Could Consensys host a trust setup ceremony to build known curves SRS, such as BN254/BLS12377+BW6761/ BLS24-315+BW6-672/BLS12381?

This SRS will be public goods for zk-snark.

Currently (or as part of its roadmap) Consensys, for the Linea zkEVM, uses transcripts from public trusted setup ceremonies. For:

• BN254: Ignition ceremony from Aztec,
• BLS12-377: ceremony from Aleo,
• BW6-761: Plumo ceremony from Celo.

There are setups for BLS12-381 but their use is not part of Consensys roadmap. For BLS24-315 and BW6-762, indeed I don't believe there are corresponding trusted public setups. gnark has already all the tools to conduct MPC ceremonies #515 (contribution from Binance @HSG88) following [BG19] for all supported curves in gnark-crytpo #563. Also some independent teams, for the Ethereum KZG ceremony, used gnark to implement a kzg CLI interface https://github.com/jsign/go-kzg-ceremony-client and a browser interface https://www.dogekzg.com/. We're happy to help if you want to take the lead on this SRS project.

@yelhousni Do you know where can I find the BW6-761 SRS generated in Plumo ceremony? I try to search in google but found nothing.

You can find the generated transcript (for phase1 aka powers of tau) here: https://console.cloud.google.com/storage/browser/plumoceremonyphase1
