Configurable Asset Privacy and Proof-Carrying Disclosures

Ben Fisch

5.5.23

Configurable Asset Privacy for Ethereum (CAPE) is a smart-contract application that enables wrapping of Ethereum assets, as well as creation of new assets, with flexible privacy policies. Ben Fisch (Yale and Espresso Systems) explains the basics of CAPE and shows how creators of digital assets may configure a viewing policy, designating auditors that can decrypt select information about transactions under certain conditions. An extension to CAPE, based on decentralized private computation, supports arbitrary user-defined policies. Lastly, Ben presents an application of proof-carrying data (PCD) to disclosing information about the provenance of assets in shielded pools. In theory, PCDs can be used to achieve the same level of sanction enforcement without blocking the usage of shielded pools and/or eroding their overall functionality.
