Yangtze River Delta plus block chain
Publish: 2021-04-25 03:44:08
1. 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

the margin ratio and handling charge are stipulated by the exchange, but different companies add different amount on the exchange
our company adds the least amount: if the margin is not added, the handling charge is only 0.01 0.01
5. I've noted that the overall response of Shenma mining machine is good. If you need to mine, you can pay attention to it.
6. Joining the blockchain is an inevitable choice to comply with the trend of the times, so we have to mention the water quantum community. In short, the water quantum community is a super node of the exchange based on the blockchain technology, which is equivalent to the securities company of the exchange. You can choose to join the water quantum community to become the super node partner of the exchange, so as to further contact the blockchain. As a partner of the super node, it has the following advantages: holding the token of the exchange, enjoying the Commission dividend, the sponsor of the digital assets on the exchange, paying dividends on the currency fee, etc., and the exchange will give corresponding rewards to the super node ranking first every month.
7. I can tell you for sure, of course! As a special pride of the people of Jiangsu and Zhejiang, the implementation of this policy has indeed benefited many of our local people. Now it only needs a "drop" to realize the automatic second level settlement of Metro cross city transactions, even when the signal is poor. In addition to the technical features of ant chain that can not be tampered with, real-time link up and so on, which can automatically settle settlement in seconds across cities, Alibaba cloud EMAS platform solves the problem of compatibility between mobile phones and gateways, In addition, the multi-faceted technological breakthrough of MAPAS one-stop cloud solution has brought people such a convenient life and greatly praised Alibaba blockchain.
