Proof of Work (PoW)
Securing a chain by requiring real computation.
Proof of work secures a blockchain by making block production require real, costly computation. The network trusts the history with the most work behind it, so rewriting the past is prohibitively expensive.
This is what miners do: spend computing power to earn the right to add blocks and collect the reward. Pearl is a proof-of-work coin.
