The solution of bitcoin equation is the same

1. Block Tianyan: the concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity
on January 8, 2021, the price of bitcoin exceeded $40000.

2.

(1) Bitcoin was originally a kind of network virtual currency to buy real-life goods

(2) advantages:

< UL >

completely decentralized, without issuing institutions, it is impossible to manipulate the number of issues

anonymity, tax exemption and supervision free

robustness. Bitcoin is completely dependent on P2P network and has no distribution center, so it cannot be shut down externally

cross border

it's difficult for the cat to survive

< / UL >

(3) disadvantages:

< UL >

the vulnerability of trading platform

transaction confirmation takes a long time

the price fluctuates greatly

the public did not understand the principle, and the traditional financial practitioners resisted

3. The solution to the equation is mining, the transaction is block, and each address will not be repeated

4. Hub75, do you buy outdoors or indoors? It's OK to use SCM to proce a few simple characters. But if you want to have grayscale or something, SCM will not be able to proce characters. If you want to have more colors and less IO ports, you can't do it. If you want to play simply, you'd better buy lingxingyu's 801 receiving card, and the Gigabit network card will be good, Otherwise, it's really troublesome. If you want to find information, you can take a look at the website of Taiwan accumulation. There are Chinese information of 5020 or 5026 chips on it. Maybe your screen is not such a chip, but they are similar things. Just look at one. The information is easy to understand at noon!

5. Oil futures trading based on blockchain
blockchain is a technology, and the financial procts grafted on it are digital currency, such as bitcoin, lightcoin, Ethereum, etc. To be polite, blockchain oil futures trading should be a gimmick. To be polite, it's a liar.

6. When the global financial crisis broke out in 2008, someone used the pseudonym of "Nakamoto Tsung" to write a paper describing the mode of bitcoin. In 2009, bitcoin, which is not controlled by the central bank and any financial institutions, was born
bitcoin is a kind of "electronic currency", which is composed of a series of complex codes generated by computer. New bitcoin is manufactured through preset programs. With the increase of the total amount of bitcoin, the speed of new coin manufacturing slows down. Until 2140, the total amount of bitcoin reached the maximum of 21 million, and the total amount of bitcoin g out has exceeded 12 million
starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. And each special solution can solve the equation and is unique
in terms of RMB, bitcoin is the serial number of RMB. If you know the serial number of a banknote, you have the banknote.

7. There are mainly two kinds of bitcoin algorithms, which are elliptic curve digital signature algorithm and sha256 hash algorithm

elliptic curve digital signature algorithm is mainly used in the generation process of bitcoin public key and private key, which is the cornerstone of bitcoin system. SHA-256 hash algorithm is mainly used in the workload proof mechanism of bitcoin

the principle of bitcoin generation is the special solution generated by complex operation, and mining is the process of finding the special solution. However, the total number of bitcoin is only 21 million, and with the continuous mining of bitcoin, the more difficult it will be to proce bitcoin, and the cost of acquiring bitcoin may be higher than the price of bitcoin itself

the bitcoin block consists of a block header and the transaction list contained in the block. The size of the block header is 80 bytes, which is composed of 4-byte version number, 32 byte hash value of the previous block, 32 byte Merkle root hash, 4-byte timestamp (current time), 4-byte current difficulty value and 4-byte random number. A block header with a fixed length of 80 bytes is the input string used to prove the workload of bitcoin. Constantly change the random number in the block header, that is, the value of nonce, and do double sha256 operation on the block header after each change, and compare the result value with the target value of the current network. If it is less than the target value, the problem is solved successfully, and the workload is proved to be complete

the essence of bitcoin is actually the unique solution of a set of equations generated by a bunch of complex algorithms. Bitcoin is the first distributed virtual currency in the world, which has no specific distribution center. The network of bitcoin is composed of all users, because there is no center to ensure the security of data.

8. Bit B can be used as money because it can be exchanged with other currencies
