Can blockchain become a trust layer for real-world events?

One thing I've been thinking about recently is that blockchains are great at verifying digital information—but they still struggle to verify physical reality.

For example:

• Did someone actually visit a location?
• Was a delivery completed?
• Did an inspection really happen?
• Can an AI agent prove it interacted with the physical world?

GPS alone isn't enough anymore, and centralized systems require trust.

I've been working on an open protocol called GeoProof that explores using multi-signal verification to generate cryptographically verifiable attestations for real-world events.

The goal isn't to replace existing blockchains, but to provide a reusable verification layer that applications can integrate regardless of which chain they use.

I'd really appreciate feedback on whether this problem is worth solving and whether you think an open protocol is the right approach.
