We will start with introductions, some basic ground rules, and jump into technical discussions. We will cover aspects of the bitcoin protocol, new research developments, recent news, and software developments.

Our newest Triangle BitDevs cohost, Jesse, will talk to us about bitcoin privacy. He’ll walk us through why privacy matters, the origin of coinjoin, and a discussion of Wasabi’s new WabiSabi protocol.

Please note the new meeting location at Carimus.

Bitcoin Core

Bitcoin Core 24.0 Release Candidate Testing Guide

Bitcoin core contributor kouloumos put together a testing guide for the 24.0 release candidate. There’s a lot of cool stuff in this release, check out his twitter thread to see the highlights in 280 char chunks.

When Taproot?

When Taproot? is a cool new site promoting adoption of taproot. It examines the stages of adoption for wallets, exchanges, and other services, why taproot adoption is a good thing, and how you can help.

Lightning

Advances in Channel Jamming Research

The prolifically productive dream team Gleb Naumenko and Antoine Riard have released a series of research reports examining channel jamming. Read the lightning-dev post for a brief summary or dive into the gitbook and read the whole shebang.

Taro alpha release

Lightning Labs has released the taro daemon alpha. Despite what the name might imply the taro daemon is not a little monster that steals your root vegetables, it is a tool to issue and transfer assets on bitcoin and lightning. Check out this blog post for the English explanation or the repo if you want to get technical.

Onion Messages and Asynchronous Lightning Payments

LDK developer vallywal explains how onion messages not only unlock bolt12 offers and blinded routes, but the combination of onion messages and PTLCs enable async payments over lightning that don’t lock up network liquidity. Really tho, the awesomest part of this blog post is all the 🔥 diagrams.

Chaumian Mints

Fedimint launches on signet

Signet is one of many bitcoin test nets. A signet launch represents a big step towards a production ready codebase. Very exciting!

Cashu

Cashu is a Chaumian Ecash wallet and mint. It’s written in python and has only lightning support, no on-chain transactions. It’s like fedimint without a federation. Plus they have an awesome new icon.

Scalability

Taro Skepticism

A critical look at the scalability properties of the Taro protocol if deployed on the bitcoin blockchain

Privacy

Coinjoin over nostr

alicexbt shared a coinjoin over nostr implementation to the bitcoin-dev mailing list. Nostr is a simple new decentralized social media protocol based on cryptographic keypairs.

Spiral block explorer

Spiral is a new Bitcoin block explorer that uses fully homomorphic encryption to guarantee the privacy of your balance lookups. Not to be confused with Jack Dorsey’s bitcoin company of the same name. Who’d have thunk that the first big name collision would include none of the words “bit”, “block”, “chain”, or “coin”. ¯\_(ツ)_/¯
