一、Blockchain is not a magical technology!
Blockchain technology consists of applied cryptography, chained data structures, P2P networks and consensus algorithms. The application cryptography technology used is mature and applied for more than ten years, which you will use every day to brush your bank card and use your cell phone; the chain data structure is just an innovative data structure; the principle of P2P network may be used every day when you download; the consensus algorithm is various, which is really an innovative point, among which the most criticized “mining “mining” is the most famous. So blockchain technology is just a stack of some mature technologies! Some colleagues call it a “fidelity data paradigm”, and I think this definition is very accurate.
Two, blockchain technology is not the same as digital currency!
Blockchain (Blockchain) first appeared in Satoshi Nakamoto’s Bitcoin white paper, and digital currency (cryptocurrencry) is the name given to it by later generations. Blockchain technology is only a technology invented by Bitcoin in order to achieve decentralization and non-tampering. The so-called blockchain concept and digital currencies currently listed in A-share companies do not have any relationship! In October 2016, I started to look for manufacturers to carry out POC when I was looking for listed companies in the blockchain sector, and I found that they were playing with concepts without actual products and inputs in the exchange with several companies. The following blockchain is not special. The blockchain mentioned below is only the blockchain technology itself, not the digital currency, without special explanation.
Three, the current blockchain technology is very immature!
There is no doubt that blockchain technology has been developing well in these two years, and more technical and business people have invested in the blockchain business, bringing great vitality to it, but we should also see that blockchain technology is still very immature. How immature to give you an example, the current largest and most widely used fabric framework will cause the entire blockchain network unavailable because of network jitter; decentralized exchange bitshares this year, there was an event that could not be blocked out (can not be booked), the whole community can not handle until the founder BM to save the day; Ethernet in this year, there are many times the network blockage, I once I once spent 24 hours to transfer ETH from bitfinex ……, similar examples can be cited a lot, in the end, please evaluate for yourself whether it is mature.
Fourth, blockchain technology needs at least 3-5 years from large-scale application!
The blockchain world has and has only one mature application – digital currency. Whether the hype is very hot supply chain finance, trade finance, cross-border settlement, or a variety of gambling, distributed storage, prophecy machine, the actual is still very immature, many projects in some are still under development, some on line after few people are using is slowly dying. In general, there are two reasons to restrict the large-scale application of blockchain technology:
1. immaturity of technology: performance, privacy, operation and maintenance, operation and other aspects have not yet reached the level of enterprise-level applications;
2. business scenarios are not ready: for polycentric / decentralized application scenarios, it is extremely difficult for all parties involved to reach a business sense of “consensus”.
For performance litecoin was invented first, for privacy Zcash appeared, bitcoin upgrade is difficult to reach consensus, V God in the ethereum community stood out to centralized means to achieve business consensus, you can see the calculation is in the field of digital currency, these problems have not been completely solved, the current prosperity of the cryptocurrency circle is only due to the digital currency The current boom in the cryptocurrency world is only caused by the premium price of
V. Blockchain technology cannot solve the human problem!
In sociology, trust is considered a relationship of dependency, where a trustworthy individual or group means they pursue time policies, codes of ethics, laws and prior commitments. The trust claimed by blockchain is not this dependency relationship, but the ability of a person to trust the blockchain algorithm to protect their information or assets. Trust in people or groups is a sociological problem, and it’s safe to say here that blockchain won’t solve it.
Six, over 90% of digital currencies are Ponzi schemes!
I personally think Bitcoin is valuable, but over 90% of the rest of digital currencies are Ponzi schemes. Because they may not be blockchain at the bottom, or even just a token ready to be attached to ethereum for a long time. I don’t understand why they need to issue token if they are going to be attached to ethereum for a long time, wouldn’t it be better to use ETH directly (by vitalik)? I think there is only one reason for these ICOs, and that is they want to make double profits from the ETH they raise and the premium on the token they hold! I once saw a team of more than 20 people spend up to 11 million RMB in a quarter, and this is still a public financial, do you think this is normal?
A project I personally experienced, ownership
I think it’s time to throw a pot of cold water on the blockchain, individuals have been involved in the buying and selling of digital currencies and are equally optimistic that this market will still fly for a while, but I also believe there will definitely be a day of ebb, when the ebb is only those Only those businesses and communities that really have something to offer will survive. If you don’t even have a wallet by now and don’t even understand the basic principles of blockchain, it is still not recommended to participate in this market, because it may bring you huge losses.Lost.
In September 2017, in the People’s Bank of China and other seven ministries jointly issued the “Notice on Preventing the Risk of Token Issuance and Financing”, it is clearly pointed out that the act of token issuance and financing (ICO) is suspected of illegal fund raising, illegal issuance of securities and illegal sale of tokens and vouchers, and other illegal criminal activities. As ICO projects around the world are gradually being retired, the issuance of Xunlei’s “Chainke” (formerly known as “PlayCoin”), represented by a type of coin called “The model of “issuing virtual digital assets with a mining machine as the core” (IMO) is worthy of caution, and there are risks and hidden dangers.
Since October, the IMO model of issuing “virtual digital assets”, including chain grams, flow coins, BFC points, etc.. The company’s “chain grams”, for example, are actually used to replace the fiat currency payment obligation for the services contributed by participants, which is essentially a financing act and a disguised ICO. The company’s main goal is to attract a large number of people who do not have the ability to identify them.
The China Internet Finance Association calls on consumers and investors to recognize the nature of the relevant models, enhance awareness of risk prevention, rational investment, and not blindly follow the hype. The IMO model and all kinds of ICO and “virtual currency” trading venue services continue to be opened for domestic residents through the deployment of offshore servers, found to be involved in illegal financial activities, can be reported to the relevant regulatory authorities or the China Internet Finance Association, which is suspected of illegal crimes, can be reported to the public security authorities. Members of the Internet Finance Association of China should strengthen self-discipline, resist illegal financial activities, and do not participate in any acts involving ICO or speculation “virtual currency”.
