how to generate MPC keys?

Closed this issue · 5 comments

I was setting up the full stack and ran into an issue running the MPC node against a regtest environment.
When I run cargo run -- start-committee-node I get

error: the following required arguments were not provided:
  --key-path <KEY_PATH>
  --publickey-package-path <PUBLICKEY_PACKAGE_PATH>

How do I perform DKG? Can I generate new keys or should I always be using the keys defined in the container?

Thanks

There is this command which you should probably run.

for example:

cargo run -- generate-committee --num 5 --threshold 3 --output-dir ./committee

This will create the keys for all 5 nodes.

This looks like a trusted key generation, not a DKG (I believe).

yes this is generation of keys via a trusted dealer, we haven't exposed the DKG stuff yet but this is planned work

@0xBEEFCAF3 have you had any luck creating the MPC keys? Shall we close this issue?

yes! Thank you for your help!
Closing.
One more thing. If you guys need a hand with the DKG things lmk or point me to an issue. I am currently developing it for another project with the same frost lib and would be happy to contribute here.

Thanks again 👍
