Summary

Extractor by Hacken’s Canton Monitor is an open-source, participant-local monitoring and risk-scoring stack built specifically for the Canton ecosystem. Designed to respect Canton’s strict sub-transaction privacy model, the monitor connects to the Ledger API and Admin API to run privacy-aware real-time detectors and score interacting party risk. It emits reusable, standardized alerts for validators, app providers, custodians, auditors, and compliance teams.

I'd support this proposal.
Canton presents a dilemma for typical compliance and AML products that rely primarily (or entirely) on public data: Data must be revealed to them in order for them to perform the relevant analysis.

The two practical paths forward are to either query private data via a TEE to extract the relevant analyses (and perhaps, in the future, rely on ZKPs to prove certain important aggregates or events), or for node operators to run a node-local compliance / AML / risk scoring solution, providing local access to private data.
