wget https://github.com/BitCannaGlobal/bcna/releases/download/v1.5.3/bcna_linux_amd64.tar.gz
tar zxvf bcna_linux_amd64.tar.gz
./bcnad version
 >> result should be `1.5.3`

### Option 2. Compile from source

git clone https://github.com/BitCannaGlobal/bcna.git
cd bcna
# git fetch if already cloned
git checkout v1.5.3
make build  ## mv  build/bcnad $(which bcnad)  > manually to service path
make install ## Optional: it install in $GOBIN

## Prepare (Cosmovisor) or replace (manually) any previous version with this `v1.5.3`

### For Cosmovisor:
> You can perform this step before chain halts.

#### Install/update the last version of Cosmovisor v1.4
* [check this doc to replace BCNAD service by Cosmovisor](https://github.com/BitCannaGlobal/bcna/blob/main/2.3.cosmovisor.md)

go install cosmossdk.io/tools/cosmovisor/cmd/cosmovisor@v1.4.0

Now prepare the folders and binary

mkdir -p ${HOME}/.bcna/cosmovisor/upgrades/trichomemonster-ica/bin/

* If you downloaded it

    mv bcnad ${HOME}/.bcna/cosmovisor/upgrades/trichomemonster-ica/bin/

Check if everything works properly:

cosmovisor version
cosmovisor run version # before upgrade should be: v1.4.5; after v1.5.3
sudo service cosmovisor restart && sudo journalctl -fu cosmovisor -o cat #check the logs

### For BCNAD daemon:
> When chain halts: Replace any previous version with this `v1.5.3`

    sudo mv build/bcnad  $(which bcnad)
