punom verom i kredibilitetom’ vlade i vojske. Mi smo tako uslovljeni da novac smatramo proizvodom naše vlade, ali naša zaštita od Cantillonovog Efekta zahteva gledanje novca kroz istoriju – čak i pre samo jednog veka.

Novac je nekada značio zlato – materijal koji nijedna vlada ne može magično da stvori u većoj količini, a koji zahteva ogroman napor da se pronađe i iskopa iz zemlje. Bitcoin je vrlo sličan zlatu po tome što niko ne može magično da ga stvori, i veoma ga je teško proizvesti više ‘rudarenjem’. Međutim, Bitcoin takođe putuje brzinom interneta, omogućavajući globalnu trgovinu na način na koji zlato jednostavno ne može.

Bitcoin i zlato – slični po karakteristikama ‘normalnog novca’, različiti po prenosivosti.

Da biste se zaštitili od Cantillonovog Efekta, potrebno je što je više moguće isključiti se iz nepravednih sistema tradicionalnih valuta, čuvajući bogatstvo u pravom novcu, poput zlata ili Bitcoin-a. Ovo je najmirniji način za ukidanje starog sistema i uvođenje novog, pravednijeg sistema.

Sažetak. Potpuna peer-to-peer verzija elektronskog novca omogućila bi slanje uplata putem interneta direktno od jedne strane ka drugoj bez posredovanja finansijskih institucija. Digitalni potpisi pružaju deo rešenja, ali se glavni benefiti gube ako je i dalje potrebna pouzdana treća strana za sprečavanje dvostruke potrošnje. Predlažemo rešenje problema dvostruke potrošnje korišćenjem peer-to-peer mreže. Mreža vremenski označava transakcije tako što ih hešuje u tekući lanac dokaza o radu (proof of work) temeljen na hešu, formirajući zapis koji se ne može promeniti bez ponovnog rada i objavljivanja dokaza o tom radu. Najduži lanac ne služi samo kao dokaz niza događaja, nego i kao dokaz da je taj niz događaja potvrđen od strane dela peer-to-peer mreže koja poseduju najveću zbirnu procesorsku snagu (CPU). Sve dok većinu procesorske snage kontrolišu čvorovi (nodes) koji ne sarađuju u napadu na mrežu, oni će generisati najduži lanac i nadmašiti napadače. Sama mreža zahteva minimalnu strukturu. Poruke kroz mrežu se prenose uz pretpostavku da svaki čvor čini maksimalan napor da poruku prenese u svom izvornom obliku i na optimalan način, a čvorovi mogu napustiti mrežu i ponovo joj se pridružiti po želji, prihvatajući najduži lanac dokaza o radu kao dokaz onoga što se dogodilo dok ih nije bilo.

1. Uvod

Trgovina na Internetu počela je da se oslanja skoro isključivo na finansijske institucije koje služe kao pouzdani posrednici pri obradi elektronskih plaćanja. Iako sistem radi dovoljno dobro za većinu transakcija i dalje trpi od inherentnih slabosti modela utemeljenog na poverenju.

Potpuno nepovratne transakcije zapravo nisu moguće, jer finansijske institucije ne mogu izbeći posredovanje u rešavanju eventualnih sporova. Troškovi posredovanja povećavaju troškove transakcija, ograničavaju minimalnu praktičnu veličinu transakcija i onemogućuju male, povremene transakcije jer postoji velika šteta zbog gubitka mogućnosti da se izvrše nepovratna plaćanja za nepovratne usluge. Uz mogućnost povraćaja transakcije, potreba za poverenjem raste. Trgovci moraju biti oprezni prema svojim kupcima i tražiti im više informacija nego što bi inače bilo neophodno. Određeni procenat prevara prihvaćen je kao neizbežan. Ovi troškovi i nepouzdanost plaćanja mogu se izbeći korišćenjem gotovine, ali ne postoji mehanizam za elektronsko plaćanje bez pouzdane treće strane.

Ono što je potrebno je elektronski sistem plaćanja zasnovan na kriptografskom dokazu umesto na poverenju, koji omogućava da bilo koje dve strane direktno i dobrovoljno međusobno trguju bez potrebe za posrednikom. Transakcije koje su nepovratne bi zaštitile prodavce od prevara, a escrow mehanizmi mogli bi se lako implementirati radi zaštite kupaca. U ovom dokumentu predlažemo rešenje problema dvostruke potrošnje korišćenjem peer-to-peer distribuiranog servera vremenskih oznaka (timestamp) za generisanje računarskog dokaza o hronološkom redosledu transakcija. Sistem je siguran sve dok pošteni čvorovi zajedno kontrolišu više procesorske snage procesora nego bilo koja udružena grupa napadačkih čvorova.

2. Transakcije

Elektronski novčić definišemo kao lanac digitalnih potpisa. Svaki vlasnik prenosi novčić na sledećeg digitalnim potpisivanjem heša prethodne transakcije i javnog ključa sledećeg vlasnika, dodajući ih potom na kraj novčića. Primalac transakcije može da verifikuje potpise, a time i lanac vlasništva.

Problem je naravno u tome što primalac ne može potvrditi da jedan od prethodnih vlasnika nije dva puta poslao isti novčić. Uobičajeno rešenje je uvođenje pouzdanog centralizovanog posrednika, kreatora novčića koji proverava sve transakcije. Nakon svake transakcije, novčić se mora vratiti kreatoru kako bi se izdao novi novčić i veruje se da samo za novčiće izdate direktno od kreatora možemo biti sigurni da nisu dva puta potrošeni. Problem sa ovim rešenjem je što sudbina čitavog novčanog sistema zavisi od kompanije koja kreira novčiće, jer svaka transakcija mora da prođe kroz nju, baš kao što je slučaj sa bankom.

Treba nam način da primalac bude siguran da prethodni vlasnici nisu potpisali nikakve ranije transakcije kojim bi potrošili taj novčić. Za naše potrebe, računamo transakciju koja se prva desila i ne zanimaju nas naredni pokušaji da se isti novčić ponovo pošalje. Jedini način da sa sigurnošću potvrdimo da taj novčić nije prethodno bio poslat je da imamo informacije o svim transakcijama koje su se ikada desile. U modelu baziranom na centalizovan kreatoru, taj kreator je imao informacije o svim transakcijama i odlučivao koja transakcija je prva stigla. Da bismo to postigli bez pouzdanog posrednika, transakcije moraju biti javno objavljene [1] i potreban nam je sistem u kojem učesnici mogu da se dogovore o jedinstvenoj istoriji redosleda kojim su transakcije primljene. Primaocu je potreban dokaz da se u trenutku dešavanja svake od transakcija većina čvorova složila oko toga da je baš ta transakcija bila ona koja je prva primljena.

3. Server vremenskih oznaka

Rešenje koje predlažemo počinje serverom vremenskih oznaka. Server vremenske oznake radi tako što uzima heš bloka podataka kojem će se dodeliti vremenska oznaka i objavi taj heš svima u mreži, slično kao u novinama ili kao post na Usenet mreži [2-5]. Vremenska oznaka očigledno dokazuje da su podaci morali postojati u to vreme kako bi ušli u haš. Svaka vremenska oznaka sadrži prethodnu vremensku oznaku u svom hešu, formirajući tako lanac, pri čemu svaka dodatna vremenska oznaka pojačava potvrde onih pre nje.

4. Dokaz o radu (Proof-of-Work)

Da bismo implementirali distribuirani server vremenskih oznaka na peer-to-peer principu, moraćemo da koristimo sistem dokaza o radu sličan Hashcash-u Adama Back-a [6], umesto Uneset postova ili novinskih objava. Dokaz o radu uključuje traženje vrednosti koja će, kada se hešuje, na primer pomoću SHA-256 heš funkcije, stvarati heš čiji binarni zapis započinje određenim brojem nula. Prosečna količina potrebnog rada eksponencijalno raste sa brojem potrebnih početnih nula, a može se proveriti izvršavanjem samo jedne heš fuknkcije.

Za našu mrežu vremenskih oznaka implementiramo dokaz o radu povećavajući nonce broja u bloku sve dok se ne pronađe ona vrednost nonce-a koja daje hešu bloka potreban broj početnih nula. Jednom kada se procesorska snaga utroši kako bi se zadovoljio dokaz o radu, blok se ne može izmeniti bez ponovljenog rada. Kako se kasniji blokovi vežu na taj blok, rad potreban da se on izmeni uključivao bi i ponovno obrađivanje svih blokova nakon njega.

Dokaz o radu takođe rešava problem utvrđivanja većine pri odlučivanju. Ako bi se ​​većina zasnivala na principu jednog glasa po IP adresi, mogao bi je narušiti svako ko je u stanju da glasa sa više IP adresa odjednom. Dokaz o radu u osnovi predstavlja jedan glas po jedinici procesorske snage. Većinska odluka je predstavljena najdužim lancem u čije je stvaranje zapravo investirano najviše rada prilikom dokazivanja. Ako većinu procesorske snage kontrolišu pošteni čvorovi, pošten lanac će rasti najbrže i nadmašiće sve konkurentske lance. Da bi izmenio neki od prethodnih blokova, napadač bi morao da ponovi dokaz o radu za taj blok i sve blokove nakon njega, a zatim da sustigne i nadmaši količinu rada poštenih čvorova. Kasnije ćemo pokazati da se dodavanjem novih blokova eksponencijalno smanjuje verovatnoća da će sporiji napadač uspeti da sustigne pošteni lanac.

Da bi se kompenzovalo povećanje brzine hardvera i promenljivo interesovanje ljudi za vođenje čvorova tokom vremena, težina obavljanja dokaza o radu (proof-of-work difficulty) određuje se prema prosečnom broju blokova krairanih za sat vremena. Ako se blokovi stvaraju prebrzo, težina se povećava.

5. Mreža

Koraci za vođenje mreže su sledeći:

1) Nove transakcije se prosleđuju svim čvorovima u mreži. 2) Svaki čvor prikuplja nove transakcije u blok. 3) Svaki čvor radi na pronalaženju dokaza o radu dovoljnog nivoa težine za svoj blok. 4) Kada čvor pronađe dokaz o radu, on emituje taj blok ka svim čvorovima. 5) Čvorovi prihvataju blok samo ako su sve transakcije u njemu ispravne i nisu već potrošene. 6) Čvorovi izražavaju prihvatanje bloka radeći na stvaranju sledećeg bloka u lancu, koristeći heš prihvaćenog bloka kao prethodni heš.

Čvorovi uvek smatraju da je najduži lanac ispravan i nastaviće da rade na njegovom produžavanju. Ako dva čvora istovremeno emituju različite verzije sledećeg bloka, neki čvorovi prvo mogu primiti jedan ili drugi blok. U tom slučaju svaki čvor radi na prvom koji je dobio, ali čuvaju drugu kariku lanca u slučaju da ona postane duža. Dilema će biti rešena kada se pronađe sledeći dokaz o radu i jedna karika postane duža; čvorovi koji su radili na drugoj karici lanca će se prebaciti na dužu kariku.

Emitovanje novih transakcija ne mora nužno doći do svih čvorova. Sve dok stižu do velikog broja čvorova, te transakcije će ući u blok. Slično važi i za blokove, ni oni ne moraju doći odmah do svih čvorova. Ako neki čvor propusti da primi informaciju o bloku, kada mu stigne sledeći blok,primetiće da je propustio jedan, pa će ga tražiti naknadno.

6. Podsticaj

Po pravilu, prva transakcija u bloku je posebna transakcija koja kreira novi novčić u vlasništvu kreatora bloka. Ovo daje podsticaj čvorovima da podrže mrežu i pruža način za početnu ubacivanje novčića u opticaj, budući da ne postoji centralno telo koje ih izdaje. Stalno dodavanje konstantne količine novih novčića liči na rudarenje zlata, gde rudari ulažu resurse kako bi izrudarili nove količine zlata i ubacili ih u opticaj. U našem slučaju ulaže se procesorsko vreme i električna energija.

Podsticaj se takođe može finansirati i transakcionim naknadama. Ako je iznos izlaznog dela transakcije manji od ulaznog, razliku čini naknada za transakciju koja se dodaje iznosu nagrade za kreatora bloka koji sadrži tu transakciju. Nakon što predefinisani broj novčića uđe u opticaj, podsticaj mogu u potpunosti činiti transakcione naknade, čime se sistem oslobađa inflacije.

Čvorovi su na ovaj način podstaknuti da ostanu pošteni. Ako je pohlepni napadač u stanju da angažuje više procesorske snage od svih poštenih čvorova zajedno, morao bi da bira između toga da poništi svoje izvršene transakcije i time prevari ljude ili da procesorsku snagu koristi za stvaranje novih novčića. On bi trebalo bi uvidi da je isplativije igrati po pravilima koja ga nagrađuju sa više novih novčića od svi drugi zajedno, nego da potkopava sistem i vrednost sopstvenog bogatstva.

7. Oslobađanje prostora na hard disku

Kada je dovoljno blokova dodato nakon poslednje transakcije novčića, prethodne transakcije tog novčića se mogu odbaciti kako bi se uštedeo prostor na hard disku. Kako bi se to ostvarilo bez razbijanja heša bloka, transakcije su hešovane u Merkleovo stablo (Merkle Tree) [7] [2] [5], gde je samo koren uključen u heš bloka. Stari blokovi se tada mogu sabiti uklanjanjem nepotrebnih grana drveta. Unutrašnji heševi ne moraju biti skladišteni.

Zaglavlje bloka bez transakcija bilo bi oko 80 bajtova. Ako pretpostavimo da su blokovi generisani svakih 10 minuta, 80 bajtova * 6 * 24 * 365 = 4,2 MB godišnje. Imajući u vidu činjenicu da se u 2008. godini računari uglavnom prodaju sa oko 2 GB RAM-a i Murov zakon koji predviđa trenutni rast od 1,2 GB godišnje, skladištenje ne bi trebalo da predstavlja problem čak i ako se zaglavlja bloka moraju čuvati u memoriji.

8. Pojednostavljena verifikacija plaćanja

Moguće je verifikovati plaćanja bez vođenja čitavog mrežnog čvora. Korisnik samo treba da sačuva kopiju zaglavlja blokova najdužeg lanca dokaza o radu, do koje može doći upitom ka mrežnim čvorovima dok se ne uveri da je dobio najduži lanac i dobije Merkleova granu

koja povezuje transakciju sa blokom u koji je uneta vremenska oznaka za tu transakciju. Ne može samostalno proveriti transakciju, ali povezujući je sa mestom u lancu može videti da je prihvaćena od strane čvora mreže i da su na njen blok dodati naknadni blokovi što dalje potvrđuje da ju je mreža prihvatila.

Kao takva, verifikacija je pouzdana sve dok pošteni čvorovi kontrolišu mrežu, ali je ranjiva ako napadač nadjača ostatak mreže. Čvorovi mreže mogu sami proveriti transakcije, ali napadačeve lažne transakcije mogu zavarati one koji koriste pojednostavljenu metodu verifikacije transakcija sve dok je on u stanju da nadjačava ostatak mreže. Jedna od strategija zaštite bila bi prihvatanje upozorenja čvorova mreže kada otkriju nevažeći blok, pri čemu bi korisnikov softver morao da preuzme ceo blok i sporne transakcije kako bi potvrdio nepravilnost. Biznisi koji primaju česte uplate će verovatno želeti da pokrenu i vode sopstvene čvorove radi brže verifikacije i potrebe da im sigurnost ne zavisi od drugih.

9. Kombinovanje i deljenje vrednosti

Iako bi bilo moguće pojedinačno rukovati novčićima, bilo bi nezgrapno kreirati zasebnu transakciju za svaki cent u toj transferu. Da biste dozvolili podelu i kombinovanje vrednosti, transakcije sadrže više ulaza i izlaza. Obično će postojati ili jedan ulaz iz veće prethodne transakcije ili više unosa koji kombinuju manje iznose, a najviše dva izlaza: jedan za samo plaćanje, a jedan koji vraća kusur, ako ga ima, nazad pošiljaocu.

Treba napomenuti da situacija u kojoj transakcija zavisi od nekoliko drugih transakcija, a te transakcije zavise od još mnogo više, ovde nije problem. Nikada ne postoji potreba za izdvajanjem istorije pojedinačne transakcije.

10. Privatnost

Tradicionalni bankarski model postiže odgovarajući nivo privatnosti ograničavanjem pristupa informacijama na strane uključene u transakciju i posrednika. Neophodnost javnog objavljivanja svih transakcija isključuje mogućnost primene pomenutog modela, ali privatnost se i dalje može zadržati na drugi način: čuvanjem javnih ključeva (public keys) anonimnim. Javnost može videti da neko šalje iznos nekom drugom, ali bez informacija koje povezuju transakciju sa bilo kim. Ovo je slično količini informacija koje objavljuju berze, gde se vreme i veličina pojedinačnih trgovina čine javnim, ali bez navođenja ko su stranke uključene u tu trgovinu.

Kao dodatni zaštitni zid, preporučljivo je koristiti novi par ključeva za svaku transakciju, kako ne bi bili povezane sa zajedničkim vlasnikom. Neka povezivanja su i dalje neizbežna kod transakcija sa više ulaza, koje nužno otkrivaju da su njihovi ulazi bili u vlasništvu istog vlasnika. Rizik je taj da bi se otkrivanjem vlasnik ključa mogle otkriti i ostale transakcije koje su pripadale tom vlasniku.

11. Proračuni

Razmatramo scenario u kome napadač pokušava da generiše alternativni lanac brže od poštenog lanca. Čak i ako se to postigne, to ne omogućuje proizvoljne promene u sistemu, poput stvaranje vrednosti ni iz čega ili uzimanje novca koji nikada nije pripadao napadaču. Pošteni čvorovi neće prihvatiti nevažeće transakcije kao uplatu i nikada neće prihvatiti blok koji ih sadrži. Napadač može samo pokušati da promeni jednu od svojih transakcija kako bi vratio novac koji je nedavno potrošio.

Trka između poštenog lanca i lanca napadača može se predstaviti kao binomska distribucija slučajne diskretne varijable (Binomial Random Walk). Uspešni ishod je da se pošten lanac produži za jedan blok, povećavajući svoje vođstvo za +1, a neuspešni ishod je da se napadačev lanac produži za jedan blok, smanjujući zaostatak za -1.

Verovatnoću da napadač nadoknadi određeni deficit možemo izraziti kroz problem kockareve propasti (Gambler’s Ruin Problem). Pretpostavimo da kockar sa neograničenim iznosom novca počinje sa zaostatkom i igra potencijalno beskonačan broj ponovljenih igara u pokušaju da nadoknadi zaostatak. Možemo izračunati verovatnoću za nadoknađivanje zaostatka ili da će napadač stići pošten lanac, na sledeći način [8]:

p= verovatnoća da pošten čvor pronađe sledeći blok q= verovatnoća da napadač pronađe sledeći blok qz= verovatnoća da će napadač ikada dostići z blokova zaostatka

S obzirom na našu pretpostavku da je p > q, verovatnoća pada eksponencijalno kako se povećava broj blokova koje napadač mora da nadoknadi. Sa šansama protiv njega, ako mu se u početku ne posreći, njegove šanse postaju manje i manje sa povećanjem zaostatka.

Sada razmatramo koliko primalac nove transakcije treba da čeka pre nego što postane

dovoljno siguran da pošiljalac ne može promeniti transakciju. Pretpostavljamo da je pošiljalac napadač koji želi da natera primaoca da veruje da mu je platio, a zatim nakon nekog vremena tu transakciju preusmeri ka sebi. Primalac će primetiti kada se to dogodi, ali pošiljalac se nada da će tad već biti prekasno.

Primalac generiše novi par ključeva i daje javni ključ pošiljaocu neposredno pre potpisivanja transakcije. Ovo sprečava pošiljaoca da unapred pripremi lanac blokova radeći na njemu neprekidno dok mu se ne posreći da stekne dovoljnu prednost i u tom trenutku izvrši transakciju. Kada se transakcija pošalje, nepošteni pošiljalac počinje tajno da radi na paralelnom lancu koji sadrži alternativnu verziju njegove transakcije.

Primalac čeka dok transakcija ne bude dodata u blok, i dok z blokova nije dodato nakon tog bloka. On ne zna tačno koliko je napadač napredovao, ali pod pretpostavkom da su pošteni blokovi kreirani očekivanom dinamikom, potencijalni napredak napadača će biti prikazan kao Poasonova distribucija sa očekivanom vrednošću:

Kako bismo izračunali verovatnoću da napadač ipak može da nadoknadi zaostatak, množimo gustinu verovatnoće za svaki nivo napretka koji je mogao da ostvari sa verovatnoćom da od tog trenutka može da potpuno nadoknadi zaostatak:

Preuređujemo formulu kako bismo izbegli sabiranje beskonačnog broja sabiraka zbog repa distribucije:

I konvertujemo u programski kod u programskom jeziku C…

Kroz par primera, vidimo da verovatnoća opada eksponencijalno sa porastom z.

Rešavanje za P < 0.1%…

12. Zaključak

Predložili smo sistem za elektronske transakcije bez oslanjanja na poverenje. Počeli smo sa uobičajenim šablonom i novčićima nastalim iz digitalnih potpisa, koji pruža snažnu kontrolu nad vlasništvom, ali je nepotpun bez načina da se spreči dvostruka potrošnja. Kako bismo ovo rešili, predložili smo peer-to-peer mrežu koja koristi dokaz o radu za čuvanje javne istorije transakcija čija izmena napadačima brzo postaje računski nepraktična ako pošteni čvorovi kontrolišu većinu procesorske snage. Mreža je robusna u svojoj nestrukturiranoj jednostavnosti. Svi čvorovi rade istovremeno uz malo koordinacije. Ne treba ih identifikovati, jer se poruke ne usmeravaju na jedno određeno mesto nego samo trebaju biti prenete uz maksimalan napor od strane čvorova da se taj prenos odradi na predviđen način. Čvorovi mogu da napuste i ponovo se pridruže mreži po želji, prihvatajući lanac dokaza o radu kao dokaz onoga što se dogodilo dok ih nije bilo. Oni glasaju svojom procesorskom snagom, izražavajući svoje prihvatanje validnih blokova time što pokušavaju da ih nadgrade novim blokovima i odbacuju nevažeće blokove odbijanjem ih nadgrađuju. Sva potrebna pravila i podsticaji mogu se nametnuti ovim mehanizmom postizanja konsenzusa.

The oil-in-water sensoris an instrument specially used to detect oil substances in water bodies. Its working principle is mainly based on the characteristic that oil substances will produce fluorescence under ultraviolet light. The following is a detailed explanation:

Principle Overview The oil-in-water sensor uses the characteristic that oil substances will produce fluorescence under ultraviolet light, and measures the fluorescence intensity to infer the concentration of oil substances. Specifically, the sensor uses ultraviolet light as the excitation light source to irradiate the water sample to be tested. After the oil substance absorbs ultraviolet light, it will stimulate fluorescence, and the fluorescence signal is received by the photo detector and converted into an electrical signal. By measuring the strength of the electrical signal, the concentration of oil substances in the water sample can be inferred.

Workflow Ultraviolet light irradiation: The ultraviolet light source inside the sensor emits ultraviolet light and irradiates it into the water sample to be tested.

Fluorescence generation: After the oil substance in the water sample absorbs ultraviolet light, it will stimulate fluorescence.

Fluorescence detection: The photo detector in the sensor measures the intensity of this fluorescence.

Signal conversion: The signal processing circuit converts the output of the photo detector into an electrical signal proportional to the amount of oil in the water. Data analysis: By analyzing the strength of the electrical signal, the concentration of oil substances in the water sample can be obtained.

Features and applications The oil in water sensor has high sensitivity and can detect soluble and falsifiable oils. It is suitable for a variety of water quality monitoring scenarios, such as oil field monitoring, industrial circulating water, condensate water, wastewater treatment, surface water stations, etc. In addition, it can also monitor the content of crude oil (benzene and benzene homologous) in water sources such as reservoirs and water plants in real time online, play an early warning role, and protect the safety of water sources.

Practical application The oil in water sensor has a wide range of functions in practical applications, including but not limited to the following aspects: Monitoring the water quality of water sources: ensuring the safety of drinking water, and timely discovering pollution sources and ensuring water supply safety by continuously monitoring oil substances in water sources. Monitoring sewage treatment plant emissions: ensuring that the discharge water quality of sewage treatment plants meets the emission standards to avoid secondary pollution to the environment. Monitoring rivers, lakes and other water bodies: assessing the pollution status and providing a basis for pollution control. Early warning and emergency response: It has real-time monitoring and early warning functions, and can issue an alarm in time when abnormal conditions are found, providing valuable time for emergency response and reducing losses caused by pollution. Scientific research: Through the monitoring data of this sensor, we can deeply understand the distribution, migration and transformation of oil substances in water bodies, and provide a scientific basis for environmental protection and governance.

In summary, the oil in water sensor monitors the oil content in water bodies through ultraviolet fluorescence method, has high sensitivity and broad application prospects, and is an indispensable and important tool in modern environmental monitoring and industrial production.

I’ve spent years chasing the promise of freedom.\ In startups. In faith communities. In movements that claimed to be for the people.

And yet — so often, that promise felt just out of reach.\ Conditional. Corporate. Sanitized.\ A freedom with fine print.

But here —\ Here in the thick of Bitcoin 2025, on Nostr, among misfits and builders and signal-bringers —\ something is alive.

It’s not a platform.\ It’s not a marketing strategy.\ It’s not another app promising to “empower” you while locking down your data and selling you out.

It’s freedom rooted in architecture.\ Decentralization not just as a buzzword —\ but as an expression of conviction.

A kind of freedom you can feel in your body:

• When you zap someone’s words because they moved you — not because an algorithm told you to.

• When your identity is yours — keys, not credentials.

• When no one can delete your story because you control the server, or because there is no server — just the relay of your choosing.

This isn’t utopia.\ There are egos. There’s noise. There’s still posturing.\ But it’s different.\ The center of gravity has shifted.

We’re no longer begging institutions to notice us.\ We’re building outside their jurisdiction.

And for the first time in a long time,\ freedom feels close.\ Tangible.\ Joyful.\ Alive.

This isn’t just about tech.\ It’s about trust.\ It’s about choosing to show up —\ to build\ to write\ to signal\ to keep going.

Even when it’s hard.\ Even when no one claps.

Because real freedom doesn’t come from being noticed.\ It comes from being sovereign.

And that’s something no one can take from me again.

The control of residual chlorine in swimming pools is an important part of water quality management, which aims to ensure the sanitation and safety of swimming pool water while avoiding discomfort to swimmers. Here are some key points about residual chlorine control in swimming pools:

Standards for residual chlorine According to the regulations of the national health supervision department, the residual chlorine in swimming pool water should be kept between 0.3mg/L-1.5mg/L. This range can not only ensure effective disinfection, but also avoid irritation to swimmers' skin and eyes caused by excessive residual chlorine. Too low residual chlorine will lead to incomplete disinfection and increase the risk of bacterial growth; while too high residual chlorine may cause human discomfort and even poisoning. The role of residual chlorine Residual chlorine is a residual disinfectant in swimming pool water, usually in the form of sodium hypocrite (NaClO). It has strong oxidizing properties and can effectively kill bacteria, viruses and other microorganisms in water, thereby ensuring the health of swimmers. In addition, residual chlorine can eliminate harmful substances such as organic matter and ammonia in water to keep the water clean.

Residual chlorine detection method The method of detecting residual chlorine in swimming pools usually uses test strips or test kits for qualitative or quantitative detection. In addition, online monitoring instruments can be used to monitor the residual chlorine in the swimming pool in real time. These methods can help managers promptly detect and deal with situations where the residual chlorine content is too high or too low, ensuring that the water quality of the swimming pool meets the standards.

Methods for controlling residual chlorine Reasonable addition of disinfectants: According to the water quality of the swimming pool and the number of swimmers, reasonable addition of disinfectants to control the residual chlorine content within the specified range.

Regular testing: Regularly test the residual chlorine in the swimming pool to promptly detect and deal with situations where the residual chlorine content is too high or too low.

Maintain swimming pool equipment: Regularly check and maintain swimming pool equipment to ensure the water treatment effect and circulation filtration are normal, and reduce residual disinfectants and other harmful substances in the water.

Do a good job in swimmer hygiene management: Strengthen swimmer hygiene management, require swimmers to shower and rinse their feet before entering the pool, and reduce pollution sources entering the swimming pool.

Solution for excessive residual chlorine If the residual chlorine content in the swimming pool exceeds the standard range, the following measures can be taken:

Use decorating agent: Use decorating agent to quickly restore the excessive residual chlorine in the swimming pool to the normal range (0.3~0.5mg/L). This method is applicable to excessive residual chlorine caused by excessive addition of chlorine disinfectant.

Adjust the water treatment process: According to the water quality, adjust the water treatment process appropriately, such as selecting the appropriate type and dosage of disinfectant, and adjusting operating parameters such as flow rate, pH value, etc., to reduce the generation of residual chlorine.

Strengthen equipment maintenance: Regularly maintain and maintain the water treatment equipment of the swimming pool to ensure its normal operation and disinfection effect.

Through the above methods, the residual chlorine content in the swimming pool can be effectively controlled to ensure water quality safety and protect the health of swimmers.

I recently acquired a new lens:

1959 Leica Summaron F2.8 35mm LTM.

1959 Leica Summaron 35mm f2.8 LTM mounted on my Fujifilm Xpro2 with LTM adapter made by Urth.

Technically, it was a trade. I helped a fellow Bitcoiner set up their Sparrow Wallet, Nostr stuff, and troubleshoot a few wallet issues, and in return, they gave me the lens.

It all started at a local Bitcoin meetup I went to about a week ago - my second time attending. I recognized a few faces from last time, but also saw some new ones. These meetups are refreshing - it’s rare to speak a common language about something like Bitcoin or Nostr. Most people still don’t get it. But they will.

Technology moves forward. Networks grow. Old cells die off.

During the meetup, someone noticed I had my Leica M262 with me and struck up a conversation. Said they had some old Leica lenses and gear at home, and wanted to show me.

Bitcoin and photography in one conversation? I’m down.

A day or so later, they sent me a photo of one of the lenses: a vintage Summaron LTM 35mm f/2.8 from 1959. I’d never seen or heard of one before. They asked if I could help them set up Sparrow and a Bitcoin node. In exchange, they’d give me the lens. Sounded like a good deal to me. Helping plebs with their setups feels like a duty anyway. I said, of course.

They invited me over - a pretty trusting move, which I appreciated. They had some great Bitcoin memorabilia: Fred Krueger’s The Big Bitcoin Book (even if the guy’s turned full shitcoiner), and some FTX sunglasses from Bitcoin 2022. Probably future collector’s items, lol.

We headed upstairs to work on setting up Sparrow Wallet on their Windows machine. I verified the software download first (which you should always do), then helped them create a new wallet using their Ledger Flex. They also had an older Ledger Nano X. The Flex setup was easy, but the Nano X gave us trouble. It turns out Ledger allows multiple wallets for the same asset, which can show up differently depending on how they’re configured. In Sparrow, only one wallet showed—none of the others.

I believe it had to do with the derivation path from the Ledger. If anyone knows a fix, let me know.

After a few hours of troubleshooting, I told them I couldn’t really recommend Ledger. The UX is a mess. They’d already heard similar things from other plebs too.

I suggested switching to the Blockstream Jade. It’s a solid Bitcoin-only device from a trustworthy team. That’s what you want in a hardware wallet.

But back to the lens…

Since it’s an LTM (Leica Thread Mount), I couldn’t mount it directly on my M262. Luckily, I remembered I had an Urth adapter that fits my Fujifilm X-Pro2. I don’t use the X-Pro2 much these days—it’s mostly been sidelined by the M262 - but this was the perfect excuse to bring it out again.

To test the lens, I shot everything wide open at f/2.8. Nothing crazy fast, but it’s the best way to see a lens’s character. And this one definitely has character. There’s a subtle softness and a kind of motion blur effect around the edges when wide open. At first, I wasn’t sure how I felt about it, but the more I shot, the more I liked it. It reminds me of Winogrand’s work in Winogrand Color - those messy, shifting edges that make the frame feel alive. It also helps soften the digital-ness of the camera sensor.

The focus throw is short and snappy - much tighter than my Summicron V3 35mm f/2. I really like how fast it is to use. The closest focusing distance is about 3.5 feet, so it’s not ideal for close-ups. And with the Urth adapter on the X-Pro2, the focal length ends up closer to 40mm.

The only thing that threw me off was the infinity lock. When the focus hits infinity, it physically locks - you have to press a small tab to unlock it. I’ve seen others complain about it, so I guess it’s just one of those old lens quirks. I’m getting used to it.

All the photos here were taken around where I live in South Carolina. Some during bike rides to the river for a swim, others while walking through the marshlands.

I try to make work wherever I am. You should be able to.

It’s about the light, the rhythm, the play - and having the motivation to actually go out and shoot.

Lens rating: 7.9/10

Soil moisture is a key factor that affects the structure and function of soil microbial communities. Here are some of the main aspects of how soil moisture affects microorganisms:

Affecting the Growth and Metabolism of Microorganisms Changes in soil moisture content directly affect the growth and metabolic activities of microorganisms. Under suitable moisture conditions, microorganisms are better able to carry out metabolic activities, thereby promoting the decomposition of soil organic matter and the transformation of nutrients. However, under extremely dry or overly wet conditions, the activity of microorganisms will be inhibited, resulting in a decline in soil functions.

Changing the Structure of Microbial Communities Changes in soil moisture conditions can lead to significant changes in the structure of microbial communities. For example, under drought conditions, the number of drought-tolerant microorganisms may increase to adapt to the water shortage environment. While under wet conditions, aerobic microorganisms may dominate. This change in community structure not only affects the soil's water retention capacity, but also other ecological functions of the soil.

Affecting the Stability of Soil Aggregates Soil aggregates are clumps formed by soil particles through physical, chemical and biological actions, and they have an important impact on the soil's water retention capacity. Soil microorganisms participate in the formation and stability of soil aggregates by secreting substances such as extracellular polymers. Appropriate soil moisture helps maintain the stability of soil aggregates, thereby improving the soil's water retention capacity. However, excessive moisture or drought may lead to the destruction of soil aggregates and reduce the soil's water retention capacity.

Regulating soil moisture dynamics Soil microorganisms can regulate the dynamic balance of soil moisture through their metabolic activities, such as decomposing organic matter and synthesizing exopolysaccharides. For example, some microorganisms can increase the water holding capacity of the soil by secreting exopolysaccharides, while others can release water by decomposing organic matter. These activities help maintain the stability of soil moisture and support plant growth.

Influencing the physical properties of soil Soil moisture can also indirectly affect the living environment of microorganisms by affecting the physical properties of the soil, such as pore structure and texture. Good soil pore structure is conducive to the penetration and storage of water, and also provides a suitable living space for microorganisms. Soil texture is closely related to the stability of aggregates. Sandy soils have poor aggregate stability and weak water retention capacity; while clay soils have good aggregate stability and strong water retention capacity.

In summary, soil moisture has many effects on microorganisms, including affecting the growth and metabolism of microorganisms, changing the structure of microbial communities, affecting the stability of soil aggregates, regulating soil moisture dynamics, and affecting the physical properties of soil. Therefore, maintaining suitable soil moisture conditions is of great significance for protecting the diversity and function of soil microbial communities and improving the water retention capacity of soil.

Distilled water has a wide range of applications in the medical field, mainly including the following aspects: Preparation of injection water Distilled water is an indispensable agent in medical institutions, used for the preparation of drugs, injection and washing of instruments, etc. In the medical process, sterile injection water is needed to flush wounds, prepare drugs, etc. The distilled water machine can ensure the purity of water and prevent microorganisms and harmful substances in the water from causing harm to patients.

Surgical wound flushing In breast cancer surgery, warm distilled water is used to flush surgical wounds. This practice helps to clean the wound, remove possible residual tumor cells, and use hypnotic effect to make tumor cells absorb water, swell, rupture, and necrotic, thereby preventing tumors from growing in the wound.

Cleaning and disinfection Distilled water has a certain disinfection and sterilization effect. It can be used to clean the skin, help eliminate bacteria on the skin surface, and is beneficial to the health of the skin. In addition, distilled water can also be used to clean and disinfect medical equipment to ensure the hygiene and safety of the medical environment.

Laboratory use In medical-related laboratories, distilled water is used to prepare experimental solutions, wash utensils and experimental instruments. These applications ensure the accuracy of experimental results while maintaining the sterile environment of the laboratory.

Moisturizing and Beauty Although not directly used in medical applications, distilled water is also used in skin care. It can be used as a basic moisturizer to help improve the symptoms of dry skin. In the field of medical beauty, distilled water is sometimes used for facial compresses to achieve calming, cooling, and swelling effects.

In summary, the application of distilled water in the medical field is multifaceted, from basic injection water preparation to complex surgical assistance to daily skin care, it has played an important role.

In this second installment of The Android Elite Setup tutorial series, we will cover installing the nostr:npub10r8xl2njyepcw2zwv3a6dyufj4e4ajx86hz6v4ehu4gnpupxxp7stjt2p8 on your #Android device and browsing for apps you may be interested in trying out.

Since the #Zapstore is a direct competitor to the Google Play Store, you're not going to be able to find and install it from there like you may be used to with other apps. Instead, you will need to install it directly from the developer's GitHub page. This is not a complicated process, but it is outside the normal flow of searching on the Play Store, tapping install, and you're done.

Installation

From any web browser on your Android phone, navigate to the Zapstore GitHub Releases page and the most recent version will be listed at the top of the page. The .apk file for you to download and install will be listed in the "Assets."

Tap the .apk to download it, and you should get a notification when the download has completed, with a prompt to open the file.

You will likely be presented with a prompt warning you that your phone currently isn't allowed to install applications from "unknown sources." Anywhere other than the Play Store is considered an "unknown source" by default. However, you can manually allow installation from unknown sources in the settings, which the prompt gives you the option to do.

In the settings page that opens, toggle it to allow installation from this source, and you should be prompted to install the application. If you aren't, simply go to your web browser's downloads and tap on the .apk file again, or go into your file browser app and you should find the .apk in your Downloads folder.

If the application doesn't open automatically after install, you will find it in your app drawer.

Home Page

Right at the top of the home page in the Zapstore is the search bar. You can use it to find a specific app you know is available in the Zapstore.

There are quite a lot of open source apps available, and more being added all the time. Most are added by the Zapstore developer, nostr:npub1wf4pufsucer5va8g9p0rj5dnhvfeh6d8w0g6eayaep5dhps6rsgs43dgh9, but some are added by the app developers themselves, especially Nostr apps. All of the applications we will be installing through the Zapstore have been added by their developers and are cryptographically signed, so you know that what you download is what the developer actually released.

The next section is for app discovery. There are curated app collections to peruse for ideas about what you may want to install. As you can see, all of the other apps we will be installing are listed in nostr:npub1wf4pufsucer5va8g9p0rj5dnhvfeh6d8w0g6eayaep5dhps6rsgs43dgh9's "Nostr" collection.

In future releases of the Zapstore, users will be able to create their own app collections.

The last section of the home page is a chronological list of the latest releases. This includes both new apps added to the Zapstore and recently updated apps. The list of recent releases on its own can be a great resource for discovering apps you may not have heard of before.

Installed Apps

The next page of the app, accessed by the icon in the bottom-center of the screen that looks like a clock with an arrow circling it, shows all apps you have installed that are available in the Zapstore. It's also where you will find apps you have previously installed that are ready to be updated. This page is pretty sparse on my test profile, since I only have the Zapstore itself installed, so here is a look at it on my main profile:

The "Disabled Apps" at the top are usually applications that were installed via the Play Store or some other means, but are also available in the Zapstore. You may be surprised to see that some of the apps you already have installed on your device are also available on the Zapstore. However, to manage their updates though the Zapstore, you would need to uninstall the app and reinstall it from the Zapstore instead. I only recommend doing this for applications that are added to the Zapstore by their developers, or you may encounter a significant delay between a new update being released for the app and when that update is available on the Zapstore.

Tap on one of your apps in the list to see whether the app is added by the developer, or by the Zapstore. This takes you to the application's page, and you may see a warning at the top if the app was not installed through the Zapstore.

Scroll down the page a bit and you will see who signed the release that is available on the Zapstore.

In the case of Primal, even though the developer is on Nostr, they are not signing their own releases to the Zapstore yet. This means there will likely be a delay between Primal releasing an update and that update being available on the Zapstore.

Settings

The last page of the app is the settings page, found by tapping the cog at the bottom right.

Here you can send the Zapstore developer feedback directly (if you are logged in), connect a Lightning wallet using Nostr Wallet Connect, delete your local cache, and view some system information.

We will be adding a connection to our nostr:npub1h2qfjpnxau9k7ja9qkf50043xfpfy8j5v60xsqryef64y44puwnq28w8ch wallet in part 5 of this tutorial series.

For the time being, we are all set with the Zapstore and ready for the next stage of our journey.

For those who still don't truly understand Bitcoin, it means you still don't understand what money is, who creates it, and why humans need money.

