Celestia Services

RPC Endpoint

Our state-sync RPC server for Celestia is:

https://celestia-mainnet.stakingcabin.com:443

Our State-Sync Server Setup

Our 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"

# These are applied if and only if the pruning strategy is custom.
pruning-keep-recent = "3000"
pruning-interval = "10"

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.

#!/bin/bash

STATE_SYNC_RPC=https://celestia-mainnet.stakingcabin.com:443
LATEST_HEIGHT=$(curl -s $STATE_SYNC_RPC/block | jq -r .result.block.header.height)
BLOCK_HEIGHT=$((LATEST_HEIGHT - 2000))
TRUST_HASH=$(curl -s "$STATE_SYNC_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)

echo -e "Modifying $HOME/.celestia-app/config/config.toml based on the following values:"
echo -e "RPC Address:          $STATE_SYNC_RPC"
echo -e "Latest Block Height:  $LATEST_HEIGHT"
echo -e "Sync Block Height:    $BLOCK_HEIGHT"
echo -e "Trust Hash:           $TRUST_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 = $BLOCK_HEIGHT|" \
  -e "s|^trust_hash *=.*|trust_hash = \"$TRUST_HASH\"|" \
  $HOME/.celestia-app/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 systemctl stop celestia

Reset the node:

# On some tendermint chains
celestia-appd unsafe-reset-all

# On other tendermint chains
celestia-appd tendermint unsafe-reset-all --home $HOME/.celestia-app --keep-addr-book

Start node:

sudo systemctl start celestia

If everything goes well, your node should start syncing within 10 minutes.
