black pill: bip-110 is a case study for the current state of the world
truth doesn't matter. the mob will attach to low iq influencers and don't care about scientific accuracy.
white pill: bitcoin isn't a democracy. we don't care about how many influencers you get on your side.
the mob can't do shit. you can't vote us out. you either run our software or you create something that's better (good luck with that, your hiring strategy isn't... great).
rationality and the spirit of cooperation prevail.

If you're a Bitcoiner then you might be lucky enough to receive two whole shitcoin airdrops this year. Here is what you need to know, including a few warnings and how you can stay safe.
This year, two of the most eccentric Bitcoiners who couldn't succeessfully change Bitcoin even if they sold their mother, will finally fork off and find out how it feels to be a shitcoiner with your own chain:
- Paul Sports, the BIP300 guy who hates Lightning more than I hate shitcoins, and
- Luke Dashjr, the BIP110 guy who eats cats and can't stop thinking about CSAM.
Strange characters, great to see them go their own way.
What does that mean for you? If you have say 1 BTC to your name, you will now also have 1 Paul-BTC and 1 Luke-BTC. Even if your own Bitcoin is stored on a hardware wallet, you will now also have two shitcoins that are also secured with the same keys as your real Bitcoin.
Do I have to do anything? No. This all happens automatically. You don't need to do anything, you wouldn't even notice anything has happened. After all, what do you care whether some dude has forked Bitcoin and decided to become a shitcoiner. You can chill.
What if I want to dump it? Obviously both of these shitcoins will be worthless and will go to zero so you might be tempted to sell them. Many of us never played with shitcoins so this is a real temptation. In the most likely case, there won't even be an exchange where you can sell these coins because both are going to be pretty small and pathetic, unlike previous attacks on Bitcoin that tried to fork (Bitcoin Cash, Bitcoin Gold, ...).
If you decide to move these shitcoins to an exchange (and assuming there will be wallets that help you do so), a few things are important to keep in mind:
- There will be wallets that help you move your forked shitcoins. These wallets might ask you for your hardware wallet's seed phrase and pretend to be nice but will actually steal all your BTC. NEVER AND IN NO CIRCUMSTANCE ENTER YOUR HARDWARE WALLET'S SEED PHRASE INTO A COMPUTER. Wait for reputable wallets to appear that have been audited and thread extremely carefully. Even if you're a "pro Bitcoiner" you can lose your life savings if you mess this up. I repeat: If you enter your seed phrase into a malicious wallet, you could lose all of your REAL Bitcoins, not only that fake shit.
- If you successfully moved your shitcoins off your wallet, you might be tempted to sell them on an exchange, assuming there will be one. Note that WHICHEVER SHITCOIN UTXO YOU DOXX (i.e. connect with your identity), ALSO DOXXES YOUR REAL BITCOIN. If you deposit your Luke-shitcoin to an exchange, that exchange WILL ALLSO SEE YOUR REAL BITCOIN on the real blockchain. If you send all your shitcoins to a random guy on the internet, that random guy will also see your entire real bitcoin stack. This is because the fork mirrors Bitcoin's history.
So the summary is:
- wallets will be released that appear to help you to move your shitcoins but they actually want to steal your Bitcoin. Dangerous.
- if you move your shitcoins and connect them to your identity, then you also doxx your real bitcoins. Dangerous.
- If you don't do anything, you're safe. Basically "play stupid games, win stupid prizes".
Stay safe. Reject shitcoins.

The Cashu team builds free and open-source, production-grade software that is beautiful, polished, and easy to use.
We refuse to compromise between privacy and user experience. Privacy is a human right.
Cashu is the world's largest Chaumian ecash ecosystem, built for Bitcoin and other currencies.
People have sent money with Cashu through images, sound, satellites, radio waves, and more. It's incredibly fun.
At the same time, we're pushing the frontier of digital cash research and development.
We've built and explored:
- Programmable ecash, combining Bitcoin-like spending conditions with ecash for scripting, multisig, HTLCs, and more
- Open-source, phone-to-phone tap-to-pay
- Unruggable ecash using TEE enclaves
- Zero-knowledge credential ecash with blinded amounts and stronger privacy, using WabiSabi-style anonymous credentials
- A migration from secp256k1 elliptic-curve cryptography to BLS pairing-based cryptography
- A proof-of-liabilities scheme for ecash, optimized with sparse Merkle-sum trees for the ecash nullifier set
- Multi-nut Lightning payments, aggregating a single payment across multiple Bitcoin Lightning nodes
- Zero-knowledge scripts using STARK proofs and Cairo, contributed by StarkWare, enabling programmable ecash with spending conditions hidden even from the mint
Every day, we're working to build digital cash for the next generation.
That means crafting beautifully simple apps, equipping sovereign infrastructure, and pushing the frontier of cryptography.
Always free. Always open source.
Join us.

‼️ This week, the US House of Representatives passed the KIDS Act.
If it passes the Senate, it will be the end of the open Internet. Platforms will be forced to implement age verification. You will have to upload your government ID to post on social media.
The goal is to fully track every internet user and to implement global KYC regulation for free speech.
It was never about the kids. It’s about governments having full control over what you do and say on the Internet.
Posted something bad about your government 5 years ago? Liked a post criticizing the regime? Retweeted a post against the official narrative? Watch how protecting the kids becomes fighting terrorism or hate speech pretty soon. You will be found and you will be prosecuted.
There is no free speech in this world without a free Internet. The Internet must remain open for anyone, with or without government identification. You have a human right for privacy and for free speech.
This is a coordinated attack. Age verification laws are being proposed all over the planet, everywhere at the same time.
We must fight back.

2026-06-14 10:56:18 UTC

Many of us don't care about the Bitcoin price because it's pre-programmed.
What's on my mind and way more important to me:
1 - Does the world need Bitcoin? Yes.
2 - Is there a thriving open source ecosystem? Yes (this is my personal focus).
3 - Are there companies building on Bitcoin? Yes.
4 - Is Bitcoin used for everyday payments? Yes (this has most room for improvement).
1 is deterministic.
3 happens as a side-effect.
2 & 4 are what will ultimately determine the success of this project, and it's the one thing that's most in our hands. If we fail, it's on us.

ecash is mainly a privacy upgrade for custodial wallets. being the only person using a mint defeats that benefit. you can still it as vouchers to send people money from your node though.

Ecash denominates your Bitcoin balance. If you have a node you can run a mint but using it by yourself limits its utility.
