OpenEthereum ETH1 node setup

OpenEthereum (used to be called Parity) is written in Rust and licensed under the GPLv3. The design goals are to be “the fastest, lightest, and most secure Ethereum client”.

Installing OpenEthereum

The OpenEthereum documentation explains how to download and install the client.

Dependencies

mbarrow@xray:~$ sudo apt-get install build-essential cmake libudev-dev

[mbarrow@xray ~]$ mkdir openethereum

[mbarrow@xray ~]$ cd openethereum/

[mbarrow@xray openethereum]$ wget https://github.com/openethereum/openethereum/releases/download/v3.1.0/openethereum-linux-v3.1.0.zip
