State sync

With our state sync services you will be able to catch up latest chain block in matter of minutes

Chain ID: passage-2 | Latest Version Tag: 2.4.0

State Sync allows a new node to join the network by fetching a snapshot of the application state at a recent height instead of fetching and replaying all historical blocks. Since the application state is generally much smaller than the blocks, and restoring it is much faster than replaying blocks, this can reduce the time to sync with the network from days to minutes.

Instructions

Stop the service and reset the data

sudo systemctl stop passage
cp $HOME/.passage/data/priv_validator_state.json $HOME/.passage/priv_validator_state.json.backup
passage tendermint unsafe-reset-all --home $HOME/.passage

Get and configure the state sync information

STATE_SYNC_RPC=https://passage-rpc.stakeandrelax.net:443
STATE_SYNC_PEER={{ peer }}
LATEST_HEIGHT=$(curl -s $STATE_SYNC_RPC/block | jq -r .result.block.header.height)
SYNC_BLOCK_HEIGHT=$(($LATEST_HEIGHT - 2000))
SYNC_BLOCK_HASH=$(curl -s "$STATE_SYNC_RPC/block?height=$SYNC_BLOCK_HEIGHT" | jq -r .result.block_id.hash)

sed -i \
  -e "s|^enable *=.*|enable = true|" \
  -e "s|^rpc_servers *=.*|rpc_servers = \"$STATE_SYNC_RPC,$STATE_SYNC_RPC\"|" \
  -e "s|^trust_height *=.*|trust_height = $SYNC_BLOCK_HEIGHT|" \
  -e "s|^trust_hash *=.*|trust_hash = \"$SYNC_BLOCK_HASH\"|" \
  -e "s|^persistent_peers *=.*|persistent_peers = \"$STATE_SYNC_PEER\"|" \
  $HOME/.passage/config/config.toml

mv $HOME/.passage/priv_validator_state.json.backup $HOME/.passage/data/priv_validator_state.json

Restart the service and check the log

sudo systemctl start passage && sudo journalctl -u passage -f --no-hostname -o cat
