AI translates the explanation and quiz text while preserving code and answer scoring.

Native programs achieve the lowest compute unit consumption and smallest binary sizes because they omit Anchor's discriminator routing, auto-generated IDL metadata, and heavy macro scaffolding. Anchor prioritizes developer velocity and built-in security guarantees.

How to study this topic

1. Read the explanation once end to end, skipping the code.
2. Re-read the code snippets and say out loud what each line does.
3. Answer the quiz without scrolling back — that is the real check.
4. Read every explanation, even for the answers you got right.

Scoring

· Up to 30 XP from quiz accuracy.
· +15 XP for a perfect first attempt.
· +5 XP while a 3-day streak is running.
· 75% or higher marks the topic complete.

1. What is the primary trade-off of using native Rust over Anchor?
Lower compute unit overhead and smaller binary size vs manual security validation and no automatic IDLNative Rust is easier to readAnchor runs on EVMNative Rust has no rent
2. Why do high-frequency AMMs or orderbooks sometimes choose native Rust or Pinocchio over Anchor?
To save critical compute units (CUs) on every transaction executionBecause Anchor is banned on mainnetAnchor does not support tokensNative Rust is written in C
