What is the SVM?

The Solana Virtual Machine is the execution engine of the Solana blockchain. Whenever you send tokens, buy an NFT, or use a DeFi app, the SVM runs the code behind that transaction and updates the blockchain's state. If the blockchain is a shared global computer, the SVM is the part that actually runs programs.

Programs, not "smart contracts"

On Solana, smart contracts are called programs. They're mostly written in Rust (C and C++ also work) and compiled into sBPF bytecode, which the SVM executes. Frameworks like Anchor make writing them much easier for beginners.

How it works

Account model: Code and data are stored separately. A program doesn't hold its own data; data lives in separate accounts. Every transaction declares up front which accounts it will read or write.

Parallel execution (Sealevel): Since accounts are declared in advance, the SVM can spot transactions that don't touch the same accounts and run them at the same time. This is a big reason Solana is fast and cheap.

Compute units: Each transaction has a compute budget. More work uses more compute units, and fees reflect that. This prevents programs from running endlessly.

SVM vs. EVM

Language: EVM uses Solidity; SVM uses Rust

Execution: EVM is mostly sequential; SVM is parallel

Data: EVM stores data inside each contract; SVM uses separate accounts

Fees: SVM fees are usually much lower

Beyond Solana

Anza, the core Solana developer team, has made the SVM a standalone, reusable component. Other projects, like app-specific chains and rollups, can now use it to power their own networks.

Where to start

Learn basic Rust, then the Anchor framework, then deploy a small program on Solana devnet, where you can experiment for free.
