ARK Invest and Glassnode have put a new number on blockchain capture risk: the smallest group of block-production entities needed to cross a protocol-relevant control threshold.
Key facts
- Rated Network, an Ethereum validator analytics provider, listed Lido at 21.17%, SSV at 16.56% and Binance at 7.77% in its Sept. 6 pool view
- ARK and Glassnode reported 19, while the Solana Foundation's June 2025 health report, using April 2025 data, recorded 20
- A Clark Moody network dashboard showed 12,959 Tor nodes among 26,837 reachable nodes on Sept. 6, or 48.3%
- The Solana Foundation's dated 2025 report counted more than 100 providers, with TeraSwitch and Latitude hosting 45.70% of stake between them
Summary
02 Pool and validator counts measure coordination risk, while hosting and shared software create separate exposures. 03 Institutions must assess ownership, infrastructure and exit speed alongside consensus thresholds. Their joint scorecard, published Sept. 1, put the threshold at three entities for Bitcoin and Ethereum and 19 for Solana. Institutions considering a blockchain as settlement infrastructure must define the failure they need to survive before selecting a metric.
