Proof of Stake
What is Proof of Stake?
A way for a blockchain to agree on new blocks, where validators lock up coins as collateral.
Understanding Proof of Stake
In proof of stake, validators are chosen to propose and confirm blocks based on the coins they have staked. Dishonest behavior can be punished by losing part of the stake.
It uses far less energy than proof of work, where miners compete using computing power, as in Bitcoin.
