Description: Sikorka is presented at Devcon 3 as a proof-of-presence system for blockchain applications, letting a device or user attest cryptographically that they were at a given place at a given time. The talk covers how these presence attestations can anchor location-dependent smart contracts and event check-ins without relying on a centralized verifier.
