Quark blockchain uses Ethereum

1.

what is Ethereum:

Ethereum is an innovation based on the application of technologies and concepts in bitcoin to computers. Ethereum itself imitates a lot of bitcoin technology to maintain the computer platform. blockchain technology is one of them
Ethereum platform can safely run any program users want

advantages of Ethereum over other competitive currencies before Ethereum appeared, some digital currencies imitated bitcoin. However, these projects have their own shortcomings, they can only support one or several specific applications at the same time< However, the reason why Ethereum can surpass the limitations of these projects in the past is because of the core idea of Ethereum

what Ethereum wants to implement is a blockchain protocol with built-in programming language. Since it supports programming language, in theory, any blockchain application can be defined with this language, and then run on Ethereum's blockchain protocol as an application

The design of Ethereum is very flexible and adaptable

Ethereum target sets the advantages of blockchain technology, in order to add the advantages of blockchain, such as decentralization, openness and security, to almost all computing fields

blockchain applications of Ethereum

Ethereum has many blockchain applications, such as digital applications of gold and stocks, financial derivatives applications, DNS and digital authentication, etc

Ethereum has achieved more than 100 blockchain applications by many start-ups

Ethereum has also been closely watched by some financial institutions, banking consortia (such as R3), as well as large companies like Samsung, Deloitte, RWE and IBM. As a result, a number of blockchain applications such as simplified and automated financial transactions, merchant loyalty index tracking, and gift cards designed to achieve decentralization of electronic transactions have emerged

the relationship between Ethereum and blockchain:

Ethereum is a programmable blockchain

Ethereum does not give users a series of preset operations (such as bitcoin transaction), but allows users to create complex operations according to their own wishes

in this way, Ethereum can be used as a platform for various types of decentralized blockchain applications, including but not limited to cryptocurrency

like other blockchains, Ethereum also has a peer-to-peer network protocol. Ethereum blockchain database is maintained and updated by many nodes connected to the network. Each network node runs the Ethereum simulator and executes the same instructions. Therefore, people sometimes call Ethereum "world computer"

2. Ethereum blockchain has exposed three major problems, and its founder vitalik buterin has been unable to interpret them for a long time. The first is the low performance and TPS of Ethereum blockchain as a whole; The second is that resources are not isolated. The event of cryptokitties virtual cat once occupied 20% of the traffic of the whole Ethereum, which directly caused Ethereum network users unable to carry out timely transactions, which is the biggest pain point of resources not isolated; The third problem lies in the embodiment of Ethereum's governance structure. As a decentralized distributed ledger, the founder team of Ethereum has dominated its network development in the past. The over centralized governance mode has led to the bifurcation of eth, etc and ETF in Ethereum, and the Ethereum community is now in a state of fragmented governance. In the view of Ma Haobo, founder and CEO of "aelf", all kinds of disadvantages of Ethereum are unacceptable. Therefore, the positioning of "aelf" is born for the next generation of decentralized underlying computing platform of Ethereum, which focuses on solving the problems of insufficient performance, non isolation of resources and governance structure of Ethereum.

