Proof of Stake
Securing a ledger by putting capital, not electricity, at risk.
Validators lock assets as collateral and are chosen to propose blocks in proportion to that stake. Misbehaviour can be punished by destroying part of the deposit. It removes the energy cost of proof of work and replaces it with a different question: how concentrated the stake becomes.
