We recently announced our open sourced protocol on Tornado Cash: Proof of Innocence
It gained a lot of attention from the Ethereum ecosystem, including Vitalik Buterin, The Block, Bankless, and more. You can follow our projects and products on our website or twitter.
Proposal
We are seeking a grant of $100K to develop and deploy a demo version of Privacy Pools v1, an innovative privacy solution combining the capabilities of Tornado Nova and Proof of Innocence. The project will include the development of circuit code, smart contracts, JavaScript libraries/scripts, and a demo user interface. Our target is to deploy Privacy Pools v1 to a testnet by the end of Q1 2024.
Note from Ameen - Funding for this proposal will be milestone based. $50K will be awarded first, and upon completion of the circuits & contracts, the remaining $50K will be rewarded.
Grant Proposal is for $50K = 28.4 ETH + 20% Volatility Buffer = 34 ETH(remainder to be returned)

Roadmap
Circuits(April 1st)
Step1: Research on(Halo2, Nova, Plonky2)(Expected time 1 month)
Step2: Writing the circuit for single transaction(Only single deposit and withdrawal)(Expected time 1 month)
Step3: Writing recursion(Expected time 1 month)
Step4: Tests(Expected time 1 month)
Contracts
Deployment of tornado nova contracts on testnet
Js script(Expected time 1 month)
Scripts for deposit, withdrawal, internal transaction
Fetching onchain data for circuit inputs
Generate and verify recursive proof of exclusion
UI(Expected time 2 month)
Basic tornado nova features
Prove innocence tab where the user can select deposits to exclude and creates a proof for all the past transactions
Verify exclusion zk proofs
Explorer for viewing“withdrawal exlusion proofs”
Future Work
outside the scope of this grant:
Quarantine
this is where some sanctioned address sends you internal transaction but you never withdraw that money and you also want to prove that you won't be using that money
Audits
Sanctioned addresses listing
Note from Ameen - working on this with a separate team
