1. First of all, we can take a look at the official website explanation of blockchain technology. In a narrow sense, blockchain is a kind of chain data structure that combines data blocks in a sequential way according to the time sequence, and it is a distributed account book that can not be tampered with and forged by means of cryptography
broadly speaking, 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
as we all know, blockchain technology is an independent underlying architecture from bitcoin system. From the perspective of architecture model, it is a set of distributed ledger, which is naturally used for bookkeeping
in the blockchain technology, if you want to generate accounting records, you need to have the transaction and flow of funds. Therefore, in the initial blockchain technology, the cryptocurrency corresponding to the main network is used as circulation goods, and the circulation transaction records of cryptocurrency between the accounts of the main network of the blockchain will be recorded on the main network
different from other transaction record databases, transaction records on the main network of blockchain technology will be recorded on all block nodes (i.e. all data blocks) in the main network, which is the so-called decentralization principle. That is to say, in blockchain technology, there is no central database to store all records, Every block on the chain has the transaction data of the whole chain, that is to say, every data block is the center
another feature of blockchain technology is that it can't be tampered with, because every transaction on the blockchain will be recorded in all blocks on the chain, so no single data block can change the record. Even if you change it, all other data blocks will also record real data, and each group of data can be traced back to the first time
because of these characteristics of blockchain technology, after the advent of bitcoin, blockchain has also attracted a lot of attention, and many people also began to want to use blockchain technology to make a centerless, traceable and unchangeable data, so as to ensure the credibility of the data
however, blockchain technology also faces many problems, such as single application scenario, non modifiable original error data, non recoverable currency stolen by hackers, etc.

2. 99% of them are deceiving. It's deceiving to say how much it will appreciate. It's just a technology, its application is valuable.
3.
Anti counterfeiting, such as frog coin and Weilian the source and process of frozen food monitoring of final procts such as imported milk powder and luxury goods: red wine, bags and refrigerators, because it is impossible to cheat by writing into the blockchain Back modification is being implemented or has been implemented (only the chain's partners are very strong)
smart contract or intellectual property rights, such as publishing a song. In the blockchain, you own the song, use the smart contract to sell and protect the property rights, such as Neo and Ethereum. Game development or program development: for example, cryptokitties are free to breed and trade different kinds of cats without age or rarity (the closer the age is, the more expensive it is)
the evolutionary version of ICO IPO raised $40 billion in 2017, which is the securities of any company or indivial to support its development of e-money Platform (polymeth)
free trade of game items under development
4. Blockchain technology is considered as the "golden key" to solve the social credit problem by technical means
I may have heard the saying "artificial intelligence is proctivity and blockchain is proction relationship", which also shows the development potential of regional chain
on the public blockchain, there can be no digital currency. So regional chain fire, digital currency is the same, and the Internet fire is a reason.

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".
