There is a particular brand of argument about the Ethereum/Ethereum Classic fork in the Bitcoin community that is both universally prevalent and demonstrably incorrect. This is an argument that I’ve seen made by Bitcoin developers, miners, and vocal users ad nauseum. The argument plays into fears in Bitcoin fork politics, and roughly proceeds as follows: The ETH/ETC fork event was a negative action that harmed the Ethereum community and its token’s underlying value.
A useful introduction to such anti-fork arguments in the context of Bitcoin can be seen in this slide.
In this brief article, I propose both a logical and an empirical argument that claiming these tenets apply to Ethereum is dead wrong. Not only was forking the optimal action for the Ethereum community at the time, but it did not harm the community in any meaningful way (and may have benefited it in others!)
This article is targeted at explaining why the Ethereum fork was undeniably beneficial to Bitcoin users who may be unfamiliar with Ethereum; to Ethereum users, I’m likely preaching to the choir and will be contributing nothing new of substance.
