Staking

Description

Blockchain for Good:

"Staking involves a user immobilizing and locking tokens in a smart contract. The protocol randomly assigns one of the participants the right to validate a block of transactions and receive a token reward.

The "proof-of-stake" mechanism encourages users to lock up their tokens, as the probability of being chosen to validate a block of transactions is proportional to the number of tokens locked. The more tokens a user has locked, the higher the probability of being chosen to validate the transaction.

If a user attempts to write false transactions into a block, they lose their locked tokens and are banned from the network."
