Bitcoin chain
bitcoin is equivalent to digital gold. As a generally recognized equivalent, gold naturally has monetary properties and has been regarded as a kind of currency since ancient times. Bitcoin was born in 2009 and created by a person named Nakamoto. As the earliest digital currency, it was worthless at the beginning of creation. Until 2017, the highest transaction price of bitcoin exceeded 30000 RMB. The reasons why bitcoin became a valuable digital currency are as follows:
first of all, it is like gold, as a natural mineral, The total amount of bitcoin is limited. Bitcoin can not be over issued according to its own algorithm, so there will be no rapid devaluation of currency e to excessive currency issuance. The number of bitcoin is controlled to no more than 21 million e to the algorithm, so it can not be issued in large quantities, so its value is guaranteed
blockchain is a general technology derived from bitcoin. It implements a decentralized database model. Bitcoin can be called blockchain 1.0 because it has no concept of smart contract. The key technologies of blockchain include cryptography encryption and decryption and consensus mechanism. Blockchain is generally used to combine with specific business logic, which needs to rely on smart contract, which provides an execution mode free from human interference
the IPO of ICO originates from the concept of initial public offering (IPO) in the stock market. It is the behavior of blockchain project to issue token for the first time, raise bitcoin and solve Ethereum and other common digital currencies.
blockchain technology is the underlying technology of bitcoin, and bitcoin is the first application of blockchain. As mentioned earlier, the transaction information of bitcoin is recorded in a decentralized ledger, which is called blockchain
if we compare the blockchain to a physical account book, then each block is equivalent to a page in the account book. A new account book is generated every 10 minutes, and the transaction information of bitcoin network is recorded on each page. According to the principle of cryptography, each block is connected in chronological order to form a chain structure, so it is named blockchain
since the white paper "bitcoin: a peer-to-peer e-cash system" was born, major financial institutions at home and abroad have been competing to study the underlying technology of bitcoin blockchain and seek the practical application of blockchain technology.
The crazy speculation of the blockchain concept in the A-share market has quickly aroused the attention of the regulatory authorities. The Shanghai Stock Exchange said that the "blockchain" technology is still in the development stage, it is difficult to form stable business, and there are obvious signs of concept speculation
on the other hand, some companies are suspected of taking the initiative to "post hot spots" and releasing their own business scope involving blockchain, typically youjiu game and Shangying global. In this regard, after the Shanghai Stock Exchange monitored the company's relevant remarks, it took an emergency morning suspension of trading in the company's shares, and issued a letter of inquiry to the company, asking the company to explain in detail whether it catered to the hot spots in the market, whether the relevant behaviors were in violation of regulations, and fully remind the company of the risks. At the same time, check insider trading. After the two companies recovered and resumed trading, one stock price fell to the limit, and the other was close to the limit. It is reported that the Shanghai Stock Exchange will also take disciplinary measures against the company's suspected violations
