Proof-of-stake (POS) models are becoming highly desirable in blockchain consensus designs, especially with the "Casper" Upgrade underway for Ethereum, the second largest cryptocurrency by market cap. Yes, the immediate reason is that it's more energy efficient (reduces computational costs) as opposed to Proof-of-work (P OW) which is highly resource intensive, but there ' s more. POS, in general, takes individual Digital Signature to prove ownership

Ethminer doing some mining Again, you'll have a wall of stuff stream Past-this is Ethminer starting to does its business. I left it for a few hours and came back to some ether. writing a contract Once you have some ether, can stop mining and start writing! Parity has a built in contract development tool, which are pretty nice. Make sure you can-it by going the the Parity Web interface and ensuring

cryptocurrency, such as bitcoin and how it works, we recommend that you take a look at the first few chapters of Bitcoin book by Andreas Antonopoulos and then read the Ethereum white paper. (see Http://ethfans.org/posts/ethereum-whitepaper for the Chinese version of Ethereum white paper) If you think the chapters in the White paper are too obscure, you can also get to know Ethereum directly. Doing development on Ethereum does not require you to under

. and blockchain technology in addition to the emphasis on trust transmission, but also the consensus mechanism, that is, the more groups to achieve consensus, the greater the value of the network. At the same time, Wang Dong also believes that ordinary consumers need to pay attention to the blockchain landing matters. As large as securities trading, property rights and property transfer, small to commercial points, can be through the blockchain technology to make more open and transparent e

Today writes the shortest path The Floyd algorithm (has the translation is called Freud, but this wonderful translation is used to read the good ... ）。The essence of this algorithm, broadly speaking, is actually DP (Dynamic programming). In fact, supposedly, the algorithm should say what greedy, search, DP, two points of the basic algorithm, but I think too broad things for people who do not have the basis to speak up unclear, or write a comparison of some typical algorithm is better. And this s

tell the truth, because before the C language learning is not very good, I can learn Java without great confidence, but learn elder sister of this words, cannot but say is a kind of encouragement and spur to me. In the first few weeks of study, the weekly blog I will be a serious summary, but with the subsequent course more and more tense, I sometimes a little slack, but, almost every time the blog summed up, learning elder sister will be serious eva

The topic is a bit big, but there are some anger!Our gateway products are currently in the system testing phase, not too smooth, is too bad! All the slack, including me! I'm still looking for a chance to hit the counter, except slack! By the way, scorn the tester, hoping to produce an imagination that the problem he found is not a problem, but because of his ignorance caused! Just yesterday, when the opport

If the design trend stays in the discussion of color, interactive effect and card-interface, we may be left behind in two years. Today, foreign Chinese design director spell and his classmates talk about 5 UX trends that will affect the way people live (the rise of vr/ar, screen-independent interaction, time as the core measure of design, large data design, etc.). 　　The rise of 1,VR and AR Fastcodesign at the beginning of this year's article The Most Important design jobs of the Future predict

About the study material, the nest to see is this articleIts definition of the data structure has been more clearly described, I am here to explain only a few small places and give their own implementation codeFirst of all, we all know Dijkstra, an algorithm used to solve the single source shortest path.Time complexity O (v^2)Then its optimization:Heap +dijTime complexity O (vlgv+e)Here are the highlights:We all thought that the dij+ heap, which was written by two forks, was vlgv+e, but what was

In fact, we have a long tail keyword optimization is a kind of wisdom, that is to circumvent the enemy's sharpness, in the local scope, the formation of the enemy's advantages, so that can be broken, successfully defeated the enemy!

Reinstalling the system is not difficult, but after installing the system do you know how many things we have to do? This can not tolerate the slightest slack, once sloppy, will likely lead to naught, even may cause data loss, information leaks! It is an indisputable fact that Windows systems are used more slowly. Therefore, it is unavoidable to reinstall the system using Windows. Of course, reinstalling the system is not difficult, but after install

here about the standard type are not mentioned. Take a look at the relaxed type: The relaxation type is the equality of the other conditions except the non-negative constraints. Sigma (J=1...N) AIJ *XJ Can be turned into S=bj-sigma (J=1...N) AIJ *xj s>=0 form where S is a relaxation variable. The basic form of relaxation type: Z=v+sigma (J=1...N) CJ*XJ for (i=1;i Right here insert some definitions to help understand With these bedding, we can formally introduce the simplex algorithm. The simpl

After the rapid surge and bursting of the ICO bubble, Bitcoin still sings, breaking the $9600 mark recently. As a digital cryptocurrency independent of the monetary system, the essence of Bitcoin's success is due to technology-blockchain security and privacy that underpin Bitcoin's core value.Referring to blockchain, asymmetric cryptographic algorithms and hashing algorithms are two technical terms that cannot be avoided. In particular, hashing algori
