The remitter will pay bitcoin directly to the other party according to the address of the payee through the computer or smart phone

after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed

the bitcoin peer-to-peer network stores all transaction history in the "blockchain". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. In fact, blockchain is a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history

extended data

users can buy bitcoin, and at the same time, they can "mine" bitcoin by using computers to perform a large number of calculations according to the algorithm. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins

from 2012 to 2014, bitcoin swept the world, and graally formed the "virtual currency" instry chain represented by bitcoin. This is a change in the financial instry and a new proct of the combination of the financial instry and the Internet.

4. Three paths can be cut into the blockchain from the bitcoin instrial chain: core personnel start their own businesses, mainly represented by onchain (ant shares system for non listed equity registration, settlement, etc.), Taiyi technology; 2) Bitfury, a typical representative of bitcoin instrial chain company, is a blockchain service provider transformed from miner chip proction. It is suggested that bitquan, Jianan Yun and bitmainland, the three major miner chip manufacturers in China, should be paid attention to. In addition, it is suggested to pay attention to the exchange's fire coin network and BTCC; 3) Cooperate with fintech listed companies to promote the application of blockchain through technology authorization or direct merger and acquisition. It is suggested to pay attention to the layout progress of Feitian integrity, radio and television express, win win win, Royal Bank, Westone, sinyada and Hang Seng electronics in blockchain technology.

5. 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

according to the notice on preventing the financing risk of token issuance, there is no approved digital currency trading platform in China. According to China's digital currency regulatory framework, investors have the freedom to participate in digital currency transactions at their own risk

6. The core code of the blockchain of blockchain technology operates on the server side, decouples the bottom part of the blockchain code (P2P network, consensus algorithm, data storage, etc.) from the wallet part (address management, encryption algorithm, transaction control, etc.), and deeply optimizes the whole blockchain code. This is how the bitbox system is transplanted to the mobile terminal. Make it better adapt to mobile phone hardware and network performance, improve the stability and reliability of blockchain operation, but also bring greater security

8. Coin circle mining refers to that miners use mining machines, consume electricity, calculate algorithm problems (solve the problem of workload proof mechanism with a certain workload to manage bitcoin Network - confirm transactions and prevent double payment), work out standard answers (obtain the right to generate blocks and successfully generate new blocks), And the process of getting a certain amount of monetary reward (bitcoin)
because this process is similar to the gold mining process in real life, it is called "mining".
