🚄 Setup and run a Full Node

🥡 Full Node​

A full node prunes historical states: all finalized blocks' states older than a configurable number except the genesis block's state. This is 256 blocks from the last finalized one by default. A pruned node this way requires much less space than an archive node.

By specifying RPC endpoint parameters, node can be accessed over the WebSocket protocol, which can be used to access the underlying network and/or validator node. By default, you can access your node's RPC server from localhost (for example, to rotate keys or do other maintenance).

Configuration​

  • --base-path <PATH> (e.g /opt/manta/lib)
  • --chain manta

for version >= v4.6.0 (inclusive)

  • --rpc-port <PORT> (e.g 9944)
  • --rpc-cors <ORIGINS> (e.g all)
  • --rpc-max-connections <COUNT> (default: 100)
  • --rpc-methods <METHOD> (e.g safe)

for version < v4.6.0 (exclusive)

  • --ws-port <PORT> (e.g 9944)
  • --ws-max-connections <COUNT> (default: 100)
  • --rpc-port <PORT> (e.g 9933)
  • --rpc-cors <ORIGINS> (e.g. all)
  • --rpc-methods <METHOD> (e.g safe)

Example Command​

for version >= v4.6.0 (inclusive)

./manta --base-path /opt/manta/lib --chain manta --rpc-port 9944 --rpc-cors all --rpc-max-connections 100 --rpc-methods safe

for version < v4.6.0 (exclusive)

./manta --base-path /opt/manta/lib --chain manta --rpc-port 9933 --rpc-cors all --ws-max-connections 100 --ws-port 9944
