New version of nos2x-fox (the Nostr firefox signer): **v1.19.0**
I added, per request, the possibility to customize how long you want to grant authorization to an action on a site.
Add-ons marketplace: https://addons.mozilla.org/en-US/firefox/addon/nos2x-fox/
Release: https://github.com/diegogurpegui/nos2x-fox/releases/tag/v1.19.0

2026-04-16 03:36:00 GMT

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 @nprofile…hy7m
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.

Programando
Fase I:
No sabés mucho, metés todo en un solo archivo, no modularizás. Todo mezclado.
Fase II:
Súper frameworks súper modernos, hiper modularizado. Una pantalla de login toca 75 archivos... de 3 lineas cada uno.
Fase III:
Harto de la sobre-complejidad y de necesitar mapa y brújula para debuggear. Organización más simple. Menos archivos = más felicidad.

# Simple Encryption Tool
A command line tool for simple symmetric encryption where you can cipher and decipher text or file using a password with AES 256.
The project has 4 open source script files: bash, Node.js, Python and PHP. All of them with the same algorithm totally interoperable.

Mi visión sobre el precio de Bitcoin.
Primero: Mirá el precio, sube! Baja! Sube!..
Luego: El precio es irrelevante, lo que importa es ...
Ahora: El precio es muy importante, es la señal económica por excelencia.
Aún así, está MUY lejos de ser lo más interesante para hablar o debatir.

2025-11-06 22:15:33 GMT

Mañana en LABITCONF vamos a hablar de privacidad, por qué importa y qué primeros pasos tomar.

Does anyone know a platform/tool for self-hosting a blog that sources the articles from long-form notes (NIP-23) from a specific pubkey?
In other words: hosting a blog using articles from nostr.
I know of two, but both are discontinued now:

No termina de darme ese listado curado y taxativo de las que soportan multisig, y cómo.

2025-04-07 01:35:01 GMT

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? 🤔

El mecanismo de "Proof of Work" se trata del costo, no de la energía.
La energía es el mejor proxy de costo que tenemos, porque no puede "falsificarse". Y PoW hace que la probabilidad y el hash sean a su vez un proxy de energia.
Lo que importa es que cueste, y cueste mucho.

New version 1.17.0 for nos2x-fox !
This time with one requested (even by myself 😅) feature: now if a site fires many permission requests at once, they will be queued up in one unique popup window where you can approve each one separately.
As always, you can find the addon in the Firefox official store, or download-install it manually by yourself. More info: https://diegogurpegui.com/nos2x-fox/

Thanks, but I'm looking for something like a multi-tool app. OpenKeychain is specific to PGP.
Something like this:
https://play.google.com/store/apps/details?id=com.nitramite.cryptography
or this:
https://play.google.com/store/apps/details?id=com.kokoschka.michael.crypto
But none of those are really open source AFAICT

2024-12-09 04:20:40 GMT

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?

Well, it wouldn't be quite "back to where we are today" because you will have the choice to be *directly* involved if you wanted to. Today we can't, it's delegated or nothing and that is what creates most of the misalignment of incentives.
But of course there will be other issues. Apathy is one of those.

Yeah, it's true that many people will use their app.
But you don't need to. You don't need to ever user their app in order to use the device. However, that will imply you won't be able to update the firmware, although I believe they are separate functionalities (firmware update and wallet app).

I believe this data would come from those who use their wallet app. So as long as one never connects to their app, one should be fine.

If a block has 2 txs, one depending on the other, they have to be properly sorted within the block. In other words, the first tx should be placed before the second one that spends from the first.
That didn't happen with this block, hence it's invalid. No issue for the network, just wasted energy by the miner.
How did it happen? I have no idea, it's weird that something so simple got mixed up. Perhaps the txs had something uncommon that made the miner's software to mix them up.
