Is quark blockchain a public chain

1.

In the past, when it comes to blockchain, we always think of foreign procts, such as Ethereum. But when I talk about this topic today, I think more about China's own blockchain technology

at present, the mature application of blockchain technology is more concentrated in some public chain projects, because many application projects need to be developed based on this, so I think the current global landing direction is public chain projects, and it is still too early to talk about maturity. After all, bitcoin and Ethereum are still blocked, and many old problems have not been solved, There will be many new problems. The well-known ones are Biyuan chain, ulord (the project is abroad, but the technical party provides it in the domestic company, Hunan Tianhe Guoyun Co., Ltd.), quantum chain, Xiaoyi Neo, gongxinbao, etc

ulord is a point-to-point value delivery public chain. By building the underlying architecture of blockchain and digital resource distribution protocol, it supports third-party developers to build their own applications on top of their open source protocol, and works with many instry partners to build a complete ecosystem of blockchain technology and applications

based on various rules and protocols created by ulord, it is convenient to graft various digital resource application scenarios including text, pictures, music, video, software, etc., providing a direct docking platform for information creators and consumers. Third party developers can build their own economic system in ulord, or focus on building all kinds of applications around ulord, and use the ulordtoken in ulord as the voucher in the system

for example, an experience sharing platform can be built on ulord, where the experience sharers price the published experience, and the people who obtain the experience information trade on the platform, and each fee paid to the experience sharers will arrive at the account immediately; Proct promoters can publish ads on ulord, price ads, and people who are interested in ads can get certain profits by clicking on ads. The first mock exam is to separate information from the past, and to use platform or other centralized organizations to spread profit. This mode eliminates intermediate links, and information providers and consumers directly connect with Ulord, which ensures the maximization of the interests of the originator. p>

Blockchain includes public blockchain, joint (instry) blockchain and private blockchain. Public chain point-to-point e-cash system: bitcoin, smart contract and decentralized application platform: Ethereum

blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies

blockchain is an important concept of bitcoin. In essence, it is a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of bitcoin network transaction information, Used to verify the validity of its information (anti-counterfeiting) and generate the next block

extended data

according to the different degree of blockchain network centralization, three kinds of blockchains under different application scenarios are differentiated:

1. The blockchain with the whole network open and without user authorization mechanism is called public chain

2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain

3. All the nodes in the network are in the hands of one organization, which is called private chain

alliance chain and private chain are also called licensing chain, and public chain is called non licensing chain

blockchain features

1, decentralization. Blockchain technology does not rely on additional third-party management institutions or hardware facilities, and there is no central control. In addition to the self-contained blockchain itself, each node realizes information self verification, transmission and management through distributed accounting and storage. Decentralization is the most prominent and essential feature of blockchain

2. Openness. Blockchain technology is based on open source. In addition to the private information of all parties involved in the transaction is encrypted, the data of blockchain is open to everyone. Anyone can query blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent

3. Independence. Based on consensus specifications and Protocols (similar to various mathematical algorithms such as hash algorithm used by bitcoin), the whole blockchain system does not rely on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention

4. Safety. As long as 51% of all data nodes cannot be controlled, the network data cannot be arbitrarily manipulated and modified, which makes the blockchain itself relatively safe and avoids subjective and artificial data changes

5. Anonymity. Unless there are legal requirements, technically speaking, the identity information of each block node does not need to be disclosed or verified, and the information can be transferred anonymously

3. 1. Bitcoin 2, Ethereum: Ethereum is a kind of digital token of Ethereum, which is regarded as "bitcoin version 2.0". Using blockchain technology different from bitcoin, "Ethereum" developers need to pay Ethereum (ETH) to support the operation of the application. Like other digital currencies, they can be traded on trading platforms. 3. lettercoin: lettercoin (LTC, currency symbol:?) It is a kind of network currency based on "point-to-point" technology and an open source software project under MIT / X11 license. It can help users make instant payments to anyone in the world. 4. Dogcoin: dogcoin, known as "dogcoin / dogcoin", was born on December 8, 2013. Based on the crypt algorithm, dogcoin is the second largest virtual currency in the world after bitcoin in terms of number of users. 5. Yuan Bao coin: Yuan Bao coin is a virtual digital currency similar to bitcoin. The founder of yuanbaocoin is a group of bitcoin enthusiasts and the earliest supporters. However, after seeing the problem of bitcoin, he decided to do his best to develop an electronic currency suitable for Chinese people with the latest technology. 6. Diandiancoin: "ppcoin was pre released by sunny king on August 11, 2012 and officially released on August 19, 2012. Ppcoin's biggest innovation is that its mining method combines POW workload proof and POS equity proof. POS mining method only needs ordinary computers and clients to process transactions and maintain network security, so as to achieve the purpose of energy saving and security. 7. Katecoin: katecoin (KTC for short) is a virtual P2P digital currency that can be used all over the world. Point to point transmission means a decentralized payment system. 8. Quark coin: Based on six encryption algorithms (black, BMW, groestl, JH, keccak, skein), 9 rounds of super secure hash operation of virtual currency, 3 rounds of application of random hash function, quark coin has unique technical specifications. 9. Infinity coin: Infinity coin (IFC) is a new digital currency, which has more circulation advantages than bitcoin, and fills the short board of bitcoin in the field of commercial circulation and promoting commercial operation. 10. Common coin: common coin, English name popular coin, short for POC, was born on March 7, 2014. The total POC is close to the world population (7.057 billion).

