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. Blockchain is characterized by decentralization, trust, collective maintenance and reliable database
for example, Sunzi asked Li Zi to borrow 100 yuan, but Li Zi was afraid that he would default, so he asked the village head to do notarization and add the account. This is called centralization. But if you don't ask the head of the village, you can shout "I'll lend my grandson 100 yuan! Please put it in the account book. "This is called decentralization. In the past, the village head was highly respected and had a good command of the accounts of the whole village. Everyone kept their money with him. This was the past trust in centralization. Now, everyone is worried that the village head will secretly misappropriate everyone's money. What should we do? So everyone sent an account book to everyone. Anyone who transfers money between them releases information through the loudspeaker. After receiving the information, everyone records the transaction in their own account book. This is called decentralization. With distributed ledgers, it doesn't matter if Lao Zhang or Lao Li's ledgers are lost, because Lao Zhao, Lao Ma and other families have ledgers
digital currency is abbreviation of digital currency. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy. Blockchain technology service upgrade technology

3. The two complement each other. In fact, chain and currency are inseparable. Blockchain technology has spawned digital currency, and digital currency has expanded the application of blockchain. At present, the most successful digital currency is bitcoin. If you want to invest, you can open an account at okex bitcoin exchange and buy it with wechat. If you are not clear, please ask at any time
4. 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.

5. Blockchain is an emerging instry, which has been highly valued by all countries. It is called the fourth instrial revolution and will have an immeasurable impact on society. Blockchain is the literal translation of block and chain. Each block stores the transaction data within a specified time, and forms a non tamperable, all staff shared distributed ledger through cryptography
digital currency and virtual currency are actually different names. They are tokens issued based on blockchain technology. Behind them are a series of computer-generated complex codes. At present, there are thousands of digital currencies in the market. The safest and most powerful digital currency is bitcoin
digital currency is also a high-risk and high return investment proct, through appropriate investment strategies, you can get rich returns. If you have spare money, you might as well put some of it into the digital currency. There will be unexpected surprises.

6. 1. Blockchain is an account book for recording digital currency transactions
taking bitcoin as an example, it does not have an entity form, but exists in a special account book. All bitcoin transactions are recorded in the ledger. Through the transaction records, we can calculate the number of bitcoins owned by each user. If a person owns bitcoin, it means that he can find the relevant transaction records in the ledger
the ledger mentioned here is a software that we can download from bitcoin's official website, and the underlying technology used in this software is blockchain. In order to facilitate understanding, we usually say that blockchain is the ledger
the reason why blockchain is used as the underlying technology of ledger is to realize the feature of digital currency decentralization. It can be said that the starting point of a series of problems and solutions of digital currency comes from decentralization
2. Blockchain is a technology to ensure the safe use of digital currency. As we all know, blockchain technology has the characteristics of encryption and non tampering, which can rece the probability of errors in the use of digital currency to 0. Because digital currency requires higher encryption, it must be supported by blockchain technology. At present, not only many instries in China are using blockchain technology, but also many foreign countries are actively using blockchain technology.
