Forum based on blockchain Technology

1.

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 data

so 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

2. There are two ways, one is to know the technology, according to the application you want to develop to determine the technical points to be used, and then to develop. Second, we don't know the technology, we still need to determine the requirements, and then we may go to the blockchain system template or blockchain application template, or such developers for consultation

3. Different communities belong to community assets, and forums belong to different local attributes of communication

4. At present, the domestic blockchain is more professional, which is a pure blockchain technology Q & a community launched by wanglian technology, aiming to provide business for blockchain technology lovers
this is a gathering place for blockchain enthusiasts, with tens of thousands of blockchain practitioners and many top experts in the instry. Blockchain brothers are not only a platform for technical exchanges and answers to difficult and miscellaneous problems, but also innovative incentives and project training to drive the talent cultivation and development of the blockchain instry, and continue to provide rich instry resources to truly serve blockchain talents.

5. Which one is good for this blockchain forum? I am engaged in the blockchain instry. Over the years, I have found that there are few blockchain forums

firstly, the development of blockchain is still at an early stage; secondly, the uncertainty in the blockchain instry is manifested in the aspects of supervision and so on. Although many institutions of the national government are committed to the establishment of blockchain instry standards, blockchain as a new thing, to formulate relevant laws and regulations, still need to be discussed and studied by many parties

when it comes to blockchain forums, there are Babbitt, blockchain home, coin world, Zhiqu chain and so on. Blockchain forum which is good, you need to practice more, after all, everyone has different views. I hope the above content can help you.

6. This should not have been done yet. It's a waste that blockchain is used to make forums and websites

7.

Good mobile game trading platforms are:

NO.4: Netease buff

Netease buff is a trading platform launched by Netease company to support steam game accessories, aiming to provide players with a more real-time, safer and more convenient game accessories trading market environment

8. The people's Congress should formulate relevant laws and regulations to protect blockchain technology and use it to govern the country< The party should strengthen its leadership. Improve the party's ruling ability and govern scientifically. Using blockchain technology to govern the country

the government administers according to law and makes decisions scientifically and democratically. Perform related functions, and carry out network politics and other activities
please take it.

9. Now there are not a few people learning blockchain technology, but there are not many blockchain training institutions. There are many Internet blockchain communities and blockchain platforms, such as Babbitt, Zhiqu chain, Golden Finance and other platforms, in which the information, knowledge and experience, videos, blockchain project cases, etc. of the blockchain instry can be bought. Combined with the above-mentioned blockchain platforms, I can learn, summarize experience and practice, After a period of time, we will have a new understanding of blockchain technology.

10. The analysis of jinwowo network is as follows:
as the most advanced underlying technology of the Internet, the development of blockchain will subvert and reshape human social relations, and innovate to promote the change of business model
everyone is eager to understand the latest policy trend of this advanced technology, the compliance in the application process, the symbiotic and complementary relationship with big data, and the future commercial application channels, because all these are the foundation of social development in the future digital economy era.
