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

3. 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.

4. There is nothing like what the landlord said. The quark team is good and the quark blockchain project is stable. Why are quark blockchains and teams trustworthy
first of all, quark blockchain has a group of young, enthusiastic and progressive team members, who can often interact with users in the communication group, collect their views on the project, answer various questions and discuss the future of the project. In addition, team members are familiar friends with each other, as well as with some of the participants online and offline. They often study and discuss problems face to face. Unlike some "written members" of project teams who only exist in the official website and the text introction of the white paper, in reality, the victims of some runaway projects simply don't know who the team members are? Where do you work? Let alone meet. Therefore, the choice of quark is to choose a safe environment with both the network world and the real world
secondly, in the development process of quark blockchain, team members, like ordinary participants, participate in the trading activities of QKI fairly, and the vast majority of team members buy a large number of QKI, which fully proves their absolute confidence in the project. Objectively speaking, the better the development of the project, the higher the income of each participant in the quark blockchain. Therefore, as the core part of the participants, team members have sufficient motivation to do well in the project
thirdly, from the perspective of technical support, quark blockchain has a block browser, all data are open and transparent, there is no falsity, and there is no possibility of falsification. The data that every participant can see can not be realized for the false project of making money and running away, which is also the best basis to show that quark blockchain is a real and reliable project
finally, the QKI purchased by each participant is from other users, and the point-to-point transaction ensures that the transaction funds will not flow into the team, and the participants do not have to worry about the risks brought by the so-called team's money circling problem.

5. 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.

6. Guizhou has released some standards, such as the quality model and key elements of blockchain system, the implementation process of data asset transaction of blockchain, the terminology and basic requirements of the implementation process of targeted poverty alleviation of blockchain, etc. now many local blockchain applications have been implemented. Our digital money package is also an application of blockchain technology, and now blockchain applications have been implemented one after another, Changsha high tech Zone has launched a SMIC blockchain service platform project, which is based on the blockchain + public service mode, and is soliciting enterprises to join the chain.

The term "smart contract" can be traced back to at least 1995 and was proposed by the prolific interdisciplinary legal scholar Nick Szabo. He mentioned the concept of smart contract in several articles published on his website. His definition is as follows:

"a smart contract is a set of promises defined in digital form, including the agreements on which the contract participants can implement these commitments."

Let's explore the meaning of his definition in more detail

commitment

a set of commitments refers to the (often mutual) rights and obligations agreed by contract participants. These commitments define the nature and purpose of the contract. Take a sales contract as a typical example. The seller promises to deliver the goods and the buyer promises to pay a reasonable price

digital form

digital form means that contracts have to be written into computer-readable code. This is necessary, because as long as the participants reach an agreement, the rights and obligations of smart contract establishment are executed by a computer or computer network

(1) when will the parties to the smart contract reach an agreement? The answer depends on the specific smart contract implementation. Generally speaking, the contract is discovered when the parties are committed to the execution of the contract by installing the contract on the contract host platform

(2) the real meaning of "execution" also depends on implementation. Generally speaking, implementation means active implementation through technical means

(3) computer readable code

in addition, the specific "digital form" required by the contract is very dependent on the agreement that the parties agree to use

protocol

protocol is technical implementation, on this basis, the contract commitment is realized, or the contract commitment is recorded. Which agreement to choose depends on many factors, the most important of which is the nature of the assets being traded ring the performance of the contract

again, take the sales contract as an example. Suppose that the participants agree to pay in bitcoin. The chosen protocol will obviously be bitcoin protocol, on which the smart contract will be implemented. Therefore, the "digital form" that the contract must use is bitcoin scripting language. Bitcoin scripting language is a non Turing complete, imperative, stack based programming language, similar to forth

smart contract

the Xueshuo innovation blockchain Technology Workstation of Lianqiao ecation online is the only approved" blockchain technology professional "pilot workstation of" smart learning workshop 2020 Xueshuo innovation workstation "launched by the school planning, construction and Development Center of the Ministry of ecation of China.
