I presume the Blockchain is audited frequently by a thousand parsers and what not,

If any of you have an audit that runs frequently...

Every tx and every block distributed by the p2p network is "audited" by every node on the network before being passed along. Nodes don't trust other nodes. Each node verifies the data it receives before accepting the information. Information that is wrong is discarded.

Do all transaction inputs and outputs always sum as expected, are there any exceptions, if so why

Inputs and outputs do not always match. The differences between these are the fees. Inputs >= outputs. Input - Output = tx fee (goes to the miner of the block in which the tx is included).

Also the block mining reward (25BTC currently) transaction has no inputs as 25BTC is created in these tx.

a page that publishes the results i would appreciate it, thanks!

I think others have addressed this part of your question more.

My advice here would be get a db dump of the blockchain from webbtc and try do your queries against this. Parsing and interpeting the blockchain solely for one report can take a while (days, weeks..), though depends what you're using..the data you need probably be done without parsing it by hand

This recently published analysis might answer some of your questions:

Also see associated Coindesk article: http://www.coindesk.com/analysis-around-70-bitcoins-dormant-least-six-months/

If that's not sufficient, I guess you have to break out your coding skillz. Wink

I presume the Blockchain is audited frequently by a thousand parsers and what not, but it seems most of the data I find is simply transaction trends, volume, days destroyed, et cetera.

Things that I would want to know:

Do all transaction inputs and outputs always sum as expected, are there any exceptions, if so why
Total count of coins in the blockchain, verified by the blockchain itself
Number of coins greater than 30 days old that re untouched since they were mined
Number of addresses untouched for more than a year, more than two years, three years, four years

If any of you have an audit that runs frequently and a page that publishes the results i would appreciate it, thanks!

The blockchain is quite large. If you know how to code, making a parser should be pretty straightforward but resource intensive.
