Taiko's quantum posture is a copy of Ethereum's, and Taiko is honest about it. As a based, Type-1 equivalent rollup it inherits ECDSA secp256k1 and BN254 from L1 and has no independent PQ plan. The multi-prover scheme (SGX + ZK + guardian) is clever security, but none of it is post-quantum.
Summary
Taiko is a based, Type-1 equivalent rollup: by design it inherits Ethereum's crypto stack and migration timeline. Multi-prover (SGX + ZK + guardian) is a novel security posture but adds no PQ agility. No L2-specific PQ roadmap. Stage 0 baseline pinned to L1 dependency.
What the gates say
- Hybrid: FAIL. inherits Ethereum path only
- Evidence: PASS. Sources reconstructable by third party.
- Primitive naming: PASS. Named primitives at every scored sub-level.

Each dimension scores 0-100 internally; the weighted roll-up produces the QRI on the left. Open a row to read the sub-score detail.
1 Cryptographic Exposure 24 / 100
Based rollup Type-1: 100% Ethereum equivalence, inherits L1 primitives.
ECDSA secp256k1 (inherited from Ethereum) · Keccak-256 · BN254 (SNARK verification) · Halo2/PLONK-style proofs (multi-prover)All classical; no PQ family.
2 HNDL Exposure 20 / 100
Ethereum EOAs inherited; secp256k1 pubkeys exposed on first tx.
Launched mainnet 2024; smaller dormant surface.
Inherits Ethereum signature longevity risk; L2 does not add rotation.
Standard TLS; no PQC KEM.
3 Metadata & Privacy Exposure 22 / 100
Transparent ledger.
Based rollup: L1 proposers submit blocks, reducing sequencer concentration; RPC concentration at a few providers.
Canonical Ethereum<->Taiko bridge, LayerZero.
No shielded pools.
4 Migration Architecture 45 / 100
Type-1 equivalence: migration aligns with Ethereum; inherits ERC-4337/EIP-7702 AA path.
Same AA primitives as Ethereum; no L2-specific AA work.
Ontake/Pacaya upgrades executed; coordinated with L1.
No L2-specific hybrid plan; dependency on Ethereum L1 migration.
5 Deployment Execution 5 / 100
Zero PQC on mainnet. Mosca cap triggers.
No PQC code in taiko-geth or taiko-client.
Based rollup uses Ethereum proposers; no PQC validators.
No PQ milestones.
No claims, no washing.
6 Supply Chain Vendor Readiness 8 / 100
7 Governance & Coordination 32 / 100
Based rollup: Ethereum proposer set (permissionless); proving decentralized via multi-prover.
Two major upgrades Ontake/Pacaya; coordinated.
Named: Daniel Wang, Taiko Labs.
No adversarial precedent.
The X + Y vs Z inequality
X (data shelf life): 5-15 (inherited)
Y (migration time): 8-15 (gated by Ethereum L1 timeline)
Z10 (10% CRQC year): 2036 · Z50 (50%): 2041
Verdict: X+Y > Z (danger).
Four-scenario grid
| Scenario | Value preserved | Privacy preserved |
|---|---|---|
| quantum never | 100% | 100% |
| arrives suddenly pre migration | 12% | 10% |
| arrives slowly post migration | 60% | 30% |
| arrives slowly mid migration | 32% | 15% |

Based rollup Type-1: 100% Ethereum equivalence, inherits L1 primitives.
Supply chain snapshot
A chain's supply chain cannot migrate faster than its slowest dependency. Zero PQC roadmaps in any of the four categories is a structural blocker, not a lagging indicator.
Analyst notes on the scoring
Stage 0. PQ posture is exactly Ethereum's: no better, no worse. Scorecard reflects 'inherits everything' posture.
