zkLink is an L3 PLONK-on-BN254 rollup stacked on top of other rollups. Every layer underneath has to migrate first. That is a dependency chain that gets longer the more you think about it, not shorter.

Summary

zkLink is an aggregated L3 zkEVM stacked on Ethereum L2s, using PLONK on BN254. All crypto is Shor-breakable. Centralized sequencer, brief track record. Stacked-dependency model means migration is contingent on both Ethereum and each underlying L2 migrating first.

The X + Y vs Z inequality

X (data shelf life): 3-8

Y (migration time): 6-12 (L3 stacked dependencies)

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

Stage 0. L3 stacking amplifies migration dependency chain; PQ posture is the weakest point across the stack.