It's a scam that the education system doesn't teach this important subject, while we spend almost our entire lives trying to earn money. Therefore, I recommend following the money and studying Bitcoin seriously.

Why Bitcoin Matters

Saving is the greatest discovery in human history

Before humans learned to save, we were just animals living day to day. Saving is what makes humans different from other animals — the ability to think about the future and store for later.

Saving created civilization itself

Without saving, there would be no cities, no science, no art. Everything we call "progress" comes from the ability to save.

Money is the greatest creation in human history

It is the tool that has allowed human civilization to advance to this day. Money is the best tool humans use for saving.

Bitcoin is the best money ever created

It is the most perfect money humans have ever created. No one can control, manipulate, destroy it, and it is truly limited like time in life.

Bitcoin is like a black hole

That will absorb all value from the damaged financial system. It will draw stability and value to itself. Everything of value will flow into Bitcoin eventually.

Bitcoin is like Buddhism discovering truth

It helps understand the root problems of the current financial system and the emergence of many problems in society, just like Buddha who understood all suffering and the causes of suffering.

Bitcoin is freedom

Money is power, money controls human behavior. When we have money that preserves value and cannot be controlled, we will have intellectual freedom, freedom of expression, and the power to choose.

The debt that humanity has created today would take another thousand years to pay off completely

There is no way out and it's heading toward serious collapse. Bitcoin is the light that will help prevent humanity from entering another dark age.

Bitcoin cannot steal your time

It cannot be created from nothing. Every Bitcoin requires real energy and time to create.

Bitcoin is insurance that protects against mismanagement

It helps protect against currency debasement, economic depression, and failed policies. Bitcoin will protect your value.

Bitcoin is going to absorb the world's value

Eventually, Bitcoin will become the store of value for the entire world. It will absorb wealth from all assets, all prices, and all investments.

Exit The Matrix

We live in a financial Matrix. Every day we wake up and go to work, thinking we're building a future for ourselves. But in reality, we're just giving energy to a system that extracts value from us every second. Bitcoin is the red pill — it will open your eyes to see the truth of the financial world. Central banks are the architects of this Matrix — they create money from nothing, and we have to work hard to get it.

The education system has deceived us greatly. They teach us to work for money, but never teach us what money is. We spend 12-16 years in school, then spend our entire lives earning money, but never know what it is, who creates it, and why it has value. This is the biggest scam in human history.

We are taught to be slaves of the system, but not taught to understand the system.

The Bitcoin standard will end war

When you can't print money for war anymore, war becomes too expensive.

We are entering the Bitcoin Renaissance era

An era of financial and intellectual revival. Bitcoin is creating a new class of humans. People who understand and hold Bitcoin will become a new class with true freedom.

The Path to Financial Truth

Follow the money trail and you will see the truth: - Who controls money printing? - Why do prices keep getting higher? - Why are the poor getting poorer and the rich getting richer?

All the answers lie in understanding money and Bitcoin.

Studying Bitcoin is not just about investment — it's about understanding the future of currency and human society.

Don't just work for money. Understand money. Study Bitcoin.

If you don't understand money, you will be a slave to the system forever. If you understand Bitcoin, you will gain freedom.

Dear friend,

it seems like you have decided to turn your back on those walled gardens and set sails to enter uncharted territory. A world without walls, an open world, a world of beautiful chaos. At least for today, I don't intend guiding you out of the safe harbour onto the open, endless sea. Today, my only intent is sharing a few thoughts, before you depart.

As a wise man on Madeira once said, it's not so much about having the right answers, it's about asking the right questions. While I'm not certain whether I have found the right questions myself by now, let me share the current set with you:

• What causes the discomfort that drives you out of the walled garden onto the open sea?

• Are you trying to transfer from one walled garden to the next one, where the difference being a slightly friendlier colour on the wall?

• What are you hoping to find on the open sea that walled gardens cannot provide?

• What are you willing to sacrifice for freedom (of speech)?

• What will you need to keep the ship afloat?

• How will you react when you find yourself in the middle of a storm?

I sincerely believe that it's worthwile taking a step back before departing to reflect on the big picture and the underlying paradigm shift between walled gardens and nostr. This is not about building competitors to broken systems, this is not about mimicking centralised services, this is not about repeating the same mistakes over and over.

This is about building a new world, an open world without walled gardens and data silos.

Onwards!

Sa zadnjim cijenama koje je bitcoin dosegao 2017., optimističan scenarij za ulagače se možda čini toliko očitim da ga nije potrebno niti spominjati. Alternativno, možda se nekome čini glupo ulagati u digitalnu vrijednost koja ne počiva na nijednom fizičkom dobru ili vladi i čiji porast cijene su neki usporedili sa manijom tulipana ili dot-com balonom. Nijedno nije točno; optimističan scenarij za Bitcoin je uvjerljiv, ali ne i očit. Postoje značajni rizici kod ulaganja u Bitcoin, no, kao što planiram pokazati, postoji i ogromna prilika.

Geneza

Nikad u povijesti svijeta nije bilo moguće napraviti transfer vrijednosti među fizički udaljenim ljudima bez posrednika, poput banke ili vlade. 2008. godine, anonimni Satoshi Nakamoto je objavio 8 stranica rješenja na dugo nerješivi računalski problem poznat kao “Problem Bizantskog Generala.” Njegovo rješenje i sustav koji je izgradio - Bitcoin - dozvolio je, prvi put ikad, da se vrijednost prenosi brzo i daleko, bez ikakvih posrednika ili povjerenja. Implikacije kreacije Bitcoina su toliko duboke, ekonomski i računalski, da bi Nakamoto trebao biti prva osoba nominirana za Nobelovu nagradu za ekonomiju i Turingovu nagradu.

Za ulagače, važna činjenica izuma Bitcoina (mreže i protokola) je stvaranje novog oskudnog digitalnog dobra - bitcoina (monetarne jedinice). Bitcoini su prenosivi digitalni “novčići” (tokeni), proizvedeni na Bitcoin mreži kroz proces nazvan “rudarenje” (mining). Rudarenje Bitcoina je ugrubo usporedivo sa rudarenjem zlata, uz bitnu razliku da proizvodnja bitcoina prati unaprijed osmišljeni i predvidivi raspored. Samo 21 milijun bitcoina će ikad postojati, i većina (2017., kada je ovaj tekst napisan) su već izrudareni. Svake četiri godine, količina rudarenih bitcoina se prepolovi. Produkcija novih bitcoina će potpuno prestati 2140. godine.

Stopa inflacije —— Monetarna baza

Bitcoine ne podržava nikakva roba ili dobra, niti ih garantira ikakva vlada ili firma, što postavlja očito pitanje za svakog novog bitcoin ulagača: zašto imaju uopće ikakvu vrijednost? Za razliku od dionica, obveznica, nekretnina ili robe poput nafte i žita, bitcoine nije moguće vrednovati koristeći standardne ekonomske analize ili korisnost u proizvodnji drugih dobara. Bitcoini pripadaju sasvim drugoj kategoriji dobara - monetarnih dobara, čija se vrijednost definira kroz tzv. teoriju igara; svaki sudionik na tržištu vrednuje neko dobro, onoliko koliko procjenjuje da će ga drugi sudionici vrednovati. Kako bismo bolje razumjeli ovo svojstvo monetarnih dobara, trebamo istražiti podrijetlo novca.

Podrijetlo novca

U prvim ljudskim društvima, trgovina među grupama se vršila kroz robnu razmjenu. Velika neefikasnost prisutna u robnoj razmjeni je drastično ograničavala količinu i geografski prostor na kojem je bila moguća. Jedan od najvećih problema sa robnom razmjenom je problem dvostruke podudarnosti potražnje. Uzgajivač jabuka možda želi trgovati sa ribarom, ali ako ribar ne želi jabuke u istom trenutku, razmjena se neće dogoditi. Kroz vrijeme, ljudi su razvili želju za čuvanjem određenih predmeta zbog njihove rijetkosti i simbolične vrijednosti (npr. školjke, životinjski zube, kremen). Zaista, kako i Nick Szabo govori u svojem izvrsnom eseju o podrijetlu novca, ljudska želja za sakupljanjem predmeta pružila je izraženu evolucijsku prednost ranom čovjeku nad njegovim najbližim biološkim rivalom, neandertalcem - Homo neanderthalensis.

"Primarna i najbitnija evolucijska funkcija sakupljanja bila je osigurati medij za čuvanje i prenošenje vrijednosti".

Predmeti koje su ljudi sakupljali služili su kao svojevrsni “proto-novac,” tako što su omogućavale trgovinu među antagonističkim plemenima i dozvoljavale bogatsvu da se prenosi na sljedeću generaciju. Trgovina i transfer takvih predmeta bile su rijetke u paleolitskim društvima, te su oni služili više kao “spremište vrijednosti” (store of value) nego kao “medij razmjene” (medium of exchange), što je uloga koju danas igra moderni novac. Szabo objašnjava:

"U usporedbi sa modernim novcem, primitivan novac je imao jako malo “brzinu” - mogao je promijeniti ruke samo nekoliko puta u životu prosječnog čovjeka. Svejedno, trajni i čvrsti sakupljački predmet, što bismo danas nazvali “nasljeđe,” mogao je opstati mnogo generacija, dodajući znatnu vrijednost pri svakom transferu - i zapravo omogućiti transfer uopće".

Rani čovjek suočio se sa bitnom dilemom u teoriji igara, kada je odlučivao koje predmete sakupljati: koje od njih će drugi ljudi željeti? Onaj koji bi to točno predvidio imao bi ogromnu prednost u mogućnosti trgovine i akvizicije bogatsva. Neka američka indijanska plemena, npr. Naraganseti, specijalizirala su se u proizvodnji sakupljačkih dobara koja nisu imala drugu svrhu osim trgovine. Valja spomenuti da što je ranije predviđanje da će neko dobro imati takvu vrijednost, veća je prednost koju će imati onaj koji je posjeduje, zato što ju je moguće nabaviti jeftinije, prije nego postane vrlo tražena roba i njezona vrijednost naraste zajedno sa populacijom. Nadalje, nabava nekog dobra u nadi da će u budućnosti biti korišteno kao spremište vrijednosti, ubrzava upravo tu primjenu. Ova cirkularnost je zapravo povratna veza (feedback loop) koja potiče društva da se rapidno slože oko jednog spremišta vrijednosti. U terminima teorije igara, ovo je znano kao “Nashov ekvilibrij.” Postizanje Nashovog ekvilibrija za neko spremište vrijednosti je veliko postignuće za društvo, pošto ono znatno olakšava trgovinu i podjelu rada, i time omogućava napredak civilizacije.

Tisućljećima, kako su ljudska društva rasla i otvarala trgovinske puteve, različite aplikacije spremišta vrijednosti u individualnim društvima počele su se natjecati međusobno. Trgovci su imali izbor: čuvati svoju zaradu u spremištu vrijednosti vlastite kulture, ili one kulture sa kojom su trgovali, ili mješavini oboje. Benefit štednje u stranom spremištu vrijednosti bila je uvećana sposobnost trgovanja u povezanom stranom društvu. Trgovci koji su štedili u stranom spremištu vrijednosti su također imali dobrih razloga da potiču svoje društvo da ga prihvati, jer bi tako uvećali vrijednost vlastite ušteđevine. Prednosti “uvezene” tehnologije spremanja vrijednosti bile su prisutne ne samo za trgovce, nego i za sama društva. Kada bi se dvije grupe konvergirale u jedinstvenom spremištu vrijednosti, to bi značajno smanjilo cijenu troškova trgovine jednog s drugim, i samim time povećanje bogatstva kroz trgovinu. I zaista, 19. stoljeće bilo je prvi put da je najveći dio svijeta prihvatio jedinstveno spremište vrijednosti - zlato - i u tom periodu vidio najveću eksploziju trgovine u povijesti svijeta. O ovom mirnom periodu, pisao je John Maynard Keynes:

"Kakva nevjerojatna epizoda u ekonomskom napretku čovjeka… za svakog čovjeka iole iznadprosječnog, iz srednje ili više klase, život je nudio obilje, ugodu i mogućnosti, po niskoj cijeni i bez puno problema, više nego monarsima iz prethodnih perioda. Stanovnik Londona mogao je, ispijajući jutarnji čaj iz kreveta, telefonski naručiti razne proizvode iz cijele Zemlje, u količinama koje je želio, i sa dobrim razlogom očekivati njihovu dostavu na svoj kućni prag."

Svojstva dobrog spremišta vrijednosti

Kada se spremišta vrijednosti natječu jedno s drugim, specifična svojstva rade razliku koja daje jednom prednost nad drugim. Premda su mnoga dobra u prošlosti korištena kao spremišta vrijednosti ili kao “proto-novac,” određena svojstva su se pokazala kao posebno važna, i omogućila dobrima sa njima da pobijede. Idealno spremište vrijednosti biti će:

• Trajno: dobro ne smije biti kvarljivo ili lako uništeno. Tako naprimjer, žito nije idealno spremište vrijednosti.
• Prenosivo: dobro mora biti lako transportirati i čuvati, što omogućuje osiguranje protiv gubitka ili krađe i dopušta trgovinu na velike udaljenosti. Tako, krava je lošije spremište vrijednosti od zlatne narukvice.
• Zamjenjivo: jedna jedinica dobra treba biti zamjenjiva sa drugom. Bez zamjenjivosti, problem podudarnosti želja ostaje nerješiv. Time, zlato je bolje od dijamanata, jer su oni nepravilni u obliku i kvaliteti.
• Provjerljivo: dobro mora biti lako i brzo identificirano i testirano za autentičnost. Laka provjera povećava povjerenje u trgovini i vjerojatnost da će razmjena biti dovršena.
• Djeljivo: dobro mora biti lako djeljivo na manje dijelove. Premda je ovo svojstvo bilo manje važno u ranim društvima gdje je trgovina bila rijetka, postalo je važnije sa procvatom trgovine. Količine koje su se mijenjale postale su manje i preciznije.
• Oskudno: Monetarno dobro mora imati “cijenu nemoguću za lažirati,” kao što je rekao Nick Szabo. Drugim riječima, dobro ne smije biti obilno ili lako dostupno kroz proizvodnju. Oskudnost je možda i najvažnije svojstvo spremišta vrijednosti, pošto se izravno vezuje na ljudsku želju da sakupljamo ono što je rijetko. Ona je izvor vrijednosti u spremištu vrijednosti.
• Duge povijesti: što je dulje neko dobro vrijedno za društvo, veća je vjerojatnost da će biti prihvaćeno kao spremište vrijednosti. Dugo postojeće spremište vrijednosti biti će jako teško uklonjeno od strane došljaka, osim u slučaju sile (ratno osvajanje) ili ako je nova tehnologija znatno bolja u ostalim svojstvima.
• Otporno na cenzuru: novije svojstvo, sve više važno u modernom digitalnom svijetu sa sveprisutnim nadzorom, je otpornost na cenzuru. Drugim riječima, koliko je teško da vanjski agent, kao korporacija ili država, spriječi vlasnika dobra da ga čuva i koristi. Dobra koja su otporna na cenzuru su idealna za ljude koji žive u režimima koji prisilno nadziru kapital ili čine neke oblike mirne trgovine protuzakonitima.

Ova tablica ocjenjuje Bitcoin, zlato (gold) i fiat novac (kao što je euro ili dolar) po svojstvima izlistanim gore. Objašnjenje svake ocjene slijedi nakon tablice.

Trajnost:

Zlato je neosporeni kralj trajnosti. Velika većina zlata pronađenog kroz povijest, uključujući ono egipatskih faraona, opstaje i danas i vjerojatno će postojati i za tisuću godina. Zlatnici korišteni u antičko doba imaju značajnu vrijednost i danas. Fiat valute i bitcoini su digitalni zapisi koji ponekad imaju fizički oblik (npr. novčanice). Dakle, njihovu trajnost ne određuju njihova fizička svojstva (moguće je zamijeniti staru i oštećenu novčanicu za novu), nego institucije koje stoje iza njih. U slučaju fiat valuta, mnoge države su nastale i nestale kroz stoljeća, i valute su nestale s njima. Marke iz Weimarske republike danas nemaju vrijednost zato što institucija koja ih je izdavala više ne postoji. Ako je povijest ikakav pokazatelj, ne bi bilo mudro smatrati fiat valute trajnima dugoročno; američki dolar i britanska funta su relativne anomalije u ovom pogledu. Bitcoini, zato što nemaju instituciju koja ih održava, mogu se smatrati trajnima dok god mreža koja ih osigurava postoji. Obzirom da je Bitcoin još uvijek mlada valuta, prerano je za čvrste zaključke o njegovoj trajnosti. No, postoje ohrabrujući znakovi - prominente države su ga pokušavale regulirati, hakeri ga napadali - usprkos tome, mreža nastavlja funkcionirati, pokazujući visok stupanj antifragilnosti.

Prenosivost:

Bitcoini su najprenosivije spremište vrijednosti ikad. Privatni ključevi koji predstavljaju stotine milijuna dolara mogu se spremiti na USB drive i lako ponijeti bilo gdje. Nadalje, jednako velike sume mogu se poslati na drugi kraj svijeta skoro instantno. Fiat valute, zbog svojeg temeljno digitalnog oblika, su također lako prenosive. Ali, regulacije i kontrola kapitala od strane države mogu ugroziti velike prijenose vrijednosti, ili ih usporiti danima. Gotovina se može koristiti kako bi se izbjegle kontrole kapitala, ali onda rastu rizik čuvanja i cijena transporta. Zlato, zbog svojeg fizičkog oblika i velike gustoće, je najmanje prenosivo. Nije čudo da većina zlatnika i poluga nikad ne napuste sefove. Kada se radi prijenos zlata između prodavača i kupca, uglavnom se prenosi samo ugovor o vlasništvu, ne samo fizičko zlato. Prijenos fizičkog zlata na velike udaljenosti je skupo, riskantno i sporo.

Zamjenjivost:

Zlato nam daje standard za zamjenjivost. Kada je rastopljeno, gram zlata je praktički nemoguće razlikovati od bilo kojeg drugog grama, i zlato je oduvijek bilo takvo. S druge strane, fiat valute, su zamjenjive samo onoliko koliko njihova institucija želi da budu. Iako je uglavnom slučaj da je novčanica zamjenjiva za drugu istog iznosa, postoje situacije u kojima su velike novčanice tretirane drukčije od malih. Naprimjer, vlada Indije je, u pokušaju da uništi neoporezivo sivo tržište, potpuno oduzela vrijednost novčanicama od 500 i 1000 rupija. To je uzrokovalo da ljudi manje vrednuju te novčanice u trgovini, što je značilo da više nisu bile zaista zamjenjive za manje novčanice. Bitcoini su zamjenjivi na razini mreže; svaki bitcoin je pri prijenosu tretiran kao svaki drugi. No, zato što je moguće pratiti individualne bitcoine na blockchainu, određeni bitcoin može, u teoriji, postati “prljav” zbog korštenja u ilegalnoj trgovini, te ga trgovci ili mjenjačnice možda neće htjeti prihvatiti. Bez dodatnih poboljšanja oko privatnosti i anonimnosti na razini mrežnog protokola, bitcoine ne možemo smatrati jednako zamjenjivim kao zlato.

Mogućnost provjere:

Praktično gledajući, autentičnost fiat valuta i zlata je prilično lako provjeriti. Svejedno, i usprkos pokušajima da spriječe krivotvorenje novčanica, i dalje postoji potencijal prevare za vlade i njihove građane. Zlato također nije imuno na krivotvorenje. Sofisticirani kriminalci su koristili pozlaćeni tungsten kako bi prevarili kupce zlata. Bitcoine je moguće provjeriti sa matematičkom sigurnošću. Korištenjem kriptografskih potpisa, vlasnik bitcoina može javno demonstrirati da posjeduje bitcoine koje tvrdi da posjeduje.

Djeljivost:

Bitcoine je moguće podijeliti u stotinu milijuna manjih jedinica (zvanih satoshi), i prenositi takve (no, valja uzeti u obzir ekonomičnost prijenosa malih iznosa, zbog cijene osiguravanja mreže - “network fee”). Fiat valute su tipično dovoljno djeljive na jedinice sa vrlo niskom kupovnom moći. Zlato, iako fizički i teoretski djeljivo, postaje teško za korištenje kada se podijeli na dovoljno male količine da bi se moglo koristiti u svakodnevnoj trgovini.

Oskudnost:

Svojstvo koje najjasnije razlikuje Bitcoin od fiat valuta i zlata je njegova unaprijed definirana oskudnost. Od početka, konačna količina bitcoina nikad neće biti veća od 21 milijun. To daje vlasnicima bitcoina jasan i znan uvid u postotak ukupnog vlasništva. Naprimjer, vlasnik 10 bitcoina bi znao da najviše 2,1 milijuna ljudi (manje od 0.03% populacije) može ikad imati isto bitcoina kao i on. Premda je kroz povijest uvijek bilo oskudno, zlato nije imuno na povećanje ukupne količine. Ako se ikad izumi nova, ekonomičnija metoda rudarenja ili proizvodnje zlata, ukupna količina zlata bi se mogla dramatično povećati (npr. rudarenje morskog dna ili asteroida). Na kraju, fiat valute, relativno nov izum u povijesti, pokazale su se sklonima konstantnim povećanjima u količini. Države su pokazale stalnu sklonost inflaciji monetarne kvantitete kako bi rješavale kratkoročne političke probleme. Inflacijske tendencije vlada diljem svijeta čine fiat valute gotovo sigurnim da će gubiti vrijednost kroz vrijeme.

Etablirana povijest:

Nijedno monetarno dobro nema povijest kao zlato, koje je imalo vrijednost za cijelog trajanja ljudske civilizacije. Kovanice izrađene u antičko doba i danas imaju značajnu vrijednost. Ne može se isto reći za fiat valute, koje su same relativno nova povijesna anomalija. Od njihovog početka, fiat valute su imale gotovo univerzalni smjer prema bezvrijednosti. Korištenje inflacije kao podmuklog načina za nevidljivo oporezivanje građana je vječita kušnja kojoj se skoro nijedna država u povijesti nije mogla oduprijeti. Ako je 20. stoljeće, u kojem je fiat novac dominirao globalni monetarni poredak, demonstriralo neku ekonomsku istinu, to je onda bila ta da ne možemo računati na fiat novac da održi vrijednost u dužem ili srednjem vremenskom periodu. Bitcoin, usprkos svojoj novosti, je preživio dovoljno testova tržišta da postoji velika vjerojatnost da neće nestati kao vrijedno dobro. Nadalje, Lindy efekt govori da što duže Bitcoin bude korišten, to će veća biti vjera u njega i njegovu sposobnost da nastavi postojati dugo u budućnost. Drugim riječima, društvena vjera u monetarno dobro je asimptotička, kao u grafu ispod:

Ako Bitcoin preživi prvih 20 godina, imat će gotovo sveopće povjerenje da će trajati zauvijek, kao što ljudi vjeruju da je internet trajna stvar u modernom svijetu.

Otpor na cenzuru

Jedan od najbitnijih izvora za ranu potražnju bitcoina bila je njegova upotreba u ilegalnoj kupovini i prodaji droge. Mnogi su zato pogrešno zaključili da je primarna potražnja za bitcoinima utemeljena u njihovoj prividnoj anonimnosti. Međutim, Bitcoin nije anonimna valuta; svaka transakcija na mreži je zauvijek zapisana na javnom blockchainu. Povijesni zapis transakcija dozvoljava forenzičkoj analizi da identificira izvore i tijek sredstava. Takva analiza dovela je do uhićenja počinitelja zloglasne MtGox pljačke. Premda je istina da dovoljno oprezna i pedantna osoba može sakriti svoj identitet koristeći Bitcoin, to nije razlog zašto je Bitcoin bio toliko popularan u trgovini drogom.

Ključno svojstvo koje čini Bitcoin najboljim za takve aktivnosti je njegova agnostičnost i nepotrebnost za dozvolom (“premissionlessness”) na mrežnoj razini. Kada se bitcoini prenose na Bitcoin mreži, ne postoji nitko tko dopušta transakcije. Bitcoin je distribuirana peer-to-peer (korisnik-korisniku) mreža, i samim time dizajnirana da bude otporna na cenzuru. Ovo je u velikom kontrastu sa fiat bankarskim sustavom, u kojem države reguliraju banke i ostale institucije prijenosa novca, kako bi one prijavljivale i sprječavale protuzakonito korištenje monetarnih dobara. Klasičan primjer regulacije novca su kontrole kapitala. Npr., bogati milijunaš će vrlo teško prenijeti svoje bogatstvo u novu zemlju, kada bježi iz opresivnog režima. Premda zlato nije izdano i proizvedeno od države, njegova fizička priroda ga čini teško prenosivim kroz prostor, i samim time ga je daleko lakše regulirati nego Bitcoin. Indijski Akt kontrole zlata je primjer takve regulacije.

Bitcoin je odličan u većini gore navedenih svojstava, što mu omogućava da bude marginalno bolji od modernih i drevnih monetarnih dobara, te da pruži poticaje za svoje rastuće društveno usvajanje. Specifično, moćna kombinacija otpornosti na cenzuru i apsolutne oskudnosti bila je velika motivacija za bogate ulagače koji su uložili dio svojeg bogatstva u Bitcoin.

Evolucija novca

U modernoj monetarnoj ekonomiji postoji opsesija sa ulogom novca kao medija razmjene. U 20. stoljeću, države su monopolizirale izdavanje i kontrolu novca i kontinuirano potkopavale njegovo svojstvo spremišta vrijednosti, stvarajući lažno uvjerenje da je primarna svrha novca biti medij razmjene. Mnogi su kritizirali Bitcoin, govoreći da je neprikladan da bude novac zato što mu je cijena bila previše volatilna za medij razmjene. No, novac je uvijek evoluirao kroz etape; uloga spremišta vrijednosti je dolazila prije medija razmjene. Jedan od očeva marginalističke ekonomije, William Stanley Jevons, objašnjava:

"Povijesno govoreći… čini se da je zlato prvo služilo kao luksuzni metal za ukras; drugo, kao sačuvana vrijednost; treće, kao medij razmjene; i konačno, kao mjerilo vrijednosti."

U modernoj terminologiji, novac uvijek evoluira kroz četiri stadija:

1. Kolekcionarstvo: U prvoj fazi svoje evolucije, novac je tražen samo zbog svojih posebnih svojstava, uglavnom zbog želja onog koji ga posjeduje. Školjke, perlice i zlato su bili sakupljani prije nego su poprimili poznatije uloge novca.
2. Spremište vrijednosti: Jednom kada je novac tražen od dovoljnog broja ljudi, biti će prepoznat kao način za čuvanje i spremanje vrijednosti kroz vrijeme. Kada neko dobro postane široko korišteno kao spremište vrijednosti, njegova kupovna moć raste sa povećanom potražnjom za tu svrhu. Kupovna moć spremišta vrijednosti će u jednom trenutku doći do vrhunca, kada je dovolno rašireno i broj novih ljudi koji ga potražuju splasne.
3. Sredstvo razmjene: Kada je novac potpuno etabliran kao spremište vrijednosti, njegova kupovna moć se stabilizira. Nakon toga, postane prikladno sredstvo razmjene zbog stabilnosti svoje cijene. U najranijim danima Bitcoina, mnogi ljudi nisu shvaćali koju buduću cijenu plaćaju koristeći bitcoine kao sredstvo razmjene, umjesto kao novonastalo spremište vrijednosti. Poznata priča o čovjeku koji je za 10,000 bitcoina (vrijednih oko 94 milijuna dolara kada je ovaj članak napisan) za dvije pizze ilustrira ovaj problem.
4. Jedinica računanja vrijednosti: Jednom kada je novac široko korišten kao sredstvo razmjene, dobra će biti vrednovana u njemu, tj. većina cijena će biti izražena u njemu. Uobičajena zabluda je da je većinu dobara moguće zamijeniti za bitcoine danas. Npr., premda je možda moguće kupiti šalicu kave za bitcoine, izlistana cijena nije prava bitcoin cijena; zapravo se radi o cijeni u državnoj valuti koju želi trgovac, preračunatu u bitcoin po trenutnoj tržišnoj cijeni. Kad bi cijena bitcoina pala u odnosu na valutu, vrijednost šalice izražena u bitcoinima bi se povećala. Od trenutka kada trgovci budu voljni prihvaćani bitcoine kao platežno sredstvo, bez obraćanja pažnje na vrijednost bitcoina u državnoj fiat valuti, moći ćemo reći da je Bitcoin zaista postao jedinica računanja vrijednosti.

Monetarna dobra koja još nisu jedinice računanja vrijednosti možemo smatrati “djelomično monetiziranima.” Danas zlato ima takvu ulogu, jer je spremište vrijednosti, ali su mu uloge sredstva razmjene i računanja vrijednosti oduzete intervencijama država. Moguće je također da se jedno dobro koristi kao sredstvo razmjene, dok druga ispunjavaju ostale uloge. To je tipično u zemljama gdje je država disfunkcionalna, npr. Argentina ili Zimbabwe. U svojoj knjizi, Digitalno zlato, Nathaniel Popper piše:

"U Americi, dolar služi trima funkcijama novca: nudi sredstvo razmjene, jedinicu za mjerenje vrijednosti dobara, i mjesto gdje se može čuvati vrijednosti. S druge strane, argentinski peso je korišten kao sredstvo razmjene (za svakodnevne potrebe), ali ga nitko nije koristio kao spremište vrijednosti. Štednja u pesosima bila je ekvivalent bacanja novca. Zato su ljudi svu svoju štednju imali u dolarima, jer je dolar bolje čuvao vrijednost. Zbog volatilnosti pesosa, ljudi su računali cijene u dolarima, što im je pružalo pouzdaniju jedinicu mjerenja kroz vrijeme."

Bitcoin je trenutno u fazi tranzicije iz prvog stadija monetizacije u drugi. Vjerojatno će proći nekoliko godina prije nego Bitcoin pređe iz začetaka spremišta vrijednosti u istinski medij razmjene, i put do tog trenutka je još uvijek pun rizika i nesigurnosti. Važno je napomenuti da je ista tranzicija trajala mnogo stoljeća za zlato. Nitko danas živ nije doživio monetizaciju dobra u realnom vremenu (kroz koju Bitcoin prolazi), tako da nemamo puno iskustva govoriti o putu i načinu na koji će se monetizacija dogoditi.

Put monetizacije

Kroz proces monetizacije, monetarno dobro će naglo porasti u kupovnoj moći. Mnogi su tako komentirali da je uvećanje kupovne moći Bitcoina izgledalo kao “balon” (bubble). Premda je ovaj termin često korišten kako bi ukazao na pretjeranu vrijednosti Bitcoina, sasvim slučajno je prikladan. Svojstvo koje je uobičajeno za sva monetarna dobra jest da je njihova kupovna moć viša nego što se može opravdati samo kroz njihovu uporabnu vrijednost. Zaista, mnogi povijesni novci nisu imali uporabnu vrijednost. Razliku između kupovne moći i vrijednosti razmjene koju bi novac mogao imati za svoju inherentnu korisnost, možemo razmatrati kao “monetarnu premiju.” Kako monetarno dobro prolazi kroz stadije monetizacije (navedene gore), monetarna premija raste. No, ta premija ne raste u ravnoj i predvidivoj liniji. Dobro X, koje je bilo u procesu monetizacije, može izgubiti u usporedbi sa dobrom Y koje ima više svojstava novca, te monetarna premija dobra X drastično padne ili potpuno nestane. Monetarna premija srebra je skoro potpuno nestala u kasnom 19. stoljeću, kada su ga vlade diljem svijeta zamijenile zlatom kao novcem.

Čak i u odsustvu vanjskih faktora, kao što su intervencije vlade ili druga monetarna dobra, monetarna premija novog novca neće ići predvidivim putem. Ekonomist Larry White primijetio je:

"problem sa pričom “balona,” naravno, je da je ona konzistentna sa svakim putem cijene, i time ne daje ikakvo objašnjenje za specifičan put cijene"

Proces monetizacije opisuje teorija igara; svaki akter na tržištu pokušava predvidjeti agregiranu potražnju ostalih aktera, i time buduću monetarnu premiju. Zato što je monetarna premija nevezana za inherentnu korisnost, tržišni akteri se uglavnom vode za prošlim cijenama da bi odredili je li neko dobro jeftino ili skupo, i žele li ga kupiti ili prodati. Veza trenutne potražnje sa prošlim cijenama naziva se “ovisnost o putu” (path dependence); ona je možda najveći izvor konfuzije u shvaćanju kretanja cijena monetarnih dobara.

Kada kupovna moć monetarnog dobra naraste zbog većeg i šireg korištenja, očekivanja tržišta o definicijama “jeftinog” i “skupog” se mijenjaju u skladu s time. Slično tome, kada cijena monetarnog dobra padne, očekivanja tržišta mogu se promijeniti u opće vjerovanje da su prethodne cijene bile “iracionalne” ili prenapuhane. Ovisnost o putu novca ilustrirana je riječima poznatog upravitelja fondova s Wall Streeta, Josha Browna:

"Kupio sam bitcoine kada su koštali 2300 USD, i to mi se udvostručilo gotovo odmah. Onda sam počeo govoriti kako “ne mogu kupiti još” dok im je cijena rasla, premda sam znao da je to razmišljanje bazirano samo na cijenu po kojoj sam ih kupio. Kasnije, kada je cijena pala zbog kineske regulacije mjenjačnica, počeo sam si govoriti, “Odlično, nadam se da će još pasti da mogu kupiti još.”"

Istina leži u tome da su ideje “jeftinog” i “skupog” zapravo besmislene kada govorimo o monetarnim dobrima. Cijena monetarnog dobra ne reflektira njegovu stopu rasprostanjenosti ili korisnosti, nego mjeru koliko je ono široko prihvaćeno da ispuni razne uloge novca.

Dodatna komplikacija u ovom aspektu novca je činjenica da tržišni akteri ne djeluju samo kao nepristrani promatrači koji pokušavaju kupiti i prodati u iščekivanju budućih kretanja monetarne premije, nego i kao aktivni proponenti. Pošto ne postoji objektivno “točna” monetarna premija, širiti dobar glas o superiornijim svojstvima nekog monetarnog dobra je efektivnije nego za obična dobra, čija vrijednost je u konačnici vezana na njegovu osnovnu korisnost. Religiozni zanos sudionika na Bitcoin tržištu vidljiv je na raznim internetskim forumima, gdje Bitcoineri aktivno promoviraju benefine Bitcoina i bogatstvo koje je moguće ostvariti investiranjem u njega. Promatrajući Bitcoin tržište, Leigh Drogen komentira:

"To je prepoznatljivo svima kao religija - priča koju si pričamo i oko koje se slažemo. Religija je krivulja na grafu prihvaćanja o kojoj trebamo razmišljati. Sustav je gotovo savršen - onog trenutka kada netko pristupi krugu Bitcoinera, to će reći svima i nastaviti širiti riječ. Onda njihovi prijatelji pristupe i nastave širiti riječ."

Premda usporedba sa religijom može staviti Bitcoin u iracionalno svjetlo, potpuno je racionalno za individualnog vlasnika da širi dobru vijest o superiornom monetarnom dobru, i za šire društvo da se standardizira oko njega. Novac djeluje kao temelj za svu trgovinu i štednju; tako da prihvaćanje superiornog oblika novca ima ogromne multiplicirajuće benefite za stvaranje bogatstva za sve članove društva.

Oblik monetizacije

U članku o Spekulativnom prihvaćanju Bitcoina / teorije cijene, Michael Casey postulira da rastući Gartner hype ciklusi predstavljaju faze standardne S-krivulje prihvaćanja novih tehnologija, koje su bile prisutne kod mnogih transformacijskih tehnologija dok su postajale uobičajene u društvu.

Svaki Gartner hype ciklus počinje sa eksplozijom entuzijazma za novom tehnologijom, a cijenu podižu oni sudionici na tržištvu koji su “dostupni” u toj fazi. Najraniji kupci u Gartner hype ciklusu obično imaju jaku vjeru o transformacijskoj prirodi tehnologije u koju ulažu. S vremenom, tržište dosegne vrhunac entuzijazma kako se količina novih kupaca iscrpljuje, te kupovinom počnu dominirati spekulatori koji su više zainteresirani u brze profite nego u samu tehnologiju.

Nakon vrha hype ciklusa, cijene rapidno padaju dok spekulativno ludilo ustupa mjesto očajavanju, javnoj poruzi i osjećaju da tehnologija nije uopće bila transformacijska. S vremenom, cijena dosegne dno i formira plato na kojem se originalnim ulagačima, koji su imali snažno uvjerenje, pridružuju nove grupe ljudi koji su izdržali bol kraha cijena i koji cijene važnost same tehnologije.

Plato traje neko vrijeme i formira, kako Casey kaže, “stabilnu, dosadnu dolinu.” Za ovo vrijeme, javni interes za tehnologiju opada, no nastaviti će se razvijati i snažna zajednica uvjerenja će polako rasti. Tada, postavlja se nova baza za sljedeću iteraciju hype ciklusa, dok vanjski promatrači prepoznaju da tehnologija i dalje postoji i da ulaganje u nju možda nije onoliko rizično kao što se činilo za vrijeme pada cijene. Sljedeća iteracija hype ciklusa donosi mnogo veći broj novih ljudi, pa je i ciklus daleko veći u svojoj magnitudi.

Jako mali broj ljudi koji sudjeluju u Gartner hype ciklusu će točno predvidjeti koliko će visoko cijena porasti za vrijeme ciklusa. Cijene često dosegnu razine koje bi se činile apsurdnima većini ulagača u raniji stadijima ciklusa. Kada ciklus završi, mediji tipično atribuiraju pad cijene nekoj od aktualnih drušvenih tema. Premda takva tema može biti okidač pada, ona nikad nije temeljni razlog zašto ciklus završava. Gartner hype ciklusi završavaju kada je količina dostupnih novih sudionika na tržištu iscrpljena.

Zanimljivo je da je i zlato nacrtalo klasičan graf Gartner hype ciklusa od kasnih 1970-ih do ranih 2000-ih. Moguće je spekulirati da je hype ciklus osnovna socijalna dinamika oko procesa monetizacije.

Gartner kohorte

Od početka trgovanja Bitcoina na mjenjačnicama 2010. godine, Bitcoin tržište je svjedočilo četirima velikim Gartner hype ciklusima. U retrospektivi, možemo vrlo precizno identificirati grupe cijena prethodnih hype ciklusa Bitcoin tržišta. Također, možemo kvalitativno odrediti kohorte ulagača koje su povezane sa svakom iteracijom prethodnih ciklusa.

0 USD –1 USD (2009. – 3. mjesec 2011.): Prvi hype ciklus u Bitcoin tržištu dominirali su kriptografi, računalni znanstvenici i cypherpunkovi koji su od početka bili spremni razumijeti važnost nevjerojatnog izuma Satoshija Nakamotoa, i koji su bili pioniri u potvrđivanju da Bitcoin protokol nema tehničkih mana.

1 USD - 30 USD (3. mjesec 2011. – 7. mjesec. 2011.): Drugi ciklus privukao je rane entuzijaste oko novih tehnologija kao i stabilan pritok ideološki motiviranih ulagača koji su bili oduševljeni idejom novca odvojenog od države. Libertarijanci poput Rogera Vera došli su u Bitcoin zbog aktivnog anti-institucionalnog stava, i mogućnosti koju je nova tehnologija obećavala. Wences Casares, briljantni i dobro povezani serijski poduzetnik, bio je također dio drugog Bitcoin hype ciklusa te je širio riječ o Bitcoinu među najprominentnijim tehnolozima i ulagačima u Silicijskoj Dolini.

250 USD – 1100 USD (4. mjesec 2013. – 12. mjesec 2013.): Treći hype ciklus doživio je ulazak ranih generalnih i institucionalnih ulagača koji su bili voljni uložiti trud i riskirati kroz užasno komplicirane kanale likvidnosti kako bi kupili bitcoine. Primaran izvor likvidnosti na tržištu za vrijeme ovog perioda bio je MtGox, mjenjačnica bazirana u Japanu, koju je vodio notorno nesposobni i beskrupulozni Mark Karpeles, koji je kasnije završio i u zatvoru zbog svoje uloge u kolapsu MtGoxa.

Valja primijetiti da je rast Bitcoinove cijene za vrijeme spomenuti hype ciklusa većinom povezano sa povećanjem likvidnosti i lakoćom sa kojom su ulagači mogli kupiti bitcoine. Za vrijeme prvog hype ciklusa, nisu postojale mjenjačnice; akvizicija bitcoina se odvijala primarno kroz rudarenje (mining) ili kroz izravnu razmjenu sa onima koju su već izrudarili bitcoine. Za vrijeme drugog hype ciklusa, pojavile su se rudimentarne mjenjačnice, no nabavljanje i osiguravanje bitcoina na ovim mjenjačnicama bilo je previše kompleksno za sve osim tehnološki najsposobnijih ulagača. Čak i za vrijeme trećeg hype ciklusa, ulagači koju su slali novac na MtGox kako bi kupili bitcoine su morali raditi kroz značajne prepreke. Banke nisu bile voljne imati posla sa mjenjačnicom, a oni posrednici koji su nudili usluge transfera bili su često nesposobni, kriminalni, ili oboje. Nadalje, mnogi koji su uspjeli poslati novac MtGoxu, u konačnici su morali prihvatiti gubitak svojih sredstava kada je mjenjačnica hakirana i kasnije zatvorena.

