🎱 Privacy Pool

This is a proof-of-concept for a privacy pool implemented in SP1.

Depositing into the pool requires ~75k gas and simply consists of paying the pool contract with a set amount of ETH and appending a commitment hash to the deposits array.

Withdrawals are done by providing an SP1 proof which proves inclusion of the commitment in the deposits array. The array is proven using MPT account proof + storage proof and block hash is verified onchain using the BLOCKHASH opcode.

The withdrawal program can optionally prove inclusion of the commitment in a separate inclusion set to for example prove that the withdrawal is not associated with certain deposits in the pool. This concept is described in the Privacy Pools paper by Vitalik and others.

The CLI script can be used to generate a secret and commitment for deposits and generate a proof for withdrawals. No offchain indexing is required.

Relaying is supported as relayer address and fee are public inputs to the proof.
