According to CoinMeta, Ark Invest and Glassnode released a joint study on September 1st that analyzed the degree of decentralization of Bitcoin, Ethereum, and Solana. The study found that only three entities were able to surpass the block production thresholds of Bitcoin and Ethereum, while Solana required 19 entities to do so. The report noted that although these three companies are considered entities in the statistics, this does not mean they control Bitcoin or Ethereum. The hash rate threshold for Bitcoin is 51%, while for Ethereum it is set at 33%. The report also analyzed the performance of each network in various dimensions such as ownership, exit liquidity, verification costs, and key resilience, and concluded that Bitcoin leads Ethereum and Solana in terms of decentralization.
