The validator Nakamoto coefficient is the smallest number of validators whose combined stake exceeds one-third of the total — the consensus safety threshold on a Proof-of-Stake chain. Higher is better: it means more validators would have to collude to threaten finality. QRL 2.0 validators stake equal amounts, so the coefficient tracks roughly a third of the active set — far more decentralised than stake-pool-dominated chains. QRL 2.0-only.

FAQ about this chart
Common questions about this page+
What is the validator Nakamoto coefficient?
It is the minimum number of validators whose combined stake exceeds 33% of the total staked supply — the threshold at which a colluding group could threaten the chain's finality on a Proof-of-Stake network. The higher the number, the more participants it would take to mount such an attack.
Why is QRL 2.0's coefficient so high versus Ethereum's?
Because QRL 2.0 validators each stake an equal, fixed amount, so control is spread evenly and it takes roughly a third of all validators to reach 33% of stake. Ethereum's is in the single digits because a few large staking pools (Lido, exchanges) control huge shares — equal-weight validators are structurally far more decentralised by this measure.
How is it different from the wealth Nakamoto coefficient?
The wealth Nakamoto measures concentration of coin holdings across all addresses; this measures concentration of staked validator power specifically. A chain can have concentrated wealth but well-distributed validators, or vice versa — the two answer different decentralisation questions.
