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. Digital currency is a virtual currency based on node network and digital encryption algorithm, which can be exchanged at will. The place of digital currency is just there. All the big domestic star traders, such as silktrader, fire coin, coin security, etc. The owner of digital currency can communicate with others on the platform through the matchmaking system, or directly purchase digital currency with legal currency through the legal currency channel.
4. 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.

5. There are many forms of bitcoin wallets, such as PC or mobile wallet clients, online web wallets, and even small notebooks (paper wallets) or brains (brain wallets) that record the private key of bitcoin. You can choose the right wallet according to your needs
bitcoin wallet can be divided into cold wallet and hot wallet according to the storage method of private key
01. A cold wallet is a wallet that can't access your private key on the Internet
cold wallets often rely on "cold" devices to ensure the security of bitcoin's private key, such as computers that are not connected to the Internet, mobile phones, small notebooks with private key addresses, etc. Cold wallet avoids the risk of hackers stealing the private key, but may face physical security risks, such as computer loss and damage
02. Hot wallet refers to the wallet that can access your private key on the Internet
Hot wallets are often in the form of online wallets. When using hot money package, it is better to set different passwords on different platforms and open secondary authentication to ensure the security of your assets
wallet is actually "a management tool for private key, address and blockchain data".

6. Market method, cost method and income method are three kinds of mining right evaluation methods, including replacement cost method, discounted cash flow method, equivalent investment sharing method, geological factor evaluation method, joint risk exploration agreement method, etc
mining right refers to the right that the mining right holder is given to carry out a series of activities such as exploration, development and mining of mineral resources, including exploration right and mining right
exploration right refers to the right to explore mineral resources within the scope and time limit specified in the exploration license obtained according to law. The legal document of exploration right is exploration license, and its economic significance lies in: (1) transfer the exploration right according to law to obtain income
(2) obtain geological data of mineral resources through exploration work, recover exploration investment and obtain income through transferring geological exploration report
(3) as the exploration right holder has the priority to obtain the mining right, after the exploration right holder has the priority to obtain the mining right and becomes the mining right holder, he can further invest capital and technology to carry out mining, so as to obtain greater investment income
mining right refers to the right of the mining right holder to exploit mineral resources within the scope and time limit specified in the mining right license obtained in accordance with the law. The legal document of mining right is the license of mining right. Its economic significance lies in that it can mine mineral resources within the specified scope and period and obtain excess return on investment. It is a kind of franchise within a certain scope and period
market method, cost method and income method are three kinds of mining right evaluation methods, including replacement cost method, discounted cash flow method, equivalent investment sharing method, geological factor evaluation method, joint risk exploration agreement method, etc
