ASIC blockchain computing terminal
1. The distribution method of bitcoin is pow (proof of work), which means that if you want to get bitcoin, you have to calculate a mathematical problem with a large amount of calculation. Whoever calculates it first will be allocated the new bitcoin. POW mechanism has great advantages: good security, but there are also a variety of problems: huge energy consumption, low efficiency, the most important thing is that there is a monopoly of mining rights, without joining the mine pool, indivial miners can not dig bitcoin
2. This year's hottest EOS project adopts the dpos mode (entrusted POS), while EOS only allocates 5% of its share! The vast majority of EOS are distributed in the form of ICO (private placement), and the ETH obtained is used to support the development and maintenance of developers. In other projects, most tokens are distributed in the form of ICO, usually 20% of the shares are left to developers, and more than 50% of the shares are used for ICO, and the remaining share users can participate in the allocation
3. The POS mode adopted by quark blockchain is to freeze QKI (quark integral) to obtain computing power, and allocate the output by computing power, with 7200 points per day, 10% of them are allocated to the developer account, and the remaining 6480 points are distributed to each user according to the average computing power. The advantage of POS is that there is no threshold for mining, and everyone's output rate is the same. Take today's (June 19) data as an example: today's total computing power is 854447.792, and the output of each unit's frozen computing power is 0.007583845. For each user, the output is extremely fair
4. Our quark blockchain allocates 90% of its output to users
5. OTC transactions are free of handling charges, and quark blockchain is open, transparent and traceable.
1. POW workload proof, which is familiar with mining, calculates a random number that meets the rules through and or operation, that is, obtains the bookkeeping right, sends out the data that needs to be recorded in this round, and stores it together with other nodes in the whole network after verification
advantages: complete decentralization, free access of nodes
disadvantages: bitcoin has attracted most of the computing power in the world, and other blockchain applications using POW consensus mechanism are difficult to obtain the same computing power to ensure their own security; Mining causes a lot of waste of resources; The period of reaching consensus is long, which is not suitable for commercial application.
2. Proof of rights and interests of POS, a mechanism of upgrading consensus of pow; According to the token proportion and time of each node; It can rece the difficulty of mining in equal proportion, so as to speed up the speed of finding random numbers< Advantages: to a certain extent, it shortens the time to reach a consensus
disadvantages: mining is still needed, which does not solve the pain point of commercial application in essence
3. Dpos share authorization certification mechanism is similar to the voting of the board of directors, in which the coin holders cast a certain number of nodes to verify and account on their behalf
advantages: greatly rece the number of participating verification and accounting nodes, which can achieve second level consensus verification
disadvantages: the whole consensus mechanism still depends on token, and many commercial applications do not need token to exist
4. Pool verification pool, which is based on traditional distributed consistency technology and data verification mechanism; It is a consensus mechanism widely used in the instry chain at present.
advantages: it can work without token, and realizes second level consensus verification on the basis of mature distributed consistency algorithms (pasox and raft)
disadvantages: the degree of decentralization is not as good as that of bictin; The multi center business model is more suitable for multi-party participation
it has great advantages in using consensus mechanism to ensure data consistency (the consensus mechanism is first proposed by ripple, and the network transaction synchronization mechanism with data correctness priority. In the consensus network, no matter how the software code changes, if you can't reach a consensus, you can't enter the network, let alone fork)

PS: a little black, although the consensus mechanism can absolutely ensure that there will be no hard bifurcation at any time. However, the disadvantage of this mechanism is obvious, that is, it is much longer than the current bitcoin network to reach a consensus with other nodes. In extreme cases, the consequences of disconnection in ripple consensus mechanism network are also very terrible
it is possible that one day after the power failure in your home, the whole system will no longer be able to reach a consensus with other rippled nodes (in fact, the consensus mechanism requires more than 80% of the nodes to acknowledge your data before your submission will be accepted by other nodes, otherwise it will be rejected by exclusive nodes), Even you can only empty all your 500 GB data and resynchronize to connect to other ripple nodes
so at present, the existing rippled end is not suitable for civil use (if it is commercial, the impact is relatively small. For example, RL's own rippled node is hosted in Amazon cloud data center. If it has no response for a long time, it can make high claims, and there is almost no break in that place except for large disasters). This is one of the aspects RL has always wanted to improve.
