Powers of Tau
This is a multi-party computation (MPC) ceremony which constructs partial zk-SNARK parameters for all circuits up to a depth of 221. It works by taking a step that is performed by all zk-SNARK MPCs and performing it in just one single ceremony. This makes individual zk-SNARK MPCs much cheaper and allows them to scale to practically unbounded numbers of participants.
This protocol is described in a forthcoming paper. It produces parameters for an adaptation of Jens Groth's 2016 pairing-based proving system using the BLS12-381 elliptic curve construction. The security proof relies on a randomness beacon being applied at the end of the ceremony.
This is a work in progress.
