The bottom layer of digital currency is blockchain

1. In a narrow sense, blockchain is a kind of chained data structure that combines data blocks in chronological order in a way of sequential connection, and it is a distributed account book that can not be tampered with and forged by cryptography. In a broad sense, blockchain technology is a new distributed infrastructure and computing paradigm, which uses blockchain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contract composed of automated script code to program and operate data
nowadays, the mainstream digital currencies are basically developed based on blockchain technology. Blockchain is the underlying technology of digital currency. The domestic tea based digital currency Puyin is developed based on blockchain technology.

2. Since 2008, Nakamoto has proposed bitcoin, a peer-to-peer cash trading system. Since then, it has entered the eyes of the world.

3. Digital currency is represented by blockchain 1.0, mainly bitcoin; As a virtual currency system, the total amount of bitcoin is limited by network consensus protocol, and no indivial or institution can change or modify the supply and transaction records. Therefore, after years of successful operation of bitcoin network, blockchain is the underlying technology to support the operation of bitcoin, Its essence is a very clever distributed shared ledger and point-to-point value transmission technology. It will have a great potential impact on finance and even all walks of life
blockchain 2.0 technology application represented by smart contract
the era of blockchain 3.0 has come. Behind the operation of all walks of life, we can see the mode of collaborative operation of blockchain. Therefore, blockchain is bound to widely and profoundly change the way of human life, so the whole life service will enter the era of blockchain. In the process of Internet development, blockchain + physical instry, blockchain e-commerce and blockchain community operation can be applied to blockchain technology.

4. Blockchain and digital currency are not a concept
blockchain is a decentralized database, which is a series of data blocks generated by using cryptographic methods. This is a very big concept and has a wide application prospect
digital currency is an unregulated and digital currency. It is just an application of blockchain technology, which is based on the birth of blockchain technology
to put it simply, digital currency and blockchain are closely linked, and blockchain is the bottom technology and the most important technical means of digital currency. The most successful practice of blockchain is innovation in the field of currency.

5. The underlying technology of bitcoin is blockchain, which is equivalent to the Internet now. Anyone can use the Internet. The Internet is a basic instry. At present, many domestic business tycoons are from the Internet instry. In the future, blockchain will also proce many business tycoons
there is a certain relationship between the digital currency that the central bank plans to issue and the underlying technology blockchain of digital cryptocurrency, which may be applied to the blockchain technology. The central bank also developed the digital currency inspired by bitcoin. Does the Yinying China platform also use the blockchain technology, taking the lead in introcing digital currency and blockchain into the crowdfunding instry.

6. Hello
because the blockchain technology is the underlying technology of bitcoin at the beginning, and it is only when people realize bitcoin that they realize the development of blockchain. Up to now, the instry of blockchain + is still exploring, and there are not many real applications, mainly in the application of bitcoin, but it may not be in the future
hope to adopt
Mr. Yuan Wang is engaged in the development of digital asset blockchain system. If necessary, you can search "Mr. Yuan Wang" on the Internet for detailed communication.

7.

At present, the most successful application of blockchain technology is the digital currency represented by bitcoin, and blockchain also benefits from the deeper development of digital currency

instry insiders said that if a wants to send a bitcoin to B, it first needs to send a transaction request to the blockchain network, provide the addresses of a and B as well as the number of bitcoins sent, and at the same time use the private key to digitally sign the sent information to prove its identity to B. After the information is sent, the miner needs to determine the uniqueness of the transaction, the legitimacy of the address involved in the transaction, the authenticity of the digital signature and the correctness of the number of bitcoins after receiving the information sent by A

after successful verification, the transaction will be added to the block, and each block contains all the transactions in the past ten minutes. Generally speaking, each transaction must be confirmed six times before it can be recognized as a legal transaction on the blockchain. Finally, the block is chained, the transaction is completed, and B receives 1 bitcoin
