This fact drastically reduces the energy consumption needed. Proof of Stake also improves decentralization, security, and scalability.

Proof of Work (commonly abbreviated to PoW) is a mechanism for preventing double-spends. Most major cryptocurrencies use this as their consensus algorithm. That’s just what we call a method for securing the cryptocurrency’s ledger.
