Thesis
Secrecy between peers, visibility for those with a legal mandate. Not by breaking in — by design.
Privacy that doesn't blind the regulator.
I work on the problem of getting institutions that don't trust one another to agree on the same record, without exposing themselves to each other and without leaving the supervisor in the dark.
I built Bywise — a blockchain written from scratch, not a fork, with a data-sharding architecture that gains capacity with every new node instead of losing it. The code is open source under the MIT licence.
Out of it came ChainXS, developed in a joint venture with Bloxs for the Brazilian financial market. There I designed an auditable privacy layer for a Regulated Liability Network: each user receives fresh addresses for every operation, peers cannot link them to one another, and whoever holds a legal mandate sees the whole tree without being able to sign anything on anyone's behalf. The key to the statement, not the key to the vault.
Before that came fifteen years on the same problem in other clothes — from restaurant tills that had to agree in real time to traceability in logistics, precious metals and exchange proof-of-funds.

Lien reconciliation: the privacy requirement that survives a change of technology
The DREX pilot was shut down and the market read it as a verdict on blockchain. It was a verdict on a requirement specification — and in a central registry the same defect reappears in the query, not in the data.
