01 — Problem

The Structural Trust Gap
in Prize Campaigns

Prize campaigns still rely on opaque admin systems. Participants cannot verify whether the entrant pool changed, brands lack portable proof of fairness, and regulators receive screenshots instead of cryptographic audit trails.

Opaque Winner Selection

Winner selection often happens in private backend systems where campaign participants cannot independently verify execution integrity.

Mutable Entrant Pools

Without pre-draw snapshots and commitment proofs, it is hard to show the participant set was final before randomness was requested.

Platform-controlled Audit Logs

Audit trails are frequently vendor-owned exports that cannot be validated outside the same platform that produced them.

Weak Public Verification

Fraud and eligibility decisions are difficult to explain publicly when proof is fragmented across dashboards, spreadsheets, and support logs.

Weak public verification UX Proof console + verification flow

02 — Solution

Verifiable Draw
Lifecycle

FairDraw turns every campaign into a verifiable draw lifecycle: entrants are snapshotted, the participant set is hashed, Chainlink VRF produces randomness, and the final proof package can be downloaded and independently checked.

Implementation status map: Live — Merchant Dashboard, Embed Widget, Chainlink VRF, FD-PROOF artifacts. Beta — Campaign API facade, allowed origins, key management facade, payment modes. Roadmap — ERC-1155 standard, SDK, public explorer, compliance modules, governance layer.

03 — Architecture

Three-Layer
Gateway Model

Current stack separates campaign operations, proof commitments, and randomness execution. Roadmap components are tracked explicitly as planned layers.

Layer 3
Application Layer
Merchant Dashboard, embed widget, campaign setup surfaces, campaign API facade and media upload flow.
Layer 2
Proof / Commitment Layer
Participant snapshots, participants hash commit-reveal flow, proof endpoint, and portable FD-PROOF artifact package.
Layer 1 — Trust Root
Randomness Layer (Chainlink VRF)
Chainlink VRF v2.5 on Polygon Amoy: draw request, random word delivery, winner index derivation, and reproducible proof linkage.
Commitment Hash Locking
Participant set is snapshotted and hashed before VRF request, so the entrant pool is locked for that draw.
FD-PROOF Artifact Package
Finished draw packages include manifest.json, fd-proof.json, fd-snapshot.json, and hash_list_v1.json for portable verification.
On-chain VRF Execution
Chainlink VRF v2.5 randomness is linked to campaign state and winner derivation steps for independent re-checking.
Proof Explorer (Roadmap)
Dedicated public explorer domain is planned; current verification is available through proof endpoints and downloadable artifacts.
Integrity Groundwork
Eligibility rules, fraud signals, and pool integrity scoring provide explainable controls around campaign participation quality.

04 — Competitive Positioning

Prize Campaign Infrastructure
Positioning

FairDraw is not a gambling operator or consumer lottery app. It is an infrastructure layer for businesses that need publicly verifiable prize campaign execution.

Participant snapshot proof ~ Partial
Merchant checkout support
Portable proof artifacts ~ Partial

07 — Risk & Regulatory Framework

Controlled Risk Profile
Through Architecture

FairDraw is designed as infrastructure, not as a prize operator. Merchants configure campaigns, define eligibility, handle payment and prize fulfillment, while FairDraw provides verifiable execution and proof tooling.

Risk Factor Level Mitigation Strategy
Regulatory ambiguity MEDIUM Infrastructure positioning, merchant-controlled campaign terms, ongoing legal review.
Smart contract failure MEDIUM Testnet-first rollout, limited production scope, and external audit roadmap.
Oracle dependency LOW/MED Chainlink VRF v2.5 with fallback reconciliation and operational monitoring.
Market adoption pace MEDIUM Iframe-first integration, merchant dashboard workflow, and pilot campaign execution.
Compliance requirements MEDIUM Eligibility rules, audit artifacts, and compliance modules roadmap.

Infrastructure Positioning

FairDraw does not operate campaigns as principal. Merchants define campaign terms, eligibility, and fulfillment while FairDraw provides verifiable execution infrastructure.

Non-custodial Model

Custody and payout paths differ by payment mode. FairDraw focuses on draw integrity and proof portability, while merchant-side payment and fulfillment controls remain explicit.

Jurisdictional Strategy

Region rollout is staged by merchant profile and legal readiness, with campaign terms and eligibility rules configurable per deployment context.

Technical Audit Roadmap

Formal external smart contract audit remains on roadmap. Current operations prioritize bounded scope, controlled deployment paths, and reproducible proof artifacts.

Separation of Protocol and Prize

FairDraw emits verifiable randomness and commitment evidence. Campaign-specific eligibility, business rules, and prize delivery remain merchant-managed.

08 — Moat & Defensibility

Structural Competitive
Advantages

Defensibility in infrastructure is built through accumulation: data, integrations, compliance tooling, and switching costs that compound over time. No single moat is claimed — but the combination forms a durable competitive position.

MOAT 01

Proof Artifact Standard

Portable FD-PROOF artifacts create a consistent verification surface that merchants, auditors, and partners can adopt across campaign types.

MOAT 02

Public Verification UX

Proof console and verification flows reduce friction between campaign execution and external trust checks.

MOAT 03

Merchant Integration Workflow

Dashboard setup, embed deployment, and draw execution workflow reduce integration overhead and improve repeatability for operators.

MOAT 04

Campaign Data History

Accumulating campaign and draw history improves operational quality, replayability, and proof consistency over time.

MOAT 05

Compliance Workflow Accumulation

Eligibility, fraud signals, and audit workflow improvements compound with each deployment and reduce marginal compliance effort.

MOAT 06

Embedded Switching Cost

Operators that run repeated embedded campaigns build process and data dependencies that increase switching cost over time.
