Blockchain is a distributed and decentralized digital ledger technology. Its core principles include: 1. Distributed ledger ensures that data is stored simultaneously on all nodes; 2. Encryption technology, linking blocks through hash values to ensure that data is not tampered with; 3. Consensus mechanisms, such as PoW or PoS, ensure that transactions are agreed between nodes; 4. Decentralization, eliminating single point of control, enhancing censorship resistance; 5. Smart contracts, protocols for automated execution. Cryptocurrencies are digital assets issued based on blockchain. The operation process is: 1. The user initiates transactions and signs digitally; 2. The transactions are broadcast to the network; 3. The miner or verifier verifies the validity of the transaction; 4. Multiple transactions are packaged into new blocks; 5. Confirm the new zone through consensus mechanism

Smart contracts are automatic execution programs stored on blockchains. The core is to implement the "if... then..." logic through code to execute protocols in a decentralized and tamper-free way. 1. Write code: define contract logic using languages such as Solidity; 2. Compile: convert the code into machine-readable bytecode; 3. Deploy: publish the bytecode to the blockchain through transactions and generate a unique address; 4. Trigger execution: When the preset conditions are met, the contract will run automatically; 5. Record the result: All operations are permanently recorded on the chain to ensure transparency and verifiability. It solves the trust, efficiency, cost, transparency and execution risks in traditional protocols, and is widely used in DeFi, supply chain, copyright management, voting, insurance and gaming fields.

Through its Turing-complete smart contracts, EVM virtual machines and Gas mechanisms, Ethereum has built a programmable blockchain platform beyond Bitcoin, supporting diversified application ecosystems such as DeFi and NFT; its core advantages include a rich DApp ecosystem, strong programmability, active developer community and cross-chain interoperability; it is currently implementing consensus transformation from PoW to PoS through the upgrade of Ethereum 2.0, introducing beacon chains, verifier mechanisms and punishment systems to improve energy efficiency, security and decentralization; in the future, it will rely on sharding technology to realize data sharding and parallel processing, greatly improving throughput; at the same time, Rollup technology has been widely used as a Layer 2 solution, Optimistic Rollup and ZK-Rollu
