Research trends of blockchain at home and abroad

1. Professor Hu Kai's research mainly includes:
digital economy and blockchain Technology: he is one of the earliest scholars engaged in blockchain technology in China. He has proposed and developed such theoretical methods as smart contract engineering (SCE), legal code technology, verification as a service (VAAs), etc. in the fields of combination of digital economy and blockchain, planning and consulting of digital economic Park, digital governance of blockchain, and so on Blockchain scalability, Multi Chain interconnection and blockchain formal verification technology have in-depth research and patent achievements. He presided over the research and development of Beihang blockchain series procts, including various forms of blockchain systems with independent intellectual property rights, browsers, monitors, deployment tools and blockchain big data management system (opendata)
distributed parallel computing and network: he has been engaged in cluster computing system, high-performance computing, aerospace electronic bus, and integrated network information technology research in complex computing environment for a long time. He proposed and studied the theory of reconfigurable multi cluster computing based on wolf pack and applied it to practice, and developed several application software systems
formal design and verification methods: in close cooperation with irit and INRIA, we have established a Sino French joint research laboratory for formal methods, studied model driven formal design and verification methods, proposed a number of innovative extension technologies based on AADL and synchronous language signal, and developed a number of model transformation, model validation and verification methods Verification and automatic code generation tools
in recent years, he has published more than 60 papers on SCI / EI retrieval in important academic journals at home and abroad, edited new technologies of network computing (416 pages, published by Science Press in 2001), and cooperatively completed the national authoritative textbook introction to distributed computing system (490 pages, published by Tsinghua University Press in 2014), which won the first prize of 2016 textbook, It has been adopted by more than ten key universities. He has successively presided over and participated in a number of National Natural Science Fund, national key R & D projects, 863 major projects, Junkou 863 project, National Nuclear high-tech foundation project, aerospace fund, and a number of important engineering projects in aerospace field. He won more than 30 national invention patents and soft works, won the five-year achievement award of aviation fund in 2015, and won the second-class innovation achievement award of Instry University Research Institute in 2018.

2. Theoretically, the block reward that can be generated every day is zd12.5 (number of rewards per block) * 6 * 24 (6 blocks per hour, 24 hours per day) = 1800btc. bitcoin network gives out one block every 10 minutes on average, and the reward for each block is currently 12.5. At the earliest time, 50 BTCs were awarded to each block within the block. After 210000 blocks were g out, the number of BTCs was halved, about once every four years. It is expected that the next halving will be in May this year, when the reward for each block will become 6.25. There is a special exchange for buying bitcoin. It is suggested to go to okex exchange in China. The security is great.

In 2014, Barry Silbert, founder of secondmarket, separated the bitcoin investment fund from the original company and established grayscale investments

in 2015, gray investment company was merged into the newly established digital currency group (DCG). DCG is not only focused on digital currency and blockchain investment, but also an incubator for start-ups. In addition to gray investment company, DCG also has two subsidiaries, namely, genesis, a cryptocurrency OTC broker, coindesk, a blockchain news and information website, and more than 150 other blockchain companies / projects invested

after years of development, gray investment company has become the largest cryptocurrency asset management company in the world, and its cryptocurrency trust scale has reached US $2.58 billion

{rrrrrrr}

extended information:

in 2013, Barry Silbert, the founder, convinced the board of directors of secondmarket company to set up a bitcoin investment fund called bitcoin investment trust, which is the predecessor of gray scale bitcoin trust. It was not until September 2017 that gray investment's bitcoin trust fund began to grow explosively

it has become the largest bitcoin investment trust in the world, with more than 408500 bitcoins, nearly 2% of the total. In addition to bitcoin trust funds, gray investment company also launched BCH, ETH, etc, horizon, LTC, XLM, XRP and Zec trust funds, as well as grayscale digital large capital fund with mainstream currencies. Gray investment company's cryptocurrency trust procts provide convenience for institutional users to purchase cryptocurrency

4. Bitcoin plate is big, equivalent to the stock market, I think it is not suitable for novices. virtual currency is still worth playing now. For example, the flow of virtual currency is relatively small, which is more suitable for people who are not willing to save and who are not willing to take too much risk.

5. It seemed ill bred, completely devoid of the superiority that Mr. Heathcliff and his wife could see. he
