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.

2.
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.

7. Beck chain uses two ways to effectively fight against centralization and prevent joint evils among nodes:
first, expand the scope of integrity candidate nodes to 5% of all nodes, and randomly select consensus and accounting nodes from the candidate pool according to the time task. The larger the scope of nodes involved in the consensus, the less likely it is to commit joint crimes< Second, select nodes based on bit-r reputation value. Bit-r reputation value is the behavior portrait and historical transaction record of each user and node, which cannot be merged and transferred like token, so the feasibility of joint evil between nodes is small.

8. There are three ways to speed up the opening speed of web pages: one is to improve the network bandwidth, the other is to optimize the user's web pages on the local computer, and the third is to optimize the web pages by web site designers
here are some processing methods:
optimize the image and use the appropriate image format
optimize CSS
rece HTTP requests (remove some unnecessary objects, combine two adjacent pictures into one, merge CSS)
remove unnecessary add ins
make some content static when it can be static, so as to rece the burden of the server
put the statistical code at the end of the page
