Copyright Verification System
A digital copyright protection system based on cryptographic hash chains and multi-layer time anchoring, providing tamper-proof proof of temporal existence for every chapter — with judicial evidentiary force.
I. Core Principle: The Self-Verifying Hash Chain
After each chapter is written, the system automatically computes its cryptographic hash fingerprint。 This fingerprint is not arbitrarily generated — it strictly follows a chain structure: each chapter's hash is derived from Chapter Content + the previous chapter's hash + a precise timestamp + an author identity marker — these four elements, processed through SHA-256 -256 algorithm. This means the hash value cryptographically binds "who — when — wrote what" into an inseparable unity.
Chapter 1
(Content₁+0+Time₁+Author)
Hash₁
(Content₂+Hash₁+Time₂+Author)
Hash₂
(Content₃+Hash₂+Time₃+Author)
Hash₃
Chain End
Author Identity Binding
Each chapter's hash embeds the author's registered email( (verified), cryptographically binding the creator's identity to the content. Email is a globally unique external identity marker—— — Chinese email providers (QQ/163 , 163, etc.) all require real-name registration. Account real-name information can be retrieved from email providers, forming a complete evidentiary chain from "Real-Name Identity → Email → Hash Chain → Creative Content".
Even if two authors wrote identical content (extremely unlikely), the hashes would be completely different due to different email addresses. AuthorChanging the bound email does not affect verification of historical chapters — each chapter independently records the email address at the time of hash creation, permanently preserving the historical evidence.
Mathematical Guarantee Against Tampering
SHA-256 is an internationally recognized cryptographic hash algorithm with preimage resistance and collision resistance—— — meaning it's impossible to reverse-engineer the original text from its hash, or find two different inputs that produce the same hash. This guarantees:
- One-way irreversibility: The chapter content cannot be reverse-engineered from its hash value.
- Uniqueness: Any change to content or author — even a single character — produces a completely different hash value.
- Chain locking: Modifying any single chapter breaks the hashes of that chapter and all subsequent chapters. Since every chapter's timestamp and author identity are fixed, the entire chain cannot be rebuilt without detection.
II. Merkle Tree: Work-Level Fingerprint Aggregation
All chapter hashes of a work are organized into a Merkle tree,. Through pairwise hashing layer by layer, they produce a unique 64-character hex value — the Work Merkle Root。 This Root is the single cryptographic fingerprint ,of the entire work. Anchoring this single value provides temporal proof for all chapters of the work.
Similarly, every day, the Merkle Roots of all updated works on the platform are built into a new Merkle tree, producing the daily Platform MetaRoot。 . A single anchor covers the copyright status of all works across the entire platform for that day, enabling efficient large-scale copyright protection.
III. The Four-Layer Evidence System
Layer 1: Chain-Based Evidence
Chain hashes are generated in real time after each chapter, forming a mathematically tamper-proof fingerprint chain. This is the cryptographic foundation ,of the entire system and can be independently verified.
Layer 2: Email Timestamp
A daily verification digest is automatically sent to the author's email, containing the hash fingerprints of new chapters and the Merkle Root. The sending records retained by email providers constitute independent third-party time evidence。
Layer 3: Judicial Time Anchoring
Submit the Platform MetaRoot to an authorized timestamp authority recognized by the National Time Service Center, obtaining a trusted timestamp certificate with judicial evidentiary force (compliant with the Electronic Signature Law).
This layer is a paid feature,, not yet implemented. Notification will be provided when it goes live.
Layer 4: Blockchain Notarization
Write the MetaRoot to a blockchain distributed ledger, witnessed and permanently stored by tens of thousands of nodes worldwide. Blockchain records are undeletable, unforgeable, and permanently verifiable( (explicitly recognized by the Supreme People's Court judicial interpretation).
This layer is a paid feature,, not yet implemented. Notification will be provided when it goes live.
IV. Defense in Depth: Why This System Cannot Be Breached
Server-Side Tampering?
