ProtoLedger Index
Cosmos

Privacy Post-Quantum Identity

Cosmos achieves genuine BFT deterministic finality through Tendermint and has the most developed on-chain governance of any evaluated chain. Its weaknesses are shared with most: no privacy, no post-quantum security. The interchain security model introduces some centralisation considerations.

Principle Breakdown

P1 — Trustlessness 6/10

Tendermint BFT provides proven Byzantine fault tolerance. No admin keys.

P2 — Decentralisation 6/10

Validator set is permissioned (top 180 validators). Moderate concentration.

P3 — Post-Quantum Security 0/10

ECDSA only. No PQC roadmap.

P4 — Privacy by Default 0/10

No transaction privacy.

P5 — Deterministic Finality 7/10

Deterministic BFT finality within ~6 seconds. Genuine strength.

P6 — Energy Proportionality 7/10

PoS — energy efficient.

P7 — Formal Verifiability 2/10

Tendermint is documented but not formally verified in TLA+ or Lean 4.

P8 — On-Chain Governance 4/10

On-chain governance via ATOM staker votes is one of the most mature implementations. Parameter changes and upgrades executed on-chain.

P9 — MEV Resistance 1/10

No structural MEV protection.

P10 — Sybil-Resistant Identity 0/10

No identity system.
