#bitcoin is the way // tweets = own thougts

[ScienceXBT @scienceXBT]

Les corrélations reprennent leur droit :
- le SP500 est corrélé au fiat
- le #bitcoin et l'or sont inversement corrélés au fiat

Le vrai flippening c'est que Bitcoin est en train de passer d'actif risqué à valeur de reserve

@BaguetteSpendl ah bon? dans mes souvenirs c'était vite fait

[ScienceXBT @scienceXBT]

@virtualc4t @TwitterFrance on se demande!

[ScienceXBT @scienceXBT]

Bon je suis au regret d'annonce que l'assistance de @TwitterFrance ne m'aide pas à récupérer mon mot de passe de compte et que je vais probablement devoir en créer un nouveau. Je serai probablement bien moins actif et irait d'avantage sur #Nostr

Cette soirée a été une horreur pour tout le monde.

On a eu un cas psychiatrique qui a gueulé 2h pour insulter tout le monde.

Le prochain space sur la préparation au NOM sera organisé et modéré par mes soins.

On va parler concret, technique et pratique.

A dimanche soir.

⚡️DailyZap: Censorship-Resistant Permissionless Lightning Exchanges On Nostr

A very interesting whitepaper dropped into the Bitcoin-Dev mailing list last week. The idea behind Civ Kit is to use Nostr and Bitcoin/Lightning together to create a "censorship-resistant and permissionless global trading" system that everyone can access. The whitepaper is very well written, with clear yet concise explanations of the various technological pieces involved, as well as the potential pitfalls of such a system and how they can be mitigated. Well worth a read, but here's a quick summary anyway.

A maker who wishes to partake in a certain trade (for example, exchange 0.1 BTC against 10,000 Kamas) creates a Lightning Offer containing all the details of the trade (amounts, expiry period, oracle, escrow, etc.) and sends it to one or many bulletin board(s) via Lightning Onion Messages. Bulletin boards are also Nostr relays and, when one receives a trade offer, it broadcasts it to all the subscribed clients. Among those clients, if one of them finds the offer interesting and wants to take it, they do so by sending a specifically-crafted HTLC to the maker's blinded endpoint, which they specified in their Offer. From then on, the taker is committed to the trade, and either the maker is still interested and the trade happens, or the maker just lets the HTLC expire and the taker gets their funds back.

Already sounds a bit too complicated? Here's an even simpler explanation. Someone wants to trade, they send the details of the trade they're looking to make to a Nostr relay, which broadcasts the trade offer to everyone listening. Among the listeners, someone interested can then directly initiate the trade. That's it. The rest of the explanation only describes which communication medium is used where and why, to ensure both privacy for the participants and resiliency for the bulletin boards.

For example, using Lightning Onion Messages to send the trade offer from the maker to the bulletin board in the form of an Offer helps protect bulletin boards from DoS attacks, as they can enable rate-limiting based on amounts deployed in direct channels, while protecting the maker's privacy at the same time. On the other hands, Nostr totally makes sense as a publication network. Finally, complex Bitcoin contracts (for example involving escrows using multisignature schemes) can be used to perform the trade itself, either on-chain or off-chain, where such contracts can even be routed across the Lightning Network.

Of course, we are at the very beginning of the specification process of this idea, but it feels really powerful. Part of this feeling I think comes from the apparent simplicity of the system, while it will require many more building blocks to make it actually resilient and censorship-resistant, such as privacy-preserving stake certificates (a bit like the ones proposed by Riard to solve channel jamming) to enable participants to assess whether a trade counterparty is "trustworthy" or not.

At this point, I really hope you're as pumped as me. This is really an exciting subject, as the number of similar projects being built right now demonstrates.

For example Francisco Calderón shared their advancement on Mostro (which we briefly covered here) last week. The core functionality is operational, and the team is working on orders cancellation, dispute logic and a reputation system. Mostro works quite like Civ Kit in the sense that a maker sends a trade offer to a relay (a Mostro instance) which broadcasts it to listeners. Big differences are that all communications (order publishing, order taking, reputation scores) happen on Nostr, and that Mostro instances serve as escrows to settle trades between users (whereas on Civ Kit the bulletin board's role stops at broadcasting the offers it receives). The team is looking for contributors, so feel free to check out their website.

Another alternative proposal is n3xb, which stands for "Naive Nostr No-KYC Exchange". As the name suggests n3xb focuses on simplicity, in a stance not to dissimilar to the one that underpinned Nostr's design itself. All communication happens on Nostr, using a special kind even for trade offers and relays to broadcast them to the public. When a taker wants to partake in the trade, they send a Nostr DM to the maker to notify them and send the finalized details of the contract, which initiates the trade if the maker accepts.

All this various proposals are very cool. Some are more complex because they try to address complicated problems such as DoS mitigation from the get go, while others focus more on simplicity. Really looking forward what builders will come with in the coming months!

@peachbitcoin Hey @peachbitcoin and @proofofsteph @capoczino I have trouble with the phone I joined with the computer, so I can't talk! Keep it up!

About régulations it seems there is no worries to have since Peach does not issue any token and order book is p2p.

@gregory_raymond @alexis_roussel @nymproject Salut @alexis_roussel ! J'adore l'idée du projet, tout ce que j'en ai vu, j'aime beaucoup ton background, ta façon de voir les choses et même vos accomplissements récents avec Nym France. Une question subsiste : pourquoi un token?
Merci d'avance si tu prend le temps d'y répondre

@XaliCrypto as-tu vérifié les sources et les connexions entrantes et sortantes pour voir s'il y a des fuites de données?

Il y a 11 mois, @_INITIO_ parlait du gas flaring et du mining green sur @GA_Crypto_, fort des échanges avec @SebGouspillou

Quand est-ce que les médias vont faire le taf?

D'ailleurs j'avais donné un coup de main pour traduire le script en ES et EN!

@ZLOK @gillesCadignan Crusoe oui, sur le site du wef, on préfère omettre.

En tous cas c'est plutôt cool, voyons voir comment les medias reprendront cette information...

>Peut-être le WEF a-t-il compris qu'investir massivement dans le mining et dominer le hashrate c'est une voie de salut? haha
