TechFlow reports, citing Cointelegraph, that following Coinbase switching about half of its validators to Nethermind, Geth—the primary Ethereum execution client—has seen its market share drop from a peak of 84% at the end of January to 66%.
Lachlan Feeney, founder and CEO of Ethereum infrastructure firm Labrys, said: "The methodology Client Diversity uses to obtain data has flaws. Geth needs to move significantly below the 66% threshold, accounting for any margin of error, before we can be confident that a supermajority failure is impossible."
Besu holds 10% of Ethereum validator share, while Erigon, backed by Coinbase, holds 2%, bringing the total share of minority clients to approximately 34%.
