ENDGAME: HOW WE USE ZK TO SECURE MEGAETH

Summary from the TLDR Crypto newsletter

Optimistic rollups hinge on fraud proofs, but today's interactive bisection games are slow, costly, and vulnerable to griefing. MegaETH replaces that with non‑interactive ZK fraud proofs: a challenger submits a single zkVM proof that the proposed state is invalid, $100 only when fraud exists. The chain keeps a 7‑day detection window, yet once challenged, finality is restored in ~1 hour, and dishonest sequencers are slashed, eliminating stall attacks. EigenDA supplies the data needed to reconstruct blocks, ensuring anyone can verify and generate proofs, strengthening an efficient, scalable, onchain security model.
