What is public chain development? What are the public chain development projects?

What is public chain : The public chain is also called “ Public chain ”, Public chain means that anyone in the world can read and send transactions , And the transaction can be effectively confirmed , Blockchains that can also participate in consistent processes . According to the centralization of the blockchain network , There are three types of blockchains in different usage scenarios : 1. A blockchain that is open to the whole network and has no user authorization mechanism is called a public chain . 2. Authorized nodes are allowed to join the network , You can view information according to your permissions , Blockchain is often used between organizations , It is called alliance chain or industrial chain ; 3. All nodes in the network are in the hands of one organization , This is the so-called private chain .

Role of public chain : 1. The public chain can protect the rights and interests of users from the influence of program developers : In the public chain , Program developers have no right to interfere with users , Therefore, the public chain can safeguard the rights and interests of users using this program . Besides , Highly decentralized distributed data storage is also one of the biggest features of the public chain , The disclosure of trading data is transparent , The advantage that data cannot be tampered with , Let the public chain effectively maintain the data security of users ; 2. The public chain can have network effects : An information product has inherent interconnection requirements , Because people produce and use them in order to better collect and exchange information . With the expansion of network scale , Users can get more value from it , Their needs can be met more . The chain of CO ownership is open , So it has the opportunity to be used by many external users , There is a certain network effect ; 3. The public chain can be used to practice business scenarios : Except for financial use , Any trust in 、 Security 、 Use scenarios with high durability requirements , Such as property registration 、 vote 、 Deal with 、 The Internet of things etc. ., Will be affected by the public chain on a large scale . What are the public chain projects :( In no particular order ) 1.QTUM Quantum chain —— Blockchain for commercial use Quantum chain combines the advantages of bitcoin ecology , Through the account general layer, it is perfectly compatible with all kinds of virtual machines including Ethereum . At the same time, the permission consistency mechanism is adopted (PoS), It provides infinite possibilities for commercial use and distributed mobile use . However ,Pos There are inherent problems with the mechanism . No specialization , Interested participants do not necessarily want to participate in bookkeeping ; Simply present forks , Need to wait for multiple confirmations ; There is no permanent end , A checkpoint mechanism is required to compensate for closure . 2.ONT noumenon —— The world's first fundamental channel to propose a distributed chain network system Ontology network is the first fundamental channel in the world to propose a distributed chain network system . In addition to the distributed ledger structure of the ontology network itself , Capable of supporting the completion of blockchain systems in different forms , It can also pass through various protocols of ontology network , From different business areas 、 Different chains in different regions cooperate , It forms a cross chain of various heterogeneous blockchains and traditional information systems . therefore , The ontology network proposes a matrix three-dimensional grid structure —— Super blend chain network structure . 3.ETP Metasphere-Metasphere Committed to revolutionizing the way financial services and buying and selling Yuan International is a lax public blockchain project . The skill structure of metasphere ecology includes intellectual property 、 Digital identity (avatar) And value intermediaries (oracle). The project will support the community to develop an intelligence based blockchain . The yuan project was developed and maintained by Wei you's team in the early stage . When the project reaches a certain maturity , The code will be released open source in github On , Wei you's team will be in Meta- Develop on the blockchain baas channel , Provide skills and business support services for enterprise users . 4.ADA—— The first reliable proof of interest algorithm ADA, Chinese call ADA The coin , yes Cardano Item intention product . Cardano It is the first game channel in the world that can prove fairness and security . It features a democratic channel that is completely independent of operator distribution . Use blockchain to create the first completely transparent and non cheating distributed game channel in the world . If you want to play the game of Cardano , You must have ADAS . Win through competition Aida The coin , But because it is not aimed at the operating company , But for other users , Winning or losing has no direct interest relationship with the operator . As for the opponent , Using a high-performance pairing system , Be able to match quickly according to the required conditions , Connect securely with your opponent . If you need , You can choose any gambling company . Cardano Adopt independent SDK( Software development kit ) System , Let individual skilled personnel participate in game development and supply , A game competition occurs , Improve game quality . 5.by Tom- Special public chain channel for property category Its most important function is to connect the atomic international and the bit international , Promote the exchange and circulation of property between the two countries . say concretely , Bit property ( Native digital currency 、 Digital property ) And atomic property ( warrant 、 power 、 dividend 、 bond 、 Intelligence information 、 Guessing information, etc .) Be able to register in a more complex way according to the contract 、 communication 、 Gambling and interaction . 6.Adture The initial chain of —— The next generation of public chains starting from digital advertising TrueChain It is a public chain specially designed for high-performance occupation , It is convenient for all professions to use and publish smart contracts efficiently . It is based on PBFT The underlying common chain , Completed without promise PBFT The consistency of , Issue for contract 、 Monitoring and lifecycle management provide efficient tools . The preliminary planning principle of the chain is to consider the use of blockchain and smart contract in the digital advertising profession , The second stage extends to other professions . In the planning of blockchain , The initial chain takes the planning of professional public chain as the policy , Coordinate the characteristics of digital advertising professional participants and future multi career concurrence , Carry out bilevel planning . At the beginning of the chain, the advertising profession is provided with basic facilities that are not constantly centralized , At the same time, it provides the first public chain for the blockchain profession to use , Breaking performance 、 Buying and selling speed 、 Career fragmentation caused by usability and other issues . 7.NEO Ant—— An intelligent and economical distributed network NEO The consistent mechanism of is DBFT, The full name is entrusted Byzantine fault tolerance .DBFT citing N A consistent system composed of consistent nodes provides fault tolerance . This fault tolerance can include both security and availability , Able to resist common and Byzantine faults , Suitable for any network environment . stay NEO Of DBFT Under the consistent mechanism , Every time 20 Seconds or so to generate a block, The service throughput test can reach 1000tps about , Reflect excellence in the public chain . After proper optimization , There should be a time to arrive 10000TPS, It can support large-scale commercial use . 8.EOS—— Decentralization uses the most powerful infrastructure EOS Through consistent algorithm (DPOS) Handled scalability issues .DPOS Every time 3 Seconds to generate a block , And only one authorized producer generates a block at any point in time . such ,EOS It can host many users at the same time 、 Speed ( only 3S) And buying and selling costs . but DPOS The possible drawback of the mechanism is : The extraordinary general meeting system will always lead to users who have many tokens , Most of the rewards were taken away by them , Which leads to “ The gap between rich and poor ” The vicious circle of , Finally, it becomes a centralized network monopolized by giants . 9.TRX Wave field —— Committed to building infrastructure for decentralized Internet Of TRON The protocol is one of the world's largest operating system protocols based on the decentralization of blockchain , Provide high throughput for decentralized use running on the Protocol 、 High scalability and reliability .
