Many people know about parallel chain slot auctions, but don't understand the concepts of system parallel chains, nested relay chains, transfer Bridges, and candle auctions. Although we don't need to be coinage scientists, Boca is one of the hottest topics of the year in coinage, so these concepts need to be understood.Today I'm going to try to explain these concepts in simple terms.Pokar is essentially a scalable heterogeneous multi-chain blockchain, which consists of a relay chain and some shard chains running in parallel.The purpose of a relay chain is to protect parallel chains from running smoothly and then to be shared with parallel chainssecurity, parallel chains are other chains that want to connect to Poca.The parallel chain and the relay chain need slots to connect. The relay chain could theoretically expand indefinitely, but there are only about 100 slots available for use, and not all of them are being auctioned off.At present, parallel chain is divided into public interest chain slot, parallel chain slot for auction and parallel thread.As you can see from the chart above, fewer than 100 slots were actually auctioned, so the auction of slots became very competitive.And we should pay attention to a point, the parallel chain slot competition is no ownership, there is only the right to use, a cycle is 6 months, the longest is two years. This is also to ensure the vitality of the whole ecology, also a little bit of the last out of the meaning, give you two years at most, if you do not do well in two years, then it is necessary to replace.There are three kinds of parallel chainsPublic welfareParallel chains, which are permanent, serve the entire Boca ecosystem, just as the government will allocate some funds and resources for infrastructure. Public parallel chains are used for Boca ecosystem infrastructure.For example, if transfer Bridges are parallel chains generated based on the Substrate framework, they can be easily achieved due to the same consensus mechanismAcross the chainInteractions, this is also called isomorphic cross-chain, but there are some very mature projects; For example, in Ethereum, since the consensus mechanism is different, a transfer bridge is needed as an intermediate translator to interact with Poka, and a transfer bridge is a public parallel chain.Nested relay chains, which are parallel chain slots used primarily for auctions. In fact, it is a bit like a row plug, for example, the relay chain is a row plug, the above jack is limited, now almost 100, obviously this is not ecological use.So a nested relay chain is like taking another socket, so you have 100 more jacks to use, and a nested relay chain is like a relay chain in a relay chain, allowing Poca to expand indefinitely.Parallel thread also means parallel chain, but the object used is different.The parallel chain slots obtained by the auction are for unlimited use of the project, while parallel threads are for those who do not succeed in bidding, but are in desperate need of cross-chain functionality, so they can use parallel threads, which are charged on a per-block basis, which is more expensive than parallel chain slots.It's as if the project that bids for slots has an unlimited data card and can use it for the duration of the lease, while the project that doesn't bids has to buy data to use it.And then the auction, the slot auction is a candle auction, which originated in England in the 17th century, where you light a candle at the time of the auction, and when the candle goes out, the auction ends, because you don't know when the candle is going to go out.In an online auction, the system would have to pick a random number to determine the end time, but the slot auction has been improved so that you know when the auction is going to start and when the auction is going to end, but you don't know when the auction is going to end.Taken it is not the time to the auction ended, but the traceability to determine end sometime in the past, it means that at the end of the final, then random is a block of the past, the past block is a real auction by the time, but this is after the walk is the complete process, so no one will know in advance what is the real interception time auction.Because online auctions are vulnerable to hackers who know when they start and end, the improved candle auction can avoid this.Slot auctions are a big deal in the currency community, and some of the projects that are based on auctions are crowdlending (PLO).Auction requires a large amount of KSM and DOT, and some project parties do not have so many tokens, so they will initiate PLO, that is, to allow retail investors to contribute their tokens to support the auction of the project, and retail investors can obtain the tokens issued by the project party, which is equivalent to locking up positions to obtain the coins issued by the project party.As a result, the demand for KSM and DOT has increased several times in the past few months, and will continue to move independently in the coming month.Author: V Ke, [Blockchain thinking] chief manager
