Count the entities. Then ask if they are separate.
A Nakamoto coefficient is one question about consensus. It is not a certificate that a network is safe, neutral or fit for a treasury.
Decentralisation is usually a brand. The Nakamoto coefficient makes it a count: how many genuinely independent entities would have to coordinate before they could control, censor, halt or materially compromise consensus. Higher is harder to capture. It is one of the few measures that can be argued about with a number.
A July 2026 snapshot, widely cited since, put Polkadot at 166, Avalanche at 25, Solana at 18, Cardano at 15, ICP at 14 and Algorand at 12. Later rankings have kept Polkadot first and Avalanche near the top, with Cardano, Aptos, ICP, TRON and Algorand also in the leading group. The snapshot is not re-measured here. The argument does not need it to be eternal.

What the number is allowed to mean
The coefficient counts the minimum set of validators, miners or control entities required to cross the relevant threshold of network power. A high number raises the cost of coercion. Censorship gets harder. A single exchange, fund or government has fewer obvious handles.
That is a commercial fact for any network that wants to carry money or securities. Institutions will not place meaningful activity on infrastructure a handful of entities can materially control. A serious coefficient is a reason to stay in the conversation. It is not the end of the conversation.

A hundred validators can still be one failure
The question is whether the entities are economically, geographically, technically and legally separate.
The number does not see ownership hidden behind several identities. It does not see delegation piled into one custodian. It does not see a single client, a single cloud, a single jurisdiction, a foundation key, a bridge, an oracle, a sequencer, or a token distribution that lets a small group govern the upgrade. A dashboard can look plural while the failure domain is singular.
Polkadot’s nominated proof-of-stake design has repeatedly produced a high coefficient, which is why it belongs at the front of this discussion. The same paragraph has to say that a high coefficient is not a warrant of safety in every other layer. Both statements are the adult version of the chart.

From a leaderboard to an underwriting file
The useful system is not a ranking. It is a live view of consensus concentration by operator and beneficial owner, of cloud, geography, client and jurisdiction, of staking delegation and custodial influence, of upgrade keys and foundation dependencies, of bridges, oracles and sequencers, and of whether transactions are actually being included. A resilience score that does not move when control moves is a poster.
Banks, insurers, asset managers and treasuries deciding where to issue or settle need that file the way they need a custodian’s SOC report. The coefficient can be the first line. It cannot be the only line.

The standard worth holding
The future argument is not which chain has the largest integer this month. It is which network can show that no small group can quietly become the gatekeeper of the value it carries. That is a higher bar than a leaderboard, and it is the bar that matters if public infrastructure is going to hold anything a regulator will recognise.
Publish the count. Then publish the correlations the count cannot see. A network that will not do the second is asking to be trusted on the first, which is exactly the habit the coefficient was invented to retire.
