STProof Protocol Whitepaper

Version: v6.3 | April 2026

Fact Layer of Digital Civilization

Core Slogan Not Proof of Asset. Only Proof of Event. What happens, exists. What’s proven, trusted.

Physical belongs to the physical world. Events belong to the blockchain.

0. Preface

STProof is a universal on-chain protocol dedicated to proving objectively occurred historical events. It does not tokenize physical assets, does not map real-world assets (RWAs), and does not bind ownership of any physical item.

The protocol’s first certified event is STProof itself: a self-referential experiment that forms the trust root of the entire system.

This version, v6.3, upgrades the smart contract architecture for security, robustness, gas efficiency, and sustainable economics.

1. Abstract

STProof (Spatial-Temporal Proof) is a decentralized event-based verification and value-capture protocol built on blockchain. It records, verifies, and certifies real-world events using multi-source evidence cross-verification, trusted timestamps, decentralized storage (IPFS), and on-chain anchoring.

The protocol only certifies events, not assets. It supports three categories:

  • Tangible Events (with physical carriers)
  • Intangible Events (digital-native, no physical object)
  • Hybrid Events (online + offline)

STProof v6.3 introduces:

  • Manual revenue withdrawal
  • Validator attestation system
  • Enhanced security framework
  • Fixed-edition NFT support
  • Gas optimization and batch operations
  • Modular, extensible architecture

The protocol’s value capture mechanism is driven by citation royalties, resale royalties, and paid evidence access. Value comes from public trust and usage, not speculation.

STProof provides a credible, compliant, and censorship-resistant fact layer for Web3 and digital civilization.

2. Introduction

2.1 The Crisis of Fact

In the era of AI and deepfakes, authenticity is collapsing. Traditional fact-recording systems rely on centralized authorities, which are inefficient, costly, and hard to verify cross-border.

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

2.2 The Missing Fact Layer

The world needs a system that:

  • Proves events, not assets
  • Works without exposing private data
  • Is decentralized and immutable
  • Is compliant and non-financial
  • Scales to all human behaviors

2.3 The STProof Solution

STProof creates a trust layer for events. It answers:

  • When did it happen?
  • Where did it happen?
  • Who was involved?
  • What exactly occurred?
  • What evidence proves it?

3. STProof Protocol

3.1 Definition

STProof is a universal on-chain event certification protocol. It turns real-world facts into verifiable, permanent, and composable digital records.

3.2 Core Philosophy

  • Physical belongs to the physical world.
  • Events belong to the blockchain.
  • NFTs lock events, not assets.
  • Facts should be accessible to all.

3.3 Three Event Categories

  1. Tangible Events: art creation, physical mailing, excavation
  2. Intangible Events: publication, voting, statement, protocol deployment
  3. Hybrid Events: live news, performances, legal deposits

3.4 Five Core Elements

Every event contains:

  • Time
  • Location / Spatial coordinate
  • Actor / Subject
  • Behavior / Fact
  • Evidence package

3.5 Zero-Knowledge Ideology Proof

STProof uses a practical verification system:

  • Prove truth without exposing raw data
  • Prove validity without revealing IP or privacy
  • Verify via cross-source consistency

This is the foundation of compliance and scalability.

4. Event NFT Model

4.1 Event-Based NFT (ERC-721)

The NFT represents:

  • Occurrence of an event
  • Evidence structure
  • Validation status
  • Citation history
  • Attribution

It does NOT represent:

  • Physical objects
  • Asset value
  • Ownership rights
  • Financial claims

4.2 Physical-Digital Separation

Physical objects remain in the physical world. NFTs only record historical events. No RWA. No ownership mapping. No collateral.

This eliminates regulatory risk.

5. Protocol Architecture

5.1 Template Layer

Defines validation rules for different event types.

5.2 Evidence Layer

IPFS + trusted timestamp + multi-source cross-proof.

5.3 Validation Layer

Validators attest to event authenticity.

5.4 NFT Layer

Dynamic ERC-721 with updatable metadata.

5.5 Economic Layer

Royalties, citations, paid access.

5.6 Security Layer

Access control, reentrancy guard, emergency pause.

6. Smart Contract v6.3

6.1 Overview

STProof v6.3 is a secure, production-ready smart contract.

6.2 Core Upgrades

  • Manual revenue withdrawal
  • Validator attestations
  • Fixed-edition NFTs
  • Reentrancy protection
  • Role-based access control
  • Batch operations
  • Gas optimization
  • Emergency pause per module

6.3 Key Functions

  • mint / mintWithIncentive
  • verify / verifyBatch
  • cite
  • addAttestation
  • setFixedEdition
  • grantAccess
  • withdrawCreatorRevenue
  • withdrawTreasuryRevenue
  • withdrawProtocolCreatorRevenue

6.4 Security

  • ReentrancyGuard
  • 2-step ownership transfer
  • Full parameter validation
  • Comprehensive event logging
  • Treasury multi-sig support

7. Economic Model

7.1 Value Comes From Usage

An event’s value = citation count + trust + usage.

7.2 Three Revenue Streams

  1. Resale Royalty (5%, EIP-2981)
  2. On-Chain Citation Fee
  3. Paid Evidence Access

7.3 Revenue Distribution

  • Creator: 70%
  • Treasury: 28%
  • Protocol Creator: 2%

7.4 Manual Withdrawal (v6.3 Feature)

All revenues accumulate in the contract. Users withdraw manually. Safer, more transparent, more robust.

7.5 Protocol Creator Equity

2% permanent on-chain equity for maintenance, security, and ecosystem development.

8. Roles

8.1 Event Creator

Initiates, collects evidence, mints NFT.

8.2 Validator

Verifies events and submits attestations.

8.3 User

Cites events, accesses evidence.

8.4 Treasury

Supports public goods and community development.

8.5 Protocol Creator

Maintains contracts and security.

9. Evidence System

9.1 Multi-Source Cross-Proof

At least two independent sources.

9.2 Trusted Timestamp

Proves existence at a certain time.

9.3 Decentralized Storage

IPFS / Arweave for immutability.

9.4分层披露

Public package & full package.

10. Use Cases

  • Journalism Fact-Checking
  • Art Creation Certification
  • Academic Publication
  • Legal Evidence Deposit
  • Cross-Border Behavior Proof
  • Protocol & Contract Deployment
  • DAO Voting & Governance Records
  • Physical & Hybrid Events

11. Genesis Case: Self-Referential Experiment

The first event certified by STProof is STProof v6.3 itself.

  • Event: Protocol Deployment
  • Type: Intangible / Digital-Native
  • Evidence: Contract hash, timestamp, GitHub CID, IPFS
  • Purpose: Form a self-referential trust root

This is the meta-event of digital civilization.

12. Compliance & Risk Disclosure

STProof is:

  • NOT a security
  • NOT a financial product
  • NOT an investment vehicle
  • NOT an RWA platform
  • NOT ownership certification

It is a fact-recording infrastructure.

13. Roadmap

  • v6.3: Secure Economics + Attestations + Manual Withdrawal
  • v7.x: DAO Governance
  • v8.x: Cross-Chain Event Proof
  • v9.x: AI-Assisted Validation
  • Vision: Fact Layer of Web3

14. Conclusion

STProof v6.3 establishes a decentralized, compliant, and sustainable fact layer.

By focusing only on events, it creates a new trust infrastructure for digital civilization.

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