Google Earth doesn't generate any revenue.Any idea about how such project can generate revenue?Ads shown here and there might do the work,but the user experience will suffer from this.
Same way how they are making money out of
google maps, and there is a lot of money.
But the whole blockchain thing is just useless at this point, it will take such huge resources to store all the data in full nodes it will be decentralized only in name, in reality, there will be just a few servers with a full copy of it.
Storing those images in a P2P fashion something like Torrents seems fine for whatever your use case is but don't know how or why blockchain would be a necessity here?
None, but this is the trend now, everything needs to be done via a blockchain, the madness will strat again just like in 2017 when there was a blockchain project for every activity known to man. The old SETI@home would do far better than any blockchain for this, there are a few websites that use it combined with bittorrent serving millions of pictures a day for years, one of them, the notorious ehentai is currently doing 11Gb/s in trafic, pretty impressive for just pictures.
