Blockchain is a new application model of distributed data storage, point-to-point transmission, consensus mechanism, cryptocurrency algorithm and other computer technologies. Is a shared distributed ledger in which transactions are permanently recorded by attaching blocks.
In the Bitcoin network, data is permanently recorded in files, which we call blocks. A block is a set of records of some or all recent Bitcoin transactions that have not been recorded by other prior blocks.
A copy of the ledger operated by participants in the blockchain network.
Decentralization is a phenomenon or structure that must appear or exist in a system with many nodes or in a group with many individuals. The influence between nodes will form nonlinear causality through the network.
The consensus mechanism is to complete the verification and confirmation of the transaction in a very short time by voting at special nodes. If several nodes with unrelated interests can agree on a transaction, we can assume that the whole network can agree on it.
“Unfortunately of Work” means how much currency you get depending on how much Work you contribute to mining, and the better your computer is, the more mines you get.
In POS mode, your “mining” returns are proportional to the age of your coin, not to the computational performance of your computer.
A smart contract is a computer protocol designed to propagate, validate, or enforce contracts in an informationized manner. Smart contracts allow trusted transactions that are traceable and irreversible without a third party.
A timestamp is a string or encoded information used to identify a recorded date and time. The international standard is ISO 8601.
Turing completion is the ability of a machine to perform any other computation that a programmable computer can perform.
Is an open source application that runs automatically, stores its data on a blockchain, incentives in the form of cryptocurrency tokens, and operates with protocols that display proof of value.
Think of companies that operate without any human intervention and surrender all forms of control to an unbreakable set of business rules.
A private key is a string of data that allows you to access a token in a particular wallet. As cryptocurrencies, they are hidden except for the owner of the address.
Is paired with a private key that calculates the address of the coin and thus acts as proof of ownership of that address.
A computing device or software that attempts to create a block and add it to the blockchain. In a blockchain network, when a new valid block is created, the system generally automatically rewards the block creator (mining machine) with a certain number of tokens.
Is a fully automatic mining platform, so that miners can contribute their computing power together to create a block, get a block reward, and according to the proportion of computing power contribution to the profit distribution (that is, the mining machine access to the pool – provide computing power – gain income).
A fully open blockchain is one that anyone can read, where anyone can send and validate transactions, where anyone around the world can participate in system maintenance, where anyone can trade or mine data to read and write.
A blockchain where write permissions are only available to an organization or to a specific few objects. Read permissions can be open or restricted to any extent.
The consensus mechanism is a blockchain that is jointly controlled by a number of designated institutions.
Wedged-in side-chain technology (pegged Sidechains) will enable the transfer of bitcoin and other digital assets across multiple blockchains, meaning users can access new cryptocurrency systems while using their existing assets.
Cross-chain technology can be understood as a bridge connecting various blockchains, and its main application is to realize Atom transactions between various blockchains, asset conversion, internal information exchange of blockchain, or solve problems of Oracle, etc.
A permanent divergence occurs in the blockchain, and a hard fork usually occurs when some unupgraded nodes are unable to verify the blocks produced by the upgraded nodes after a new consensus rule is published.
When the new consensus rules are issued, the nodes that have not been upgraded will produce illegal blocks because they do not know the new consensus rules, resulting in temporary forks.
Generally translated as “hash”, there are direct transliteration as “hash”. Simply put, it is a function that compresses a message of any length into a message digest of a fixed length.
The term “main chain” comes from the term “main network” (as opposed to “test network”), which is a standalone blockchain network that is officially live.

The three elements of Token
First, digital proof of equity, token must exist in the form of digital proof of equity, representing a right, a kind of inherent and intrinsic value;
The second is cryptocurrency. The authenticity, tamper-proof, privacy protection and other capabilities of the token are guaranteed by cryptocurrency.
The third is to be able to flow in a network, so that it can be verified anytime and anywhere.