Tek nakon kolapsa MtGox mjenjačnice i dvogodišnje pauze u tržišnoj cijeni Bitcoina, razvili su se zreli i duboki izvori likvidnosti; primjeri poput reguliranih mjenjačnica kao što su GDAX i OTC brokeri kao Cumberland mining. Dok je četvrti hype ciklus započeo 2016. godine, bilo je relativno lako običnim ulagačima kupiti i osigurati bitcoine.

1100 USD – 19600 USD? (2014. –?):

U trenutku pisanja ovog teksta, tržište Bitcoina je prolazilo svoj četvrti veliki hype ciklus. Sudjelovanje u ovom hype ciklusu dominirala je ona skupina koju je Michael Casey opisao kao “rana većina” običnih i institucionalnih ulagača.

Kako su se izvori likvidnosti produbljivali i sazrijevali, veliki institucionalni ulagači sada imaju priliku sudjelovati kroz regulirana “futures” tržišta. Dostupnosti takvih tržišta stvara put ka kreaciji Bitcoin ETF-a (exchange traded fund) (fond na slobodnom tržištu), koji će onda pokrenuti “kasnu većinu” i “najsporije” u sljedećim hype ciklusima.

Premda je nemoguće predvidjeti točan efekt budućih hype ciklusa, razumno je očekivati da će najviša točka biti između 20.000 USD i 50.000 USD (2021. zenit je bio preko 69.000 USD). Znatno više od ovog raspona, i Bitcoin bi imao znatan postotak ukupne vijednosti zlata (zlato i Bitcoin bi imali jednaku tržišnu kapitalizaciju kada bi bitcoini vrijedili oko 380.000 USD u trenutku pisanja ovog teksta). Značajan postotak vrijednosti zlata dolazi od potražnje centralnih banaka, te je malo vjerojatno da će centralne banke ili suverene države sudjelovati u trenutnom hype ciklusu.

Ulazak suverenih država u Bitcoin

Bitcoinov zadnji Gartner hype ciklus će započeti kada ga suverene države počnu akumulirati kao dio svojih rezervi stranih valuta. Tržišna kapitalizacija Bitcoina je trenutno premala da bismo ga smatrali značajnim dodatkom rezervama većini zemalja. No, kako se interes u privatnom sektoru povećava i kapitalizacija Bitcoina se približi trilijunu dolara, postat će dovoljno likvidan za većinu država. Prva država koja službeno doda bitcoine u svoje rezerve će vjerojatno potaknuti stampedo ostalih da učine isto. Države koje su među prvima u usvajanju Bitcoina imat će najviše benefita u svojim knjigama ako Bitcoin u konačnici postane globalna valuta (global reserve currency). Nažalost, vjerojatno će države sa najjačom izvršnom vlasti - diktature poput Sjeverne Koreje - biti najbrže u akumulaciji bitcoina. Neodobravanje prema takvim državama i slaba izvršna tijela zapadnjačkih demokracija uzrokovat će sporost i kašnjenje u akumulaciji bitcoina za njihove vlastite rezerve.

Velika je ironija u tome što je SAD trenutno jedna od regulatorno najotvorenijih nacija prema Bitcoinu, dok su Kina i Rusija najzatvorenije. SAD riskira najviše, geopolitički, ako bi Bitcoin zamijenio dolar kao svjetska rezervna valuta. U 1960-ima, Charles de Gaulle je kritizirao “pretjeranu privilegiju” (“exorbitant privilege”) koju su SAD imale u međunarodnom monetarnom poretku, postavljenom kroz Bretton Woods dogovor 1944. godine. Ruska i kineska vlada još ne shvaćaju geo-strateške benefite Bitcoina kao rezervne valute, te se trenutno brinu o efektima koje bi mogao imati na njihova unutarnja tržišta. Kao de Gaulle u 1960-ima, koji je prijetio SAD-u povratkom na klasični standard zlata, Kinezi i Rusi će s vremenom uvidjeti korist u velikoj poziciji u Bitcoinu - spremištu vrijednosti bez pokrića ijedne vlade. Sa najvećom koncentracijom rudara Bitcoina u Kini (2017.), kineska vlada već ima znatnu potencijalnu prednost u stavljanju bitcoina u svoje rezerve.

SAD se ponosi svojim statusom nacije inovatora, sa Silicijskom dolinom kao krunom svoje ekonomije. Dosad, Silicijska dolina je dominirala konverzacijom usmjerenom prema regulaciji, i poziciji koju bi ona treba zauzeti prema Bitcoinu. No, bankovna industrija i federalna rezerva SAD-a (US Federal Reserve, Fed) napokon počinju uviđati egzistencijalnu prijetnju koju Bitcoin predstavlja za američku monetarnu politiku, postankom globalne rezervne valute. Wall Street Journal, jedan od medijskih glasova federalne reserve, izdao je komentar o Bitcoinu kao prijetnji monetarnoj politici SAD-a:

"Postoji još jedna opasnost, možda i ozbiljnija iz perspektive centralnih banaka i regulatora: bitcoin možda ne propadne. Ako je spekulativni žar u kriptovalutu samo prvi pokazatelj njezinog šireg korištenja kao alternative dolaru, Bitcoin će svakako ugroziti monopol centralnih banaka nad novcem."

U narednim godinama, možemo očekivati veliku borbu između poduzetnika i inovatora u Silicijskoj dolini, koji će pokušavati čuvati Bitcoin od državne kontrole s jedne strane, i bankovne industrije i centralnih banaka koje će učiniti sve što mogu da bi regulirale Bitcoin kako bi spriječile znatne promjene u svojoj industriji i moći izdavanja novca, s druge.

Prijelaz na medij razmjene

Monetarno dobro ne može postati opće prihvaćen medij razmjene (standardna ekonomska definicija za “novac”) prije nego je vrednovano od širokog spektra ljudi; jednostavno, dobro koje nije vrednovano neće biti prihvaćeno u razmjeni. Kroz proces generalnog rasta vrijednosti, i time postanka spremišta vrijednosti, monetarno dobro će brzo narasti u kupovnoj moći, i time stvoriti cijenu za korištenje u razmjeni. Samo kada ta cijena rizika mijenjanja spremišta vrijednosti padne dovoljno nisko, može dobro postati opće prihvaćen medij razmjene.

Preciznije, monetarno dobro će biti prikladno kao medij razmjene samo kada je suma cijene rizika i transakcijske cijene u razmjeni manja nego u trgovini bez tog dobra.

U društvu koje vrši robnu razmjenu, prijelaz spremišta vrijednosti u medij razmjene može se dogoditi čak i onda kada monetarno dobro raste u kupovnoj moći, zato što su transakcijski troškovi robne razmjene iznimno visoki. U razvijenoj ekonomiji, u kojoj su troškovi razmjene niski, moguće je za mladu i rapidno rastućnu tehnologiju spremišta vrijednosti, poput Bitcoina, da se koristi kao medij razmjene, doduše na ograničen način. Jedan primjer je ilegalno tržište droge, gdje su kupci voljni žrtvovati oportunu cijenu čuvanja bitcoina kako bi umanjili znatan rizik kupovine droge koristeći fiat novac.

Postoje međutim velike institucionalne barijere da novonastalo spremište vrijednosti postane sveopće prihvaćen medij razmjene u razvijenom društvu. Države koriste oporezivanje kao moćnu metodu zaštite svojeg suverenog novca protiv rivalskih monetarnih dobara. Ne samo da suvereni novac ima prednost konstantnog izvora potražnje, zato što je porez moguće platiti jedino u njemu, nego su i rivalska monetarna dobra oporezana pri svakoj razmjeni za vrijeme rastuće cijene. Ova metoda oporezivanja stvara znatan otpor korištenju spremišta vrijednosti kao medija razmjene.

Ovakvo sabotiranje tržišnih monetarnih dobara nije nepremostiva barijera za njihovo prihvaćanje kao općeg medija razmjene. Ako ljudi izgube vjeru u suvereni novac, njegova vrijednost može rapidno propasti kroz proces zvan hiperinflacija. Kada suvereni novac prolazi kroz hiperinflaciju, njegova vrijednost propadne prvo u usporedbi sa najlikvidnijim dobrima u društvu, kao što je zlato ili stabilna strana valuta (američki dolar npr.), ako su ona dostupna. Kada nema likvidnih dobara ili ih ima premalo, novac u hiperinflaciji kolabira u usporedbi sa stvarnim dobrima, kao što su nekretnine ili upotrebljiva roba. Arhetipska slika hiperinflacije je trgovina sa praznim policama - potrošači brzo bježe iz propadajuće vrijednosti novca svoje nacije.

Nakon dovoljno vremena, kada je vjera potpuno uništena za vrijeme hiperinflacije, suvereni novac više nitko ne prihvaća, te se društvo može vratiti na robnu razmjenu, ili će doživjeti potpunu zamjenu monetarne jedinice za sredstvo razmjene. Primjer ovog procesa bila je zamjena zimbabveanskog dolara za američki dolar. Takva promjena suverenog novca za stranu valutu je dodatno otežana relativnom oskudnošću strane valute i odsustvom stranih bankarskih institucija koje pružaju likvidnost tržištu.

Sposobnost lakog prenošenja bitcoina preko granica i odsustvo potrebe za bankarskim sustavom čine Bitcoin idealnim monetarnim dobrom za one ljude koji pate pod hiperinflacijom. U nadolazećim godinama, kako fiat valute nastave svoj povijesni trend ka bezvrijednosti, Bitcoin će postati sve popularniji izbor za ušteđevine ljudi diljem svijeta. Kada je novac nacije napušten i zamijenjen Bitcoinom, Bitcoin će napraviti tranziciju iz spremišta vrijednosti u tom društvu u opće prihvaćeno sredstvo razmjene. Daniel Krawicz stvorio je termin “hiperbitcoinizacija” da bi opisao ovaj proces.

Učestala pogrešna shvaćanja

Većina ovog članka usredotočila se na monetarnu prirodu Bitcoina. Sa tim temeljima možemo adresirati neke od najčešćih nerazumijevanja u Bitcoinu.

Bitcoin je balon (bubble)

Bitcoin, kao sva tržišna monetarna dobra, posjeduje monetarnu premiju. Ona često rezultira uobičajenom kritikom da je Bitcoin samo “balon.” No, sva monetarna dobra imaju monetarnu premiju. Naprotiv, ta monetarna premija (cijena viša od one koju diktira potražnja za dobrom kao korisnim) je upravo karakteristična za sve oblike novca. Drugim riječima, novac je uvijek i svuda balon. Paradoksalno, monetarno dobro je istovremeno balon i ispod vrijednosti ukoliko je u ranijim stadijima općeg prihvaćanja kao novac.

Bitcoin je previše volatilan

Volatilnost cijene Bitcoina je funkcija njegovog nedavnog nastanka. U prvih nekoliko godina svojeg postojanja, Bitcoin se ponašao kao mala dionica, i svaki veliki kupac - kao npr. braća Winklevoss - mogao je uzrokovati veliki skok u njegovoj cijeni. No, kako su se prihvaćenost i likvidnost povećavali kroz godine, volatilnost Bitcoina je srazmjerno smanjila. Kada Bitcoin postigne tržišnu kapitalizaciju (vrijednost) zlata, imat će sličnu volatilnost kao i zlato. Kako Bitcoin nastavi rasti, njegova volatilnost će se smanjiti do razine koja ga čini prikladnim za široko korištenje kao medij razmjene. Kao što je prethodno rečeno, monetizacija Bitcoina se odvija u seriji Gartner hype ciklusa. Volatilnost je najniža za vrijeme vrhunaca i dolina unutar ciklusa. Svaki hype ciklus ima nižu volatilnost od prethodnih, zato što je likvidnost tržišta veća.

Cijene transakcija su previsoke

Novija kritika Bitcoin mreže je ta da ju je povećanje cijena prijenosa bitcoina učinilo neprikladnom za sustav plaćanja. No, rast u cijenama transakcija je zdrav i očekivan. One su nužne za plaćanje bitcoin minera (rudara), koji osiguravaju mrežu validacijom transakcija. Rudare se plaća kroz cijene transakcija ili kroz blok-nagrade, koje su inflacijska subvencija od trane trenutnih vlasnika bitcoina.

S obzirom na Bitcoinovu fiksnu proizvodnju (monetarna politika koja ga čini idealnim za spremanje vrijednosti), blok-nagrade će s vremenom nestati i mrežu će se u konačnici morati osiguravati kroz cijene transakcija. Mreža sa “niskim” cijenama transakcija je mreža sa slabom sigurnosti i osjetljiva na vanjsku intervenciju i cenzuru. Oni koji hvale niske cijene Bitcoinovih alternative zapravo niti ne znajući opisuju slabosti tih takozvanih “alt-coina.”

Površan temelj kritika Bitcoinovih “visokih” cijena transakcija je uvjerenje da bi Bitcoin trebao biti prvo sustav plaćanja, i drugo spremište vrijednosti. Kao što smo vidjeli kroz povijest novca, ovo uvjerenje je naopako. Samo onda kada Bitcoin postane duboko ukorijenjeno spremište novca može biti prikladan kao sredstvo razmjene. Nadalje, kada oportunitetni trošak razmjene bitcoina dođe na razinu koja ga čini prikladnim sredstvom razmjene, većina trgovine neće se odvijati na samoj Bitcoin mreži, nego na mrežama “drugog sloja” (second layer) koje će imati niže cijene transakcija. Takve mreže, poput Lightning mreže, služe kao moderna verzija zadužnica koje su korištene za prijenos vlasničkih papira zlata u 19. stoljeću. Banke su koristile zadužnice zato što je prijenos samog metala bio daleko skuplji. Za razliku od takvih zadužnica, Lightning mreža će omogućavati nisku cijenu prijenosa bitcoina bez potrebe za povjerenjem prema trećoj strani, poput banaka. Razvoj Lightning mreže je tehnološka inovacija od izuzetne važnosti u povijesti Bitcoina, i njezina vrijednost će postati očita u narednim godinama, kako je sve više ljudi bude razvijalo i koristilo.

Konkurencija

Pošto je Bitcoin softverski protokol otvorenog tipa (open-source), oduvijek je bilo moguće kopirati softver i imitirati mrežu. Kroz godine nastajali su mnogi imitatori, od identičnih kopija, kao Litecoin, do kompleksnijih varijanti kao što je Ethereum, koje obećavaju arbitrarno kompleksne ugovorne mehanizme koristeći decentralizirani računalni sustav. Česta kritika Bitcoinu od strane ulagača je ta da on ne može zadržati svoju vrijednost kada je vrlo lako stvoriti konkurente koji mogu lako i brzo u sebi imati najnovije inovacije i softverske funkcionalnosti.

Greška u ovom argumentu leži u manju takozvanog “mrežnog efekta” (network effect), koji postoji u prvoj i dominantnoj tehnologiji u nekom području. Mrežni efekt - velika vrijednost korištenja Bitcoina samo zato što je već dominantan - je važno svojstvo samo po sebi. Za svaku tehnologiju koja posjeduje mrežni efekt, to je daleko najvažnije svojstvo koje može imati.

Za Bitcoin, mrežni efekt uključuje likvidnost njegovog tržišta, broj ljudi koji ga posjeduju, i zajednicu programera koji održavaju i unaprjeđuju njegov softver i svjesnost u javnosti. Veliki ulagači, uključujući države, će uvijek prvo tražiti najlikvidnije tržište, kako bi mogli ući i izaći iz tržišta brzo, i bez utjecanja na cijenu. Programeri će se pridružiti dominantnoj programerskoj zajednici sa najboljim talentom, i time pojačati samu zajednicu. Svjesnost o brendu sama sebe pojačava, pošto se nadobudni konkurenti Bitcoina uvijek spominju u kontekstu Bitcoina kao takvog.

Raskrižje na putu (fork)

Trend koji je postao popularan 2017. godine nije bio samo imitacija Bitcoinovog softvera, nego kopiranje potpune povijesti njegovih prošlih transakcija (cijeli blockchain). Kopiranjem Bitcoinovog blockchaina do određene točke/bloka i odvajanjem sljedećih blokova ka novoj mreži, u procesu znanom kao “forking” (odvajanje), Bitcoinovi konkurenti su uspjeli riješiti problem distribuiranja svojeg tokena velikom broju korisnika.

Najznačajniji takav fork dogodio se 1. 8. 2017. godine, kada je nova mreža nazvana Bitcoin Cash (Bcash) stvorena. Vlasnik N količine bitcoina prije 1.8.2017. bi onda posjedovao N bitcoina i N BCash tokena. Mala, ali vrlo glasna zajednica Bcash proponenata je neumorno pokušavala prisvojiti Bitcoinov brend i ime, imenujući svoju novu mrežu Bitcoin Cast i pokušavajući uvjeriti nove pridošlice u Bitcoin da je Bcash “pravi” Bitcoin. Ti pokušaji su većinom propali, i taj neuspjeh se vidi u tržišnim kapitalizacijama dviju mreža. No, za nove ulagače, i dalje postoji rizik da bi konkurent mogao kopirati Bitcoin i njegov blockchain i tako uspjeti u preuzimanju tržišne kapitalizacije, te postati de facto Bitcoin.

Moguće je uočiti važno pravilo gledajući velike forkove u prošlosti Bitcoin i Ethereum mreža. Većina tržišne kapitalizacije odvijat će se na mreži koja zadrži najviši stupanj talenta i aktivnosti u zajednici programera. Premda se na Bitcoin može gledati kao na nov i mlad novac, on je također računalna mreža koja počiva na softveru, kojeg se pak treba održavati i poboljšavati. Kupovina tokena na mreži koja ima malo neiskusnih programera bilo bi kao kupovati kopiju Microsoft Windowsa na kojoj rade lošiji programeri. Jasno je vidljivo iz povijesti forkova koji su se odvili 2017. godine da su najbolji računalni i kriptografski stručnjaci posvećeni razvoju originalnog Bitcoina, a ne nekoj od rastućeg broja imitacija koje su se izrodile iz njega.

Stvarni rizici

Premda su uobičajene kritike upućene Bitconu od strane medija i ekonomske profesije krive i bazirane na netočnom shvaćanju novca, postoje pravi i značajni rizici kod ulaganja u Bitcoin. Bilo bi mudro za novog Bitcoin ulagača da shvati ove rizike prije potencijalnog ulaganja.

Rizik protokola

Bitcoin protokol i kriptografski sastavni dijelovi na kojima je sagrađen potencijalno imaju dosad nepronađenu grešku u svom dizajnu, ili mogu postati nesigurni razvojem kvantnih računala. Ako se pronađe greška u protokolu, ili neka nova metoda računarstva učini mogućim probijanje kriptografskih temelja Bitcoina, vjera u Bitcoin biti će znatno narušena. Rizik protokola bio je najviši u ranim godinama razvoja Bitcoina, kada je još uvijek bilo nejasno, čak i iskusnim kriptografima, je li Satoshi Nakamoto zaista riješio problem bizantskih generala (Byzantine Generals’ Problem). Brige oko ozbiljnih grešaka u Bitcoin protokolu nestale su kroz godine, no uzevši u obzir njegovu tehnološku prirodu, rizik protokola će uvijek ostati u Bitcoinu, makar i kao izuzetak.

Propadanje mjenjačnica

Time što je decentraliziran, Bitcoin je pokazao značajnu otpornost, suočen sa brojnim pokušajima raznih vlada da ga reguliraju ili unište. No, mjenjačnice koje trguju bitcoinima za fiat valute su centralizirani entiteti i podložne regulacijama i zatvaranju. Bez mjenjačnica i volje bankara da s njima posluju, proces monetizacije Bitcoina bio bi ozbiljno usporen, ako ne i potpuno zaustavljen. Iako postoje alternativni izvori likvidnosti za Bitcoin, poput “over-the-counter” brokera i decentraliziranih tržišta za kupovinu i prodaju bitcoina, kritičan proces otkrivanja i definiranja cijene se odvija na najlikvidnijim mjenjačnicama, koje su sve centralizirane.

Jedan od načina za umanjivanje rizika gašenja mjenjačnica je geografska arbitraža. Binance, jedna od velikih mjenjačnica iz Kine, preselila se u Japan nakon što joj je kineska vlada zabranila operiranje u Kini. Vlade su također oprezne kako ne bi ugušile novu industriju koja je potencijalno značajna kao i internet, i time predale nevjerojatnu konkurentnu vrijednost drugim nacijama.

Samo kroz koordinirano globalno ukidanje Bitcoin mjenjačnica bi proces monetizacije mogao biti zaustavljen. Trenutno smo u utrci; Bitcoin raste i postaje sve rašireniji, i doći će do trenutka kada bi potpuno ukidanje mjenjačnica postalo politički neizvedivo - kao i gašenje interneta. Mogućnost takvog ukidanja je još uvijek realna, i valja je uzeti u obzir pri ulaganju u Bitcoin. Kao što je gore objašnjeno, suverene vlade se polako bude i uviđaju prijetnju koju predstavlja neovisna digitalna valuta otporna na cenzuru, za njihovu monetarnu politiku. Otvoreno je pitanje hoće li išta poduzeti da odgovore ovoj prijetnji prije nego Bitcoin postane toliko utvrđen i raširen da politička akcija postane nemoćna i ne-efektivna.

Zamjenjivost

Otvorena i transparentna priroda Bitcoin blockchaina omogućava državama da proglase specifične bitcoine “okaljanima” zbog njihovog korištenja u određenim aktivnostima. Premda Bitcoin, na protokolarnoj razini, ne diskriminira transakcije na ikoji način, “okaljani” bitcoini bi mogli postati bezvrijedni ako bi ih regulacije proglasile ilegalnima i neprihvatljivima za mjenjačnice ili trgovce. Bitcoin bi tada izgubio jedno od kritičnih svojstava monetarnog dobra: zamjenjivost.

Da bi se ovaj problem riješio i umanjio, biti će potrebna poboljšanja na razini protokola kako bi se poboljšala privatnost transakcija. Premda postoji napredak u ovom smjeru, prvi put primjenjen u digitalnim valutama kao što su Monero i Zcash, potrebno je napraviti značajne tehnološke kompromise između efikasnosti i kompleksnosti Bitcoina i njegove privatnosti. Pitanje ostaje otvoreno je li moguće dodati nova svojstva privatnosti na Bitcoin, na način koji neće kompromitirati njegovu korisnost kao novca.

Zaključak

Bitcoin je novonastali novac koji je u procesu transformacije iz sakupljačkog dobra u spremište vrijednosti. Kao neovisno monetarno dobro, moguće je da će u budućnosti postati globalan novac, slično kao zlato za vrijeme 19. stoljeća. Prihvaćanje Bitcoina kao globalnog novca je upravo taj optimističan scenarij za Bitcoin, kojeg je artikulirao Satoshi Nakamoto još 2010. godine u email razmjeni sa Mikeom Hearnom:

"Ako zamisliš da se koristi u nekom dijelu svjetske trgovine, i da će postojati samo 21 milijun bitcoina za cijeli svijet, vrijednost po jedinici će biti znatno veća".

Ovaj scenarij je još snažnije definirao briljantni kriptograf Hal Finney, koji je ujedno primio i prve bitcoine od Nakamotoa, ubrzo nakon najave prvog funkcionalnog Bitcoin softvera:

"Zamislimo da Bitcoin bude uspješan i postane dominantan sustav plaćanja diljem svijeta. U tom slučaju će ukupna vrijednost valute biti jednaka ukupnoj vrijednosti svog bogatstva svijeta. Današnje procjene ukupnog svjetskog bogatska kućanstava koje sam pronašao borave negdje između 100 i 300 trilijuna dolara. Sa 20 milijuna bitcoina, svaki bi onda vrijedio oko 10 milijuna dolara."

Čak i da Bitcoin ne postane u cijelost globalan novac, nego da se samo natječe sa zlatom kao neovisno spremište vrijednosti, i dalje je masivno podcijenjen. Mapiranje tržišne kapitalizacije postojeće količine izrudarenog zlata (oko 8 trilijuna dolara) na maksimalnu dostupnost Bitcoina od 21 milijun, daje vrijednost od otprilike 380,000 dolara po bitcoinu. Kao što smo vidjeli u prethodnom tekstu, svojstva koja omogućavaju monetarnom dobru da bude prikladno spremište vrijednosti, čine Bitcoin superiornijim zlatu u svakom pogledu osim trajanja povijesti. No, kako vrijeme prolazi i Lindy efekt postane jači, dosadašnja povijest će prestati biti prednost zlata. Samim time, nije nerazumno očekivati da će Bitcoin narasti do, a možda i preko, ukupne cijene zlata na tržištvu do 2030. Opaska ovoj tezi je činjenica da veliki postotak vrijednosti zlata dolazi od toga što ga centralne banke čuvaju kao spremište vrijednosti. Da bi Bitcoin došao do te razine, određena količina suverenih država će trebati sudjelovati. Hoće li zapadnjačke demokracije sudjelovati u vlasništvu Bitcoina je nepoznato. Vjerojatnije je, nažalost, da će prve nacije u Bitcoin tržištu biti sitne diktature i kleptokracije.

Ako niti jedna država ne bude sudjelovala u Bitcoin tržištu, optimistična teza i dalje postoji. Kao nevisno spremište vrijednosti u rukama individualnih i institucionalnih ulagača, Bitcoin je i dalje vrlo rano u svojoj “krivulji prihvaćenosti” (adoption curve); tzv. “rana većina” ulaze na tržište sada, dok će ostali ući tek nekoliko godina kasnije. Sa širim sudjelovanjem individualnih i institucionalnih ulagača, cijena po bitcoinu između 100,000 i 200,000 dolara je sasvim moguća.

Posjedovanje bitcoina je jedna od malobrojnih asimetričnih novčanih strategija dostupnih svakome na svijetu. Poput “call” opcija, negativan rizik ulagača je ograničen na 1x, dok potencijalna dobit i dalje iznosi 100x ili više. Bitcoin je prvi istinski globalan balon čija je veličina ograničena samo potražnjom i željom građana svijeta da zaštite svoju ušteđevinu od raznovrsnih ekonomskih malverzacija vlade. Bitcoin je ustao kao feniks iz pepela globalne financijske krize 2008. godine - katastrofe kojoj su prethodile odluke centralnih banaka poput američke Federalne rezerve (Federal Reserve).

Onkraj samo financijske teze za Bitcoin, njegov rast i uspjeh kao neovisno spremište vrijednosti imat će duboke geopolitičke posljedice. Globalna, ne-inflacijska valuta će prisiliti suverene države da promjene svoje primarne mehanizme financiranja od inflacije u izravno oporezivanje; koje je daleko manje politički popularno. Države će se smanjivati proporcionalno političkoj boli koju im nanese oporezivanje kao jedini način financiranja. Nadalje, globalna trgovina vršiti će se na način koji zadovoljava aspiraciju Charlesa de Gaullea, da nijedna nacija ne bi smjela imati privilegiju nad ikojom drugom:

"Smatramo da je potrebno da se uspostavi međunarodna trgovina, kao što je bio slučaj prije velikih nesreća koje su zadesile svijet, na neosporivoj monetarnoj bazi, koja ne nosi na sebi oznaku ijedne države."

Za 50 godina, ta monetarna baza biti će Bitcoin.

It's wild. I just proved I can build #nostr 'wallet' where I can store the encrypted tokens in a Germany relay and make the lightning payment out of a Singapore mint. All using a #nsec that never leaves my machine. https://primal.net/e/note15l02rf4r474ck04mlrxxfagyl0z6t04ltsugf9dtph4xxhzfnd4sqpk74n

I’ve proven to myself that a #nostr wallet can exist across time and space, independently of any one app, server or custodian. The only thing which controls the ‘wallet’ is the generation and control of an #nsec which is free to exist within or flee any jurisdiction.

In my mind, this lays to rest the notion that a wallet needs to be an app, service, or anything that can be captured commercially or by the state. https://primal.net/e/note13nwsh852x9tfex2jade6vwymhhct8zussxr4zwy7uag24hjc9stq0xsxaf

I am thinking about coining the term “nsac” to refer to a wallet-like thing that can exist on #nostr holding your valuable things, such as ecash tokens. I have already implemented a prototype #cashu ecash wallet which looks to be promising.

So you would have:

npub - your identity

nsec - your private key

nsac - your valuables

Your #nsac could be the same as your #nsec but better case is to generate as many #nsacs as required.

Happy to hear feedback!

For reference, what a ‘sac’ is in the biological sense:

A sac is a biological term referring to a pouch or cavity in an organism that is typically enclosed and may contain fluid, air, or other substances. Sacs can serve various functions depending on their location and role in the body, such as protecting a developing embryo, facilitating the exchange of gases in the lungs, or reducing friction between moving parts in joints

The PH value of a swimming pool is one of the important indicators for measuring the quality of swimming pool water. Its importance is mainly reflected in the following aspects:

Affecting human comfort The pH of water that the human body is most adapted to is neutral. Inappropriate pH of swimming pool water will irritate human skin, eyes and mucous membranes, causing discomfort. For example, when the pH value is high or low, it may irritate the swimmer's skin, eyes, etc., causing discomfort such as itchy skin, red and swollen eyes, and sticky hair, affecting the swimmer's physical health and swimming experience. Affecting the disinfection effect of swimming pools Affecting the activity of chlorine disinfectants Swimming pools are usually disinfected with chlorine-containing disinfectants. Different pH values will cause differences in the activity and disinfection ability of chlorine. When the pH value in swimming pool water is greater than 8.0, the activity of chlorine disinfectants in water will be significantly reduced, that is, the disinfection ability will be reduced, which will affect the algae removal and sterilization effects, resulting in the proliferation of green algae in swimming pool water. When the pH value is less than 7.0, the activity of the disinfectant in the swimming pool will be relatively high, the residual chlorine in the swimming pool will dissipate faster, and the disinfection durability of the swimming pool disinfectant will be greatly weakened. Under the condition of pH about 7.5, there is a relatively good disinfection effect and the duration of the drug effect is relatively long.

Influence on the existence form of residual chlorine Depending on the pH value, free chlorine may be chlorine gas (Cl₂), chlorophyll acid (HClO) or hypocrite ion (ClO⁻) dissolved in water. The disinfection effect of HClO is about 100 times stronger than that of ClO⁻. When the pH value is about 7.5, both chlorophyll acid and hypocrite ion exist, and the proportion is roughly equal, which can ensure a better disinfection effect.

Corrosion to swimming pool facilities Pool water acidity or alkalinity will have a corrosive effect on swimming pool equipment. If the water is acidic, it will also corrode the accessories of the suction machine and affect the normal use of the equipment. If the pH value is unbalanced for a long time, the chemical disinfectants in the swimming pool will corrode the pool structure and swimming pool equipment, which will not only affect the appearance of the pool structure and equipment, but also shorten the service life of the swimming pool and increase the maintenance cost of the swimming pool in the later stage.

Impact on the containment of pool water The pH value in the swimming pool will change due to many external factors, such as rain, the use of swimming pool disinfectants, and alkaline chemicals. Maintaining a suitable pH value can make the pool water have better containment, more stably cope with the influence of these external factors, and maintain the relative stability of water quality.

In summary, the pH value of the swimming pool is of great significance to ensure the health and comfort of swimmers, ensure the disinfection effect, protect swimming pool facilities, and maintain the stability of pool water quality.

Your identity is important to you, right? While impersonation can be seen in some senses as a form of flattery, we all would prefer to be the only person capable of representing ourselves online, unless we intentionally delegate that privilege to someone else and maintain the ability to revoke it.

Amber does all of that for you in the context of #Nostr. It minimizes the possibility of your private key being compromized by acting as the only app with access to it, while all other Nostr apps send requests to Amber when they need something signed. This even allows you to give someone temporary authority to post as you without giving them your private key, and you retain the authority to revoke their permissions at any time.

nostr:npub1w4uswmv6lu9yel005l3qgheysmr7tk9uvwluddznju3nuxalevvs2d0jr5 has provided Android users with an incredibly powerful tool in Amber, and he continues to improve its functionality and ease of use. Indeed, there is not currently a comparative app available for iOS users. For the time being, this superpower is exclusive to Android.

Installation

Open up the Zapstore app that you installed in the previous stage of this tutorial series.

Very likely, Amber will be listed in the app collection section of the home page. If it is not, just search for "Amber" in the search bar.

Opening the app's page in the Zapstore shows that the release is signed by the developer. You can also see who has added this app to one of their collections and who has supported this app with sats by zapping the release.

Tap "Install" and you will be prompted to confirm you are sure you want to install Amber.

Helpfully, you are informed that several other users follow this developer on Nostr. If you have been on Nostr a while, you will likely recognize these gentlemen as other Nostr developers, one of them being the original creator of the protocol.

You can choose to never have Zapstore ask for confirmation again with apps developed by nostr:npub1w4uswmv6lu9yel005l3qgheysmr7tk9uvwluddznju3nuxalevvs2d0jr5, and since we have another of his apps to install later in this tutorial series, I recommend you toggle this on. Then tap on "Trust greenart7c3 and install app."

Just like when you installed the Zapstore from their GitHub, you will be prompted to allow the Zapstore to install apps, since Android considers it an "unknown source."

Once you toggle this on and use the back button to get back to the Zapstore, Amber will begin downloading and then present a prompt to install the app. Once installed, you will see a prompt that installation was a success and you can now open the app.

From here, how you proceed will depend on whether you need to set up a new Nostr identity or use Amber with an existing private key you already have set up. The next section will cover setting up a new Nostr identity with Amber. Skip to the section titled "Existing Nostrich" if you already have an nsec that you would like to use with Amber.

New Nostrich

Upon opening the application, you will be presented with the option to use an existing private key or create a new Nostr account. Nostr doesn't really have "accounts" in the traditional sense of the term. Accounts are a relic of permissioned systems. What you have on Nostr are keys, but Amber uses the "account" term because it is a more familiar concept, though it is technically inaccurate.

Choose "Create a new Nostr account" and you will be presented with a screen telling you that your Nostr account is ready. Yes, it was really that easy. No email, no real name, no date of birth, and no annoying capcha. Just "Create a new account" and you're done.

The app presents you with your public key. This is like an address that can be used to find your posts on Nostr. It is 100% unique to you, and no one else can post a note that lists this npub as the author, because they won't have the corresponding private key. You don't need to remember your npub, though. You'll be able to readily copy it from any Nostr app you use whenever you need it.

You will also be prompted to add a nickname. This is just for use within Amber, since you can set up multiple profiles within the app. You can use anything you want here, as it is just so you can tell which profile is which when switching between them in Amber.

Once you've set your nickname, tap on "Continue."

The next screen will ask you what Amber's default signing policy should be.

The default is to approve basic actions, referring to things that are common for Nostr clients to request a signature for, like following another user, liking a post, making a new post, or replying. If you are more concerned about what Amber might be signing for on your behalf, you can tell it to require manual approval for each app.

Once you've made your decision, tap "Finish." You will also be able to change this selection in the app settings at any time.

With this setup out of the way, you are now presented with the main "Applications" page of the app.

At the top, you have a notification encouraging you to create a backup. Let's get that taken care of now by tapping on the notification and skipping down to the heading titled "Backing Up Your Identity" in this tutorial.

Existing Nostrich

Upon opening the application, you will be presented with the option to use your private key or create a new Nostr account. Choose the former.

The next screen will require you to paste your private key.

You will need to obtain this from whatever Nostr app you used to create your profile, or any other Nostr app that you pasted your nsec into in the past. Typically you can find it in the app settings and there will be a section mentioning your keys where you can copy your nsec. For instance, in Primal go to Settings > Keys > Copy private key, and on Amethyst open the side panel by tapping on your profile picture in the top-left, then Backup Keys > Copy my secret key.

After pasting your nsec into Amber, tap "Next."

Amber will give you a couple options for a default signing policy. The default is to approve basic actions, referring to things that are common for Nostr clients to request a signature for, like following another user, liking a post, making a new post, or replying. If you are more concerned about what Amber might be signing for on your behalf, you can tell it to require manual approval for each app.

Once you've made your decision, tap "Finish." You will also be able to change this selection in the app settings at any time.

With this setup out of the way, you are now presented with the main "Applications" page of the app. You have nothing here yet, since you haven't used Amber to log into any Nostr apps, but this will be where all of the apps you have connected with Amber will be listed, in the order of the most recently used at the top.

Before we go and use Amber to log into an app, though, let's make sure we've created a backup of our private key. You pasted your nsec into Amber, so you could just save that somewhere safe, but Amber gives you a few other options as well. To find them, you'll need to tap the cog icon at the bottom of the screen to access the settings, then select "Backup Keys."

Backing Up Your Identity

You'll notice that Amber has a few different options for backing up your private key that it can generate.

First, it can give you seed words, just like a Bitcoin seed. If you choose that option, you'll be presented with 12 words you can record somewhere safe. To recover your Nostr private key, you just have to type those words into a compatible application, such as Amber.

The next option is to just copy the secret/private key in its standard form as an "nsec." This is the least secure way to store it, but is also the most convenient, since it is simple to paste into another signer application. If you want to be able to log in on a desktop web app, the browser extension Nostr signers won't necessarily support entering your 12 word seed phrase, but they absolutely will support pasting in your nsec.

You can also display a QR code of your private key. This can be scanned by Amber signer on another device for easily transferring your private key to other devices you want to use it on. Say you have an Android tablet in addition to your phone, for instance. Just make sure you only use this function where you can be certain that no one will be able to get a photograph of that QR code. Once someone else has your nsec, there is no way to recover it. You have to start all over on Nostr. Not a big deal at this point in your journey if you just created a Nostr account, but if you have been using Nostr for a while and have built up a decent amount of reputation, it could be much more costly to start over again.

The next options are a bit more secure, because they require a password that will be used to encrypt your private key. This has some distinct advantages, and a couple disadvantages to be aware of. Using a password to encrypt your private key will give you what is called an ncryptsec, and if this is leaked somehow, whoever has it will not necessarily have access to post as you on Nostr, the way they would if your nsec had been leaked. At least, not so long as they don't also have your password. This means you can store your ncryptsec in multiple locations without much fear that it will be compromised, so long as the password you used to encrypt it was a strong and unique one, and it isn't stored in the same location. Some Nostr apps support an ncryptsec for login directly, meaning that you have the option to paste in your ncryptsec and then just log in with the password you used to encrypt it from there on out. However, now you will need to keep track of both your ncryptsec and your password, storing both of them safely and separately. Additionally, most Nostr clients and signer applications do not support using an ncryptsec, so you will need to convert it back to a standard nsec (or copy the nsec from Amber) to use those apps.

The QR option using an ncryptsec is actually quite useful, though, and I would go this route when trying to set up Amber on additional devices, since anyone possibly getting a picture of the QR code is still not going to be able to do anything with it, unless they also get the password you used to encrypt it.

All of the above options will require you to enter the PIN you set up for your device, or biometric authentication, just as an additional precaution before displaying your private key to you.

As for what "store it in a safe place" looks like, I highly recommend a self-hosted password manager, such as Vaultwarden+Bitwarden or KeePass. If you really want to get wild, you can store it on a hardware signing device, or on a steel seed plate.

Additional Settings

Amber has some additional settings you may want to take advantage of. First off, if you don't want just anyone who has access to your phone to be able to approve signing requests, you can go into the Security settings add a PIN or enable biometrics for signing requests. If you enable the PIN, it will be separate from the PIN you use to access your phone, so you can let someone else use your phone, like your child who is always begging to play a mobile game you have installed, without worrying that they might have access to your Nostr key to post on Amethyst.

Amber also has some relay settings. First are the "Active relays" which are used for signing requests sent to Amber remotely from Nostr web apps. This is what enables you to use Amber on your phone to log into Nostr applications on your desktop web browser, such as Jumble.social, Coracle.social, or Nostrudel.ninja, eliminating your need to use any other application to store your nsec whatsoever. You can leave this relay as the default, or you can add other relays you want to use for signing requests. Just be aware, not all relays will accept the notes that are used for Nostr signing requests, so make sure that the relay you want to use does so. In fact, Amber will make sure of this for you when you type in the relay address.

The next type of relays that you can configure in Amber are the "Default profile relays." These are used for reading your profile information. If you already had a Nostr identity that you imported to Amber, you probably noticed it loaded your profile picture and display name, setting the latter as your nickname in Amber. These relays are where Amber got that information from. The defaults are relay.nostr.band and purplepag.es. The reason for this is because they are aggregators that look for Nostr profiles that have been saved to other relays on the network and pull them in. Therefore, no matter what other relay you may save your profile to, Amber will likely be able to find it on one of those two relays as well. If you have a relay you know you will be saving your Nostr profiles to, you may want to add it to this list.

You can also set up Amber to be paired with Orbot for signing over Tor using relays that are only accessible via the Tor network. That is an advanced feature, though, and well beyond the scope of this tutorial.

