@BitcoinAr

Fotaza sacada en la guarida de @La Crypta hace algunos meses.

Hoy jueves 16/04 a las 19:00 hs Argentina vamos a hablar sobre algunos *secretos* de la blockchain (timechain?) de Bitcoin. Otro encuentro semanal de @BitcoinAr Inscripción gratuita 👉 bit.ly/3ZcNVLS Así pueden hacer todas esas preguntas sobre curiosidades... que no les pienso responder.

Navegando en X me encuetro a alguien que, en 2026, dice que Bitcoin fue creado por la CIA y se pregunta (con tono de "mirá que buena pregunta tiro"): "quién corre los servidores de Bitcoin?" A esta altura la explicación más razonable que encuentro es que se trata de gente buscando prensa. Sino me cuesta entender la ignorancia.

Spams are an attack on Bitcoin. Filters are an attack on Bitcoin. Core is an attack on Bitcoin. Knots is an attack on Bitcoin. You are an attack on Bitcoin. Bitcoin is an attack on Bitcoin. That sums it all up I think... 🤔

Cuanto estilo! De la Bitcoineta y de esos Hardcore Bitcoiners 😎😎 View quoted note →

Estoy buscando alguna web con una lista de Hardware Wallets (signer) de Bitcoin que soporten Multisig. Idealmente alguna tabla comparativa con el soporte de cada dispositivo. Busqué pero no encontré nada aún, sin embargo es algo que creo que debe existir en algún lado. Esta lista está actualizada por ejemplo? 🤔

Does anyone know an open source Android app that is a cryptography toolbox? An app where one can encrypt/decrypt with different ciphers, hash, etc?

I would like input from you all: What consequences a normal person would have due to not caring about privacy? What spcific things could happen? The more real, common, and close to everyday reality examples the better.

What is the best REST API client testing tool? Postman? Insomnia? any other? Which one would you recommend? Open source preferably.

If I understand it correctly, any user that was awarded and accepted badges (NIP-58) can remove them from his profile by just replacing the event with kind 30008. So, it's up the clients to enable that possibility. Am I right? @Cameri🐦‍🔥 @Vitor Pamplona @jb55

What privacy focused messangers do you use normally or recommend? Which one do you think will be more used? Signal? Session? Threema? Etc..

Is it me or Nostr badges (NIP-58) are not very used? not enough interest? not many good use cases?
