Ethereum Social Contract

This repository contains the PrivacyPool contract which enables private ERC20 transfers while maintaining legal compliance by requiring the divulgence of secrets to a trusted committee that will respond to requests from law enforcement orders.

If the backend server is not available, deposited funds may be recovered by performing a public withdrawal that does not break the transfer link.

TAZ contracts use the latest version of the Semaphore.sol contract, deployed on the Goerli testnet. The web app uses Next.js and allows users with a valid Semaphore ID to join the TAZ group and generate Semaphore proofs to post anonymous questions and answers, or to make art. Proofs related to the Q&A part are validated on-chain, while proofs related to artworks are validated off-chain and final canvases are posted as NFTs. Users can also vote anonymously for their favorite artworks.

⚠️ The TAZ apps are experimental and the code is not well tested. For more information visit taz.appliedzkp.org or see our Notion site.
