This proposal presents MetaSignet, an innovative human content verification system designed to address the growing challenge of distinguishing between human-created and AI-generated content on social media platforms, with specific integration for Bluesky. By combining a user-friendly Streamlit interface with blockchain verification technology, MetaSignet provides an accessible yet powerful mechanism for creators to verify the human origin of their digital content.
MetaSignet implements a self-attestation and social vouching system that allows content creators to declare their work as human-created and build trust through community verification. The solution leverages the AT Protocol to integrate directly with Bluesky, providing a seamless verification experience that fits into creators' existing workflows.
The hybrid approach balances accessibility with security, allowing non-technical users to benefit from content verification while providing stronger blockchain-based verification for those who desire it. Beyond mere verification, MetaSignet creates a community-driven trust layer that celebrates and distinguishes human creativity in an increasingly AI-dominated content landscape.
The rapid advancement of AI content generation tools has created a crisis of authenticity on social media platforms. This problem is particularly relevant for emerging platforms like Bluesky that emphasize creator ownership and authenticity. Key challenges include:
- Content Authenticity Confusion: Increasingly difficult to distinguish between human and AI-generated content
- Creative Devaluation: Human creative work loses value when indistinguishable from AI outputs
- Attribution Issues: Original human creators struggle to claim ownership of their work
- Trust Deficit: Audiences increasingly skeptical about the authenticity of digital content
- Platform Limitations: Social platforms lack built-in mechanisms to verify human creation
The need for human content verification is growing rapidly:
- AI Content Proliferation: Text, image, and audio creation tools are becoming increasingly sophisticated
- Creator Economy Impact: Human creators are competing with AI-generated content
- Audience Value Shift: Growing audience preference for knowing when content is human-created
- Platform Trust Challenges: Social media platforms struggling with verification challenges
- Bluesky Opportunity: New platform focused on authenticity is ideal for pioneering this approach
The hybrid approach offers significant advantages:
- Accessibility: Streamlit provides a familiar, web-based interface accessible to non-technical users
- Progressive Adoption: Users can begin with simple verification and adopt blockchain as desired
- Immutable Records: Blockchain provides tamper-proof verification history
- Community Mechanisms: Smart contracts enable trustless social vouching
- Direct Integration: AT Protocol integration brings verification directly to the Bluesky ecosystem
MetaSignet offers a streamlined user experience built around three key activities:
1. Authentication Flow
- Users visit metasignet.app and click "Sign in with Bluesky"
- They enter their Bluesky credentials or app password
- MetaSignet authenticates via the AT Protocol
- No separate account creation needed - their Bluesky identity is their MetaSignet identity
2. Content Verification Flow
- User selects a post from their Bluesky feed or enters a post URL
- MetaSignet displays the post content and asks about creation method
- User selects "Entirely by me (human)" and confirms authenticity
- Optionally, user adds context about their creative process
- MetaSignet generates a content fingerprint and records the attestation
- A verification certificate is generated and displayed
3. Social Vouching Flow
- User views verification requests from their Bluesky connections
- For each request, they can view the content and choose to vouch
- User clicks "Vouch as Human" to confirm they believe the content is human-created
- After receiving multiple vouches, content verification status upgrades to "Human-verified+"
The MetaSignet interface is organized into three main tabs:
Feed Tab
- Displays the user's Bluesky posts with verification status indicators
- Unverified, Human-verified (self-attested), and Human-verified+ (community vouched) statuses
- One-click access to verify unverified content
Verify Tab
- Form to enter Bluesky post URL
- Display of post content and images
- Creation type selection (human, AI-assisted, AI-generated)
- Confirmation checkbox for human attestation
- Optional creation context input
- Verification certificate display
Community Tab
- List of verification requests from connections
- Interface to view content and vouch for human creation
- Personal vouching history
- Community impact metrics
The verification certificate serves as both proof and promotion of human-created content:
- Visual Design: Clean, professional appearance with MetaSignet branding
- Content Details: Post preview, content hash, timestamp, creator information
- Verification Level: Clear indication of self-attested vs. community vouched
- Blockchain Record: Transaction ID for blockchain-verified content
- Shareable Link: Short URL for sharing verification status (meta.sg/verify/[hash])
- Embed Code: HTML/image code for embedding verification badge on websites
MetaSignet utilizes the following technologies:
- Frontend: Streamlit (Python-based web application framework)
- Backend: Python with AT Protocol client for Bluesky integration
- Content Analysis: Image processing with PIL and imagehash for perceptual hashing
- Blockchain: Ethereum with Solidity smart contracts
