#Bitcoin wallet designers: Do not truncate trailing zeros from the BTC denomination! Always use the same precision!. As a user, I need 15 seconds to figure out whether 0.0000089 BTC is 89 sats, 890 sats, or 8900 sats. It would've taken me 10ms if it was 0.00000890 BTC.

Germany, the country I live in, decided to magically create 100 billion Euros to spend on the war. Entirely financed by new debt. They can never raise interest rates. Nobody cares. Our fiat world is in an endless spiral of infinite credit, low interest rates, war, and collapse.

Tap-to-pay with @CashuBTC ecash — for bitcoin. Fiat credit cards nailed the UX: fast, offline, works anywhere. I always wanted that for Bitcoin. Now it’s open-source. Private. Instant. Beep, done.

I'm extremely proud to announce that I successfully defended my PhD with highest honors. Looking back at years of fundamental research in academia, I'm excited about the future. I plan to focus on Bitcoin R&D, the most impactful project my skills can contribute to. - Dr. Calle.

Experts say about Bitcoin:. - Distribution is unfair but don't count exchange wallets.- Mining is centralized but don't explain pools.- Energy use is wasteful but don't explain economics of electricity.- Doesn't scale but ignore Lightning.- All speculation but ignore human rights.

Would be an amazing proof of concept. Signal would be so much more useful if you could use it with Bitcoin. It'd be ideal for ecash since Signal already provides an extremely private communication channel over which tokens could be exchanged. We don't need another Blockchain.
Someone should fork signal and replace mobile coin with ecash.

Understand this: Lightning is the only DECENTRALIZED scaling solution on the table. Those saying Lightning is dead all push for centralized scaling. The fact is, Lightning will never cease to exist. You can't turn it off. We're a bunch of Alice's and Bob's who won't stop.

Stop shitcoining. Use Bitcoin. If Bitcoin is too slow for you, use Lightning. If Lightning is too unreliable for you, use Ecash. Just stop goddamnit. Nobody cares about your ridiculous shitcoin and you're wasting your precious life.

Every single post I make about lightning is brigaded by shitcoiners. Whether it's a positive one or a critical one. Lightning is so good that they all feel threatened by it. I have no other explanation why people could hate on a protocol so much. Let's keep melting faces.

Idk if people are ready, but I believe the world is. First tests of USD Ecash. Backed by BTC. Everyone can run a mint. Everyone can make a wallet. USD can be spent anywhere BTC is accepted. Open protocols. No gatekeepers. This is only due to the permissionless nature of Bitcoin.

Every entity holding > 1000 BTC should fund at least one Core developer. If they don't, it's just very poor risk management.

Chainalysis is the biggest sin of the crypto industry. A compliance tool that works completely in the dark. Businesses are de facto forced to use it. Legal action against ordinary people. Nobody knows how, no methods, no scientific evidence. Digital quackery. Disgusting.

There are dozens of Bitcoin "layer 2" projects with millions in VC funding and huge followings on X. None of the Bitcoiners I know has even heard of them. These projects don't go to Bitcoin conferences, they go to shitcoin conferences. Layer 2 is this cycle's scam. Be safe.

The time to synch a Bitcoin node is going to drop to seconds, and the memory required for the entire UTXO set is going be compressed to kilobytes – and you will be very happy. The significance of these projects cannot be overstated. Protect the devs working on this black magic.

It boggles my mind that people will come up with all kinds of moral issues with Bitcoin but they'll happily use Visa, MasterCard, PayPal, and other hyper-capitalist mega banks all day every day without questioning their actions even a tiny bit.

I'm incredibly honored that my work will be supported by such a based foundation. You can't imagine the peace of mind an LTS grant provides to an independent dev, so that they can focus on what's important: to ship code. Thank you OpenSats 🙏.
LONG-TERM SUPPORT FOR CALLE. @callebtc is recognized for his ongoing work with Cashu, a free and open-source bitcoin powered Chaumian Ecash protocol that greatly improves user transaction privacy and efficiency.

Went to a restaurant I found on @btcmap that accepts Bitcoin and had dinner there with friends. Paid the bill for my Udon Noodle dish from my self-custodial Lightning wallet to their self-custodial Lightning wallet. The payment took 0.5 seconds to finalize. Bitcoin is alive.

Great #Bitcoin art is complex. I particularly like the nuclear power cooling towers on the skull. Symbolism for the sustainable nuclear-powered abundant future that Bitcoin will lead us to. The artist is clearly inspired by the optimistic futurism of the Bitcoin community ♻️

Someone just sold a used graphics card for 800k sats using a market hosted on nostr (shopstr). The seller was offline while the purchase was made. The payment was a Cashu ecash token sent from buyer to seller automatically via nostr DM. Modern-folklore level Cypherpunk.

To all Lightning "critics": You're cringe af. You have no alternative to Lightning, the only decentralized Layer 2 the world has ever seen. Go shill your useless shitcoin elsewhere. The only reason you have fast txs and low fees is because nobody gives af (you have no users).
🚨 LND exploit in the wild 🚨. If you are running LND older than 0.18.5 and/or LITD older than 0.14.1, upgrade immediately. Apparently, affected Lightning nodes can be completely drained by attackers.

If you're not bullish on Greenlight by @Blockstream you might want to talk to your doctor. I've built a simple program that creates a new Lightning node. The node takes around half a second to start. I will probably implement this into everything I touch, starting with @LNbits.

I think Bitcoin Core should leave OP_RETURN as is at this point. Close the PR to let the dust settle. Technically, it will be inconsequential. Socially, it sends the right signal.

Bitcoin mining converts electricity to heat and heat can never be converted back to any useful form of energy (in the absence of a temperature gradient). Bitcoin is not digital energy. Yes, I'm a physicist.

Woa! I just made the first atomic multinut payment on mainnet and it worked!. I paid a 10 sat Lightning invoice with ecash from two different Cashu mints at the same time, each making a (partial) multi-path payment of 5 sat to the destination. Oh my god.
