Multisig quorum failure — 2-of-3 multisig (2019)

Survives

Case description

A November 2019 forum case describes a three-person Bitcoin partnership in a 2-of-3 multisig. One partner's signing device was destroyed in a natural disaster. The replacement process required generating a new key and coordinating with both other key holders for a quorum transaction to move funds to a new address. One partner was unreachable for six weeks during the critical window.
