Personnel: Vitalik Buterin at Ethereum Foundation (Co-founder)

Verdictpartial85%
1 check · 4/9/2026

The source confirms Vitalik Buterin as a co-founder of Ethereum and mentions 2013 as the year he proposed Ethereum (white paper). However, the record lists the start date as 2013, while the source indicates the actual deployment/launch was in 2015. The source does not explicitly mention an 'Ethereum Foundation' or Buterin's formal role with it by that name in 2013. The claim is partially correct (he is indeed a co-founder), but the start date of 2013 is ambiguous—it could refer to when he conceived/proposed Ethereum, but the actual founding/deployment occurred in 2015. The source does not clearly establish 2013 as the official start date for his role at an 'Ethereum Foundation' specifically.
