The relationship between Bitcoin, blockchain, and Web3 Many friends often struggle to distinguish the relationship between Bitcoin, blockchain, and Web3. Today, we will use easy to understand language to thoroughly understand the technical logic, development and evolution, and practical applications between these three. Core relationship Blockchain (Technical Foundation) Blockchain is a decentralized, transparent, and secure distributed ledger technology, where data is linked in block form in chronological order and cannot be tampered with. It is the underlying technology of Bitcoin and Web3. Bitcoin (Pioneer Application) Bitcoin is the first successful application of blockchain, a decentralized digital currency that relies on blockchain to record transactions. Its significance lies in verifying the feasibility of blockchain and promoting the popularization of technology. Web3 (Internet upgrade) Web3 is a new generation of Internet based on blockchain, which emphasizes users' sovereignty over data and assets (decentralization). It extends blockchain technology from currency to a wide range of fields such as finance, social, identity, gaming, and more. Analogical understanding Blockchain: Like an immutable ledger, it records all transactions and data. Bitcoin: The first page in the ledger that records transactions of a decentralized currency. Web3: The future Internet based on this account book, users can not only read and write, but also "own" data and assets. reality application Blockchain: supply chain traceability, medical data management, judicial evidence storage. Bitcoin: Value storage, cross-border payments, safe haven asset. Web3： DeFi: Uniswap, Aave (lending, trading). NFT: Digital Art (Beeple), Game Assets (Axie Infinity). DAO: Decentralized Governance (MakerDAO). Other: On chain social networking (Lens Protocol), decentralized storage (Filecoin). To summarize: If blockchain is the technology, Bitcoin is the first application, and Web3 is the future of this technology. Bitcoin was born from blockchain technology, validating the possibility of a "decentralized currency". And Web3 shows us that the future is not just about currency, but also about decentralized social, content, and identity. You can also understand it this way: blockchain is an encryption technology, Bitcoin is a derivative asset of blockchain, and web3 is the commercial form of blockchain. BTC Web3