Finally, you can update the default signing policy. Maybe after using Amber for a while, you've decided that the choice you made before was too strict or too lenient. You can change it to suit your needs.

Zapstore Login

Now that you are all set up with Amber, let's get you signed into your first Nostr app by going back to the Zapstore.

From the app's home screen, tap on the user icon in the upper left of the screen. This will open a side panel with not much on it except the option to "sign in." Go ahead and tap on it.

You will be presented with the option to either sign in with Amber, or to paste your npub. However, if you do the latter, you will only have read access, meaning you cannot zap any of the app releases. There are other features planned for the Zapstore that may also require you to be signed in with write access, so go ahead and choose to log in with Amber.

Your phone should automatically switch to Amber to approve the sign-in request.

You can choose to only approve basic actions for Zapstore, require it to manually approve every time, or you can tell it that you "fully trust this application." Only choose the latter option with apps you have used for a while and they have never asked you to sign for anything suspicious. For the time being, I suggest you use the "Approve basic actions" option and tap "Grant Permissions."

Your phone will switch back to the Zapstore and will show that you are now signed in. Congratulations! From here on out, logging into most Nostr applications will be as easy as tapping on "Log in with Amber" and approving the request.

If you set up a new profile, it will just show a truncated version of your npub rather than the nickname you set up earlier. That's fine. You'll have an opportunity to update your Nostr profile in the next tutorial in this series and ensure that it is spread far and wide in the network, so the Zapstore will easily find it.

That concludes the tutorial for Amber. While we have not covered using Amber to log into Nostr web apps, that is outside the scope of this series, and I will cover it in an upcoming tutorial regarding using Amber's remote signer options in detail.

Since you're already hanging out in the Zapstore, you may as well stick around, because we will be using it right out the gate in the next part of this series: Amethyst Installation and Setup. (Coming Soon)

Quando adolescente eu acreditava na coerência da teoria de "amor líquido" do polonês, sociólogo, Zygmunt Bauman, apresentada no livro "Amor Líquido: Sobre a Fragilidade dos Laços Humanos", qual no meu amadurecimento em estudos, sejam eles no meio acadêmico ou fora, percebo como uma das formas mais rasas de explicar as mudanças e transformações dos padrões de relações sócio-afetivas dos humanos. A seguir colocar-me-ei na minha juventude não tanto recente, direi então que nós, se adolescentes e conservadores, ou mesmo jovens adultos mais conservadores, costumamos levar como dogma uma óptica decadentista generalizada de todos os avanços de eras dos homens, universalizamos por nos ser comum a indistinção entre humanidade e humanidades, ou mesmo "humanity" e "humankind" ("humanidade" como espécime e "humanidade" como um universal), compreendemos toda "essas" como "essa" e indistinguimos as sociedades para com os homens, ou seja, a incapacidade de definir os seres dentro de suas respectivas singularidades e especificidades nos leva ao decadentismo generalista (a crença de que de forma geral, e universal, a "civilização universal" decai moralmente, éticamente, materialmente e espiritualmente), que aparente à nós determinadas mudanças nas relações humanas quanto ao caráter sócio-afetivo, por falta de profundidade e critérios ainda sobre questões alinhadas aos métodos e coerências, ou incoerências, lógicas, nós se jovens e conservadores somos levados ao engodo de concordar com a teoria do amor líquido de Bauman, que devo cá explicar de antemão: trata ela, a teoria, o padrão de "amor" dos tempos presentes como frágil, de prazo (curto e médio) e diferente em grau comparativamente ao amor comum das eras passadas.

Aos jovens mais progressistas opera uma compreensão dialética sobre as eras dos homens nos seu tempo presente, na qual ao tempo que o ser progride ele também regride simultaneamente, ou seja, a medida que aparecem contradições advindas de transformações materiais da realidade humana o ser supera essas contradições e progride em meio as transformações, ainda fazendo parte da lógica dessa indissociavelmente, assim constantemente progredindo e regredindo, havendo para esses dois vetores de distinção: o primeiro é o que releva questões espirituais como ao caráter do pensamento "new age", o segundo ignora essas questões por negar a existência da alma, seguem ao materialismo. Cedem em crer na teoria baumaninana como dogma, pois não encontram outros meios para explicar as transformações da sociedade na esfera sócio-afetiva sem que haja confrontamento direto com determinadas premissas assim pertinemente presentes, ou por não conciliarem com análises relativamente superiores, como a de Anthony Giddens sobre a "relação pura" em "A Transformação da Intimidade" e de François de Singly apresentada em "Sociologie du Couple".

Há um problema quando uma teoria deixa de assim ser para vir a tornar-se mais um elemento desconexo da ciência, agora dentro da cultura pop, se assim podemos dizer, ou da cultura de massa, ou se preferirem mesmo "anticultura", esse problema é a sua deformização teórica, tornando-se essa rasa para sua palatabilidade massiva, somada a incapacidade de partes da sociedade civil em compreender as falhas daquilo que já foi massificado. Tive surpresa ao entender que muitos outros compartilham da mesma opinião, a exemplo, possuo um amigo na faculdade, marxista, que ao falarmos sobre nossos projetos de pesquisa, citou ele o projeto de um de nossos colegas, no qual esse referido um de nossos colegas faria seu projeto com base na teoria do amor líquido de Bauman, então alí demos risada disso, ora, para nós a teoria baumaniana é furada, passamos a falar sobre Bauman e o motivo pelo qual não gostávamos, lá fiquei até surpreso em saber que mais gente além de mim não gostava da teoria de Bauman, pois ao que eu via na internet era rede de enaltecimentos à figura e à sua teoria, tal como fosse uma revelação partindo de alguma divindade da Idade do Bronze. Pouco tempo depois tive em aula de teoria política uma citação de Bauman partindo do professor que ministrava a disciplina, no entanto, ao citar o nome de Bauman o mesmo fez uma feição na qual aparentava segurar risada, provavelmente ele também não levava Bauman à sério. Não devo negar que todas as vezes que vejo o sociólogo sendo citado em alguma nota no X, no Instagram ou qualquer outra rede social, tal como fosse um referencial teórico bom, sinto uma vergonha alheia pois alí tenho uma impressão de que a pessoa não leu Bauman e usa o referencial teórico como um fato já assim provado e comprovado.

Há pontos positivos na teoria baumaniana, como a capacidade de perceber o problema e correlacioná-lo à modernidade, assim como sucitar a influência do que há de material no fenômeno, porém os erros são pertinentes: o primeiro problema é de categoria. Não há, por parte de Bauman noção alguma entre as dissociações dos amores, não há atenção sobre o amor como estrutura ou ele como um sentimento, todo ele é compreendido uniformemente como "amor", partindo do pressuposto que todas as relações, todas elas, são firmadas com base no amor. Essa crença tem uma origem: Hegel. Nos Escritos Teológicos Hegel partia da crença que o amor ligava os seres relacionalmente como uma força de superação e alienação, mas há de compreendermos que esse Friedrich Hegel é o jovem ainda pouco maduro em suas ideias e seu sistema de pensamento, mais a frente, em "Fenomenologia do Espírito e na Filosofia do Direito", Hegel compreende a institucionalidade do direito no amor e a institucionalização dessa força, assim aproxima-se da realidade a respeito da inserção do amor nas esferas práticas do humano, porém essa ideia, apesar de imperfeita, pois ao que sabemos não é o amor que consolida a relação, mas sim a Verdade (Alétheia), conforme apontado por Heidegger em "Ser e Tempo", essa ideia do amor como a fundamento das relações humanas influenciou, e até hoje influencia, qualquer análise sobre as relações humanas fora da esfera materialista, fora dessa pois, melhormente explicado em exemplo, os marxistas (em exemplo), assim como Marx, consideram como base primordial das relações as condições materiais.

Por certo, não é de todo amor a base para a solidificação, ora, erram aqueles que creem que somente essa força, assim apontada por Hegel, constituiam todos os relacionamentos formais como pilares fundamentais, pois em prática as famílias eram até a fiduciarização dessas, por mais paradoxal que seja, compreendidas melhor como instituições orgânicas de caráter legal do que conluios de afetividades. A família outrora tinha consigo aparelhos de hierarquia bem estabelicidos, quais prezavam pela ordem interna e externa, que acima dessa instituição estava somente a Igreja (outra instituição), com sua fiduciarização [da família] após o movimento tomado pelos Estados nacionais em aplicação do casamento civil mudou-se a lógica das partes que a compõe, findou-se o princípio da subsidiariedade (não intervenção de determinadas instituições nas decisões quais podem ser exercidas em resuluções de problemas nas competências de quaisquer instituições), foi-se então, contudo, também a autoridade, e nisso revela-se um outro problema não apontado na teoria de Bauman: qual o padrão do amor "sólido"? Pois, ora, sociedades tradicionais não abdicavam do relevar dos amores para tornar seus filhos em ativos nas práticas de trocas (dádivas)? É notório que esse padrão se dissocia do padrão de sentimento apontado por Bauman, encontramos esse fato em estudo nos trabalhos "Ensaio Sobre a Dádiva", do Marcel Mauss, e "As Estruturas Elementares do Parentesco", do Claude Levi-Strauss, quais expõem que nas sociedades "sólidas", tradicionais, relevava-se mais questões institucionais que as sentimentais para a formação de laços (teoria da aliança). Muitas das relações passadas não eram baseadas no amor, não significando assim que as de hoje, em oposição, sejam, mas que permanecem-se semelhantes em base, diferentemente em grau e forma.

Ora, ainda existem casamentos motivados pela política, pelo status, pelo prestígio, pelos bens, pelo poder, pela influência familiar e assim sucetivamente, tal como no passado, ocorre que essa prática tornou-se oculta, não mais explícita e aparente, devo dizer ainda que em partes, pois prepondera em nosso tempo uma epidemia de adultérios, fornicações, práticas lascivas e demais práticas libertinosas explicitamente, em contraposição às práticas ocultas em vergonhas de sociedades sem declínio moral e espiritual, o que nos leva a questionar o método comparativo em dicotomia temporal "presente x passado" aplicado por Bauman, no qual segue-se da seguinte forma:

                     Transformação
Passado = *sólido* | Presente = *líquido*

Categorias
Padrão de amor: tradicional (*sólido*)
                            moderno (*líquido*)

*Sólido* = estável, prazo (médio-grande), profundo, determinado.
*Líquido* = instável, prazo (curto-médio), raso, indeterminado.

O que penso é: Zygmunt Bauman buscou uma explicação material e laical para desviar ao fato de que há uma notória correlação entre espiritualização da sociedade, se voltada à Verdade, com a estabilidade das instituições, o que é já reduzido à moral religiosa, somente, não à mística, como por pensadores da linha de Tocqueville, ou em abordagens também mais laical (positivista) porém ainda relevantes, como Émile Durkheim em "As Formas Elementares da Vida Religiosa" e Max Weber em "A Ética Protestante e o Espírito do Capitalismo", contrapondo uma abordage mais voltada, de fato, a espiritualidade, como Christopher Dawnson, que defende essa teoria em "Religião e o Surgimento da Cultura Ocidental", e Eric Voegelin, principalmente nas obras "A Nova Ciência da Política" e "Ordem e História".

Encerrrando, minha cosmovisão é a católica, o sistema de crença e religião qual sigo é do Deus que se fez homem por amor aos seus filhos, não posso negar ou mesmo omitir o fato de que, por trás de toda a minha crítica estão meus pensamentos e minhas convicções alinhadas àquilo que mais tenho amor em toda minha vida: a Verdade, e a Verdade é Deus, pois Cristo é a Verdade, o Caminho e a Vida, ninguém vai ao Pai se não por Ele, e pois bem, seria incoerência de minha parte não relevar o fato de crença como um dos motivos pelos quais eu rejeito a teoria do amor líquido de Zygmunt Bauman, pois os amores são todos eles praticados por formas, existem por diferentes formas e assim são desde sua tradicionalidade até o predomínio das distorções de declínio espiritual das eras presentes (e também antigas pré-Era Axial), estão esses preservados pelo alinhamento à verdade, assim são indistorcíveis, imutáveis, ou seja, amor é amor, não releva-se o falso amor como um, simplesmente não o é, assim o interesse, a sanha por bens, o egoísmo e a egolatria ("cupiditas", para Santo Agostinho de Hipona, em oposição ao que o santo e filósofo trata por "caritas") não são formas do amor, são autoenganos, não bons, se não são bons logo não são de Deus, ora, se Deus é amor, se ele nos ama, determino como amor (e suas formas) o que está de acordo com a Verdade. Aprofundando, a Teologia do Corpo, do Papa São João Paulo II, rejeita a "liquidez" apresentada por Bauman, pois o amor é, em suma, sacríficio, parte da entrega total de si ao próximo, e se não há logo não é amor. A Teologia do Corpo rejeita não os fundamentos de mentira no "líquido", mas também no "sólido", pois a tradicionalidade não é sinônimo de bom e pleno acordo com o amor que Deus pede de nós, não são as coerções, as violências, as imposições e demais vontades em oposição às de Deus que determinam os amores -- fatos em oposição ao ideário romanticizado. Claro, nem todas as coerções são por si inválidas do amor, ou mesmo as escolhas em trocas racionalizadas, a exemplo do autruísmo em vista da chance da família ter êxito e sucesso, ou seja, pelo bem dos próximos haver a necessidade de submissão a, em exemplo, um casamento forjado, ou algo do gênero, reconhece-se o amor no ato se feito por bem da família, porém o amor incutido, nesse caso, explicita o caráter sacrificial, no qual uma vontade e um amor genuinamente potencial em prazeres e alegrias são anulados, ou seja, mesmo nesse modelo tradicional na "solidez" há possibilidade do amor, não nas formas romanticizadas em critérios, como "estabilidade" e "durabilidade", mas no caráter do sacríficio exercido. Conforme nos ensina São Tomás de Aquino, o amor não é uma "força", tal como ensina Hegel, mas sim uma virtude teologal conforme na "Suma Teológica" (II-II Q. 26-28), não devemos reduzir o amor e os amores em análises simplórias (não simples) de falsa complexidade extraídas em métodos questionáveis e pouco competentes à real diensão de crise espiritual das eras, por esse motivo não concordo com a teoria do amor líquido de Zygmunt Bauman.

Nemzetközi nukleáris energetikai hírek

Új amerikai kis moduláris reaktor engedélykérelem

A Tennessee Valley Authority (TVA) benyújtotta az Egyesült Államok Nukleáris Szabályozó Hatóságához (NRC) az engedélykérelmet egy GE Vernova Hitachi Nuclear Energy BWRX-300 kis moduláris reaktor (SMR) megépítésére a Clinch River telephelyen. Ez jelentős lépés az új, fejlett nukleáris technológiák bevezetésében az Egyesült Államokban, és jól mutatja, hogy az SMR-ek egyre fontosabb, rugalmas és skálázható tisztaenergia-megoldássá válnak[world-nuclear-news.org].

Amerikai elnöki rendeletek a nukleáris bővítés felgyorsítására

Donald Trump amerikai elnök négy elnöki rendeletet írt alá, amelyek célja a reaktorengedélyezési folyamatok gyorsítása, a hazai urántermelés növelése és a fejlett nukleáris technológiák bevezetésének felgyorsítása. Az új irányelvek ambiciózus célokat tűznek ki, például az amerikai nukleáris kapacitás megnégyszerezését 2050-re, az NRC számára az engedélyezési idő 18 hónapra csökkentését, valamint szövetségi területek kijelölését új nukleáris létesítmények számára. Ezeket a rendeleteket az „amerikai nukleáris reneszánsz” alapjának szánják, különös hangsúlyt fektetve az AI-ipar energiaigényeinek kielégítésére és a hazai gyártás újjáélesztésére[nucnet.org].

Iparági optimizmus és globális befektetési trendek

Az iparági vezetők egészséges és optimista kilátásokról számolnak be a nukleáris energia terén, kiemelve olyan aktív projekteket, mint a TerraPower Wyomingban, az X-energy és a Dow együttműködése, valamint a Westinghouse tevékenysége Lengyelországban. Különösen nagy az érdeklődés a magánbefektetések iránt a magas dúsítású, alacsony dúsítású urán (HALEU) előállítása terén, illetve annak lehetősége iránt, hogy a Világbank elkezdjen nukleáris projekteket finanszírozni, ami szélesebb körű nemzetközi befektetéseket is elindíthat[ans.org].

Nemzetközi fejlemények és ellátási lánc felkészültsége

Számos ország halad előre a nukleáris fejlesztésekkel: - Kína tíz új reaktort hagyott jóvá. - India szabályozó hatósága engedélyezte egy új, négyblokkos telephely létesítését Rádzsasztánban. - Belgium konzultációt indított egy innovatív, ólom-hűtésű kis moduláris reaktor terveiről. - Brazília várhatóan Oroszországgal közösen fejleszt SMR-projektet. - Csehország új nukleáris szerződéseket köt, a külső politikai nyomás ellenére is.

A globális nukleáris ellátási láncot arra ösztönzik, hogy készüljön fel a gyors növekedésre, kiemelve a helyi és nemzetközi együttműködés fontosságát a növekvő igények kielégítésére[world-nuclear-news.org].

Úszó atomerőművek és tengeri innovációk

Az úszó atomerőművek továbbra is az innováció középpontjában állnak: - Oroszország Akademik Lomonosov nevű úszó atomerőműve elérte az első milliárd kilowattóra termelést. - Az Egyesült Királyságban a Core Power egy amerikai központú tengeri nukleáris programot fejleszt, melynek célja úszó reaktorok telepítése amerikai kikötőkben a 2030-as évek közepére. - A dán Seaborg Technologies (új nevén Saltfoss Energy) kompakt olvadt só reaktor technológián dolgozik, amelyet szintén a 2030-as évekre terveznek bevezetni. - A Westinghouse és a Core Power együttműködik egy úszó atomerőmű fejlesztésén az eVinci mikroreaktorral[world-nuclear-news.org].

Érintettek bevonása és társadalmi bizalom

A Nemzetközi Atomenergia-ügynökség (IAEA) kiemeli az érintettek bevonásának fontosságát a nukleáris energia jövője szempontjából. Folyamatban lévő konferenciáján olyan témákat tárgyalnak, mint a nukleáris energia szerepe az ipari dekarbonizációban, a nyilvános meghallgatások értéke a projektek átláthatósága érdekében, valamint a társadalmi bizalom és a szabályozói megfelelés legjobb gyakorlatai, különösen az új technológiák, például az SMR-ek bevezetése során[iaea.org].

Star Wars is often viewed as a myth of rebellion, freedom, and resistance to tyranny. The iconography—scrappy rebels, totalitarian stormtroopers, lone smugglers—suggests a deep anti-authoritarian ethos. Yet, beneath the surface, the narrative arc of Star Wars consistently affirms the necessity, even sanctity, of central authority. This blog entry introduces the question: Is Star Wars fundamentally a celebration of statism?

---

Rebellion as Restoration, Not Revolution

The Rebel Alliance’s mission is not to dismantle centralized power, but to restore the Galactic Republic—a bureaucratic, centrally governed institution. Characters like Mon Mothma and Bail Organa are high-ranking senators, not populist revolutionaries. The goal is to remove the corrupt Empire and reinstall a previous central authority, presumed to be just.

• Rebels are loyalists to a prior state structure.
• Power is not questioned, only who wields it.

---

Jedi as Centralized Moral Elites

The Jedi, often idealized as protectors of peace, are unelected, extra-legal enforcers of moral and military order. Their authority stems from esoteric metaphysical abilities rather than democratic legitimacy.

• They answer only to their internal Council.
• They are deployed by the Senate, but act independently of civil law.
• Their collapse is depicted as tragic not because they were unaccountable, but because they were betrayed.

This positions them as a theocratic elite, not spiritual anarchists.

---

Chaos and the Frontier: The Case of the Cantina

The Mos Eisley cantina, often viewed as a symbol of frontier freedom, reveals something darker. It is: - Lawless - Violent - Culturally fragmented

Conflict resolution occurs through murder, not mediation. Obi-Wan slices off a limb; Han shoots first—both without legal consequence. There is no evidence of property rights, dispute resolution, or voluntary order.

This is not libertarian pluralism—it’s moral entropy. The message: without centralized governance, barbarism reigns.

---

The Mythic Arc: Restoration of the Just State

Every trilogy in the saga returns to a single theme: the fall and redemption of legitimate authority.

1. Prequels: Republic collapses into tyranny.
2. Originals: Rebels fight to restore legitimate order.
3. Sequels: Weak governance leads to resurgence of authoritarianism; heroes must reestablish moral centralism.

The story is not anti-state—it’s anti-bad state. The solution is never decentralization; it’s the return of the right ruler or order.

---

Conclusion: The Hidden Statism of a Rebel Myth

Star Wars wears the costume of rebellion, but tells the story of centralized salvation. It: - Validates elite moral authority (Jedi) - Romanticizes restoration of fallen governments (Republic) - Portrays decentralized zones as corrupt and savage (outer rim worlds)

It is not an anarchist parable, nor a libertarian fable. It is a statist mythology, clothed in the spectacle of rebellion. Its core message is not that power should be abolished, but that power belongs to the virtuous few.

---

Question to Consider:
If the Star Wars universe consistently affirms the need for centralized moral and political authority, should we continue to see it as a myth of freedom? Or is it time to recognize it as a narrative of benevolent empire?

These days it can feel like the whole world is out of control. Government officials lie and break the law. People are selfish, act emotionally rather than logically, and push ideologies that are illogical and contrary to reality. Society is divided into groups and people are judged, not for their own character, but based on which group they are placed into. There are wars and rumors of wars. There are worries of pandemics and economic disasters. Depression, psychosis, and despair is rampant even among the youngest among us.

Hope For Believers

As much as things seem to be out of control, they are not out of God’s control. This is what the Bible predicted. No matter how bad things get in the world, those who have put their faith in Jesus, do not need to feel despair.

Why are you in despair, O my soul?\ And why have you become disturbed within me?\ Hope in God, for I shall again praise Him\ For the help of His presence.\ O my God, my soul is in despair within me;\ Therefore I remember You from the land of the Jordan\ And the peaks of Hermon, from Mount Mizar. (Psalm 42:5-6)

When we start to feel despair overcoming us, we need to remember what God has done and what He has promised. We need to praise God for what He has done, what He has promised, and what He will bring to completion. Things may be hard now, but God is still in control, and we know how the story will end. God triumphs. Good is rewarded. Evil is destroyed. We can stand on the foundation of hope because we know the ending. Even though things may be out of our personal control, they are always under God’s control.

The more fiercely the storm rages, the more we need to rest in Jesus and the more we need to put our hope in Him.

O love the Lord, all you His godly ones!\ The Lord preserves the faithful\ And fully recompenses the proud doer.\ **Be strong and let your heart take courage,\ All you who hope in the Lord. (Psalm 31:23-24) {emphasis mine}

We can take courage because God always acts for our long term good. Every hardship we experience here on earth will be recognized as a blessing that grew our faith and prepared us for heaven and God’s presence in eternity.

For I know the plans that I have for you,’ declares the Lord, ‘plans for welfare and not for calamity to give you a future and a hope. (Jeremiah 29:11)

Even the worst things that happen to us, due to the sins of others, have a good purpose in our lives. God is working good through us. Our hope isn’t an empty hope. It isn’t a “I really hope this happens.” It is a “I can hope in the guaranteed promises of God.”

For we do not want you to be unaware, brethren, of our affliction which came to us in Asia, that we were burdened excessively, beyond our strength, so that we despaired even of life; indeed, we had the sentence of death within ourselves so that we would not trust in ourselves, but in God who raises the dead; who delivered us from so great a peril of death, and will deliver us, He on whom we have set our hope. And He will yet deliver us, (2 Corinthians 1:8-10) {emphasis mine}

We may experience situations so bad that they seem hopeless, but with God, nothing is hopeless. The God who raises the dead can raise us out of any situation. The God who spoke the universe into existence can deliver us by a word.

The God of the Bible knows all and loves us completely. He looks at our situation through the lens of eternity. What seems best in the moment is not necessarily what is best for our eternity. Many times He delivers us through hardship rather than out of it. We just need to trust Him and put our hope in Him because He is good.

In the same way God, desiring even more to show to the heirs of the promise the unchangeableness of His purpose, interposed with an oath, so that by two unchangeable things in which it is impossible for God to lie, we who have taken refuge would have strong encouragement to take hold of the hope set before us. This hope we have as an anchor of the soul, a hope both sure and steadfast and one which enters within the veil, where Jesus has entered as a forerunner for us, having become a high priest forever according to the order of Melchizedek. (Hebrews 6:17-20) {emphasis mine}

Read that statement again. “This hope we have as an anchor of the soul, a hope both sure and steadfast.” Are you trusting Jesus as the “anchor of your soul?” Is your hope just a wish or is it a “sure and steadfast” hope based on the promises of God that you know will 100% come true?

And not only this, but we also exult in our tribulations, knowing that tribulation brings about perseverance; and perseverance, proven character; and proven character, hope; and hope does not disappoint, because the love of God has been poured out within our hearts through the Holy Spirit who was given to us. (Romans 5:3-5)

Isn’t it ironic that we need hope to persevere through tribulations, but that persevering through tribulation gives us character and hope? Our faith, trust, and hope grow through hardship. When things are easy, we almost always fall back on trusting in our own power rather than relying on God’s power. If we have put our faith in Jesus, there is no situation in which we should lose hope.

Now may the God of hope fill you with all joy and peace in believing, so that you will abound in hope by the power of the Holy Spirit. (Romans 15:13)

Is your joy and peace based on your circumstances or have you learned to have hope in God so you can experience joy and peace even in the trials?

Many people equate joy and happiness, but I think there is a key distinction. Happiness is a pleasant feeling that comes from pleasant circumstances. Joy is a similar feeling to happiness, but it comes from knowing God and His love. It is not tied to circumstances. When we have truly put our hope in God we can still have joy in and despite the most horrific circumstances.

Blessed be the God and Father of our Lord Jesus Christ, who according to His great mercy has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, to obtain an inheritance which is imperishable and undefiled and will not fade away, reserved in heaven for you, (1 Peter 1:3-4) {emphasis mine}

Just as Jesus told the Samaritan woman at the well that He provides living water that wells up inside, so that she need never thirst, in the same way believers have a living hope that wells up in times of need. Our hope is in the Creator of the universe and Savior of the world. No problem is too big for Him. No situation is a surprise to Him. No enemy is too powerful for Him. All of our problems are already solved. We just haven’t necessarily seen the solution yet.

My soul, wait in silence for God only,\ For my hope is from Him.\ He only is my rock and my salvation,\ My stronghold; I shall not be shaken.\ On God my salvation and my glory rest;\ The rock of my strength, my refuge is in God. (Psalm 62:5-7)

Despair For Unbelievers

Although believers never have reason to despair, the same is not true for those who have rejected the Savior, Jesus Christ. In these perilous times, they have a real reason for dread and despair.

Moreover, the Lord will scatter you among all peoples, from one end of the earth to the other end of the earth; and there you shall serve other gods, wood and stone, which you or your fathers have not known. Among those nations you shall find no rest, and there will be no resting place for the sole of your foot; but there the Lord will give you a trembling heart, failing of eyes, and despair of soul. So your life shall hang in doubt before you; and you will be in dread night and day, and shall have no assurance of your life. (Deuteronomy 64-66)

Those who reject the atoning sacrifice of Jesus do not get His protection. They do not get His help. They cannot rest in hope in Him.

Of course, the good news is that they can chose to turn their hearts to Him, confess their sins, and trust in Him up until their moment of death. Sadly many will continue to put off faith until it is too late. Many will choose evil over good and license over submission until God gives them over to their lusts.

And just as they did not see fit to acknowledge God any longer, God gave them over to a depraved mind, to do those things which are not proper, being filled with all unrighteousness, wickedness, greed, evil; full of envy, murder, strife, deceit, malice; they are gossips, slanderers, haters of God, insolent, arrogant, boastful, inventors of evil, disobedient to parents, without understanding, untrustworthy, unloving, unmerciful; and although they know the ordinance of God, that those who practice such things are worthy of death, they not only do the same, but also give hearty approval to those who practice them. (Romans 1:28-32)

If any of you have not yet put your trust in Jesus as Savior and Lord, do not wait. Turn away from evil. Submit to the will of Jesus. Trust Him to take away your sins and cover you with His righteousness.

If any of you know people who are in despair, share the gospel with them. Tell them about the greatness of God. Show them the hope that is within you.

Can Believers Despair?

Are there believers who despair? Yes. Should believers ever despair? Definitely not!

But we have this treasure in earthen vessels, so that the surpassing greatness of the power will be of God and not from ourselves; we are afflicted in every way, but not crushed; perplexed, but not despairing; persecuted, but not forsaken; struck down, but not destroyed; always carrying about in the body the dying of Jesus, so that the life of Jesus also may be manifested in our body. (2 Corinthians 4:7-10)

Jesus is always with believers in all situations guiding and protecting us. Those difficult situations that happen are for our good, even when we can’t see how it could be for good.

Job had more reasons to despair than almost anyone, yet he trusted in God. He didn’t know why he was being put through such loss, but his loss increased his faith in God and was a great example to people throughout history. I also love this cry of his heart.

“Oh that my words were written!\ Oh that they were inscribed in a book!” (Job 19:23)

He may or may not have seen even the partial fulfillment of this cry, but His words are written in the book of Job, in the Holy Scriptures read by Jews and Christians throughout the world and throughout history. Job’s first response to loss was an example to us all. After losing all ten children and all of his wealth, this was his response.

Then Job arose and tore his robe and shaved his head, and he fell to the ground and worshiped. (Job 1:20)

Yes, it is true that he had moments of despair where he cursed his birth, but he then returned to God in faith and hope. After a brief rebuke from God, Job submitted to God’s will.

“Behold, I am insignificant; what can I reply to You?\ I lay my hand on my mouth.\ Once I have spoken, and I will not answer;\ Even twice, and I will add nothing more.” (Job 40:4-5)

After his second rebuke from God, he fully submitted.

Then Job answered the Lord and said,

“I know that You can do all things,\ And that no purpose of Yours can be thwarted.\ ‘Who is this that hides counsel without knowledge?’\ *Therefore I have declared that which I did not understand,\ Things too wonderful for me, which I did not know.\ ‘Hear, now, and I will speak;\ I will ask You, and You instruct me*.’\ I have heard of You by the hearing of the ear;\ But now my eye sees You;\ Therefore I retract,\ And I repent in dust and ashes**.” (Job 42:1-6) {emphasis mine}

Job admitted that he did not understand what God was doing, but that God was right; God was good; and God was Lord. Job was able to have hope knowing that God was in control and working for good.

In the case of Job, he was later blessed with more kids, more wealth, and more respect than he had in the beginning. We won’t all see our blessings here on earth, but all believers will receive blessings from their trials.

May our glorious Savior and God fill you with faith and hope in God, His goodness, His power, and His plan. May we all submit to His good will even when we do not understand and even when every part of our earthly body is crying, “stop!” May God fill you with knowledge of Him, faith in Him, and hope in Him.

Know Your Customer is a regulation that requires companies of all sizes to verify the identity, suitability, and risks involved with maintaining a business relationship with a customer. Such procedures fit within the broader scope of anti-money laundering (AML) and counterterrorism financing (CTF) regulations.

Banks, exchanges, online business, mail providers, domain registrars... Everyone wants to know who you are before you can even opt for their service. Your personal information is flowing around the internet in the hands of "god-knows-who" and secured by "trust-me-bro military-grade encryption". Once your account is linked to your personal (and verified) identity, tracking you is just as easy as keeping logs on all these platforms.

Rights for Illusions

KYC processes aim to combat terrorist financing, money laundering, and other illicit activities. On the surface, KYC seems like a commendable initiative. I mean, who wouldn't want to halt terrorists and criminals in their tracks?

The logic behind KYC is: "If we mandate every financial service provider to identify their users, it becomes easier to pinpoint and apprehend the malicious actors."

However, terrorists and criminals are not precisely lining up to be identified. They're crafty. They may adopt false identities or find alternative strategies to continue their operations. Far from being outwitted, many times they're several steps ahead of regulations. Realistically, KYC might deter a small fraction – let's say about 1% ^1 – of these malefactors. Yet, the cost? All of us are saddled with the inconvenient process of identification just to use a service.

Under the rhetoric of "ensuring our safety", governments and institutions enact regulations that seem more out of a dystopian novel, gradually taking away our right to privacy.

To illustrate, consider a city where the mayor has rolled out facial recognition cameras in every nook and cranny. A band of criminals, intent on robbing a local store, rolls in with a stolen car, their faces obscured by masks and their bodies cloaked in all-black clothes. Once they've committed the crime and exited the city's boundaries, they switch vehicles and clothes out of the cameras' watchful eyes. The high-tech surveillance? It didn’t manage to identify or trace them. Yet, for every law-abiding citizen who merely wants to drive through the city or do some shopping, their movements and identities are constantly logged. The irony? This invasive tracking impacts all of us, just to catch the 1% ^1 of less-than-careful criminals.

KYC? Not you.

KYC creates barriers to participation in normal economic activity, to supposedly stop criminals. ^2

KYC puts barriers between many users and businesses. One of these comes from the fact that the process often requires multiple forms of identification, proof of address, and sometimes even financial records. For individuals in areas with poor record-keeping, non-recognized legal documents, or those who are unbanked, homeless or transient, obtaining these documents can be challenging, if not impossible.

For people who are not skilled with technology or just don't have access to it, there's also a barrier since KYC procedures are mostly online, leaving them inadvertently excluded.

Another barrier goes for the casual or one-time user, where they might not see the value in undergoing a rigorous KYC process, and these requirements can deter them from using the service altogether.

It also wipes some businesses out of the equation, since for smaller businesses, the costs associated with complying with KYC norms—from the actual process of gathering and submitting documents to potential delays in operations—can be prohibitive in economical and/or technical terms.

You're not welcome

Imagine a swanky new club in town with a strict "members only" sign. You hear the music, you see the lights, and you want in. You step up, ready to join, but suddenly there's a long list of criteria you must meet. After some time, you are finally checking all the boxes. But then the club rejects your membership with no clear reason why. You just weren't accepted. Frustrating, right?

This club scenario isn't too different from the fact that KYC is being used by many businesses as a convenient gatekeeping tool. A perfect excuse based on a "legal" procedure they are obliged to.

Even some exchanges may randomly use this to freeze and block funds from users, claiming these were "flagged" by a cryptic system that inspects the transactions. You are left hostage to their arbitrary decision to let you successfully pass the KYC procedure. If you choose to sidestep their invasive process, they might just hold onto your funds indefinitely.

Your identity has been stolen

KYC data has been found to be for sale on many dark net markets^3. Exchanges may have leaks or hacks, and such leaks contain very sensitive data. We're talking about the full monty: passport or ID scans, proof of address, and even those awkward selfies where you're holding up your ID next to your face. All this data is being left to the mercy of the (mostly) "trust-me-bro" security systems of such companies. Quite scary, isn't it?

As cheap as $10 for 100 documents, with discounts applying for those who buy in bulk, the personal identities of innocent users who passed KYC procedures are for sale. ^3

In short, if you have ever passed the KYC/AML process of a crypto exchange, your privacy is at risk of being compromised, or it might even have already been compromised.

(they) Know Your Coins

You may already know that Bitcoin and most cryptocurrencies have a transparent public blockchain, meaning that all data is shown unencrypted for everyone to see and recorded forever. If you link an address you own to your identity through KYC, for example, by sending an amount from a KYC exchange to it, your Bitcoin is no longer pseudonymous and can then be traced.

If, for instance, you send Bitcoin from such an identified address to another KYC'ed address (say, from a friend), everyone having access to that address-identity link information (exchanges, governments, hackers, etc.) will be able to associate that transaction and know who you are transacting with.

Conclusions

To sum up, KYC does not protect individuals; rather, it's a threat to our privacy, freedom, security and integrity. Sensible information flowing through the internet is thrown into chaos by dubious security measures. It puts borders between many potential customers and businesses, and it helps governments and companies track innocent users. That's the chaos KYC has stirred.

The criminals are using stolen identities from companies that gathered them thanks to these very same regulations that were supposed to combat them. Criminals always know how to circumvent such regulations. In the end, normal people are the most affected by these policies.

The threat that KYC poses to individuals in terms of privacy, security and freedom is not to be neglected. And if we don’t start challenging these systems and questioning their efficacy, we are just one step closer to the dystopian future that is now foreseeable.

Edited 20/03/2024 * Add reference to the 1% statement on Rights for Illusions section to an article where Chainalysis found that only 0.34% of the transaction volume with cryptocurrencies in 2023 was attributable to criminal activity ^1

Imagine a world where your favorite health and fitness apps—diet trackers, meditation tools, cardio and strength training platforms, even therapy apps—can all work together seamlessly. Not because they're owned by the same company, but because they speak a common, open language. That's the future NIP-101h is building on Nostr.

A Modular, Privacy-First Health Data Framework

NIP-101h defines a modular, privacy-first framework for sharing granular health and fitness metrics on the decentralized Nostr protocol. The core idea is simple but powerful: every health metric (weight, steps, calories, mood, and so on) gets its own unique Nostr event kind. Apps can implement only the metrics they care about, and users can choose exactly what to share, with whom, and how.

This modular approach means true interoperability. A meditation app can log mindfulness sessions, a running app can record your daily mileage, and a diet tracker can keep tabs on your nutrition—all using the same underlying standard. Each app remains independent, but your data becomes portable, composable, and, most importantly, under your control.

Why NIP-101h Matters

Interoperability

Today's health and fitness apps are walled gardens. Data is locked away in proprietary formats, making it hard to move, analyze, or combine. NIP-101h breaks down these barriers by providing a common, open standard for health metrics on Nostr. Apps can collaborate, users can migrate, and new services can emerge—without permission or lock-in.

User Control & Privacy

Health data is deeply personal. That's why NIP-101h is privacy-first: all metric values are encrypted by default using NIP-44, unless the user explicitly opts out. You decide what's public, what's private, and who gets access. Even if you want to keep everything local, that's supported too.

Extensibility

The world of health and fitness is always evolving. NIP-101h is designed to grow with it. New metrics can be added at any time via the

I. Introduction: Money as a Function of Efficiency and Preference

Money is not defined by law, but by power over productivity. In any open economy, the most economically efficient actors—those who control the most valuable goods, services, and knowledge—ultimately dictate the medium of exchange. Their preferences signal to the broader market what form of money is required to access the highest-value goods, from durable commodities to intangibles like intellectual property and skilled labor.

Whatever money these actors prefer becomes the de facto unit of account and store of value, regardless of its legal status. This emergent behavior is natural and reflects a hierarchy of monetary utility.

II. Classical Gresham’s Law: A Product of Market Distortion

Gresham’s Law, famously stated as:

"Bad money drives out good"

is only valid under coercive monetary conditions, specifically: - Legal tender laws that force the acceptance of inferior money at par with superior money. - Fixed exchange rates imposed by decree, not market valuation. - Governments or central banks backing elastic fiduciary media with promises of redemption. - Institutional structures that mandate debt and tax payments in the favored currency.

Under these conditions, superior money (hard money) is hoarded, while inferior money (soft, elastic, inflationary) circulates. This is not an expression of free market behavior—it is the result of suppressed price discovery and legal coercion.

Gresham’s Law, therefore, is not a natural law of money, but a law of distortion under forced parity and artificial elasticity.

III. The Collapse of Coercion: Inversion of Gresham’s Law

When coercive structures weaken or are bypassed—through technological exit, jurisdictional arbitrage, monetary breakdown, or political disintegration—Gresham’s Law inverts:

Good money drives out bad.

This occurs because: - Market actors regain the freedom to select money based on utility, scarcity, and credibility. - Legal parity collapses, exposing the true economic hierarchy of monetary forms. - Trustless systems (e.g., Bitcoin) or superior digital instruments (e.g., stablecoins) offer better settlement, security, and durability. - Elastic fiduciary media become undesirable as counterparty risk and inflation rise.

The inversion marks a return to monetary natural selection—not a breakdown of Gresham’s Law, but the collapse of its preconditions.

IV. Elasticity and Control

Elastic fiduciary media (like fiat currency) are not intrinsically evil. They are tools of state finance and debt management, enabling rapid expansion of credit and liquidity. However, when their issuance is unconstrained, and legal tender laws force their use, they become weapons of economic coercion.

Banks issue credit unconstrained by real savings, and governments enforce the use of inflated media through taxation and courts. This distorts capital allocation, devalues productive labor, and ultimately hollows out monetary confidence.

V. Monetary Reversion: The Return of Hard Money

When the coercion ends—whether gradually or suddenly—the monetary system reverts. The preferences of the productive and wealthy reassert themselves:

• Superior money is not just saved—it begins to circulate.
• Weaker currencies are rejected not just for savings, but for daily exchange.
• The hoarded form becomes the traded form, and Gresham’s Law inverts completely.

Bitcoin, gold, and even highly credible stable instruments begin to function as true money, not just stores of value. The natural monetary order returns, and the State becomes a late participant, not the originator of monetary reality.

