Zero-Friction Identity: Use What You Have

The Pain Point

"Great protocol, but I don't want to generate another keypair and register another account."

Adoption dies at the "Sign Up" button.

The Solution: The "Piggyback"

Developers already have secure keys: SSH Keys (used for GitHub/GitLab).

Vouch can say: "I am `github:rampyg`."

To verify this, the protocol:

1. Asks GitHub for `rampyg`'s public SSH keys (publicly available API).

2. Checks if the Vouch signature matches one of those keys.

Result: You have an identity instantly, with zero setup.

Why It Matters

• Adoption: 100M+ developers are "pre-enrolled" in Vouch.
• UX: No new passwords to manage. Use the key you already use for git.

Key Takeaway: The best identity is the one you already have.
