Blockchain
is a distributed ledger technology characterized by decentralization, immutability, and transparency. It ensures that all nodes in the network reach consensus on data addition through consensus mechanisms.
1. Function: Blockchain is a foundational technology that provides a secure, transparent, and decentralized infrastructure that can be used to record transactions or other data.
2. Application Scenarios: Not just cryptocurrency, but also supply chain management, data storage, identity verification, smart contracts, etc.
3. Relationship with Bitcoin: Bitcoin is the first application of blockchain technology, and blockchain is the core technology that supports Bitcoin's operation.
Bitcoin
is a digital currency designed for peer-to-peer value transfer, decentralized, and not relying on any central authority (such as banks).
1. Features
Decentralized, Limited Supply, Blockchain Driven: Bitcoin's transaction records are maintained through blockchain technology.
2. Relationship with Blockchain: Bitcoin is the first successful application of blockchain technology, providing a distributed ledger that records all Bitcoin transactions.
3. Relationship with Web3: Bitcoin can be seen as part of the Web3 ecosystem, but its functionality focuses more on value storage and payment.
Web3
is a new decentralized internet form based on blockchain technology. It aims to build a new type of internet where users can directly control their data, identity, and assets through blockchain, cryptocurrency, and decentralized protocols.
1. Features
Decentralization
User Ownership: Users control their own data and digital assets, for example, managing assets directly through cryptocurrency wallets.
Smart Contracts: Automated operations without intermediaries are achieved through smart contracts on the blockchain.
Economic Incentives: Users are encouraged to participate and contribute through token economic models.
2. Relationship with Blockchain: Blockchain is the technological foundation of Web3, and applications in Web3 (such as decentralized finance and NFTs) rely on the distributed ledger and smart contracts of blockchain.
3. Relationship with Bitcoin: Bitcoin is part of the Web3 ecosystem, but Web3 encompasses a broader scope, while Bitcoin mainly focuses on the functionality of digital currency.
Relationship among the three
Blockchain is a cryptographic technology, Bitcoin is a derivative asset of blockchain, and Web3 is the commercial form of blockchain.
To illustrate:
Blockchain is "electricity", providing the fundamental energy;
Bitcoin is the "light bulb", the first successful application of electricity;
Web3 is the "smart grid", a more complex and extensive system based on electricity.
