The thesis
GuzPicad is a two-person collaboration with Andy Guzman, a Costa Rican privacy-and-cryptography researcher (the name is a portmanteau of ours). It's a working namespace at the intersection of regulated financial markets, securities tokenization, and zero-knowledge cryptography. The flagship effort is a proposal and pilot to issue, trade, and settle tokenized securities on public-blockchain rails with a property most systems get wrong: private from the participants, but visible to the regulators who are supposed to see. It's framed as two locals contributing expertise to their own country's market — not a vendor pitch.
What I do here
I bring the market-structure and regulatory framing and run the institutional side — which public body should host a pilot, how supervisors coordinate, and the engagement itself. Andy owns the zero-knowledge cryptography and the privacy tooling. I draft and iterate the proposal documents and manage the relationship with the regulator.
What's built
- ◦A formal proposal, iterated through versions — reframed from a regulatory "sandbox" into an industrial pilot, with a public financial-innovation center as the institutional home and an inter-supervisor coordination layer.
- ◦A defined technical architecture — LACChain (Hyperledger Besu) as the network; ERC-3643 as the compliance-token standard for programmatic KYC and transfer rules; W3C decentralized identifiers and zero-knowledge credentials with selective-disclosure proofs and viewing keys that let designated regulators see what other participants cannot; and integration with the national payment system for settlement.
- ◦A scope landed on the full securities lifecycle — primary issuance, secondary trading, and atomic delivery-versus-payment settlement, with DvP (no counterparty risk) as the core value proposition.
The design choice that anchors it: it's built explicitly to fix the failure mode that sank a prior major regulated-tokenization effort, where data was either hidden from regulators or exposed to everyone. ZK credentials with regulator viewing keys thread that needle.
Where it stands
Past the idea stage. The first technical meeting with the regulator is done, scope is confirmed at the full lifecycle, and the current proposal is in review. Next is a process-mapping workshop with the regulated actors and confirming the institutional home.
Nearby stars
The most experimental star — distinct from the sports and energy work. It lives in the Alpicat brain collection for tooling, but it's jointly owned with Andy, who's also a partner in MentorHood.
