Meet Murch, a full-time Bitcoin protocol developer who co-founded his own Bitcoin development company called LocalHost Research.

As part of his day job, Murch is one of six editors who oversee the Bitcoin Improvement Proposal (BIP) process. He recently championed long-overdue changes to the BIP process. 

In my interview with Murch, we discussed his journey as a Bitcoin developer and his most recent work updating the BIP process through BIP-3. 

This interview was recorded on January 16, 2026.
