Becoming a Validator

Overview:

A Validator is an independent individual who stakes their identity and is entrusted to maintain a node on the network that validates transactions and commits new blocks to the blockchain. Validators receive a reward in POA token for provisioning blocks.

Responsibilities:

A Validator has technical and social responsibilities, both of which are important for the health, performance and security of the network.

Technical Responsibilities:

  • Ensure node is secure by practicing safe key management
  • Maintain node requisite software version
  • Monitor node to ensure its availability and participation in consensus
  • Monitor network in general and communicate with other Validators, network entities if problems arise.

Social Responsibilities:

  • Participate in on-chain Governance of the network. A collection of DApps allow Validators to propose and vote on ballots to manage the network. The Ballot types include:
    • Adding new Validators
    • Removing Validators, i.e. for compromising security of network, malicious behavior, non-participation in Governance
    • Updating/swapping of one of more Validator keys
    • Changing the Approve Ballot Threshold
    • Changing Consensus Proxy Contract
  • Participate in POA Network Community Forum
