the maximum value of the function. The results are shown in the following illustration:  As you can see, the most likely final price estimates are similar, all above $5,0000. It is noteworthy that this estimate is not necessarily the final result, but it can be better used to find the confidence intervals for future final prices. In this case, the bitcoin price 80% confidence interval will be between 13,200 and 271,277 dollars. Another way to

you that our ordinary computer, can solve the problem of the probability of competition, than the company 10 times the Big Lotto is still low. System can be based on the entire network of computer computing power, constantly changing the difficulty of the competition, so that the control in about every 10 minutes or so only one person can solve the problem. So at the very beginning, when the whole Bitcoin

This article explains the contents, purposes and results of Bitcoin transactions. The explanations below apply to novice and intermediate Bitcoin users.As an encrypted currency user, you need to be familiar with the rudiments of trading-for your confidence in this evolving innovation, and as a basis for understanding emerging multi-signature transactions and contracts, both of which will be explored later i

principle is that when you want to download the movie "Wolf 2", the system will extract the "Wolf 2" hash value, through the search for this hash, you can find all the users who have "Wolf 2", everyone together to carry out point-to-point data transmission, emule itself does not have to establish a database, only build platform on it. Because of the compression characteristics of the hashing algorithm, the "Global Search" event is low cost and feasib

this is a stable job? In fact, the PPS model of the mining pool in order to avoid the risk of loss, often will be charged 7%-8% high fees.Comparison. I personally suggest that beginners can try PPS, so that although the low income, but every day more stable, not easy to be frustrated, and pplns in the long run, although sometimes less, but due to lower fees, the overall benefits will be better.

In the Bitcoin blockchain, trading is the core of the content. Through the above, we know that bitcoin through the public private key system based on cryptography, the initiator of the transaction can use their private key to sign the transaction, others can use their public key to verify, which mathematically guarantees the security of the user funds. So how is the transaction structured? Simplified Model

(approximately 4 years). The network tries to create 6 chunks per hour. Every 2016 blocks (approximately two weeks), all Bitcoin clients compare this target to the number of blocks actually created, modifying the percentage of difficulty the chunk collects to maintain this goal. The client considers the "longest" blockchain to be valid. The "Length" of the entire blockchain refers to the chain with the most difficulty added, rather than the chain wit

If you are wondering why this are part 4.1 instead of Part 4, and why I ' m not talking about continuing to builds the local JB C, it's because explaining Bitcoin ' s Proof of Work difficulty at a somewhat level lower a takes of spaces. So unlike what this title says, this post in the Part 4 are not how to build a blockchain. It ' s about how a existing blockchain is built. My main goal of the "Part 4 post is to have one section on the

Google released 72-bit quantum computers. Will bitcoin be safe? At the annual meeting of the US physics conference held in Los Angeles this year, Google launched the world's first 72-bit quantum computer, Bristlecon, to achieve a low error rate of 1%, it is the same as Google's previous 9-bit quantum computers. This processor not only helps scientists explore quantum simulation, but also applies quantum opt

Exploring the technology of block chain (I.), constructing the Genesis block of the Bitcoin May one, 2017 0. Understanding block chain technology from a simpler perspective If we use search engine to search block chain, we see most is go to center, distribute, trust, can't change, can't forge, consensus, work proof, POW, equity proof, POS, public chain, private chain, Alliance chain, Intelligent contract, future, etc. a bunch of similar words. Now let

So what exactly is digging mine. How do miners get bitcoin by digging a mine? This requires the POW (work proof) consensus mechanism that is used in the Bitcoin block chain system. PoW (work proof) consensus mechanism Tell a story first: There is a village, and many things in this village need to be made together. For example, one day, the village chief needs all the villagers to make a decision. The villag
