1 BTC
2. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
3. Unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. 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. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million.
however, mining is very slow. It's only half a month since I got the crystal qualification. I only have 20000 crystals. The proction capacity is very low. The fastest speed is 3000K and the cache is 40g. In the last three days, it's about three or four thousand a day. The speed is fast in the evening, and almost no speed in the daytime
my home's 20m optical fiber is very close to the base station. The download speed is 3.7m/s, and the upload speed is about 2.4m/s.
The smallest unit of bitcoin is Cong
in addition to Cong, bitcoin also has other units: bitfen, millibit and microbit. Where 1 BTC = 100 CBTC = 1000 mbtc = 1 million μ BTC = 100 million
bitcoin is similar to e-cash of e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address
extended data:
starting from the essence of bitcoin, the essence of bitcoin is actually the special solution generated by a bunch of complex algorithms. A special solution is one of the finite solutions of a system of equations. Every particular solution can solve the equation and is unique
in the metaphor of banknotes, bitcoin is the number of the top word of a banknote. If you know the number of the top word on a banknote, you have the banknote. The process of mining is to constantly seek the special solution of the equation system through huge amount of calculation. The equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
