an example of the problem I see, that's simpler to explain. lets say you have a high resolution image, and you want to generate a thumbnail, but also be able to cryptographically prove that the thumbnail really is of the image. That would be pretty awesome! but you have to make a hash function that is also a image scaling function, that's new computer science. I would bet it's possible to create an algorithm like this, but I'd think it would be very application/format specific, unlike a hash function, where you just hash the bytes in an image (for example) but it has zero relation to the hash of resized image.
Okay so the idea here is that you have a high level aggregation, but also, you can zoom into a area and get more detail, and also "prove" that it is part of the large scale data.
The biggest problem I see, is that the aggregation algorithm (say, you have the full detail street view with footpaths, power lines, where underground pipes are, etc) then when you zoom out, how to decide which things get dropped? and how are things merged? I think it would be quite a complicated algorithm to develop, probably with a lot of application specific tuneables. But if the aggregation levels are cryptographically hashed, now you can change the aggregation algorithm.
But I do think this would be a really cool research area! In my own very vague day dreams about this sort of thing, I imagined that the zoomed out layers would be generated more from a consensus sort of process... something like you'd vote (or delegate) on the appearance of the large scale view)
based on what I read about it here grand jury resister's oath it seems like maybe you do understand it @Clinton.
it seems like once upon a time, anyone could bring an accusation to a grand jury:
In the early decades of the United States grand juries played a major role in public matters. During that period counties followed the traditional practice of requiring all decisions be made by at least twelve of the grand jurors, (e.g., for a twenty-three-person grand jury, twelve people would constitute a bare majority). Any citizen could bring a matter before a grand jury directly, from a public work that needed repair, to the delinquent conduct of a public official, to a complaint of a crime, and grand juries could conduct their own investigations. In that era most criminal prosecutions were conducted by private parties, either a law enforcement officer, a lawyer hired by a crime victim or his family, or even by laymen. A layman could bring a bill of indictment to the grand jury; if the grand jury found there was sufficient evidence for a trial, that the act was a crime under law, and that the court had jurisdiction, it would return the indictment to the complainant.
It seems like somewhere along it morphed into a different thing. Most other common law countries had grand juries previously but all but the United States and Liberia have abolished them.
