Semaphore Roadmap for Ethereum

on YouTube ↗24m

" summary

Live recording from Zcon1 outlines a Semaphore-based roadmap for privacy on Ethereum, describing a working fixed-denomination mixer that uses Merkle trees, nullifiers and zk-SNARK-style Merkle-root membership proof to unlink deposits and withdrawals, forces wait windows to mitigate timing heuristics, and pays a small relayer fee for gas. It also presents a coercion‑resistant voting design where users publish encrypted votes processed on-chain by an operator with SNARK-verified updates and key-rotation to prevent buyers of receipts, and discusses attacks (trusted hardware, MPC) and mitigations (proof-of-work, MPC pools).
