Is blockchain a real fire or a virtual fire
blockchain is not deceiving, but deceiving people under the guise of blockchain. In fact, blockchain scam is to make use of people's ignorance of the technology, and then fraudsters rely on various and fancy means to set up scams. Many people only look at the surface when making investments, and finally fall into the trap of high profits
in the current society, more and more people are willing to take this risk to make investment in order to get rich returns, but not all of them can make profits. After all, where there are interests, there are many people waiting, and they will set traps for people to take the t

precautions
blockchain is a technology. In short, this technology is a new way of data management based on cryptography. Blockchain technology has broad application prospects because it has the advantages of decentralization, non tampering, tracing and so on. And issuing currency is a kind of behavior derived from blockchain technology. At present, the vast majority of blockchain applications which mainly focus on currency issuance and speculation are suspected of illegal fund-raising
blockchain technology is still in early development, and it is difficult to apply it. If you only rely on a white paper to claim that there is an application, it is a deception in itself
Almost everyone, even those who don't believe in universal certification, has a positive view on blockchain technology, because it may change the whole world. However, it has been ten years since the invention of blockchain technology, and we still do not really use blockchain technology. Some people say that bitcoin is based on blockchain technology, so with its development, the main use of blockchain is as a payment system or value storage means
there are many examples
there is no doubt that blockchain technology can be integrated into almost all sectors of modern life (including the above sectors). However, it has been nearly 10 years since the birth of blockchain technology, and no field has replaced the original technology with blockchain technology. These ideas are good, but the technology is too slow to implement
for example, if you are a woman, every time your boyfriend says something disgusting to you or promises to buy something for you, you immediately record it and send it to you and all his friends, classmates, colleagues, as well as various groups and circles of friends, so that he can no longer resist. This is called blockchain
the core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the high cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.
in many cases, under the guise of charity and helping others, you are asked to deposit a sum of money first, with 1% interest every day, automatically withdraw one month, even with 30% windfall profits. Normal people know that this is not normal, because there is no instry that can make 30% profit every month. Where does the interest come from? The answer is that the new entrants will give you the money they have saved. Whether they can earn 30% in a month depends on whether there are new entrants to pick up their disks
under the stimulation of huge profits, all the people who join MMM are charging money like poisoning. At the same time, they try their best to persuade their relatives and friends to join in, because the recommender can get extra benefits by joining. This is also the common feature of all MLM organizations. They must have fresh blood to join, otherwise they can't play
since the monthly interest rate is 30%, we can accurately calculate the growth rate of this scam. After 12 months, the total scale will grow by 23 times, after 18 months, the scale will grow by 112 times, and after 2 years, the scale will grow by 542 times. Once the new capital can not meet 30% in any month, it will collapse< However, mavroji, the founder of MMM in Russia, is not a mathematician at all. He played this trick in Russia in 1990, and millions of people lost money when it collapsed. Therefore, he was arrested by the Russian government and sentenced to four and a half years' imprisonment
it can be simply compared to
water ghost mode
people who are ghosts have to find a ghost to replace them. So I will try my best to tell you that he is very moistening in the water, so I can pull a few people down to die and then I can leave.
I hope you can adopt my personal opinion

different investors have different views. No matter they think it's a bubble sworn faction, or they regard it as a good candidate for the draught, they do not deny that the block chain is a tool that people can not ignore to change the society. Therefore, it is an important choice to join the blockchain investment platform.

