Validator Registration

Note: if your client is not synced, it might take some time to get your transaction posted - the validator only submits the transaction as soon as your node is synced with the network.

You must have an unlocked account with enough mining tokens to cover the initial deposit required to participate in the consensus. If you wish to join the consensus let us know in our Telegram or Gitter channel, and we will mint enough mUSD tokens to your account.
