In 2014, Mike Hearn was dissatisfied with the fact that his BIP (BIP64) was not adopted in time, so he released a forked version of Bitcoin, BitcoinXT.
In 2016, Gavin Andresen, the successor of Satoshi Nakamoto, launched the Bitcoin fork version Bitcoin Classic under the banner of Satoshi Nakamoto's original wish.
Also in 2016, Bitcoin Unlimited was released, aiming to provide a scalability alternative to Bitcoin;
In 2017, Chinese mining tycoon Jihan Wu supported large blocks and released Bitcoin Cash, a fork of Bitcoin;
In 2018, Satoshi Nakamoto also launched the Satoshi Vision and released a new fork, Bitcoin SV (strictly speaking, it is derived from Bitcoin Cash).
These forks all occurred in the childhood of Bitcoin, when Bitcoin had just taken shape and began to face the challenges of community rifts, miner rifts, and core developer rifts. Moreover, the initiators of each fork were people with great influence in the community.
The amazing thing is that none of these have killed Bitcoin, but have only made Bitcoin’s consensus more cohesive;
In addition, regarding forks, a deeper essence is that forks only reuse the source code of Bitcoin and do not take away the spiritual core of Bitcoin: minimization of rights;
