Please replace current v1.4.2 or v1.4.3-patch by v1.4.3-2-g9f1b06d

• No chain halt (consensus) required
• Apply it ASAP

Stop your current daemon (bcnad or Cosmovisor)

sudo service bcnad stop || sudo service cosmovisor stop

Make a copy of the bd files:

copy -R $HOME/.bcna/data $HOME/.bcna/data_update

Another important step to make: add this text to .bcna/config/app.toml

# IAVLDisableFastNode enables or disables the fast node feature of IAVL. 
# Default is true.
iavl-disable-fastnode = false

Instructions for compile the source

git clone https://github.com/BitCannaGlobal/bcna-patch.git
cd bcna-patch
git checkout 1.4.3-2-g9f1b06d
make build
build/bcna version 
 >> should be `1.4.3-2-g9f1b06d` 

For Cosmovisor:

cp ~/.bcna/cosmovisor/current/bin/bcnad ~/.bcna/cosmovisor/current/bin/bcna_downgrade #for fast downgrade 
mv build/bcnad  ~/.bcna/cosmovisor/current/bin/
sudo service cosmovisor restart
sudo journalctl -fu cosmovisor #check the logs

### For BCNAD daemon:

sudo cp $(which bcnad) ~/bcna_downgrade #for fast downgrade
sudo mv build/bcnad $(which bcnad)
sudo service bcnad restart
sudo journalctl -fu bcnad #check the logs

Instructions for download (bcnad & cosmovisor)

wget https://github.com/BitCannaGlobal/bcna-patch/releases/download/v1.4.3/bcna_linux_amd64.tar.gz
rm  -rf ./bcna_linux_amd64.tar.gz  # delete old versions, check also bcnad in this folder
tar zxvf bcna_linux_amd64.tar.gz
./bcnad version
 >> result should be `1.4.3`

For Cosmovisor:

cp ~/.bcna/cosmovisor/current/bin/bcnad ~/.bcna/cosmovisor/current/bin/bcna_downgrade #for fast downgrade 
mv ./bcnad  ~/.bcna/cosmovisor/current/bin/
sudo service cosmovisor restart
sudo journalctl -fu cosmovisor #check the logs
