What is equivalent to Sequoia Capital in the blockchain
in China, the other one I know is the network mutual aid blockchain, which represents the platform of concentric mutual aid. Blockchain technology is used to solve the shortcomings of the network mutual aid instry. At present, blockchain is also very popular in the network mutual aid instry.
"Malaysia's biggest liar" Zhang Yufa cheated the Chinese 500 billion yuan in a few years, making the "capital plate", "rebate plate" and "air currency" perfect.
Blockchain is the general trend of the tuyere project, but when choosing blockchain projects, we must shine our eyes and find a team with technology, application and real down-to-earth work. Otherwise, it may come to nothing, because since it is a trend, naturally there are a lot of speculation and fraud projects
here, we mainly introce utispace, the first blockchain distributed storage project with perfect technology and real application in the world
investment highlights
a brief introction to utispace: is 5g coming? Have big data, artificial intelligence, wearable devices, Internet of things and AI entered our lives? Is the phone running out of memory
stuck
the high-speed information flow inevitably needs infinite storage space, but the current storage space is never enough
for example, the storage space of 4G mobile phone determines the price of mobile phone, but what about 5g mobile phone? More to 10 times the demand for 4G space storage, the price will be expensive
where there is demand, there is market. In the past, we need to build a big data storage base station for big data storage. The cost is very high. It costs 10 billion yuan at any time, and the security is very low (the base station will be hot and prone to fire and earthquake, what should we do? If hackers attack all data, they will be paralyzed). In addition, no matter how big the base station is, its storage capacity is limited, and it can never meet the demand of doubling the amount of data generated by the market, resulting in a large number of useful data homeless. At present, 67% of the data has been deleted, which is a great loss
so who can solve the data storage with large storage, high security, low cost and low energy consumption
today, the decentralized distributed storage space of China's own brand utispace, together with the digital pulse chain Laboratory of Zhejiang University, has solved this worldwide problem. Thus, it takes the lead in occupying the big cake of distributed data storage
it's estimated that the virtual currency that ordinary people can't afford is not easy to make, so don't think about it any more.
most digital cryptocurrencies claim to be a third-party payment instrument. Although they are also feasible in theory, the actual situation is just the opposite. The payment using digital cryptocurrency is very little, and the most used one is still bitcoin, and the others basically do not exist. If it exists, it's just hyping this kind of currency. Now, the application-oriented digital currency basically does not mention payment. For example, Ruitai coin refers to asset mortgage, and Weimeng coin refers to service wechat business.
blockchain is the big ledger of bitcoin network, and each block is equivalent to a page in the ledger. What information is recorded in the "account book"? At present, each block of bitcoin mainly records data such as block head, transaction details, transaction counter and block size
"block header" contains all information except transaction information, mainly including the hash value of the previous block header, which is used to ensure that blocks are connected in sequence; Time stamp: record the generation time of the block; Random number: that is, the answer to the arithmetic problem of PK for all miners in the whole network; Difficulty target: score the difficulty coefficient of the arithmetic problem
"transaction details" records in detail the transferor, income party, amount and digital signature of the transferor of each transaction, which is the main content of each block
"transaction counter" describes the number of transactions contained in each block
"block size" refers to the size of each block data. Currently, each block is limited to 1MB, which does not rule out the possibility of expansion in the future.
