What is Perpetual Powers of Tau?

The Perpetual Powers of Tau ceremony is a multi-party computation protocol that generates cryptographic parameters required for zk-SNARK systems. These parameters enable zero-knowledge proofs, allowing users to verify computations without revealing the underlying data.

Community-Driven Security

As long as one participant behaves honestly and destroys their secret randomness ('toxic waste'), the entire setup remains secure. No single entity controls the final parameters.

BLS12-381 Elliptic Curve

Built on the industry-standard BLS12-381 curve, supporting circuits up to 2^23 constraints (~8 million), enabling complex zero-knowledge applications.

Sequential Contribution Process

Participants download challenge files (~9GB), add secret randomness, generate response files, and permanently destroy their secret inputs to ensure security.

Public Beacon Finalization

After all contributions, a public beacon is applied to ensure security even if participants collude, providing an additional layer of trustlessness.

How the Ceremony Works

1

Registration

Interested contributors register through the official form and join the community Discord channel to coordinate participation.

2

Download Challenge

Participants download challenge files (~9GB each) containing the current state of the ceremony parameters.

3

Contribute Randomness

Using their local machine (16GB+ RAM recommended), contributors add secret randomness to extend the cryptographic parameters over a 3-4 hour window.

4

Upload & Verify

Response files are uploaded and verified by the community. Contributors permanently destroy their secret inputs to maintain security.

5

Receive Rewards

Verified contributors receive ADA rewards as appreciation for strengthening the Cardano ecosystem. Voluntary participation is also welcomed.
