Relay System for BTP 2.0

Introduction

This is a reference relay implementation for BTP 2.0 protocol.

Target chains

  • ICON (BTP Block)
  • Hardhat (EVM-compatible chain)

Terminologies

Word Description
BTP Blockchain Transmission Protocol, see ICON BTP Standard.
BTP Message A verified message which is delivered by the relay
Service Message A payload in a BTP Message
Relay Message A message including BTP Messages with proofs for that, and other block update messages.
Network Address A string to identify blockchain network
ex) 0x1.icon
BTP Address A string of URL for locating an account of the blockchain network
ex) btp://0x1.icon/cx87ed9048b594b95199f326fc76e76a9d33dd665b

Components

  • BTP Message Center (BMC) - smart contract

    • Receive BTP messages through transactions.
    • Send BTP messages through events.
  • BTP Message Verifier (BMV) - smart contract

    • Update blockchain verification information
    • Verify delivered BTP message and decode it
  • BTP Service Handler (BSH) - smart contract

    • Handle service messages related to the service.
    • Send service messages through the BMC
  • BTP Message Relay (BMR) - external software (implemented by this repository)

    • Monitor BTP events
    • Gather proofs for the events
    • Send BTP Relay Message

Getting Started

  1. git clone https://github.com/icon-project/btp2.git --recurse-submodules
  2. cd btp2
  3. make relay
