NodeDAO Oracle daemon

Oracle daemon for NodeDAO decentralized staking service. Collects and reports Beacon Chain states (the number of visible validators and their summarized balances) to the NodeDAO dApp contract running on Ethereum execution layer.

For oracle contracts, see: King-Hash-Org/NodeDAO-Protocol⁠

⁠Working Mechanism

• Upon the start daemon determines the reportable epoch and retrieves the list of validator keys to watch for.
• Then it Gets the NodeDAO-controlled validators from the reportable beacon state and summarizes their balances.
• Constructs the transaction containing the epochId, beaconBalance, beaconValidators and validatorRankingRoot.
• If the daemon has privateKey in config file, it signs and sends the transaction to the oracle contract.

⁠Config File

config-default.json

{
  "log": {
    "level": "info"
  },
  "network": "goerli",
  "beaconNodeAddr": "",
  "executionLayerAddr": "",
  "privateKey": ""
}

⁠Configuration details

⁠Note:

• Ensure connectivity between the ETH execution layer and the ETH consensus layer nodes for which the executionLayerAddr and beaconNodeAddr parameters are set.
• Ensure that privateKey's private key is authorized by Oracle-Dao.
