R9270 mining test
The Internet "compares" the two symbols of human civilization - words and money, but the right is still unclear and vulnerable. Information exchange and wealth circulation still rely heavily on centralized organizations, such as credit extension and credit reference services
the underlying logic of blockchain is to store information in a common competitive accounting mode. Each page of encrypted account book is equivalent to a "block", and the transaction audit results are covered with tamperable time stamps and stored throughout the network. This "distributed general ledger technology" brings the ownership of rights and interests and the mutual trust of strangers, and brings the dawn for the free transaction of assets
as the underlying technology of bitcoin, why can blockchain become the most popular financial technology? As of June 18, a bitcoin is about 18750 yuan, and the total market value of global digital assets has exceeded 110 billion US dollars. There are 4321 kinds of digital assets, and there are more than 40 kinds of digital currencies with a market value of 100 million US dollars; Then, the free circulation between currencies, between chains, between digital currencies and legal currencies, and between physical assets and bit assets has become a huge pain point. How can we build a bridge from the atomic world to the bit world? What kind of sparks will the combination of artificial intelligence (AI), which is as hot as blockchain, proce? This paper tries to make a solution
first, the blockchain instry is in full swing, and the "comparative advantage" of domestic entrepreneurs is highlighted
blockchain was proposed by the foundational paper bitcoin: a peer-to-peer e-cash system published by zhongbencong in 2008, and bitcoin is the reward that zhongbencong created to reward participants for competitive bookkeeping, Mainly through the proof of work (POW) to "mine" and get the bonus. The "mining" is a process of competing the ability of consensus algorithm, which requires huge energy consumption. It is worth mentioning that at present, the four big bitcoin "mines" in the world are mainly concentrated in Southwest China and Inner Mongolia
in the public chain, any node is open, everyone can participate in the calculation of the blockchain, and can download and obtain the complete blockchain data (all accounts). With the improvement of the security level of the blockchain itself, many nodes in the private chain have access rights, and only specific licensed nodes can be publicly accessed
the emergence of "smart contract" is to solve the problem of converting the legal currency protocol into the protocol in the bit world. Smart contract can accelerate the real currency to become "programmable currency" in the blockchain. How to connect the legal currency and digital currency, and then connect the atomic world and the bit world, and promote the interaction and application of assets between the two worlds? It needs to be solved by "Bi Yuan chain"
"Bi Yuan chain" is built by Babbitt, the largest developer community in the domestic blockchain instry. Compared with other single asset blockchains, the "better than the original" blockchain interaction protocol is more suitable for complex interaction and interoperability of multiple bit assets, such as digital currency, usufruct, unlisted equity, creditor's rights, etc., based on smart contracts
China has the largest amount of investment in financial technology in the world, and blockchain is a parallel track with mobile payment, insurance, etc. bat has laid out blockchain in recent two years, network has reached strategic cooperation with circle (cross border payment), Alibaba and Ethereum have cooperated to develop financial cloud, Tencent's Micro bank has done alliance chain cloud service based on Tencent cloud, etc. By the end of April 2017, there were 455 blockchain companies in the world with a total financing amount of US $1.947 billion, and 61 domestic blockchain entrepreneurs financing companies
the mainstream workload proof mechanism (POW) in the blockchain is criticized for its narrow application range of "hash" calculation, resulting in a great waste of mining machinery and energy; Compared with the original chain, matrix operation and convolution operation are introced in the hashing process of mining, which makes the mining machine more friendly to artificial intelligence ASIC. The prosperity of mining machinery market in the blockchain has stimulated the supply chain of AI companies to ASIC chips, and the eliminated or idle "mining machinery" can also be applied to AI acceleration
conclusion:
although blockchain "burns brain", it does not affect the exploration passion of developers. This is not only the interest demand of bitcoin, but also the desire to truly return to the "value Internet" of freedom, openness and cooperation. Just as don Tapscott, the father of digital economy, compares blockchain technology to "Aladdin's magic lamp" that opens up a well-off society for human beings, with the birth of the public chain platform that opens up all kinds of currencies, chain areas and traditional financial asset transactions, multi asset biting is graally becoming a reality, and can provide artificial intelligence with open big data, controllable intelligent contracts and mining machinery acceleration, The era of currency and free assets predicted by Hayek, as well as the future convenience for people to invest and trade assets, must be based on the win-win and mutual promotion of artificial intelligence and blockchain technology

to identify mineral cards, first of all, check whether there is a large yellow area on the circuit boards on the back of the graphics card, and some of them must be. The reason is the aging of working for a long time
next, we look at the running points. Generally, the running points of mine cards are lower than those of ordinary cards, such as 3dmark software testing
if the price of the graphics card is several hundred lower than the normal price, it is likely that the card will be used
in fact, you can't tell whether your graphics card is a mine card just by looking at these photos. You can play some games that eat graphics cards very much, adjust the image quality to the limit that the graphics card can bear, and play more for a period of time. If the temperature is not too high (for example, close to 100 degrees), the screen won't go black and the screen won't crash, it's OK
otherwise, search for some software of ing machine on the Internet and the machine for a period of time. It's ok if the voltage is stable.
your graphics card is very good, and its performance is similar to that of gtx750ti, but Jianling's game does not support a card well, so it is not recommended to use a card, but recommend n card gtx750ti, which runs at the highest level of Jianling
hope it can help you, hope to adopt

there are few fake a cards.
all a cards are displayed in this way.
R9 270 270x 280 280x will be displayed in R9 200 series.
if you're still worried, don't use Master Lu, it's not reliable.
use gpu-z to detect and send a screenshot for you
No way, R9 270 detected R9 200 serials, you didn't buy 270
