the problem with commercial real estate data is that it's fragmented (many players, each aggregating the same/similar information for their own purposes). as a result, there's at least a double cost - one to collect the data, and one to verify it, multiplied by the number of players. this leads to many implications, including information gray areas and institutional players exploiting insider insights.

today, our platform solves the problem of data collection (we act as an integrator), but the missing puzzle is verification. 

a few years ago, I was working on the idea of "property digital passports" - we built a theoretical model, the idea that each property could have its nft-like token with its history records chained in it (so there shouldn't be a need to double verify information that has been confirmed in the past).

didn't develop it further because we needed to put more effort into the core business, but... when I came across nostr, I was very excited because the concept is very close to what we were looking for.

to answer your question if we will use nostr, i still need to learn more and understand it better, but I'm very optimistic.
