Self-amending blockchains: Can Tezos offer an alternative to forks?

One of the main characteristics of blockchains is that, in order to evolve, they must resort to implementing hard forks. This effectively takes the chain off in a new direction while adding the necessary upgrades. Forks can be controversial since they have the power to rewrite the blockchain’s previous path. So, what are self-amending blockchains and can they offer an alternative to forks? Tezos cryptocurrency thinks so, but not everyone is in agreement.

For a fork to be successful, the majority of miners in the network must be on board. Otherwise, there’s the possibility of a new blockchain forming and the old one continuing. We’ve seen this happen plenty of times, most notably after the DAO hack in 2016 when Ethereum split in two and Ethereum Classic was born.
