The Brief

What you'll do, and what you'll demonstrate.

Design a cross-chain bridge protocol with an explicit threat model covering at least 12 named attacks, plus a working lock-and-mint prototype.

This is not a design exercise. It is the work a product designer does between a brief and a shipped interface. That distinction matters to every hiring manager who has seen candidates redesign Spotify's homepage and none who have worked under real product constraints.

When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."

Earning criteria — what you'll demonstrate

  • Design a non-trivial cross-chain protocol from first principles
  • Reason about validator economics + slashing as a security primitive
  • Build an explicit threat model with named attacks + mitigations
  • Communicate a security-critical design to an audit team
