Columbus GAC public chain blockchain

1.

Public chain, also known as "public chain", refers to the blockchain that anyone in the world can enter the system at any time to read data, send confirmatory transactions and compete for bookkeeping. The public chain is generally considered to be "completely decentralized", because no indivial or institution can control or tamper with the reading and writing of data in it. In terms of application, blockchain public chain mainly includes bitcoin, Ethereum, super ledger, most counterfeit currencies and smart contracts. The ancestor of blockchain public chain is bitcoin blockchain, which has the following characteristics:

1, open source code

upload the code to GitHub, and everyone can get complete blockchain data by downloading, Accept the test of the public

2, complete decentralization

anyone can become a node, each node is open, everyone can participate in the calculation of the blockchain, any node is not permanent, but phased, and any center is not mandatory for nodes. Anyone can read and send transactions, and transactions can be effectively confirmed on the blockchain. Anyone can participate in the consensus process. The consensus process determines whether a block can be added to the blockchain and the exact current state. Everyone can get financial reward from it, which is proportional to their contribution to the consensus process. These public chains are generally considered to be "completely decentralized"

3. Developing decentralized applications

through this public chain, developers can easily develop centralized applications. Public chain can protect the rights and interests of users from the influence of program developers

This is two different concepts. According to different standards, blockchain can be classified into three categories:

& # 8195&# 8195; 1) According to the network scope of blockchain, it can be divided into public chain, private chain and alliance chain

 &# 8195; 2) According to the docking type of blockchain, it is divided into single chain, side chain and interconnection chain

 &# 8195; 3) According to the display environment of blockchain deployment, it can be divided into main chain and test chain

the main chain can be understood as a formal online and independent blockchain network, while the public chain refers to a blockchain that can be read by anyone, can send transactions and can be effectively confirmed by anyone, and can participate in its consensus process

3. Man, you're not technology, are you; There are too many. All kinds of ghosts and ghosts come to evaluate the blockchain. Often, these people's understanding of blockchain is just superficial, even nonsense. I used to learn a little bit about technology development, but later I was afraid of being bald and started working in the media instry, although I found that there was still a risk of being bald after I joined the instry
to get down to business, let me analyze the routine of media platform from the perspective of media. A company needs a certain public opinion environment when it needs to develop, especially in emerging instries. What kind of things will media do for emerging instries? They will publish false reports and even malicious remarks about the instry. It's often the work of small media companies, so why do they do it? It's very simple to earn traffic. The most eye-catching is often the heated comments. This kind of articles can easily incite netizens' emotions and increase their reading volume. In this way, the flow of cash is a very simple thing, then the capital of advertising will become higher. The more vertical reports the article has, the more valuable the vertical ads will be. For example, if I am a we media practitioner and I have been making untrue comments about the blockchain instry, then one day a blockchain company wants to send a report to me, then I can ask for a price
most of the untrue comments on the Internet can be divided into several categories: the spread of falsehoods between small websites and small media. Rumors start from taking out of context and making up, and then they will be further upgraded. The first wave of taking out of context and making up articles will be used to intercept part of the evidence to spread the upgraded version of rumors. When many stars or company leaders see this, their first reaction is: when did I say this&# 160; The second reaction is to laugh. The media, alas, is normal. More helpless, spend money to find the media to explain it, another group of people said you wash white. Don't make a statement and say you acquiesce. This vicious circle wave after wave, some companies are not so destroyed? In view of the above content, I give the questioner a clear way to distinguish, first: pay attention to check the level of the media that issued the article, and be happy with what the small media say, but don't take it seriously. Second: is it released from its official platform? If not, no one knows so much inside information
from the perspective of technology, what's wrong with blockchain technology? It's just an emerging technology. In fact, it can't be counted. It was first applied to bitcoin. It's just that there is a delay for the general public to come into contact with these, just as it will take a few years for the routine model of big cities to develop into small cities. Columbus cat does have a certain strength in the technical circle, and its technical reserves are quite sufficient. Just want to achieve comprehensive business development, it will certainly need a long march. For example, we may have developed the online payment system long before Taobao came out, but the technology can not be applied immediately. First of all, you have to convince others to believe you, so that you can really apply it. Father Ma succeeded in persuading Chinese women, so he succeeded. Blockchain itself is a cross era technology. To better promote it, more dedicated entrepreneurs need to work together.

4. Columbus cat takes the development of blockchain technology as the core to drive the application of entities. Their main chain mainly has the following innovations: 1. Index of blocks; 2; 2. Using distributed nodes to build storage system; 3. Blockchain distributed VPN&# 160; 4. Resist quantum attack; 5. Structured data storage; 6. Big data cluster analysis; 7. Quantum key distribution; 8. CUDA based hardware and software combination blockchain hardware accelerator.

6. It's true, it's true, it's true. But there may be small changes in the future

7. 1. Alliance chain
the openness and decentralization of alliance chain are limited. Its participants are screened out in advance or specified directly. The read permission of the database may be public, or it may be limited to the participants of the system just like the write permission. Currency exchange of digital currency
2. Public chain
public chain is that every node in the blockchain is open, everyone can participate in the calculation of blockchain, and everyone can download complete blockchain data, also known as blockchain ledger
public chain refers to the process that anyone in the world can read and send transactions, and transactions can be effectively confirmed on the blockchain, and anyone can participate in the consensus process. The consensus process determines whether a block can be added to the blockchain and the exact current state
3. Private chain
202. What is private chain
private chain refers to the blockchain whose write permission is only in the hands of one organization. Read access is either open to the public or restricted to any extent. Related applications include database management, auditing, and even a company. Although in some cases, we hope it can have public auditability, in many cases, public readability is not necessary. It can be said that each of the three chains has its own advantages.

8. Generally speaking, the competition of blockchain public chain is fierce now, because the public chain project is the foundation of blockchain ecology, and the public chain is a super project with huge system, extremely complex and extremely difficult. At present, the overall market situation is similar to that in the early days of the computer system, which started with the development of technology; Linux operating system and UNIX (Younis) are changing, but in the end, windows dominates and apple OS coexists for a long time< br /> 
at present, Ethereum and EOS are the most popular public chains. However, the market value of EOS has plummeted after its epic loophole recently, which has been downplayed by many media. Often the most promising at the beginning may not win in the end. Recently, because of their innovative consensus algorithm, they proposed quite innovative CPOs and focused on a new public chain project

their name is gaiaworld public chain, and their CPOs consensus algorithm is their core technology. Specific technical details can go to the official website to see the white paper, in short, TPS speed has reached a new height, faster than Ethereum, and can support the layout of large projects< br /> 
at the same time, they have innovated two other technologies. Parallel chain technology can make it easier for other developers to release side chains, and then aegis protocol, which is a specific smart contract protocol&# 160;< br /> 
now there are so many air projects, it's really hard to distinguish the good from the bad, but I think the technology platform is the future
hope to adopt