Blockchain is a new application mode of distributed data storage, which is an important concept of bitcoin. At present, there are 35 stocks associated with the blockchain concept in the A-share market, of which 6 blockchain concept listed companies are traded on the Shanghai Stock Exchange, and 29 blockchain concept listed companies are traded on the Shenzhen Stock Exchange
according to the correlation of blockchain, the leading stocks of blockchain concept stocks are most likely to be born from Xinchen technology, luyitong and Sifang Jingchuang
Xinchen Technology: on September 29, 2016, the company said in the interaction that the company is now doing research and development of blockchain technology
Lu Yitong: the company plans to raise 67.9691 million shares of additional shares of RMB 24.57 per share, and the total amount of supporting funds will not exceed RMB 1.670 billion, which will be used to pay the cash consideration of this transaction, construct the block chain ASIC chip instrialization project, artificial intelligence ASIC chip R & D center, chip proct marketing and service network, etc
Sifang Jingchuang: on May 31, 2016, the inaugural meeting and the first general meeting of the financial blockchain cooperation alliance (Shenzhen) was officially held in Shenzhen Wuzhou Hotel, and the company was one of the members of the meeting
at present, China's blockchain instry mainly focuses on computing infrastructure, radiates digital currency, and derives to the penetration process of blockchain application. Infrastructure includes chip miner, mine pool and cloud computing power. Digital currency, wallet and exchange constitute the monetary system. Asset authentication, financial services and charity form a rich application ecology. From the development trend, the mining machine has experienced CPU, GPU, FPGA, until now through ASIC chips to customize mining, we can see from the mining machine calculation force curve that the mining machine calculation force has been in a soaring trend.
Today, geometric car released the rendering of its new car geometric C, and put forward a new concept -- the new favorite of pure electric
Therefore, the new geometric platform means that geometric C may have a new electronic and electrical architecture, which means a lower level architecture with higher integration, higher computing power and higher openness, providing a lower level guarantee for subsequent OTA, joint development and "feeding"■ driverless and 5g
according to the official news, geometric C will apply Geely's latest technological achievements in the field of driverless and carry Geely's self-developed "intelligent tracking driverless system". The system is the first domestic automatic driving technology that combines the car end, cloud end and field end, and will be equipped with 5g in the future to realize full road condition, full scene and seamless high-speed connection. It can turn on 100% independent parking function in outdoor and indoor multi scene. In the future, driverless scenes such as unmanned parking, unattended, and unattended express delivery will be constructed in stages to continuously evolve
well... It looks very powerful. If it can be realized, it can be called the comprehensive commercial use of 5g + Internet of things
based on my current knowledge and practical experience, I really can't imagine what "all road conditions, all scenes, seamless high-speed connection of automatic driving" and "100% autonomous parking" would look like. Because even Tesla, which is currently the leading company, can only drive automatically under specific road conditions (sometimes not very smart); The success rate of automatic parking is worrying. Every time I test this function, I'm more nervous than my subject 2
therefore, for geometry C's unmanned driving, I really hope it can make a big splash and hit Tesla in the face
Of course, it's meaningless to talk on paper. It's mules or horses. Let's take a walk! When we get the test drive, we will bring you detailed experience and evaluation in time. Please look forward to it To sum up, geometric C is an electric vehicle with good appearance, smart mind and enough enrance; In addition, in terms of driverless and intelligent Internet, it seems to want to bring us unprecedented experience. I very much hope that it can become a pioneer or leader and a Chinese brand leading the world trendthis article comes from the author of car home, which does not represent the standpoint of car home
