Struct dkg_gadget::signing_manager::SigningManager

pub struct SigningManager<B: Block, BE, C, GE> { /* private fields */ }

The signing manager is triggered each time a new block is finalized. It will then start a signing process for each of the proposals. SigningManagerV2 uses 1 signing set per proposal for simplicity.

The steps: Fetch the current DKG PublicKey pk Fetch all the Unsigned Proposals from on-chain unsignedProposals for each unsinged proposal unsingedProposal do the following: create a seed s where s is keccak256(pk, fN, keccak256(unsingedProposal)) you take this seed and use it as a seed to random number generator. generate a t+1 signing set from this RNG if we are in this set, we send it to the work manager, and continue. if we are not, we continue the loop.

pub async fn on_block_finalized( &self, header: &B::Header, dkg_worker: &DKGWorker<B, BE, C, GE> ) -> Result<(), DKGError>

This function is called each time a new block is finalized. It will then start a signing process for each of the proposals.

pub async fn update_local_signing_set_state(&self, update: SigningResult)

Whenever a signing protocol finishes, it MUST call this function
