Therefore, the Kusama website will The start date of the first auction will be announced this week, along with the expected timetable for further auctions. Currently, the Kusama network expects to conduct five auctions with 7-day intervals between each auction. Further auctions may follow thereafter if no major issues are identified Auction.

The parachain slot auction has not yet started, and some representative projects are ready to go, publicly declaring that they will participate in the parachain slot auction, such as Acala, Phala, ChainX, Darwinia, Bifrost, Stafi, Litentry, Mathchain, etc.

What is a parachain slot auction?

Parachain Slots are the interface between the relay chain and the parachain. In order to share the security of the Polkadot network and conduct business interaction with other parallel chains, it must be realized through slots. The slots are divided into community beta slots and commercial slots. 20% of the slots are reserved for deployment and support by the Web3 Foundation, as a community beta parachain to promote the entire Polkadot ecosystem The remaining 80% of the slots will be used as commercial slots and will be opened through auctions.

Since the operation of parallel chains needs to consume certain network computing resources, in order to ensure network efficiency and security, the number of parallel chains in the initial stage is limited. Polkadot founder Gavin Wood said at the Polkadot China Tour event in July 2020 that the upper limit of the number of parachains will be about 100, which means that the upper limit of the number of slots running at the same time is also about 100.

In order to ensure fair distribution, Polkadot has designed an auction method that allows project parties to obtain the right to use slots through bidding. The right to use means that the slot is only rented and not sold, and the project party needs to bid for the right to use by locking a certain amount of time and a certain amount of DOT. After the lease period ends, the locked DOT can be unlocked and returned. (Note: DOT that has participated in pledge mining cannot be used to participate in auction lock at the same time)

How does the slot auction work and how to participate?

In order to reduce auction sniping, Polkadot parachain slots will use "candle auctions", and some improvements have been made on traditional candle auctions, and a retroactive closing mechanism has been used.

The way the candle auction works means that everyone knows the status of the auction, but not when the auction will end, which helps ensure that bidders are more willing to bid early. There are two stages in the Polkadot parachain slot auction process: security period and random period. DOT can be freely pledged in both stages, and the auction will stop suddenly at an unpredictable time point in the random period, and the bids before this time point will be won by the highest bidder. Therefore, bidders need to bid early and stake as much chips as possible before the second stage.

The auction of parachain slots takes place every six months, and only one slot is released each time. The lease period of the slot is based on 6 months, divided into 6 months, 12 months, 18 months, and 24 months. Only the items participating in the auction can bid freely, bidding for a single or adjacent multiple lease periods , the highest price wins. The successful bidder needs to lock (stake) its DOT within the corresponding period, and the deposit will be refunded at the end of the parachain lease period.

If the project party has insufficient funds, it can also become a parachain through PLO (Parachain Lease Offerings, Gavin called it crowdloan, crowd loan) and apply for funding from the Web3 Foundation. For example, through a series of incentives to attract investors to lock DOT to themselves, in turn, investors can also lock their own DOT in the auction module to support their favorite projects. If it fails to be auctioned to become a parachain, it can also be connected to the relay chain through a parallel thread.
