IIP-051: AFT Verification Client

IIP-051 Roadmap Record

IIP-051: AFT Verification Client is an IOI roadmap implementation record for the IOI Runtime surface. It is marked Gated in Q4 2026 and belongs to the Runtime Substrate track. The canonical scope is: Light-weight verification client within the runtime daemon for validating AFT consensus headers and state-channel proofs.

Surface Context

This IIP should be read as part of the IOI Runtime roadmap, not as a replacement for source papers or product pages. The parent surface gives the broader context for why this milestone exists, what it depends on, and which IOI surfaces it supports. IIP-051 depends on the protocol surface before it can fully mature. It unblocks later roadmap surfaces: authority-gateway, hypervisor.

Evidence And Verification

The record is designed to make roadmap evidence crawlable and separable from research claims. This item also names item-level dependencies: IIP-026. Evidence links below point to the paper, release, repository, developer documentation, or product page that supports this milestone.

Canonical Relationship

This page is the canonical implementation record for IIP-051, while the parent roadmap surface and linked research pages remain the canonical sources for broader product and protocol context. Internal links point here when the milestone status, phase, dependencies, or evidence trail for AFT Verification Client matters.

Roadmap Role

IIP-051 exists to clarify roadmap status, implementation scope, and evidence relationships. Technical concepts flow through this page to canonical research pages, while product or runtime context flows to the relevant surface page. This preserves a complete implementation trail without making roadmap records compete with deeper IOI papers.
