quantum chain
zilliqa project's token name is ZIL, which has been circulated and traded on 23 exchanges. Mainstream exchanges such as fire coin and coin an support it, so it is very convenient to participate. ZIL's maximum supply is 21 billion, of which 12.6 billion will be released directly through contracts, and the other 8.4 billion will be released in the form of mining awards within 10 years
the main network of zilliqa will be launched at the end of 2018 or the beginning of 2019, and the mining reward is rich, especially in the early stage. The electric power cost of zilliqa mining is only 1 / 9 of that of Ethereum, so it is more feasible with less energy consumption. In addition, mining can be carried out through GPU graphics card miner, and can simultaneously double dig ZIL and eth, bringing higher benefits for miners
pay attention to "zilliqacn" to learn more about the progress of the project.
in China, there are blockchain alliance organizations like R3, Ethereum, decent and other blockchain projects.
(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
Shenzhen's IT leaders summit has come to its 10th year. As the annual program of China's Internet giants gathering in Shenzhen, Shenzhen and its star enterprise Tencent are trying their best to entertain those bigwigs who come from afar
Zhang Shousheng, Professor of Stanford University, USA:
the generation of blockchain can create a data market. In my mind, the ideal future world is that everyone has their own data, which is a completely decentralized storage. In this way, it is impossible for hackers to hack everyone's personal data and then use some encryption algorithms, In the blockchain, it can really protect personal privacy and make very good calculation
artificial intelligence needs data, but data is often monopolized by centralized platforms, which hinders innovation. Encryption economics creates a data market with correct incentive mechanism for data providers, and artificial intelligence can take off on this data market. In a fair data market, the value of data is measured by cross entropy. In our society, some minorities will be discriminated against. However, in the encrypted data market, the data they provide will receive the most attention. Encryption economics can offset all kinds of prejudices in current social economics
Ni Zhengdong, founder and chairman of Qingke group:blockchain is a direction of technology. Technically speaking, how much value blockchain can have is still a question mark, which may have great value, but today, the application has not been implemented. We don't deny the value brought by blockchain. In terms of technology, I think it is very valuable and promising, but no one can know how big the prospect is
in the financial field, blockchain is absolutely subject to supervision and is not a free world. Political orientation should be correct. In the field of blockchain, we should adhere to the leadership of the party and accept supervision. digital currency can not be anarchism, it needs the correct guidance and supervision of the government
now we all focus on the real economy, whether it's entrepreneurship or investment. I think the blockchain itself should create value. If a company issues a coin and doesn't know what to do, it will suddenly be worth tens of billions of dollars, which is completely divorced from value creation
as for the title of classical investors, it's just a joke, or to grab an eye and create some concepts. I believe that 99% of the projects or 95% of the projects will be done by classical VC in 2018
Yan Yan, founding partner of Saifu Asia Investment Fund:blockchain is very popular, but in fact, institutional investors participate very little. At present, many of them are indivial behaviors. More than 95% of ICO in China is money making, and the really large first-line institutional investors actually participate very little. To be honest, these people can become first-line institutional investors. They are not fooled. They know more than you, see more than you, and read more books than you. How can they be so stupid? They make money from people with lower IQ than you
Wu Ying, chairman of the digital China Federation:
pays close attention to the blockchain and has made a certain investment layout here. Among the three or four companies invested, there are 13 patents. Among the listed companies previously invested, 2 are doing blockchain business. However, it will take some time for blockchain to break out. On the whole, it will take about three years for blockchain to have a direct impact on the economy, but it may be faster than the United States in some aspects. Focus on the application of right protection of works of art, and set up an angel fund to invest in blockchain in the future
talk about big data: the obstacle of data exchange lies in the system rather than technology
Wang Jian, chairman of Technical Committee of Alibaba Group:
data is the material basis of digital economy. Data can neither be shared nor opened, but the value of data can be shared. Uber and didi are great changes in human behavior. What have they changed? In fact, Uber and didi are not sharing cars. In the past, they came out from home in the morning to tell their parents where to go. But with Uber and Didi, you can actually share with a company about where to go today. This is the real change
Guo Wei, chairman of the board of directors and chairman of Digital China Holdings Co., Ltd.
from the perspective of the government, he highly recognizes the value of data, but it is very difficult to implement it. Data itself has a natural segmentation, different people have different cognition of data. Another very important point is the division of interests. Due to the huge benefits brought by mastering the data, some people are not willing to release them. If released, it means the loss of privileges, which is the most difficult part in the process of data access today
from the perspective of today's technology, there is no problem to achieve data access with our technical ability, whether it is traditional technology or the latest developed technology. But the most important obstacle is the system
Yan Yan, founding managing partner of Saifu Asia Investment Fund:
the opening of data is a double-edged sword, and social data should not be open to everyone, because data is useless to more than 95% of people, and there are less than 1% of people, so it is harmful to the society to give them data
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.
bitcoin cash BBC can be said to be a variant of bitcoin. Bitcoin is said to have a limited number, only 21 million, but the real number can not be verified. At present, the fission of the cash BBC makes people believe that bitcoin can be infinitely fission
the essence of currency is a combination of national strength and credit. Bitcoin, as a virtual currency, has no guarantee or endorsement from any country and no legal protection
If a country's currency does not have enough national strength to guarantee its credit, it can only rely on the old hard currency: gold
gold is credit
at that time, with the emergence of bitcoin, some people thought that the golden age had passed, so they compared the emergence of bitcoin to mining. However, there was only one thing in the world called gold, and more than n Ethernet coins, Wright coins and so on appeared around bitcoin. Such virtual currencies can invent countless varieties
it can be imagined that once the virtual currency is destroyed, the real currency gold will lead to long-term good
1. At present, the biggest positive factor for gold is the US dollar. Recently, the continuous decline of the US dollar has made gold form a w double bottom
2. The second relationship of gold is international geopolitics. Any disturbance can make gold as a hedge fund soar
The third related account of gold is the world's hard currency. When a country's currency collapses, unless you have the world's hegemonic currency such as the US dollar, only gold can let you avoid this super risk At present, China's gold reserves have quietly ranked second in the world, from 1000 tons in 2009 to more than 4000 tons at present. Some people expect that in three years, China's gold reserves will surpass the United States and jump to the first place in the world According to the data recently released by the China Gold Association, China's gold bar consumption in the first half of 2017 rose by 51.09% to 158.40 tons year on year, and the national gold consumption rose by 9.89% to 545.23 tons year on year! Because the private sector has more than 1600 tons of gold reserves In 2013, some experts pointed out that China's national gold reserve should be more than 5000 tons, and once a currency war broke out, it could occupy a favorable position On the one hand, the internationalization of RMB is guaranteed by the comprehensive strength of the country; on the other hand, it has a lot of gold reserves
gold is a combination of money, finance and commodity. It has become a belief of natural currency for thousands of years, and the future of gold is worth looking forward to
