Pronunciation

[awr-uh-kl rayt lim-i-ting]

Analogy

Like a turnstile that only allows a certain number of people through per minute to avoid overcrowding.

Definition

Mechanisms to cap the frequency or volume of data requests and submissions to an to prevent spam, abuse, or excessive consumption.

Key Points Intro

Oracle rate limiting protects networks from overload and malicious flooding.

Key Points

Per‑consumer caps: Limits on calls per address or API key.

Global throttle: Maximum updates per time window.

Exponential backoff: Increasing delays on repeated requests.

Quota tracking: Monitors usage in on‑chain state or off‑chain.

Example

An contract allows at most 100 price updates per hour; additional submissions revert.

Technical Deep Dive

Contract stores `lastWindow` and `count`. On `submit()`, if `block.timestamp – lastWindow > windowSize`, reset count; else increment and require `count = limit`.

Security Warning

Too strict limits can legitimate spikes; set thresholds based on usage patterns.

Caveat

logic adds cost; optimize with minimal writes.
