Multichain setup

Last updated: 2024-02-15

The guide below is for running a node on both NeuroWebAI and Gnosis chain.

OriginTrail DKG V6 nodes are chain agnostic. You can set up one node on a server and use the same node on different blockchains. Each chain requires 50k TRAC to activate the node on that chain and to start submitting commits (winning assets).

Example: To run a node that submits commits on both NeuroWebAI and Gnosis, you will require:

• 50k TRAC on NeuroWebAI + 2 NEURO for gas

• 50k TRAC on Gnosis + GNO for gas

The delegated stake can come from you or someone else.

The DKG V6 on Gnosis is expected to go live in mid February 2024 alongside delegated staking. Delegated staking on NeuroWebAI will come at a later time.

Step 1 - Preparations

Begin by obtaining xDAI for operations on Gnosis chain through their faucet.

If you require more xDAI, you can use Jumper to swap any assets to xDAI on Gnosis.

Since Gnosis is EVM compatible, you can use your Ethereum wallet on MetaMask or Ledger for all operations on the chain.

If you want to delegate to your own node, bridge your ERC-20 TRAC from Ethereum to Gnosis by using the Omnibridge.

A node can be fully operational with delegated stake only as long as the total stake amount is 50k TRAC or above.

Now, you need an Archival RPC Endpoint to communicate with the Gnosis chain. Note that not all providers provide archival endpoints. You will need to sign up through their links and get an Archival RPC Endpoint.

For a free Archival RPC Endpoint, try out BlockPi or OnFinality.

Step 2 - Configurations

Head to your node config with the alias

otnode-config

or manually

nano ~/ot-node/.origintrail_noderc

Then, add the following to your config file

"gnosis:100": {
  "enabled": true,
  "config": {
    "rpcEndpoints": [
      "https://<desired_rpc_endpoint>"
      ],
    "gasPriceOracleLink": "https://gnosis.blockscout.com/api/v1/gas-price-oracle",
    "sharesTokenSymbol": "shares_token_symbol",
    "sharesTokenName": "shares_token_name",
    "operatorFee": "5",
    "operationalWallets": [
      {
        "evmAddress": "0x0bf...",
        "privateKey": "0x1e3..."
      }
    ],
    "evmManagementWalletPublicKey": "0xd09..."
   }
}

The end result should look like this. Double check for syntax errors!

          "enabled": true,
          "package": "./triple-store/implementation/ot-blazegraph/ot-blazegraph.js",
          "config": {
            "repositories": {
              "privateCurrent": {
                "url": "http://localhost:9999",
                "name": "private-current",
                "username": "admin",
                "password": ""
              },

                "name": "private-history",
                "username": "admin",
                "password": ""
              },
              "publicCurrent": {
                "url": "http://localhost:9999",
                "name": "public-current",

                "password": ""

              "publicHistory": {

                "password": ""
              }
            }
          }
        }
      }
    }
  }
}

Before applying the config changes by restarting the node, make sure you added your operator fee. Once the config is applied, you will not be able to change operator fee for 28 days.

ctrl+x and ctrl+s to save and restart your node

otnode-restart && otnode-logs

If you added everything successfully, your node will show:

blockchain module initialized with implementation: gnosis:100

Step 3 - Set node ask

The default ask is set to 0.01 in the script below. Please change it to your desired ask price.

npm -C /root/ot-node/current run set-ask -- --rpcEndpoint=https://astrosat-parachain-rpc.origin-trail.network/ --ask=0.01 --privateKey=$(jq -r '.modules.blockchain.implementation.otp.config.evmOperationalWalletPrivateKey' /root/ot-node/.origintrail_noderc) --hubContractAddress=0x5fA7916c48Fe6D5F1738d12Ad234b78c90B4cAdA

Step 4 - Add stake

Visit Houston and connect your admin wallet. Head to Service Tokenomics and follow the on screen instructions to set up node operator fee, node ask and node stake!

You can then visit the staking dashboard to find your node.

Done!
