Web3 infrastructure is the foundation for a decentralized blockchain-based system. It includes technologies, tools and solutions required by developers to operate decentralized applications.
Protocol layer defines the fundamental underlying blockchain architecture. Layer 1 smart contract platforms include Bitcoin, Ethereum, Solana, Avalanche, Cosmos and others.
Category primitives layer operates on top of the protocol layer, and consists of interoperable building blocks that specialize at doing one specific task well. There are different specialized solutions for security, storage, analytics, communication, identity management, and other tasks.
Application layer combines different category primitives to create an application for end users that serves a specific use case. Axie Infinity, OpenSea and Matcha are some of the popular examples.
Access layer serves as a low-friction entry-point for users to access web3 ecosystem. Wallet, crypto exchange, activity aggregate and other providers serve this purpose.
