in the bitcoin network, data will be permanently recorded in the form of files, which we call blocks. A block is a set of records for some or all of the latest bitcoin transactions and is not recorded by other previous blocks
3. Node -- a of the ledger operated by the participants of the blockchain network
Decentralization is a phenomenon or structure, which can only appear or exist in a system with many nodes or in a group with many indivials. The influence between nodes will form nonlinear causality through the network5. Consensus mechanism
consensus mechanism is to complete the verification and confirmation of the transaction in a very short time through the voting of special nodes; For a transaction, if several nodes with unrelated interests can reach a consensus, we can think that the whole network can also reach a consensus
6. POW -- proof of work refers to how much money you get depends on the amount of work you contribute to mining. The better the performance of the computer, the more money you will be given
In POS mode, your "mining" income is directly proportional to your currency age, and has nothing to do with the computing performance of the computer8. Smart contract
smart contract is a kind of computer protocol which aims to spread, verify or execute the contract in an information way. Smart contracts allow trusted transactions without a third party, which are traceable and irreversible
9, time stamp

Privatekey - private key
a private key is a string of data that allows you to access a token in a specific wallet. As cryptocurrency, they are hidden except for the owner of the address

is paired with private key. The public key can calculate the address of the currency, so it can be used as a certificate to own the address of the currency
15, miner
try to create a block and add it to the computing device or software on the blockchain. In a blockchain network, when a new effective block is created, the system will automatically give the block creator (miner) a certain number of tokens as a reward
16. The mine pool is a fully automatic mining platform, which enables mining machines to contribute their computing power to mine together to create blocks, obtain block rewards, and distribute profits according to the proportion of computing power contribution (that is, mining machines access the mine pool - provide computing power - obtain income)
17, public chain
fully open blockchain, refers to anyone can read, anyone can send transactions and transactions can be effectively confirmed, people all over the world can participate in system maintenance, anyone can read and write data through transactions or mining

blockchain has permanent divergence. After the release of the new consensus rules, some nodes that have not been upgraded cannot verify the blocks proced by the upgraded nodes, and usually the hard fork will occur
23, soft forking
when the new consensus rules are released, nodes that have not been upgraded will proce illegal blocks because they do not know the new consensus rules, which will lead to temporary forking
24, hash -- hash value

Virtual currency is released by various network organizations, and there is no unified issuance and management standard

The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
blockchain is an important concept of bitcoin, which is essentially a disintermediated database, as well as the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block

1. The essence of virtual currency determines that it can't have the credit of money.
at the beginning of the emergence of money, it was a fixed commodity acting as a general equivalent, then there was an undervalued currency, and then it entered the era of dishonoured credit currency.

Because of hyperinflation, the credibility of the government can not be trusted, so the monetary system is no longer recognized by the people. There is no national credit behind the virtual currency. There is no confirmation and no reliable economic entity to support it. So its core value is not possessed
