Upgrade your node
This document is the FirmaChain binary upgrade guide.
When the chain reaches a pre-designated block height the chain comes to a halt by displaying the message below.
ERR UPGRADE "<version>" NEEDED at height: "<height>"
panic: UPGRADE "<version>" NEEDED at height: "<height>"
Please manually delete the chain that came to a halt with the error message.
# using binary
kill -9 firmachaind
# or using system service
sudo systemctl stop firmachain
Build the binary after changing the branch that corresponds to the appropriate version.
git checkout <version>
Finally, you can start the syncing process
