snapshot-keep-recent = 2

Our state-sync RPC server for Bitcanna is:

https://bitcanna-rpc.stakeme.io

One line script

wget https://raw.githubusercontent.com/ProNodes11/NodeGuides/main/StateSync/bitcanna-state-sync.sh && chmod +x bitcanna-state-sync.sh && ./bitcanna-state-sync.sh

Stop the node

sudo systemctl stop bcnad

Reset the node

bcnad tendermint unsafe-reset-all --keep-addr-book

Change config file

SNAP_RPC=https://bitcanna-rpc.stakeme.io
LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height); \
BLOCK_HEIGHT=$((LATEST_HEIGHT - 1000)); \
TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)
echo $LATEST_HEIGHT $BLOCK_HEIGHT $TRUST_HASH
sed -i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1true| ; \

s|^(seeds[[:space:]]+=[[:space:]]+).*$|\1\"\"|" $HOME/.bcna/config/config.toml

Start the node

sudo systemctl restart bcnad

And check logs

sudo journalctl -fu bcnad -o cat

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

If you are experiencing difficulty connecting to the state-sync server, please check the status of our RPC node to rule out any downtimes.

In case you are able to connect, but encountering AppHash errors, ensure that you are using the most recent version of the chain node during state-sync.

If you continue to experience issues, please do not hesitate to reach out to us in our Telegram chat for further assistance. Keep in mind that occasional unavailability of state-sync is a possibility
