Under the Proof-of-Work algorithm, the user is required to be constantly online and use their computing equipment to the maximum extent. The device used for mining, whether it is a GPU, ASIC, FPGA, connects to the project blockchain, accepts and validates all transactions 24/7. Under the Proof-of-Stake algorithm, the validators are responsible for network security. They are network members who pledge their tokens in a smart contract and verify the generated blocks, earning on the resulting commissions.
