Mining is a nickname for the exploration method of acquiring bitcoin. Because of its working principle is very similar to mining minerals, so named. In addition, bitcoin explorers who do mining work are also known as miners
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes
then the bitcoin network will generate a certain amount of bitcoin as a reward to reward the person who gets the answer
extended data:
to be a miner, just "mine" bitcoin and search for 64 bit numbers by computer. By repeatedly decrypting with a computer, it competes with other gold miners to provide the number needed for the bitcoin network
if the computer can successfully create a set of numbers, it will get 25 bitcoins. Bitcoin is decentralized. It needs to create a fixed number of bitcoins per unit of computing time. It can get 25 bitcoins every 10 minutes
by 2140, the upper limit of bitcoin in circulation will reach 21 million. In other words, bitcoin system can be self-sufficient, which can be translated into coding to resist inflation and prevent others from sabotaging< br />
1: do a good long-term investment plan, the best way to dig is to dig by yourself, and the best way to dig is to buy or move bricks to make money
2: if the coin is empty, choose the one with less total amount (less amount and more appreciation space), and even large enterprises will not cut the coin with less amount (because the more the coin is cut, the less it is cut)
3: if you can dig and pre dig a little, even a big company can't do something that can dig. If you can dig, you'll get nothing Pre digging is used to cut leeks, so the currency with very little pre digging should be selected.)
Four: choose decentralized wallets instead of smart contracts. More than half a year of operation (so as to ensure the stability of the wallet)
Five: check the code, operation mode and service quality of the trading platform, and choose the one with good reputation, so as to prevent the platform from being stolen and running away. At present, there are few such platforms in China, and it takes time to understand them
six: don't look at landing scenes and publicity, because only empty coins need landing scenes to attract players to buy currency appreciation (depending on the amount).
2. Customer service: certification business, enjoy one-to-one exclusive services, exclusive standards, join the certification business community, etc
3. Applicable rules: Certified merchants are required to abide by the rules more strictly than ordinary merchants, and super merchants are required to abide by the rules more strictly than certified merchants
4. Scope of application: global businesses support foreign currency transactions (US dollar, Singapore dollar, etc.).
PSTN (public switched telephone network)
is a global voice communication circuit switched network, including commercial and government-owned
includes commercial and government-owned. It also refers to simple old fashioned telephone service (POTS). It is a collection of all circuit switched telephone networks since Alexander Graham Bell invented the telephone. Today, in addition to the final connection between the user and the local switchboard, the PSTN has been fully digitized technically
extended data:
the main components of PSTN network are as follows:
1. Transmission system: cable (cable, optical fiber) is the main, cable and wireless (satellite, ground and radio) are used alternately, and the transmission system transits from PDH to SDH and DWDM
2. Switching system: the switching equipment in the telephone office, the exchange, has been programmed and digitized graally, and the connection process is controlled by computer User system: including telephone, fax and other terminals, and a pair of wires used to connect them with the switch (called user loop). The user terminal has been graally digitized, multimedia and intelligent, and the user loop has been digitized and broadband Signaling system: in order to realize the communication between users, various control signals are provided between exchange offices, which are mainly call establishment and releaseaccess through PSTN:
dial up Internet / Intranet / LAN- Network interconnection between two or more LANs
Although PSTN has some problems in data transmission, it is still an irreplaceable networking medium (Technology). In particular, the application of xDSL technology and procts invented by Bellcore, which is based on PSTN, expands the development and application space of PSTN, making the networking speed between 9mbps and 52mbpsdigital currency generally refers to bitcoin, Leyte coin, dogcoin, decent and so on.
