The Synchrony Layer: Shared Context Infrastructure for AI-Generated Software

Abstract

This paper introduces the Synchrony Layer, a shared context and coordination standard for AI-generated software. As AI makes it easy for anyone to generate apps, workflows, agents, and automations, software ecosystems risk becoming fragmented across schemas, permissions, APIs, dependencies, provenance, runtime behavior, and approval rules. The Synchrony Layer addresses this by turning generated code into structured Generated Software Objects with formal specs, schemas, permissions, validation rules, compatibility semantics, provenance records, update policies, and execution receipts. The paper presents STACY Sync as a reference implementation for web, mobile, backend, workflow, agentic, off-chain, and on-chain software systems. It also explains how blockchain and data-availability layers such as Avail, Celestia, and EigenDA/EigenLayer can support public shared context for marketplaces, agent ecosystems, Web3 applications, attestations, provenance, and auditable execution records. Core thesis:AI makes software abundant. Synchrony makes abundance usable.
