Abstract Payjoin lets Bitcoin senders and receivers interact to make batched transactions. This document proposes a second, backwards-compatible, asynchronous version of the Payjoin protocol ("Version 2") relative to and described in BIP 78 ("Version 1"). An untrusted third-party "directory server" replaces the requirement for a receiver to host a secure public endpoint for interactions...

For given elliptic curve points A, B, C, G, and a scalar a known only to the prover where A = a⋅G and C = a⋅B, the prover proves knowledge of a without revealing a...
