According to Wu Blockchain, ARK Invest and Glassnode have jointly released a decentralized blockchain research report. The report highlights that, in terms of critical control thresholds affecting block production, both Bitcoin and Ethereum require only 3 entities to reach the critical level, while Solana requires 19. However, the structure of mining pools and staking delegation means this metric cannot be directly equated to actual control. On the infrastructure side, Bitcoin nodes have the most balanced geographic distribution, with about 63% of nodes running via Tor. Ethereum relies more heavily on cloud service providers, with around 20% of its nodes hosted by AWS. Solana’s infrastructure, on the other hand, primarily operates in data centers. https://www.(wublock123.com)/news/news-67635
