Actually we can’t - i do not know the way to bind ip address and validator name (exist way to get it, but it work only if you validation node owner, and do not work for foreign adnl addresess), i do not know why another man add this point in his requirements!
validators should have the right to anonymity
I agree and, as i understand from documentation, system of adnl addresses was implemented also to hide ip information from other.
I know only one way to fetch geo ip information - is parse traffic data.
This information available for other network parcipant and for provider. That is mean, that we can use common information, that already public as fact, but with more useful visualization.
Ok, I’ll try to explain my thoughts in more detail.
The solution should collect data from the moment it was launched.
The validating session that was at the time of its start will be the first. Then the second, third, etc.
Adnl address + validation session timeframe define the validator. He can find himself in this. He can give feedback on whether his coordinates were determined correctly or not. In other words, it gives complete certainty (which I think is very important).
And I think it’s completely wrong to make a solution with coordinates but without names of data centers. These two parameters complement each other perfectly. They give twice as much information at once.
To do a separate competition for data centers is a waste of crystals. Why not combine?
About validation session: I still cant find information about validation session, are you sure that this information available for everyone. Aspecialy information about other validators, that working right now? Only if you sure, that it is available for other contest parcipants, we can add it to requirements.
About datacenter name: For geolocation exist special open sources databases, (GeoLite2). i never mat such database for data center info. You propose use external service, is it free? It is has any license limitation (for example for commercial use)? Or exist open source database, that available for everyone?
