Celebrate your bitcoin pizza day with PaperEcash notes harshdev098.github.io/Paper-… @fedimint @bitshala_org #bitcoin #developer

A powerful reminder from @PastorEvanLive and @gladstein at @TheBitcoinConf: The modern world runs on open-source software maintained by people most will never know. From privacy tools to Bitcoin infrastructure, freedom survives because builders keep showing up quietly, day after day. Respect to every FOSS contributor keeping the signal alive. 🙇🧡

The official BOSS Summit After-Movie 🎬 Cypherpunks, protocol devs, and the brightest fellows in the ecosystem, all locked in together for a week.

Fedi Community Chat with Vikas of 256D & Desiboard x.com/i/broadcasts/1DxleEwmp…

India runs on UPI, which is a payment network connecting over 500 million consumers and 65 million merchants. To pay, you simply scan a QR code at the counter. With the 256D Mini App on Fedi, you can now do the same with bitcoin. Scan the UPI QR code, pay from your Fedi wallet, and the merchant receives rupees. Learn how it works: fedi.xyz/blog/256d-unlock-bi…

Having great day with bitcoin devs at bitshala summit!

Integrated @fedimint in PaperEcash project being @bitshala_org fellow while implementing the session based issuance flow (Downloading & Previewing notes is pending), added draft vs built session separation. Also have added more ecash note designs github.com/Harshdev098/Paper… #bitcoin

With the @fedimint ecosystem growing there's also more variety in wallet apps and supported modules. That's why the wallet page now shows which Fedimint modules are supported by which wallets and allows for filtering!

I have been working on PaperEcash, a @fedimint based physical ecash issuance system, as a @bitshala_org fellow Month 1: UX research, core user flows (federation → template → funding → print), and initial landing app shell live. GitHub: github.com/Harshdev098/Paper… #bitcoin

You simply don't know how good PlebQR is. I've been basically living on Bitcoin for the past couple of weeks and purchasing food, drinks, clothes, tickets with the sats I earn by shitposting on Nostr. PlebQR is an unstoppable peer-to-peer Bitcoin to fiat on and off-ramp. Every Bitcoiner deserves to have this. Read on and maybe it'll inspire you to create something similar for your region too. In Thailand, like in many other places in the world, especially in Asia, the most common digital payment methods aren't credit cards, they're QR codes. All sorts of QR codes from many different fiat payment providers. Shitty ones, good ones, it doesn't matter. As long as it's a QR code, it'll work for us. Here's where PlebQR comes in. PlebQR is what I would call a Let-me-pay-for-you app. It matches you, the person who wants to pay for a drink with Bitcoin, with a random stranger on the internet who wants your Bitcoin and pay your fiat QR bill in return! The UX is straightforward: You scan the QR code at the store, pay a Lightning invoice, and wait for the payment. No sign up needed and with incredible privacy. It works best when you're not in a hurry and when there isn't a line of people waiting behind you. Those cases are surprisingly common, think restaurant bill, or at the flea market. Right now, it usually takes a minute or two for the payment to clear but it'll get faster as more people use it. The best part though isn't that it just enables Bitcoin payments for basically everything and everywhere. It's that it represents a different, more natural form of decentralized trading that can't be stopped, and that isn't about buying and selling Bitcoin, but about spending it. I wish you could try it out some time. Pure magic Internet money ✨

Kicking off 2026, we're announcing a fulfillment of a promise that we made at launch: That Fedi would be open-source as of Jan. 3 -- the 17th anniversary of the #Bitcoin Genesis Block. @obi has more: [1/2]

To the entire @fedibtc team, thank you for making community freedom tangible. Fedi isn’t just an app; it’s a philosophy. It says: you don’t need permission to coordinate, to transact, to live sovereignly. You’ve brought Bitcoin, privacy, and peer power together, the trifecta of true independence. India’s plebs see in Fedi the blueprint for how our villages, schools, and collectives can thrive without surveillance or middlemen. We’re with you, shoulder to shoulder, building the next civilisation of freedom. ⚡🌍 #BitPlebs #Bitcoin

Wrapped up some improvements to the @fedimint Web Wallet 💻 👉 Added CI pipelines to github ⚙️ 👉 Added Unit test using jest ✅ 👉 Finished Setup for E2E tests 🧪 👉 Added federation metadata caching for faster behaviour ⚡ github.com/Harshdev098/fedim… #GitHub #Bitcoin #developer

Met a philosopher on a train today who said, “Bitcoin can’t be a work of one man. It must be an organization, maybe they still hold the passkeys and can manipulate it someday.” Me: Trust me bro, if there were secret keys, our life would be a lot easier 😆😂 #Bitcoin

#EcashCoffeeDay marks the first ecash transaction on bitcoin. ☕️Four years ago, with a cup of coffee, @EricSirion proved that bitcoin could work like cash in your pocket but private. Today, this matters more than ever. [A THREAD 🧵] The full story by @obi on @BitcoinMagazine 👇 bitcoinmagazine.com/technica…

Came to know about UCAN model for decentrailized, capabilities based authorization technique. Really a cool shift from JWT tokens to cryptographic keypair usage for user controlled authorization npmjs.com/package/@ucanto/co… #Blockchain #Decentralization #Developers

India needs educated politicians. Someone please teach them about Bitcoin
