Member list of R3 blockchain Alliance

1. In the past two years, blockchain alliances have sprung up. What are their representatives
in the early stage of the development of the blockchain instry, many enterprises and institutions formed a blockchain alliance to share the research results of blockchain technology and seek wider application of blockchain technology
in the past two years, blockchain alliances have emerged. As of July 2017, there are R3 composed of more than 40 international banks, hyperledger initiated by Linux foundation, Zhongguancun blockchain Instry Alliance located in the core hinterland of China's Internet, China ledger alliance jointly initiated by 11 institutions, gold chain alliance jointly established by 25 financial institutions, and so on Russia's blockchain alliance, known as "Russian version R3", seeks to combine with micro finance, Qianhai international blockchain ecosphere alliance led by Shenzhen Qianhai administration, and Lujiazui blockchain Financial Development Alliance in Lujiazui
many organizations and talents join to promote the vigorous development of blockchain.

2. In China, there are two. China blockchain research alliance, Zhongguancun blockchain instry alliance, China distributed general ledger infrastructure agreement alliance, financial blockchain alliance, China Internet Finance Association blockchain research group, blockchain micro finance instry alliance, Qianhai international blockchain alliance, interbank market blockchain technology research group, Lujiazui blockchain financial development alliance, International Wenwan blockchain instry alliance. Currency exchange digital currency exchange

3. Blockchain is indeed very popular in China, but it's hard to say who is the boss in China. Because many domestic giant enterprises have begun to test the blockchain. For example, Wanda, the leader of the real estate market, ant financial services, the e-commerce market giant, Ping'an and Minsheng, the banking giant, LETV, the video website giant, and so on
in China, there are blockchain alliance organizations like R3, Ethereum, decent and other blockchain projects.

4. Blockchain mainly solves the trust and security problems of transactions, so it proposes four technological innovations to solve this problem:
(1) distributed ledger, that is, transaction bookkeeping is completed by multiple nodes distributed in different places, and each node records complete accounts, so they can participate in monitoring the legitimacy of transactions, At the same time, they can testify together
different from traditional distributed storage, the uniqueness of distributed storage of blockchain is mainly reflected in two aspects: one is that each node of blockchain stores complete data according to block chain structure, while traditional distributed storage generally stores data in multiple copies according to certain rules. Second, the storage of each node in the blockchain is independent and has the same status, which relies on the consensus mechanism to ensure the consistency of storage, while the traditional distributed storage generally synchronizes data from the central node to other backup nodes[ 8]
no single node can record the account data separately, so as to avoid the possibility that a single bookkeeper is controlled or bribed to record false accounts. In theory, unless all the nodes are destroyed, the accounts will not be lost, so as to ensure the security of the account data
(2) asymmetric encryption and authorization technology, the transaction information stored on the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy
(3) consensus mechanism is how to reach a consensus among all accounting nodes to determine the validity of a record, which is not only a means of identification, but also a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security
the consensus mechanism of blockchain has the characteristics of "the minority is subordinate to the majority" and "everyone is equal", in which "the minority is subordinate to the majority" does not completely refer to the number of nodes, but also can be the computing power, the number of shares or other characteristics that can be compared by computers“ "Everyone is equal" means that when the nodes meet the conditions, all nodes have the right to put forward the consensus results first, and then directly recognized by other nodes, and finally may become the final consensus results. Taking bitcoin as an example, the workload proof is adopted. Only when more than 51% of the accounting nodes in the whole network are controlled can a nonexistent record be forged. When there are enough nodes in the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
(4) smart contract, which is based on these trusted and tamperable data, can automatically execute some pre-defined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and reliable, it is easy to carry out automatic claim settlement in some standardized insurance procts

5. Yes, I've been in touch since 18 years, buying computing power and digging bitcoin on it

6. Yingchi Hall of fame is the top non-public graphics card. Although the time of silent frequency is similar to 1060, the ability of overclocking is much stronger than 1060. The official power consumption is 165W, while 1060 is 120W. After overclocking, the power consumption will be higher. Pay attention to whether the power supply is enough. The price of 900 yuan can be bought, but please note that if you play a stand-alone game, it may explode in some games. As for mining, so to speak, there is no ore card in the 9 series, and the N card mining was started on a large scale in the 10 series. It may have been before, but it's too few. Before the 10 series, they used to dig with a-card.

7. I used to go to my father Zhongshan on holiday because he rented a house and the balcony was public. In the room is too laggy to play, my father wants to work, I am afraid to disturb him, I went to the public balcony to play games, squatting there mosquitoes a little more, I simply climbed up the balcony (there is a security net). A man in his twenties came out to dry his clothes. It was 11:30 in the evening. When he asked me something, I casually answered him a few words, maybe because I speak better. His salty pig's hand touched my thigh and wanted to go in. I knocked off his hand at that time, but I was also very afraid, and my body was shaking all the time. I jumped off the balcony to get ready to go back. I didn't know that he pushed me in the corner to touch my chest and wanted to kiss me. I pushed him away and ran back to the room. Then I didn't dare to play games at night

8. Yes, Star Diamond technology is an important member of the blockchain alliance, which is still very influential
let's see what others say.

To put it simply, blockchain is a decentralized system, with & lt; Ledger & quot; For example, traditional & lt; Ledger & quot; It is controlled by the center, while the blockchain & lt; Ledger & quot; Without a center, everyone involved can be & lt; Ledger & quot; Record

blockchain generally refers to public blockchain, family members, private blockchain and instry blockchain{ Conclusion< p> Blockchain technology provides a fair platform for the public. Xiaobian believes that the application scope of blockchain technology will be wider and wider
