Ethereum co-founder Vitalik Buterin took part in the Mainnet 2022 conference. He noted that the transition to the Proof-of-Stake (PoS) algorithm will be useful for any cryptocurrency on Proof-of-Work (PoW). Buterin noted that the concept of Bitcoin led him to the cryptocurrency industry. He fell in love with this technology, so Ethereum was built on the PoW algorithm. However, later the developers of the second cryptocurrency realized the benefits of switching to PoS.
