Polkadot slot auction
Polkadot is composed of a relay chain and many parachains. A slot will be required for the connection between the relay chain and a parachain. With this connection, a parachain can share security with the Polkadot main chain and interact with other parachains. However, there will be a finite number of parachain slots. To ensure fairness in allocating parachain slots, we decided to use auctions. Anyone can participate. This process is called "slot auction".
