Today, I will talk to you about what is Hyperledger and how Linux builds an open platform around Intel's blockchain project. Many people may not know much about it. In order to make you understand better, the editor has summarized the following content for you. I hope you can get something according to this article.

When visiting blockchain meetings and following blockchain news, you will inevitably encounter the Hyperledger of the Linux Foundation. It's relatively easy to understand cryptocurrencies like Bitcoin and Ethernet Fong, but not Hyperledger. But if you do more research, you will find some exciting non-monetary, industrial block chain applications.

What is Hyperledger?

Let's start with what Hyperledger is not. First of all, it is not a company, not a cryptocurrency, not a blockchain. Hyperledger is more like a hub for the development of open industrial block chains. On the Hyperledger website, it explains:

"Hyperledger is an open source project aimed at promoting the development of cross-industry blockchain technology. The project was led by the Linux Foundation in December 2015 and includes leaders in finance, banking, the Internet of things, supply chain, manufacturing and technology."

Hyperledger does not support bitcoin or any other cryptocurrency. But the platform is very excited about blockchain technology. Because of the network itself, "there is a technology that promises a broader and more fundamental revolution than blockchain technology," the website said. " Blockchain has the potential to "build a new generation of trading applications that simplify business processes and legal constraints while building trust, accountability and transparency at its core."

So we make a lot of promises-we have Hyperledger. With it, the Linux Foundation aims to create an environment in which software developers and companies coordinate the construction of blockchain frameworks. The Linux Foundation created the platform in December 2015. In February 2016, it announced its first founding members, with 10 more members joining in March 2016.

Today, Hyperledger has an impressive list of more than 100 members. The list covers a wide range of well-known industry leaders. It includes mobile technology giants such as Airbus and Daimler, IT companies such as IBM, Fujitsu, SAP, Huawei, Nokia, Intel and Samsung, Deutsche B ö rse, American Express, JPMorgan Chase, BBVA, BNP Paribas and Wells Fargo. Blockchain startups like Blockstream,Netki,Lykke,Factom,bloq and Consensys. Many of the world's largest technology and financial companies met with some of the hottest blockchain startups at Hyperledger.

Hyperledger's "executive government" is a leader in a variety of industries. Most of the more than 10 executives have decades of open source experience and close ties with a number of industries. You will find leaders of Apache Foundation and W3C Consortium, engineers of IBM, and so on. Some members of Hyperledgers, such as Richard Brown and Tamas Blumer, have been working with Blockchain for many years. For its members, Hyperledger provides not only technical knowledge and software framework, but also a variety of contacts with the industry and developers.

In the early stages of Hyperledger history, something had to be given up. Brian Behlendorf, the executive director, was asked if there would be a "Hyperledger currency"-a unit of currency that runs on the Hyperledger blockchain. Behlendorf replied that the Hyperledger project itself would never establish its own cryptocurrency.

"you will never see the Hyperledger currency," he said. "by not pushing the currency, we have avoided many political challenges of having to keep the global currency consistent."

This decision confirms the strategic goal of Hyperledger to establish the industrial application of blockchain technology and completely separate it from the enrichment program that usually develops from the currency-based blockchain. It may be a little boring, but face to face with Hyperledger technology.

In addition, the charter outlines the goals of Hyperledger, such as mission guides. Accordingly, the platform aims to "create an enterprise-level, open source distributed ledger framework and code base" and create, promote and maintain an open infrastructure.

Somehow, this statement is still a bit vague. It outlines some kind of program, but it doesn't answer the big question about the pain point: what are all the world's leading companies and leaders doing at Hyperledger? What projects have they promoted? Who's in it?

Project

Hyperledger's "umbrella strategy" incubates and promotes a series of business block chain technologies, frameworks, libraries, interfaces and applications. Currently, Hyperledger is the moderator of the following projects:

1. Hyperledger Sawtooth: this is a modular blockchain suite developed by Intel that uses a new consensus algorithm called Proof of Elapsed Time (PoeT).

2. Hyperledger Iroha:Iroha is a project of several Japanese companies to create a project that is easy to merge blockchain frameworks.

3. Hyperledger Fabric: this is an IBM project. Fabric is a plug-in that can implement blockchain technology as the basis for developing advanced blockchain programs with flexible permissions.

4. Hyperledger Burrow: this project develops an intelligent contract machine with permission along the specification of Etay Square.

In addition to these framework projects, Hyperledger has several tool projects designed to make blockchain access and development easier and more effective. This is Cello, a blockchain as a service deployment model, Composer, a tool for building a blockchain business network, a resource manager for viewing, querying, and deploying transactions and related data on a blockchain, and Indy, a range of tools, libraries, and other blockchain-based digital identity components.

Hyperledger is clearly involved in a large number of non-currency blockchain projects. We took a closer look at the two most prominent projects: Sawtooth and Fabric. Both projects were created by large companies-Intel and IBM-and provided with Hyperledger as open source. Through Hyperledger, the company continues to press ahead with its blockchain project while inviting others to participate.

Intel's Sawtooth

Sawtooth Lake is Intel's modular blockchain suite. It is written in Python and is designed for use cases in many areas, from the Internet of things to finance. The main feature of Sawtooth Lake is that it supports licensed and unprivileged applications and deployments, and it uses the newly developed PoET consistency algorithm.

PoET uses new secure CPU instructions, and this CPU is often used in new processors built by Intel. Through these instructions, PoET ensures that so-called "leaders" are selected safely and randomly. This can be compared to bitcoin mining, where miners compete for one-time access to write blockchains. Apart from the bitcoin proof algorithm, PoET does not need special mining hardware.

To become a leader, each "validator"-equivalent to a node or miner-needs to use secure CPU instructions to request wait time. The validator with the shortest waiting time will be selected as the leader. The algorithm PoET works like a lottery ticket, and the price can get write access to the block chain.

There is no reward for leaders other than cryptocurrency. It's just part of running the software. As a result, there is no such fierce competition as cryptocurrency. Each node can use its CPU-as long as it is a new model and may be from Intel-and can participate for free for leaders to choose. What is Bitcoin mining is only a non-invasive part of Sawtooth Lake software.

Another innovation of Sawtooth Lake is the establishment and dissemination of transactions. The client builds the transaction and submits it to the validator. This includes the transactions they get in the batch and commit them fully. This is a similar but not exactly the same process, because when the cryptocurrency "miner" wraps the transaction into a block, Sawtooth solves the problem of interdependence of security authentication through this batch processing.

So far, Sawtooth has been tested in a variety of applications. Tests have recorded the seafood journey from the ocean to the table, using Internet of things sensors, from fishermen to supermarkets, to track ownership, ownership and parameters of the entire supply chain. Buyers can access complete and unencrypted records of the entire seafood chain. Blockchain increasingly discusses such use cases in supply chain and product history.

Sawtooth has also been tested to simplify the process of transferring bonds. The developer created a user interface for tracking and transferring bonds. With this, users can manage the entire portfolio of bonds on the blockchain. Another use case for the Sawtooth currently being tested is digital assets. Developers have built a platform to manage digital asset ownership on the Sawtooth block chain, which can manage a wide range of digital assets. The point of connection between applications, Sawtooth, seems to be a market for any type of digital asset built in the blockchain, and has provided a graphical interface for users.
