Getting people to capture real-world data is one thing. Making buyers trust what they receive is another. This is where @vangrid_io takes an interesting approach. Every capture gets a digital fingerprint containing a content hash, approximate location, and timestamp. These records are grouped into a Merkle tree, with the root anchored on Base through the Ethereum Attestation Service. Faces and license plates are also blurred on the device before upload. Why does this matter? A buyer doesn’t have to rely entirely on the platform’s word. They can inspect the attestation transaction and verify the record behind a capture. That adds a layer of accountability to how physical data is requested, collected, and paid for. The web and Android apps have been live since July, and captures are already being attested onchain. I like the focus on making real-world data verifiable because trust will be essential if crowdsourced physical data is going to support the growth of Physical AI.
