“ The belief in creating a parallel chain model is ,Web3 The future of will involve many different types of blockchain collaboration . Just as the current version of the Internet meets different needs , Blockchain needs to be able to provide various services . Parallel chains solve this problem .” —— Polkadot founder Gavin Wood

Key points

  • Polkadot Before 11 A parallel chain has been online

  • front 11 The parallel chain is locked in for a two-year lease 1.26 Billion DOT( Of the total supply 11%; value 21 Billion dollars )

  • Each parallel chain brings unique functions and use cases to the ecosystem

  • The next major technical task is to build a cross consensus message format (XCM)

brief introduction : Parallel chain is online

2021 year 12 month 17 Japan , Five years after the idea ,Polkadot Successfully completed multi-stage release , And released the first parallel chain . Now the parallel chain has been online , End users can finally Polkadot Trading on .

What is parallel chain ?

Parallel chains are used Polkadot Blockchain development framework Substrate Developed application specific 、 Highly customized second 1 layer . It has its own economy 、 Tokens, 、 Governance and user mechanisms , Like the traditional third 1 layer . However , With the traditional third 1 Different layers , Parallel chains are not isolated . contrary , It's connected to Polkadot Another major technical component of the relay chain .

What is a relay chain ?

The trunk link is Polkadot At the heart of . It contains all verifiers and is responsible for protecting 、 Managing and connecting parallel chains 0 Layer foundation chain . In addition to relay chain governance , Parallel chains also have sovereign governance , The following analogy will further explain . The trunk chain can support about 100 To 250 A parallel chain . The upper limit of parallel chain is mainly composed of and extension Polkadot Cross chain messaging (XCMP) Related cost drivers , And abide by the best 10:1 Verifier to parallel chain ratio to maintain decentralization and performance quality .

Analogy to the United States : The relay chain is the federal government , Parallel chains are States . The federal government protects 、 Manage and unite the States . If there is a dispute , The status of the federal government is higher than that of the state government .

Polkadot Tokens, (DOT) What's the role ?

 Polkadot Native token of DOT Is a practical and governance token , For participation in governance 、 Pay for the transaction 、 Obtain security and parallel chain slots through pledge . By 2022 year 3 month ,DOT Is the most commonly held asset in crypto funds .

Learn more about Polkadot, Please refer to our previous report Polkadot Primer One and Polkadot Primer 2:

In addition to venture capital ,Polkadot Unique architecture and Substrate Combined with flexibility , Attracted the second largest developer community . Now the parallel chain has been online and has obtained a lot of venture capital funds , The fruits of developers' labor can be used by the public . In this report , We'll go into that Polkadot Before 11 Parallel chains .

Ecosystem Overview - front 11 Parallel chains

As mentioned above , The relay chain can support estimation 100 To 250 A parallel chain . In order for the parallel chain to get the help provided by the relay chain , You must lock the maximum number of DOT To win the candle parallel chain slot auction .

Potential parallel chains are usually raised through their communities DOT, In exchange for their native tokens . Random time in candle auction , Have the most bindings DOT The parallel chain wins the slot . At the end of the lease term , Binding of credit DOT Will be returned to ( And they keep parallel chain tokens ).

after 11 The auction , Has pledged 1.26 Billion DOT( Of the total supply 11%; value 21 Billion dollars ). The first Winners ( The auction 1-5) On 2021 year 12 month 17 Join in Polkadot. The second batch of winners ( The auction 6-11) On 2022 year 3 month 11 Join in Polkadot. Each winner brings a unique Polkadot Ecosystem functions and use cases .