VI. Conclusion

Gresham’s Law operates only under distortion. Its inversion is not an anomaly—it is a signal of the collapse of coercion. The monetary system then reorganizes around productive preference, technological efficiency, and economic sovereignty.

The most efficient market will always dictate the form of hard money. The State can delay this reckoning through legal force, but it cannot prevent it indefinitely. Once free choice returns, bad money dies, and good money lives again.

Introduction

Public companies that hold Bitcoin on behalf of investors (often issuing securities backed by those Bitcoin holdings) have faced growing pressure to demonstrate proof of reserves – evidence that they genuinely hold the cryptocurrency they claim. One approach is to publish the company’s Bitcoin wallet addresses so that anyone can verify the balances on the blockchain. This practice gained momentum after high-profile crypto collapses (e.g. FTX in 2022) eroded trust, leading major exchanges and fund issuers like Binance, Kraken, OKX, and Bitwise to publicize wallet addresses as proof of assets . The goal is transparency and reassurance for investors. However, making wallet addresses public comes with significant security and privacy risks. This report examines those risks – from cybersecurity threats and blockchain tracing to regulatory and reputational implications – and weighs them against the transparency benefits of on-chain proof of reserves.

Proof of Reserves via Public Wallet Addresses

In the cryptocurrency ethos of “don’t trust – verify,” on-chain proof of reserves is seen as a powerful tool. By disclosing wallet addresses (or cryptographic attestations of balances), a company lets investors and analysts independently verify that the Bitcoin reserves exist on-chain. For example, some firms have dashboards showing their addresses and balances in real time . In theory, this transparency builds trust by proving assets are not being misreported or misused. Shareholders gain confidence that the company’s Bitcoin holdings are intact, potentially preventing fraud or mismanagement.

Yet this approach essentially sacrifices the pseudonymity of blockchain transactions. Publishing a wallet address ties a large, known institution to specific on-chain funds. While Bitcoin addresses are public by design, most companies treat their specific addresses as sensitive information. Public proof-of-reserve disclosures break that anonymity, raising several concerns as detailed below.

Cybersecurity Threats from Visible Wallet Balances

Revealing a wallet address with a large balance can make a company a prime target for hackers and cybercriminals. Knowing exactly where significant reserves are held gives attackers a clear blueprint. As Bitcoin advocate (and MicroStrategy Executive Chairman) Michael Saylor warned in 2025, “publicly known wallet addresses become prime targets for malicious actors. Knowing where significant reserves are held provides hackers with a clear target, potentially increasing the risk of sophisticated attacks” . In other words, publishing the address increases the attack surface – attackers might intensify phishing campaigns, malware deployment, or insider bribery aimed at obtaining the keys or access to those wallets.

Even if the wallets are secured in cold storage, a public address advertisement may encourage attempts to penetrate the organization’s security. Custodians and partners could also be targeted. Saylor noted that this exposure isn’t just risky for the company holding the Bitcoin; it can indirectly put their custodial providers and related exchanges at risk as well . For instance, if a third-party custodian manages the wallets, hackers might attempt to breach that custodian knowing the reward (the company’s Bitcoin) is great.

Companies themselves have acknowledged these dangers. Grayscale Investments, which runs the large Grayscale Bitcoin Trust (GBTC), pointedly refused to publish its wallet addresses in late 2022, citing “security concerns” and complex custody arrangements that have “kept our investors’ assets safe for years” . Grayscale implied that revealing on-chain addresses could undermine those security measures, and it chose not to “circumvent complex security arrangements” just to appease public demand . This highlights a key point: corporate treasury security protocols often assume wallet details remain confidential. Publicizing them could invalidate certain assumptions (for example, if an address was meant to be operationally secret, it can no longer serve that role once exposed).

Additionally, a publicly known trove of cryptocurrency might invite physical security threats. While not a purely “cyber” issue, if criminals know a particular company or facility controls a wallet with, say, thousands of Bitcoin, it could lead to threats against personnel (extortion or coercion to obtain keys). This is a less common scenario for large institutions (which typically have robust physical security), but smaller companies or key individuals could face elevated personal risk by being associated with huge visible crypto reserves.

In summary, cybersecurity experts consider public proof-of-reserve addresses a double-edged sword: transparency comes at the cost of advertising exactly where a fortune is held. As Saylor bluntly put it, “the conventional way of issuing proof of reserves today is actually insecure… This method undermines the security of the issuer, the custodian, the exchanges and the investors. This is not a good idea”  . From a pure security standpoint, broadcasting your wallets is akin to drawing a bullseye on them.

Privacy Risks: Address Clustering and Blockchain Tracing

Blockchain data is public, so publishing addresses opens the door to unwanted analytics and loss of privacy for the business. Even without knowing the private keys, analysts can scrutinize every transaction in and out of those addresses. This enables address clustering – linking together addresses that interact – and other forms of blockchain forensics that can reveal sensitive information about the company’s activities.

One immediate risk is that observers can track the company’s transaction patterns. For example, if the company moves Bitcoin from its reserve address to an exchange or to another address, that move is visible in real time. Competitors, investors, or even attackers could deduce strategic information: perhaps the company is planning to sell (if coins go to an exchange wallet) or is reallocating funds. A known institution’s on-chain movements can thus “reveal strategic movements or holdings”, eroding the company’s operational privacy . In a volatile market, advance knowledge of a large buy or sell by a major player could even be exploited by others (front-running the market, etc.).

Publishing one or a few static addresses also violates a basic privacy principle of Bitcoin: address reuse. Best practice in Bitcoin is to use a fresh address for each transaction to avoid linking them  . If a company continuously uses the same “proof of reserve” address, all counterparties sending funds to or receiving funds from that address become visible. Observers could map out the company’s business relationships or vendors by analyzing counterparties. A Reddit user commenting on an ETF that published a single address noted that “reusing a single address for this makes me question their risk management… There are much better and more privacy-preserving ways to prove reserves… without throwing everything in a single public address” . In other words, a naive implementation of proof-of-reserve (one big address) maximizes privacy leakage.

Even if multiple addresses are used, if they are all disclosed, one can perform clustering analysis to find connections. This happened in the Grayscale case: although Grayscale would not confirm any addresses, community analysts traced and identified 432 addresses likely belonging to GBTC’s custodial holdings by following on-chain traces from known intermediary accounts . They managed to attribute roughly 317,705 BTC (about half of GBTC’s holdings) to those addresses . This demonstrates that even partial information can enable clustering – and if the company directly published addresses, the task becomes even easier to map the entirety of its on-chain asset base.

Another threat vector is “dusting” attacks, which become more feasible when an address is publicly known. In a dusting attack, an adversary sends a tiny amount of cryptocurrency (dust) to a target address. The dust itself is harmless, but if the target address ever spends that dust together with other funds, it can cryptographically link the target address to other addresses in the same wallet. Blockchain security researchers note that “with UTXO-based assets, an attacker could distribute dust to an address to reveal the owner’s other addresses by tracking the dust’s movement… If the owner unknowingly combines this dust with their funds in a transaction, the attacker can… link multiple addresses to a single owner”, compromising privacy . A company that publishes a list of reserve addresses could be systematically dusted by malicious actors attempting to map out all addresses under the company’s control. This could unmask cold wallet addresses that the company never intended to publicize, further eroding its privacy and security.

Investor confidentiality is another subtle concern. If the business model involves individual investor accounts or contributions (for instance, a trust where investors can deposit or withdraw Bitcoin), public addresses might expose those movements. An outside observer might not know which investor corresponds to a transaction, but unusual inflows/outflows could signal actions by big clients. In extreme cases, if an investor’s own wallet is known (say a large investor announces their involvement), one might link that to transactions in the company’s reserve addresses. This could inadvertently reveal an investor’s activities or holdings, breaching expectations of confidentiality. Even absent direct identification, some investors might simply be uncomfortable with their transactions being part of a publicly traceable ledger tied to the company.

In summary, publishing reserve addresses facilitates blockchain tracing that can pierce the veil of business privacy. It hands analysts the keys to observe how funds move, potentially exposing operational strategies, counterparties, and internal processes. As one industry publication noted, linking a large known institution to specific addresses can compromise privacy and reveal more than intended . Companies must consider whether they are ready for that level of transparency into their every on-chain move.

Regulatory and Compliance Implications

From a regulatory perspective, wallet address disclosure lies in uncharted territory, but it raises several flags. First and foremost is the issue of incomplete information: A wallet address only shows assets, not the company’s liabilities or other obligations. Regulators worry that touting on-chain holdings could give a false sense of security. The U.S. Securities and Exchange Commission (SEC) has cautioned investors to “not place too much confidence in the mere fact a company says it’s got a proof-of-reserves”, noting that such reports “lack sufficient information” for stakeholders to ascertain if liabilities can be met . In other words, a public company might show a big Bitcoin address balance, but if it has debts or customer liabilities of equal or greater value, the proof-of-reserve alone is “not necessarily an indicator that the company is in a good financial position” .

This regulatory stance implies that address disclosure, if done, must be paired with proper context. A public company would likely need to clarify in its financial statements or investor communications that on-chain reserves are unencumbered (not pledged as loan collateral, not already sold forward, etc.) and that total liabilities are accounted for. Otherwise, there’s a risk of misleading investors, which could have legal consequences. For example, if investors interpret the on-chain balance as proof of solvency but the company actually had leveraged those bitcoins for loans, lawsuits or regulatory enforcement could follow for misrepresentation.

There’s also a compliance burden associated with revealing addresses. Once an address is known to be the company’s, that company effectively must monitor all transactions related to it. If someone sends funds to that address (even without permission), the company might receive tainted coins (from hacked sources or sanctioned entities). This could trigger anti-money laundering (AML) red flags. Normally, compliance teams can ignore random deposits to unknown wallets, but they cannot ignore something sent into their publicly identified corporate wallet. Even a tiny dust amount sent from a blacklisted address could complicate compliance – for instance, the company would need to prove it has no relation to the sender and perhaps even avoid moving those tainted outputs. Being in the open increases such exposure. Threat actors might even exploit this by “poisoning” a company’s address with unwanted transactions, just to create regulatory headaches or reputational smears.

Another consideration is that custodial agreements and internal risk controls might forbid public disclosure of addresses. Many public companies use third-party custodians for their Bitcoin (for example, Coinbase Custody, BitGo, etc.). These custodians often treat wallet details as confidential for security. Grayscale noted that its Bitcoin are custodied on Coinbase and implied that revealing on-chain info would interfere with security arrangements  . It’s possible that some custodians would object to their clients broadcasting addresses, or might require additional assurances. A company going against such advice might be seen as negligent if something went wrong.

Regulators have so far not mandated on-chain proofs for public companies – in fact, recent laws have exempted public companies from proof-of-reserve mandates on the assumption they are already subject to rigorous SEC reporting. For example, a Texas bill in 2023 required crypto exchanges and custodians to provide quarterly proof-of-reserves to the state, but it “specifically carved out public reporting companies” since they already file audited financials with the SEC . The rationale was that between SEC filings and audits, public companies have oversight that private crypto firms lack . However, this also highlights a gap: even audited financials might not verify 100% of crypto assets (auditors often sample balances). Some observers noted that standard audits “may not ever include the 100% custodial asset testing contemplated by proof of reserves”, especially since quarterly SEC filings (10-Q) are often not audited . This puts public companies in a nuanced position – they are trusted to use traditional audits and internal controls, but the onus is on them if they choose to add extra transparency like on-chain proofs.

Finally, securities regulators focus on fair disclosure and accuracy. If a company publicly posts addresses, those essentially become investor disclosures subject to anti-fraud rules. The firm must keep them up to date and accurate. Any mistake (such as publishing a wrong address or failing to mention that some coins are locked up or lent out) could attract regulatory scrutiny for being misleading. In contrast, a formal audit or certification from a third-party comes with standards and disclaimers that are better understood by regulators. A self-published wallet list is an unprecedented form of disclosure that regulators haven’t fully vetted – meaning the company bears the risk if something is misinterpreted.

In summary, wallet address disclosure as proof-of-reserve must be handled very carefully to avoid regulatory pitfalls. The SEC and others have warned that on-chain assets alone don’t tell the whole story . Public companies would need to integrate such proofs with their official reporting in a responsible way – otherwise they risk confusion or even regulatory backlash for giving a false sense of security.

Reputational and Operational Risks

While transparency is meant to enhance reputation, in practice public wallet disclosures can create new reputational vulnerabilities. Once an address is public, a company’s every on-chain action is under the microscope of the crypto community and media. Any anomaly or perceived misstep can snowball into public relations problems.

One vivid example occurred with Crypto.com in late 2022. After the exchange published its cold wallet addresses to prove reserves (a move prompted by the FTX collapse), on-chain analysts quickly noticed a “suspicious transfer of 320,000 ETH” – about 82% of Crypto.com’s Ether reserves – moving from their cold wallet to another exchange (Gate.io)  . This large, unexpected transfer sparked immediate panic and FUD (fear, uncertainty, and doubt) on social media. Observers speculated that Crypto.com might be insolvent or was manipulating snapshots of reserves by borrowing funds. The CEO had to publicly respond, admitting it was an operational error – the ETH was supposed to go to a new cold storage address but ended up at a whitelisted external address by mistake . The funds were eventually returned, but not before reputational damage was done: the incident made headlines about mishandled funds and rattled user confidence  . This case illustrates how full public visibility can turn an internal slip-up into a highly public crisis. If the addresses had not been public, the mistake might have been quietly corrected; with on-chain transparency, there was nowhere to hide and no way to control the narrative before the public drew worst-case conclusions.

Even routine operations can be misinterpreted. Blockchain data lacks context – analysts may jump to conclusions that hurt a company’s reputation even if nothing is actually wrong. For instance, Binance (the world’s largest crypto exchange) encountered scrutiny when on-chain observers noted that one of its reserve wallets (labeled “Binance 8”) contained far more assets than it should have. This wallet was meant to hold collateral for Binance’s issued tokens, but held an excess balance, suggesting possible commingling of customer funds with collateral  . Bloomberg and others reported a ~$12.7 billion discrepancy visible on-chain . Binance had to acknowledge the issue as a “clerical error” and quickly separate the funds, all under the glare of public attention  . While Binance maintained that user assets were fully backed and the mistake was purely operational, the episode raised public concern over Binance’s practices, feeding a narrative that even the largest exchange had internal control lapses. The key point is that public proof-of-reserves made the lapse obvious to everyone, forcing a reactive explanation. The reputational hit (even if temporary) was an operational risk of being so transparent.

Additionally, strategic confidentiality is lost. If a company holding Bitcoin as a reserve asset decides to make a major move (say, reallocating to a different wallet, or using some Bitcoin for a strategic investment or loan), doing so with known addresses broadcasts that strategy. Competitors or market analysts can infer things like “Company X is moving 10% of its BTC — why? Are they selling? Hedging? Using it as collateral?” This can erode any competitive advantage of keeping financial strategies discreet. It might even affect the company’s stock price if investors interpret moves negatively. For example, if a blockchain analysis shows the company’s reserves dropping, shareholders might fear the company sold Bitcoin (perhaps due to financial distress), even if the reality is benign (like moving funds to a new custodian). The company would be forced into continuous public explanation of on-chain actions to prevent misunderstanding.

There’s also a risk of exposing business partnerships. Suppose the company uses certain exchanges or OTC desks to rebalance its holdings – transactions with those service providers will be visible and could link the company to them. If one of those partners has issues (say a hacked exchange or a sanctioned entity inadvertently), the company could be reputationally contaminated by association through the blockchain trail.

Finally, not all publicity is good publicity in the crypto world. A public proof-of-reserve might invite armchair auditors to scrutinize and criticize every aspect of the company’s crypto management. Minor issues could be blown out of proportion. On the flip side, if a company chooses not to publish addresses, it could face reputational risk from a different angle: skeptics might question why it isn’t being transparent. (Indeed, Grayscale’s refusal to disclose wallet addresses led to social media chatter about whether they truly held all the Bitcoin they claimed, contributing to investor nervousness and a steep discount on GBTC shares .) Thus, companies are in a delicate spot: share too much and every move invites scrutiny; share too little and you breed distrust.

Balancing Transparency Benefits vs. Risks

The central question is whether the benefit of proving reserve holdings to investors outweighs these security and privacy risks. It’s a classic risk-reward calculation, and opinions in the industry are divided.

On the side of transparency, many argue that the credibility and trust gained by proof-of-reserves is invaluable. Advocates note that Bitcoin was designed for open verification – “on-chain auditability and permissionless transparency” are core features . By embracing this, companies demonstrate they are good stewards of a “trustless” asset. In fact, some believe public companies have a duty to be extra transparent. A recent Nasdaq report contended that “when a publicly traded company holds Bitcoin but offers no visibility into how that Bitcoin is held or verified, it exposes itself to multiple levels of risk: legal, reputational, operational, and strategic”, undermining trust . In that view, opacity is riskier in the long run – a lack of proof could weaken investor confidence or invite regulatory suspicion. Shareholders and analysts may actually penalize a company that refuses to provide verifiable proof of its crypto assets .

Transparency done right can also differentiate a firm as a leader in governance. Publishing reserve data (whether via addresses or through third-party attestations) can be seen as a commitment to high standards. For example, Metaplanet, an investment firm, publicly discloses its BTC reserve addresses and even provides a live dashboard for anyone to verify balances . This proactive openness signals confidence and has been touted as an industry best practice in some quarters. By proving its reserves, a company can potentially avoid the fate of those that lost public trust (as happened with opaque crypto firms in 2022). It’s also a means to preempt false rumors – if data is out in the open, misinformation has less room to grow.

However, the pro-transparency camp increasingly acknowledges that there are smarter ways to achieve trust without courting all the risks. One compromise is using cryptographic proofs or audits instead of plain address dumps. For instance, exchanges like Kraken have implemented Merkle tree proof-of-reserves: an independent auditor verifies all customer balances on-chain and provides a cryptographic report, and customers can individually verify their account is included without the exchange revealing every address publicly. This method proves solvency to those who need to know without handing over a complete roadmap to attackers. Another emerging solution is zero-knowledge proofs, where a company can prove knowledge or ownership of certain assets without revealing the addresses or amounts to the public. These technologies are still maturing, but they aim to deliver the best of both worlds: transparency and privacy.

On the side of caution, many experts believe the risks of full public disclosure outweigh the incremental gain in transparency, especially for regulated public companies. Michael Saylor encapsulates this viewpoint: he calls on-chain proof-of-reserve “a bad idea” for institutions, arguing that it “offers one-way transparency” (assets only) and “leaves organizations open to cyberattacks” . He stresses that no serious security expert would advise a Fortune 500 company to list all its wallet addresses, as it essentially compromises corporate security over time . Saylor and others also point out the pointlessness of an assets-only proof: unless you also prove liabilities, showing off reserves might even be dangerous because it could lull investors into a false sense of security .

Regulators and traditional auditors echo this: proof-of-reserves, while a useful tool, “is not enough by itself” to guarantee financial health . They advocate for holistic transparency – audits that consider internal controls, liabilities, and legal obligations, not just a snapshot of a blockchain address  . From this perspective, a public company can satisfy transparency demands through rigorous third-party audits and disclosures rather than raw on-chain data. Indeed, public companies are legally bound to extensive reporting; adding public crypto addresses on top may be seen as redundant and risky.

There is also an implicit cost-benefit analysis: A successful attack resulting from over-sharing could be catastrophic (loss of funds, legal liability, reputational ruin), whereas the benefit of public proof is somewhat intangible (improved investor sentiment, which might be achieved via other assurance methods anyway). Given that trade-off, many firms err on the side of caution. As evidence, few if any U.S.-listed companies that hold Bitcoin have published their wallet addresses. Instead, they reference independent custodians and audits for assurance. Even crypto-native companies have pulled back on full transparency after realizing the downsides – for example, some auditing firms halted issuing proof-of-reserves reports due to concerns about how they were interpreted and the liability involved  .

Industry best practices are still evolving. A prudent approach gaining favor is to prove reserves without leaking sensitive details. This can involve disclosing total balances and having an auditor or blockchain oracle confirm the assets exist, but without listing every address publicly. Companies are also encouraged to disclose encumbrances (whether any of the reserves are collateralized or lent out) in tandem, to address the liabilities issue . By doing so, they aim to achieve transparency and maintain security.

In evaluating whether to publish wallet addresses, a company must ask: Will this level of openness meaningfully increase stakeholder trust, or would a more controlled disclosure achieve the same goal with less risk? For many public companies, the answer has been to avoid public addresses. The risks – from attracting hackers to revealing strategic moves – tend to outweigh the marginal transparency benefit in their judgment. The collapse of unregulated exchanges has certainly proven the value of reserve verification, but public companies operate in a different context with audits and legal accountability. Thus, the optimal solution may be a middle ground: proving reserves through vetted processes (auditor attestations, cryptographic proofs) that satisfy investor needs without blatantly exposing the company’s financial backend to the world.

Conclusion

Publishing Bitcoin wallet addresses as proof of reserves is a bold transparency measure – one that speaks to crypto’s ideals of open verification – but it comes with a laundry list of security considerations. Public companies weighing this approach must contend with the heightened cybersecurity threat of advertising their treasure troves to hackers, the loss of privacy and confidentiality as on-chain sleuths dissect their every transaction, and potential regulatory complications if such disclosures are misunderstood or incomplete. Real-world incidents illustrate the downsides: firms that revealed addresses have seen how quickly online communities flag (and sometimes misinterpret) their blockchain moves, causing reputational turbulence and forcing rapid damage control  .

On the other hand, proving reserves to investors is important – it can prevent fraud and bolster trust. The question is how to achieve it without incurring unacceptable risk. Many experts and industry leaders lean towards the view that simply publishing wallet addresses is too risky a method, especially for public companies with much to lose  . The risks often do outweigh the direct benefits in such cases. Transparency remains crucial, but it can be provided in safer ways – through regular audits, cryptographic proofs that don’t expose all wallet details, and comprehensive disclosures that include liabilities and controls.

In conclusion, while on-chain proof of reserves via public addresses offers a tantalizing level of openness, it must be approached with extreme caution. For most public companies, the smart strategy is to balance transparency with security: verify and show investors that assets exist and are sufficient, but do so in a controlled manner that doesn’t compromise the very assets you’re trying to protect. As the industry matures, we can expect more refined proof-of-reserve practices that satisfy the demand for honesty and solvency verification without unduly endangering the enterprise. Until then, companies will continue to tread carefully, mindful that transparency is only truly valuable when it doesn’t come at the price of security and trust.

BCL2 took place today. I drew the third pick.

Here are the results:

1.3 Ja’Marr Chase — I didn’t want Christian McCalfinjury, of whom I already have a share, so I was set on CeeDee Lamb or Tyreek Hill if they were there. But I had an inkling they might go 1-2 in which case Ja’Marr Chase was narrowly my fallback over Amon Ra St. Brown and Breece Hall. Chase has St. Brown’s target upside, but with a much bigger vertical game. The biggest negative for him is Burrow’s health, but Burrow’s fine now, and anyone can get hurt. I also thought maybe I’d draft Tee Higgins if he fell to me in Round 5 (which was unlikely) in which case I’d try to get Burrow too.

2.10 Jaylen Waddle — It was Waddle the solid, boring pick or Malik Nabers the fun, exciting one. Team 4 did me a favor and took De’Von Achane out of the equation — I have Achane in BCL1, and while I love his upside, he’s not the kind of player to which you tie all your teams. I narrowly went Waddle who actually has upside too if Tyreek Hill ever got hurt.

3.10 Malik Nabers — I couldn’t believe it, but Nabers made it all the way back despite third-round reversal. I love Nabers, but I think the market is over-drafting him slightly relative to his projected target share. I mean he might get 150, but I think 130-140 Daniel Jones targets is more likely, and that’s a third, not a second-round pick. ** 4.3 Stefon Diggs** — This was going perfectly. Had Nabers been taken, I would have gone Diggs in Round 3, but he was still there four picks later. I’ve mentioned before I have Diggs as a top-10-ish WR.

5.10 Anthony Richardson — I took Reachardson early because I didn’t need another receiver (would be my first bench spot), the running back I liked best was still likely to be back in Round 6 too, and I couldn’t bring myself to take Kyle Pitts who has burned me so many times. ** 6.3 Rhamondre Stevenson** — Backs were flying off the board in this draft which figures because I went so WR-heavy, but I think Stevenson is good, and there’s no way the Patriots offense won’t be better than last year’s just from pure regression to the mean.

7.10 Javonte Williams — Another good back on a bad team, Williams’ 2023 was not representative given he was only one year removed from an ACL tear. We should see the real version this year, and I expect him to be the main guy in Denver. ** 8.3 Ladd McConkey** — This was a luxury pick, but I liked the value too much, and I wasn’t in love with any of the RB or TE at cost. (I missed out on Jake Ferguson right after the Williams pick.) But the McConkey pick cost me Zack Moss, Devin Singletary, Nick Chubb, Brian Robinson, Chase Brown, Blake Corum and Tyjae Spears.

9.10 Brock Bowers — I missed out on David Njoku by one pick too, so it was time to get Bowers, the last of that tier of tight ends.

10.3 Jerome Ford — He’s Nick Chubb’s backup at worst, and that assumes Chubb will even be at full health any time soon.

11.10 Rashid Shaheed — Another luxury pick, but I couldn’t pass him up here. I’ve mentioned many times, I think he’s as good as Chris Olave, and there are only two of them now, so Shaheed should see his share of targets, either way. Shaheed cost me Zach Charbonnet and Cole Kmet though.

12.3 J.K. Dobbins — I’m not a big Gus Edwards believer — he’s 29 and with a limited skill set. Dobbins can never stay healthy, but worth a flyer here on what should be a run-heavy offense.

13.10 Kimani Vidal — Sounds like a high-end hair salon, but he’s actually the fallback if Dobbins and Edwards don’t pan out. I like his build (5-8, 215), speed and pass-catching skills.

14.3 Bucky Irving — I’m not sold on Rachaad White being anything special, and Irving is his backup. I needed a lot of lottery ticket backs with this build. ** 15.10 Khalil Herbert** — There are rumors he could be moved, but either way, I don’t trust D’Andre Soft, and Roschon Johnson is just a guy.

16.3 Jonnu Smith — This was a bit early per ADP, but I needed a second TE, and Smith has a lot of upside in an offense that’s so top heavy.

17.10 Justin Fields — In the likely event Russell Wilson is cooked, Fields is a top-10 fantasy quarterback already. I thought about Danny Dimes too. ** 18.3 Younghoe Koo** — I’m tired of drafting Justin Tucker every year, felt it was time for a Younghoe.

19.10 Giants Defense — They get the Sam Darnold Vikings in Week 1, the Football Team in Week 2. And they now have three elite pass rushers in Kayvon Thibodeaux, Dexter Lawrence and Brian Burns.

20.3 Roman Wilson — I wanted to take Danny Dimes, but Wilson could easily be the Steelers’ slot guy — Van Jefferson is bad, and even George Pickens is more of a highlight-reel guy who doesn’t command massive target share.

Deutschland ist eines der wenigen Länder mit einer gesetzlich verankerten ausnahmslosen Schulbesuchspflicht. Mit den Schulschließungen in der Corona-Zeit wurde das Gesetz jedoch faktisch plötzlich außer Kraft gesetzt. Alle mussten zu Hause lernen. Als die Schulen danach wieder offen waren, wurden die Kinder mit Maskenpflicht, Tests und Impfdruck gequält. Nicht selten traten bei den Schülern Krankheiten und psychische Störungen auf. Nicht wenige Eltern suchten im Gespräch mit dem Lehrerkollegium nach Lösungen für ihre Kinder. In den meisten Fällen war das nicht möglich. Die Lehrer waren auf die neue Ideologie und die Durchsetzung der Maßnahmen eingeschworen und hatten Angst. Einige Eltern haben ihre Kinder dann in eigener Verantwortung aus der Schule genommen und zu Hause selbst unterrichtet. An manchen Orten fanden sich Gemeinschaften, wo die Kinder in Gruppen lernten. Während viele Lerngemeinschaften nicht mehr existieren, hat die Familie von Katharina den Unterricht für ihre drei Kinder in Eigenregie etabliert. Inzwischen haben sie dafür sogar „den Segen“ von Familiengericht und Jugendamt.

Katharina und Johannes leben mit ihren drei Wunschkindern Aurelius (15), Benjamin (14) und Friedrich (10) in einem Vorort von Leipzig. Die Familie wohnte früher in der Stadt. In der Corona-Zeit haben sie sich mit dem Physiotherapie- & Seminarzentrum Curasanus eine Existenz auf dem Land aufgebaut und begehen diesen Sommer ihr 20-jähriges Praxis-Jubiläum. Katharina hat ihre Arbeit als Physiotherapeutin weitgehend aufgegeben, um sich als Mama und Lernbegleiterin ihren Kindern widmen zu können. Daneben bietet sie Vorträge und Workshops an, übernimmt einen großen Teil der Praxis-Organisation und ist Manager, Rezeptionistin und Vertriebler der eigenen Firma. Wir besuchten einen ihrer Lachyoga-Kurse. Dabei erlebten wir ihr Zusammenspiel mit den drei Kindern. Anschließend stellten wir Katharina unsere Fragen zum Freilernen.

Im unmittelbaren Umfeld wird die Familie bestaunt und geachtet. Sie haben sich bewusst für das Freilernen entschieden. Die Kinder wurden ohne Test nicht mehr in die Schule gelassen. Auch andere Zwangsmaßnahmen wie die Maske wollten die Eltern den Kindern ersparen. Besonders Benjamin hatte traumatische Erlebnisse. Seine Lehrerin schmiss mit dem Schlüssel nach den Schülern und wandte andere schwarze Pädagogik an. Er ging ständig mit Bauchschmerzen ins Bett. Ein weiterer Punkt ist die Masernimpfung. Die Kinder könnten zwar zur Schule gehen, aber die Eltern werden mit rechtlichen Maßnahmen und Zwangszahlungen belegt. Da Katharina in ihrer Praxis viele Erkrankungen als Folge der Masernimpfung beobachten konnte, lehnt sie die Pflichtimpfung ab. Die Eltern haben kein Vertrauen mehr in die staatliche Schulerziehung mit all dem Zwang und den Erpressungen. Als die Familie den Entschluss gefasst hatte, die Kinder nicht mehr in die Schule zu schicken, haben sie ihre Praxis vorübergehend geschlossen, ihr Haus verkauft und sind auf Reisen gegangen. Die beiden großen Kinder wurden von der Schule abgemeldet. Nach der Rückkehr haben sie dann mit einem neuen Leben auf dem Land begonnen.

Lernen ohne Schule: Wie geht das?

„Wissen ist Macht und eine Holschuld“, sagt uns Katharina. Das ist ihr Motto und motiviert auch die Kinder. Mit dem Unterricht zu Hause macht die Familie ihre eigene Studie und zeigt, dass Lernen auch anders geht als in der Schule. Die Eltern können viel besser auf jedes einzelne Kind eingehen. Johannes arbeitete früher als Straßenbauer. Er unterstützt die Jungs vor allem in Mathematik, Geometrie und Physik sowie bei handwerklichen Fertigkeiten. Katharinas Stärken liegen in Deutsch, Sprachen und Organisation. Unter den Patienten ihrer Praxis gibt es Lehrer, die ihnen helfen. Weitere Unterstützung kommt von Freunden und Bekannten. Bei bestimmten Projekten treffen sie auf andere Freilernerkinder. „Das Netzwerk wird immer größer, es wird immer schöner und interessanter“, sagt Katharina. Man geht mit vielen anderen einen gemeinsamen Weg, verlässt dabei eingetretene Pfade und erkundet neue Themenfelder wie Mediengestaltung, freie Energie, Elektrotherapie, meditatives und Improvisations-Zeichnen. „Ich sprudele vor Ideen. Sie kommen in mein Feld, und dann mache ich was draus“, sagt Katharina. Die Jungs sind in Wurzen im Ringelnatz-Literaturkreis. Dort schreiben sie Drehbuchgeschichten und haben einen Film produziert. Sie suchen sich Projekte oder kreieren neue, wie mit dem Planetarium Eilenburg. Diese Zusammenarbeit hat sich sehr gut entwickelt. Dort lernen 4- bis 15-Jährige zusammen. Die drei Jungs spielen Klavier. Erdkunde und Geschichte erleben die Kinder auch dadurch, dass die Familie Hauptstädte oder die bosnischen Pyramiden selbst erkundet. Dabei erweist es sich als Vorteil, nicht auf die Ferienzeiten angewiesen zu sein.

Als Physiotherapeutin ist Katharina bewusst, dass man neue Lernstrategien entwickeln muss. Die Kinder lernen unterschiedlich. Jedes Kind hat seinen eigenen Charakter. Aurelius benötigt eher eine 1:1-Betreuung. Darauf kann Katharina viel individueller eingehen als die staatliche Schule. Es ist aber auch aufwendiger und anstrengender. Besonderen Wert legt sie darauf, dass rechte und linke Gehirnhälfte gleichmäßig beansprucht werden. Lernphasen werden immer wieder mit Entspannungs- oder Bewegungsphasen kombiniert. Sie weiß, dass den Kindern zuerst die Grundlagen des Lesens, Rechnens und Schreibens vermittelt werden müssen. Dann sind sie in der Lage, sich alles Weitere selbst anzueignen – Unterstützung vorausgesetzt. „Besonders das Schreiben mit der eigenen Hand ist wichtig für die Vernetzung der beiden Gehirnhälften“, sagt Katharina. Dafür nehmen sich die Eltern Zeit. Die Kinder führen Tagebuch. Außerdem halten es die Eltern für wichtig, den Kindern Werte und Tugenden wie Dankbarkeit, Verlässlichkeit, Beharrlichkeit, Aufrichtigkeit, Ehrlichkeit und die zehn Gebote zu vermitteln. Katharina und Johannes sind beide religiös begleitet aufgewachsen. Heute sehen sie die Kirche als Institution kritisch. Angebunden an die Schöpfung und im Gottvertrauen erschaffen und schöpfen sie Leben und Lebensraum aus eigener Kraft – so erklärt es uns Katharina.

Ein weiteres Thema sind die Funktionen des Körpers und wie sich die Kinder gesund erhalten können. Vieles lernen sie dabei in der Physiotherapiepraxis. Die Familie hat das Privileg, in ihrem eigenen Biorhythmus leben zu können. „Das macht sehr viel aus – wir sind alle gesund“, sagt Katharina. Der Lern- und Arbeitstag beginnt nicht vor 9 Uhr und hat eine eigene Struktur. Im Tagesablauf sind feste Verantwortlichkeiten integriert. So wechseln sich die Kinder aller drei Tage mit Tischdecken, Staubsaugen und Geschirrspüler ab. Das hilft ihnen, sich selbst zu organisieren. Das geht nicht immer reibungslos vonstatten. Wenn das Lernpensum beizeiten abgearbeitet wurde, helfen die Kinder im Haushalt oder Garten oder gehen ihrem Bewegungsdrang auf andere Weise nach. Die Eltern sind am Abend noch länger aktiv, denn die Praxis erfordert noch die eine oder andere bürokratische Pflicht. Die Familie ist sehr naturverbunden. Sie gehen viel in den Wald und in den Garten. Sie bauen selbst Gemüse und Obst an. Dabei können die Kinder zum Beispiel Erfahrungen mit Permakultur und natürlicher Düngung sammeln. Die Familie achtet auf die Ernährung, schließlich ist Katharina seit fast 25 Jahren Ernährungsberaterin. Was sie nicht selbst anbauen, wird beim Bauern des Vertrauens eingekauft. Die Jungs können selbst kochen und backen. Die Schädlichkeit von Zucker ist den Kindern schon bewusst geworden, ohne gänzlich auf Schokolade verzichten zu müssen. Medikamente gibt es im Haushalt nicht. Sie kennen sich sehr gut mit den Heilmitteln aus der Natur aus und können so ihre Selbstheilungskräfte aktivieren. Sie haben keinen Hausarzt. Natürlich hat keines der Kinder ein Handy. Bisher haben sie noch kein Verlangen danach. Die Eltern halten es für wichtig, dass die Kinder erst sicher bei Selbstorganisation und Tagesstruktur sind, bevor sie ein Handy bekommen. Katharina weist darauf hin, dass beispielsweise WhatsApp erst ab 16 Jahren zugelassen ist, und fragt sich, ob das andere Eltern wissen.

Gesetze auf Augenhöhe auslegen

Den Behörden blieben die Freilerner nicht verborgen. Sie wurden aktiv und schalteten das Familiengericht ein. Die Familie hatte keinen Anwalt und keine Rechtsschutzversicherung. Katharina erzählt uns, dass sie schließlich auf „Hilfe von oben“ gehofft habe. Irgendwer hat sie anscheinend erhört, denn sie bekamen „einen Engel“ als Verfahrensbeistand. Die Behörden waren sehr zugänglich. In den Gesprächen gab man zu, mit der Schulsituation ebenfalls nicht zufrieden zu sein. „Wir wollen so wie ihr, dass sich etwas verändert. Wir sind an Eurer Seite.“ Die Gespräche mit dem Jugendamt und der Richterin vom Familiengericht Grimma waren immer auf Augenhöhe. Schließlich legte man der Familie keine Steine in den Weg. Damit kann Katharina ihr Konzept nach außen leben und andere inspirieren. Ihre Schlussfolgerung: Eltern müssen sich ihrer Stärken bewusst werden und aus ihrer Angst herauskommen. Das Konzept muss aber zur Familie passen, denn jede Familie ist anders.

Die Basis für freies Lernen ist das Vertrauen der Eltern in ihre Kinder. Denn Kinder sind von Natur aus wissbegierig und wollen lernen. Katharina hat viel von Bertrand Stern und von Riccardo Leppe gelernt. Beiden wurde von ihren Eltern das Lernen ohne Schulbesuch ermöglicht. Mit Bertrand Stern hat Katharina Kontakt. Er wird im November am Buß- und Bettag eine kleine Fortbildung im Therapie- und Seminarzentrum geben. Für den Vorabend ist ein Vortrag geplant. Katharina zitiert Riccardo Leppe: „Es ändert sich nur was, wenn man es selbst tut.“ Er sei sich sicher, dass der Fortschritt beim Freilernen inzwischen so weit ist, dass „die Paste nicht wieder zurück in die Tube geht“.

Der Übergang zur Berufsausbildung

Die ersten Freilernerkinder kommen jetzt in das Alter, in dem sie eine Berufsausbildung beginnen können. Aurelius und Benjamin, die beiden „Großen“, machen seit Anfang des Jahres schon erste Praktika bei ortsansässigen Handwerksbetrieben. Beide Seiten sind sehr zufrieden. Durch die Praktika, die länger dauern als im schulischen Lehrplan vorgesehen, können sich die Kinder ausprobieren. Katharina findet es interessant miterleben zu dürfen, wie auf ihre Kinder reagiert wird. Bringen sie etwas mit, das die anderen nicht haben? Denken sie anders mit? Benjamin bekam schon ein Angebot, in einem Metallbau-Betrieb stundenweise mitzuarbeiten. In den Betrieben weiß man, dass die Abschlüsse der staatlichen Schulen größtenteils das Papier nicht wert sind, auf dem sie stehen. Viele verlassen die Schule und können kaum lesen und schreiben, von Selbstorganisation ganz zu schweigen. Ein Freilerner kann eine staatliche Externen-Prüfung ablegen, um einen Haupt- oder Realschulabschluss zu erwerben. Katharina: „Für eine Ausbildung bei einem privaten Unternehmer braucht man das nicht, allein der Unternehmer entscheidet über die Aufnahme des Auszubildenden“. Außerdem stehen den jungen Leuten Privatschulen oder der zweite Bildungsweg zur Verfügung. Wenn man einen praktischen Beruf ergreift, ist es immer noch möglich, sich bis zur Hochschulreife weiterzubilden. Nach mehrjährigen Tätigkeiten kann man bei den Kammern von Industrie, Handel und Handwerk (IHK und HWK) eine Abschlussprüfung ablegen, mit der man zum Studium zugelassen werden kann. Oder man geht gleich den Weg in die Selbstständigkeit.

Frei lernen weitergedacht

Während der Coronazeit haben sich in Sachsen und speziell um Leipzig herum kleine Freilernergruppen gefunden. Die Gruppen werden aktuell zusammengeführt, um zum Beispiel gemeinsam den Mathematikunterricht zu gestalten. Besonders um Dresden herum ist die Szene noch stärker ausgeprägt. Außerdem gibt es seit mehr als 20 Jahren den Bundesverband Natürlich Lernen (BVNL). Er bietet Beratung und zentrale Veranstaltungen an.

