Community Powers of Tau Ceremony Survey
The Ethereum Foundation and members of the Ethereum community interested in zk-SNARKs will soon perform a trusted setup much like Zcash's Powers of Tau ceremony. The point of the ceremony is to distribute the generation of zk-SNARK cryptographic parameters among many participants in a way such that only 1 participant needs to be honest (i.e. dispose of the toxic waste) for the resulting parameters to be secure and trustworthy.
The results of the ceremony will be a public good as they can benefit all zk-SNARK circuits. (To be precise, this ceremony will be the first phase of a trusted setup, which can be common to any circuit; the second phase has to be circuit-specific.)
We are seeking views from the community about what level of trust they accept.
