Introducing Provable Object Data

Duration: 00:28:08

Speaker: Andrew Twyman

Type: Talk

Expertise: Beginner

Event: Devcon

Date: Nov 2024

Built on learnings from experimental projects like Zupass, Provable Object Data (POD) is a new format with open-source libraries for any app to issue verifiable data, and make ZK proofs of claims about that data. PODs allow arbitrary key/value data to be signed and distributed. Flexible proofs about PODs can be created using a highly-configurable family of General Purpose Circuits (GPCs), without app-specific circuits or trusted setup. This talk will focus on POD and GPC motivation and design.
