Tufei block chain mining
In 2009, bencong invented bitcoin, and set that there are only 21 million bitcoins. By participating in the proction of blocks and providing proof of work (POW), he can get the reward of bitcoin network. This process is mining
the concept of "mining" comes from the existing concepts in our real economic life, such as gold mining and silver mining. Because minerals are valuable, it drives people to pay labor to dig
another important point of bitcoin mining is that the miners who participate in mining recognize the value of bitcoin, and some of them are willing to spend money in the bitcoin market. Therefore, the mining of bitcoin is meaningful
extended data
currency characteristics of bitcoin
1, decentralized
bitcoin is the first distributed virtual currency, and the whole network is composed of users without central bank. Decentralization is the guarantee of bitcoin's security and freedom
2, bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3, exclusive ownership
controlling bitcoin requires a private key, which can be stored in any storage medium in isolation. No one can get it except the user himself
4, low transaction cost
bitcoin can be remitted free of charge, but in the end, about 1 bitfen transaction fee will be charged for each transaction to ensure faster transaction execution
5, no hidden cost
as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6, cross platform mining
users can explore the computing power of different hardware on many platforms
I had done a USB mining project before, and the boss cheated a lot of money. It's also working with a lot of big companies.
in fact, their real idea is to know how to make money. After all, how much has bitcoin gone up in recent years when all kinds of information came out on the Internet, and to what extent has blockchain become popular today, Internet companies in all halls have joined in. As ordinary people, they also want to splash in this "pond"
so what is blockchain< In a broad sense, blockchain technology is to use blockchain data structure to verify and store data, use distributed node consensus algorithm to generate and update data, and use cryptography to ensure the security of data transmission and access It is a new distributed infrastructure and computing paradigm to program and manipulate data by using smart contracts composed of automated script code
in short, blockchain is a decentralized distributed ledger database. Decentralization is different from the traditional way of centralization. There is no center, or everyone is the center; Distributed ledger database means that the recording method is not only to store the ledger data in each node, but also to share and the data of the whole ledger synchronously. At the same time, blockchain also has the characteristics of disintermediation and information transparency
let's give an example. For example, in our usual online shopping, after placing an order, our money will be transferred to the intermediary platform of the third-party payment agency. After the seller delivers the goods and the buyer confirms the receipt of the goods, the buyer will inform the payment agency to transfer the money to the seller's account
however, the transaction mode supported by blockchain technology is different. Buyers and sellers can trade directly without any intermediary platform. After the transaction between the buyer and the seller, the system publishes the transaction information in the form of broadcast, and all hosts receiving the information record the transaction after confirming that the information is correct, which means that all hosts have done data backup for the transaction. If there is a problem with the orders proced by this machine, its data information will not be affected, because there are countless machines backing up data at the same time
when it comes to blockchain, we have to mention bitcoin, as if you don't understand anything without putting the two together
in fact, although blockchain is a blockchain and bitcoin is bitcoin, most of the people concerned are
concerned about bitcoin, and not many people are concerned about blockchain. Even if he says that he is concerned about the chain, in fact, that is to make do with the excitement. What the other party is more concerned about is which kind of currency makes more money. How can I join in
in fact, what I want to say is that you don't have to catch up with every outlet. If you don't catch up with the stock market, we media, wechat business and artificial intelligence, so will the blockchain. New procts will soon replace it
What's the role of blockchain in making people so obsessed? Let's take the above shopping example to illustrate that the so-called bilateral transactions are not absent now, but they are both bilateral transactions. What if one of them does not deliver the goods to you after receiving the money, or if he does not accept the account after receiving the money
How can blockchain solve this problem
it's also a transaction, but in the process of transaction, everyone knows that the other party has given you the money, and you can't deny it. In the final analysis, it's a matter of credit value
what can blockchain bring us? Once there was such a news in the society that how to prove that your mother is your mother. Even if we have the ID card account book in our hands, we still need a government agency to identify it, which is cumbersome
with the help of the regional payment chain, we can establish credit with low cost through mathematical principles rather than centralized credit institutions. In this way, our birth certificate, household register and real estate certificate can be verified on the blockchain. Your mother is your mother's problem
another example is the food safety problem that has been implemented at present, and the rookie tmall Jingdong has started to use it. With the help of blockchain technology, a reliable mechanism has been established for all transactions, which enables procers, suppliers, processors, distributors, retailers, regulators and consumers in the food chain to obtain the source and status information of food at any time, so as to facilitate the tracking of contaminated food, accelerate the removal of problem food from shelves, and effectively prevent the spread of food safety problems
when consumers buy food, they can easily see where the food they eat comes from, how long it has been proced, and what fertilizer they have applied. For the arrival of blockchain, whether we are ready or not, we still have to see if we are not ready
