Proof of work sets peers in the network against each other in a game to see who can correctly solve a computationally intensive puzzle the quickest. The winning peer obtains the right to update the state of the network (i.e. write the next transaction in the ledger) and broadcast that update for the rest of the peers to validate for correctness. Once the work is proved to be correct, the peer receives (i.e. mines) a token from the protocol as a reward.",en,GLOSSETA-PROD,general

The Beacon Chain introduces a Proof-of-Stake consensus mechanism to the network which allows ETH holders to stake their ETH and become validators in ETH2.0.

Validators are rewarded with the native token of the chain upon the submission of successful blocks; however, if a validator is deemed a bad actor, they are punished by losing their deposited token.",en,GLOSSETA-PROD,general
