Created as an alternative to PoW Stake means "betting"
This mechanism is called "Proof of Stake (PoS)". While PoW is supported by real-world hardware and energy consumption, the basis for the effectiveness of PoS is the perceived value of the cryptocurrency (in this case, Ethereum's Ether), which is a trade-off in game theory.

Several well-known blockchains, such as EOS and Cardano, use various elements of PoS. "The implicit assumption of Ethereum to transition to PoS in the future played a big role in advancing a different perspective from PoW. New developers and companies building their own blockchains began to immediately exclude PoW from their initial design proposals," says Laucke.
