A 2-of-2 arrangement offered no resilience against single key loss, unlike a 2-of-3
SurvivesCase description
A Bitcoin business that stored treasury in a 2-of-2 multisig arrangement suffered a key loss when one partner's computer was damaged. The remaining partner held their key but without both keys, no transactions could be signed. A 2-of-2 arrangement offered no resilience against single key loss, unlike a 2-of-3 setup.
