Title: Search by Address
Post by: mjc on December 27, 2012, 03:11:01 AM

I've been searching how to solve this problem, but keep running into the same responses. It might be that is just the only way to resolve this. I thought, before I give up my search I'd reach out here.

I'm looking for a way to search, given a public Bitcoin Address, for all the transactions it is part of.

I'm familiar with

http://blockexplorer.com/address/<address>

I'm looking however for something that will give me the raw results, much in the same way as

http://blockexplorer.com/rawblock/<block>

Does for blocks. I'm writing a Maltego transform to visualize transactions. I started this a few weeks but got a busy with the Holidays. I was able to transform a Block into transactions. This is only somewhat useful. I'm really looking to be able to see related transactions for a given address.

If there is no web API, any suggestions of a good java API for extracting from the Berkley db create by the bitcoin-qt?

Thanks,
Michael

I did find

http://blockexplorer.com/q/mytransactions/<address>

this might work.

not saying it contains what you're looking for, but have you read this?

Are you only looking for a service (API) that ofers this?

Yes I did, when I first started this. Thanks for posting it as I had misplaced the link and that will come in very handy.

Maltego is a semantic web (Web 3.0) Tool that allows a visual representation of searches. Essentially what it allows me to do is to define a set of Entities like:

Transaction
Block
Address

Then for each Entity I can create Transforms. For instance an Address transform might be Get Associated Addresses. This is the one I'm working on now. It will query, something and return with a set of addresses that either sent that address BTC or that received BTC from that address.

I know tools like this exist, as I see pictures in articles all the time that show these relationships visually. Since I'm familiar with Maltego I decided to use it. Some of the pictures actually look like they might come from Maltego.

Once I have something worth uploading I'll start a google code project and anyone can have a look.

Actually after further review, this did have a query that I think might be easier to use:

http://blockchain.info/rawaddr/<address>

Thanks.

Have a look at Electrum source code. It uses an "address history" API on the Electrum server. So with a simple JSON call to any Electrum server you would get back a detailed transaction history for a given address.

Below an excerpt from the API offered by the bitsofproof supernode.

The database it maintains is also queryable if you use the SQL option.
Both LevelDB and relational storage options are optimized to answer below APIs that are RMI calls to the server.

Code:

         /**
	 * get transaction outputs that could be spent by the adresses
	 * 
	 * @param address
	 * @return list of outputs, eventually empty
	 */
	public List<TransactionOutput> getBalance (List<String> address);

	/**
	 * get account statement
	 * 
	 * @param addresses
	 * @param from
	 *            - unix time point the account statement should start from
	 * @return
	 */
	public AccountStatement getAccountStatement (List<String> addresses, long from);