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. Ethereum, ETH for short. At the end of 2013, vitalik released the white paper of Ethereum, and in July 2014, the pre-sale of Ethereum began. At that time, insiders called this kind of token issue "crowdfunding". Through the 42 day pre-sale, the Ethereum team raised more than 30000 bitcoins through the pre-sale of 60102216 Ethernet coins; In addition, the early contributors who participated in the development before the pre-sale and the developers who have been engaged in project research for a long time are allocated according to 9.9% of the total amount of Ethernet coins sold at that time. So when Ethereum was officially released, there were more than 72 million Ethereum coins. After the end of Ethereum's pre-sale, it uses the proof of work mechanism POW for mining, and rewards the miners according to 26% of the total amount issued at that time every year. In October 2014, Ethereum reced the block output time from 60 seconds to 12 seconds, and now it is basically stable at 15 seconds, with 5 etheric coins awarded for each block
although the pow mining mechanism is adopted, the block out mechanism of Ethereum is different from that of bitcoin. Due to the short block time of Ethereum, Ethereum is easy to form isolated blocks. Isolated blocks refer to the blocks that are not on the longest chain. Bitcoin's isolated blocks have no block rewards, but in Ethereum, isolated blocks can be referenced. The referenced isolated blocks are called "Uncle blocks", and their packaged data will also be recorded in the blockchain. Unlike bitcoin, Ethereum's TERT block has a reward, and each TERT block can get a reward of 4.375 Ethernet coins at most
Ethereum is a programmable and Turing complete blockchain development platform, which is equivalent to a decentralized global computer. In a programming system, there are usually some virtual machines to compile and execute. Java has JVM. In Ethereum, there is also Ethereum's virtual machine EVM, which can execute any complex algorithm code. Developers can use existing programming languages such as JavaScript or Python to create their own applications on Ethereum. Through Ethereum's virtual machine, you can easily issue digital assets, write smart contracts, set up and run decentralized applications, and set up decentralized autonomous organizations
eth is also known as the internal fuel of Ethereum. Unlike currency digital assets, Ethereum is not only used for transfer, but also for payment of smart contracts
in order to prevent the Ethereum blockchain from being full of junk contracts and junk applications, and to establish and run smart contracts on Ethereum, you must use eth to pay for smart contracts. For example, when you transfer your newly created digital assets on the Ethereum blockchain, you need to use eth to pay the handling fee instead of your newly created digital assets.

6. First, quark chain has a blockchain browser, which is a search tool for users to browse and query information on the blockchain
because of the openness and transparency of blockchain, it needs a medium that allows miners, regulators, developers, traders and other users to see the situation on the chain, such as a certain transaction, a certain block, and the current chain height
the blockchain browser is the medium. Here, we can see all the information on the chain. By entering a wallet address or a transaction ID, we can query the balance of the wallet and the details of any transaction
Second, quark chain trust has all PC nodes, all blockchain data can be saved on the computer, and each user can read or upload data. Of course, users who open PC nodes can gain certain prestige by "hanging up" for a certain period of time to proce more quark chain certificates CCT, which is an incentive reward for PC node users, At present, there are thousands of PC nodes in the world, and the number of nodes keeps growing
thirdly, quark chain trust has an open-source quark public chain (quark blockchain). Quark blockchain is an open-source public blockchain platform with smart contract function, with account model + gas mechanism, block time of 15 seconds, support Turing complete smart contract, and support Vyper solid language to write smart contract.

7. 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.

Blockchain 1.0 era usually refers to the development stage of blockchain application represented by bitcoin from 2009 to 2014. They are mainly committed to solving the problem of decentralization of currency and means of payment; After 2014, developers pay more and more attention to solve the technical and scalability problems of bitcoin. At the end of 2013, vitalik buterin released Ethereum white paper "Ethereum: next generation smart contract and decentralized application platform", which introced smart contract into blockchain and opened the application of blockchain outside the currency field, thus opening the era of blockchain 2.0< The so-called smart contract is actually a kind of computer contract that can be automatically executed based on prescribed trigger rules. It can also be regarded as a digital version of traditional contract. It was proposed by interdisciplinary legal scholar and cryptography researcher Nick Szabo more than 20 years ago. This technology was once not used in the actual instry because of the lack of programmable digital system and related technologies, until the emergence of blockchain technology and Ethereum provided a trusted execution environment for it

compared with bitcoin, Ethereum is a complete scripting language of Turing, which supports developers to create and publish arbitrary decentralized applications on the platform. Since its birth, there have been more than 200 decentralized applications based on Ethereum in the world

the chief researcher of bitwindow blockchain said: in the era of blockchain 2.0 represented by Ethereum, blockchain technology has graally expanded from the field of currency and payment to the field of finance. With the development of technology and the wider application of blockchain, the era of blockchain 3.0 beyond the monetary and financial fields will be around the corner. This article is excerpted from bitwindow. China's professional blockchain and digital currency instry analyzes the media, and adheres to a neutral, objective and dialectical attitude to understand and interpret the latest trends of blockchain and digital currency

9. 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.

10. 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.
