1 min read

Pronunciation

[proof-of-aw-thor-i-tee awr-uh-kl]

Analogy

Like a board of certified experts whose signed statements everyone trusts without further verification.

Definition

An model where a fixed set of authorized nodes—rather than decentralized —sign and submit data, trading trust assumptions for higher throughput and simplicity.

Key Points Intro

oracles rely on vetted authorities for fast, simplified data delivery.

Key Points

Authorized signers: Known entities with on‑chain identity.

Fast finality: No multi‑party aggregation needed.

Simplified governance: Authority set managed by ACL.

Use cases: Private networks, regulated environments.

Example

A consortium issues price updates via three approved nodes; each update accepted if signed by any one authority.

Technical Deep Dive

contract stores `authorities[]`. On `submit(data, sig)`, contract recovers `sig` signer and checks membership in `authorities` before accepting.

Security Warning

Centralization risk; compromise of any authority undermines feed integrity.

Caveat

Not suitable for censorship-resistant public applications.
