Overview
Solana is a Layer 1 built for high throughput. It uses Proof of History, targets sub-second finality, and keeps fees low relative to many other smart-contract chains.
Highlights
- Proof of History plus parallel execution (Sealevel). The design target often cited for the chain is 65,000+ transactions per second.
- A typical fee is well under 0.001 USD, and confirmation is often around 400 milliseconds.
- It has active DeFi, meme-token launch activity, and mobile Web3 apps.
Token model
SOL pays fees, is staked to validators, and is used in governance. Issuance decays from an initial inflation schedule, and part of the transaction fee is burned.
FAQ
Why is Solana fast?
Proof of History gives validators a shared clock, so they do not wait on a separate time vote for every block. A pipelined architecture processes work in parallel.
