Ink is Kraken's fifteen-month-old OP Stack L2 with a single sequencer and under ten million in TVL. Its quantum posture is whatever Ethereum and the Superchain decide it is. The unusual honesty here is that there is nothing chain-specific to evaluate.
Summary
Ink is Kraken's OP Stack L2 (Dec 2024), <$10M TVL, ~15 dApps. Centralized sequencer, Foundation-controlled upgrades. Quantum path entirely depends on Ethereum/OP Superchain. No PQC activity. Band 1 Unaware.
What the gates say
- Hybrid: FAIL. No hybrid plan on file.
- Evidence: PASS. Sources reconstructable by third party.

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 20 / 100
Standard OP Stack primitives.
ECDSA secp256k1 (inherited from Ethereum) · Keccak-256 · OP Stack fault proofs (hash-based)No PQC families deployed
No NIST PQC primitives deployed
2 HNDL Exposure 10 / 100
Inherits Ethereum ECDSA. Small TVL (<$10M) limits absolute risk.
15 months old. Limited cold-key horizon.
ECDSA Shor-breakable.
Standard TLS. No PQC KEM.
3 Metadata & Privacy Exposure 20 / 100
Pseudonymous EVM transparency.
Single Kraken sequencer. High concentration.
ETH<->Ink bridge + Kraken exchange correlation possible.
Non-private by design.
4 Migration Architecture 32 / 100
OP Stack is upgradable but Superchain-coordinated. Gated by Optimism/Ethereum direction.
Inherits Ethereum ERC-4337/EIP-7702 AA path.
Participated in permissionless fault proofs upgrade with Optimism.
Depends entirely on Ethereum/OP Superchain PQC path.

6 Supply Chain Vendor Readiness 8 / 100
7 Governance & Coordination 30 / 100
Centralized Kraken sequencer. No validator set.
Launched ahead of schedule, Optimism collaboration on permissionless fault proofs.
Kraken-incubated team + Ink Foundation. No named PQC lead.
Kraken has 13+ year exchange track record. No PQC precedent.
The X + Y vs Z inequality
X (data shelf life): 5-10 (young L2)
Y (migration time): 10-15 (gated by Ethereum/OP Superchain)
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 | 5% | 10% |
| arrives slowly post migration | 80% | 70% |
| arrives slowly mid migration | 30% | 25% |

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
Kraken exchange credibility is a governance positive but doesn't translate to PQC planning. Entirely dependent on Ethereum for crypto upgrades.
