MEGAETH · rollup-L2 · QRI 8 · BAND 1 Unaware Hybrid FAIL · Stage 0 · Washing 1x

MegaETH is selling 35,000 transactions a second. Post-quantum signatures are roughly a hundred times larger than ECDSA. You cannot advertise throughput AND avoid the signature question. At some point those two numbers meet, and nobody on the MegaETH side has shown the calculation.

Summary

MegaETH is a very young high-performance L2 (~35K TPS testnet), Vitalik-backed. Mainnet approximately 6 weeks old as of evaluation. Standard ECDSA + EigenDA stack, no PQC activity. High-throughput design creates potential headwind for PQ signature adoption (larger sigs consume bandwidth). Band 1 Unaware, very low confidence due to nascent state.

What the gates say

Hybrid: FAIL. No hybrid plan on file.
Evidence: COND. Reconstruction gap on at least one sub-score.

The X + Y vs Z inequality

X (data shelf life): 3-7 (very young chain)

Y (migration time): 10-15 (L2 + EigenDA dual-dep)

Z10 (10% CRQC year): 2036 · Z50 (50%): 2041

Verdict: X+Y > Z (danger).

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

The high-throughput L2 architecture is a migration tension point: larger PQ signatures (ML-DSA ~3KB, SLH-DSA ~8KB) may conflict with 35K TPS bandwidth targets unless aggressive aggregation is deployed. No PQC roadmap found.
