Function run

pub async fn run<R, S>(
    setup: S,
    seed: Seed,
    relay: R,
    s_i_0: Scalar,
    public_key: ProjectivePoint,

) -> Result<Keyshare, KeygenError>
where

    R: Relay,

Migrates key shares from other ECDSA threshold protocols to DKLS23 format.

This function performs the migration of existing key shares to the DKLS23 protocol. It uses the same underlying logic as the key refresh process but with a hardcoded initial secret share value. The migration preserves the original public key and chain code while updating the internal representation to the new protocol format.

Type Parameters

• R - A type implementing the Relay trait for message communication
• S - A type implementing the KeygenSetupMessage trait for protocol setup

Arguments

• setup - The protocol setup configuration
• seed - The random seed for key generation
• relay - The message relay for communication between parties
• s_i_0 - The initial additive secret share value from the existing protocol
• public_key - The public key to be preserved during migration
• root_chain_code - The root chain code to be preserved during migration

Returns

• Ok(Keyshare) - The migrated key share in DKLS23 format
• Err(KeygenError) - If the migration process fails

Errors

This function may return the following errors:

• KeygenError::AbortProtocol - If the protocol is aborted by a participant
• KeygenError::SendMessage - If there’s an error sending messages
• Other KeygenError variants for various protocol failures
