People gather firewood and fire. The block chain in the high area is really “on fire.”

Time:2020-3-17

Blockchain has become the “new darling” of the world this year, and is favored by all walks of life. With the status of blockchain rising to the height of national strategy, the government departments also regard blockchain as an important breakthrough of independent innovation of current core technology. The concept of blockchain has really “caught fire” since then. TV, radio, social media, etc. are promoting blockchain in different ways.

Nowadays, blockchain is really a “firewood gathering and flame raising” technology, which is full of curiosity and subversive from top to bottom. Everyone knows blockchain differently.

Money free blockchain in the eyes of the government

At the collective learning meeting of the Political Bureau of the CPC Central Committee, the blockchain was valued by the high-level of the country. Professor Chen Chun, Professor of Zhejiang University and academician of the Chinese Academy of engineering, gave a wonderful speech to the Political Bureau of the CPC Central Committee. In his speech, Professor Chen mentioned alliance chain for many times, and explained the technological breakthrough and future development direction of alliance chain in depth. He said that the blockchain of the alliance chain is not only friendly in supervision, but also has the characteristics of high performance, high availability and protection of security and privacy.

Professor Chen said that they have benefited a lot from the government departments, and they also have a new understanding of blockchain. However, blockchain can solve the traditional Internet technology difficulties. Before that, the government had put forward the slogan “Let information run more, let people run less”. So far, few government departments have really achieved this slogan, which also has a bad impact on the hearts of the people. The development of blockchain technology is a piece of cake to solve the problem of information island without sharing and exchanging data. Through distributed accounting, the data of multiple parties can be shared, while each party can still keep its own data, and the privacy of the data will not be disclosed. For the government, they think blockchain is alliance chain, which has nothing to do with currency.

As you all know, Alibaba launched ant blockchain, Tencent recently launched Tencent blockchain, Baidu’s super chain has been under development for a long time, these Internet companies are launching their own blockchain, and they have not issued currency. Even if these blockchains do not issue currency, they can effectively solve the problem of information transmission between different organizations in their own ecology, and can make the cooperation between companies and between companies, and between companies and customers closer.

Blockchain technology in the eyes of enterprises

Although this is the first year of public chain, there are few public chain applications on the market, let alone alliance chain. However, the projects known as blockchain are flourishing.

In fact, the Central Bank of China has long implemented a check digitization system based on blockchain, which is mainly aimed at the bill financing discount behavior of enterprises. The system aims to combat financial fraud and reduce the cost of printing checks. But the country’s public information is extremely scarce, which has a lot of reasons.

In fact, it’s not hard to analyze. Compared with the traditional bill system, the biggest difference is that the system is loaded with smart contracts, in the words of the central bank itself:

“Based on the analysis of digital bill and its transaction characteristics, we have preliminarily completed a set of digital bill technology infrastructure relying on blockchain technology and taking smart contract as the carrier.

Each digital bill is a program code containing bill business logic and corresponding bill data information. These digital bills running on the blockchain have independent life cycle and self maintenance business processing capabilities. They can support a series of core business types such as bill acceptance, endorsement transfer, discount, transfer discount and cash. Various business rules can be passed through smart contracts Programming to achieve. “

It can be seen that although the blockchain technology is applied in this system, there is only “smart contract”. Moreover, the application of smart contract in bill aspect must be taken for granted. At the same time, for the blockchain technology, the smart contract can only be regarded as one element, not the real core element of the blockchain.

So, what other elements can a real blockchain have besides smart contracts? In fact, blockchain has rich connotations, which can be said to be all inclusive, such as utxo, public-private key password pairs, digital fingerprints, distributed accounting, workload certification, etc. Although they form a large set of technologies in blockchain technology, each technology can be used separately from blockchain.

Utxo can change the traditional way of liquidation and realize“Transaction is liquidation”Its function can liberate the traditional finance from the complicated settlement and clearing links, reduce the intermediate links, and make the transaction more convenient.

The workload proved that anti spam was first developed; for example, elliptic hyperbolic cryptosystem is used in many Internet encryption applications.

However, there are many projects like this. Every project that uses one of these technologies claims to use blockchain technology, which can solve some application problems in the future, so as to increase the hype and attract the attention of customers and investors.

Disruptive technology in the eyes of technology geeks

In the eyes of technology geeks, blockchain really has a combination of blocks and chains just like its definition: block + Chain = blockchain.

The block is generally composed of the following parts:Transaction, block structure, random number.Here is a question. How do you think the blocks are divided? In fact, it is not through time, nor through the number of transactions within the block, nor through the size of the block, but through the proof of workload to calculate the random number. In other words, blocks are divided by POW workload proof.

So, how are these blockchains linked? Through specific rules or protocols, each blockchain is combined to form a chain blockchain.

Generally speaking, the formation of chain requires the following steps:

1. The selection of new blocks is generally based on the block chain that calculates the random number first;

2. Network propagation, broadcasting the newly generated blockchain to more nodes this morning;

3. The formation of long chain, the chain that plays a role of link between blocks.

This is the definition of block. Let’s take a look at the definition of chain again: a block by block, combined by specific rules, forms a chain.

In fact, the real chain formation is far more than these points. In the process of formation, different data of different nodes in the whole network should be converged into the process of certain and identical data.

At present, in the blockchain world, these geeks think that only projects with pow workload certification are the most orthodox blockchain projects. For them, blockchains are basically public chains, and other private chains and alliance chains are “pseudo blockchains”.

Blockchain in the eyes of the public

In the eyes of the public, blockchain is a virtual world dominated by transaction and digital currency. However, with the introduction of token economy, we have a new understanding of blockchain.

Tong Zheng economy is a very important concept in the field of blockchain. Many tycoons are very optimistic about Tong Zheng economy. They think that the most important thing that blockchain ultimately contributes to society is Tong Zheng economy. Tong Zheng economy will provide a strong cooperation mode for people, and accurately quantify the contribution of everyone in the system, so as to greatly stimulate the participation of every participant Situation, greatly improve work efficiency, and pass economy will eventually subvert the existing company system.

For example, many content platforms do not match the blockchain at all. They are a real centralized platform and have nothing to do with blockchain decentralization. What can be similar to blockchain is that it issues coins based on blockchain, that is, pass.

At present, the vast majority of dapps with blockchain technology in the currency circle are only based on the currency circle. In addition, they are no different from traditional Internet projects.

Of course, the action of issuing coins is of great significance. In a small way, it makes everyone intuitively feel the existence of blockchain; in a large way, it can trigger a big wave of Tong Zheng economy.

summary

No matter who knows the blockchain, they are only hearsay knowledge in the past. Those who really understand the blockchain are focused on exploring the core of blockchain research and development. Today, blockchain gives the world a different face, so we should have a new understanding of blockchain, and we are full of confidence and expectation for the future of blockchain.