Der Wunsch nach dem freien Lernen ohne Schulzwang ist groß. Doch die meisten Eltern wollen ihre Kinder dafür irgendwo abgeben und nicht selbst unterrichten. Katharinas größter Wunsch ist es, drei bis fünf Elternpaare zu finden, die sich in die Betreuung und Unterrichtung ihrer Kinder teilen. Das größte Hindernis dafür sieht sie in den Eltern selbst. Durch ungelöste transgenerative Konflikte und unverarbeitete Familientraumata kommen sie noch nicht in ihre eigene Kraft für ein selbstbestimmtes Leben. Viele wagen es noch nicht, ihre Erwerbstätigkeit zugunsten der Kinder einzuschränken. Katharina sieht es als große Aufgabe für sich und ihre Familie, mit dem Freilernen das Gemeinschaftsbewusstsein und gute Konfliktlösungsstrategien zu entwickeln. Sie denkt dabei bereits an ihre Enkel. Aber sie weiß auch, dass die Eltern ein sehr hohes Maß an Eigeninitiative, Motivation und Selbstdisziplin aufbringen müssen. Sie würde Eltern, die sich das noch nicht zutrauen, als Traumabegleiterin zur Verfügung stehen, für einen angemessenen Energieausgleich. Diese gegenseitige Unterstützung käme Kindern und Eltern zugute. Ebenso hält sie die Idee der Mehrgenerationenerziehung für wichtig. Dabei profitieren nicht nur die Kinder. Die Erfahrungen der älteren Menschen gehen nicht verloren, sondern werden an die jüngeren Generationen weitergegeben und machen sie resilienter. Das hilft den Eltern, ihrer Erwerbsarbeit nachzugehen und Familientraumata zu bewältigen.

Katharina ist eine starke Frau und sprüht nur so vor Energie. Selbst als wir nach 21 Uhr das Therapiezentrum verlassen, sind ihr die Anstrengungen des Tages nicht anzumerken. Sie wird nicht müde beim Sprechen. Für Fragen zum Thema Freilernen kann man sich an sie wenden.

Hopefully people out there that are importers, exporters, agents, traders, wholesalers in various types of goods, will eventually post, or at the very least find some possible business leads, contacts and most importantly reviews on payments methods using Bitcoin around the World.

The Good News

1. Wholesale and Retail merchants have heard the Independent, Democratic and Republican parties are speaking in a positive tone about Bitcoin and the C word in general. Whether any of them actually will do anything in the future is another issue, note the fact that Bitcoin and the C word is being brought up in a positive way is a good.

2. Bitcoin Dev groups are opening up in more places around the World and obviously some general education, terminology and introduction to Lightning, Nostr, and hybrid point of sale systems are slowly be added to merchants retail and wholesale.

3. Shopify, As the majority of business are using Shopify, Open Node is easily added as a payment method to accept Bitcoin. (I'm using it) works fine, had to as ibexpay left supporting the USA.

4. "Just hodl" comes up more and more in conversations with my peers, asking with a confused look "When do we use it, circulate it in transacting buying or selling goods (wholesale), NOT just a cup of coffee, we are just suppose to hodl, and never use it ?

5. We have SN, we should be thankful it's a positive tool.

If anyone wants to communicate with other manufacturers, wholesalers, B2B merchants, importers, exporters, agents selling goods of any type consider reaching out as a post on SN, or contacting me directly, hopefully that you are considering using Bitcoin as the payment method.

Stay humble use SATS

由于gmail在中国被防火墙拦截了，无法打开，不想错过邮件通知。

通过自建ntfy接受gmail邮件通知。 怎么自建ntfy，后面再写。

---

2024年08月13日更新：

修改不通过添加邮件标签来标记已经发送的通知，通过Google Sheets来记录已经发送的通知。

为了不让Google Sheets文档的内容很多，导致文件变大，用脚本自动清理一个星期以前的数据。

---

准备工具

• Ntfy服务
• Google Script
• Google Sheets

操作步骤

1. 在Ntfy后台账号，设置访问令牌。
2. 添加订阅主题。
3. 进入Google Sheets创建一个表格.记住id，如下图：
4. 进入Google Script创建项目。填入以下代码（注意填入之前的ntfy地址和令牌）：

```javascript function checkEmail() { var sheetId = "你的Google Sheets id"; // 替换为你的 Google Sheets ID var sheet = SpreadsheetApp.openById(sheetId).getActiveSheet();

// 清理一星期以前的数据 cleanOldData(sheet, 7 * 24 * 60); // 保留7天（即一周）内的数据

var sentEmails = getSentEmails(sheet);

var threads = GmailApp.search('is:unread'); Logger.log("Found threads: " + threads.length);

if (threads.length === 0) return;

threads.forEach(function(thread) { var threadId = thread.getId();

if (!sentEmails.includes(threadId)) {
  thread.getMessages().forEach(sendNtfyNotification);
  recordSentEmail(sheet, threadId);
}

}); }

function sendNtfyNotification(email) { if (!email) { Logger.log("Email object is undefined or null."); return; }

var message = `发件人: ${email.getFrom() || "未知发件人"} 主题: ${email.getSubject() || "无主题"}

内容: ${email.getPlainBody() || "无内容"}`;

var url = "https://你的ntfy地址/Gmail"; var options = { method: "post", payload: message, headers: { Authorization: "Bearer Ntfy的令牌" }, muteHttpExceptions: true };

try { var response = UrlFetchApp.fetch(url, options); Logger.log("Response: " + response.getContentText()); } catch (e) { Logger.log("Error: " + e.message); } }

function getSentEmails(sheet) { var data = sheet.getDataRange().getValues(); return data.map(row => row[0]); // Assuming email IDs are stored in the first column }

function recordSentEmail(sheet, threadId) { sheet.appendRow([threadId, new Date()]); }

function cleanOldData(sheet, minutes) { var now = new Date(); var thresholdDate = new Date(now.getTime() - minutes * 60 * 1000); // 获取X分钟前的时间

var data = sheet.getDataRange().getValues(); var rowsToDelete = [];

data.forEach(function(row, index) { var date = new Date(row[1]); // 假设日期保存在第二列 if (date < thresholdDate) { rowsToDelete.push(index + 1); // 存储要删除的行号 } });

// 逆序删除（从最后一行开始删除，以避免行号改变） rowsToDelete.reverse().forEach(function(row) { sheet.deleteRow(row); }); }

```

4.Goole Script需要添加gmail服务，如图：

5.Google Script是有限制的不能频繁调用，可以设置五分钟调用一次。如图：

结尾

本人不会代码，以上代码都是通过chatgpt生成的。经过多次修改，刚开始会一直发送通知，后面修改后将已发送的通知放到一个“通知”的标签里。后续不会再次发送通知。

如需要发送通知后自动标记已读，可以把代码复制到chatgpt给你写。

คุณเคยจินตนาการถึงอนาคตที่ AI มีความฉลาดเทียบเท่ามนุษย์หรือไม่? นี่คือสิ่งที่ Sam Altman ซีอีโอของ OpenAI และทีมพันธมิตรอย่าง SoftBank, Oracle และ MGX กำลังผลักดันผ่าน โครงการ Stargate! โครงการนี้ไม่ใช่แค่เรื่องเทคโนโลยี แต่เป็นก้าวกระโดดครั้งใหญ่ของมนุษยชาติ! Stargate คืออะไร? Stargate เป็นโปรเจกต์สร้าง ศูนย์ข้อมูล AI ขนาดยักษ์ที่ใหญ่ที่สุดในประวัติศาสตร์ ด้วยเงินลงทุนเริ่มต้น 100,000 ล้านดอลลาร์ และอาจสูงถึง 500,000 ล้านดอลลาร์ ภายในปี 2029! เป้าหมายคือการพัฒนา Artificial General Intelligence (AGI) หรือ AI ที่ฉลาดเทียบเท่ามนุษย์ เพื่อให้สหรัฐฯ ครองความเป็นผู้นำด้าน AI และแข่งขันกับคู่แข่งอย่างจีน โครงการนี้เริ่มต้นที่เมือง Abilene รัฐเท็กซัส โดยจะสร้างศูนย์ข้อมูล 10 แห่ง และขยายไปยังญี่ปุ่น สหราชอาณาจักร และสหรัฐอาหรับเอมิเรตส์ ทำไม Stargate ถึงสำคัญ?
นวัตกรรมเปลี่ยนโลก: AI จาก Stargate จะช่วยพัฒนาวัคซีน mRNA รักษามะเร็งได้ใน 48 ชั่วโมง และยกระดับอุตสาหกรรมต่าง ๆ เช่น การแพทย์และความมั่นคงแห่งชาติ

สร้างงาน: คาดว่าจะสร้างงานกว่า 100,000 ตำแหน่ง ในสหรัฐฯ

พลังงานมหาศาล: ศูนย์ข้อมูลอาจใช้พลังงานถึง 1.2 กิกะวัตต์ เทียบเท่ากับเมืองขนาดใหญ่!

ใครอยู่เบื้องหลัง? Sam Altman ร่วมมือกับ Masayoshi Son จาก SoftBank และได้รับการสนับสนุนจาก Donald Trump ซึ่งผลักดันนโยบายให้ Stargate เป็นจริง การก่อสร้างดำเนินการโดย Oracle และพันธมิตรด้านพลังงานอย่าง Crusoe Energy Systems ความท้าทาย? ถึงจะยิ่งใหญ่ แต่ Stargate ก็เจออุปสรรค ทั้งปัญหาการระดมทุน ความกังวลเรื่องภาษีนำเข้าชิป และการแข่งขันจากคู่แข่งอย่าง DeepSeek ที่ใช้โครงสร้างพื้นฐานน้อยกว่า แถม Elon Musk ยังออกมาวิจารณ์ว่าโครงการนี้อาจ “ไม่สมจริง” แต่ Altman มั่นใจและเชิญ Musk ไปดูไซต์งานที่เท็กซัสเลยทีเดียว! อนาคตของ Stargate ศูนย์ข้อมูลแห่งแรกจะเริ่มใช้งานในปี 2026 และอาจเปลี่ยนโฉมวงการ AI ไปตลอดกาล นี่คือก้าวสำคัญสู่ยุคใหม่ของเทคโนโลยีที่อาจเปลี่ยนวิถีชีวิตของเรา! และไม่ใช่ประตูดวงดาวแบบในหนังนะ! ถึงชื่อ Stargate จะได้แรงบันดาลใจจากภาพยนตร์ sci-fi อันโด่งดัง แต่โครงการนี้ไม่ได้พาเราไปยังดวงดาวอื่น มันคือการเปิดประตูสู่โลกแห่ง AI ที่ทรงพลัง และอาจเปลี่ยนอนาคตของมนุษยชาติไปเลย! และไม่เหมือน universechain ของ star ของผมนะครับ

ถ้าอยากแล้วไม่หลง มันก็อยากด้วยปัญญา ความอยากอย่างนี้ท่านเรียกว่า เป็นบารมีของตน แต่ไม่ใช่ทุกคนนะที่มีปัญญา

บางคนไม่อยากจะให้มันอยาก เพราะเข้าใจว่า การมาปฏิบัติก็เพื่อระงับความอยาก ความจริงน่ะ ถ้าหากว่าไม่มีความอยาก ก็ไม่มีข้อปฏิบัติ ไม่รู้ว่าจะทำอะไร ลองพิจารณาดูก็ได้

ทุกคน แม้องค์พระพุทธเจ้าของเราก็ตาม ที่ท่านออกมาปฏิบัติ ก็เพื่อจะให้บรรเทากิเลสทั้งหลายนั้น

แต่ว่ามันต้องอยากทำ อยากปฏิบัติ อยากให้มันสงบ และก็ไม่อยากให้มันวุ่นวาย ทั้งสองอย่างนี้ มันเป็นอุปสรรคทั้งนั้น ถ้าเราไม่มีปัญญา ไม่มีความฉลาดในการกระทำอย่างนั้น เพราะว่ามันปนกันอยู่ อยากทั้งสองอย่างนี้มันมีราคาเท่า ๆ กัน

อยากจะพ้นทุกข์มันเป็นกิเลส สำหรับคนไม่มีปัญญา อยากด้วยความโง่ ไม่อยากมันก็เป็นกิเลส เพราะไม่อยากอันนั้นมันประกอบด้วยความโง่เหมือนกัน คือทั้งอยาก ไม่อยาก ปัญญาก็ไม่มี ทั้งสองอย่างนี้ มันเป็นกามสุขัลลิกานุโยโค กับอัตตกิลมถานุโยโค ซึ่งพระพุทธองค์ของเรา ขณะที่พระองค์กำลังทรงปฏิบัติอยู่นั้น ท่านก็หลงใหลในอย่างนี้ ไม่รู้ว่าจะทำอย่างไร ท่านหาอุบายหลายประการ กว่าจะพบของสองสิ่งนี้

ทุกวันนี้เราทั้งหลายก็เหมือนกัน ทุกสิ่งทั้งสองอย่างนี้มันกวนอยู่ เราจึงเข้าสู่ทางไม่ได้ก็เพราะอันนี้ ความเป็นจริงนี้ทุกคนที่มาปฏิบัติ ก็เป็นปุถุชนมาทั้งนั้น ปุถุชนก็เต็มไปด้วยความอยาก ความอยากที่ไม่มีปัญญา อยากด้วยความหลง ไม่อยากมันก็มีโทษเหมือนกัน “ไม่อยาก” มันก็เป็นตัณหา “อยาก” มันก็เป็นตัณหาอีกเหมือนกัน

ทีนี้ นักปฏิบัติยังไม่รู้เรื่องว่า จะเอายังไงกัน เดินไปข้างหน้าก็ไม่ถูก เดินกลับไปข้างหลังก็ไม่ถูก จะหยุดก็หยุดไม่ได้เพราะมันยังอยากอยู่ มันยังหลงอยู่ มีแต่ความอยาก แต่ปัญญาไม่มี มันอยากด้วยความหลง มันก็เป็นตัณหา ถึงแม้ไม่อยาก มันก็เป็นความหลง มันก็เป็นตัณหาเหมือนกันเพราะอะไร? เพราะมันขาดปัญญา

ความเป็นจริงนั้น ธรรมะมันอยู่ตรงนั้นแหละ ตรงความอยากกับความไม่อยากนั่นแหละ แต่เราไม่มีปัญญา ก็พยายามไม่ให้อยากบ้าง เดี๋ยวก็อยากบ้าง อยากให้เป็นอย่างนั้น ไม่อยากให้เป็นอย่างนี้ ความจริงทั้งสองอย่างนี้ หรือทั้งคู่นี้มันตัวเดียวกันทั้งนั้น ไม่ใช่คนละตัว แต่เราไม่รู้เรื่องของมัน

พระพุทธเจ้าของเรา และสาวกทั้งหลายของพระองค์นั้นท่านก็อยากเหมือนกัน แต่ “อยาก” ของท่านนั้น เป็นเพียงอาการของจิตเฉย ๆ หรือ “ไม่อยาก” ของท่าน ก็เป็นเพียงอาการของจิตเฉย ๆ อีกเหมือนกัน มันวูบเดียวเท่านั้น ก็หายไปแล้ว

ดังนั้น ความอยากหรือไม่อยากนี้ มันมีอยู่ตลอดเวลาแต่สำหรับผู้มีปัญญานั้น “อยาก” ก็ไม่มีอุปาทาน “ไม่อยาก” ก็ไม่มีอุปาทาน เป็น “สักแต่ว่า” อยากหรือไม่อยากเท่านั้น ถ้าพูดตามความจริงแล้ว มันก็เป็นแต่ "อาการของจิต" อาการของจิตมันเป็นของมันอย่างนั้นเอง ถ้าเรามาตะครุบมันอยู่ใกล้ ๆ นี่มันก็เห็นชัด

ดังนั้นจึงว่า การพิจารณานั้น ไม่ใช่รู้ไปที่อื่น มันรู้ตรงนี้แหละ เหมือนชาวประมงที่ออกไปทอดแหนั่นแหละ ทอดแหออกไปถูกปลาตัวใหญ่ เจ้าของผู้ทอดแหจะคิดอย่างไร? ก็กลัว กลัวปลาจะออกจากแหไปเสีย เมื่อเป็นเช่นนั้น ใจมันก็ดิ้นรนขึ้นระวังมาก บังคับมาก ตะครุบไปตะครุบมาอยู่นั่นแหละ ประเดี๋ยวปลามันก็ออกจากแหไปเสีย เพราะไปตะครุบมันแรงเกินไป

อย่างนั้นโบราณท่านพูดถึงเรื่องอันนี้ ท่านว่าค่อย ๆ ทำมัน แต่อย่าไปห่างจากมัน นี่คือปฏิปทาของเรา ค่อย ๆ คลำมันไปเรื่อย ๆ อย่างนั้นแหละ

อย่าปล่อยมัน หรือไม่อยากรู้มัน ต้องรู้ ต้องรู้เรื่องของมัน พยายามทำมันไปเรื่อย ๆ ให้เป็นปฏิปทา ขี้เกียจเราก็ทำไม่ขี้เกียจเราก็ทำ เรียกว่าการทำการปฏิบัติ ต้องทำไปเรื่อยๆอย่างนี้

ถ้าหากว่าเราขยัน ขยันเพราะความเชื่อ มันมีศรัทธาแต่ปัญญาไม่มี ถ้าเป็นอย่างนี้ ขยันไป ๆ แล้วมันก็ไม่เกิดผลอะไรขึ้นมากมาย ขยันไปนาน ๆ เข้า แต่มันไม่ถูกทาง มันก็ไม่สงบระงับ ทีนี้ก็จะเกิดความคิดว่า เรานี้บุญน้อยหรือวาสนาน้อย หรือคิดไปว่ามนุษย์ในโลกนี้คงทำไม่ได้หรอก แล้วก็เลยหยุดเลิกทำเลิกปฏิบัติ

ถ้าเกิดความคิดอย่างนี้เมื่อใด ขอให้ระวังให้มาก ให้มีขันติ ความอดทน ให้ทำไปเรื่อย ๆ เหมือนกับเราจับปลาตัวใหญ่ ก็ให้ค่อย ๆ คลำมันไปเรื่อย ๆ ปลามันก็จะไม่ดิ้นแรงค่อย ๆทำไปเรื่อย ๆ ไม่หยุด ไม่ช้าปลาก็จะหมดกำลัง มันก็จับง่าย จับให้ถนัดมือเลย ถ้าเรารีบจนเกินไป ปลามันก็จะหนีดิ้นออกจากแหเท่านั้น

ดังนั้น การปฏิบัตินี้ ถ้าเราพิจารณาตามพื้นเหตุของเรา เช่นว่า เราไม่มีความรู้ในปริยัติ ไม่มีความรู้ในอะไรอื่น ที่จะให้การปฏิบัติมันเกิดผลขึ้น ก็ดูความรู้ที่เป็นพื้นเพเดิมของเรานั่นแหละอันนั้นก็คือ “ธรรมชาติของจิต” นี่เอง มันมีของมันอยู่แล้ว เราจะไปเรียนรู้มัน มันก็มีอยู่ หรือเราจะไม่ไปเรียนรู้มัน มันก็มีอยู่

อย่างที่ท่านพูดว่า พระพุทธเจ้าจะบังเกิดขึ้นก็ตาม หรือไม่บังเกิดขึ้นก็ตาม ธรรมะก็คงมีอยู่อย่างนั้น มันเป็นของมันอยู่อย่างนั้น ไม่พลิกแพลงไปไหน มันเป็นสัจจธรรม

เราไม่เข้าใจสัจจธรรม ก็ไม่รู้ว่าสัจจธรรมเป็นอย่างไร นี้เรียกว่า การพิจารณาในความรู้ของผู้ปฏิบัติที่ไม่มีพื้นปริยัติ

ขอให้ดูจิต พยายามอ่านจิตของเจ้าของ พยายามพูดกับจิตของเจ้าของ มันจึงจะรู้เรื่องของจิต ค่อย ๆ ทำไป ถ้ายังไม่ถึงที่ของมัน มันก็ไปอยู่อย่างนั้น

ครูบาอาจารย์บางท่านบอกว่า ทำไปเรื่อย ๆ อย่าหยุด บางทีเรามาคิด “เออ ทำไปเรื่อย ๆ ถ้าไม่รู้เรื่องของมัน ถ้าทำไม่ถูกที่มัน มันจะรู้อะไร” อย่างนี้เป็นต้น ก็ต้องไปเรื่อย ๆ ก่อน แล้วมันก็จะเกิดความรู้สึกนึกคิดขึ้นในสิ่งที่เราพากเพียรทำนั้น

มันเหมือนกันกับบุรุษที่ไปสีไฟ ได้ฟังท่านบอกว่า เอาไม้ไผ่สองอันมาสีกันเข้าไปเถอะ แล้วจะมีไฟเกิดขึ้น บุรุษนั้นก็จับไม้ไผ่เข้าสองอัน สีกันเข้า แต่ใจร้อน สีไปได้หน่อย ก็อยากให้มันเป็นไฟ ใจก็เร่งอยู่เรื่อย ให้เป็นไฟเร็วๆ แต่ไฟก็ไม่เกิดสักที บุรุษนั้นก็เกิดความขี้เกียจ แล้วก็หยุดพัก แล้วจึงลองสีอีกนิด แล้วก็หยุดพัก ความร้อนที่พอมีอยู่บ้าง ก็หายไปล่ะซิ เพราะความร้อนมันไม่ติดต่อกัน

ถ้าทำไปเรื่อยๆอย่างนี้ เหนื่อยก็หยุด มีแต่เหนื่อยอย่างเดียวก็พอได้ แต่มีขี้เกียจปนเข้าด้วย เลยไปกันใหญ่ แล้วบุรุษนั้นก็หาว่าไฟไม่มี ไม่เอาไฟ ก็ทิ้ง เลิก ไม่สีอีก แล้วก็ไปเที่ยวประกาศว่า ไฟไม่มี ทำอย่างนี้ไม่ได้ ไม่มีไฟหรอก เขาได้ลองทำแล้ว

ก็จริงเหมือนกันที่ได้ทำแล้ว แต่ทำยังไม่ถึงจุดของมันคือความร้อนยังไม่สมดุลกัน ไฟมันก็เกิดขึ้นไม่ได้ ทั้งที่ความจริงไฟมันก็มีอยู่ อย่างนี้ก็เกิดความท้อแท้ขึ้นในใจของผู้ปฏิบัตินั้น ก็ละอันนี้ไปทำอันโน้นเรื่อยไป อันนี้ฉันใดก็ฉันนั้น

การปฏิบัตินั้น ปฏิบัติทางกายทางใจทั้งสองอย่าง มันต้องพร้อมกัน เพราะอะไร? เพราะพื้นเพมันเป็นคนมีกิเลสทั้งนั้น พระพุทธเจ้าก่อนที่จะเป็นพระพุทธเจ้า ท่านก็มีกิเลสแต่ท่านมีปัญญามากหลาย พระอรหันต์ก็เหมือนกัน เมื่อยังเป็นปุถุชนอยู่ ก็เหมือนกับเรา

เมื่อความอยากเกิดขึ้นมา เราก็ไม่รู้จัก เมื่อความไม่อยากเกิดขึ้นมา เราก็ไม่รู้จัก บางทีก็ร้อนใจ บางทีก็ดีใจ ถ้าใจเราไม่อยาก ก็ดีใจแบบหนึ่ง และวุ่นวายอีกแบบหนึ่ง ถ้าใจเราอยาก มันก็วุ่นวายอย่างหนึ่ง และดีใจอย่างหนึ่ง มันประสมประเสกันอยู่อย่างนี้

อันนี้คือปฏิปทาของผู้ปฏิบัติเรา

Marty's Bent

via levelsio

Over the weekend, prolific vibe coder levelsio took to X to complain about the state of housing affordability across Europe. Something that I was very happy to see considering the fact that there is a massive real estate affordability crisis across much of the world and it is important that people who are respected and have platforms speak out when they identify the problem as well. More eyes and focus on the problem is how something begins to get solved.

With that being said, I think levelsio is missing the forest for the trees by blaming institutionalized NIMBYism, burdensome regulations and governments hoarding land that should instead be given to developers to produce more housing supply. I quote tweeted this particular tweet on the subject from levelsio and wanted to take some time today to republish those thoughts here and expand on the topic.

It’s almost as if real estate is being used as a store of value asset instead of the consumable good that it is.

What @levelsio is observing here is called a “monetary premium”. A monetary premium is the value added on top of the consumable/aesthetic/location value of real estate.

This monetary premium exist because central banks and governments have distorted the market for money and people are forced to push value into assets that are scarce relative to dollars. Over the last 50 years real estate has been one of the relatively scarce assets of choice.

The housing affordability crisis is a negative externality of the market reaction to the corruption of money. It can only be fixed by re-introducing hard money into the economy that enables people to store value reliably. If that emerges they won’t have to store value in real estate, the monetary premium of real estate will dissolve and prices will correct to their proper valuations.

This is one of the problems that bitcoin solves.

It’s still early yet, but more and more people are recognizing the utility provided by a neutral reserve asset that can’t be manipulated by central planners. At scale, the effect on assets that have accumulated a monetary premium over decades will be material. All of these assets are significantly overvalued and their monetary premium are leaking into bitcoin.

Put another way, "It's the money, stupid." Now, this isn't to say that the supply of housing in certain areas being artificially restricted isn't having an effect on the price of housing. This is certainly true, especially in cities like San Francisco where there is a relatively strong demand because of the economic density of the area and the desire of many high agency and productive people to live there. But I would put forth that the monetary premium is still the bigger problem and no amount of de-regulation to enable the supply of housing to increase will solve the affordability crisis in the long-run. The only way to get to the root of this specific problem is via bitcoin's mainstream adoption as an apolitical uncontrollable asset with completely idiosyncratic risks when compared to any individual asset class.

Let's say the government did ease up regulations and local NIMBY sympathetics were shoved in a corner to allow new units to be built. This doesn't solve the problem in the short-run because there is a time-delay between when regulations are lifted and when new supply actually makes it to market. In the interim, governments and central banks are inevitably going to go further into debt and be forced to print money to monetize that debt. This will exacerbate inflation and even if new real estate units are brought to market, the builders/owners of those properties will likely have to demand elevated prices to attempt to keep up with inflation.

This also does nothing to solve the problem of real income and wage growth, which are significantly lagging real inflation. Even if prices came down because of a surge in supply, could the Common Man afford a down payment on the property? I'd be shocked if this was the case. And since it's likely not the case the only way to get people into these houses as "owners" would be to offer them zero-down financing, which makes people feel richer than they actually are and leads them to make financially ruinous decisions.

It's the money, stupid. People need a way to save so that they can buy in the first place. Fiat currency doesn't allow this and the only people who can save effectively are those who make enough money to funnel into substitute store of value assets like real estate.

As it stands today, the price-to-income ratio of real estate is 5.0x and the price-t0-rent index is 1.36. Up from 3.3x and 1.14x respectively where the metrics sat in the year 2000. The growth in these ratios is driven predominately via their monetary premium.

And guess what, it's about to get much worse. Donald Trump, Treasury Secretary Scott Bessent and Elon Musk have all signaled that the plan moving forward is to attempt to drive growth and productivity as high as possible while also letting deficits and the debt increase unabated, which means that inflation is likely to continue unabated and potentially increase.

It might make sense to get some bitcoin if that is the case.

"Whale in the Pool" Risk That Could Destroy MSTY Investors

Jessy Gilger raised serious concerns about MSTY and similar derivative products that promise eye-popping yields. He pointed to the COVID crash where gold mining ETFs using derivatives collapsed 95% and never recovered, despite gold itself performing well. Jessy noted that while his team calculated reasonable MicroStrategy covered call yields of 16-22%, MSTY advertises 120% annualized distributions - a red flag that suggests these aren't sustainable dividends from profits, but potentially just returning investors' own capital.

"If a whale pees in the pool, everyone is affected." - Jessy Gilger

Jessy explained that when large investors need to exit these pooled products during market stress, they must sell derivative positions into illiquid markets with no buyers, potentially triggering catastrophic losses for all participants. His solution? Private pools through separately managed accounts that achieve similar income goals without the contagion risk of being trapped with panicking whales.

Block’s hardware wallet sparks debate between security and borderline compromises.

The debate ignited after Jack Dorsey publicly supported the superiority of “seedless” wallets over traditional solutions on X.

seedless is safer https://t.co/MvjmFcQE8k

— jack (@jack) May 27, 2025

The Twitter co-founder and Block CEO sustained this by promoting Bitkey, a company that completely eliminates seed phrases, aiming to simplify the user experience and improve security through different recovery options.

The Bitkey model

Bitkey represents a different solution compared to the traditional approach to bitcoin custody. Instead of relying on a single seed phrase, the system implements a 2-of-3 multisig scheme that distributes security across three distinct keys:

• Hardware key: protected by biometric fingerprint on the physical device;
• Mobile key: stored in the smartphone app;
• Server key: managed by Block’s servers.

Any transaction requires two of the three signatures, eliminating the single point of failure represented by traditional seed phrases, the company claims. In its official documents, Bitkey explains how this approach, according to the company, offers three different recovery paths: phone loss, hardware loss, or loss of both through “Trusted Contacts,” pre-set trusted people who can help the user regain wallet access without being able to see the balance or control the private keys.

The seed phrase criticism

For the Bitkey team, the seed phrase paradoxically represents the weakest link in the Bitcoin security chain. While private keys are “exceptionally secure” within the hardware – “designed for security, isolated from networks, physically reinforced” – the seed phrase is “plain text, readable, physically vulnerable,” the company states.

Bitkey developers argue that the industry has “offloaded the most complex part of the security model onto individuals least equipped to handle it.”

System limits and dependencies

However, Bitkey’s simplicity comes at a price. The system introduces a dependency on Block for optimal multisig functionality. Although users always maintain the ability to move funds using the two keys in their possession, recovery procedures and many advanced features require collaboration from the company’s servers.

This architecture presents limitations in terms of flexibility: users cannot use Bitkey with other mobile applications, cannot import the wallet into alternative solutions, and do not have direct access to seed phrases for traditional backup operations.

One of the most frequent criticisms concerns the absence of a screen on the hardware device. Unlike traditional hardware wallets that allow direct verification of destination addresses and transaction amounts on the device display, Bitkey forces users to rely exclusively on the mobile app for these details. This design choice introduces what critics define as a “blind signing risk”: if the mobile app were compromised by malware, users could unknowingly authorize altered transactions without the possibility of independent verification.

Community criticism

Dorsey’s post sparked contrasting reactions in the community. The most orthodox bitcoiners mainly contest two aspects:

• third-party dependency: despite Bitkey maintaining the “self-custody” label, the need to rely on Block’s servers for many operations contradicts the autonomy principles that many bitcoiners consider fundamental;
• loss of technical control: the inability to directly manage the seed phrase or use the device in customized multisig configurations limits the user’s technical sovereignty.

Some users have criticized Block’s hardware wallet. User bamskki highlighted how “the lack of a screen forces users to rely on the app for transaction details. Unlike traditional hardware wallets with screens, Bitkey users cannot verify transactions independently. Users must trust the app as the source of truth.”

Even more critical was user nakadai_mon, who ironized about Dorsey’s strategy writing: “It would be a shame if I influenced you to abandon the seed and locked you into my ecosystem so I can surveil you, sell and share your personal data with government authorities and deny you service.”

Dorsey responded directly to both criticisms. To bamskki he replied:

it's a start, not our end. we will iterate the product like everything else.

— jack (@jack) May 28, 2025

More articulated was his response to nakadai_mon:

we are working on much of the privacy aspects (launching soon). and you don't have to use our 3rd key. that's where some of the restrictions come in. working to figure out how to allow folks to create their own trusted 3rd party as well. but all of this is designed to get people…

— jack (@jack) May 28, 2025

However, privacy concerns are not unfounded. Bitkey’s own documentation clarifies that “because we maintain this key, we are able to identify transaction data on the blockchain related to your Bitkey” and that “this information is collected when you transfer bitcoin to or from your Bitkey.”

Additionally, Block declares using automated decision-making systems, without direct staff involvement, to manage some activities that have legal effects on users. Among these, the application of sanctions restrictions: the system is programmed to automatically prevent the purchase and use of Bitkey by people or countries subject to international sanctions. Finally, the privacy policy specifies that users’ personal data can be shared with law enforcement, government agencies, officials, or authorized third parties in the presence of a warrant, court order, or other legal obligation. Block reserves the right to disclose this information whenever it deems necessary to comply with regulations, legal proceedings, or government requests.

Hardware security and compromises

From a hardware security perspective, Bitkey implements advanced protections including unique device identifiers, secure boot, and anti-tamper technologies. In case the device were compromised, an attacker would still need to access a second key to steal funds.

According to Dorsey’s statements, Bitkey represents an attempt to make self-custody accessible to a broader audience. The company’s roadmap promises improvements in terms of privacy, security, and usability.

A few months ago, a nostrich was switching from iOS to Android and asked for suggestions for #Nostr apps to try out. nostr:npub18ams6ewn5aj2n3wt2qawzglx9mr4nzksxhvrdc4gzrecw7n5tvjqctp424 offered the following as his response:

nostr:nevent1qvzqqqqqqypzq0mhp4ja8fmy48zuk5p6uy37vtk8tx9dqdwcxm32sy8nsaa8gkeyqydhwumn8ghj7un9d3shjtnwdaehgunsd3jkyuewvdhk6tcpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhszythwden5te0dehhxarj9emkjmn99uqzpwwts6n28eyvjpcwvu5akkwu85eg92dpvgw7cgmpe4czdadqvnv984rl0z

Yes. #Android users are fortunate to have some powerful Nostr apps and tools at our disposal that simply have no comparison over on the iOS side. However, a tool is only as good as the knowledge of the user, who must have an understanding of how best to wield it for maximum effect. This fact was immediately evidenced by replies to Derek asking, "What is the use case for Citrine?" and "This is the first time I'm hearing about Citrine and Pokey. Can you give me links for those?"

Well, consider this tutorial your Nostr starter-kit for Android. We'll go over installing and setting up Amber, Amethyst, Citrine, and Pokey, and as a bonus we'll be throwing in the Zapstore and Coinos to boot. We will assume no previous experience with any of the above, so if you already know all about one or more of these apps, you can feel free to skip that tutorial.

So many apps...

You may be wondering, "Why do I need so many apps to use Nostr?" That's perfectly valid, and the honest answer is, you don't. You can absolutely just install a Nostr client from the Play Store, have it generate your Nostr identity for you, and stick with the default relays already set up in that app. You don't even need to connect a wallet, if you don't want to. However, you won't experience all that Nostr has to offer if that is as far as you go, any more than you would experience all that Italian cuisine has to offer if you only ever try spaghetti.

Nostr is not just one app that does one thing, like Facebook, Twitter, or TikTok. It is an entire ecosystem of applications that are all built on top of a protocol that allows them to be interoperable. This set of tools will help you make the most out of that interoperability, which you will never get from any of the big-tech social platforms. It will provide a solid foundation for you to build upon as you explore more and more of what Nostr has to offer.

So what do these apps do?

Fundamental to everything you do on Nostr is the need to cryptographically sign with your private key. If you aren't sure what that means, just imagine that you had to enter your password every time you hit the "like" button on Facebook, or every time you commented on the latest dank meme. That would get old really fast, right? That's effectively what Nostr requires, but on steroids.

To keep this from being something you manually have to do every 5 seconds when you post a note, react to someone else's note, or add a comment, Nostr apps can store your private key and use it to sign behind the scenes for you. This is very convenient, but it means you are trusting that app to not do anything with your private key that you don't want it to. You are also trusting it to not leak your private key, because anyone who gets their hands on it will be able to post as you, see your private messages, and effectively be you on Nostr. The more apps you give your private key to, the greater your risk that it will eventually be compromised.

Enter #Amber, an application that will store your private key in only one app, and all other compatible Nostr apps can communicate with it to request a signature, without giving any of those other apps access to your private key.

Most Nostr apps for Android now support logging in and signing with Amber, and you can even use it to log into apps on other devices, such as some of the web apps you use on your PC. It's an incredible tool given to us by nostr:npub1w4uswmv6lu9yel005l3qgheysmr7tk9uvwluddznju3nuxalevvs2d0jr5, and only available for Android users. Those on iPhone are incredibly jealous that they don't have anything comparable, yet.

Speaking of nostr:npub1w4uswmv6lu9yel005l3qgheysmr7tk9uvwluddznju3nuxalevvs2d0jr5, the next app is also one of his making.

All Nostr data is stored on relays, which are very simple servers that Nostr apps read notes from and write notes to. In most forms of social media, it can be a pain to get your own data out to keep a backup. That's not the case on Nostr. Anyone can run their own relay, either for the sake of backing up their personal notes, or for others to post their notes to, as well.

Since Nostr notes take up very little space, you can actually run a relay on your phone. I have been on Nostr for almost 2 and a half years, and I have 25,000+ notes of various kinds on my relay, and a backup of that full database is just 24MB on my phone's storage.

Having that backup can save your bacon if you try out a new Nostr client and it doesn't find your existing follow list for some reason, so it writes a new one and you suddenly lose all of the people you were following. Just pop into your #Citrine relay, confirm it still has your correct follow list or import it from a recent backup, then have Citrine restore it. Done.

Additionally, there are things you may want to only save to a relay you control, such as draft messages that you aren't ready to post publicly, or eCash tokens, which can actually be saved to Nostr relays now. Citrine can also be used with Amber for signing into certain Nostr applications that use a relay to communicate with Amber.

If you are really adventurous, you can also expose Citrine over Tor to be used as an outbox relay, or used for peer-to-peer private messaging, but that is far more involved than the scope of this tutorial series.

You can't get far in Nostr without a solid and reliable client to interact with. #Amethyst is the client we will be using for this tutorial because there simply isn't another Android client that comes close, so far. Moreover, it can be a great client for new users to get started on, and yet it has a ton of features for power-users to take advantage of as well.

There are plenty of other good clients to check out over time, such as Coracle, YakiHonne, Voyage, Olas, Flotilla and others, but I keep coming back to Amethyst, and by the time you finish this tutorial, I think you'll see why. nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z and others who have contributed to Amethyst have really built something special in this client, and it just keeps improving with every update that's shipped.

Most social media apps have some form of push notifications, and some Nostr apps do, too. Where the issue comes in is that Nostr apps are all interoperable. If you have more than one application, you're going to have both of them notifying you. Nostr users are known for having five or more Nostr apps that they use regularly. If all of them had notifications turned on, it would be a nightmare. So maybe you limit it to only one of your Nostr apps having notifications turned on, but then you are pretty well locked-in to opening that particular app when you tap on the notification.

Pokey, by nostr:npub1v3tgrwwsv7c6xckyhm5dmluc05jxd4yeqhpxew87chn0kua0tjzqc6yvjh, solves this issue, allowing you to turn notifications off for all of your Nostr apps, and have Pokey handle them all for you. Then, when you tap on a Pokey notification, you can choose which Nostr app to open it in.

Pokey also gives you control over the types of things you want to be notified about. Maybe you don't care about reactions, and you just want to know about zaps, comments, and direct messages. Pokey has you covered. It even supports multiple accounts, so you can get notifications for all the npubs you control.

One of the most unique and incredibly fun aspects of Nostr is the ability to send and receive #zaps. Instead of merely giving someone a 👍️ when you like something they said, you can actually send them real value in the form of sats, small portions of a Bitcoin. There is nothing quite like the experience of receiving your first zap and realizing that someone valued what you said enough to send you a small amount (and sometimes not so small) of #Bitcoin, the best money mankind has ever known.

To be able to have that experience, though, you are going to need a wallet that can send and receive zaps, and preferably one that is easy to connect to Nostr applications. My current preference for that is Alby Hub, but not everyone wants to deal with all that comes along with running a #Lightning node. That being the case, I have opted to use nostr:npub1h2qfjpnxau9k7ja9qkf50043xfpfy8j5v60xsqryef64y44puwnq28w8ch for this tutorial, because they offer one of the easiest wallets to set up, and it connects to most Nostr apps by just copy/pasting a connection string from the settings in the wallet into the settings in your Nostr app of choice.

Additionally, even though #Coinos is a custodial wallet, you can have it automatically transfer any #sats over a specified threshold to a separate wallet, allowing you to mitigate the custodial risk without needing to keep an eye on your balance and make the transfer manually.

Most of us on Android are used to getting all of our mobile apps from one souce: the Google Play Store. That's not possible for this tutorial series. Only one of the apps mentioned above is available in Google's permissioned playground. However, on Android we have the advantage of being able to install whatever we want on our device, just by popping into our settings and flipping a toggle. Indeed, thumbing our noses at big-tech is at the heart of the Nostr ethos, so why would we make ourselves beholden to Google for installing Nostr apps?

The nostr:npub10r8xl2njyepcw2zwv3a6dyufj4e4ajx86hz6v4ehu4gnpupxxp7stjt2p8 is an alternative app store made by nostr:npub1wf4pufsucer5va8g9p0rj5dnhvfeh6d8w0g6eayaep5dhps6rsgs43dgh9 as a resource for all sorts of open-source apps, but especially Nostr apps. What is more, you can log in with Amber, connect a wallet like Coinos, and support the developers of your favorite Nostr apps directly within the #Zapstore by zapping their app releases.

One of the biggest features of the Zapstore is the fact that developers can cryptographically sign their app releases using their Nostr keys, so you know that the app you are downloading is the one they actually released and hasn't been altered in any way. The Zapstore will warn you and won't let you install the app if the signature is invalid.

Getting Started

Since the Zapstore will be the source we use for installing most of the other apps mentioned, we will start with installing the Zapstore.

