Alkia IT Services

Our state-sync RPC server for Bitcanna is: http://bitcanna.alkia.net:26657

​

Cosmovisor is recommended to manage your node. If you do not use Cosmovisor, you may need to customize the next instruction.

​

Copy our state_sync.sh and give it the necessary right (chmod 700 state_sync.sh).

 

This script grabs important state-sync information (such as block height and trust hash) from our server and update your config.toml file accordingly.

​

The code of state_sync.sh is:

​

#!/bin/bash SNAP_RPC="http://bitcanna.alkia.net:26657"

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/.bcna/config/config.toml

​

Now run the script:

 ./state_sync.sh

​

Stop the node:

 sudo service bcnad stop

​

Reset the node:

 bcnad tendermint unsafe-reset-all --home $HOME/.bcna --keep-addr-book

​

Restart the node:

 sudo service bnad start
