Il ne s’agissait à l’origine que d’un aide-mémoire, mais j’ai décidé d’en faire un post de blog pour qu’il puisse servir à d’autres personnes dans la même situation que moi. J’ai commencé à suivre ces dernières semaines les réunions hebdomadaires animées par John Newbery sur irc. Ces réunions ont pour but d’analyser chaque semaine un pull request (proposition de modification du code) sur Bitcoin Core, et il est demandé aux participants de compiler une version précise de Bitcoin sur Github (une branche, dans le jargon de git) pour pouvoir comparer les changements apportés dans le code et exécuter les tests. N’étant pas développeur, j’étais vraiment peu à l’aise avec ça. Je pense que je n’étais pas le seul, et John[…]

Schnorr est un nom que tous ceux qui suivent l’actualité de Bitcoin ces dernières années ont forcément entendu. Il s’agit d’un algorithme de signature plus simple et plus efficace qu’ECDSA actuellement utilisé. Pourquoi Satoshi ne l’a-t-il pas implémenté dans ce cas ? La raison en est simplement que Schnorr était protégé par un brevet jusqu’en 2008, et qu’il n’existait donc pas de standard qui aurait permis à Satoshi d’implémenter Schnorr avec autant de sécurité qu’ECDSA(1). Mais grâce au travail de Peter Wuille et d’Andrew Poelstra, un brouillon de BIP a été proposé en juillet 2018 pour implémenter Schnorr dans Bitcoin. Concrètement, que cela va-t-il changer pour le réseau et ses utilisateurs ? Et bien de façon surprenante… pas grand-chose en[…]

“We live one click away from wreckdom”, once said a wise Bitcoin patriarch. And indeed all it took was a single click to ruin my LND node, with the very real possibility of some funds being gone for good. I eventually took it back, but it was not easy, so I’ll summarize my experience here for brothers that might do the wrong click one day too.

The only battle worth fighting for today This is part 4 of the “Hodler’s Gay Science” serie Lightning and thunder require time, the light of the stars requires time, deeds require time even after they are done, before they can be seen and heard. Revolution without violence Bitcoin is the eventuality of the more radical revolution humanity ever witnessed. It is the story of how random people from all around the world might be able to silently rip off the most powerful elite we have ever seen without firing a single gunshot. It is not only creating an alternative to the existing monetary system, but a whole social and philosophical alternative that is slowly growing out of Bitcoin and its[…]

This is part 3 of the “Hodler’s Gay Science” serie Freedom at last? My conception of freedom. – The value of a thing sometimes does not lie in that which one attains by it, but in what one pays for it – what it costs us. Now that you’re finally convinced the blockchain “technological revolution” narrative is utter bullshit, you should ask yourself what kind of revolution is Bitcoin? Or maybe it is better to call it a restoration rather than a revolution. Restoration of the freedom of the individuals pushing back against the collective bodies and powers that have been encroaching on it for the past century or so. The Great War opened a parenthesis of worldwide mass murders,[…]

This is part 2 of the “Hodler’s Gay Science” serie Opening up a new territory For believe me! — the secret for harvesting from existence the greatest fruitfulness and the greatest enjoyment is: to live dangerously! Build your cities on the slopes of Vesuvius! Send your ships into uncharted seas! Live at war with your peers and yourselves! Be robbers and conquerors as long as you cannot be rulers and possessors, you seekers of knowledge! In my opinion, Bitcoin most groundbreaking yet somewhat underrated discovery is that we can actually shape data to produce an object that is virtual but still shares the properties of physical objects that make them valuable economic goods: scarcity and rivalry. Is Bitcoin really scarce?[…]

or How I Learned to Stop Worrying and Love the Bear Market This is part 1 of the “Hodler’s Gay Science” serie Faith is always coveted most and needed most urgently where will is lacking; for will, as the affect of command, is the decisive sign of sovereignty and strength. In other words, the less one knows how to command, the more urgently one covets someone who commands, who commands severely—a god, prince, class, physician, father confessor, dogma, or party conscience. With the recent crash in price, Bitcoin naysayers feel confident again and display a cocky “told you so” attitude. It would be almost intimidating if they had not already been telling the same story dozens of times over the[…]

J'ai déjà écrit à plusieurs reprises que vous devriez avoir votre propre nœud Bitcoin, et j'ai déjà donné une ébauche de justification à cet impératif dans mes précédents articles. Néanmoins la question "pourquoi devrais-je faire tourner mon propre nœud ? Qu'est-ce que j'ai à y gagner ?" revenant fréquemment parmi mes amis, j'ai pensé qu'une explication un peu plus systématique et synthétique ne serait pas inutile. Qu'est-ce qu'un nœud (full node) ? À quoi sert-il ? Un nœud est un logiciel qui permet de communiquer et d'interagir avec le réseau Bitcoin, qui est un réseau pair à pair. La fonction essentielle du réseau Bitcoin est de garantir le respect de son protocole par l'ensemble des participants, et un nœud est[…]

[ADD-ON 03/10] BTCPay just released a new easy setup installation with Lunanode, more info here. Since my last post about BTCPay, there’s a lot that have been going on, and from today I run my own server on mainnet at https://btcpay.sosthene.net/. Feel free to suscribe on it and use it for any purpose you like.

The article below is a translation of an article I wrote originally in french. Why write this now ? This article is NOT for the blocksize debate veterans that have been around for the last three years. They have already most probably heard this argument a thousand times. I hope this article could help the newcomers or those that are not here yet, but will join us in the years to come, to understand what is the small blocks stance. In fact, I don’t like much to label myself a small blockist, as I think while the debate has been centered around this very specific issue, the divergence of view is much deeper. It is a mistake to consider it[…]
