Greetings!

Since the last research update, IC3 researchers proposed a new file geolocation system, won a Facebook Fellowship, and more! Please register for the 2021 IC3 Blockchain Summer Camp (partial schedule below).
UPCOMING IC3 EVENTS
Join us for the 6th Annual IC3 Blockchain Summer Camp! This seven day experience will be hosted virtually this year and feature talks, panels, tutorials, and a hackathon for IC3 members. Topics will include DeFi, Cryptography, Layer 2, Privacy, and more!
A partial draft of our 2021 schedule.
NEW RESEARCH
The authors propose GoAT, a practical Proof of Geo-Retrievability (PoGeoRet) that enables proving that a file is located within a strict geographic boundary. Using PoGeoRet, one can trivially construct a Proof of Replication (PoRep) by proving that a file is in several distinct geographic regions. Unlike previous geolocation systems that rely on trusted verifiers, GoAT bootstraps using public timestamping servers on the internet that serve as geolocation anchors, tolerating a local threshold of dishonest anchors.
