  A consensus mechanism used to secure blockchain networks. In proof of work,
  [[Node|Nodes]] compete to solve complex mathematical problems, with the first
  to solve the problem getting to add a new block to the blockchain and receive
  a reward. This requires significant computational power and energy
  consumption.
