Portable Trust Scores: How TrustDPV Verifies Online Identity Without a Central Authority

Every online platform reinvents trust from scratch. eBay has feedback scores. Upwork has job success ratings. Reddit has karma. But none of them talk to each other.

If you're a great seller on eBay with 500 positive reviews and you join Facebook Marketplace, you're a nobody. Start from zero. Hope someone trusts you enough to give you a chance.

That's the problem TrustDPV solves.

The concept

TrustDPV gives you a portable trust profile. You connect accounts you already have - GitHub, Google, Discord, LinkedIn, WordPress, GitLab - and we verify that you actually own them. Other verified users can endorse you. The result is a Trust Score from 0 to 1000 that follows you wherever you go.

One link. One badge. One score.

How the Trust Score works

The scoring is fully transparent. No black box:

• Name (25 pts) - Providing your real name
• Bio (15 pts) - Writing a profile description
• Verified platforms (100 pts each, up to 600) - Connecting and verifying real accounts
• Endorsements (up to 200 pts) - Other verified users vouching for you
• Account age (up to 60 pts) - How long you've been on TrustDPV

The maximum possible score today is 1000. If we add more platforms, the ceiling grows.

The verification process

When you connect a platform, we use OAuth to verify you own that account. No password sharing. We never see your credentials. For LinkedIn, we only display "LinkedIn verified" - no personal details exposed. Privacy by design.

For developers

TrustDPV has a free API (60 requests/min) with:

• Verification endpoint - check if a user is verified and their trust score
• Profile endpoint - full public profile data
• Batch verification - verify up to 50 users at once
• Embeddable widget - drop a trust badge on any site with one line of JS
• Webhooks - real-time notifications for trust score changes
• SDKs - JavaScript (npm) and PHP (Composer)

const TrustDPV = require('trustdpv');
const tdpv = new TrustDPV({ apiKey: 'your_key_here' });

const result = await tdpv.verify('username');
// { valid: true, trust_score: 660, verified: true }

The static SVG badge works in emails, forums, and marketplace listings - anywhere that supports images.

Trust Score

Why this matters

Trust shouldn't be owned by platforms. It should be portable. Your reputation should follow you, not the company you're selling on.
