System Architecture

A modular, scalable architecture designed for production Web3 applications. Each layer has clear responsibilities and interfaces.

Design Principles

Stateless Programs:

Programs are pure functions; state lives in accounts

Account-Based State:

All persistent data stored in on-chain accounts

Deterministic Execution:

Programs execute identically across all validators

Explicit Locks:

Read/write permissions enforced at the program level
