How to Run a FullNode on Metatime MetaChain

How to Run a FullNode on Metatime MetaChain

Requirements

  • 8 cores of CPU and 16 GB of memory (RAM)

  • A broadband Internet connection with upload/download speeds of 50 Mbit/S

  • 128 GB of free disk space, solid-state drive(SSD)

Steps to Run a FullNode:

  • Download the pre-build binaries (Follow the instructions below)

#Linux

wget https://github.com/Metatime-Technology-Inc/metachain/raw/v2.2/geth/geth_linux
mv geth_linux geth
chmod -v u+x geth

  • Download the config files (Download genesis.json and config.toml)

# Linux

wget https://raw.githubusercontent.com/Metatime-Technology-Inc/metachain/v2.2/geth/config.toml
wget https://raw.githubusercontent.com/Metatime-Technology-Inc/metachain/v2.2/geth/genesis.json

  • Write genesis state locally

# Linux

./geth --datadir data init genesis.json

You could see the following output:
