Dan Gould: Payjoin DevKit Ships and Breaks Common Input Ownership | SLP753
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.
