STProof Protocol Whitepaper

Version: v6.5 | 2026

Fact Layer of Digital Civilization

Not Proof of Asset. Only Proof of Event.

Abstract

STProof is a decentralized event-based on-chain proof protocol. It certifies objectively occurred events with multi-source evidence, trusted timestamps, IPFS storage, and validator attestations.

Version 6.5 rebuilds the economic model to be sustainable, compliant, and realistic, removing unfeasible citation fees and introducing a collectible stamp-style economy, limited-edition event NFTs, dynamic evidence, and a curation system (Storyline).

The protocol now supports Event Collection Gameplay, similar to stamp or postcard collecting, making the ecosystem self-sustaining and user-driven.

1. Introduction

The digital age suffers from trust collapse: forgery, deepfake, and manipulation make facts untrustworthy.

Blockchain provides immutability, but most solutions only certify files, not real events.

STProof changes this:

  • It certifies what happened
  • When it happened
  • Who participated
  • What evidence supports it
  • Without binding physical ownership or financial risks

STProof v6.5 is designed for real adoption, real users, and real sustainability.

2. Core Concept

STProof focuses only on event certification.

It proves:

  • Occurrence of an event
  • Authenticity of evidence
  • Validity via validator attestation
  • Historical traceability

It does NOT certify:

  • Ownership of physical assets
  • Value of assets
  • Legal title or property rights
  • Investment or financial returns

3. Event NFT Model (ERC-721)

Each event is minted as an Event NFT.

The NFT represents:

  • The event itself
  • Evidence chain
  • Verification status
  • Edition number (limited editions)
  • Collection eligibility

It does NOT represent:

  • Physical objects
  • Financial assets
  • RWAs
  • Investment contracts

4. Protocol Architecture

  1. Event Layer – Event templates and standards
  2. Evidence Layer – IPFS + trusted timestamp + version history
  3. Validation Layer – Permissionless validator + multi-sign attestation
  4. NFT Layer – ERC-721 limited-edition assets
  5. Economic Layer – Sustainable collectible economy
  6. Storyline Layer – Curation, collection, and narratives
  7. Security Layer – Reentrancy guard, access control, audit-ready

5. Economic Model (v6.5 – Sustainable & Realistic)

STProof v6.5 removes citation fees entirely, as they are not operationally feasible.

The new model is collectible-driven, service-based, and compliant.

5.1 Revenue Sources

  1. Limited-Edition Minting Fees Official series, stamp-style collectibles, thematic sets.

  2. Verified Event Services Validation by trusted attestors.

  3. Secondary Market Royalties (5%) EIP-2981 compliant.

  4. Institutional & Enterprise API Services For media, legal, academic, and museum clients.

5.2 Revenue Distribution

  • 70% Event Creator
  • 28% Treasury
  • 2% Protocol Development & Maintenance

5.3 Advantages

  • No unfeasible citation fees
  • Compliant collectible model
  • Stable, real-demand revenue
  • User-driven growth via collection gameplay
  • Zero financial or security risks

6. Key Features in v6.5

6.1 Limited-Edition Event NFTs

  • Fixed editions (e.g., 1/100, 1/500)
  • CID anti-duplication
  • Stamp/postcard-style collection support
  • Perfect for series and themes

6.2 Dynamic Evidence System

  • Append new evidence anytime
  • Full on-chain version history
  • IPFS-based immutable proof
  • Audit and legal-friendly

6.3 Validator Attestation System

  • Permissionless validator registration
  • Multi-sign validation (≥ 2 validators = verified)
  • On-chain attestation with comment CIDs

6.4 Storyline Curation Module

  • Create public/private collections
  • Group events into series or stories
  • Upvote and community governance
  • Foundation of the Event Collection Game

6.5 Security Hardening

  • Reentrancy protection
  • Zero-address validation
  • Safe transfers
  • Manual revenue withdrawal (compliance-focused)

6.6 Standard Compatibility

  • ERC-721
  • EIP-2981 (Royalty)
  • ERC-165 (Interface Detection)

7. Event Collection Game (Stamp / Postcard Style)

Each event = one collectible stamp Each series = a complete set Users:

  • Mint
  • Collect
  • Complete sets
  • Showcase in Storyline
  • Trade safely

This creates natural, sustainable, and fun user activity.

8. Use Cases

  • Fact-checking & journalism
  • Art creation certification
  • Academic publication proof
  • Legal evidence archiving
  • Cross-border behavior verification
  • Historical event curation
  • Digital stamp / postcard collection
  • Institutional archiving

9. Compliance & Risk Disclosure

STProof is a fact-certification and collectible system.

It is NOT:

  • A security
  • A financial product
  • An investment vehicle
  • An RWA platform
  • A physical ownership certificate

10. Roadmap

  • v6.5: Economic rebuild, limited editions, collection game, security hardening
  • v7.x: DAO governance
  • v8.x: Cross-chain event proof
  • v9.x: AI-assisted validation
  • Vision: Become the Fact Layer of Web3

11. Conclusion

STProof v6.5 establishes a fully practical, secure, and sustainable infrastructure for event certification.

By adopting a collectible-driven economic model, it turns factual proof into a user-friendly, scalable, and compliant ecosystem.

What happens, exists. What’s proven, trusted.
