Blast is a zombie-chain on ECDSA secp256k1 that already failed its own stress test. 97% of the TVL has left, a node failure froze 12K users, and the crypto migration plan is to hope Ethereum drags it along. There is no coordination capability left to migrate anything.
Summary
Blast is an Optimistic Rollup that collapsed 97% from $2.7B TVL peak to ~$55M zombie status. Custom OP Stack fork with native yield mechanism. Zero PQC activity; quantum migration entirely gated by Ethereum. March 2025 node failure froze 12K users, exposing fragility.

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
Optimistic rollup. Native yield via DeFi integration adds no new crypto primitives.
ECDSA secp256k1 (inherited Ethereum) · Keccak-256 · BLS12-381 (Ethereum L1 settlement)No PQC families
No NIST PQC
2 HNDL Exposure 12 / 100
Zombie-chain status limits fresh key exposure. EOA pubkeys still visible for all past users.
Young chain (March 2024); frozen 12K users during March 2025 incident.
ECDSA signatures Shor-breakable.
Standard TLS.
3 Metadata & Privacy Exposure 10 / 100
Transparent EVM.
Centralized sequencer (Blast team).
Native bridge with DeFi yield integration; correlation visible on Ethereum L1.
No shielded pool.
4 Migration Architecture 28 / 100
Custom OP Stack fork. Native yield complexity adds migration friction.
Inherits ERC-4337 infrastructure.
Limited upgrade history; March 2025 node failure incident.
No hybrid plan; depends entirely on Ethereum L1.
5 Deployment Execution 2 / 100

6 Supply Chain Vendor Readiness 4 / 100
7 Governance & Coordination 18 / 100

97% TVL collapse signals weak coordination capability.
The X + Y vs Z inequality
X (data shelf life): 3-8 (zombie-chain context — signatures exist but activity collapsed)
Y (migration time): 10-15 (dependent on Ethereum L1 migration)
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 | 10% | 5% |
| arrives slowly post migration | 70% | 60% |
| arrives slowly mid migration | 35% | 20% |

Optimistic rollup. Native yield via DeFi integration adds no new crypto 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
Zombie-chain status — Preskill cap applied across most dims. Weak governance coordination likely means PQC migration will only occur if Ethereum forces it.
