Chain ID: crescent-1 | Current Node Version: v4.2.0
app.toml settings related to state-sync is as follows.
This is for you information only. You do not need to follow the same
setup on your node.
# Prune Type pruning = "custom" # Prune Strategy pruning-keep-every = 2000 # State-Sync Snapshot Strategy snapshot-interval = 2000 snapshot-keep-recent = 5
Our state-sync RPC server for Crescent is:
We assume that you use Cosmovisor to manage your node. If you do not use Cosmovisor, you will need to customize the following instruction slightly.
Create a reusable shell script such as
following code. The code will fetch important state-sync information
(such as block height and trust hash) from our server and
config.toml file accordingly.
#!/bin/bash SNAP_RPC="https://crescent-rpc.polkachu.com: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/.crescent/config/config.toml
Grant user the privilege to execute script and then run the script:
chmod 700 state_sync.sh ./state_sync.sh
Stop the node:
sudo service crescent stop
Reset the node:
# On some tendermint chains crescentd unsafe-reset-all # On other tendermint chains crescentd tendermint unsafe-reset-all --home $HOME/.crescent --keep-addr-book
Restart the node:
sudo service crescent start
If everything goes well, your node should start syncing within 10 minutes.
ALTERNATIVE ROUTE: We also have Crescent Snapshot Service to help you bootstrap a node.
First, visit our state-sync server landing page to ensure it is not down.
Second, add Polkachu's state-sync server as your peer. You can find Polkachu's peer info here.
Make sure that you use the latest version of the chain node when you state-sync.
State-sync can be flaky at times. Join our Discord Server if you have any issues. Happy State-Syncing!
