Distributed Validation Infrastructure

When research can't be reproduced, knowledge becomes unreliable. ValiChord coordinates independent validators to verify research findings through an eight-layer infrastructure designed to resist institutional capture. Results can't be altered, censored, or removed.

The study design
How we measure validation workload — 20–25 studies, 3 validators each, structured time tracking. The empirical foundation for everything that follows.
Vision & Architecture
What ValiChord is and how it works
The complete system design — eight layers, from data integrity to journal integration. Plain language, for anyone who wants to understand the project.
Governance Framework
How the system resists capture
Anti-corruption mechanics, transparent decision-making, term limits, and why ValiChord is designed to be governed, not owned.
Open Design Questions
What we don’t know yet
Thirteen unresolved design problems — with precedents, likely approaches, and which phase resolves each one. Honest acknowledgment over silence.
About

Most published computational research has never been independently verified. Not because verification is impossible — but because no infrastructure exists to coordinate it, compensate the skilled researchers who do it, or preserve what they find.


ValiChord is a proposed distributed infrastructure for structured, independent verification of computational research. Multiple validators independently reproduce published analyses. Their results — including disagreement — are preserved in full, permanently, in tamper-evident form. Nobody can soften, suppress, or average away an inconvenient finding.


Validation becomes visible work. Validators are compensated for their expertise, credited by name in permanent records, and recognized through formal attestations that appear on their professional profiles. The system resists capture — funders cannot suppress inconvenient findings, institutions cannot game results, and validators cannot be pressured to soften disagreement. This creates a research culture where verification is valued labour, not invisible service.


Built on Holochain — a distributed architecture that is architecturally distinct from blockchain. Where blockchain requires a single global ledger with energy-intensive consensus, Holochain keeps data local to each participant and distributes only cryptographic proofs, enabling GDPR compliance without the infrastructure costs that made blockchain approaches unviable for research


Currently in pre-funding development. Architecture validated by the Holochain Foundation. Seeking a Principal Investigator and institutional home for Phase 0 — the empirical study that measures what validation actually costs, funded through UKRI’s Metascience programme.

“A chord is multiple notes sounding together.
Agreement is harmony. Disagreement is dissonance.
Both carry information.”
