[BUG] Signing requires all authorities to be online #679

Closed 1xstj closed 1 year ago

1xstj commented 1 year ago

Describe the bug Consider a DKG network with t=3 and n=5. Ideally if one of the nodes crashes/does not respond, the signing should progress since we still have t+1 (4) authorities online and signing.

To Reproduce Steps to reproduce the behavior:

  1. Start a local network with 3-of-5 authorities
  2. Wait until the genesis keygen is completed and atleast one proposal is signed
  3. Kill one of the authority nodes, the network should have 4-of-5 authorities now
  4. Block production continues, but any proposals send to the DKG are not signed.

Expected behaviour Proposals are signed as long as t+1 authorities are online.
