What are the conditions for a high-quality public chain?

What people who pay attention to blockchain technology have to know is the underlying public chain project of blockchain , Whether it's investment or money speculation , We must find high-quality coins with development potential . So what is the bottom common chain , Which of the bottom public chains has done the best ？

Blockchain project development

The underlying public chain is actually the infrastructure project of the underlying protocol layer in the blockchain project , That is, the basic common chain . Like Ethereum ,EOS, Little ant stocks , Quantum chains, etc , Are well-known public chains , Of course, some of them are very strong , But the public chain with relatively less popularity , such as AOA Aurora chain .

The underlying public chain is actually a basic platform for better development of applications of other blockchain projects . If there is no underlying public chain , To develop a blockchain project is like making a project on a mobile phone without an operating system APP It's just as difficult , Because everything starts at the bottom .

The first underlying public chain project born in the blockchain is the well-known Ethereum , It is because of the low-level public chain project , Ethereum is in 2017 It can become the currency with the fastest growth rate in the currency circle , Achieve blockchain 2.0 Legends and myths . The role of the underlying public chain is like the Android or... Of the smart phones we use today iOS System , If you want to develop a blockchain project, you can directly complete it based on the underlying public chain , Greatly reduce the difficulty and cost of development .

So when we invest in the public chain , If you have a unique vision, select a similar one iOS The system is generally stable and smooth , Then wealth and freedom are not far away . But from the current public chain , Such as Ethereum , Its existing TPS Too little , Trade congestion , and EOS Over centralization , None of them seems to be the best choice , Is there any other public chain that can do better ？ Xiaobian checked a lot of public chain information , It is found that a public chain can almost cover the advantages of other well-known public chains , That's what I mentioned earlier AOA Aurora chain .

AOA Aurora chain focuses on the ideal ​ On ​ The combination of reality , Efficiency and practicality coexist ,AOA The main chain can be deeply connected to various applications , Accelerate the implementation of blockchain applications . And it focuses on making the most perfect contract , Contract is the link between blockchain and other industries , No contract , Can not be combined ; Blockchain's support for contracts , To some extent, it reflects the depth of the integration of blockchain with other industries , Only the bottom layer is rich 、 High degree of freedom 、 The contract with perfect code can meet the needs of all walks of life .

as everyone knows , The current design of public chain , It has the following characteristics ：

1. All master nodes should keep a complete account book , To ensure safety ;

2. Every time the ledger is updated , All primary nodes should keep fast synchronization ;

3. To ensure decentralization , There should be as many primary nodes as possible .

Because of the different running speeds of each master node 、 network bandwidth 、 Motivation, etc , This leads to the realization of the above three points at the same time , The blockchain proposed by the long clip will appear “ Impossible Triangle ”.

The blockchain investment market was booming last year , Trading volume soared ,BTC and ETH The performance problem of is highlighted , People finally began to face up to this triangle , Especially scalability （ High performance ） This corner , In an instant , Various PoX Consensus mechanisms have mushroomed . However , except DPoS With “ Weak centralization in exchange for performance ” Has been generally recognized for the time being , most PoX Are of little value .

2018 year , Many projects give up following in the chain “ Impossible Triangle ” hard ​ Bar ​ Ideas , Second best , Conduct “ Curve of national salvation ”. So ,“Layer 2 Offline expansion and fragmentation ” Become the main direction of public chain expansion this year ,ETH Of Plasma Capacity expansion 、Zilliqa Slice technology of 、Liquidity Network And Celer Network The state channel of has become a hot technology this year .

However , Is the problem really solved ？

Sharding and offline capacity expansion can indeed improve TPS, Improve scalability , However, there are two hard injuries ：

A hard wound ： The implementation of sharding technology is difficult

Fragmentation naturally conflicts with the core spirit of blockchain . Blockchain pursues “ Network wide consensus ”, The data of each node is exactly the same , So as to achieve high security without tampering .

And now , Each node processes only a portion of the information , And completely unaware of the information of other nodes , This is to be achieved “ Network wide consensus ”, The difficulty increases .

This is why Ethereum has been working in pieces for so long , The main reason why there is no obvious breakthrough in the progress . The current leader in segmentation Zilliqa, It just realizes a simple transaction segmentation . As for contract and status segmentation , It needs to cooperate with the design of the corresponding virtual machine and contract language . therefore , Naturally, it's even harder . at present , Maybe only the aurora chain can solve this problem .

Hard injury II ： Offline capacity expansion technology is still limited by performance

Layer 2 It is to move many transactions on the chain down the chain , Because there is no need to “ Network wide consensus ”, So just put the final result back on the chain for confirmation , Speed has been improved .

There are two problems with this approach ： One is still subject to the performance of the chain itself , After all, the final result should be returned to the chain for confirmation ; Second, the application scenarios are limited , For example, two people play a game of Gobang , This thing is very suitable for Layer 2, But if there are many people ​ Of ​ One off non recurring transactions , The capacity expansion under the chain can't help .

therefore , If there is “ The next stop is the public chain ”, Or say “ Public chain 2.0”, Its underlying design philosophy , It is completely different from the existing public chain , It is possible to really solve “ Impossible Triangle ” The problem of .

In many public chains , It seems that none of them can really ​ Of ​ Solve this problem
