Ethereum co-founder Vitalik Buterin questioned the decentralization level of those cryptocurrencies that promise a high transaction throughput and stood up for the Proof-of-Work algorithm.

Speaking at the Blockchain Connect conference in San Francisco, Vitalik Buterin answered the question about whether the Ethereum team was developing a solution for a significant increase in network bandwidth. According to him, the very formulation of the problem is fundamentally wrong.

“So I’ve noticed a lot of misconceptions here. Because, like, there’s a lot of like, honestly, bad crypto projects that try to claim. Oh, because we use fancy BFT, we can do 5,000 transactions per second and proof-of-work can only do 15.”

Speaking about various algorithms of consensus and why they became one of the most discussed issues, Buterin noted that he sees many misconceptions regarding the true goal of the consensus algorithm. In his opinion, the main goal of consensus protocols is not to make its blockchain faster, but how to make it more secure.

“When a blockchain project claims ‘We can do 3,500 TPS because we have a different algorithm,’ what we really mean is ‘We are a centralized pile of trash because we only have 7 nodes running the entire thing.”

Speaking about an unnamed “pile of trash” project with 7 nodes, Buterin seems to be referring to NEO, which currently has only 7 active consensus nodes.
