d. archive node tutorial
Archive nodes save the raw historical state of the blockchain for full nodes to reference. These require a large amount of storage.
Solution
To setup an archive node, you will need to customize your nodes pruning settings. To do this, we can run the following command to update the setting located in ~/.terp/config/app.toml:
sed -i -e "s/^pruning *=.*/pruning = \"nothing\"/" $HOME/.terp/config/app.toml
now your node will keep the entire state saved, without pruning.
Sync From Genesis Block Archive
To sync from block height 1, you will need to ensure the node uses the proper versioning of terp-core dependent on the block height:
| Blocks From | Blocks To | Terp-Core Version |
|---|---|---|
0 | 2,847,602 | barberry |
2,847,603 | 3,039,061 | v2 |
3,039,062 | 3,341,663 | v3 |
3,341,664 | current | v4 |
Archive Peers
PEERS="[email protected]:26656"
sed -i -e "/^\[p2p\]/,/^\[/{s/^[[:space:]]*persistent_peers *=.*/persistent_peers = \"$PEERS\"/}" $HOME/.terp/config/config.toml
