ecdsa-dump-bitcoin

Note: This is a fork of rusty-blockparser

Dump bitcoin signatures and original messages

Changes from upstream

• Added sigdump callback

Building

All you need is Rust, which can be installed using rustup.

cargo build --release

It is important to build with --release, for better performance!

Usage

cargo run --release -- sigdump --help

USAGE:
    rusty-blockparser sigdump <dump-folder> <bitcoin-folder>

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information

ARGS:
    <dump-folder>       Folder to store csv files
    <bitcoin-folder>    Path to the .bitcoin folder

Example

To dump all ecdsa signatures and original messages from the Bitcoin chain, do the following.

First install Bitcoin core and run it with transaction indexing enabled:

bitcoin-qt -txindex=1

During the first run, make sure to note where the bitcoin folder is. By default, it will be in ~/.bitcoin. Make sure to disable chain pruning when asked. There may be a checkbox to disable on first run of bitcoin-qt.

To dump signatures and messages that were synced so far, using the bitcoin folder and to dump them in the dump folder, use the sigdump callback as in the following example:

$ cargo run --release -- sigdump ./dump-folder ~/.bitcoin

Dumped all 1 blocks:
        -> transactions:         1

        -> outputs:              1
[8:41:53 UTC] INFO - main: Fin.

A CSV file will be created in the dump folder. This output file will contain, on each line:

r;s;pubkey;txid;message_hash;block_time
