A. Blockchain, 4 types, how much do you know

——Hello, I am mentality, focusing on sharing my understanding of blockchain and investment thinking. hope this helps.

Based on different usage requirements and scenarios, blockchain is divided into 4 types: public chain, alliance chain, private chain and hybrid chain.

1. Public chain

Public chain means that anyone at any node in the world and at any geographical location can enter the system to read data, send transactions, and compete. Blockchain that participates in consensus such as accounting. No institution or individual can tamper with the data in it, so the public chain is completely decentralized.

Bitcoin and Ethereum are both representatives of public chains. Public chains generally encourage participants to compete for accounting (i.e. mining) by issuing tokens to ensure data security and consensus updates.

Bitcoin generates one block every 10 minutes on average, and its POW mechanism is difficult to shorten the block time. The POS mechanism can shorten the block time relatively speaking, but it is more likely to cause forks. So the transaction needs to wait for more confirmations before it is considered safe.

It is generally believed that a block in Bitcoin is secure enough after 6 confirmations, which takes about an hour. Such a confirmation speed is difficult to meet commercial-level applications. Therefore, public chains such as ETH and EOS that support more writing speeds are constantly developing.

2. Alliance chain

Alliance chain refers to a blockchain that is jointly participated and managed by several institutions, with each institution running N nodes.

The data of the alliance chain only allows different institutions in the system to read, write and trade. The PKI-based identity management system transactions or proposals are initiated through digital certificates and are verified by the joint signature of the participants. A consensus is reached, so there is no need for proof of work (POW), and there is no digital currency (token), which improves the efficiency of transaction completion and saves a lot of computing costs (computing hardware investment and electricity energy consumption).

Normally, nodes participating in the alliance chain will be divided into different read and write permissions, which can support more than 1,000 data writes per second.

3. Private chain

Unlike the public chain, which is completely decentralized, the private chain’s access rights are controlled by an organization, and the participation qualifications of each node are controlled by the organization. Authorization control.

Since the participating nodes are limited and controllable, private chains often have fast processing speeds and can support more than 1,000 data writes per second, while reducing the transaction costs of internal nodes.

Nodes can participate under real names and therefore have financial attributes to confirm identity. The value of the private chain is mainly to provide a safe, traceable, non-tamperable, and automatically executed computing platform, which can simultaneously prevent security attacks or tampering with data from both internal and external sources, which is difficult to achieve in traditional systems.

The application scenarios of private chains are generally within enterprises, such as inventory management of branches, summary statistics of data from various places, etc. It can also be used in areas that can be supervised by the public, such as government budgeting and execution. Large financial groups are also currently inclined to use private chain technology.

4. Hybrid chain

When the respective advantages of public and private chains are combined, a hybrid chain will appear. The development of hybrid chains is difficult, but the prospects are broad.

In the future market, there will definitely be giant companies that develop underlying technologies and protocols. These giant companies will set up public chains, private chains or alliance chains for different purposes, based on performance and security. and the different needs of application scenarios, and then grafted on applications in different industries. For example, a communication public chain that supports high concurrency, a payment alliance chain that focuses on security, etc.

C. What is the development trend of blockchain

2018Since the beginning of the year, the blockchain industry has been booming. Blockchain-related exploration and application are no longer limited to the underlying platform. Internet giants and financial giants have strengthened the use of blockchain in the fields of finance, public welfare, commodity traceability, etc., especially in the financial field, with blockchain technology as the core. Applications are being implemented faster.
The blockchain industry is in a stage of rapid development
my country’s blockchain industry is currently in a stage of rapid development. According to the "In-depth Analysis Report on Business Model Innovation and Investment Opportunities in the Blockchain Industry" released by the Qianzhan Industry Research Institute, as of the end of March 2018, the number of blockchain companies in my country with blockchain business as their main business reached 456 From upstream hardware manufacturing, platform services, and security services, to downstream industrial technology application services, to industry investment and financing, media, and talent services to ensure industrial development, companies in various fields are basically complete.
Judging from the application scenario classification of the TOP20 companies on the ranking list, in addition to 13 companies focusing on blockchain infrastructure and platform construction such as underlying platforms and blockchain hardware, the application scenarios of blockchain have gradually become richer. . Judging from the distribution of industry subdivisions, there are 7 industry application companies, mainly Internet companies (Alibaba, JD.com, Tencent) applied to public welfare and product traceability, as well as innovations in the evolution of financial companies (Ping An, China Merchants Bank, Bank of China) Fintech applications such as supply chain finance, bill and transaction clearing.
Since blockchain can make information non-tamperable and eliminate the possibility of data falsification from the root, the financial industry, especially those with higher requirements for real data, will embrace blockchain more actively.
Analysis of blockchain development trends

In addition, as an emerging technology, there are still many technical difficulties when applying blockchain in the actual production environment of the financial industry, such as throughput, scalability, consensus mechanism, privacy and security, and reliability. Management etc.
Technological innovations such as blockchain are of great significance to the financial industry and are expected to accelerate the process of "credible digitalization" and continue to drive finance "from virtuality to reality."

D. The future development prospects of blockchain

1. Blockchain has become the forefront of global technological development and opened up a new track for international competition. Blockchain will become a new key infrastructure to further accelerate the development of the digital economy, lead a new round of global technological change and industrial change, and become a key factor in technological innovation and modelling.The “source” of innovative innovation. The world's major developed countries will further pay attention to blockchain technology, intensively introduce relevant policy plans, increase industrial support and guidance, and enhance the competitiveness of their country's blockchain technology and industry.
2. The digital currency bubble gradually cools down. With the spread and popularization of the concept of blockchain technology, more and more people will realize that Bitcoin is not the same as blockchain, and various air coins will be gradually eliminated. Blockchain technology innovation will return to a more rational track. Technical features such as decentralization, multi-party collaboration, and anti-calculation tampering will be highly valued by relevant industries. Some industries with strong innovation capabilities will continue to emerge with blockchain applications that have been transformed based on industry characteristics.

E. How much does it cost to develop blockchain software

There is no answer to this question, because blockchain software is just a large field and requires specific analysis of specific issues. Asking this question is like asking how much it costs to buy a house.
Blockchain software is divided into several categories
For example, exchanges are the most popular, ranging from simple tens of thousands to fully functional hundreds of thousands
There are also blocks For chain games, it depends on the game settings. Generally speaking, there are hundreds of thousands to hundreds of thousands
For others, it depends on the specific category
