Answer: Proof-of-Work (PoW) and Proof-of-Stake (PoS) are consensus mechanisms used to secure blockchain networks.

Proof-of-Work (PoW): In PoW, miners compete to solve complex mathematical puzzles. The first one to solve the puzzle gets the right to add a new block to the blockchain and is rewarded with cryptocurrency. This process requires significant computational power and energy. Examples include Bitcoin and Ethereum (before its transition to PoS).
Proof-of-Stake (PoS): In PoS, validators are chosen to create new blocks based on the number of coins they hold and are willing to "stake" as collateral. The selection process may also consider the age of the stake and other factors. PoS i…

The selection process may also consider the age of the stake and other factors. PoS is more energy-efficient than PoW since it doesn't require extensive computational work. Examples include Ethereum (post-transition), Cardano, and Polkadot.
