Building a Web of Trust with URLs

Building decentralized trust using DNS and URLs. How did:web enables verifiable identity without blockchain.

The Pain Point

"I trust Alice." Alice trusts Bob. Should I trust Bob? Maybe a little bit. Real trust is a network, not a list. Current systems force you to manually check everyone.

The Solution: Follow the Links

Vouch Credentials contain URLs to other credentials.

  • "I am a Senior Dev" (Signed by Google) -> URL to Google's issuer key.
  • "I wrote this code" (Signed by Senior Dev) -> URL to "Senior Dev" credential.

The verifier software automatically follows these links (spidering) to build a Trust Graph. It calculates a "Trust Score" based on who vouched for whom.

Why It Matters

  • Scale: You don't need to know everyone personally. You just need a path of trust to them.
  • Nuance: Trust isn't binary (Yes/No). It's a gradient based on the strength of the chain.
Key Takeaway: Trust is a graph. Your software should be able to traverse it.
