58 blockchain
blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
blockchain money making methods:
1. Promotion to earn commission
the method of blockchain is to first register the exchange account, generate your own invitation link, and then promote it. If someone registers the exchange through your link and generates a transaction, you will have a commission
2
currency speculation is like stock speculation. Currency speculation is the lowest threshold for blockchain to make money
3. mining
Mining in bitcoin is the process of bookkeeping. This process needs to be tackled. If you seize the opportunity of bookkeeping right, there will be a reward. The reward is bitcoin. This behavior is called "mining"
4
wallet is the infrastructure of the block chain, just like the "Alipay" or "WeChat payment" of the block chain. p>
development materials:
1. Blockchain is an important concept of bitcoin, which is essentially a decentralized database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
2. The blockchain was born from the bitcoin of Nakamoto Tsung. Since 2009, there have been various digital currencies similar to the bitcoin, which are all based on the public blockchain
On January 20, 2016, the digital currency seminar of the people's Bank of China announced that the research on digital currency has achieved phased results. The meeting affirmed the value of digital currency in recing the issuance of traditional currency, and indicated that the central bank was exploring the issue of digital currency. The expression of the digital currency seminar of the people's Bank of China has greatly enhanced the confidence of the digital currency instry. This is the first time that the five ministries and commissions of the people's Bank of China have expressed a clear attitude towards digital currency since they issued a notice on preventing bitcoin risks on December 5, 2013 blockchain network
(1) distributed ledger, that is, transaction bookkeeping is completed by multiple nodes distributed in different places, and each node records complete accounts, so they can participate in monitoring the legitimacy of transactions, At the same time, they can testify together
different from traditional distributed storage, the uniqueness of distributed storage of blockchain is mainly reflected in two aspects: one is that each node of blockchain stores complete data according to block chain structure, while traditional distributed storage generally stores data in multiple copies according to certain rules. Second, the storage of each node in the blockchain is independent and has the same status, which relies on the consensus mechanism to ensure the consistency of storage, while the traditional distributed storage generally synchronizes data from the central node to other backup nodes[ 8]
no single node can record the account data separately, so as to avoid the possibility that a single bookkeeper is controlled or bribed to record false accounts. In theory, unless all the nodes are destroyed, the accounts will not be lost, so as to ensure the security of the account data
(2) asymmetric encryption and authorization technology, the transaction information stored on the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy
(3) consensus mechanism is how to reach a consensus among all accounting nodes to determine the validity of a record, which is not only a means of identification, but also a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security
the consensus mechanism of blockchain has the characteristics of "the minority is subordinate to the majority" and "everyone is equal", in which "the minority is subordinate to the majority" does not completely refer to the number of nodes, but also can be the computing power, the number of shares or other characteristics that can be compared by computers“ "Everyone is equal" means that when the nodes meet the conditions, all nodes have the right to put forward the consensus results first, and then directly recognized by other nodes, and finally may become the final consensus results. Taking bitcoin as an example, the workload proof is adopted. Only when more than 51% of the accounting nodes in the whole network are controlled can a nonexistent record be forged. When there are enough nodes in the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
(4) smart contract, which is based on these trusted and tamperable data, can automatically execute some pre-defined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and reliable, it is easy to carry out automatic claim settlement in some standardized insurance procts
Blockchain concept stocks revealed: only 58 of 197 companies have real business landing, and 37 of them are just hot
since October 28, blockchain concept stocks have performed well, with daily trading limit. According to zinc link, these & quot; Blockchain & quot; The main business of listed companies is not blockchain, and only a few of them have real application, most of them are still in the exploration stage
according to Dongfang fortune choice, on October 28, there were 153 companies in the A-share blockchain concept sector, and as of November 20, the number had increased to 197
through sorting out the public data such as interactive trading platform, announcement and relevant news, zinc link found that only 58 of 197 A-share blockchain listed companies have real business landing, and 37 companies said that they are not involved in any blockchain business at present

internationally, Japan has unconditionally supported bitcoin, the European Central Bank has said that it will not regulate bitcoin, bitcoin continues to prevail in the United States, and South Korea has incorporated bitcoin into its bulk commodities. Bitcoin is everywhere, and its popularity is so high that how can the price not rise
of course, bitcoin has not been smooth sailing this year, and it can even be said that it is "ill fated". What's wrong? Let's look below:
on January 5, 2017, bitcoin broke through the historical high of three years ago, broke through the 8000 yuan mark, and once soared to 8873 yuan
then, on January 6, the people's Bank of China and its Shanghai headquarters interviewed three bitcoin exchanges in Beijing and Shanghai, namely, fire coin.com, bitcoin.com and bitcoin China. They were asked to carry out self-examination on recent anomalies and carry out corresponding rectification
as a result, bitcoin prices plummeted to 4944 yuan a few days later
on April 1, 2017, Japan recognized the legitimacy of bitcoin and other virtual currency payment means, and the "Payment Service Amendment Act" officially signed by the Japanese cabinet came into effect. In addition, e to the uncertainty of trump policy, the US Securities and asset markets are volatile, and demand for risky assets is increasing.
from May 22 to May 24, 2017, the third consensus conference was held in New York. Miners and investors were full of expectations to reach a consensus on bitcoin expansion, and bitcoin prices ushered in a big explosion. The price of bitcoin broke through 20000 yuan on June 10, and reached a new high of 21388 yuan on June 11
at this time, the news about China's regulatory policy on bitcoin came out in June and intensified. The bearish sentiment of the market rose and the price of bitcoin kept falling. As of July 16, the price of bitcoin had dropped to about 13000 yuan
later, influenced by the good news of bitcoin bifurcation on August 1, 2017, bitcoin price rebounded again in late July and reached new highs repeatedly. On August 17, bitcoin price broke through the 30000 yuan mark, and then remained stable at a high level
on September 4, seven ministries and commissions jointly issued the announcement on preventing the financing risk of token issuance, and bitcoin prices plummeted to 21000 yuan, a daily drop of 27%
with the closure of China's virtual currency platform, the price of bitcoin continued to bottom out. On September 16, the price of bitcoin fell below 20000 yuan, with the lowest price of 16250 yuan
at this time, everyone thinks that bitcoin is over. But just two weeks later, on September 30, the FSA issued operating licenses to 11 bitcoin exchanges. This event triggered the upsurge of investment enthusiasm around the world, and the market was full of emotion, which promoted the continuous rise of currency price
facts have proved once again that bitcoin is like an invincible Xiaoqiang, facing heavy pressure, and its price rises instead of falling.
