ICYMI lnd v0.20 has been released! ⚡️github.com/lightningnetwo…⚡️ this is a major release that: adds new native channel graph SQL tables, implements a number of optimizations to reduce the load of p2p gossip traffic, adds support for DNS addresses in node announcements, and fixes many bugs as usual we recommend that all users update!

Lightning is NOT just fast payments ⚡ With Lightning you can build: - APIs - Micropayment-powered apps - Pay-per-action tools - Bots - Streaming money apps - Non-custodial wallets - New routing tools Lightning = a full development playground. The bootcamp will show you how. ➡ bit.ly/capetown-bootc…

1/7: Lightning Node Operators say they spend too much time researching which nodes to open channels towards. So, in Lightning Terminal, we introduced AutoOpen, a tool to automatically open channels designed to improve betweenness-centrality and lower costs.  🧵⚡️

Few people know they can use crypto to make everyday purchases. At @PayPal, we’re committed to revolutionizing commerce globally—and one way we are doing that is by bridging the gap between digital currencies and everyday transactions. With PayPal, consumers can seamlessly use crypto to pay at millions of merchants—just like any other payment method. Whether you hold Bitcoin, Ethereum, Litecoin, Bitcoin Cash, or PayPal USD, we convert it to fiat at checkout, making transactions smooth and familiar for both buyers and businesses. For merchants, this means unlocking a new, engaged customer base without the volatility risk of directly accepting crypto. You get paid in traditional currency, while customers enjoy the flexibility of paying with digital assets. More choice, more convenience, and more ways to do business. Crypto adoption isn’t about replacing traditional finance—it’s about enhancing it. By integrating digital currencies into our trusted payment experiences, we’re making it easier for people and businesses to transact with confidence and ease. This is just the beginning. We’re continuously innovating to ensure that PayPal remains the leader in simple, secure, and accessible digital payments.

As a developer I hate timezones SO BADLY

i had so much fun at @btcplusplus in brazil this past week; it was the biggest in-person hackathon we've ever had with over 85 devs participating on 25 project submissions big thank you to our sponsors @NYDIG @HRF @_WolfNYC @Vinteum_org @btrust_builders @base58btc @satoshilabs @FulgurVentures @getAlby @zbdapp and community partners @libdesatoshi @LaWalletOk @bitcoin_design and volunteers for making this an unforgettable event!!

PSA: If you ever had channels with LNBIG in the early days (2018-2021), read this! If you think you still have sats in such channels that you couldn't recover (e.g. your node broke down, no channel backup), there now might be a way. You only require your seed. Try...

@sliv3r__ @niftynei @renepickhardt you can specify channels in the onion, yes. But due to non-strict forwarding, if 2 peers have more than one channel between each other, then there is nothing stopping them from forwarding the onion over a channel other than the one you specified.

Is there a way to specify a payment path on LN? I know you can do it specifying the nodes hops but I would like to specify the channels. Is that possible? @ElleMouton @niftynei @renepickhardt

Mind blowing stuff! 🤯🤯🤯 Now, with the latest version of @blinkbtc, you do NOT need a second app to shop with #Bitcoin at @PicknPay! @MoneyBadgerPay have integrated their QR code scanner directly into the Blink wallet! This is permissionless innovation. 👇👇👇

Yesterday Elle Mouton (@ElleMouton) and Andrew Toth (@andrew_s_toth) joined @murchandamus & @bitschmidty to discuss Newsletter #326: - Updates to the v1.75 LN gossip proposal - Draft BIP for sending silent payments w/PSBTs - Stack Exchange Q&A Catch up: bitcoinops.org/en/podcast/202…

1/ As Bitcoin continues to grow, so does the pool of talented individuals contributing to critical codebases. However, full-time employment opportunities for these individuals remain limited.

Come and hear all the latest Gossip 😉⚡️

Elle Mouton (@ElleMouton) posted to Delving Bitcoin a description of several proposed changes to the new channel announcements protocol that will support advertising simple taproot channels... #updates-to-the-version-1-75-channel-announcements-proposal" target="_blank" rel="nofollow noopener">bitcoinops.org/en/newsletters…

The MuSig2 🎶 module has been merged into libsecp256k1. This marks significant progress in the real-world deployment of MuSig2 as it'll be available to all existing projects using libsecp256k1 with the next release. Example usage: github.com/bitcoin-core/s… The module has been designed to be as safe to use as possible. We give two rules that, when followed by the implementer, prevent nonce reuse. 333 review comments since it was merged into libsecp256k1-zkp (no significant security issue was found). Thanks to reviewers @real_or_random @theStack @pwuille @josibake @siv2r @kixunil @realtbast ‼️ Docs: github.com/bitcoin-core/s…

🎉🎉🎉Finally! MuSig2 was merged into libsecp256k1, almost 5 years after the publication of the first paper draft. 🎉🎉🎉
