Solana Program Development is the practice of writing smart contracts (called "programs" on Solana) using Rust and the Anchor framework. Solana programs operate differently from Ethereum contracts: they're stateless, use external accounts for storage, and leverage Solana's Proof of History consensus to enable high throughput and low latency. Solana programs power DeFi, NFTs, and other on-chain applications. The Solana ecosystem is growing rapidly and demand for skilled developers far exceeds supply.
