The world's most complete blockchain jargon you'll regret not reading!

When you first enter the chain, many of you may be confused by the various technical terms, so I have compiled 30 of the most common blockchain terms here for your reference.

1、Blockchain - Blockchain

Blockchain is a new application model of computer technology such as distributed data storage, peer-to-peer transmission, consensus mechanisms, and cryptographic algorithms. is a shared distributed ledger in which transactions are permanently recorded through additional blocks.

2. Block head

Inside the block header stores the block's header information, containing the hash of the previous block (PreHash), the hash of the body of this block (Hash), and the timestamp (TimeStamp), among other things.

3. Block - block

In the Bitcoin network, data is permanently recorded in the form of files, which we call blocks. A block is the set of records for some or all of the latest bitcoin transactions and is not recorded by other previous blocks.


Oracle bridges the gap between it real world and the blockchain by providing data to smart contracts.

5. Cryptocurrency

Cryptocurrency is a type of digital currency (or virtual currency). It is a medium of exchange that uses cryptographic principles to secure transactions and control the creation of trading units.

6. Decentralization

Decentralization is a phenomenon or structure that must occur or exist in a system with many nodes or in a swarm with many individuals. Node-to-node effects can form non-linear causal relationships through the network.

7. Node - node

A copy of the ledger operated by a participant in the blockchain network.

8. Pow - proof of workload

Proofof Work, which is how much cryptocurrency you get, depends on the amount of work you contribute to mining, and the better your computer performs, the more mines will be distributed to you.

9. PoS - Proof of Interest

Proofof Stake, a system that distributes interest based on the amount and duration of your cryptocurrency holdings, is a POS model in which your "mining" earnings are proportional to the age of your coins, independent of the computing performance of your computer.

10. P2P - peer-to-peer networks

That is, a peer-to-peer computer network, a distributed application architecture that distributes tasks and workloads among peers (Peers), is a form of networking or network formed by the peer-to-peer computing model at the application layer.

11. Timestamp

A timestamp is a string or encoded message used to identify the date in time when it was recorded. The international standard is ISO 8601.

12. Smart contracts

A smart contract is a computer protocol designed to disseminate, validate or enforce a contract in an informational manner. Smart contracts allow for trusted transactions without a third party, which are traceable and irreversible.

13. Superbook

Hyperledger is an open source project launched by the Linux Foundation in 2015 to advance blockchain digital technology and transaction validation. Assist organizations in scaling, building industry-specific applications, platforms and hardware systems to support members' respective transactional operations by creating common distributed ledger technology.

14. DAO - Decentralized Autonomous Organization

It can be thought of as a company that operates without any human intervention and gives all forms of control to an unbreakable set of business rules.

15. DistributedLedger - the distributed ledger

The data is stored through a network of distributed nodes. A distributed ledger is not required to have its own currency; it may be licensed and private.

16、PrivateKey--private key

A private key is a string of data that is a token that allows you to access a specific wallet in your wallet. They are hidden as passwords, except for the owner of the address.

17、PublicKey - public key

is present in pairs with the private key, and the public key can count the address of the coin, and therefore can be used as a credential to own the address of this coin.

18、Wallet - Wallet

A file containing the private key. It usually contains a software client that allows access to view and create transactions for the particular blockchain the wallet is designed for.

19. Full node

Full nodes are nodes that have a complete blockchain ledger. Full nodes need to occupy memory to synchronize all blockchain data, can independently verify all transactions on the blockchain and update data in real time, and are mainly responsible for the broadcast and verification of blockchain transactions.

20. Mining - mining

Mining is the nickname for the exploration method of acquiring bitcoins. The process of using computer hardware to calculate the location of coins and acquire them is called mining.

21. Miners

A computing device or software that attempts to create blocks and add them to the blockchain. In a blockchain network, when a new valid block is created, the system generally automatically gives the block creator (miner) a certain number of tokens as a reward.

22. Mining pools

is a fully automated mining platform that enables miners to contribute their respective computing power to mine together to create blocks, receive block rewards, and distribute profits based on the percentage of computing power contributed (i.e. miners access the pool - provide computing power - receive revenue).

23. Public chains

A fully open blockchain is one that anyone can read, anyone can send transactions and have them validly confirmed, anyone in the world can participate in maintaining the system, and anyone can read and write data through transactions or mining.

24. Private chains

Write access to a blockchain that is only for a particular organization or a specific few objects. Read access can be made available to the public, or restricted to any degree.

25. Main link

The term masterchain derives from mainnet (as opposed to testnet testnet), the officially live, independent blockchain network.

26. Affiliate chain

The consensus mechanism is a blockchain controlled jointly by a designated number of institutions.

27. Side chains

Wedged sidechain technology (pegged sidechains), which will enable the transfer of bitcoin and other digital assets between multiple blockchains, meaning users will be able to access new cryptocurrency systems while still using the assets they already have.

28. Hard bifurcation

A permanent disagreement in the blockchain occurs, and a hard fork usually occurs when a new consensus rule is released and some of the nodes that have not upgraded cannot verify the blocks produced by the nodes that have upgraded.

29. Soft bifurcation

When the new consensus rule is released, nodes that have not upgraded will produce illegitimate blocks because they are unaware of the new consensus rule under which a temporary fork will be created.


SHA-256 is the cryptographic algorithm used by some of Bitcoin's listed digital currencies. However, it uses a lot of computing power and processing time, forcing miners to form mining pools to generate revenue.
