According to Foresight News, Ethereum L2 Starknet has published a document outlining its roadmap for moving to the PoS mechanism. Currently, the first phase of staking has been carried out on Starknet Sepolia, where a permissionless staking protocol and a delegated staking mechanism are introduced. Validators are expected to run a full node to prepare for the next phase. In the second phase, validators will begin to prove blocks, that is, sign blocks at random times. In the third phase, validators will verify and vote on blocks sorted by the sorter, and the consensus will send proofs to L1. In the fourth phase, validators will be solely responsible for maintaining and protecting the network by generating and proving blocks.
