『一』What are the mainstream blockchain technologies?

This article attempts to provide an overview of blockchain-related technology schools and mainstream platforms, as a guide for learning the blockchain technology system. The guide is intended to inspire discussion and promote consensus in the blockchain development community. The schools of blockchain technology plan ahead of the battle. If you want to invest in the field of blockchain development, you must at least find out who the current players are and what their respective opinions and strengths are. There are no certain rules for dividing blockchain technology schools. As far as I can see, there may be the following four ways: The first is to divide it into public chain, private chain and alliance chain according to the node access rules. The representatives of the public chain are naturally Bitcoin and Ethereum, the private chain is the most famous R3 Corda, and the representative work of the alliance chain is Fabric under the name of Hyperledger. Public chains focus on anonymity and decentralization, while private chains and consortium chains focus on high efficiency, and often set entry barriers. These differences between public chains, private chains and alliance chains are all reflected in technology. For example, private chains and alliance chains assume that the number of nodes is not large, and the PBFT algorithm can be used to form a consensus. The public chain assumes a large and dynamically changing node network. Using PBFT is too inefficient, and only a lottery-like algorithm can be used to determine opinion leaders. This means that it is difficult for private chains and alliance chains to become public chains, and although it is easy to use public chains to make alliance chains or private chains, it is not plug-and-play. Scholars cannot ignore this difference. The second is that according to the sharing goal, it is divided into two groups: shared ledger and shared state machine. Bitcoin is a typical shared ledger, and Chain and BigchainDB should also fall into this category. These blockchain systems share a general ledger between various nodes, so it is more convenient to connect with financial applications. In another large type of blockchain system, each node shares a state machine that can complete Turing complete calculations, such as Ethereum and Fabric. They all change the state of the shared state machine by executing smart contracts, thereby achieving various complex functions. . The third is to divide the blockchain system into three generations: 1.0, 2.0 and 3.0 according to the intergenerational evolution described by Melanie Swann. Among them, 1.0 supports decentralized trading and payment systems, 2.0 supports industry applications through smart contracts, and 3.0 supports decentralized social systems. Bitcoin and Chain should belong to the blockchain 1.0 system, while Ethereum and Fabric are blockchain 2.0 systems. There is currently no successful blockchain 3.0 system, but there is one unsuccessful attempt, which is the famous The DAO . The fourth is that according to the core data structure, it is divided into two factions: blockchain and distributed ledger. The blockchain school really implements a chain of blocks as the core data structure in the system, while the distributed ledger school only absorbs the spirit of the blockchain and does not really use a blockchain as the core data structure. , or although it is temporarily used, it is stated that the Zhuangwu blockchain is intended to be a distributed ledger. If time and opportunity come together, it may not be impossible to replace it. Mainstream blockchain technology platformInterpreting the divisions of schools can still only be used to point out the country and brag about the truth. To start, there must be an entry point. It is said that there are thousands of blockchain currencies, but there are only dozens of technology platforms worth paying attention to. If you want to enter the field of blockchain development, lay a good foundation, practice good skills, and get a few good ones. offer, there are only a handful of platforms worthy of in-depth study and study. The first, of course, is Bitcoin. As the first and most successful and important model project of the blockchain, Bitcoin has been online for more than eight years without any serious security and operation and maintenance incidents. Its stability and power can be called contemporary software. System model. Bitcoin Core is an open source software with high code quality and good documentation. From the perspective of learning blockchain principles and mastering core technologies, Bitcoin Core is the best entry point to learn authentic blockchain technology. . Of course, Bitcoin Core is written in C++, and uses some C++11 and Boost library mechanisms, which puts higher requirements on learners' C++ level. Another advantage of learning Bitcoin platform development is that you can connect with the prosperous Bitcoin technology community. There are currently many people working on improving and upgrading Bitcoin. The more people there are, the more power there is. Newer ideas and technologies such as Segregated Verification, Lightning Network, and Sidechains have all taken the lead in being implemented in the Bitcoin community. For example, Blockstream, the main leader of sidechain technology, is led by crypto currency veteran Adam Back, and Blockstream is one of the largest contributors to Bitcoin Core, so some sidechain-related technologies are the most discussed in the Bitcoin community. However, there is great controversy as to whether Bitcoin, as a typical blockchain 1.0 system, is the best technical platform to support other types of blockchain applications. In addition, not everyone has the ability and necessity to be proficient in the underlying technology of blockchain. So for those who are eager to rush into the blockchain field to do (quān) things (qián), the more straightforward learning goals may be Ethereum and Hyperledger Fabric. Smart contract development using Solidity on Ethereum is the easiest way to get into blockchain development, bar none. Ethereum's ideals are very grand. Because it is equipped with a powerful Turing-complete smart contract virtual machine, it can become the mother platform of all blockchain projects and is the big turtle that carries the entire blockchain world. Developing a cryptocurrency similar to Bitcoin on Ethereum is an out-and-out small goal. Generally, experienced developers can get started with the guidance of the documentation in half a day to a day. The question is, what happens after you get started? Can you conquer the world just by writing Solidity? This is highly doubtful. We can also say the other way around, if Ethereum + Solidity is the ultimate solution for blockchain, then why are there so many blockchain technology schools? In particular, Ethereum doesn’t seem to give the real world massive centralizationThe organizations have left a way to survive, and this completely uncompromising revolutionary attitude may also become an obstacle to the promotion of Ethereum. The current development of the Ethereum project is not going well. A more prominent problem is that there are too many projects and power is dispersed, resulting in uneven project quality. But despite this, compared with other blockchain 2.0 platforms, the development environment provided by Ethereum is the simplest and most complete. It is absolutely necessary for people who are new to blockchain to learn Ethereum to establish the most "authentic" understanding of blockchain and smart contracts. The third branch of the mainstream blockchain technology platform is Fabric, which is Hyperledger’s first and most well-known incubation project. Fabric first came from IBM's Open Blockchain project. By November 2015, IBM handed over the 44,000 lines of Go language code that had been developed to the Linux Foundation and incorporated it into the Hyperledger project. During a hackathon in March 2016, Blockstream and DAH merged their respective codes into Open Blockchain, which was later renamed Fabric. So far, Fabric and Sawtooth Lake provided by Intel are listed as the first-level incubation projects of Hyperledger, but the former has received far more attention than the latter. From a technical perspective, Fabric has a good idea, and its focus is to meet the commercial needs of enterprises, such as solving transaction volume issues. As we all know, Bitcoin’s biggest shortcoming is its upper limit of 7 transactions per second, which is completely unable to meet practical needs. Fabric's goal is to achieve 100,000 transactions per second. This volume is close to the instantaneous peak of the Double Eleven transaction volume that just passed, and can fully meet industry-level applications under normal conditions. Fabric is developed in Go language and also provides APIs in multiple languages. It is particularly worth mentioning that Fabric makes full use of container technology. For example, its smart contracts run in containers. This is also a benefit that Go language brings to Fabric, because the static compilation and deployment characteristics of Go language are very suitable for developing programs in containers. Fabric also has some features, such as its membership service that can set up node access review, which is a typical alliance chain feature. Another example is that its consensus algorithm is customizable. The shortcoming of Fabric is that the system is relatively complex. Although it has documentation, it is difficult for developers who lack experience to learn it. However, because of its clear positioning and catering to the mentality of many companies, many institutions are already secretly developing alliance chain projects in the industry based on Fabric.

