@hsuite/dkg-types

A comprehensive type system and model definitions for Distributed Key Generation (DKG) operations in the HSuite ecosystem.

Overview

The @dkg-types library provides a robust set of TypeScript interfaces and model implementations for managing distributed key generation processes. It serves as the foundational type system for DKG operations, ensuring type safety and consistency across the HSuite platform.

Core Components

Interfaces (IDKG Namespace)

• NetworkClusterStatus: Enum defining possible cluster states

  • BUILDING: Initial setup phase

  • ROTATING: Member addition/removal phase

  • BANNING: Problematic member removal

  • CONTRIBUTIONS_READY: Ready for member contributions

  • READY: Fully operational state

• IShamirSecretShare: Interface for Shamir's Secret Sharing implementation

• IMemberShare: Interface for managing member share distribution

• INode: Interface for DKG network participants

• IMember: Interface for DKG protocol members

• ICluster: Interface for DKG cluster management

• IPayload: Interface namespace for DKG protocol messages

Models (DKG Namespace)

• ShamirSecretShare: Implementation of Shamir's Secret Sharing scheme

  • Secure secret splitting

  • Threshold-based reconstruction

  • Share integrity validation

• MemberShare: Implementation for member share management

  • Share distribution tracking

  • Ownership management

  • Integrity validation

• Node: Implementation for network participants

  • Node identification

  • Network addressing

  • Verification vector management

• Member: Implementation for protocol participants

  • Share management

  • Key generation

  • Protocol state management

• Cluster: Implementation for DKG cluster coordination

  • Member coordination

  • Threshold management

  • State synchronization

• Payload: Implementation namespace for protocol messages

Features

• Type-safe DKG operations

• Comprehensive protocol state management

• Threshold cryptography support

• Secure share distribution

• Member coordination

• Protocol message handling

• Verification vector management

Usage

import { IDKG, DKG } from '@dkg-types';

// Create a new node
const node: IDKG.INode = {
  operator: '0x123abc...',
  id: 'node-123',
  sn_id: 'smartnode-456',
  vvec: ['vvec1', 'vvec2']
};

// Initialize a cluster
const cluster: IDKG.ICluster = {
  networkId: "network-123",
  members: [],
  memberships: [],
  groupsVvec: ["vvec1", "vvec2"],
  threshold: 3
};

// Create a member instance
const member: IDKG.IMember = {
  dkgId: 'dkg-789',
  membersShares: [],
  verificationVector: ['vv1', 'vv2'],
  receivedShares: [],
  secretKeyShare: 'sk-123',
  secretKeyShamir: ['ss1', 'ss2'],
  shamirSecretShares: []
};
