Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference.
This is a step-by-step guide, how to setup private Ethereum network.
We’ll set up a network and create two simple JSON-RPC clients in order to communicate with our Ethereum nodes.
