TetzelCoin is a blockchain-based confessional that forgives you of your sins. Users confess their sin and pay what they believe their sin is worth in ether. In return, they receive SIN tokens in proportion to how much they gave, providing them with proof of their forgiveness. All sins are publicly and immutably recorded on the Ethereum blockchain. 85% of the proceeds from TetzelCoin went to RIP Medical Debt, a non-profit that buys and cancels medical debt. Named after Protestant Reformation-era figure Johann Tetzel, the project launched on October 31st, 2017 (the 500th anniversary of Reformation Day) and ran through December 31st, 2017.

TetzelCoin is an exploration on spirituality, technology and debt. You can read the full artist statement here.

The artifacts of the project included a website, blockchain confessional app, white paper, in person event, paper wallets, and a proposed installation for another live performance.