We will then use the Zapstore to install Amber and set it up with our Nostr account, either by creating a new private key, or by importing one we already have. We'll also use it to log into the Zapstore.

Next, we will install Amethyst from the Zapstore and log into it via Amber.

After this, we will install Citrine from the Zapstore and add it as a local relay on Amethyst.

Because we want to be able to send and receive zaps, we will set up a wallet with CoinOS and connect it to Amethyst and the Zapstore using Nostr Wallet Connect.

Finally, we will install Pokey using the Zapstore, log into it using Amber, and set up the notifications we want to receive.

By the time you are done with this series, you will have a great head-start on your Nostr journey compared to muddling through it all on your own. Moreover, you will have developed a familiarity with how things generally work on Nostr that can be applied to other apps you try out in the future.

I spent Memorial Day swimming in the local river - something I try to do at least four times a week. It’s the best form of exercise imo, but it’s more than that. Swimming against the tide, feeling the water move around me... there’s something about it that keeps me grounded. Nature at her peak.

Today I brought my X-Pro2 with the 1959 Leica Summaron 35mm f/2.8. I'm still testing the lens wide open to get a feel for its character. My subject this time: the light playing on the ripples and waves.

While I was shooting, a kid randomly ran up to me and started telling me something about what he got for his dad while fishing, or something - I didn’t quite hear him - and then he asked what I was looking at. I told him, “The ripples. The way the light is refracting.” I had him sit exactly where I was so he could see it too.

He lit up. You could tell no one had ever pointed something like that out to him before. In that moment, I felt like maybe I was able to plant a little seed - a new way of seeing.

This is what I was looking at.

Why Bitcoin Matters

Saving is the greatest discovery in human history

ກ່ອນທີ່ມະນຸດຈະຮຽນຮູ້ການເກັບອອມ, ພວກເຮົາເປັນພຽງແຕ່ສັດທີ່ມີຊີວິດຢູ່ແບບວັນຕໍ່ວັນ. ການປະຢັດແມ່ນສິ່ງທີ່ເຮັດໃຫ້ມະນຸດແຕກຕ່າງຈາກສັດອື່ນ — ຄວາມສາມາດໃນການຄິດກ່ຽວກັບອະນາຄົດ ແລະ ເກັບໄວ້ສຳລັບມື້ຫຼັງ.

Saving created civilization itself

ບໍ່ມີການເກັບອອມ, ບໍ່ມີການສ້າງເມືອງ, ບໍ່ມີວິທະຍາສາດ, ບໍ່ມີສິລະປະ. ທຸກສິ່ງທີ່ເຮົາເອີ້ນວ່າ "ຄວາມກ້າວໜ້າ" ແມ່ນມາຈາກຄວາມສາມາດໃນການຮູ້ຈັກເກັບອອມ.

Money is the greatest creation in human history

ມັນເປັນເຄື່ອງມືທີ່ເຮັດໃຫ້ອາລະຍະທຳມະນຸດກ້າວໜ້າມາເຖິງທຸກມື້ນີ້ ເງິນ ເປັນເຄື່ອງມືທີ່ດີທີ່ສຸດທີ່ມະນຸດໃຊ້ໃນການເກັບອອມ.

Bitcoin is the best money ever created

ມັນແມ່ນເງິນທີ່ສົມບູນແບບທີ່ສຸດທີ່ມະນຸດເຄີຍສ້າງຂຶ້ນມາ. ບໍ່ມີໃຜສາມາດ ຄວບຄຸມ, ຈັດການ, ທຳລາຍ ແລະ ມີຈຳກັດຢ່າງແທ້ຈິງ ຄືກັບເວລາໃນຊີວິດ.

Bitcoin ຄືກັບ black hole

ທີ່ຈະດູດເອົາມູນຄ່າທັງໝົດຈາກລະບົບການເງິນທີ່ເສຍຫາຍມັນຈະດູດເອົາຄວາມໝັ້ນຄົງແລະມູນຄ່າມາສູ່ຕົວມັນເອງ. ທຸກສິ່ງທີ່ມີມູນຄ່າຈະໄຫຼເຂົ້າສູ່ Bitcoin ໃນທີ່ສຸດ.

Bitcoin ຄືກັບສາດສະໜາພຸດທີ່ຄົ້ນພົບຄວາມຈິງ

ມັນເຮັດໃຫ້ເຂົ້າໃຈຕົ້ນຕໍບັນຫາຂອງລະບົບການເງິນປະຈຸບັນ ແລະ ເກີດເປັນບັນຫາຫລາຍໆຢ່າງໃນສັງຄົມ ດັ່ງກັບພະພຸດທະເຈົ້າທີ່ເຂົ້າໃຈທຸກ ແລະ ເຫດຂອງການເກີດທຸກ.

Bitcoin ຄືອິດສະຫຼະພາບ

ເງິນຄືອຳນາດ, ເງິນຄືສິ່ງຄວບຄຸມພຶດຕິກຳຂອງມະນຸດ ເມື່ອເຮົາມີເງິນທີ່ຮັກສາມູນຄ່າໄດ້ ແລະ ຄວບຄຸມບໍ່ໄດ້ ຈຶ່ງຈະມີຄວາມອິດສະຫຼະທາງຄວາມຄິດ, ການສະແດງອອກ, ແລະ ອຳນາດໃນການເລືອກ.

ຫນີ້ສິນທີ່ມະນຸດສ້າງຂຶ້ນໃນປະຈຸບັນນີ້ ໃຊ້ເວລາອີກພັນປີກໍ່ໄຊ້ຫນີ້ບໍ່ໝົດ

ມັນບໍ່ມີທາງອອກ ແລະ ກຳລັງມຸ່ງໜ້າສູ່ການລົ່ມສະລາຍຢ່າງຮ້າຍແຮງ. Bitcoin ຄືແສງສະຫວ່າງທີ່ຈະຊ່ວຍປ້ອງກັນບໍ່ໃຫ້ມະນຸດເຂົ້າສູ່ຍຸກມືດມົວອີກຄັ້ງ.

Bitcoin cannot steal your time

ມັນບໍ່ສາມາດຖືກສ້າງຂຶ້ນຈາກຄວາມຫວ່າງເປົ່າ. ທຸກ Bitcoin ຕ້ອງໃຊ້ພະລັງງານແລະເວລາທີ່ແທ້ຈິງໃນການສ້າງ.

Bitcoin ຄືປະກັນໄພທີ່ປ້ອງກັນການບໍລິຫານທີ່ຜິດພາດ

ມັນຊ່ວຍປ້ອງກັນຄວາມເສື່ອມໂຊມຂອງເງິນຕາ, ເສດຖະກິດທີ່ຕົກຕ່ຳ ແລະ ນະໂຍບາຍທີ່ຜິດພາດ, Bitcoin ຈະປົກປ້ອງຄຸນຄ່າຂອງເຈົ້າ.

Bitcoin is going to absorb the world's value

ໃນທີ່ສຸດ, Bitcoin ຈະກາຍເປັນທີ່ເກັບຮັກສາມູນຄ່າຂອງໂລກທັງໝົດ. ມັນຈະດູດເອົາຄວາມມັ່ງຄັ່ງຈາກທຸກຊັບສິນ, ທຸກລາຄາ, ແລະທຸກການລົງທຶນ.

Exit The Matrix

ພວກເຮົາອາໄສຢູ່ໃນ Matrix ທາງດ້ານການເງິນ. ທຸກໆມື້ພວກເຮົາຕື່ນຂຶ້ນມາແລະໄປເຮັດວຽກ, ຄິດວ່າເຮົາກຳລັງສ້າງອະນາຄົດໃຫ້ຕົວເອງ. ແຕ່ຄວາມຈິງແລ້ວ, ພວກເຮົາພຽງແຕ່ກຳລັງໃຫ້ພະລັງງານແກ່ລະບົບທີ່ຂູດເອົາຄຸນຄ່າຈາກພວກເຮົາທຸກວິນາທີ. Bitcoin is the red pill — ມັນຈະເປີດຕາໃຫ້ເຈົ້າເຫັນຄວາມຈິງຂອງໂລກການເງິນ. Central banks are the architects of this Matrix — ພວກເຂົາສ້າງເງິນຈາກຄວາມຫວ່າງເປົ່າ, ແລະພວກເຮົາຕ້ອງເຮັດວຽກໜັກເພື່ອໄດ້ມັນມາ.

ລະບົບການສຶກສາໄດ້ຫຼອກລວງເຮົາຢ່າງໃຫຍ່ຫຼວງ. ພວກເຂົາສອນໃຫ້ເຮົາເຮັດວຽກເພື່ອຫາເງິນ, ແຕ່ບໍ່ເຄີຍສອນວ່າເງິນແມ່ນຫຍັງ. ເຮົາໃຊ້ເວລາ 12-16 ປີໃນໂຮງຮຽນ, ຫຼັງຈາກນັ້ນໃຊ້ເວລາທັງຊີວິດເພື່ອຫາເງິນ, ແຕ່ບໍ່ເຄີຍຮູ້ຈັກວ່າມັນແມ່ນຫຍັງ, ໃຜສ້າງ, ແລະເປັນຫຍັງມັນມີຄຸນຄ່າ.This is the biggest scam in human history ພວກເຮົາຖືກສອນໃຫ້ເປັນທາດຂອງລະບົບ, ແຕ່ບໍ່ໄດ້ຮັບການສອນໃຫ້ເຂົ້າໃຈລະບົບ.

The Bitcoin standard will end war

ເມື່ອບໍ່ສາມາດພິມເງິນເພື່ອສົງຄາມແລ້ວ, ສົງຄາມຈະກາຍເປັນສິ່ງທີ່ແພງເກີນໄປ.

ພວກເຮົາກຳລັງເຂົ້າສູ່ຍຸກ Bitcoin Renaissance

ຍຸກແຫ່ງການຟື້ນຟູທາງດ້ານການເງິນແລະປັນຍາ. Bitcoin is creating a new class of humans ຄົນທີ່ເຂົ້າໃຈ ແລະ ຖື Bitcoin ຈະກາຍເປັນຊົນຊັ້ນໃໝ່ທີ່ມີອິດສະຫຼະພາບຢ່າງແທ້ຈິງ.

The Path to Financial Truth

Follow the money trail ແລະເຈົ້າຈະເຫັນຄວາມຈິງ:

• ໃຜຄວບຄຸມການພິມເງິນ?
• ເປັນຫຍັງລາຄາສິນຄ້າຂຶ້ນສູງຂຶ້ນເລື້ອຍໆ?
• ເປັນຫຍັງຄົນທຸກທຸກກວ່າເກົ່າ ແລະຄົນຮັ່ງມີຮັ່ງມີກວ່າເກົ່າ?

ຄຳຕອບທັງໝົດແມ່ນຢູ່ໃນການທຳຄວາມເຂົ້າໃຈເລື່ອງເງິນ ແລະ Bitcoin.

ການສຶກສາ Bitcoin ບໍ່ແມ່ນພຽງແຕ່ການລົງທຶນ — ມັນແມ່ນການເຂົ້າໃຈອະນາຄົດຂອງເງິນຕາ ແລະ ສັງຄົມມະນຸດ.

Don't just work for money. Understand money. Study Bitcoin.

ຖ້າເຈົ້າບໍ່ເຂົ້າໃຈເງິນ, ເຈົ້າຈະເປັນທາດຂອງລະບົບຕະຫຼອດໄປ. ຖ້າເຈົ້າເຂົ້າໃຈ Bitcoin, ເຈົ້າຈະໄດ້ຮັບອິດສະຫຼະພາບ.

Markdown + X, Y, Z is a problem, but Markdown + N can fix that.
Where N = any type of Nostr event.

Whatever Markup language you choose, people will be referencing other Nostr events in it all the time. Since apps have to find ways to display those events (or the links to them) anyway, we mights as well use that as an opportunity.

Why can't Tables, for example, be embedded Nostr events?

Switching from Markdown to Asciidocs (because it has tables and some more technical stuff) still doesn’t make Tables a great experience. On mobile, Tables are notoriously hard to display in a useful way. It depends on the use case, size of the table, etc….

Creators need guarantees on these things being displayed the way they intended.
There’s a reason why most authors just embed pictures of tables instead. It has little to do with Markdown not really supporting tables and more with them ensuring readability and appropriate styling.

So what if you enhance Markdown not only with embedded Nostr Events but also with something like Hypernotes Widgets that serve as a preview/display for those Nostr Events?

That way: - you are still using the most simple and popular markup language - devs “only” have to implement one extra thing (Hypernotes) that handles all the complexity and extensibility from there - authors can create articles and wiki entries with interactive elements in them, can have the guarantee that they display properly, can use any styling that suits them, etc… - the worst case scenario of reading it in a random crappy app still displays the link to the event (including it's explanatory metadata)

Imagine custom interactive graphs, polls, media players, products, … embedded in articles BUT limited to the Nostr-verse for all interaction and data fetching.

(this article will be updated with UI prototypes and further thoughts)

Bitcoin surpasses gold in the United States: 50 million holders and a dominant role in the global market.

According to a new report by River, for the first time in history, the number of Americans owning bitcoin has surpassed that of gold holders. The analysis reveals that approximately 50 million U.S. citizens currently own the cryptocurrency, while gold owners number 37 million. In fact, 14.3% of Americans own bitcoin, the highest percentage of holders worldwide.

Source: River

The report highlights that 40% of all Bitcoin-focused companies are based in the United States, consolidating America’s dominant position in the sector. Additionally, 40.5% of Bitcoin holders are men aged 31 to 35, followed by 35.9% of men aged 41 to 45. In contrast, only 13.4% of holders are women.

Source: River

Notably, U.S. companies hold 94.8% of all bitcoins owned by publicly traded companies worldwide. According to the report, recent regulatory changes in the U.S. have made the asset more accessible through financial products such as spot ETFs.

The document also shows that American investors increasingly view the cryptocurrency as protection against fiscal instability and inflation, appreciating its limited supply and decentralized governance model.

For River, Bitcoin offers significant practical advantages over gold in the modern digital era. Its ease of custody, cross-border transfer, and liquidity make the cryptocurrency an attractive option for both individual and institutional investors, the report suggests.

Today I pause — not to celebrate, but to remember.\ Memorial Day is a reminder that freedom always comes at a cost. Not theoretical. Not digital. Real. Blood-bought. Passed down.

I didn’t earn the liberties I have. Someone else paid for them.\ The least I can do is steward them well — in how I live, build, and speak.

Tomorrow, I head to Bitcoin 2025.\ I go not just as a Bitcoiner, but as someone who believes Bitcoin, when rightly understood, calls us back to truth, cost, and accountability.\ Not magic internet money. Not another tech trend.\ But a reckoning.

So I walk into this week with both gratitude and resolve:

• Grateful for those who gave their lives.

• Grateful for the freedom to write, build, and think out loud.

• Resolved to use that freedom wisely — and to build systems that don't require bloodshed to sustain them.

Let’s build what lasts.\ Let’s remember what was paid.\ Let’s walk into Bitcoin 2025 with clear eyes and full hearts.

Why Trading Matters (And Why It’s Not a Zero-Sum Game)

There’s a common belief — even in some Bitcoin circles — that short-term trading is just gambling. That it’s a zero-sum game where one trader’s win is another’s loss.

I get it. The noise is real. So is the wreckage from over-leveraged bets and mindless speculation.

But that’s not the whole story.

Recently, someone I worked with in 2023 and 2024 — a former mortgage broker — invited me to join an “investment club” that sends buy/sell signals through WhatsApp.\ Just follow the messages. Don’t think. Don’t learn. Just click and hope.

That’s not trading.\ That’s waiting on an oracle and outsourcing your judgment. It’s faith in hype, not process. It’s anti-skill.

Another friend told me my approach — aiming for consistent, small intraday gains — sounded boring. But here’s what I told him:

If I trade a $100 stock ten times in a day for a $1–2 gain each time, I’ve made the same as someone waiting around for that one 10% spike.\ But I’ve done it with discipline, risk control, and real engagement. That’s not boring. That’s working.

These days, I only trade equities. No crypto. No forex.

Why? Because equities are productive assets tied to real businesses in a real economy.\ They aren’t my end goal — Bitcoin is.\ But equities offer a stable, regulated environment to extract short-term gains without feeding the casino culture of leveraged altcoins or hypervolatile FX pairs.

And forex? You're just trading one melting ice cube for another — flipping between fiat currencies that are backed by nothing but promises and policies.\ It's like playing musical chairs with pieces of paper while the music gets faster.\ I’ve done it. I understand it. But it no longer feels congruent with my Bitcoin ethos.

It’s not about purity. It’s about alignment.\ If I’m going to trade, I want the process to reflect the same principles that drew me to Bitcoin: transparency, discipline, and long-term thinking.

Real trading is:

• Dynamic, not zero-sum.\ While some instruments are win/lose, markets as a whole reward liquidity, attention, and adaptability. Traders contribute to price discovery.

• A funding mechanism for conviction.\ I don’t trade just to make money — I trade to build. My equity gains fund my Bitcoin stacking, my open-source work, my writing, my peace of mind.

• A craft, not a shortcut.\ The edge is earned. Over time. In silence. With scars.

I’m not here to follow someone’s signals.\ And I’m not chasing that one moonshot.

This is daily work.\ This is Proof of Work.

Postscript:\ This week? No red days. A green week — around $300.\ Not a huge number. And that’s okay.\ Because I wasn’t just trading.

I was writing. Building. Launching tools. Finishing a 5-part series.\ Some weeks, the return isn’t measured in dollars. It’s measured in direction.

Small trades. Strong conviction. Deep alignment.

That’s Proof of Work, too.

Nostr-PHP

Djuri submitted quite some pull requests in the last couple of week while he was implementing a Nostr connect / login on https://satsback.com. The backend of that platform is written in PHP so the Nostr-PHP library is used for several purposes while Djuri also developed quite some new features utilizing the following NIPs:

• NIP-04
• NIP-05
• NIP-17
• NIP-44

Thank you very much Djuri for these contributions. We now can do the basic private stuff with the library.

Nostr-PHP documentation

While new NIPs are implemented in the Nostr-PHP library, I'm trying to keep up with the documentation at https://nostr-php.dev. For now, things are still much work in progress and I've added the AI agent Goose using the Claude LLM to bootstrap new documentation pages. Currently I'm working on documentation for

• How to direct messages with NIP-04 and NIP-17
• Encrypted payloads for event content NIP-44
• Fetch profiledata of a given pubkey
• Lookup NIP-05 data of given pubkey
• Using the NIP-19 helper class

CCNS.news

I've moved CCNS to a new domain https://ccns.news and have partly implemented the new NIP-B0 for web bookmarks. When you post a bookmark there, a kind 39701 event is transmitted to some Nostr relays (take a look at this event for example). Optionally you can also publish this content as a note to the network.

As you can see at https://ccns.news/l/censorship-resistant-publishing-and-archiving, I've listed some todo's. All this stuff is done with Javascript using the NDK Typescript library (so I'm not using any PHP stuff for this with Nostr-PHP).

Also new: https://ccns.news/global now has a global feed which fetches all the web bookmark events with kind 39701 from several public Nostr relays. I had a rough idea to compare feeds generated with NDK and Nostr-PHP (for both using the same set of relays).

Building a njump clone for this Drupal website

You can now use this URL pattern to fetch Nostr events: https://nostrver.se/e/{event_id|nevent1|note1|addr1} where you can provide a plain Nostr event ID or NIP-19 encoded identifier. 

An example, this URL [nostr:nevent1qvzqqqqqqypzqmjxss3dld622uu8q25gywum9qtg4w4cv4064jmg20xsac2aam5nqqsqm2lz4ru6wlydzpulgs8m60ylp4vufwsg55whlqgua6a93vp2y4g3uu9lr) fetches the data from one or more relays. This data is then being saved as a (Drupal) node entity (in a database on the server where this website is hosted, which is located in my office fyi). With this saved node, this data is now also available at https://nostrver.se/e/0dabe2a8f9a77c8d1079f440fbd3c9f0d59c4ba08a51d7f811ceeba58b02a255/1 where the (cached) data is server from the database instead. It's just raw data for now, nothing special about it. One of my next steps is to style this in a more prettier interface and I will need to switch the theme of this website to a custom theme. A custom theme where I will be using TailwindCSS v4 and DaisyUI v5. 

The module which is providing these Nostr features is FOSS and uses the Nostr-PHP library for doing the following:

• Request the event from one or more relays
• Decode the provided NIP-19 identifier

For now this module is way for me to utilize the Nostr-PHP library with Drupal for fetching events. This can be automated so in theory I could index all the Nostr events. But this is not my ambition as it would require quite some hardware resources to accomplish this. 
I hope I can find the time to build up a new theme first for this website, so I can start styling the data for the fetched events. On this website, there is also a small piece (powered by another module) you can find at https://nostrver.se/nostrides doing things with this NIP-113 around activity events (in my case that's cycling what interests me).

What's next

I'm already working on the following stuff:

• Implement a class to setup a persistent connection to a relay for requesting events continuously
• Extend the documentation with the recent added features

Other todo stuff:

• Review NIP-13 proof-of-work PR from Djuri
• Implement a NIP-65 lookup for fetching read and write relays for a given npub issue #91
• Build a proof-of-concept with revolt/event-loop to request events asynchronous with persistent relay connections
• Add comments to https://ccns.news

Since 2019, the United States has been the country with the highest number of recorded cases, but Europe remains the most affected region.

According to a Binance report, the United States is the country that has recorded the greatest number of crypto-related kidnapping cases since 2019, despite a recent increase in incidents in France.

At the regional level, however, Europe remains the area with the highest number of crypto-related kidnappings: 59 cases over six years. During the same period, North America — which includes the United States and Canada — recorded 48 cases. Particularly notable is the data concerning the entire Asian continent, where 62 cases of crypto-related kidnappings have been documented, most of which are concentrated in Southeast Asian countries.

France emerges as a concerning hotspot for crypto kidnappings, with six recent cases, three of which have already occurred in 2025.

Source: Binance

The primary targets of these kidnappings include executives of crypto companies, professional traders, exchange employees, and entrepreneurs in the sector. Family members and close associates of victims are often targeted as well. An emerging phenomenon involves tourists suspected of possessing large amounts of cryptocurrency funds.

Kidnapping cases in 2025

The year 2025 has already seen particularly serious episodes of kidnappings linked to the digital asset world. The most notable case involved David Balland, co-founder of Ledger, and his wife, who were abducted from their residence in France earlier this January. The incident drew international attention from both the crypto industry and law enforcement agencies.

Another attempt took place in Paris, where armed men tried to kidnap the daughter and granddaughter of the CEO of the French exchange Paymium. Overseas, in New York, police arrested 37-year-old John Woeltz after discovering that an Italian tourist had been held captive and mistreated for weeks in a luxury Manhattan apartment.

Binance highlights a direct correlation between the price trend of Bitcoin and the increase in kidnappings. Since Bitcoin reached new all-time highs this year, attacks involving physical threats have also increased proportionally, the exchange suggests.

Source: Binance

In 2025 alone, at least 15 kidnapping episodes have already been documented, many involving ransom demands denominated in bitcoin.

Many strange spells are effected by the means of a dead man’s hand—chiefly to produce butter in the churn. The milk is stirred round nine times with the dead hand, the operator crying aloud all the time, “Gather! gather! gather!” While a secret form of words is used which none but the initiated know.

Another use is to facilitate robberies. If a candle is placed in a dead hand, neither wind nor water can extinguish it. And if carried into a house the inmates will sleep the sleep of the dead as long as it remains under the roof, and no power on earth can wake them while the dead hand holds the candle.

---

For a mystic charm, one of the strongest known is the hand of an unbaptized infant fresh taken from the grave in the name of the Evil One.

---

A dead hand is esteemed also a certain cure for most diseases, and many a time sick people have been brought to a house where a corpse lay that the hand of the dead might be laid on them.

--

The souls of the dead who may happen to die abroad, greatly desire to rest in Ireland. And the relations deem it their duty to bring back the body to be laid in Irish earth. But even then the dead will not rest peaceably unless laid with their forefathers and their own people, and not amongst strangers.

---

A young girl happened to die of a fever while away on a visit to some friends, and her father thought it safer not to bring her home, but to have her buried in the nearest churchyard. However, a few nights after his return home, he was awakened by a mournful wail at the window, and a voice cried, “I am alone; I am alone; I am alone!” Then the poor father knew well what it meant, and he prayed in the name of God that the spirit of his dead child might rest in peace until the morning. And when the day broke he arose and set off to the strange burial ground, and there he drew the coffin from the earth, and had it carried all the way back from Cork to Mayo; and after he had laid the dead in the old graveyard beside his people and his kindred, the spirit of his child had rest, and the mournful cry was no more heard in the night.

---

The corner of a sheet that has wrapped a corpse is a cure for headache if tied round the head.

---

The ends of candles used at wakes are of great efficacy in curing burns.

---

A piece of linen wrap taken from a corpse will cure the swelling of a limb if tied round the part affected.

---

It is believed that the spirit of the dead last buried has to watch in the churchyard until another corpse is laid there; or has to perform menial offices in the spirit world, such as carrying wood and water until the next spirit comes from earth. They are also sent on messages to earth, chiefly to announce the coming death of some relative, and at this they are glad, for then their time of peace and rest will come at last.

---

If any one stumbles at a grave it is a bad omen; but if he falls and touches the clay, he will assuredly die before the year is out.

---

Any one meeting a funeral must turn back and walk at least four steps with the mourners.

---

If the nearest relative touches the hand of a corpse it will utter a wild cry if not quite dead.

---

On Twelfth Night the dead walk, and on every tile of the house a soul is sitting, waiting for your prayers to take it out of purgatory.

---

There are many strange superstitions in the western islands of Connemara. At night the dead can be heard laughing with the fairies and spinning the flax. One girl declared that she distinctly heard her dead mother’s voice singing a mournful Irish air away down in the heart of the hill. But after a year and a day the voices cease, and the dead are gone for ever.

---

It is a custom in the West, when a corpse is carried to the grave, for the bearers to stop half way, while the nearest relatives build up a small monument of loose stones, and no hand would ever dare to touch or disturb this monument while the world lasts.

---

When the grave is dug, a cross is made of two spades, and the coffin is carried round it three times before being placed in the clay. Then the prayers for the dead are said, all the people kneeling with uncovered head.

The article below brings together some of the Q&A from our recent AMA on Reddit. Thanks so much for sending in your questions—we love chatting with you and being part of this awesome community!

Meepo Hardfork Features

What does Meepo bring to CKB, in simple terms?

Imagine upgrading from wooden blocks to LEGO bricks. That’s what the spawn syscall in Meepo does for CKB smart contracts, enabling script interoperability.

Spawn and a series of related syscalls are introduced as a major upgrade to CKB-VM, enabling interoperability, modularity, and better developer experience, by letting scripts call other scripts, like modular apps in an operating system.

Key features of the upgraded VM?

The upgraded CKB-VM Meepo version unlocks true decoupling and reuse of CKB scripts, enhancing modularity and reusability in smart contract development.

For instance, before Meepo, if developers wanted to build a new time lock in CKB, they had to bundle all necessary functionalities—like signature algorithms—directly into a single lock or type script. This often led to bloated scripts where most of the code was unrelated to the developer's original design goal (time lock). With the spawn syscall, scripts can now delegate tasks—such as signature checks—to other on-chain scripts. As new algorithms emerge, the time lock can adopt them without being redeployed—just by calling updated signature scripts, as long as a shared protocol is followed.

This separation allows developers to: - Focus solely on their core logic. - Reuse independently deployed signature verification scripts. - Upgrade cryptographic components without modifying the original script. - Embrace a more OS-like model where smart contracts can call each other to perform specialized tasks.

By enabling true decoupling and reuse, the spawn syscall makes CKB scripts significantly more composable, maintainable, and adaptable.

Besides Spawn, other improvements in Meepo include:

• Block Extension Fields: Enables reading extension fields in blocks, opening new possibilities like community voting on hardforks (as this ckb-zero-lock prototype). More use cases are expected.
• CKB-VM Optimization: Reduces cycle consumption for common compiler-generated code, making scripts faster and more efficient.

A practical example: IPC on Spawn

Here's an example building an entire Inter-Process Communication (IPC) layer on top of spawn syscalls: - GitHub Repo - Blog post: Transforming IPC in CKB On-Chain Script: Spawn and the Custom Library for Simplified Communication

What does “every wallet will become a CKB wallet because of ckb-auth” mean?

Current CKB-VM already comes with the power to build omnilock / ckb-auth, spawn just makes them easier to reuse in new scripts through decoupling and improved modularity.

Upgrade Compatibility Concerns

Will Meepo require a new address format?

No. Meepo does not introduce breaking changes like address format switching. The only required upgrade is support for a new hash type (data2). We aim to keep upgrades smooth and backwards-compatible wherever possible.

RISC-V & CKB’s Long-Term Design Philosophy

Ethereum is exploring RISC-V—CKB has been doing this for years. What’s your take?

The discussion about RISC-V in Ethereum, is partly about the ease of building zk solutions on Ethereum. And it's easy to mix two different use cases of RISC-V in zk:

1. Use RISC-V as the language to write programs running in a zk engine. In this case, we use zero knowledge algorithms to build a RISC-VM and prove programs running inside these RISC-V VMs.
2. Use RISC-V as the underlying engine to run cryptographic algorithms, we then compile the verifier / prover code of zero knowledge algorithm into RISC-V, then we run those verifiers / provers inside RISC-V. Essentially, we run the verifying / proving algorithms of zero knowledge algorithms in RISC-V, the programs running inside ZK VMs can be written in other languages suiting the zk algorithms.

When most people talk about RISC-V in zk, they mean the first point above. As a result, we see a lot of arguments debating if RISC-V fits in zk circuits. I couldn't get a direct confirmation from Vitalik, but based on what I read, when Vitalik proposes the idea of RISC-V in Ethereum, he's at least partly thinking about the second point here. The original idea is to introduce RISC-V in Ethereum, so we can just compile zk verifiers / provers into RISC-V code, so there is no need to introduce any more precompiles so as to support different zk algorithms in Ethereum. This is indeed a rare taken path, but I believe it is a right path, it is also the path CKB chose 7 years ago for the initial design of CKB-VM.

CKB believes that a precompile-free approach is the only viable path if we’re serious about building a blockchain that can last for decades—or even centuries. Cryptographic algorithms evolve quickly; new ones emerge every few years, making it unsustainable for blockchains to keep adding them as precompiles. In contrast, hardware evolves more slowly and lives longer.

By choosing RISC-V, we’ve committed to a model that can better adapt to future cryptographic developments. CKB may be on an uncommon path, but I believe it's the right one—and it's encouraging to see Ethereum now moving in a similar direction. Hopefully, more will follow.

CKB already stands out as the only blockchain VM built on RISC-V and entirely free from cryptographic precompiles. Meepo, with its spawn syscall, builds on this foundation—pushing for even greater modularity and reuse. We're also closely watching progress in the RISC-V ecosystem, with the goal of integrating hardware advances into CKB-VM, making it even more future-proof and a state-of-the-art execution environment for blockchain applications.

Will CKB run directly on RISC-V chips? What are the implications?

The "CKB on RISC-V"comes in several stages:

• For now, CKB-VM can already be compiled into RISC-V architecture and run on a RISC-V CPU (e.g. StarFive board), though optimized native implementations are still in development.
• That said, one key issue in the previous stage was that CKB-VM lacks a high-performance, assembly based VM on RISC-V architecture. Ironically, despite CKB-VM being based on RISC-V, we ended up running a Rust-based VM interpreter on RISC-V CPUs—which is far from ideal.

The root of the problem is that RISC-V CPUs come in many configurations, each supporting a different set of extensions. Porting CKB-VM to run natively on real RISC-V chips isn’t trivial—some extensions used by CKB-VM might not be available on the target hardware. With enough time and effort, a performant native implementation could be built, but it’s a non-trivial challenge that still needs significant work.

How do you see the RISC-V narrative expanding?

We are delighted to see the growing recognition of RISC-V in the blockchain space. For CKB, we firmly believe RISC-V is the best choice. Consensus is costly, so only essential data should be on-chain, with the chain serving as a universal verification layer—this is CKBʼs philosophy, and we have consistently designed and developed in this direction.

CKB Roadmap & Ecosystem Growth

Any plan to boost the usage of the CKB network in the next 6 - 24 months?

Growth starts with better developer experience. Spawn in Meepo significantly lowers the barrier to building complex apps. With better tools and documentation, more devs can experiment on CKB, leading to better apps and more users.

What would you focus on if the secondary issuance budget was huge?

If funding were abundant, we'd expand the Spark Program, support more grassroots projects, and even evolve toward a fully decentralized DAO structure—aligning with our long-term vision of a permissionless, community-owned network.

What’s next for Nervos after Meepo?

We're exploring new RISC-V extensions like CFI, which could boost script security and defend against ROP attacks. Still early-stage, but promising. Check out this: Against ROP Attacks: A Blockchain Architect’s Take on VM-Level Security.

Quando adolescente eu acreditava na coerência da teoria de "amor líquido" do polonês, sociólogo, Zygmunt Bauman, apresentada no livro "Amor Líquido: Sobre a Fragilidade dos Laços Humanos", qual no meu amadurecimento em estudos, sejam eles no meio acadêmico ou fora, percebo como uma das formas mais rasas de explicar as mudanças e transformações dos padrões de relações sócio-afetivas dos humanos. A seguir colocar-me-ei na minha juventude não tanto recente, direi então que nós, se adolescentes e conservadores, ou mesmo jovens adultos mais conservadores, costumamos levar como dogma uma óptica decadentista generalizada de todos os avanços de eras dos homens, universalizamos por nos ser comum a indistinção entre humanidade e humanidades, ou mesmo "humanity" e "humankind" ("humanidade" como espécime e "humanidade" como um universal), compreendemos toda "essas" como "essa" e indistinguimos as sociedades para com os homens, ou seja, a incapacidade de definir os seres dentro de suas respectivas singularidades e especificidades nos leva ao decadentismo generalista (a crença de que de forma geral, e universal, a "civilização universal" decai moralmente, éticamente, materialmente e espiritualmente), que aparente à nós determinadas mudanças nas relações humanas quanto ao caráter sócio-afetivo, por falta de profundidade e critérios ainda sobre questões alinhadas aos métodos e coerências, ou incoerências, lógicas, nós se jovens e conservadores somos levados ao engodo de concordar com a teoria do amor líquido de Bauman, que devo cá explicar de antemão: trata ela, a teoria, o padrão de "amor" dos tempos presentes como frágil, de prazo (curto e médio) e diferente em grau comparativamente ao amor comum das eras passadas.

Aos jovens mais progressistas opera uma compreensão dialética sobre as eras dos homens nos seu tempo presente, na qual ao tempo que o ser progride ele também regride simultaneamente, ou seja, a medida que aparecem contradições advindas de transformações materiais da realidade humana o ser supera essas contradições e progride em meio as transformações, ainda fazendo parte da lógica dessa indissociavelmente, assim constantemente progredindo e regredindo, havendo para esses dois vetores de distinção: o primeiro é o que releva questões espirituais como ao caráter do pensamento "new age", o segundo ignora essas questões por negar a existência da alma, seguem ao materialismo. Cedem em crer na teoria baumaninana como dogma, pois não encontram outros meios para explicar as transformações da sociedade na esfera sócio-afetiva sem que haja confrontamento direto com determinadas premissas assim pertinemente presentes, ou por não conciliarem com análises relativamente superiores, como a de Anthony Giddens sobre a "relação pura" em "A Transformação da Intimidade" e de François de Singly apresentada em "Sociologie du Couple".

https://i.pinimg.com/736x/6f/b4/9e/6fb49eda2c8cf6dc837a0abfc7e108e6.jpg

Há um problema quando uma teoria deixa de assim ser para vir a tornar-se mais um elemento desconexo da ciência, agora dentro da cultura pop, se assim podemos dizer, ou da cultura de massa, ou se preferirem mesmo "anticultura", esse problema é a sua deformização teórica, tornando-se essa rasa para sua palatabilidade massiva, somada a incapacidade de partes da sociedade civil em compreender as falhas daquilo que já foi massificado. Tive surpresa ao entender que muitos outros compartilham da mesma opinião, a exemplo, possuo um amigo na faculdade, marxista, que ao falarmos sobre nossos projetos de pesquisa, citou ele o projeto de um de nossos colegas, no qual esse referido um de nossos colegas faria seu projeto com base na teoria do amor líquido de Bauman, então alí demos risada disso, ora, para nós a teoria baumaniana é furada, passamos a falar sobre Bauman e o motivo pelo qual não gostávamos, lá fiquei até surpreso em saber que mais gente além de mim não gostava da teoria de Bauman, pois ao que eu via na internet era rede de enaltecimentos à figura e à sua teoria, tal como fosse uma revelação partindo de alguma divindade da Idade do Bronze. Pouco tempo depois tive em aula de teoria política uma citação de Bauman partindo do professor que ministrava a disciplina, no entanto, ao citar o nome de Bauman o mesmo fez uma feição na qual aparentava segurar risada, provavelmente ele também não levava Bauman à sério. Não devo negar que todas as vezes que vejo o sociólogo sendo citado em alguma nota no X, no Instagram ou qualquer outra rede social, tal como fosse um referencial teórico bom, sinto uma vergonha alheia pois alí tenho uma impressão de que a pessoa não leu Bauman e usa o referencial teórico como um fato já assim provado e comprovado.

Há pontos positivos na teoria baumaniana, como a capacidade de perceber o problema e correlacioná-lo à modernidade, assim como sucitar a influência do que há de material no fenômeno, porém os erros são pertinentes: o primeiro problema é de categoria. Não há, por parte de Bauman noção alguma entre as dissociações dos amores, não há atenção sobre o amor como estrutura ou ele como um sentimento, todo ele é compreendido uniformemente como "amor", partindo do pressuposto que todas as relações, todas elas, são firmadas com base no amor. Essa crença tem uma origem: Hegel. Nos Escritos Teológicos Hegel partia da crença que o amor ligava os seres relacionalmente como uma força de superação e alienação, mas há de compreendermos que esse Friedrich Hegel é o jovem ainda pouco maduro em suas ideias e seu sistema de pensamento, mais a frente, em "Fenomenologia do Espírito e na Filosofia do Direito", Hegel compreende a institucionalidade do direito no amor e a institucionalização dessa força, assim aproxima-se da realidade a respeito da inserção do amor nas esferas práticas do humano, porém essa ideia, apesar de imperfeita, pois ao que sabemos não é o amor que consolida a relação, mas sim a Verdade (Alétheia), conforme apontado por Heidegger em "Ser e Tempo", essa ideia do amor como a fundamento das relações humanas influenciou, e até hoje influencia, qualquer análise sobre as relações humanas fora da esfera materialista, fora dessa pois, melhormente explicado em exemplo, os marxistas (em exemplo), assim como Marx, consideram como base primordial das relações as condições materiais.

Por certo, não é de todo amor a base para a solidificação, ora, erram aqueles que creem que somente essa força, assim apontada por Hegel, constituiam todos os relacionamentos formais como pilares fundamentais, pois em prática as famílias eram até a fiduciarização dessas, por mais paradoxal que seja, compreendidas melhor como instituições orgânicas de caráter legal do que conluios de afetividades. A família outrora tinha consigo aparelhos de hierarquia bem estabelicidos, quais prezavam pela ordem interna e externa, que acima dessa instituição estava somente a Igreja (outra instituição), com sua fiduciarização [da família] após o movimento tomado pelos Estados nacionais em aplicação do casamento civil mudou-se a lógica das partes que a compõe, findou-se o princípio da subsidiariedade (não intervenção de determinadas instituições nas decisões quais podem ser exercidas em resuluções de problemas nas competências de quaisquer instituições), foi-se então, contudo, também a autoridade, e nisso revela-se um outro problema não apontado na teoria de Bauman: qual o padrão do amor "sólido"? Pois, ora, sociedades tradicionais não abdicavam do relevar dos amores para tornar seus filhos em ativos nas práticas de trocas (dádivas)? É notório que esse padrão se dissocia do padrão de sentimento apontado por Bauman, encontramos esse fato em estudo nos trabalhos "Ensaio Sobre a Dádiva", do Marcel Mauss, e "As Estruturas Elementares do Parentesco", do Claude Levi-Strauss, quais expõem que nas sociedades "sólidas", tradicionais, relevava-se mais questões institucionais que as sentimentais para a formação de laços (teoria da aliança). Muitas das relações passadas não eram baseadas no amor, não significando assim que as de hoje, em oposição, sejam, mas que permanecem-se semelhantes em base, diferentemente em grau e forma.

Ora, ainda existem casamentos motivados pela política, pelo status, pelo prestígio, pelos bens, pelo poder, pela influência familiar e assim sucetivamente, tal como no passado, ocorre que essa prática tornou-se oculta, não mais explícita e aparente, devo dizer ainda que em partes, pois prepondera em nosso tempo uma epidemia de adultérios, fornicações, práticas lascivas e demais práticas libertinosas explicitamente, em contraposição às práticas ocultas em vergonhas de sociedades sem declínio moral e espiritual, o que nos leva a questionar o método comparativo em dicotomia temporal "presente x passado" aplicado por Bauman, no qual segue-se da seguinte forma:

                     Transformação
Passado = *sólido* | Presente = *líquido*

Categorias
Padrão de amor: tradicional (*sólido*)
                            moderno (*líquido*)

*Sólido* = estável, prazo (médio-grande), profundo, determinado.
*Líquido* = instável, prazo (curto-médio), raso, indeterminado.

