0G Node State-Sync

Instruction

Create a reusable shell script such as state_sync.sh with the following code. The code will fetch important state-sync information (such as block height and trust hash) from our server and update your config.toml file accordingly.

shell
#!/bin/bash

SNAP_RPC="https://0g-rpc.murphynode.net:443"

LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height); \
BLOCK_HEIGHT=$((LATEST_HEIGHT - 2000)); \
TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)

sed -i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1true| ; \
s|^(rpc_servers[[:space:]]+=[[:space:]]+).*$|\1\"$SNAP_RPC,$SNAP_RPC\"| ; \
s|^(trust_height[[:space:]]+=[[:space:]]+).*$|\1$BLOCK_HEIGHT| ; \
s|^(trust_hash[[:space:]]+=[[:space:]]+).*$|\1\"$TRUST_HASH\"|" $HOME/.0gchain/config/config.toml

Grant user the privilege to execute script and then run the script:

shell
chmod 700 state_sync.sh
./state_sync.sh

Stop the node:

shell
sudo systemctl stop 0gchaind

Reset the node:

shell
# On some tendermint chains
0gchaind unsafe-reset-all

# On other tendermint chains
0gchaind tendermint unsafe-reset-all --home $HOME/.0gchain --keep-addr-book

Restart the node:

shell
sudo systemctl start 0gchaind
