in any case what exactly is it that you are trying to do that requires a personal indexed blockchain because it doesn't seem like something that any normal use case would demand?
it's not.... it's a deep learning data correlation project I am working on with several people.... I see patterns myself, but can't make sense of them... Given enough data and GPU power, I think answers could be found.
We have already gotten some good results in initial testing, but the lack of being able to send ~100+ requests per minute to lets say, blockchain.info.... per machine... really slows things down by half, per machine per IP. For these services, blockchain.info has the most open free-API data allotment; I can get in a solid 1 request per minute if I do not stop. If I breech that, they will roll in fast, but each IP's allotment of un-timed replies are limited.
Most projects for databasing the blockchain's contents I have seen only catalog TXIO, and if you would like to search for any specifics to an address's balance, or amount of tx's rec'd/sent from/to that address, you would have to rescan the blockchain each time individually for each known address... and, that is retarded to do.... like, seriously retarded.
I'll look into bitcoin-abe.... see if it comes close to what i'm looking for.
I know other groups have done it for other reasons. For example there is that pool of people who solely generate pubkeys/privkeys just to see if there's a balance... and they keep a live lookup table of just pubaddress and balance to do so.
