Le BIP-110 va-t-il créer un hard fork de Bitcoin ou nous sauver du spam ?
L’échéance d’activation du BIP arrive dans ~20 jours, voici tout ce qu’il faut savoir avant que ça arrive :
BIP-110, ou « Reduced Data Temporary Softfork », est une proposition de soft fork temporaire d’environ 1 an. Son objectif est de limiter l’inscription de données arbitraires dans Bitcoin, notamment les usages liés aux Ordinals, BRC-20, Runes, inscriptions et autres NFTs et tokens.
1⃣ Ce que BIP-110 changerait concrètement :
BIP-110 limiterait pendant 1 an plusieurs vecteurs d’inscription de données dans Bitcoin : OP_RETURN à 83 octets, certains champs à 256 octets, et certaines constructions Taproot. Les nœuds qui l’appliquent rejetteraient les blocs non conformes.
2⃣ Les arguments pour BIP-110 :
3⃣ Les contre-arguments à BIP-110 :
3⃣ Les conséquences possibles
▶️ Mon avis
Les motivations derrière BIP-110 sont louables : promouvoir Bitcoin comme réseau monétaire et nous garder à l’abri des shitcoins est un combat quotidien.
Cependant, forcer cette vision dans le consensus me semble risqué, inutile et contre-productif.
Le BIP propose de gagner 1 an, alors que le débat dure déjà depuis au moins 2 ans sans qu'aucune solution ne fasse consensus. La réalité, c'est qu'on ne peut pas bloquer l'inscription de données arbitraires dans Bitcoin sans fragiliser son consensus.
Je comprends donc les motivations de Bitcoin Core, même si je ne suis pas sûr à 100 % que la levée complète de la limite OP_RETURN soit une bonne idée. BIP-110 pose une vraie question, mais je pense que l'adopter est déraisonnable.

Beaucoup reprochent au documentaire d’Hardisk le manque de témoignages pro-Bukele.
Hier soir en live, il expliquait qu’il aurait aimé avoir quelqu’un du gouvernement, qu’il a essayé via plusieurs contacts, mais que personne n’a accepté d’être interviewé.
C’est aussi ce que j’ai vécu lors de la production de mon propre projet sur le Salvador. J’ai tout de même réussi à obtenir un court témoignage d’un membre du Bitcoin Office, notamment parce que je l’avais déjà rencontré plusieurs fois.
Mais même lorsque j’interviewais des personnes favorables au gouvernement, beaucoup restaient vagues ou évitaient les réponses politiques précises, y compris quand je les invitais explicitement à mettre en avant les points positifs de la politique de Bukele.

L'État français ne vous interdira probablement jamais de détenir du Bitcoin, mais il vous en dissuadera à tout prix.
Ce ne sera pas forcément via une interdiction frontale, ce serait trop visible, trop brutal, et la majorité de la population risquerait de ne pas comprendre.
Non, ce sera plus subtil :
Ne vous y trompez pas, l’objectif n’est pas seulement de « réguler les cryptos », mais de rendre la self-custody progressivement inconfortable, moins privée, plus risquée administrativement (et physiquement).
Faire des Bitcoiners des boucs émissaires est déjà en cours, rappelez-vous ce que la BCE écrivait dans un article de mai 2025 :
« Si les tendances actuelles de croissance rapide et d’interconnexion croissante avec la finance traditionnelle se poursuivent, les crypto-actifs finiront par présenter des risques pour la stabilité financière de la zone euro. »
La BCE parle même de « contagion ».
L'État justifiera ses mesures coercitives contre Bitcoin comme étant des mesures nécessaires pour le « bien commun », probablement pour financer une guerre sociale, sanitaire, économique ou écologique.
Et une partie de la population, endormie dopée à l'argent public, applaudira.

The Iranian people 🇮🇷 have been cut off from the Internet for 3 consecutive days.
In the digital age, cutting access to the network is the ultimate weapon of a coercive State to isolate its population and block any escape route (even financial).
A friend on the ground finds himself in a situation where he has BTC, with the difficulty of finding a means of exchange to buy basic necessities. If the Internet shutdown continues, fewer and fewer Iranians may accept crypto (including stablecoins, yet the most widely used) as long as the return of Internet access remains uncertain.
This is a critical vulnerability that I was mentionning in this report on Bitcoin adoption in Iran 🔗 https://offchain.media/article/bitcoin-revolution-iran
Let us not believe we are safe in the West. This fragility concerns us too. If we do not build resilient infrastructures now (Mesh networks, Nostr, BitChat, etc), we will be just as helpless the day the switch is turned off.
Is Bitcoin (BTC) really a currency?
To answer this question, I propose a new article that revisits several arguments. The definition of money according to Aristotle. Gresham’s law. And the Lightning Network ⚡️

On Tuesday, September 17, 2024, Samouraï Wallet’s developers made their first public appearance since their arrest during a hearing before the Southern District Court of New York.
During this hearing, the evidence presented by the prosecution was divided into 3 sets:
The defense attorneys stated that it was premature to set a trial date due to the sheer volume of documents to be reviewed, estimated at around 8 terabytes according to William Hill's lawyer.
He also referenced a letter published by Senators Cynthia Lummis and Ron Wyden, asserting that non-custodial services, where users retain full control of their assets, should not be considered money transmission services, as they do not receive or control users' funds.
According to the letter, this interpretation contradicts FinCEN's (Financial Crimes Enforcement Network) guidelines, which exclude non-custodial services from regulatory obligations concerning money transmission.
Relying on this letter, the defense attempted to file a motion to dismiss the charges, but it was rejected by the judge.
Moreover, the judge also refused to modify the defendants' bail conditions, citing the risk of flight. A new hearing was scheduled for December 17, 2024.

