State of the transaction privacy work in Bitcoin

A recent podcast episode with Dan Gould on the state of Payjoin.

The website has a transcript and a link to the video, my notes below:

  • Payjoin Foundation is a non-profit dedicated to supporting Payjoin
  • Payjoin Dev Kit 1.0.0 release imminent (payjoin-1.0.0-rc.4 in releases)
  • BIP-77 (AKA Payjoin v2 / async Payjoin)
  • Async Payjoin is available in Cake Wallet and Bull Bitcoin Mobile
  • Current focus: getting PDK 1.0.0 released, getting BIP-77 out of draft
  • Future work: addressing privacy problems, multi-party Payjoin
  • Blog post: How Wallet Fingerprints Damage Payjoin Privacy.
