Data Validation for the Geeks
Here, we’ll walk you through how SecondBrainDAO validates the data you share—your browser history, location history, and bookmarks. These validation checks ensure your contributions are unique, authentic, and high-quality, making your Second Brain smarter and more reliable. Let’s break it down step by step, so you can see exactly how it works and how to contribute your data.
Ownership in SecondBrainDAO
In SecondBrainDAO, ownership of submitted data is a key principle that ensures the platform operates with integrity and fairness. When users submit files, SecondBrainDAO takes careful steps to verify that the data belongs to the person submitting it. This process prevents unauthorized uploads and ensures that only rightful owners can claim rewards for their contributions.
How Ownership is Verified
SecondBrainDAO uses a secure and reliable system to confirm ownership of every file submitted. Here’s how it works:
Cryptographic Signature: Each file submission includes a cryptographic signature created with the user’s private key. This signature is unique to both the data and the submitter, acting as a tamper-proof seal. By verifying this signature against the submitted file, SecondBrainDAO confirms that the data belongs to the submitting user.
Wallet Address Linking: When a user submits data through the SecondBrainDAO platform, the submission is tied to their wallet address. This wallet address is a blockchain-based identifier that uniquely links the file to its owner. It creates a clear and traceable record of who submitted the data.
The ownership verification process is designed to protect users and maintain trust in the platform. Here’s why it’s important:
Prevention of Fraud: The use of cryptographic signatures ensures that no one can submit data they don’t own. This protects against impersonation, theft, or fraudulent claims.
Transparency: By linking submissions to wallet addresses, SecondBrainDAO creates an immutable and transparent record of ownership. Anyone can trust that the process is open and verifiable.
Fairness: Verifying ownership guarantees that rewards go only to legitimate contributors. This keeps the system fair for everyone involved.
Browser History Validation
Your browser history is a map of your online journey, and we analyze it to ensure it’s both valuable and accurate.
Browser History Validation Metrics
Uniqueness Score
How it’s calculated: Number of unique entries ÷ Total number of entries.
Why it matters: A higher score reflects diverse browsing habits, giving your Second Brain a wider lens on your interests.
Authenticity Score
How it’s calculated: We check if time spent per page is realistic (between 2 seconds and 2 hours). Entries outside this range—like quick accidental clicks or tabs left open for days—get a penalty.
Why it matters: This weeds out noise, ensuring your data mirrors your actual online behavior.
Quality Score
How it’s calculated: We confirm three things:
All required fields (e.g., URL, timestamp) are included.
URLs are valid (starting with http:// or https://).
Time spent falls within the valid range (2 seconds to 2 hours).
Why it matters: This guarantees your data is complete, reliable, and ready to fuel your Second Brain.
How to Share Your Browser History
Microsoft Edge: Upload your default browser history file.
Brave or Chrome: Install the “Chrome History Analysis to CSV” extension, export your history as a CSV file, and submit it.
Location History Validation
Your location history ties your digital life to the real world, tracking where you’ve been—whether globetrotting or just around the block.
Location History Validation Metrics
Uniqueness Score
How it’s calculated: Ratio of unique location entries to total entries.
Why it matters: More unique spots paint a vivid, varied picture of your movements for your Second Brain.
Authenticity Score
How it’s calculated: If your data passes the Quality Score checks (i.e., it’s correctly structured), you score a 1.0. If not, it’s lower.
Why it matters: This ensures your location data is formatted properly and usable.
Quality Score
How it’s calculated: We run these checks for realism:
Suspicious Speed: Does distance traveled align with reported speed? (No teleporting allowed!)
Time Order: Is the start time before the end time for each activity?
Probabilities: Are probability values between 0 and 1?
Hierarchy Levels: Are hierarchy values (if included) between 0 and 1?
Waypoints: Are latitude (-90 to 90) and longitude (-180 to 180) values valid?
Regular Intervals: Are time gaps between activities consistent?
Why it matters: These ensure your location data is logical and reflects real-world travel.
How to Share Your Location History
Upload your location history in JSON format. Our system will run the checks and confirm its quality.
Bookmark Validation
Your bookmarks are a curated list of your favorite online destinations. Here’s how we assess them:
Bookmark Validation Validation Metrics
Uniqueness Score
How it’s calculated: Ratio of unique bookmarks to total bookmarks.
Why it matters: A higher score reveals a broad range of interests, helping your Second Brain get to know you better.
Authenticity Score
How it’s calculated: No bookmarks = 0. At least one bookmark = 1.
Why it matters: This basic check confirms you’ve submitted something to evaluate.
Quality Score
How it’s calculated: The more bookmarks you provide, the higher your score.
Why it matters: A bigger set gives your Second Brain more to learn from and work with.
How to Share Your Bookmarks
Export your bookmarks as an HTML file (supported by most browsers), upload it, and our system will process the data and calculate your scores.
Why This Matters
These validation steps aren’t just formalities—they’re the backbone of a powerful Second Brain. By sharing your browser history, location history, and bookmarks, you’re building a richer digital self and supporting the SecondBrainDAO community. Oh, and did we mention? You’ll earn rewards for contributing!
