Designing systems for notarial digital trust: traceability, contract analysis, compliance and blockchain architectures.
My role
IT Architecture Advisor at Université Laval, I lead the technology program of the Research Chair in Smart Contracts, in collaboration with the Chambre des notaires du Québec. The program covers three projects: the CFN, the GPSN and the design of the notarial blockchain.
Projects
The notarial sector handles files and deeds that must remain traceable, verifiable and governed throughout their lifecycle. The need was not merely to digitize a process, but to create a trust foundation capable of supporting authentication, auditing and proof of integrity.
The project explores a notarial infrastructure where key events in a file can be tracked, controlled and accessed by the right parties within an institutional framework.
Regulatory bodies must be able to understand what happened, when, by whom and in what context, without relying solely on declarations or fragmented systems. The primary need is the capacity for control and verification.
The platform aims to support compliance by providing better visibility into regulated operations, with traceability and integrity logic tailored to the notarial context.
Contract analysis is time-consuming and often relies on manual review that is difficult to standardize. The need was to help identify, classify and compare contractual clauses in a more structured way.
The module transforms legal documents into more actionable analysis objects, supporting research, clause evaluation and contract comprehension.
