ibet-Core

ibet-Core is the node client for ibet Network, developed from a GoQuorum fork and maintained independently by BOOSTRY.

Overview

ibet-Core started as a fork of GoQuorum, which itself is based on go-ethereum. Since the fork, it has been developed independently for ibet Network rather than tracking new GoQuorum releases. It remains an EVM-compatible blockchain node client and selectively incorporates go-ethereum execution-layer improvements, dependency updates, and ibet Network-specific features needed for efficient and secure operation.

The version control policy of this project follows that of ibet-Network.

Features

ibet-Core is developed on the GoQuorum baseline adopted by this project and includes the following enhancements:

• The default block generation interval is set to 1 second.
• Go 1.25 is supported, with third-party packages updated from a security perspective.
• Selected go-ethereum execution-layer improvements are incorporated where they benefit ibet Network.
• Project-specific fixes and operational improvements are maintained independently after the GoQuorum fork.
• Added precompile for secp256r1 signature verification (EIP-7951).
• Added precompile for BLS12-381 curve operations (EIP-2537).
• Added support for AWS Secrets Manager / KMS based node key management.

Building ibet-Core

Building ibet-Core requires both a Go (version 1.25) and a C compiler. You can install them using your favourite package manager. Once the dependencies are installed, run

make geth

or, to build the full suite of utilities:

make all

AWS node key management

For AWS Secrets Manager / KMS based node key setup, see docs/aws-nodekey.md.