『二』How to develop blockchain

Share Zone View Network:

The application scope of blockchain technology is still very wide, based on decentralization , with the characteristics of trustless, collective maintenance, reliable database and other characteristics, its application in the financial industry is the first step forward.

Blockchain is the underlying technology of Bitcoin. Blockchain is playing an important role in many aspects.The application development of currency is already mature.

『三』 How to judge whether a blockchain project is worth investing

1. Project details

Project details are generally published by the project party on some ICO platforms The platform will be responsible for review, and detailed relevant information must be submitted when publishing. Available for user query. The following are what we need to refer to:

◆Whether the project team member information is fake

◆Whether the official website has been recently filed

◆Whether the total project quota is reasonable

◆Whether the additional issuance is excessive

◆Whether the project token allocation is reasonable

◆Whether the project development plan and development plan are clear

II. Product Analysis

Type: application, platform, underlying technology

Carry out corresponding analysis based on different blockchain projects to determine whether the project is suitable for development through blockchain technology and compare Analyze existing products in the industry. For example, a certain project is currently building a decentralized content distribution platform. We can refer to the better TOUs in the industry. As a unicorn in the field of content distribution, Toutiao has grown since its launch in 2012 and now has 500 million registered users and nearly 100 million DAU.

Profit model: e-commerce advertising, information flow advertising to monetize traffic,

Product advantages: large number of users, classified push of information based on specific algorithms, user experience Good, user habits are developed

Financing experience: Series C, US$1 billion

Based on the above information and comparing it with the project’s white paper, determine what are the real advantages of this blockchain project? If the project white paper cannot clearly describe the product architecture and just talks about concepts, then it is very likely that the product is unreliable.

3. Market analysis

Competing products: not only Sina, Sohu, Tencent, NetEase, Phoenix, Yidian, Zaker, Online News, Zhihu Daily and other major platforms. There are also a series of vertical content products competing with it.

7. Team composition analysis

◆Whether there are big names in the team

Whether it is technology big names: such as stratis CEO Chris Trew, Eyal Hertzog of the Bancor founding team, such as Tenx Investors include Ethereum founder Vitalik Buterin and Fenbushi Capital partner Shen Bo.

