Sobre este episodio
Payjoin delivers transaction batching driven by real economic activity rather than waiting for pool participants, while also cutting fees through direct net settlement between counterparties.Dan Gould, maintainer of Payjoin DevKit, explains how the new async protocol and oblivious HTTP relay change what is practical for mobile wallets today.The conversation covers current live deployments in Bull Bitcoin and Cake Wallet, remaining fingerprinting heuristics beyond common input ownership, the multi-party roadmap, and how developers can integrate the library with under ten thousand lines of code.Timestamps:00:00 — Payjoin DevKit01:46 — Live Payjoins in Wallets Today04:25 — No Waiting for Batch Pools06:14 — Payjoin Works on Mobile Phones08:29 — Oblivious HTTP Hides Your IP10:05 — Fingerprinting Still an Issue?14:02 — Net Settlement Saves Big Fees15:36 — Multi-Party Payjoin Roadmap17:10 — Build Payjoin in a WeekendLinks: https://x.com/brian_trollz/status/2069465912143749462 https://github.com/payjoin/payjoin.org/pull/143 https://payjoindevkit.org/ https://x.com/bitgouldStephan Livera links:Follow me on X: @stephanliveraSubscribe to the podcastSubscribe to Substack
