Polkadot Parachain Auction and Crowdloans Explained
Everything you need to know about the upcoming parachain auctions on Polkadot 🔴
- Projects that want to become a parachain on Polkadot or Kusama need to win a parachain auction
- Fearless Wallet supports all parachain auctions on Polkadot and Kusama by default (some crowdloans with custom features will be supported on a case by case basis)
- On Polkadot, the parachain leasing period is a max. of 96 weeks, while on Kusama, it is max. 48 weeks
The Polkadot parachain slot auctions start on Nov 11. But, what are Parachain slot auctions and crowdloans on Polkadot (or Kusama)? And how can I participate in crowdloans?
Projects that want to become a parachain on Polkadot (or Kusama), need to win a parachain auction from this point on they will be referred to as Crowdloan Campaigns.
Here is a brief overview of how the process works, and how you can participate in crowdloans with Fearless Wallet in an easy way.
Note: Fearless Wallet supports all Crowdloan Campaigns on the Polkadot and Kusama networks by default*
*If the Crowdloan Campaign that you wish to support has a custom flow, please check compatibility directly with the project first
Blockchains: Parachains and Relay Chains
Background: Polkadot (DOT) and Kusama (KSM) are so-called “Relay Chains” which are designed to host blockchains called “Parachains”.
- Relay Chain: The Relay Chain is the central chain where transactions are finalized. (Polkadot and Kusama)
- Parachains: Blockchains that are pegged to the relay chain
Parachains are blockchains that operate on top of the Polkadot and Kusama networks. Different Parachains can be developed to match their individual design and specifications, e.g: decentralized finance (DeFi), identity management, and gaming. This is significant, as no single blockchain is optimal for all use case scenarios.
With Fearless Wallet you can easily buy Polkadot (DOT) and Kusama (KSM) tokens with a few clicks.
How Do Polkadot Parachain Auctions Work?
A parachain auction offers an opportunity for Substrate-based (framework for building blockchains on Polkadot or Kusama) blockchains to connect to the Polkadot or Kusama relay chains. This is achieved via an open and permissionless auction while benefiting from the security of the relay chain (Polkadot and Kusama). However, Parachain slots are scarce by design in order to encourage competition and to optimize the relay chain’s resources. On Polkadot, the parachain leasing period is a max. of 96 weeks, while on Kusama, the parachain leasing period is max. 48 weeks.
So-called “candle auctions” are the auction mechanism for parachain auctions. This particular auction-style traces back to the 17th century, when the bidding was allowed until a candle burned out. The highest bid up until that point was considered the winner. Candle auctions are implemented to avoid “auction sniping”, where an entity would come in at the end of the auction and outbid all other contenders. Thus. candle auctions have the major advantage of not knowing exactly when the auction will end, and therefore, participants are more likely to place early bids that correspond to their estimated value of the auctioned item. This has led to more accurate pricing in parachain slot auctions. For more detailed information you can read the research article on candlelight auctions by the Web3 Foundation.
Crowdloans Are Used to Win a Parachain Auction
Crowdloans allow the community to provide a project with DOT or KSM to participate in a parachain auction in order to win a parachain slot. The Сrowdloan process allows the community to contribute to the project by locking their own DOT or KSM until the lease period is over. In this process, the projects that participate in parachain auctions reward DOT or KSM contributors with their native blockchain token. The contributed DOT (for Polkadot auction) or KSM (for Kusama auction) are automatically returned after the parachain leasing period is over. And if the project does not win the parachain auction, then the DOT or KSM tokens are returned in a few days. (current batch).
