What are some successful blockchains
at present, the number of domestic blockchain related companies is increasing, among which fast online has always been in the leading position
up to now, we have independently developed 100 + Internet financial procts and provided innovative suggestions and solutions based on our years of instry experience and advantages
as the development platform of blockchain, she only focuses on the innovation of blockchain technology and proct development. There is an overall personalized solution from research and consultation, project start-up to the final system launch and later maintenance upgrade.
the people's Bank of China launched the trade finance blockchain platform: widely connecting the information of tax, customs, foreign exchange and other departments, effectively helping SMEs to increase their financing credit
State Grid supply chain financial data sharing platform based on data side chain: provide conditional and reliable sharing service of supply chain financial data under privacy protection, help small and medium-sized suppliers to revitalize accounts receivable, rece financing cost and increase financial income of financial institutions
there are also Guangzhou public law chain, blockchain e-invoice Express Edition, trade finance blockchain platform, blockchain deposit, blockchain traceability and so on. Cipher finance mimacaijing focuses on blockchain information.
(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

first of all, mining does not start from a trainer. Holding a hoe in hand, you can be a qualified miner. Patience, time and familiarity are essential to the distribution of minerals you need
-
there are many minerals in the roots of mountains, trees and grass - the minerals in world of Warcraft are mostly distributed at the foot of mountains, ridges, hillsides and the bulges of plains. If you want to mine more, fly more in those corners
-
the mines on each map have a fixed refresh time. If you plan to mine on one map for a long time, you can sell ah to other players who need it even if you don't need it
-
if you want to have high efficiency and try to enter the hole as little as possible, you are not recommended to enter the hole for one mine unless you see rare ore, rich XX ore or more than three ore spots in this hole on the gray ore spot of the small map
-
if it's the gathering instry, you will definitely meet competitors. When the plug-in shows that there are a large number of mineral spots on this map, and you haven't seen a mine for a long time, there must be a miner in the 1-2min flight distance in front of you. At this time, there are two options: first, go to other maps to proce the required minerals; second, try to fly backwards, He disrupted the rhythm of mining and the route of mineral refresh on the map
-
in the process of mining, we often encounter rare minerals that are not needed in the manufacturing list, such as gold and silver, krypton gold, Titan and so on, so we can mine them. A lot of gold can be sold
-
put one or two sets of hot flow anvil made by engineering in the bag. You don't need to run around to find the furnace or anvil. It's better if you have mop rare gloves of plunderers. If you want to go to the mining specialty, it's recommended to take F gloves that you don't need to collect, and take them with you when mining. Maybe you can help when it's critical< br />
that's too much... There are too many "e-businesses" with little investment and big profits
