Solana beats Bitcoin on one key metric, but a single software bug could still take down the network

Here is the latest from the digital-asset markets: 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. Their joint scorecard, published Sept. 1, put the threshold at three entities for Bitcoin and Ethereum and 19 for Solana.

The same framework placed Bitcoin first in its composite decentralization ranking. The apparent tension reflects different forms of network exposure. The coalition needed to disrupt consensus is one risk measure; ownership, infrastructure, software, auditability and exit speed describe other routes to pressure a network.

Market Dynamics

Institutions considering a blockchain as settlement infrastructure must define the failure they need to survive before selecting a metric. What the 3/3/19 result measures The report calls the measure a critical resilience threshold. It asks how many of the largest entities must coordinate to pass a concentration point governing block production or voting power.

The inputs change by network. Bitcoin weights hash rate attributed to mining pools. Ethereum and Solana weight stake, while their dashboards may classify a liquid-staking protocol, exchange, distributed validator network, underlying operator or individual validator as the relevant entity.

Protocol rules then determine what a given percentage can accomplish. Bitcoin 3 Mining-pool labels by hash rate Concentrated block-template coordination at the report's threshold Hardware ownership, pool switching and node distribution Ethereum 3 Staking entities under the report's taxonomy Stake concentration at the selected threshold Underlying operators, attack level, clients, hosting and exit queues Solana 19 Validators by delegated stake A coalition crossing the measured one-third voting-power threshold Common owners, delegation sources, software and data centers A seven-day Bitcoin mining snapshot on Sept. 88% of blocks to Foundry USA, 16.

Market Impact

91% to AntPool and 15. The three pools coordinated block templates for 59. 04% of observed production, consistent with the report's three-pool result.

Pool share remains distinct from miner ownership. Individual miners supply work to a coordinator and can redirect that hash rate. The report estimates that a miner could leave a 1% Bitcoin position in roughly 30 seconds by switching off hardware.

This mobility makes pool concentration important for short-term censorship and template selection while leaving ultimate control of the machines more dispersed.