- Web3 Integration: Web3.py for blockchain connectivity
- Development Tools: Remix IDE for smart contract development, Python environment
The architecture consists of four primary layers:
-
User Interface Layer:
- Streamlit web application for content registration and verification
- Bluesky authentication and content fetching
- Verification certificate display
- Community vouching interface
-
Integration Layer:
- AT Protocol client for Bluesky content access
- Content fingerprinting engine
- Verification status tracking
- Web3 connectivity (optional)
-
Verification Layer:
- Self-attestation system
- Social vouching mechanism
- Content hash registry
- Verification status rules
-
Blockchain Layer (optional):
- Smart contracts for verification logic
- Immutable verification records
- Decentralized vouching system
- Transaction management
The system implements the following key data structures:
Content Verification Record:
struct Content {
address creator; // Address of the content creator
string contentHash; // Unique hash identifying the content
string contentURI; // URI of the content (e.g., Bluesky post URL)
uint256 timestamp; // When the content was registered
CreationType creationType; // How the content was created
VerificationStatus status; // Current verification status
string creationContext; // Optional context about the creation process
uint256 vouchCount; // Number of community vouches received
string platformSource; // Platform where content originated
}Creation Types:
enum CreationType {
UNDECLARED, // Default state
HUMAN_CREATED, // Content created entirely by human
AI_ASSISTED, // Human created with AI tools
AI_GENERATED // Primarily AI-generated
}Verification Status Levels:
enum VerificationStatus {
UNVERIFIED, // Not yet verified
SELF_ATTESTED, // Creator has self-attested
COMMUNITY_VOUCHED // Has received community vouching
}The content fingerprinting system creates unique, reproducible identifiers for content:
- Text Fingerprinting: Hash generation from text content
- Image Fingerprinting: Perceptual hash generation resilient to minor modifications
- Combined Fingerprint: Unified hash combining all content elements
- Verification Lookup: Fast retrieval of verification status by content hash
The system implements several security measures:
- Bluesky Authentication: Secure handling of Bluesky credentials
- Content Ownership Verification: Ensures only the content creator can verify
- Sybil Resistance: Social graph-based vouching limits fake accounts' impact
- Immutable Records: Blockchain verification prevents history alterations
- Progressive Security: Multiple verification levels with increasing security
The MetaSignet smart contract implements:
-
Content Registration:
function registerContent( string memory contentHash, string memory contentURI, CreationType creationType, string memory platformSource, string memory creationContext ) public payable { // Validation require(msg.value >= registrationFee, "Insufficient registration fee"); require(verifiedContent[contentHash].timestamp == 0, "Content already registered"); // Create new content record Content storage newContent = verifiedContent[contentHash]; newContent.creator = msg.sender; newContent.contentHash = contentHash; newContent.contentURI = contentURI; newContent.timestamp = block.timestamp; newContent.creationType = creationType; newContent.status = VerificationStatus.SELF_ATTESTED; newContent.creationContext = creationContext; newContent.vouchCount = 0; newContent.platformSource = platformSource; // Add to creator's content list creatorContent[msg.sender].push(contentHash); // Handle registration fee if (msg.value > 0) { payable(feeCollector).transfer(msg.value); } // Emit events emit ContentRegistered(contentHash, msg.sender, contentURI, creationType); emit VerificationStatusUpdated(contentHash, VerificationStatus.SELF_ATTESTED); }
-
Social Vouching:
function vouchForContent(string memory contentHash) public contentExists(contentHash) hasNotVouched(contentHash) { require(verifiedContent[contentHash].creator != msg.sender, "Cannot vouch for your own content"); require(verifiedContent[contentHash].creationType == CreationType.HUMAN_CREATED, "Can only vouch for human-created content"); // Record the vouch contentVouches[contentHash][msg.sender] = true; verifiedContent[contentHash].vouchCount += 1; emit ContentVouched(contentHash, msg.sender); // Update verification status if threshold reached if (verifiedContent[contentHash].vouchCount >= vouchThreshold && verifiedContent[contentHash].status == VerificationStatus.SELF_ATTESTED) { verifiedContent[contentHash].status = VerificationStatus.COMMUNITY_VOUCHED; emit VerificationStatusUpdated(contentHash, VerificationStatus.COMMUNITY_VOUCHED); } }
-
Verification Status Checking:
function isHumanVerified(string memory contentHash) public view returns (bool isHuman, VerificationStatus verificationLevel) { Content storage content = verifiedContent[contentHash]; bool isHumanContent = (content.creationType == CreationType.HUMAN_CREATED); return (isHumanContent, content.status); }
The Streamlit frontend implements:
-
Bluesky Authentication:
def login_bluesky(self, username, password): """Login to Bluesky""" try: self.client.login(username, password) # Store login state st.session_state.is_logged_in = True st.session_state.bluesky_client = self.client st.session_state.bluesky_username = username return True except Exception as e: st.error(f"Login failed: {str(e)}") return False
-
Content Fetching:
def get_post_details(self, post_uri): """Fetch post details and images from a Bluesky post""" # Implementation for AT Protocol integration # Fetch post content, metadata, and images
-
