The Polkadot network will have a phased launch plan, with each phase being a more decentralized milestone.

Gavin Wood's latest speech: Polkadot mainnet launch process

The online process starts with the "alternative chain", which will be released by the Web3 Foundation in the form of a proposal for the Polkadot relay chain. The alternative chain will generate a genesis block, which means that the chain is officially launched.

This new chain will run in the form of PoA (Proof of Authority), and the Web3 Foundation will fully control this chain.

Gavin's own handwriting: Polkadot launches the second phase of NPoS network

At the beginning, the governance function of the blockchain will be controlled by the Sudo module. The Sudo module is a very special functional module that allows a role, the Web3 Foundation, to completely control and rewrite all operations of the blockchain, including the chain logic, reprogrammed.

It includes four modules: The first is the referendum module, which allows the use of a token-weighted voting system, which means that token holders can control the fate of the Polkadot network to a certain extent.

The second is the Polkadot network council module, the third is the technical committee, and the fourth part is the department responsible for governance—the financial library.

The final operational logic upgrade initiated by the Web3 Foundation will remove the Sudo module and in the process remove its own omnipotent status, since it can delete chains just as it can generate new alternative chains.
