Updating a node

Update process​

The exact update procedure depends on how you previously installed your node.

The basic process goes as follows:

  • Stop your previous node, as running 2 nodes with the same keys will lead to loss of coins
  • Backup your node wallet folders (massa-node/staking_wallets and massa-client/wallets)
  • If needed, backup you custom config files (massa-node/config/config.toml and massa-client/config/config.toml)
  • Install your new node by following the documentation.
  • Restore your wallet folders to their respective location
  • If needed, restore your custom configuration

If, during the process, you missed enough block production, your rolls may be automatically sold. If that is the case, wait for the coins to get reimbursed automatically (taking ~3 hours), and buy your rolls again.

Updating the git repository (if installed from sources)​

If you installed from sources, you can either re-clone the repo, or you can update your existing repo to the latest release.

In order to update to the latest release, launch a terminal in your current repository, and then run the following commands:

git fetch
git checkout MAIN.2.5

Accepting "Massa Community Charter"​

Starting from version 2.5, when running a Node for the Massa blockchain, you have to accept the "Massa Community Charter".

The Charter is displayed the first time you run a node. Read it carefully until the end then press 'y' if you fully agree with it in order to run your node.

Alternatively, you may choose to read the Charter beforehand and run your node with the '--accept-community-charter' option if you accept the conditions. Please note that running the node with '--accept-community-charter' option implies you've read and approved the Charter.
