About

This Safe Network SDKG module enables sections to create a Section Key without a trusted dealer. It is based on the Audited code from poanetwork's hbbft.

How it works

  • Participants know of each other's bls public key
  • Each create a Part and share it with the others
  • They check each Part and share their Ack over each Part
  • Participants share their set of AllAcks signed, and check that all the others have the same set
  • Once everyone has all the participants signatures over this set they generate the key

We differ from poanetwork's original implementation in that we require total participation: in the Part validation process, we require an Ack from everyone instead of just a threshold amount.
