What encryption algorithm does blockchain use
hash algorithm is a cryptographic algorithm that can only encrypt, but not decrypt. It can convert any length of information into a fixed length string
this string has two characteristics:
1. Even if the input value changes only a little, the output hash value will be very different
2. Only exactly the same input value can get exactly the same output value
3. There is no rule between the input value and the output value, so the input value cannot be calculated by the output value. In order to find the specified output value, we can only use enumeration method: constantly change the input value to find the output value that meets the conditions
hash algorithm ensures that the results of bitcoin mining can not be deced reversely. Therefore, the miner's continuous operation is essentially brutally cracking the correct input value. Whoever finds the first one will get the bitcoin reward.
jinwowo group analyzes the functions of its hash algorithm as follows:
the hash value of the blockchain can uniquely and accurately identify a block. Any node in the blockchain obtains the hash value of the block through simple hash calculation, and the calculated hash value does not change, which means that the information in the blockchain has not been tampered with.
In today's era of high development of the Internet, we are using the Internet more and more frequently, which has become an indispensable and important tool in our life. In particular, the mobile phone used for Internet communication has been used as a medium. In today's era, we are using mobile payment more and more, There are more and more ways to move. So what is digital currency? What do you know about it{ But generally speaking, it is a form of money< p> Finally, for such a form of transaction, it's all for the convenience of our daily life, and it's also for serving our own broad masses of people, so we don't have to worry about the advantages and disadvantages of digital currency and mobile payment
there are about three kinds of currency in currency speculation. one is the base currency, which is similar to the representative of money. CNY and usdt Basic goods with value). One is the mainstream token, BTC, ETH (because of the national restrictions, the exchange can only trade in token, that is, take one kind of virtual currency to buy another kind of virtual currency, I don't know why.) The other is a variety of virtual currencies (commodities)
the purchase process is to first go to the exchange platform to find a personal seller with RMB to exchange for usdt, In the process of using usdt to exchange for the mainstream token BTC or eth used in purchasing various virtual coins, and finally using eth to purchase various virtual coins
A. base currency: CNY, usdt (exchangeable, need to be exchanged in good faith transactions with indivial buyers) B. mainstream token: BTC, ethc, virtual currency: all kinds of money, such as profit, need to be exchanged into usdt again, and then sold into CNY. Learn more about the coin circle

< / blockquote >experience: 1. Buy mainstream currency if you can't buy it. 2. If the new currency is not fried in January, it may become a banker to harvest leeks. 3. Just learned an experience, chasing up and killing down, meaning up do not buy, buy must be cut leeks If you have strength and value, you can hold it and wait for salted fish to turn over. 5. If the company is strong, the team is strong, and the executives are strong, you can pay more attention to it. Note: I don't understand the K line at all, and I don't understand the professional words, so I can only make a tentative decision on these purchase principles based on logical thinking
it is suggested that netizens should stay away from bitcoin and its related things if they don't understand bitcoin. This netizen can send me a private letter and tell me what you know. I will sort out and report on it.
