Update your validator node

:::tip Rewards
Upon completing this challenge, you will be rewarded 50 Desmos Tokens.

Additionally, you will also earn more tokens the longer you keep the node running. To know more about this please reference the Validators program.

Please note that we exported the morpheus-3000 state at height 845,600.

However, to allow all validators to have a chance of earning all the tokens by completing this challenge, we will start counting the precommits from the first block generated after 1st May 2020 00:00 UTC.

When a new version of Desmos is released, all validators need to update their node so that it can keep running properly. Following you will find the guide on how you can do this making sure everything is ready for when the new chain starts.

1. Stop the running service:

   sudo systemctl stop desmosd

2. Update the Desmos binaries:

   cd ~/desmos
   git fetch -a 
   git checkout tags/v0.4.0
   make install

3. Delete the current genesis.json file and download the new one:

   rm ~/.desmosd/config/genesis.json
   curl https://raw.githubusercontent.com/desmos-labs/morpheus/master/genesis.json > ~/.desmosd/config/genesis.json

4. Verify the validity of the generated genesis.json file by running the following commands:

   jq -S -c -M '' ~/.desmosd/config/genesis.json | shasum -a 256

   The output should be

   dc6bcadf360f037450066bfad89bc54c467810240ac93a317bf5f26cab80079f  -
   

5. Reset your node to make sure everything is ready:

   desmosd unsafe-reset-all

6. Open up the config.toml file:

   nano $HOME/.desmosd/config/config.toml

7. Locate the persistent_peers = text at line 164 and change the whole line to be:

   persistent_peers = "[email protected]:26656,[email protected]:26656"
   

8. Start your new node:

   sudo systemctl start desmosd

Now you should be able to see your node properly syncing with the other ones by executing:

journalctl -n100 -f -u desmosd.service