Blockchain is not just a fire. It's a fire in China, but we don't know much about it. But it caused a certain sensation in the world. The historical background is that in 2008, the creator of bitcoin, Tsung Nakamoto, proposed the concept of "blockchain" in the white paper on bitcoin, and founded the bitcoin social network in 2009
several main features:
-
blockchain is essentially a decentralized database. The information in our life is centralized. For example, if you transfer money to bank a, bank a will transfer it to bank B, or more intermediaries, so as to transfer it to foreign countries or other places. Any information is transferred to a central station and redistributed. In the blockchain, all data are scattered, and the data interaction is direct, from the starting point of data to the place where it needs to be received. So data transmission is faster, more direct, and will not be manipulated
-
why is it called blockchain? Take bitcoin blockchain as an example. Every 10 minutes of bitcoin transaction information in the world will be recorded in a block, and the 10 minutes of data storage is monitored by all users. The information is transparent and cannot be tampered with. After ten minutes, the next block is generated, and the new block is linked with the previous block. If someone wants to tamper with the information of a block, he must tamper with the information of all blocks before that, which is impossible with the current technology
What is the use of < / OL >
1. Think about using blockchain in enterprise applications to provide more flexible, secure and efficient business processes and distributed, independent markets. Blockchain allows asset owners to track and trade valuable things, such as outstanding invoices, on a transaction "chain" that is more secure, transparent, private and self-coordinating. This capability improves the speed and flexibility of cash and asset management. For example, you are afraid to buy fake things, because a manufacturer transfers proction to several middlemen, and then you buy through middlemen, not manufacturers. If all the data is distributed, point-to-point and transparent, you can buy and pay directly from the manufacturer
The automation market of other assets will be diversified. In essence, because the software itself is controlled and open architecture, and visible to all transaction participants, the transaction based on blockchain can rece the demand for third-party supervision. If the enterprise can publish the value information to multiple potential buyers, and for all buyers, the content can be trusted and visible, and the seller can't sell again, then an open and transparent competitive environment will be formed when purchasing, and the seller can get better prices3. Rece business transaction friction. Managing spending is a challenge for most organizations. However, blockchain enables enterprises to create self-management networks for suppliers and partners, realize contract automation, real-time payment, tracking of goods transportation, and visibility of the whole supply chain. For example, if a company uses refrigerated containers to transport perishable goods, when the container temperature exceeds a certain threshold, the IOT sensor on the truck may call the smart contract on the blockchain. This will cause the corresponding order to be cancelled, and it will also be able to automatically create a new order, so that a second batch of goods can be sent immediately. Trucks with faulty refrigeration equipment can also go to the repair Office for repair
This kind of network can rece transaction errors and information omission by recing or eliminating human-computer interaction. Moreover, by connecting buyers and sellers directly, transactions can become faster. Manage and secure decentralized private records. Its traditional instry practice is to rely on a third party, using firewalls and restricted access to protect their shared information database. And frequent data leakage events show that this approach is not very ideal. A fundamental advantage of blockchain is that each indivial data record or element is encrypted by the key of a blockchain member. Cybercrime may need to obtain each key of each member in order to access all the blockchain data. This is not to say that blockchain can guarantee 100% security of all data, which helps to rece the possibility of exposure of a large number of private records5. A reasonable application is the record of employees or students. Employers, ecational institutions and even instry certification bodies can add new qualifications, grades or work places when necessary. Imagine giving employees a key to access all their employee records as part of a secure blockchain containing human resources. Indivials can safely share their university transcripts or employment history with other companies or ecational institutions without relying on unreliable and easily falsified faxes. Trace the origin of procts and raw materials. Blockchain can help ensure proct quality and safety by simplifying the tracking and positioning of procts and raw materials in use. For example, if an automobile manufacturer forms a quality centered blockchain including parts suppliers, parts assemblers, quality control suppliers and public management organizations (such as the National Highway Traffic Safety Administration). Then the recall process of defective parts will be faster. It makes sense to think that thousands of people die every year because of defective car parts
to sum up, blockchain is a kind of chained data structure that combines data blocks in chronological order in a sequential way, and it can not be tampered with and forged by cryptography. In a broad sense, blockchain technology uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, and uses cryptography to ensure the security of data transmission and access A new distributed infrastructure and computing method (reference network) for programming and operating data by using intelligent contract composed of automated script code.
