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.

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.

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!

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)_/¯