Heard about Senator Lummis's "#Bitcoin Act of 2024"? The one proposing US 🇺🇸 governement to create a strategic reserve of 1,000,000 BTC?
Here is what you have to know about it 👇
On the same day as Trump's speech at
, Cynthia Lummis introduced a strategic Bitcoin reserve legislation.
The goal is simple 🎯 buying 1 million BTC to pay down the national debt, wich is over 35 trillion dollars 💸
Senator Lummis officially published the bill, here are some highlights 👇
FINDINGS
The bill starts by highlighting Bitcoin's utility, resilience, role as a medium of exchange 💱 and its potential to benefit the US economy 🇺🇸
It says that, like gold 🪙, Bitcoin is seen as an asset that can strengthen the US financial position 📈
ESTABLISHMENT OF STRATEGIC BITCOIN RESERVE
The bill proposes to create a decentralized network of BTC storage 🔐 among various states of the country to ensure the long-term custody and management of private keys 🗝️ held by the government
BITCOIN PURCHASE PROGRAM
The proposed law 🧑⚖️ requires The Secretary of the Treasury to:
1⃣ Buy at least 200,000 Bitcoins per year for 5 years, totaling 1 million BTC; 2⃣ Make these purchases transparently with a strategy to minimize the impact on Bitcoin's price; 3⃣ Hold these Bitcoins for at least 20 years to ensure long-term stability and security; 4⃣ Not sell, exchange, auction, or otherwise dispose of the funds for any purpose other than repaying federal debt; 5⃣ Never sell more than 10% of the reserves over a 2-year period.
PROOF OF RESERVE SYSTEM
Additionnally, the Secretary of the Treasury must :
OFFSETTING THE COST OF THE STRATEGIC 5 BITCOIN RESERVE
Lummis' law requires that between 2025 and 2029, the first $6 billion of net profits remitted by FED banks 🏦 to the Treasury will be used to fund the Bitcoin purchase program.
PROTECTION OF PRIVATE PROPERTY RIGHTS
The legislation concludes by defending private proprety rights 🕊️
"Nothing in this Act shall be construed to authorize the Federal Government to seize, confiscate, or otherwise impair any property right in the lawfully acquired Bitcoin holdings of any person; or infringe upon the rights of individuals, businesses, or organizations to purchase, hold, transfer, or dispose of Bitcoin in accordance with the law"
And what I feel is the most important 👇
“AFFIRMATION OF RIGHTS. This Act affirms and protects the rights of persons to maintain full lawful control over the Bitcoin and other digital assets of those indi-viduals, recognizing that the ability to maintain self-cus-tody of private keys is fundamental to the principles of financial sovereignty, privacy, and personal liberty in the digital age.”

🥕Taproot Assets allowing stablecoins is nice... But is it the best solution to exchange dollars💵 over Bitcoin and Lightning⚡️Network?
❗️Spoiler: No
Stablecoins like USDT over Bitcoin is only a bit better of USDT over Ethereum or Solana.
Even though Bitcoin is more censorship resistant than all its (pale) copies, Tether and Circle are the custodians of the dollar you think you own, and if they choose, or if they are forced too, they will freeze your funds.
Moreover, Lightning Service Providers (LSPs) could become regulatory and technological choke points.
If LSPs are influenced or strictly regulated, they might compromise ⚡️LN's decentralization and users sovereignty by enforcing compliance👩⚖️ KYC 🪪 and regulated stablecoin issuers over the ⚡️Lightning Network could even, by choice or regulation, prohibit their assets from transiting through unknown nodes 🪢
So, what is the solution to avoid censorship? 👉 1 answer, 3 letters : DLCs
Discreet Logs Contracts (DLC) enable P2P 🤝derivative positions over #Bitcoin and Lightning⚡️
They allow users to open/close positions, like shorts 📉, on BTC vs. USD. This stabilizes portfolio value by offsetting BTC volatility.
How to use them? 👉1 answer, 5 bits : 10101
10101 creates USDP, a BTC derivates that keeps the value of USD. (https://10101.finance/)
USDP, once fully launched, will be more sovereign 👑 more secure 🔒 more censorship resistant 🏦 than any stable asset ever create 💵 (yes more than US banknotes).

TRUMP 🗣️: "There in El Salvador 🇸🇻 murders are down by 70% ! Why are they down? Now he would have you convinced that's because he has trained murders to be wonderful people now. They are down because they are sending their murders to the United States"
Here is why he's wrong 👇
1⃣ Homicide rate in El Salvador 🇸🇻 was 2.4 per 100k inhabitants in 2023, down 93% since 2019 and 98% since 2015.
2⃣ In the United States 🇺🇸 it was 5 per 100k inhabitants in 2023, down 50% since 1980.
On top of providing wrong metrics (claiming there are more murderes in the US than before and that murders are down 70% in 🇸🇻), here Trump is clearly manipulating truth to serve his own agenda and prepare justifications for future regulations.
PS: I am not pro Biden either
