According to TechFlow, on October 16, Starknet published a statement on the X platform stating that although the first phase of staking has been launched on Starknet Sepolia, it must be emphasized that this is just the beginning of a broader plan to transform Starknet into a fully decentralized PoS network. The vision for this transformation is as follows:
Phase 1: Introducing a permissionless staking protocol and staking delegation, validators are expected to run a full node in preparation for the next phase.
Phase 2: Validators will start attesting blocks, i.e. signing blocks when their turn is randomly chosen.
Phase 3: Validators will validate and vote on blocks ordered by the collator, and consensus will be proven to L1.
Phase 4: Validators will be solely responsible for maintaining and securing the network by generating, attesting, and proving blocks.
This phased approach allows Starknet to roll out staking carefully and adjust over time to meet the evolving needs of the community. Additionally, the four phases above are not a rigid or static plan and may change based on what is observed during this process.
