AAA blockchain technology team
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.
From the perspective of technology and architecture, I will tell you my understanding of blockchain in common language
what is blockchain? In a word, blockchain is a storage system. To be more specific, blockchain is a distributed storage system without an administrator and each node has all the data
What are the common storage systems like
first, how to ensure high availability
the common storage system usually uses "rendancy" to solve the problem of high availability. As shown in the figure above, if the data can be copied into several copies and rendant to multiple places, high availability can be guaranteed. The data in one place is hung, and there is data in other places. For example, the master-slave cluster of MySQL is the same principle, and the raid of disk is also the same principle
two points need to be emphasized in this place are: data rendancy often leads to consistency problems
1. For example, in the master-slave cluster of MySQL, there is actually a delay in reading and writing, which means there is a inconsistency in reading and writing in a short period of time. This is a side effect of data rendancy
The second point is that data rendancy often reces the efficiency of writing, because data synchronization also consumes resources. If you add two slave libraries, the write efficiency will be affected. The common storage system is to use rendancy to ensure the high availability of dataso the second question, ordinary storage system, can write more
the answer is yes, for example, take this graph as an example:
in fact, MySQL can do a master-slave synchronization of al masters, master-slave synchronization of al masters, two nodes can be written at the same time. If you want to do a multi room multi live data center, in fact, multi room multi live data synchronization. What we should emphasize here is that multi-point writing often leads to the consistency problem of writing conflicts. Take MySQL as an example, suppose that the attribute of a table is self incrementing ID, then the data in the database is 1234 now. If one of the nodes writes and inserts a piece of data, it may become 5, and then these 5 pieces of data are synchronized to another master node, Before synchronization, if another write node inserts a piece of data, a piece of data with self incrementing ID of 5 will be generated. Then, after the generation, synchronize to another node, and the synchronized data will conflict with the two local 5's after it arrives, which will lead to synchronization failure and write consistency conflict. This problem will occur in the case of multi-point writing
how to ensure consistency in multi-point writing
the reform "Swan class" gives you more technical work
I sell it on 5173, but after it's sold out, its website will dect some money from you.
it seems that I dected 12 yuan for 120 yuan
forget.
it's an intermediary fee
On January 9, Zhou Wenzhong, Secretary General of Boao Forum for Asia, announced in Beijing that the Boao Forum for Asia annual conference 2017 will be held in Boao, Hainan Province from March 23 to 26, with the theme of "facing the future of globalization and free trade"
how to promote reform is also one of the key topics of 2017 annual meeting. Relevant topics include: supply side reform, labor market reform, health care reform, land system reform, fiscal and taxation system reform, financial instry green revolution, business transformation, ecation reform, the fourth instrial revolution, capital market and real estate market bubble, asset securitization, deleveraging, etc. p>
entrepreneurship, innovation and new economy are the new highlights of Boao Forum for Asia annual meeting in recent years. More than ten sub forums related to the new economy were arranged in this annual meeting, covering instrial design, urban personality, sharing economy, Silicon Valley innovation, artificial intelligence, virtual reality, big data, digital currency and blockchain, financial technology, entrepreneurship and capital, Internet automobile, direct broadcasting economy, etc
