Ethereum network co-founder Vitalik Buterin said Bitcoin (BTC) and Bitcoin Cash (BCH) are not the same.
On Feb. 1 Buterin tweeted responding to Brad Mills’ accusation of Buterin as Bitcoin Cash promoter:
Bitcoin cash is not bitcoin. — vitalik.eth (@VitalikButerin) February 1, 2020
Several tweets suggest Buterin is not 100% against BCH, although he clearly made the distinction that BCH is not BTC, even back in 2017. Several months after a 2017 hard fork divided BTC into two coins, BTC and BCH, Buterin tweeted a seemingly positive comment toward BCH.
1. I consider BCH a legitimate contender for the bitcoin name. I consider bitcoin's *failure* to raise block sizes to keep fees reasonable to be a large (non-consensual) change to the "original plan", morally tantamount to a hard fork. 2. Theymos's censorship. — vitalik.eth (@VitalikButerin) November 14, 2017
Almost one year later, in August 2018, Buterin again responded to BCH tweet with a comment consistent with his previous thoughts:
I disagree. "Bitcoin Cash is Bitcoin" is at this point unrealistic, but the name Bitcoin Cash by itself is totally fine. There's plenty of precedent for similar things, eg. https://t.co/9ZL7VWTIkF — vitalik.eth (@VitalikButerin) August 6, 2018
According to Buterin’s comments, the Ethereum co-founder has not always been negative toward Bitcoin Cash, but he has clearly signified a difference between BTC and BCH through the years.
In his most recent note on the subject, commenting on a BCH development fund Twitter post, Buterin said:
“In case you’re wondering what side I’m on in all of this, I’m on the side of taking public goods challenges seriously and being open to adjusting ideological preconceptions while maintaining a commitment to core values of decentralization in order to meet them.”
