Telegraph blockchain
blockchain refers to the technical solution of collective maintenance of a reliable database through centralization and distrust in the past, and it is a technical way for the whole people to participate in bookkeeping. Previous bookkeeping methods were all centralized and needed centralized intermediary, whether it was traditional government, financial institutions, notarization institutions or emerging e-commerce platform and online payment platform
in economic hypothesis, information is sufficient. In fact, it is precisely because of insufficient information that there are very large intermediaries. The existence of intermediaries increases the transaction cost and raises the transaction threshold. In essence, blockchain technology is a large-scale collaboration tool. It makes direct value transfer possible by using pure technology for the first time, and continues the trend of Internet decentralization and disintermediation. Disintermediated blockchain technology will greatly subvert the information intermediary instry
blockchain technology is the basic technology for building bitcoin data structure and encrypted transmission of transaction information, which realizes the issue and transaction of bitcoin. The core of blockchain technology is that all the current participating nodes jointly maintain the transaction and database, so that the transaction is based on the principle of cryptography rather than trust, so that any agreed parties can directly carry out payment transactions without the participation of a third party
technically, a block is a data structure for recording transactions, reflecting the capital flow of a transaction. In the system, the transaction blocks are connected to form a main chain, and all the nodes participating in the calculation record the main chain or part of the main chain
a block contains the following three parts: transaction information, hash formed by the previous block and random number. Transaction information is the task data carried by the block, including the private keys of both parties, the number of transactions, the digital signature of electronic currency, etc; The hash hash formed by the previous block is used to connect the blocks and realize the sequence of past transactions; Random number is the core of the transaction. All nodes compete to calculate the answer of the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for updating, so as to complete a transaction.
A vigorous "blockchain movement" is sweeping like a wave, threatening everyone around. From last year to this year, the debate over blockchain has never stopped. Is blockchain, as its advocate Chen Weixing said, the "spring of mankind", the "antidote to the global economic collapse", or as his doubter Zhu Xiaohu said, "blockchain is a fake outlet, and there is nothing left except currency speculation"
we think that this instry needs standards, otherwise we will talk about blockchain for a long time, and the concept of talking is not the same, and even some enterprises claim to make their own blockchain, and they just change the database. With the authoritative standard of trusted blockchain, we can screen out the enterprises that obviously sell dog meat, and let the enterprises that really do blockchain technology get endorsement
Ce: how does Tencent solve the problem of talent scarcity in the blockchain field
CAI Yige: our technical talents are basically transformed from Tencent. The blockchain instry is very new, and few people have done blockchain. Just like the arrival of mobile network in those years, it's very difficult for you to recruit Android and IOS developers. We all cultivate ourselves
5. There is no project white paper, or the quality of the white paper is poor, all of them are "fake" blockchain projects
6. There is no open source, all of them are "fake" blockchain projects
7. All of them are "fake" blockchain projects that claim to be the general points of XX enterprises
8, The above nine points are applicable to more than 99% of the current blockchain projects. The following are some auxiliary knowledge points for strengthening judgment
first, if there is no venture capital investment, it is likely to be a "fake" blockchain project
Second, if there is no enterprise mailbox, it is likely to be a "fake" blockchain project
Third, if there is no Facebook, Twitter or telegraph group, it is likely to be a "fake" blockchain project
Fourth, if it is stated in the white paper or official website, it can be traded on XX trading platform in the future, Most likely, it's the "fake" blockchain project
v. the team members of the project side have low exposure, most likely it's the "fake" blockchain project
VI. there is no detailed project progress planning schele in the white paper, and most likely it's the "fake" blockchain project
the above 15 knowledge points are summarized by my own personal experience from 14 years to now. Now the blockchain investment instry is a mixture of good and bad. For the investment of a project, we need to be cautious. Any investment behavior is risky. How to control the risk, rece the risk in the minimum range, is the current investors should understand. We must make rational investment, not blindly follow the trend, and make investment judgment after a detailed understanding of the project
