Multisig quorum failure — 2-of-3 multisig (2015)

Survives

Case description

A November 2015 forum case documents a Bitcoin business where three co-founders each held one key of a 2-of-3 multisig treasury. When two of the three co-founders had a falling out and both refused to cooperate with signing, the third co-founder was unable to move any funds.
