The fastest blockchain

1. Now there are two kinds of miners. One is to directly choose the mining machine with high income. For example, the income of the A9 is very considerable. It can earn about 620 watts a day, and the power consumption is not high. In this way, if the miner wants to start, it should be done as soon as possible. Only in the previous period can it achieve low cost and high benefit. There will be no such situation when the later period is stable. 2、 The miner doesn't have to pay attention to the current currency income. He only cares about the currency, waiting for him to turn over.

2. 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

3. I mean the price. The price is proportional to the calculation power. The higher the computing power is, the higher the probability is. It is predicted that the current valuation is too low. Many miners are mobilizing their computing power to join in. I was optimistic a while ago, and it is not surprising. In this way, mining can survive for a while. Yes, rising means more computing power will come in. See more answers & gt& gt;

4. This is generally to okex, which is relatively large in China. The real-time market view and transaction operation are also simple.

6. In essence, blockchain is a decentralized distributed ledger database and the underlying technology of bitcoin and other "virtual currencies". Buyers and sellers can trade directly without any intermediary. Four technologies launch future cloud nodes to build the largest blockchain Storage Cloud node in China

7. It's Xunlei. Many years ago, Xunlei transformed the blockchain. Because of its first mover advantage, Xunlei has obtained world-leading technological achievements. The emergence of blockchain makes Xunlei find its "right way to open". In such a hot situation of domestic blockchain, I think Xunlei can take the lead. Xunlei has been technology-oriented for many years, forming technology precipitation, and blockchain technology has a strong natural correlation with P2P technology and distributed technology of shared computing on which Xunlei started, so Xunlei can rise rapidly in this field. According to the current momentum, as the blockchain instry environment develops step by step, we believe that Xunlei's technical advantages will usher in more opportunities for transformation and embodiment, and enter a new development cycle.

8. The blockchain proct of four technologies is a kind of virtual currency, which can be used as the material of currency. It mainly evolved from proct exchange to metal currency to paper currency, and then to today's digital currency.

9. I think blockchain models are very profitable, because I think blockchain is a popular development model.
