State Sync Setup (optional)

Tip: If you have already started syncing and you want to start over with a state sync, you will need to delete all of the .db folders and the snapshots folder from ~/.layer/data folder:

# deletes chain data for resyncing
rm -rf ~/.layer/data/application.db; \
rm -rf ~/.layer/data/blockstore.db; \
rm -rf ~/.layer/data/cs.wal; \
rm -rf ~/.layer/data/evidence.db; \
rm -rf ~/.layer/data/snapshots
rm -rf ~/.layer/data/state.db
rm -rf ~/.layer/data/tx_index.db

1. Find a working TRUSTED_HEIGHT

Use the command:

export LATEST_HEIGHT=$(curl -s tellorlayer.com:26657/block | jq -r .result.block.header.height); \
export TRUSTED_HEIGHT=$((LATEST_HEIGHT-8000)); \ # current block - snapshot interval set by RPC
export TRUSTED_HASH=$(curl -s "tellorlayer.com:26657/block?height=$TRUSTED_HEIGHT" | jq -r .result.block_id.hash); \
echo $TRUSTED_HEIGHT $TRUSTED_HASH

This should output something like: 138807 0BCE40CD31D205453DA001780CBF765F3C64FCCB9DCB2F9825872D042780A288.

Copy this block and hash and keep it handy for the next step.

1. Edit config.toml:

Open your config file with your favorite text editor or nano:

nano ~/.layer/config/config.toml

Scroll or search the document and edit the variables as shown here:

# [statesync]
enable = true
#...
rpc_servers = "http://tellorlayer.com:26657,http://tellorlayer.com:26657"
trust_height = 137949
trust_hash = "F23E2ACAFF92FFEDE14CC9949A60F50E7C6D5A2D40BC9C838DF523944063294D"
trust_period = "168h0m0s"

Be sure to replace the trust_height and trust_hash with the block number and hash from step 1.

Exit nano with ctrl^x then enter y to save the changes.

1. Upgrade your binary to the current version:

# use binary v1.6.0
git checkout main && git pull && git checkout v1.6.0 && go build ./cmd/layerd

1. Start your node:

./layerd start