the quark blockchain team promised not to conct any pre digging and selling of points, let alone any fund-raising activities such as ICO and private placement

quark blockchain is a kind of blockchain based on PHP language, and ultimately hopes to provide distributed web, distributed storage and distributed streaming media playback services through blockchain technology

the goal is to build a blockchain project that belongs to everyone

5. The allocation rule adopted by quark blockchain is pos (proof of stake), but most people probably don't understand what POS means, what are the advantages of quark using POS, and what is the conscience of quark blockchain projects compared with similar platforms
1. The distribution method of bitcoin is pow (proof of work), which means that if you want to get bitcoin, you have to calculate a mathematical problem with a large amount of calculation. Whoever calculates it first will be allocated the new bitcoin. POW mechanism has great advantages: good security, but there are also a variety of problems: huge energy consumption, low efficiency, the most important thing is that there is a monopoly of mining rights, without joining the mine pool, indivial miners can not dig bitcoin
2. This year's hottest EOS project adopts the dpos mode (entrusted POS), while EOS only allocates 5% of its share! The vast majority of EOS are distributed in the form of ICO (private placement), and the ETH obtained is used to support the development and maintenance of developers. In other projects, most tokens are distributed in the form of ICO, usually 20% of the shares are left to developers, and more than 50% of the shares are used for ICO, and the remaining share users can participate in the allocation
3. The POS mode adopted by quark blockchain is to freeze QKI (quark integral) to obtain computing power, and allocate the output by computing power, with 7200 points per day, 10% of them are allocated to the developer account, and the remaining 6480 points are distributed to each user according to the average computing power. The advantage of POS is that there is no threshold for mining, and everyone's output rate is the same. Take today's (June 19) data as an example: today's total computing power is 854447.792, and the output of each unit's frozen computing power is 0.007583845. For each user, the output is extremely fair
4. Our quark blockchain allocates 90% of its output to users
5. OTC transactions are free of handling charges, and quark blockchain is open, transparent and traceable.

6. Absolutely false, only the ll sound makes a lot of money, there is no publicity everywhere. At present, the propaganda is to ask you to accept the offer. You can see that bitcoin is the first currency in the blockchain. Currency is the right of a national bank, and bitcoin is too harmful. All countries and banks are resisting it. From the current trend, the disadvantages of blockchain currency outweigh the advantages, but blockchain technology is still promising, but not currency.

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

9.

Public chain is also known as "public chain", and public chain refers to the blockchain that anyone in the world can read and send transactions, and transactions can be effectively confirmed, and can also participate in the consensus process. According to the different degree of blockchain network centralization, three kinds of blockchain under different application scenarios are differentiated:

1. The blockchain with open whole network and no user authorization mechanism is called public chain

2. The authorized nodes are allowed to join the network, and the information can be viewed according to the authority. It is often used in the inter agency blockchain, which is called alliance chain or instry chain

3. All the nodes in the network are in the hands of one organization, which is called private chain

extended data:

function of public chain:

1. Public chain can protect users' rights and interests from the influence of program developers:

in public chain, program developers have no right to interfere with users, so public chain can protect users' rights and interests using the program. In addition, the highly decentralized distributed data storage is also one of the biggest characteristics of the public chain, which has the advantages of openness and transparency of transaction data, and data can not be tampered with, so that the public chain can effectively protect the data security of users

2. Public chain can proce network effect:

an information proct has the inherent need of interconnection, because the purpose of people procing and using them is to better collect and exchange information. With the expansion of the network scale, users can get more value from it and their needs can be met. The common chain is open, so it has the opportunity to be applied by many external users and proce a certain degree of network effect

3. Public chain can be applied to actual business scenarios:

except for financial applications, any application scenario with high requirements for trust, security and persistence, such as asset registration, voting, management and Internet of things, will be affected by public chain on a large scale
