Research status of blockchain

1. blockchain is the biggest trend in the next decade
if you look at the problem with the thinking of 30 years ago, you will think that others are crazy, but in fact you are out of date
the concept of blockchain can be traced back to the end of 2008. In the forum, a mysterious personage named "Nakamoto Tsung" published a paper "bitcoin: a peer-to-peer e-cash system" and proposed the concept of blockchain for the first time
on January 3, 2009, the first block of the blockchain was born, which is called the "Founding block"
almost with the birth of blockchain technology, bitcoin became the first thing to play its role. In the following years, bitcoin graally swept the world. In 2017, its crazy market made blockchain technology known to all
the idea of blockchain first appeared in the famous bitcoin open source project. In the process of its birth and development, bitcoin project draws on the technical achievements from digital currency, cryptography, game theory, distributed system, cybernetics and other fields. It can be said that bitcoin project is good at all. As its core supporting structure, blockchain technology is a remarkable innovation achievement
blockchain is a distributed database system with different nodes, which is an open ledger system<
three characteristics of blockchain
compared with the traditional centralized scheme, blockchain technology mainly has the following three characteristics:
the core idea of blockchain is decentralization
in the blockchain system, the rights and obligations between any node are equal, and all nodes have the ability to vote with computing power, Thus, the result recognized by more than half of the nodes is guaranteed. Even under serious hacker attacks, as long as the number of nodes controlled by hackers does not exceed half of the total number of nodes in the world, the system can still operate normally and the data will not be tampered with
block chain's biggest subversive is the establishment of credit
the collective maintenance of blockchain can rece the cost
in the centralized network system, the maintenance and operation of the system depend on the operation and operation of platforms such as data center, and the cost cannot be omitted. Anyone can participate in the nodes of the blockchain. Each node can verify the correctness of the results of other nodes' records while participating in the records, which improves the maintenance efficiency and reces the cost
in a word, blockchain touches money, trust and power, which are the fundamental basis for human survival< Its development has gone through three stages
1. Brewing period: from 2009 to 2012, bitcoin and its instrial ecology are the main economic forms
2. Embryonic period: from 2012 to 2015, with bitcoin entering the public view, new wallet payment and remittance companies appeared, and blockchain economy spread to the financial field. The underlying technology of blockchain is constantly innovated. Blockchain technology is separated from bitcoin system
3. Development period: in 2016, we began to explore instry applications, and a large number of blockchain start-ups appeared. The popularity of ICO in 2017 has given blockchain unprecedented attention
"blockchain 2.0 era" is coming
the application service layer is the driving force for the sustainable development of blockchain, which is divided into three stages of application: 1.0, 2.0 and 3.0
programmable currency: blockchain 1.0 application
programmable currency is the digital currency represented by bitcoin, but it is not the legal tender of any country or region, and there is no government authority to provide guarantee for it
programmable Finance: blockchain 2.0 application& quot; Smart contract& quot; Using program algorithm to replace the concept of contract execution. This enables blockchain to expand from the original monetary system to the registration and transfer of equity, creditor's rights and property rights, the transaction and execution of securities and financial contracts, and even the financial fields of gambling and anti-counterfeiting
programmable Society: blockchain 3.0 application
blockchain is the core of value Internet, which can confirm, measure and store the property rights of information and bytes representing value in each Internet. It can not only record the transactions of the financial instry, but also record almost anything valuable that can be expressed in the form of code. Its application can be extended to any field with demand, and then to the whole society
at present, the application of blockchain has begun to surpass bitcoin (blockchain 1.0), enter the era of blockchain 1.5, and transition to the financial field (blockchain 2.0)
in the next 3-5 years, blockchain may go beyond the financial field and enter the field of social notarization and intelligence (blockchain 3.0), including identity authentication, notarization, arbitration, audit, domain name, logistics, medical care, mail, visa, voting and other fields. Its application scope will be expanded to the whole society, and blockchain technology is likely to become a new technology& quot; All things are connected& quot; It's the lowest level protocol
at present, blockchain technology has been recognized by the world, and its development has become an inevitable trend. Accompanied by more people's attention, "in the next 30 years, new technologies will be integrated into all aspects of traditional instries, and human society will turn upside down. No matter who you are, no matter where you are, all of us will be a part of this great change."
this is the current situation. Blockchain has given the post-90s an opportunity. However, if you want to control blockchain technology without being affected by negative factors, the most important thing is to have a clear understanding of it, whether it is regulators, researchers, speculators or bystanders
it's time to devote more energy to blockchain technology
in China, the average annual salary of blockchain positions has reached more than 300000, and that of some enterprises has reached more than 1 million. The monthly salary of blockchain instry graates in Beijing, Shanghai and other places has exceeded 20K! If the post-90s seize the bonus of the times, they may become the next Alibaba in the future! If you miss it, you may regret it for ten years.

2. Since blockchain will become the future development trend, blockchain technology has its own advantages over traditional technology
1. Decentralization
the core advantage of blockchain technology is that it does not need a traditional centralized organization, and does not rely on the point-to-point transaction, coordination and cooperation of a credit center in the distributed system, so as to avoid the common problems of data security, collaborative efficiency and risk control of centralized organizations
2. High security
in blockchain technology, data is difficult to tamper with. Anyone can access the database that records transactions. In this transparent and open mode, everyone can act as a supervisor. We can see at a glance what changes have taken place in the data, which is more secure than traditional technology
3. More reliable
the blockchain technology is connected by multiple nodes in different places. The nodes in the blockchain interact through the point-to-point communication protocol. Under the condition of ensuring the consistency of the communication protocol, different nodes can be processed by different developers using different programming languages and different versions of the whole node
in short, when a node encounters network problems, hardware failures, software errors or is controlled by hackers, the operation of other participating nodes and systems will not be affected
therefore, blockchain is more reliable than traditional technology
therefore, I firmly believe that the application of blockchain must be the development trend in the future.

3. 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.

4. The ways to obtain bitcoin are as follows:
as a payment method for goods or services
buy bitcoin on a bitcoin exchange
exchange bitcoin with people near you
earn bitcoin through competitive mining
participate in the platform and get a gift from the platform.

5.

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
