This article shows you how to understand hyperledger super ledger technology, the content is concise and easy to understand, it will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

Hyperledger super ledger is an open source project launched by the Linux Foundation in 2015 to promote blockchain digital technology and transaction verification.

1. Health background

In 2009, Bitcoin decentralized network was officially launched, as the first application of blockchain technology, Bitcoin proved that blockchain technology could bring about technological changes in the entire Internet technology. The blockchain technology behind Bitcoin is called blockchain 1.0.

In 2013, the then 19-year-old Vitalik Buterin (known as V God in China) proposed the blockchain technology architecture based on intelligent contract-ethernet Fong Foundation, which was established in 2014 as the next generation blockchain system following the Bitcoin blockchain architecture. Ethernet Fong has now become the most famous blockchain project in the world. The technical architecture of block chain based on intelligent contract represented by Taifang is called Block chain 2.0.

In 2015, the Linux Foundation absorbed the advantages of all previous blockchain technologies and was in the original intention of realizing commercial applications, and launched the super ledger open source project. so far, super ledger is the most recognized and used blockchain technology framework by enterprises.

2. The connection and difference between Super ledger and Etay Square.

ETaifang is a platform based on the public chain, which allows all players to deploy and invoke intelligent contracts on the public chain, and the intelligent contracts and data on the chain are decentralized and stored. Turing's complete Solidity allows players to develop any intelligent contract they want to achieve, and the data is open and transparent.

But Etay Fong ignores the basic requirement of an important business application-data privacy.

Companies are saying that their private data should be properly protected, based on the fact that the block chain of Ethernet Fong will reveal details of business relationships that should not have been leaked to competitors. In the same industry, the circle is already small, and the system that supports the transaction between the two parties should not disclose the transaction of either party.

For the sake of privacy in business applications, the Linux Foundation launched the super ledger in 2015, which can provide a mechanism to ensure the privacy of business data. On the basis of decentralization at the bottom of the block chain and ensuring data traceability and security, it provides a membership mechanism, and members can query transaction information only when authorized. To a certain extent, super ledger is not 100% decentralized.

After the etherfang transaction, you need to pay the miner Gas, the deployment cost in the public chain is too high, and the super ledger does not need to pay the transaction fee.

3. Super ledger is a world that covers many networks.

The super ledger is a trading network based on alliance chains.

Each industry field or individual can create their own trading network (also known as alliance chain), store and interact with their own decentralized business data within the trading network, maintain their own industry books, and provide membership data permissions to the outside world. Authorized enterprises and institutions can view the data of their accounts in the alliance chain (data can be disclosed in accordance with certain business rules) In addition, multiple account books in the trading network can have relevant API to exchange data with each other, so many transaction networks are connected to each other to form a super account book system, as shown below:

No super ledger trading network contains four different types of service nodes, which coordinate with each other to complete the function of the whole blockchain system, and Fabric can decouple different nodes.

After the transaction network receives a piece of transaction information, the endorsement node first checks and endorses the transaction to initially determine whether the transaction is legal, and then the sorting node collects all transactions occurred in the current time period, sorts them and organizes them into blocks. finally, it is submitted to the confirmation node, and the confirmation node checks the transaction result again, judges the legitimacy of the transaction, accepts the modification of the legal transaction to the account book, and writes it into the block chain. All the above nodes must be authorized by the certificate node in the form of a certificate, and the node that does not have a legal certificate cannot participate in all aspects of the transaction.

4. The technical framework of super ledger.

The technical architecture of super ledger is mainly divided into three parts:

Membership, Block chain, Code on chain

The technical architecture of the super ledger is as follows:

Membership services are responsible for managing identification, privacy and confidentiality on the Internet.

The blockchain service is responsible for managing distributed books.

The code on the chain is responsible for providing a safe and portable sandboxie load path to verify that the node executes the code on the chain. The whole environment is a safe and closed container, and the code on the super book chain is mainly managed and executed based on Docker.
