I’ve been trying to build location-based dapps since ETHDenver 2018. One recurring need: a way of showing where something is. Delving into the complexities of proving the “where” on the Internet has revealed deep challenges and major trust assumptions.

The problem is worth working on — from cartography to compliance, the credibility of location data underpins countless aspects of the information age.

To me, Web3 is our response to flaws we see in the way the Internet works. Web3 isn’t a collection of tools of platforms, but a set of design principles that reflect values such as privacy, user control and interoperability. I've been trying to build location-based apps that align with these principles.

On the topic of location proofs, there’s significant prior art: - @foamspace's dynamic proof of location - zkMaps' work on zero-knowledge location proofs - Witness Chain’s geolocation strategy using network latency (h/t @justindrake) - EASIER group’s development of spatial data storage + access tools on @ipfs
