The concept of blockchain super node

1. Nodes are the places where the blocks are connected, and the blocks need to be chained to be useful
core analysis:
1. Transparency, 2. Openness, 3. Information can not be tampered with, 4. Decentralization,
5. Detailed analysis
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
1. In a narrow sense, blockchain is a kind of chained data structure composed of data blocks connected in sequence according to the time sequence, and it can not be tampered with and forged by cryptography
2. Broadly speaking, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing method to program and operate data by using intelligent contract composed of automated script code.

2.

Blockchain is a new application mode of distributed data storage, which is an important concept of bitcoin. At present, there are 35 stocks associated with the blockchain concept in the A-share market, of which 6 blockchain concept listed companies are traded on the Shanghai Stock Exchange, and 29 blockchain concept listed companies are traded on the Shenzhen Stock Exchange

according to the correlation of blockchain, the leading stocks of blockchain concept stocks are most likely to be born from Xinchen technology, luyitong and Sifang Jingchuang

Xinchen Technology: on September 29, 2016, the company said in the interaction that the company is now doing research and development of blockchain technology

Lu Yitong: the company plans to raise 67.9691 million shares of additional shares of RMB 24.57 per share, and the total amount of supporting funds will not exceed RMB 1.670 billion, which will be used to pay the cash consideration of this transaction, construct the block chain ASIC chip instrialization project, artificial intelligence ASIC chip R & D center, chip proct marketing and service network, etc

Sifang Jingchuang: on May 31, 2016, the inaugural meeting and the first general meeting of the financial blockchain cooperation alliance (Shenzhen) was officially held in Shenzhen Wuzhou Hotel, and the company was one of the members of the meeting

3. In short, it is an important concept of bitcoin

4. Bitcoin market suddenly soared, and now you can buy it. But you have to buy by yourself. Think about it, because bitcoin is a virtual currency. Market uncertainty, buy carefully.

5. The super node is online 24 hours a day, and anyone's account book will be updated to the general ledger through blockchain technology.

6. The main responsibilities of super nodes are as follows:
1. Provide server nodes to ensure the normal operation of nodes
2
3. Verify transactions and package them into blocks
4. Broadcast blocks to other blocks and add them to your local blockchain after verification
5. Guarantee and promote the development of blockchain projects
it can be seen that the super node determines the stability of the whole ecosystem of EOS
based on the main responsibilities of the super node, all its computing power needs to be provided by itself. According to the hardware threshold announced by the EOS team, first of all, it needs to reach at least Amazon AWSEC 2 host x1.32x large, 128 core processor, 2TB memory, 2x1920gb SSD and 25gb bandwidth. The cost of a single server is as high as 700000 yuan a year
when the DAPP based on EOS goes online, the cost of network bandwidth will also rise e to the increase of transaction volume, which requires a strong economic foundation and professional technical strength to participate in the election.
