Getting list of all transactions and addresses using a daemon

[williamj2543]

Hey, I am doing some cryptocurrency programming, more specifically I am building a block explorer, and I am wondering how would I list all the latest transactions on the network, and how would I get all addresses with a balance greater than 0 (I am trying to make a rich list). I am not necessarily using bitcoin (I am using other altcoins) but the daemon calls are all the same. How would I do this?

Ugh.

Start by parsing the block files to quickly generate your database.  Keep it current with -blocknotify.  To see unconfirmed transactions, either interface with a real node using the p2p protocol, or poll the mempool and iterate the list asking for transaction details.

Yea I was thinking that I would have to use a database of some sort. I think I'm gonna do a loop to index all of the blocks to get all the txs in the database. I'd have to increase the block height every time it is looped ($a++) sort of thing. Is there any way to get info about an address not in my wallet? My txindex is set to 1.

Because other people's interest in that data fills up their pocket.

I think the best bet is to use a flat file, but managing that would require a lot of coding.
