Every cryptocurrency in the ranking grouped by how its chain agrees with itself — the mechanism, not the marketing. 527 chains across 8 families, $2.48T combined.
Chains whose next block is chosen by whoever first finds a valid answer to a computational puzzle — a miner's expected reward is proportional to the work they burn.
Chains whose next block is chosen by validators who stake the chain's own coin as collateral.
Chains whose blocks are agreed on by a fixed committee of validators running a Byzantine-fault-tolerant protocol — Tendermint, HotStuff, or a close relative.
Chains whose ledger is a directed acyclic graph rather than a single chain of blocks.
Chains whose next block is chosen by proving reserved disk space — a "plot" laid down in advance, then queried against a challenge.
Chains that combine two of the mechanisms above.
Chains whose consensus is reached among a defined federation of validators — an RPCA on XRPL, Federated Byzantine Agreement on Stellar, Proof of Authority variants, or a permissioned quorum.
Chains whose consensus mechanism does not fit any of the categories above — Avalanche-family gossip protocols, threshold cryptography schemes, Proof of Importance, Proof of Burn, or otherwise custom rules.
The taxonomy — what counts as which family — is the same one applied to every asset page in the ranking. Wrapped, staked and pegged claims are never counted here.