Even if the platform server is fully compromised, an attacker cannot tamper with historical data without being detected:
- Daily emails already sent to the author's inbox and the email provider's servers contain the Merkle Root at that time — this is external evidence independent of this platform
- Records on timestamp services and blockchains are one-way and irreversible — they cannot be revoked or modified
- Any tampering will cause the hash chain to break, and the break point can be precisely located.
Preemptive Forgery?
To preemptively generate chapters in bulk and forge a timeline, an attacker would need to:
- Predict all future content — impossible in a real creative scenario.
- Forge the email provider's send time — email providers are independent third parties outside the attack surface.
- Forge blockchain or timestamp records — would require breaking cryptographic guarantees, computationally infeasible.
Collusion?
Even if the platform colludes with a participant, multiple layers of the four-layer evidence system remain independent of the platform: Email providers, timestamp authorities, and blockchain networks are all independent third parties, that do not rely on platform trust. Evidence preserved in any single layer is sufficient to prove rights ownership.
V. Independent Verification
Online Verification
On the novel reading page, click the "Verify Chain" button. The system will recalculate hashes chapter by chapter, compare them to stored values, and report chain integrity in real time.
Evidence Package Download & Offline Verification: On the novel page, click "Download Evidence" to download a JSON evidence package, then visit the /verify verification page. Import the evidence package and paste the chapter text to independently recompute the hash chain in your browser using the Web Crypto API — all computations run locally, independent of our servers. Third parties (including forensic institutions) can verify independently.。 All computations are performed locally, independent of our platform servers. Third parties (including forensic institutions) can verify independently.
Offline Independent Verification
All hash calculations are based on the open international standard SHA-256 algorithm. ,No proprietary technology is involved. Any third party (including forensic institutions and copyright arbitration bodies) can:
- Obtain the evidence package (JSON format, including the hash list, timestamps, and all data) via the "Download Evidence" button on the novel page.
- Use any programming language or standard tool to compute hashes chapter by chapter following the public formula.
- Compare the computed results to determine whether the chain is intact.
Forensic Pathway
In a copyright dispute, the following evidence can be sequentially obtained to form a closed loop:
- Server Data: Complete hash chain and Merkle Tree records.
- Email Records: Proof of sending time and content issued by the email provider.
- Timestamp Certificate: Trusted timestamp certification issued by an authorized timestamp authority.
- Blockchain Records: Publicly queryable blockchain transactions and block heights.
These four types of evidence independently prove the same fact from different dimensions — that specific content definitely existed at a specific point in time, — forming a complete evidentiary chain loop.
VI. Frequently Asked Questions
What Does Verification Prove?
It proves temporal existence—— — that at a precise point in time (accurate to the second), specific creative content already existed. In copyright disputes, this is core evidence: if you can prove your content existed before the other party's publication time, it constitutes a powerful prior-rights proof.
What Happens to the Verification Chain When a Chapter Is Modified?
When a chapter is modified, the system preserves the complete version history ((including the original text before modification, modified content, and precise modification time), and automatically recalculates the hash chain for that chapter and all subsequent chapters, to ensure the integrity of the entire chain.
The original text and hash before modification are preserved in version history and can be reviewed or restored at any time. If a daily verification email was already sent before the modification, that email (containing the old hash and Merkle Root) constitutes third-party time evidence independent of this platform, — the email provider's sending records cannot be deleted. This means your creative evolution is fully traceable。
What Do I Need to Do?
Nothing at all.The verification system runs fully automatically: hashes are generated after each chapter, verification emails are sent daily, and the platform periodically performs time anchoring. Creators simply write as usual — copyright protection happens silently in the background.
How Are Long-Running Serials Protected?
Long-running serials are the scenario this system handles best. New chapters produced daily are automatically incorporated into the hash chain, with time evidence solidified via email. Even if a work serializes over several years, every chapter has independent, day-by-day accumulated time proof, forming a complete evidence chain that grows in sync with the creative process.
