OP 堆疊

The OP Stack is a standardized, open-source modular software stack designed to simplify the creation and operation of Layer 2 blockchains secured by Ethereum. It provides a comprehensive foundation for developers and organizations to build scalable, low-cost, and fast Layer 2 solutions that inherit Ethereum's security guarantees. The stack includes components for execution, consensus, data availability, and settlement, enabling users to deploy their own chains or build applications on existing OP Stack networks.

Intended for blockchain developers, infrastructure operators, and enterprise teams, the OP Stack supports full Ethereum Virtual Machine (EVM) compatibility, allowing seamless integration with existing Ethereum tooling and smart contracts. Its modular design allows customization of components to fit specific project requirements. Developers can start by building decentralized applications on OP Stack chains or launch their own Layer 2 chain using the stack. Node operators can also run infrastructure nodes to support the network.

Key differentiators include its open-source nature, modular architecture, and direct security inheritance from Ethereum mainnet. This contrasts with other Layer 2 solutions that may rely on different security models or proprietary technology. The OP Stack also emphasizes interoperability through features like cross-chain messaging and account abstraction. Adoption is driven by Optimism's mainnet and testnet deployments, with a growing ecosystem of tools, tutorials, and community support.

Getting started involves setting up a development environment with Node.js and popular Ethereum frameworks like Hardhat or Foundry, obtaining test ETH from the Superchain Faucet, and deploying smart contracts. Comprehensive documentation and tutorials guide users through building apps, running nodes, and deploying chains. The OP Stack continues to evolve with ongoing protocol improvements and community contributions.