O que penso é: Zygmunt Bauman buscou uma explicação material e laical para desviar ao fato de que há uma notória correlação entre espiritualização da sociedade, se voltada à Verdade, com a estabilidade das instituições, o que é já reduzido à moral religiosa, somente, não à mística, como por pensadores da linha de Tocqueville, ou em abordagens também mais laical (positivista) porém ainda relevantes, como Émile Durkheim em "As Formas Elementares da Vida Religiosa" e Max Weber em "A Ética Protestante e o Espírito do Capitalismo", contrapondo uma abordage mais voltada, de fato, a espiritualidade, como Christopher Dawnson, que defende essa teoria em "Religião e o Surgimento da Cultura Ocidental", e Eric Voegelin, principalmente nas obras "A Nova Ciência da Política" e "Ordem e História".

Encerrando, minha cosmovisão é a católica, o sistema de crença e religião qual sigo é do Deus que se fez homem por amor aos seus filhos, não posso negar ou mesmo omitir o fato de que, por trás de toda a minha crítica estão meus pensamentos e minhas convicções alinhadas àquilo que mais tenho amor em toda minha vida: a Verdade, e a Verdade é Deus, pois Cristo é a Verdade, o Caminho e a Vida, ninguém vai ao Pai se não por Ele, e pois bem, seria incoerência de minha parte não relevar o fato de crença como um dos motivos pelos quais eu rejeito a teoria do amor líquido de Zygmunt Bauman, pois os amores são todos eles praticados por formas, existem por diferentes formas e assim são desde sua tradicionalidade até o predomínio das distorções de declínio espiritual das eras presentes (e também antigas pré-Era Axial), estão esses preservados pelo alinhamento à verdade, assim são indistorcíveis, imutáveis, ou seja, amor é amor, não releva-se o falso amor como um, simplesmente não o é, assim o interesse, a sanha por bens, o egoísmo e a egolatria ("cupiditas", para Santo Agostinho de Hipona, em oposição ao que o santo e filósofo trata por "caritas") não são formas do amor, são autoenganos, não bons, se não são bons logo não são de Deus, ora, se Deus é amor, se ele nos ama, determino como amor (e suas formas) o que está de acordo com a Verdade. Aprofundando, a Teologia do Corpo, do Papa São João Paulo II, rejeita a "liquidez" apresentada por Bauman, pois o amor é, em suma, sacríficio, parte da entrega total de si ao próximo, e se não há logo não é amor. A Teologia do Corpo rejeita não os fundamentos de mentira no "líquido", mas também no "sólido", pois a tradicionalidade não é sinônimo de bom e pleno acordo com o amor que Deus pede de nós, não são as coerções, as violências, as imposições e demais vontades em oposição às de Deus que determinam os amores -- fatos em oposição ao ideário romanticizado. Claro, nem todas as coerções são por si inválidas do amor, ou mesmo as escolhas em trocas racionalizadas, a exemplo do autruísmo em vista da chance da família ter êxito e sucesso, ou seja, pelo bem dos próximos haver a necessidade de submissão a, em exemplo, um casamento forjado, ou algo do gênero, reconhece-se o amor no ato se feito por bem da família, porém o amor incutido, nesse caso, explicita o caráter sacrificial, no qual uma vontade e um amor genuinamente potencial em prazeres e alegrias são anulados, ou seja, mesmo nesse modelo tradicional na "solidez" há possibilidade do amor, não nas formas romanticizadas em critérios, como "estabilidade" e "durabilidade", mas no caráter do sacríficio exercido. Conforme nos ensina São Tomás de Aquino, o amor não é uma "força", tal como ensina Hegel, mas sim uma virtude teologal conforme na "Suma Teológica" (II-II Q. 26-28), não devemos reduzir o amor e os amores em análises simplórias (não simples) de falsa complexidade extraídas em métodos questionáveis e pouco competentes à real diensão de crise espiritual das eras, por esse motivo não concordo com a teoria do amor líquido de Zygmunt Bauman.

Bitcoin Well Integrates Nostr BTC Purchases via DMs

Bitcoin Well Inc. (TSXV: BTCW; OTCQB: BCNWF) has launched an integration with Nostr, allowing US customers to buy bitcoin directly through direct messages on the decentralized social protocol, according to a press release sent to Bitcoin Magazine.

Users can link their Nostr identifier (npub) to their Bitcoin Well account and purchase bitcoin by sending specific commands via direct message. The transactions draw from the user’s Cash Balance and send the purchased bitcoin to their existing Lightning Wallet for security.

Nostr is a decentralized social media protocol which is censorship resistant and runs on a network of relays, rather than centralized servers. This means that the users have full control over their message servers. It also adds a layer of protection for the customer’s privacy.

The integration simplifies the process of buying bitcoin by allowing users to make purchases directly through a social platform they already use. As a censorship-resistant protocol, Nostr ensures Bitcoin Well and its customers have full control, avoiding restrictions and potential censorship.

“This is a great achievement for our team!” said founder and CEO of Bitcoin Well Adam O’Brien. “We are deeply committed to make buying bitcoin directly to self custody better than using a custodial exchange. This is a huge step in the right direction. We are meeting bitcoiners where they are and allowing them to buy bitcoin safely.”

Users can link their npub to their Bitcoin Well account to enable bitcoin purchases via direct message. Commands like /buy $21.00 or /stack 69000 sats initiate a transaction, which is confirmed by sending /confirm. The purchase uses funds from the user’s Bitcoin Well Cash Balance, and bitcoin is delivered over the Lightning Network to a pre-registered wallet address.

This post Bitcoin Well Integrates Nostr BTC Purchases via DMs first appeared on Bitcoin Magazine and is written by Oscar Zarraga Perez.

In a world dominated by noise, distraction, and constant motion, there’s a deeper kind of liberation that many yearn for—spiritual freedom. This is not freedom measured by external factors, but by the stillness within. It’s the kind of freedom that arises when you no longer feel enslaved by ego, fear, or the pursuit of approval.

What Is Spiritual Freedom?

Spiritual freedom is the ability to live in alignment with your highest truth. It means being free from the illusions of control, unshackled from the burdens of regret, and connected to something greater than yourself—whether that’s God, the universe, or your own divine essence.

It is peace that doesn’t depend on circumstance. It is joy that isn’t based on possession. It’s knowing who you are beyond the labels, titles, and roles you play.

Signs You’re Seeking Spiritual Freedom

You feel unfulfilled despite material success

You’re questioning your deeper purpose or path

You long for peace that outlasts the highs and lows

You’re becoming more drawn to stillness, simplicity, or presence

The Path to Inner Liberation

1. Let Go of the Ego: Ego thrives on identity, comparison, and control. Spiritual freedom comes when you stop living to protect or promote a false self.

2. Live in the Now: Freedom is found in presence. Not in what happened yesterday or what might come tomorrow, but in this exact breath.

3. Seek Connection Over Control: The more we try to control life, the more trapped we feel. Surrender doesn’t mean giving up—it means trusting a higher order and flowing with it.

4. Forgive and Release: Grudges and guilt are spiritual chains. Letting go of what weighs down your spirit is one of the most liberating things you can do.

5. Return to Love: At the heart of all spiritual freedom is love—not romantic love, but divine love, unconditional love, the kind that expands you rather than limits you.

Why It Matters

In chasing external freedom, we often forget that without inner peace, nothing ever feels free. Spiritual freedom is what makes outer success meaningful. It’s what allows us to face life’s storms without being broken by them.

---

“You find peace not by rearranging the circumstances of your life, but by realizing who you are at the deepest level.” — Eckhart Tolle

True freedom is not out there. It’s already within you—waiting to be remembered.

This is a part of the Bitcoin Infinity Academy course on Knut Svanholm's book Bitcoin: Sovereignty Through Mathematics. For more information, check out our Geyser page!

The Environment

There’s no such thing as a free lunch. There’s no such thing as a zero-sum game. The 2nd law of thermodynamics tells us this. You know, the one about entropy and how everything will be really lame in a couple of trillion years. There’s no action without an equally big reaction somewhere. This is also true for Bitcoin mining. Every once in a while, some ignorant clickbait-hungry journalist writes an article about Bitcoin’s energy usage and how it’s connected to global warming or how widespread Bitcoin adoption would kill us all someday because of its “wasteful” production process. What they all fail to address is the alternative cost. As mentioned before, Bitcoin is valuable because it's scarce, and it's scarce because it's costly to produce. The same is true for gold or diamonds or anything else that is scarce and hard to come by. As discussed in earlier chapters, the mining algorithm can never be any more energy efficient because the electricity spent is directly linked to the value of the token.

Secondly, think about what most people use their Bitcoin for. Nothing. That’s right, nothing. Bitcoin incentivizes saving rather than spending. This is the exact opposite of how people use money in our current system of fiat currencies because Bitcoin is deflationary rather than inflationary relative to all other currencies. This means that every dollar, yen, or pound spent on Bitcoin would have ended up being spent on some other energy-demanding thing had it not been spent on Bitcoin. Either that or it would have lost its value due to inflation, which implies that even more dollars, yen, or euros would have been created and spent on frivolous things. Right now, credit is cheap, and the underlying economic theory of our time is based on the idea that the amount of spending going on in society is a key metric in economics. Bitcoin, on the other hand, is based on the economic theories of the Austrian school, where saving is the key metric. Yes, Bitcoin is costly to produce, but so is overproducing every product on Earth because every business needs to expand as fast as possible to pay off their loans. Human well-being has always been, and will always be, linearly connected to energy consumption. You can’t get around or bypass this fact. Energy consumption and human flourishing are inevitably linked. The thing Bitcoin does is to take away the need for unnecessary energy consumption by incentivizing us to save for future generations. It’s a mechanism that hinders our self-destructive tendencies. Not a threat to our planet's health, but a remedy.

The next time you hear about the Bitcoin network using as much energy as a small country, ask yourself: where would all that energy have ended up if it wasn’t funneled into the only invention trying to save us from ourselves there is? Into a Chinese factory producing consumer goods shipped by boat, truck and car for temporary use and probably ending up in a garbage pile the size of a small country in less than a year? How is that better for the planet? The only place from which solutions for humanity's problems can stem is human ingenuity. Such ingenuity in turn, stems from places where people with brains have a shot at getting somewhere in life. Thanks to the Internet and Bitcoin, that somewhere is everywhere. The Internet connects us, and Bitcoin frees up our time and emancipates us from our current, destructive systems. Bitcoin helps you plant a seed and watch it grow. Before you criticize Bitcoin, try to comprehend why it was invented and what inflationary, soft money does to the mechanisms of the market. Try to understand why we have a “climate problem” in the first place — why we overconsume. What underlying forces pull our psychological strings and make us borrow money for a new car? It takes a special kind of ignorance to criticize a solution without first fully comprehending the problem.

There’s one specific word that describes the current global environmentalist movement better than any other, and that word is “hubris.” Yes, the Earth has been getting warmer, very slowly, over the last fifty years. Yes, at least one of the ice caps might be melting. Yes, it’s probably because of human activity but no, you can’t save the planet through political interference in people’s lives. To get every nation on Earth to agree that it is a good idea to forcefully make people change their behavior for the sake of the climate is not only impossible but also cruel and counterproductive. Collectivists always disguise their urge to deprive their fellow man of his or her possessions and freedoms as a necessary thing to do in order to “save” humanity. This is nothing new. They’ve just decided that “climate change” is the most effective banner to rally under right now. The causes change, but the underlying philosophy stays the same. It’s very disturbing that the socialist experiment gets to repeat itself so many times in so many parts of the world.

Human progress and human flourishing have linear relationships to energy usage. If we want to find new ways of bettering ourselves, we should use more energy, not less. Truly free market competition leads to the most efficient solutions, and there are a bunch of incentives for producers of consumable goods to find cheap energy sources. Bitcoin provides the market with yet another incentive — to find locations for and invest in power plants in remote areas of the world where the cost barrier for building the plant has been too high historically due to the costly and wasteful process of transporting electricity. Hydro-electric plants in areas with a high risk of flooding, for instance. These areas are not suitable for human settlements, but they could provide us with a lot of electricity. When producers have the option to convert electricity into money directly, they’re more likely to use renewable energy sources, not less. In this sense, Bitcoin can function as a battery for energy producers.

Offshore wind farms have a very specific wind force range where they produce a usable amount of electricity. The bigger the turbine, the wider the range, but they still have an upper and a lower wind force limit. If an offshore wind farm had been connected to a Bitcoin mining rig, the surplus energy produced on windy days could have been converted into a profit for the producer instantly. The same logic applies to solar farms and geothermal plants. Energy is not a finite resource in any practical sense for the inhabitants of Mother Earth. If we could harness and store all the power of all the sunlight that hits the Earth during just one day, we could satisfy all of humanity’s energy needs for a couple of hundred years.

Bitcoin’s role in all of this is unexplored, but its potential to be a very positive environmental force is huge, and it will prove its utility during the next century. On one hand, it provides energy producers with a battery; on the other hand, it gives central bankers a run for their money and ultimately forces them to adopt a more sound monetary policy or become obsolete altogether. Bitcoin creates an incentive for sacrificing surplus energy for a small profit and a greater good rather than just letting it go to waste. The energy harnessed is converted into a completely scarce asset that is divisible and transportable to a much greater extent than any other valuable resource on Earth. It incentivizes energy producers to think long term and will reward those most patient and least wasteful among them. This recalibration of incentive structures is, of course, not only limited to energy producers or miners but to anyone who embraces this technology and understands its implications. In due time, Bitcoin’s superior monetary properties will be undeniable to even the most stubborn dinosaur. This would be an enormous net gain for humanity and the environment.

Courageous politicians dare to implement unpopular policies. They don’t need climate-striking teenagers to tell them which issues ought to be addressed first. It is ironic how celebrities who score cheap points by talking about the climate often accuse their political opponents of being “populist.” What really happens when you raise carbon taxes and try to force populations into behaviors that they don’t really like? The gilets jaunes, or yellow vests, in France are a great example. People still have to commute to work. Raising taxes solves nothing — it just distorts the market and relocates the problem. The only thing the recently adopted environmentalist policies of France resulted in was the destruction of Paris. Arguably not the best thing for the environment.

In a truly free society, a society with sound money, climate-striking children wouldn’t be a problem. They would have to learn to cooperate in order to address whatever imaginary problem they sought to solve, which would be harmless to the rest of us. Now, when backed by fear-mongering journalists, they can cause a ton of damage as our virtue-signaling political class needs to adapt to whatever imaginary issue the press has primed us with in order to secure votes. It’s not about whether there is a real climate problem or not, but rather about motives. Always ask yourself, what does this person stand to gain from holding this particular opinion? Can this issue really be solved by political means?

There’s no such thing as a free lunch. There is such a thing as representation, however, and there’s always a personal economic motive behind political decisions. They’re not here for you; you’re here for them. One of the most eye-opening experiences of my life was seeing the lobbyist quarters in Brussels. The rise of veganism, placebic gluten intolerance, and "meat-free Mondays" in school cafeterias are all products of the food industry. A soy burger is a lot cheaper to produce than a beef one. To anyone who can sell it at a higher price by appealing to people’s vanity or world-saving hubris, huge profits await. They’ve managed to monetize our collective bad climate conscience in such a cunning way that most of us have no clue we’re being played. In the 20th century, the cereal-killers of the Kellogg's company and their likes funded “research” that cemented a fear of red meats and saturated fats into the minds of the public. The effects of this propaganda can very much still be seen today as the inhabitants of America are about twice as fat today than they were before the introduction of “light” products to the market. All of these things are connected to the root of the problem: the lack of sound money. Inflation made it possible for the food industry to replace our homemade beef burger with a mass-produced cheap soy substitute while making us believe that the price of a burger hadn’t changed that much in the last fifty years. Spoiler alert - it had.

Another of the most eye-opening experiences I’ve had was during my stay in a Mayan village in the Toledo district of Belize about ten years ago. I spent a couple of days with a family of two adults and six children in a jungle village of huts and no electricity save for two diesel generators. One night, the father of the house told me a story about his friend going into politics a decade earlier and being murdered for having the wrong opinions. We slept on wooden beds without mattresses, and a couple of dogs and turkeys ran freely around the village. One day, the family’s ten-year-old was listening to some Bob Marley songs on a CD player connected to a car battery and a small solar panel on a pole in the garden. I listened for a while and then asked him about the strange sound effects in between the songs. Helicopter sounds, machine gun sounds, and other strange noises were intersecting the songs here and there. He replied by telling me, “...oh, it’s not a proper CD. I made it with Virtual DJ on my cousin’s laptop”. I was stunned. Here was this ten-year-old, in the middle of the jungle, just as skilled with a computer as any other ten-year-old I had ever met. At that moment, I realized just how leveled the playing field has been for the workforce across the globe. Here was this child, living in a hut without even electricity (but also without a mortgage to inherit), ready to compete on the same global market as any other kid in the world.

Bitcoin is the logical next step. Bitcoin doesn’t care about nationality, gender, ethnicity, age, sexual preferences, or any other imagined victimization or privilege. To Bitcoin, we’re all equal. It is a voluntary system, and it knows no biases. Bitcoin is equality of opportunity in its purest form, and it doesn’t have any opinion on the outcome whatsoever.

So firstly you should find an emulator for whatever you want to play on. There are many for desktop and mobile devices. Checkhere for a list of all the available consoles and their various emulators.

Next what game do you want to play? This is the like the homepage for a shit ton of roms.

Some of the more popular roms are there and other various list like Sony Nintendo

After narrowing down your selection you will end up on myrient i assume this is just some dope person hosting all these so if you get some use out of it, think of donating they even take corn, but other shitcoins too (but thats not the focus here)

Once you download the Rom of the game you want, you will get a compressed (zip) folder, unzip it and within it will be the rom, most systems will identify your emulator and use it open the game. If not, launch the emulator and within it should be an option to open a file, open the file in the unzipped folder.

Enjoy So you want to Mod?

So every Mod, is a mod for a specific game [ex. Pokemon Blue, Pokemon FireRed, Super Mario Bros.] so it requires you to get the Rom for that base game, the mod itself, and a tool to patch it. There is an online tool to easily patch the mod to the ROM. IMPORTANT, this will not change any naming, Id recommend having a folder with the base game roms, and a folder for the mods, and lastly a folder for the newly modded roms. Make sure to name or just save the game in modded roms folder after the patch.

Below are a few resource to find various Pokemon Rom mods(sometimes called hacks)

• r/PokemonROMhacks
• Good Compilations of Hacks and Resource/Guides

Personally, Pokemon Unbound is considered the best most polished hack. it runs on Pokemon Fire Red.

Pokemon Emerald Rouge is a cool take on the popular Rougelite genre. This runs on base game Pokemon Emerald

I’ve written about this before. The point of this league isn’t the meager $50 entry fee and the modest prize for winning it. It’s avoiding the downside of losing the steakhouse side bet wherein you foot the bill (one year I paid $520) for a bunch of greedy gluttonous douches who stuff their faces on your dime.*

It’s a 14-team, half-PPR auction, with IDPs instead of team defenses. Here are the results:

*It’s well known I’m the greediest most gluttonous douche when I win the bet, and that is often.

My strategy was to buy three elite receivers and skimp everywhere else. It was going well until I price-enforced on Chris Olave (who I hate at his second-round ADP) and got stuck for $31. I would much rather have gone the extra mile for a $47 Amon-Ra St. Brown or spent it instead on a running back.

I thought I’d be able to get RBs cheap late too, but that wasn’t the case. After bowing out on an $18 Rhamondre Stevenson, I found myself bidding up Brian Robinson (who I like) to $16. And I wanted to pair Jerome Ford ($11) with Nick Chubb ($14), but he too got out of reach late.

Everything else went fine. I spent $4 combined on Tua Tagovailoa and Danny Dimes who in this running-QB-friendly format has more value. I also got Rashid Shaheed late because I think he’s a better player in real life than Olave and felt like I needed the insurance after that mistake.

All things considered, the draft was fine — CeeDee Lamb and Ja’Marr Chase are two top-seven overall picks, Olave is a second rounder and Stefon Diggs goes late third-early fourth, and that’s in the NFFC’s 12-team format, though unlike this, it’s full PPR.

Introduction

“There is nothing more powerful than an idea whose time has come.” -Victor Hugo

Early 1950’s America. Harry S. Truman is in office. The economy is booming and the middle class are comfortable. Shiny new television sets invite the first scenes of Hollywood into people’s homes. The Weavers, Tony Bennett, Vera Lynn and Perry Como play on the radio.

But on the fringes, in dance halls and late night clubs, a cultural revolution is brewing… A new musical fusion with influences from blues, R\&B, jazz, rockabilly, country and gospel music is about to give birth to not only a new genre, but a whole new way of life that will change society and culture, forever.

Rock & Roll

It becomes a symbol of freedom, a means of expression, and a catalyst for social change. It brings into existence a new type of counter-culture, filled with individuals who are driven to rebel against norms and authority. They don’t ask for permission. They push for change.

I believe we are witnessing such a shift now. And like rock & roll, the movement I’m speaking of is also ground up, grass roots, punk rock and will not look to authority to seek permission. The catalyst for this new social change, I believe, is Bitcoin. With its innate properties, it empowers and enables the individual like never before to achieve their fullest potential, expressed through an unprecedented freedom technology. It is an idea, like a song everyone can sing in their own way, that nobody can silence.

Revolution

"You say you got a real solution / Well you know / we’d all love to see the plan" -John Lennon

The rock & roll era helped bring about meaningful societal change through art, music, and film. It created a new social narrative. Today, the Bitcoin network is providing people with a different set of tools and ideas to build a better future in a much more practical and pragmatic way. Instead of trying to reshape social consensus and cultural norms through art forms, fashion, or lifestyle, bitcoin is achieving this through open source code.

For the first time, this technology gives individuals financial sovereignty and personal control over their own destiny, with the ability to self custody their own money that no corporation, government, dictator or king can tamper with. The individual has an opportunity to finally be freed from economic tyranny. And societies have the potential to avoid endless wars funded with printed government money. John Lennon said ‘give peace a chance’. If he were still here today and understood how bitcoin could subvert the military industrial complex would he not exclaim, ‘give bitcoin a chance’?

Natural Rights, Civil Rights, Digital Rights

"The times they are a-Changin’" -Bob Dylan

The civil rights movement was tightly interwoven with the history of rock & roll. The march on Washington, August 28th 1963, marked a seminal moment in American history for the advancement of equal rights before the law. Bob Dylan, along with Joan Baez, stood with over two hundred thousand other Americans and listened to Martin Luther King’s now immortal speech. 

People with the same values peacefully gathered in numbers to make a statement powerful enough to change the conversation. This is analogous to the same freedom-minded people today gathering in cyberspace and voting not in the traditional sense, but voting with their money – peacefully exiting and transferring their economic energy into a system where they can’t be expropriated.

The question of whether individual rights are granted or have to be secured by each individual remains a contested area of philosophy to this day. To outline each in a very crude and simplistic way, natural rights (sometimes referred to as inalienable rights) are derived from the belief that every person owns their own body, therefore their own labor, time, and energy. Civil rights, on the other hand, are granted by the state and are therefore not universal. The fact that they are rights granted to humans by other humans means they always have the potential to be revoked or withdrawn.

Digital rights granted by the power of asymmetric cryptography are based in the laws of mathematics. Combined with proof of work, based in the law of thermodynamics, this makes digital rights that bitcoin provides more akin to natural rights than civil rights, as no one person or group can unilaterally revoke those rights or confiscate your property through violence. No amount of fire power, tanks, fighter jets or nuclear weapons can break a bitcoin private key or rewrite the sunken cost of proof of work embedded into bitcoin’s timechain. This idea of securing rights without asking permission is, in itself, a revolution and achievable now in an egalitarian way. This implies a potentially huge shift in power from those with a monopoly on violence, to peaceful individuals who want to be treated fairly and with dignity.

Cypher Punk-Rock

Songwriters write songs. Cypherpunks write code.

To tie things back and look at a very narrow, but potentially huge use case of bitcoin, let’s examine the current broken incentives of the music industry, particularly recorded music. It is becoming increasingly apparent that an option other than a subscription model could find demand from content consumers and producers alike.

There is now a way, with Bitcoin and Lightning Network, for a music fan to pay artists directly and for any amount – dollars, cents or even fractions of cents. This model has positive outcomes for the music producer and fan who are the main two parties engaged in the transaction. The artist keeps all of what is sent and the listener can pay what they want. The listener can pay as they listen, rather than be locked into a rolling subscription that isn’t based on usage. This concept, called ‘value for value’, is finding its way into new music platforms such as Wavlake and Fountain. I believe this model will become the de-facto way of monetizing digital content in the coming years. This could bring an economic signal back to music that has been lost and cannot be achieved by streams alone. This will hopefully create a more meritocratic music system and shake up the entrenched streaming monoliths.

Art can shine a light on a certain truth. It can also make people look at things in a completely new way. Maybe then, Satoshi was the greatest artist who ever lived. Bitcoin smashed the conventional wisdom and theories of the most basic and prevalent thing everyone takes for granted: money. Using money as a lens to view the world can lead to distortions in your perception if the lens is warped. Removing the glasses makes you reevaluate economics, politics, religion, philosophy, morality, beauty, and almost every other aspect of life. The beauty of the Sistine Chapel, the Egyptian pyramids, the Mona Lisa, Beethoven’s 5th Symphony, Bohemian Rhapsody all intrinsically imply a certain degree of proof of work. The art, you could say, speaks for itself.

The Long and Winding Road Ahead

As a musician, I have found a new hope. The value for value movement gives me that hope. If this is truly a superior model of music distribution and consumption it will win out over time on the market.

Another point to touch on would be the possibility of this technology ushering in an artistic renaissance. I can honestly say my favorite music, the songs that have moved me the most, normally comes from a place of truth, honesty and sheer talent. Maybe I’m out of touch, but I feel popular music of late is devoid of soul, meaning and the biggest mainstream artists want to conform to the man (giant corporations/governments) instead of stick it to the man! Probably because there is nowhere else to turn now that streaming and social media platforms own their speech and art. We need to investigate and embrace new ways to own our speech and art, to make art interesting again. The powers that be, need to let it be, and leave alone individuals who wish to use this technology for their own interests if they do so in a peaceful way.

I want to leave you with a Frank Zappa quote that seems more relevant than ever:

“I’d say that today, dishonesty is the rule, and honesty the exception. It could be, statistically, that more people are honest than dishonest, but the few that really control things are not honest, and that tips the balance…” 

My charitable view is that the majority of people in power aren’t corrupt, it’s rather just a case of ‘no one is better than their incentives’. But when incentives are misaligned bad outcomes will inevitably result. With bitcoin and its incorruptible incentive structure, we have a chance to peacefully opt-out of a rigged game. I urge you to not trust, but verify with your own research that bitcoin is the answer to many of society’s current problems.

I think it’s fair to say, we all need to question ourselves and authority a little more than we’re comfortable doing, to hold truth as an ideal worth striving for, and live a little more rock & roll!

@ 8d34bd24:414be32b

It seems like most Christians today have lost their reverence and awe of God. We’ve attributed God’s awesome creation by the word of His mouth to random chance and a Big Bang. We’ve attributed the many layers of sediment to millions and billions of years of time instead of God’s judgment of evil. We’ve emphasized His love and mercy to the point that we’ve forgotten about His holiness and righteous wrath. We’ve brought God down to our level and made Him either our “buddy” or made Him our magic genie servant, who is just there to answer our every want and whim.

The God of the Bible is a holy and awesome God who should be both loved and feared.

The fear of the Lord is the beginning of knowledge;\ Fools despise wisdom and instruction. (Proverbs 1:7)

The God of the Bible is the Lord of Lords and King of Kings who “… upholds all things by the word of His power. …” (Hebrews 1:3). Yes, God loves us as sons. Yes, God is merciful. Yes, through Jesus we have the blessed opportunity to approach God directly. None of that means we get to treat God like just another friend. We are to approach God with fear and trembling and worship Him in reverence and awe.

Worship the Lord with reverence And rejoice with trembling. (Psalm 2:11)

Part of the problem is that our culture just doesn’t show reverence to authority. It focuses on self and freedom. The whole thought of reverence for authority is incomprehensible for many. Look at this Psalm of worship:

The Lord reigns, let the peoples tremble;\ He is enthroned above the cherubim, let the earth shake!\ The Lord is great in Zion,\ And He is exalted above all the peoples.\ Let them praise Your great and awesome name;\ Holy is He. (Psalm 99:1-3)

This is the way we should view God and the proper attitude for approaching God.

Another issue is that we don’t study what God has done in the past. In the Old Testament, God commanded the Israelites to setup monuments of remembrance and to teach their kids all of the great things God had done for them. When they failed to do so, Israel drifted astray.

You shall teach them to your sons, talking of them when you sit in your house and when you walk along the road and when you lie down and when you rise up. (Deuteronomy 11:19)

God has given us the Bible, His word, so that we can know Him, know His character, and know His great deeds. When we fail to be in His word daily, we can forget (or not even know) the greatness of our God.

Establish Your word to Your servant,\ As that which produces reverence for You. (Psalm 119:38)

Do you love God’s word like this? Do you hunger for God’s word? Do you seek to know everything about God that you can know? When we love someone or something, we want to know everything about it.

Princes persecute me without cause,\ But my heart stands in awe of Your words.\ **I rejoice at Your word,\ As one who finds great spoil. \ (Psalm 119:161-162) {emphasis mine}

In addition to what we can learn about God in the Bible, we also need to remember what God has done in our own lives. We need to dwell on what God has done for us. We can just try to remember. Even better (I’ll admit this is a weakness for me), write down answered prayers, blessings, and other things God has done for you. My son has been writing down one blessing every day for over a year. What an example he is!

After we have thought about what God has done for us and those we care about, we should praise Him for His great works.

Shout joyfully to God, all the earth;\ Sing the glory of His name;\ Make His praise glorious.\ Say to God, “How awesome are Your works!\ Because of the greatness of Your power \ Your enemies will give feigned obedience to You.\ All the earth will worship You,\ And will sing praises to You;\ They will sing praises to Your name.” Selah.\ **Come and see the works of God,\ Who is awesome in His deeds toward the sons of men. \ (Psalm 66:1-5) {emphasis mine}

There is nothing we can do to earn salvation from God, but we should be in awe of what He has done for us leading to submission and obedience in gratitude.

Therefore, since we receive a kingdom which cannot be shaken, let us show gratitude, by which we may offer to God an acceptable service with reverence and awe; for our God is a consuming fire. (Hebrews 12:28-29) {emphasis mine}

Are you thankful for your blessings or resentful for what you don’t have? Do you worship God or take things He has provided for granted? Do you tell the world the awesome things God has done for you or do you stay silent? Do you claim to be a Christian, but live a life no different than those around you?

Then the Lord said,

“Because this people draw near with their words\ And honor Me with their lip service,\ But they remove their hearts far from Me,\ And their reverence for Me consists of tradition learned by rote, (Isaiah 29:13)

I hope this passage does not describe your relation ship with our awesome God. He deserves so much more. Instead we should be zealous to praise God and share His goodness with those around us.

Who is there to harm you if you prove zealous for what is good? But even if you should suffer for the sake of righteousness, you are blessed. And do not fear their intimidation, and do not be troubled, but sanctify Christ as Lord in your hearts, always being ready to make a defense to everyone who asks you to give an account for the hope that is in you, yet with gentleness and reverence; (1 Peter 3:13-15) {emphasis mine}

Did you know that you can even show reverence by your every day work?

By faith Noah, being warned by God about things not yet seen, in reverence prepared an ark for the salvation of his household, by which he condemned the world, and became an heir of the righteousness which is according to faith. (Hebrews 11:7) {emphasis mine}

When Noah stepped out in faith and obedience to God and built the ark as God commanded, despite the fact that the people around him probably thought he was crazy building a boat on dry ground that had never flooded, his work was a kind of reverence to God. Are there areas in your life where you can obey God in reverence to His awesomeness? Do you realize that quality work in obedience to God can be a form of worship?

Just going above and beyond in your job can be a form of worship of God if you are working extra hard to honor Him. Obedience is another form of worship and reverence.

Then Zerubbabel the son of Shealtiel, and Joshua the son of Jehozadak, the high priest, with all the remnant of the people, obeyed the voice of the Lord their God and the words of Haggai the prophet, as the Lord their God had sent him. And the people showed reverence for the Lord. (Haggai 1:12) {emphasis mine}

Too many people have put the word of men (especially scientists) above the word of God and have tried to change the clear meaning of the Bible. I used to think it strange how the Bible goes through the days of creation and ends each day with “and there was evening and there was morning, the xth day.” Since a day has an evening and a morning, that seemed redundant. Why did God speak in this manner? God knew that a day would come when many scientist would try to disprove God and would claim that these days were not 24 hour days, but long ages. When a writer is trying to convey long ages, the writer does not mention evening/morning and doesn’t count the days.1

When we no longer see God as speaking the universe and everything in it into existence, we tend to not see God as an awesome God. We don’t see His power. We don’t see His knowledge. We don’t see His goodness. We also don’t see His authority. Why do we have to obey God? Because He created us and because He upholds us. Without Him we would not exist. Our creator has the authority to command His creation. When we compromise in this area, we lose our submission, our awe, and our reverence. (For more on the subject see my series.) When we believe His great works, especially those spoken of in Genesis 1-11 and in Exodus, we can’t help but be in awe of our God.

For the word of the Lord is upright,\ And all His work is done in faithfulness.\ He loves righteousness and justice;\ The earth is full of the lovingkindness of the Lord.\ By the word of the Lord the heavens were made,\ And by the breath of His mouth all their host.\ He gathers the waters of the sea together as a heap;\ He lays up the deeps in storehouses.\ **Let all the earth fear the Lord;\ Let all the inhabitants of the world stand in awe of Him. \ (Psalm 33:4-8) {emphasis mine}

Remembering God’s great works, we can’t help but worship in awe and reverence.

By awesome deeds You answer us in righteousness, O God of our salvation,\ *You who are the trust of all the ends of the earth* and of the farthest sea;\ Who establishes the mountains by His strength,\ Being girded with might;\ Who stills the roaring of the seas,\ The roaring of their waves,\ And the tumult of the peoples.\ They who dwell in the ends of the earth stand in awe of Your signs;\ You make the dawn and the sunset shout for joy. \ (Psalm 65:5-8) {emphasis mine}

If we truly do have awe and reverence for our God, we should be emboldened to tell those around us of His great works.

I will tell of Your name to my brethren;\ In the midst of the assembly I will praise You.\ You who fear the Lord, praise Him;\ All you descendants of Jacob, glorify Him,\ And stand in awe of Him, all you descendants of Israel. \ (Psalm 22:22-23) {emphasis mine}

May God grant you the wisdom to see His awesomeness and to trust Him, serve Him, obey Him, and worship Him as He so rightly deserves. May you always have a right view of God and a hunger for His word and a personal relationship with Him. To God be the Glory!

Trust Jesus

FYI, these are a few more passages on the subject that are helpful, but didn’t fit in the flow of my post.

Great is the Lord, and highly to be praised,\ And His greatness is unsearchable.\ One generation shall praise Your works to another,\ And shall declare Your mighty acts.\ On the glorious splendor of Your majesty\ And on Your wonderful works, I will meditate.\ Men shall speak of the power of Your awesome acts,\ And I will tell of Your greatness. (Psalm 145:3-6)

The boastful shall not stand before Your eyes;\ You hate all who do iniquity.\ You destroy those who speak falsehood;\ The Lord abhors the man of bloodshed and deceit.\ But as for me, by Your abundant lovingkindness I will enter Your house,\ At Your holy temple I will bow in reverence for You. (Psalm 5:5-7) {emphasis mine}

If you do not listen, and if you do not take it to heart to give honor to My name,” says the Lord of hosts, “then I will send the curse upon you and I will curse your blessings; and indeed, I have cursed them already, because you are not taking it to heart. Behold, I am going to rebuke your offspring, and I will spread refuse on your faces, the refuse of your feasts; and you will be taken away with it. Then you will know that I have sent this commandment to you, that My covenant may continue with Levi,” says the Lord of hosts. “My covenant with him was one of life and peace, and I gave them to him as an object of reverence; so he revered Me and stood in awe of My name. (Malachi 2:2-5) {emphasis mine}

@ 6ad3e2a3:c90b7740

From the ages of 8-11, I spent my summers in Saltaire, Fire Island, a tiny town across the bay from Bayshore Long Island, accessible only by ferry. I vaguely recall the first summer our parents enrolled my younger brother Damon and me in day camp where they made us swim in the cold, jelly-fish-ridden bay water early in the morning. We quit the camp within the week and were largely left to our own devices after that.

The island didn’t have cars, so you got around by bike. That meant it was safe for kids, and late-70s/early-80s parents could check out entirely. By the time I was 10 or 11, I would wake up whenever it suited me, scarf down a bowl of cereal, grab my bike and return for dinner. No one knew where we were — though the baseball field was a good bet — and no one cared.

I remember one time we brought a two-man inflatable raft to the ocean on a choppy day and had the bright idea to ride the waves in it. We got so destroyed by one wave, Damon wound up face-down in the sand underneath the raft. He was crying, but no real harm done.

. . .

To this day, I often find myself projecting into the future. “In 12 hours, I’ll be back in Lisbon, in 48 hours, I’ll be done with my running for the week, in 72 hours, etc.” And when the time comes, and I’m done with whatever travel or unpleasant task, I’ll start all over again.

If you tell this to someone, they’ll often say, “You need to be in the present.” Yeah no shit. That’s like telling someone you’re an alcoholic and them saying, “You should stop drinking.” It’s a bad habit, I’m aware. But where did this habit come from, and why is it so entrenched?

. . .

My summers were a stark contrast to the school year where like everyone else I was up at 7:00 am, exhausted and forced to sit through class after class all day, the teachers droning on about something in which I had no interest. I remember watching the clock, as though trying to make the hands move faster with my mind. Only 20 minutes left, only 10 minutes, only five. Thank God it’s Friday.

. . .

I’ve never had a real job. I worked on the Truckee River one summer blowing up rafts, stacking them on trucks and putting people in the water. I cleaned houses one summer, I worked for free during law school for the NY Attorney General’s office, I ghost wrote car blurbs for Motor Trend and Car And Driver and then I worked for RotoWire (in fantasy sports) for 22 years before we sold it. The idea of grinding away at a law firm or some other joyless menial mental labor filled me with dread. Even tedious tasks like editing our annual NFL magazine, going over the copy word by word four or five times was torture. And I had a dream job and owned part of the company.

. . .

I partied a lot in my 20s and 30s, and it was not without consequence. I have a beautiful 12-YO daughter now, but we started too late to have more than one kid. Had I known then what I know now, I would have started a big family much earlier. I would have been more serious and made it a priority. But even though I wasn’t exactly an alcoholic, I had a strong urge to use the weekend as an escape. It was my time, and I wanted to use it to chase the pleasures that were denied to me during the slog of the work week.

. . .

For parents, school is kid storage, but for kids like me it was prison. My biggest takeaway was there are dreadful, pointless things society wants from you, and you should get those done with the least possible effort so you could do whatever you wanted later. That life is divided into appeasing the machine and having fun, and the problem to solve was how to get rich despite having a very low tolerance for appeasement. The point of getting rich was to do whatever you wanted whenever you wanted and to dispense with the dreadful, pointless things forever.

. . .

Now that I have no job, and the dreadful, pointless things are kept to a minimum, I mostly do whatever I want. But the younger version of me would be surprised to know that includes running at the track three times a week, doing pull-ups at the local park, writing and editing my own essays, learning and using to the extent I’m capable the challenging new freedom tech protocols (bitcoin and nostr.) I’ve largely stopped drinking, almost never smoke weed, fast once a week, am gluten-free, rarely eat junk food, don’t drive a fancy car. I save rather than spend most of my money.

There is nothing from which to escape and nowhere to go anymore. And yet my mind still projects into the future, perpetuating the dichotomy between obligations and leisure, indentured servitude and escapism. It’s as if I’m back in Saltaire, the whole day every day in front of me, but it’s only June, and I haven’t yet adjusted fully to the reality that school’s out, and it’s really, actually summer.

Just as soon as I post this essay, walk the dog, do my pull-ups at the park, I’ll start to relax and enjoy myself.

Sanger sequencing traces. I extracted DNA directly from my cells and determined a short genetic sequence, which is visualized by the bottom trace. In a second sample, I mutated my DNA enzymatically and used to same process to determine the sequence, shown in the top trace. Each peak and color represents a unique DNA base (A, T, C or G) in part of a gene with 13 bases shown here in total. This biogenerative process resulted in the center base changing from T to C, resulting in a slightly different, mixed peak by comparison. To further separate this work from being purely scientific, I did not record specific details about the experimental process.
