Ouroboros (Proof-of-Stake)

Cardano

Privacy Post-Quantum MEV

Cardano is the most formally-specified of the major chains — its Ouroboros consensus protocol has been peer-reviewed and partially verified. It scores well on trustlessness, finality, and energy, but has no privacy, no post-quantum security, and its on-chain governance (Voltaire) is still maturing.

Principle Breakdown

P1 — Trustlessness 7/10

Ouroboros is a formally proven PoS protocol. Trustlessness is well-established.

P2 — Decentralisation 5/10

Stake pool distribution is better than most chains. Nakamoto Coefficient approximately 10-15.

P3 — Post-Quantum Security 0/10

ECDSA only. No PQC roadmap published.

P4 — Privacy by Default 0/10

No transaction privacy.

P5 — Deterministic Finality 7/10

Ouroboros Praos provides probabilistic finality with deep settlement. Ouroboros Genesis improves this. Not fully deterministic BFT.

P6 — Energy Proportionality 7/10

PoS — energy efficient. Strong score.

P7 — Formal Verifiability 3/10

Ouroboros protocols are peer-reviewed academic papers, partially verified. Best formal specification record of any major chain.

P8 — On-Chain Governance 2/10

Voltaire era introduces on-chain governance via Project Catalyst and Constitutional Committee. Still developing but directionally correct.

P9 — MEV Resistance 1/10

No structural MEV protection.

P10 — Sybil-Resistant Identity 0/10

No identity system.
