ethresear.ch

Faster, Aggregatable and Quantum Safe Privacy Pools

In briefFaster, aggregatable, quantum-safe privacy pools (Tornado Cash-style)

SummaryThe authors port a Tornado Cash-style privacy pool to Flock, a post-quantum binary-field SNARK, using SHA-256 for the Merkle tree and nullifier hashing. They report proving a depth-32 withdrawal in under 30 ms and describe recursive aggregation of withdrawals. They also propose a recovery protocol in which wallets derive note secrets from a seed, so existing pools can survive a discrete logarithm break.

Delving Bitcoin

Variable payout amounts for BABE (as applied to Lichen)

In briefVariable payout amounts for BABE, applied to Lichen

SummaryThis Delving Bitcoin discussion explains how the BABE scheme uses witness encryption so a Bitcoin contract unlocks only when someone holds a valid Groth16 proof. The author proposes a way to make the payout amount variable rather than fixed at contract setup. The example for Lichen shows how the verifier and prover exchange signatures on the withdrawal amount.
