- friend-monoid 9y agoYup. When Bitcoin forked into Bitcoin cash, everyone was free to "double spend" - once in Bitcoin and once in Bitcoin cash. Money just up and doubled itself.
- hudon 9y agoAn actual great example is in 2013 when this happened [0]. For 24 hours, Bitcoin could not reach consensus and users could double-spend. The fact that we do not know how likely Bitcoin consensus failure is—especially when so many forks and conflicting rulesets are emerging—should worry anyone thinking about decentralized consensus.
