A modular kernel designed for implementing blockchain-based digital currencies

CryptoKernel

CryptoKernel is a C++ library intended to help create blockchain-based digital currencies. It contains modules for key-value storage with JSON, peer-to-peer networking, ECDSA key generation, signing and verifying, big number operations, logging and a blockchain class for handling a Bitcoin-style write-only log. Designed to be object-oriented and easy to use, it provides transaction scripting with Lua 5.3, custom consensus algorithms (e.g Raft, Proof of Work, Authorised Verifier Round-Robin) and custom transaction types.

Building on Ubuntu 16.04

./installdeps.sh
make

Usage

See the source files in src/client/ for example usage. CryptoKernel ships with a Proof of Work coin built-in called K320 that works out of the box. For more information about the API check the documentation.

To launch CryptoKernel as K320 with its default setup, simply write:

./ckd

To get a list of command line RPC commands use:

./ckd help

To make ckd run in daemon mode use:

./ckd -daemon

There is also a GUI for CryptoKernel that runs client-side in a web browser available here: https://github.com/metalicjames/ckui
