Among them, the PoA version of the mainnet is expected to be released between April 22 and 27. At this stage, the NEAR protocol will be run in the Proof of Authorization (PoA) mode, and the initial node settings will be operated by the NEAR Foundation. Token distribution, most token transfers are restricted at this stage, and only the NEAR Foundation can transfer tokens.

In the second stage, the restricted window period of the mainnet stage is from June to August. In this stage, most accounts are prohibited from transferring money. The locked contract cannot be directly staking, but can only be delegated. Therefore, the initial validator setting needs to be set by the whitelist. Validators are delegated without any inflation and rewards in this phase. In the first and second phases, developers need to be authorized by the NEAR Foundation to deploy applications. The last stage is the mainnet stage governed by the community. The network will not require permission and there will be no restrictions. Validators and delegators are responsible for the continued operation of the network and the decision to upgrade.
