Blockchain Scalpel is a lightweight script for parsing raw blkXXXXX.dat files of the Bitcoin blockchain database.

The tool provides direct access to blockchain data stored on disk and allows exploring the main database as close as possible to its original binary representation.

The parser is also compatible with many altcoins with minimal adjustments.
