Title: What would be the best way to get the balance of an address? Post by: Elwar on August 10, 2012, 09:16:22 PM I am looking to check an address to see if it is empty and if not empty, check to see how many bitcoins the address contains.
Would I be able to do this with a call from bitcoinj or would I need to add up transactions through the blockchain or what? Title: Re: What would be the best way to get the balance of an address?

There is a service that might help, if you weren't aware of it: - http://btcbalance.net Also, via API: - https://blockexplorer.com/q/addressbalance/<address> - http://blockchain.info/q/addressbalance/<address> Title: Re: What would be the best way to get the balance of an address?

I cannot rely on a third party. Title: Re: What would be the best way to get the balance of an address?

Check out blockparser (https://github.com/znort987/blockparser). The command would be something like blockparser tally <address>. Requires synced blockchain from original client, Ubuntu x86-64. There may be a way to query arbitrary addresses through the original client's RPC commands, too. Title: Re: What would be the best way to get the balance of an address?
