In 2016, this became apparent with the DAO hack. One way to fix the problem was to implement what’s known as a “hard fork,” which would essentially update the Ethereum-based software to fix the technical gaffe that caused the hack to begin with. But DAO users had to agree to this change, and there were dissenters. Though the hard fork was approved, it created two active blockchains with two different sets of rules. Ultimately, this hack–coupled with the inability to deal with it–caused the DAO to end in 2016.
