This projects aims to code a MVP of a interactive DKG onchain, on a smart contract.

MVP #0: No Byzantine, simple Deals using BN254

To get the project started, we should consider there is no byzantine actors first (only honest but curious) and consider the setting where participants simply post their deals onchain (with encrypted shares still) but there is no “Complaint” phase.

This will help bootstrap the threshold operations MVP much faster.

The next step is to move to MVP #1.

MVP #1: EthDKG using BN254.

Motivation

• EthDKG provides a nice way to remove the justification phase AND have a publicly verifiable dispute phase. This make the protocol semi verifiable, at least in the pessimistic case which is what is most interesting.
• BN254 is the only pairing curve supported currently on Ethereum. Pairing curve enables more “fancy” use cases and optimizations.

Deliverables

There are multiple parts here to deliver:

Smart Contract Implementation

The smart contract is responsible for:

• Handling the list of active participants
• Activating the DKG with its different phases
