What are the basic technologies of blockchain?

Blockchain basic technologies include: distributed ledger: decentralized storage of transaction records. Consensus mechanism: Ensure that all nodes reach a consensus on transaction status. Cryptography: Protecting data integrity and security. Smart contracts: automatically execute transactions to ensure fairness and transparency. Other technologies: zero-knowledge proof, sharding, and distributed hash tables to improve scalability and security.

Blockchain Basic Technology

Blockchain is a revolutionary technology that provides solutions for secure, transparent and efficient transactions. The basic technologies of blockchain include:

Distributed Ledger

• Blockchain is a distributed ledger in which transactions are recorded on multiple nodes.
• This eliminates the risk of single points of failure and ensures data remains safe and secure on the network.

Consensus Mechanism

• The consensus mechanism is a method to ensure that all nodes reach a consensus on the transaction status.
• Popular methods include Proof of Work (PoW), Proof of Stake (PoS), and Byzantine Fault Tolerance (BFT).

Cryptography

• Cryptography is used to protect data on the blockchain.
• Hash functions, digital signatures and encryption are used to ensure the integrity and security of transactions.

Smart Contracts

• Smart contracts are programs stored on the blockchain.
• They execute predefined codes that can automate transactions, ensuring fairness and transparency.

Other Technologies

• Zero-Knowledge Proof (ZKP): A way to prove authenticity without revealing sensitive information.
• Sharding: A technology that divides a blockchain network into smaller parts to improve scalability.
• Distributed Hash Table (DHT): A distributed data structure that efficiently stores and retrieves data between nodes.