The initiator of a certain blockchain product crowdfunding project is Yang Mouke, the former co-founder of Bitcoin China, who launched the ICOcoin project. Or maybe the initiator of the blockchain project is Mr. Li, the “richest man” in Bitcoin in China.Come and publish the Press one project. This can all mean that this project is reliable in a certain sense. Of course, there are exceptions, such as the recent case of Mr. Li, whose project caused outrage in the entire circle.

◆Is the team structure scientific?

Legal consultants, industry consultants, project management committees, third-party organizations

8. Reference blockchain project rating websites< /p>

Relatively reasonable, there are many rating websites, and the rating standards of each platform are also different. There may be a big gap in the ratings given by the same project on different platforms. At this time, we are needed

I have a deep understanding of the basic knowledge related to blockchain and am capable of certain self-judgment. Don’t trust experts. Many so-called experts may have interests tied to the sponsors of blockchain projects.

9. Direct communication

The last point is also the most important. Whether it is a face-to-face road show, or communication in a forum or community, people can intuitively understand whether the initiator of this project is reliable. Whether it is a blockchain product project or some technical questions, the project side can answer them. Whether it is reliable or not can be known once tested.

『四』What technology development is needed for blockchain

What technology development is needed for blockchain:
1. Blockchain theory: Blockchain developers need to Being familiar with the theoretical knowledge of blockchain is the most basic requirement for a blockchain developer. The content includes blockchain network architecture, decentralization and other related application technologies. Expanding technical theory is mastery of Ethereum development.
2. Smart contract: Smart contract is a string of codes that blockchain developers need to write in blockchain programming language. It is a trust mechanism developed after imagining logic according to different scenarios, aiming to eliminate the intervention of third parties. Create an efficient and high-trust blockchain network. Blockchain developers need to realize automatic execution of this string of code, and the operation effect is irreversible.
3. Cryptography: Many blockchain application scenarios have high encryption, and point-to-point encryption mode is a characteristic of cryptography. By studying cryptography, blockchain developers understand encryption concepts such as wallets, keys, and a wide range of encryption and decryption technologies
4. Distributed architecture: Blockchain developers must understand the functions of distributed architecture and networks . Decentralized network is the foundation of the blockchain architecture. The transmission of information in the blockchain network must follow a decentralized approach so that everyone can enjoy the same network rights.

『五』How to develop a block into a blockchain

1. The development of a block into a blockchain requires the software Go. Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.
2. Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it is "unforgeable", "leaving traces throughout the process", "traceable" and "open and transparent"Features such as “collective maintenance”. Based on these characteristics, blockchain technology has laid a solid foundation of "trust", created a reliable "cooperation" mechanism, and has broad application prospects.
3. From a technological perspective, blockchain involves many scientific and technical issues such as mathematics, cryptography, Internet and computer programming. From an application perspective, simply put, blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, full traceability, traceability, collective maintenance, openness and transparency. These characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for creating trust in the blockchain. The rich application scenarios of blockchain are basically based on the ability of blockchain to solve the problem of information asymmetry and achieve collaborative trust and consistent action among multiple subjects.

『Lu』 Want Understand what are the development and applications of blockchain

The application scope of blockchain is spread across many industries

At present, one of the earliest applications is Bitcoin. The underlying technology platform of the blockchain, as the name suggests, is the Bitcoin network

Other underlying technologies of the blockchain now include IBM's Febric, Yinlian's blockchain underlying technology platform, etc.

Development Up to now, the application of blockchain mainly has the following directions: 1

Financial industry

In the financial industry, blockchain can be said to be the most popular FinTech (financial industry) in the world. Technology)

There are also endless application cases in the financial industry, such as: Sunshine Insurance launched the "Blockchain Aviation Accident Insurance Card" on July 29, 2016

Most airlines Accident insurance will only issue insurance claims when an aircraft accident occurs. In most cases, fake insurance policies bought by customers are not easy to detect. Based on blockchain technology, the entire process of card orders from source to customer circulation can be traced. Not only can all parties Checking the authenticity of the card can also facilitate subsequent processes, such as claims settlement

At the same time, without middlemen, the unit price of insurance cards will be significantly reduced

The economic benefits: this product Purchase one for 60 yuan, which can be used by 20 people. You can get up to 2 million yuan of aviation accident insurance each time, which is equivalent to getting 2 million yuan of protection for 3 yuan each time.

It saves consumers' expenditures and insurance companies' costs to a great extent

There are also commercial bank collaterals released by Yinlian Technology in September 2016. This product is mainly used for real estate. Registration of assets such as vehicles and vehicles to prevent repeated mortgages and apply the blockchain consensus mechanism to improve inter-bank work efficiency
