Title: Open the Blockchain in a Database Post by: rolling on July 30, 2013, 12:53:57 AM Can anyone tell me how to open the blockchain using a database program such as Access? I apparently have the blockchain since I have bitcoin installed but I can not view it in anything but the native program. I tried importing the dat files but couldn't.

Title: Re: Open the Blockchain in a Database Post by: rolling on July 30, 2013, 01:17:14 AM I want the whole blockchain. It would take years viewing 1 block at a time.
Title: Re: Open the Blockchain in a Database Post by: lmn123 on July 30, 2013, 01:31:24 AM Correct me if I'm wrong, but isn't the blockchain stored as plaintext? Can't you just view it by concatenating all the blockXX.dat files in the "~/.bitcoin/blocks" folder and just view them with a text viewer?
Title: Re: Open the Blockchain in a Database Post by: rolling on July 30, 2013, 01:34:44 AM I just get a bunch of scrambled characters.
Title: Re: Open the Blockchain in a Database Post by: lmn123 on July 30, 2013, 11:16:10 AM Shoot I do too. Why did I think those were plaintext? Somebody who knows better will have to help.
Title: Re: Open the Blockchain in a Database Post by: whault on July 30, 2013, 11:46:53 AM The blocks are stored in something called LevelDB, which is already a very capable database format. While you wouldn't have any fun opening it up in Excel (it's 10GB afteral), you can use a python application named Abe to throw it all into a Postgres/MySQL database if you really insist. I would personally advise against it though.
