Ledgerium Core

Ledgerium Blockchain provides Geth as the core blockchain protocol client to run the Ledgerium Node and to interact with the Ledgerium Blockchain. Ledgerium Blockchain is inspired by J.P. Morgan's Quorum Protocol (Based on the Ethereum Foundation's Ethereum Protocol) and utilises IBFT (Istanbul Byzantine Fault Tolerant) consensus mechanism for both testnets and mainnet implementations. The Ledgerium Foundation have tried to keep the source as close to the original source code as possible.

Please refer to our releases link


It is recommended to use the release branches. Advanced developers may choose at their discretion.

Building the source

  • Please read the installation instructions and prerequisites on the Ledgerium.

  • Building 'geth' requires Golang (version 1.11 or later) and a make tool. You can install them using your package manager. Once the dependencies are installed, please follow below commands

git clone https://github.com/ledgerium-io/ledgeriumcore.git
cd ledgeriumcore
make geth
make all - //To build the full suite of utilities
