The final phase of Polkadot’s mainnet launch has begun.

Polkadot has entered the final phase of its mainnet rollout, which includes deploying parachains on the Kusama experimental network, according to Gavin Wood, the project’s founder.

And proposition 110 passed! In two hours, the deployment will be completed and if all goes well we’ll start seeing the first blocks on a live @kusamanetwork parachain. Here’s an article with more details: https://t.co/xTbFtx2GPI pic.twitter.com/3bLOjvi9KN

Parity Technologies develops Polkadot. According to Wood, the company has released a client version 0.9 that includes the functionality required to launch parachains.

The updated software is already running on most Kusama nodes. The final algorithm for conducting parachain-slot auctions and the crowdloan logic have been implemented. They allow investors to pool their assets to back a particular blockchain.

Parachain launches on Polkadot will take place after a full external audit of the update is completed. Wood noted that the audit has already begun and will be completed “in the near future”.

Kusama must also demonstrate the viability of the new logic. For this, the network will host “at least one successful auction involving crowdloans and deploying a functional parachain”.

Polkadot’s parachains launch is expected to begin once two things have happened:
1. A full external audit is completed.
2. @kusamanetwork executes at least one successful auction involving crowdloans and hosting at least one functional parachain.

On 17 May 2021, Kusama approved a parachain called Shell, which produces blocks but has no other functions. When it proves its viability, auctions will be launched in the network—and the first will be announced seven days before the start.

Over the next two months, developers will test the system’s resilience. For now, the actual transaction throughput is artificially limited to 25% of its potential. Performance will gradually be increased.

In April 2021, Tether announced the launch of the USDT stablecoin on the Polkadot and Kusama networks.
