Our first Bitcoin meetup in Kolkata is here! 🎉

Bitcoin 101: How Digital Money Works Without Banks

📅 Saturday, 22 August
🕦 11:30 AM–1:30 PM

Every economy depends on a ledger to keep track of who owns what. Bitcoin is the first global financial ledger maintained by mathematics, cryptography, and a distributed network—not by banks.

Join us for an interactive, beginner-friendly introduction to Bitcoin and how it works. No prior knowledge is required—just bring your curiosity!

[Citadel FOSS @citadelfoss]

Thank you @bitcoinoptech for covering us. It was a pleasure sharing our progress and getting Coinswap in front of the devs.

If you listen to it, please give Coinswap a spin. You can either try our example apps, or build your own using our FFIs.

the government of india does not like technologies like bitchat and wants it taken down

[calle @callebtc]

UPDATE: Bitchat is now mirrored on @Radicle — censorship-resistant, peer-to-peer code hosting:

iOS/macOS: rad:z2v9tRJz1oknFAqCSY5W5c76nVvm6
Android: rad:z347HbE1F4c77DVLvsPe2ApoEEw6f

Clone it. Seed it. Keep it alive. 👇

@citadelfoss @bitgould coinswap + payjoin may break both common input heuristic and data leakage to the payjoin partner, once the other output may be instantly swapped

[floppy.md @1440000bytes]

@computeiroAncap @citadelfoss 💯

[Computeiro Ancap @computeiroAncap]

@citadelfoss @sethforprivacy coinswap may be an option inside the cake wallet swaps menu, in the option BTC -> BTC, unless I am mistaken, today not available

[Computeiro Ancap @computeiroAncap]

@citadelfoss @1440000bytes I think coinswap may interact pretty well with octojoin

[Citadel FOSS @citadelfoss]

@nvk https://t.co/Rl0KYXBpJ0

[Citadel FOSS @citadelfoss]

It does!! Please help bring it in attention to wallet devs.

We have made it absolutely easy for any wallet to integrate via language bindings.

[Computeiro Ancap @computeiroAncap]

@citadelfoss I think this protocol deserves a marketing campaing with wallet devs, just as payjoin

Bitshala Vadodara Meetup #6 ⚡
🗓 Friday, 24th July, 5:00 pm

Topic: Inside a Bitcoin Transaction - What Really Happens After You Hit "Send"?

Every transaction follows a fascinating journey before it becomes part of the blockchain.

Most people use Bitcoin but only a few understand what actually happens under the hood.

Join us as we trace a transaction from the moment you hit Send to its final confirmation, exploring the mempool, validation, mining, and more.

Bring your laptop. Walk away with a practical understanding of how Bitcoin really works, meet fellow Bitcoin builders, and connect with the local developer community.

One of the most underrated project bewing out there.

[Citadel FOSS @citadelfoss]

We have built this over last 3 years.

Maybe now with the new X fix cypherpunks can actually know about it.

Please share to spread the word. 🙏
