Does it make sense to record a history of approvals for a Nostr browser extension?

Bitcoin es una herramienta/sistema abierto. Es inevitable que lo adopten deshonestos o enemigos.
Que celebremos que tengan la libertad de hacerlo, no significa que debamos celebrar el hecho de que lo hagan, o incluso fomentarlo.

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.

So, it's up the clients to enable that possibility. Am I right?

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.

But if someone is monitoring the messages exchange, which is easy in nostr, he could see the initial exchange of aliases. Which makes it trivial to know which alias corresponds to which pubkey.
Am I missing something?

2023-09-02 01:16:10 GMT

- reply

Hey, I just heard of this app. Nice!
What is the purpose of the alias key exchange?
And is the public nature of messages relay being solved? I mean the fact that even if the message is encrypted, the fact that I'm messaging certain user is still public.

La imprenta fue un gran invento, pero lo verdaderamente importante es la tecnología detrás de ella.
La imprenta en sí tenía su lado oscuro porque redujo las barreras para difundir ideas que eran potencialmente peligrosas para la sociedad.
Sin embargo la tecnología de "Transmisión de tinta por presión" permitió innovación en diversas industrias, logrando optimizar procesos que antes eran muy costosos. Por ejemplo, grabar símbolos o dibujos sobre telas, producir tarjetas, y reproducir en masa estampas oficiales.
☝️ Así suena cuando se dice "Bitcoin no, pero la tecnología Blockchain si".
La imprenta efectivamente redujo barreras para la libre circulación de ideas y conocimiento, lo que implicó una verdadera revolución.
Su innovación principal no fue la "transmisión de tinta por presión" sino los tipos móviles, ideal para la (re)producción de texto. Así como la innovación de Bitcoin es ordenar temporalmente registros de forma descentralizada, ideal para la transferencia de valor digital.
Ambas herramientas tecnológicas tuvieron (y tienen) un gran impacto en la humanidad, descentralizando el poder de unas pocas manos y poniéndolo al servicio de todos, en pos del progreso de la civilización.
