A high-security credential format enabling selective disclosure and unlinkability via salted cryptographic hashes.

SD-JWT VC (Selective Disclosure JSON Web Token Verifiable Credentials) solves the oversharing problem in digital identity. By applying salted hashes to individual claims within a standard JWT, it allows users to reveal only specific data points: showing a '18+' flag without exposing a full birthdate. This IETF-backed specification ensures hardware-backed security and prevents tracking across different verifiers through unique per-presentation salts. It is the core engine for the EU Digital Identity Wallet (EUDI) and ISO 18013-7 mobile driver's licenses.

### [Agnic.AI: Payable Agents & a New Monetization Layer for AI Builders](https://toronto.aitinkerers.org/talks/rsvp_ZgqPADQ3wBs)

Agnic.AI is a system for turning AI agents into self-sovereign economic actors that can earn, spend, and prove identity on-chain. In this demo, I’ll show how I built agents that can autonomously complete tasks with programmable payment rails, and attach verifiable identity and skill signals (inspired by OpenClaw-style "Pay + ID" skills). The project explores how agents move from being tools to participants in an open marketplace.
