From architecture to the world's privacy-first data rail for loyalty and payments

Where ValiDeck stands today

ValiDeck’s roadmap sets out the activities the company will undertake to advance PCX, a proposed privacy-first interoperability layer that lets transaction records work across merchants without exposing customer identity. The work will run in two phases, from completed architecture to demonstrated implementation. Phase I will establish and validate the data rail. Phase II will use the resulting trusted data asset to enable privacy-preserving services and commercial applications.

The architecture and Phase I design are complete, and the patent foundation is established across multiple jurisdictions. The next milestone is the funded build and independent validation of the first reference prototype.

Establish the Data Rail

Phase I will establish and validate a privacy-first data rail by capturing and synthesizing pseudonymous customer transaction records (CTRs) and review signals without exposing identity. Work will begin in a controlled environment and expand through PoS and merchant-side integration.

Activities

  • Capture card transactions pseudonymously in customer-controlled accounts.
  • Connect implicit and explicit experience signals across products, merchants and services.
  • Protect customer identity by enabling loyalty participation through tokenized identifiers.
  • Prove the complete end-to-end flow using reference applications, PoS integration and APIs.

Outcomes

  • Working prototype: A complete end-to-end Phase I reference prototype.
  • Initial data asset: The first controlled accumulation of CTRs and review signals.
  • Architectural validation: Evidence that capture, pseudonymous linkage and customer control operate together as intended.
  • Stage-gate proof: Proof of the rail — not yet a mature commercial platform.

Why Phase I comes first

Phase I will establish the trusted data asset on which the rest of the strategy depends. By demonstrating transaction capture, pseudonymous linkage and customer control together, it will create the reliable dataset needed for later ranking, analysis and monetization.

Monetize and Expand

Phase II will begin only after Phase I has demonstrated reliable capture and sufficient signal density. It will use aggregated CTR and review data to deliver services that create commercial value without exposing raw customer records.

Activities

  • Deliver privacy-preserving search results for products, businesses and services using cohort-level ranking, so verified behavior — not advertising — determines relevance.
  • Enable capability-based discovery that ranks products, businesses and services by verified operational capability rather than marketing claims or bids.
  • Power decision support and marketplace insights using aggregated cross-merchant spending behavior.
  • Reward customers through consent-based, cohort-level promotions without identifying named individuals.
  • Provide business insight APIs and selected professional services for markets that depend on verified, high-trust signals.

Outcomes

  • Search and discovery: Privacy-preserving results and capability-based discovery informed by verified behavior.
  • Decision support: Marketplace insights and consent-based, cohort-level promotions derived from aggregated data.
  • Commercial interfaces: Business insight APIs and selected professional services supported by a trusted, sufficiently dense CTR and review dataset.
  • Commercial proof: Evidence that the rail can create value without exposing raw customer records.

Advancing PCX in parallel

Alongside product development, ValiDeck will advance PCX toward formal standardization within the European regulatory framework, beginning with PCX-CTR. The Phase I prototype will serve as the first reference implementation; ValiDeck will not serve as the governing body.
