## Recommended user journey

Complete these steps in order to go from first-time participant to active validator:

<Steps>
  <Step title="Purchase a node license">
    Visit the [Node Sale Platform](/web-apps/node-sale/overview) to buy a Core, Prime, or Sovereign license NFT on Arbitrum. Your license is an ERC-721 token that grants you the right to participate in the Autheo network.
  </Step>

  <Step title="Bridge your license to Autheo Chain">
    Use the [Autheo Bridge](/web-apps/bridge/overview) to transfer your NFT from Arbitrum to your Autheo Chain EVM address. This automatically creates a `LicenseRecord` on-chain.
  </Step>

  <Step title="Deploy and activate your node">
    Open the [Validator Portal](/web-apps/validator-portal/overview) to deploy a Sovereign validator node, bind your license, stake THEO, and begin earning rewards.
  </Step>
</Steps>

<Note>
  Prime and Core license holders can skip Step 3 and instead delegate their THEO to an existing validator via the Validator Portal to earn rewards without running their own node.
