* Ursula Node Operator Notice *
-------------------------------

By agreeing to stake 15000 NU: 

- Staked tokens will be locked, and unavailable for transactions for the stake duration.

- You are obligated to maintain a networked and available Ursula node with the 
  ETH address 0xF59CFb62c66be1dBe0B7b66f2108cb3bFE91667F for the duration 
  of the stake(s) (30 periods)

- Agree to allow NuCypher network users to carry out uninterrupted re-encryption
  work orders at-will without interference. 

Failure to keep your node online, or violation of re-encryption work orders
will result in the loss of staked tokens as described in the NuCypher slashing protocol.

Keeping your Ursula node online during the staking period and successfully
performing accurate re-encryption work orders will result in rewards 
paid out in ETH retro-actively, on-demand.

Accept node operator obligation? [y/N]: y
Publish staged stake to the blockchain? [y/N]: y
