Turning Ithacanet into a permanent testnet: Ghostnet

Research and Development
9

We will update Ithacanet to Jakarta protocol at block 765,952. The first Jakarta cycle will be cycle 187. This should happen on June 28th a few hours before the mainnet upgrades to Jakarta as well.

In order to remain on the network, every ithacanet baker must do the following:

  1. upgrade to octez 13.0
  2. turn on the jakarta baker alongside the ithaca baker
  3. configure the jakarta user-activated upgrade

Configuring the user activated upgrade requires a change to the tezos json configuration.

The tezos json configuration file is typically at ~/.tezos-node/config.json but may be in a different location.

To add the jakarta user-activated upgrade, issue the following command:

tezos-node config update --network https://teztnets.xyz/ithacanet

If your config file is not at the default location, add --config-file /path/to/config.json to the command above.

You should now see the following in your config.json:

  "network": {
    "chain_name": "TEZOS_ITHACANET_2022-01-25T15:00:00Z",
    "genesis": {

          "ithacanet.stakenow.de:9733", "ithacanet.visualtez.com" ],

      }
    }
  }

A restart of the node is required for the configuration change to take effect.
