🚄 Setup and run a Archive Node

🥡 Archive Node​

An archive node keeps all the past blocks and their states. An archive node makes it convenient to query the past state of the chain at any point in time. Finding out what an account's balance at a particular block was or which extrinsics resulted in a specific state change are fast operations when using an archive node. However, an archive node takes up a lot of disk space.(For Polkadot's 20 millionth block, it took up around 328 GB.)

Similar to full node rpc parameters can also be specified serve the archive node as rpc node

Configuration​

  • --pruning archive
  • --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)

Example Command​

for version >= v4.6.0 (inclusive)

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