Coin circle and blockchain
blockchain technology is not only the underlying technology of bitcoin, but also the core and infrastructure of bitcoin bitcoin has been running without any centralized organization operation and management. Later, bitcoin technology was abstracted, which was called blockchain technology or distributed ledger technology
extended data:
disadvantages of blockchain technology applied to digital currency:
first, there is no circulation management organization for "decentralization" blockchain technology is essentially a distributed database system with one-way linked list logic structure and P2P network design mode, which determines that there is no unified central control system for virtual currency based on blockchain technology
Second, it is difficult to effectively control the quantity supply the circulation of virtual currency based on blockchain technology is fixed, and according to Fisher Equation, the total transaction volume of the whole society under a certain price level in a certain period has a certain proportion with the required nominal currency volume, while the constant currency volume obviously can not meet the requirements of the growing total price of social goods Thirdly, "mining mechanism" is difficult to create recognized value bitcoin itself has no value and no national credit support. Some people think that "by continuously consuming computing power and energy to inject value into virtual currency", but it is obviously not the most efficient choice to consume millions of calculations in order to find a hash value that meets the requirements Fourthly, procers and early holders are easy to get high seigniorage any virtual currency based on blockchain technology is held by a few people at the initial stage of its development. Take bitcoin as an example. At first, bitcoin was only a proct of a few people's game. The first bitcoin purchase in May 2010 was $10000 BTC's purchase of $25 pizza. The first bitcoin transaction completed in July of the same year was $0.04/btcin recent two years, there has been a digital currency craze in the investment field. Some people invest their spare money in bitcoin, Ethereum and other virtual digital currencies and hold them for a long time these people go for the purpose of getting rich. The prices of digital currencies such as bitcoin and Ethereum are like a roller coaster, sometimes rising and sometimes falling. Some people can't hold on to early selling in this storm, and some miners with a high degree of consensus insist on keeping their currencies and are unwilling to sell their digital currencies at a low ebb. Over the past year, this persistence has paid off. Now bitcoin is going to exceed $50000, which has soared many times{ RRRRR}
the world's richest man also invests in bitcoin. It seems that bitcoin will have more good prospects. the capital market is unpredictable, and the future of bitcoin will attract more people's attention
There have been blockchain projects launched, such as utispace. Blockchain is the general trend of the tuyere project, but in the selection of blockchain projects, we must shine our eyes, we must find a team with technology, application landing 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
give a brief introction to utispace: is 5g here? 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
Themis public chain is the first decentralized digital asset custody public chain based on blockchain technology
Themis provides third party trusteeship services (similar to the role of Alipay and PayPal in online shopping), issuing tokens global trust token Global Escrow Token (GET) on the chain, Themis introces the group trust mechanism and reputation mechanism based on economic incentives to encourage block chain nodes, using escrow contracts and arbitration contracts to achieve digital money between them. Fair exchange between digital currency and real assets. Through the payment of custody fees and arbitration service fees, it can provide incentives for the nodes to actively participate in fund custody and dispute arbitration. In the process of using digital currency payment, users need to pay get token to get hosting and arbitration services. Participating in the trusteeship and arbitration node, after the transaction is completed, you can get the service charge and reward of get token from the trading party, so as to realize the closed-loop flow of get token on Themis
