Founder, Vértice Criativo · verifiable AI infrastructure — and 15+ years an audio engineer

Building systems whose output you can re-derive yourself instead of taking on trust · Ethereum standards contributor · Lisbon

I run Vértice Criativo (Lisbon), building infrastructure for AI systems whose actions can be independently re-derived — not attested by the vendor, re-computed by you.

Every agent action we run is checkable from public data by someone with no relationship to us: input hash, sanitisation, output hash, on-chain anchor, signature recovery. Try it at ai.verticecriativo.pt.

Before this — and still — I spent 15+ years as an audio engineer in broadcast, FOH and mastering. That matters more than it sounds: both jobs are about signal chains, and about not trusting a meter you have not calibrated yourself.

I work on how a machine's claim about its own work can be checked by a stranger. Mostly through the trustless-ai org, with a small working group across four countries.

Ethereum ERC drafts I author or co-author (all under review — none merged yet)

Also contributing to ERC-8354 (confidential policy verdicts) and co-authoring the Composed Attestation Note, which composes with ERC-8004 and ERC-8263.

Things that run

• Cross-Reference Console — four independent operators re-derive the same claims with different code. An agreement only counts when the implementations are demonstrably distinct; the software refuses agreement it cannot substantiate, and "could not check" is never a pass.
• recompute-kit — the recomputation primitives, installable and runnable offline by anyone.
• ccip-router — CCIP-Read gateway mesh, three nodes live.
