Horizon Documentation

Proof Infrastructure for Business Decisions

What is Horizon?

Horizon captures and seals business decisions as they happen, creating an immutable, cryptographically-secured timeline that can be audited, verified, and exported at any time.

Horizon is a neutral witness. It records what you declare, exactly as you declare it, without interpretation or validation.

Core Principle

Horizon is semantically neutral:

Horizon Does	Horizon Does Not
Timestamp authoritatively	Interpret your data
Chain facts cryptographically	Enforce business rules
Sign exportable proof bundles	Validate decision quality
Detect tampering	Store business logic

Your data remains yours. Horizon guarantees when it was sealed, by whom, and that it hasn't changed.
