ecdsa-dump-ethereum

Python 3.7+ License: GPL v3

Dump ECDSA signatures, original message, etc. of all transactions on the Ethereum blockchain.

Requirements

As per Nodes and Clients, since "The Merge", to obtain a fully synced node, both an execution client, such as geth, and a consensus client, such as lighthouse is required.

As of October 2022, the full chain (full node, not archive node) requires about 1.6 TB of storage. Doing a full sync from scratch to block 15'800'000 will take about 3 weeks.

Running the Ethereum node

To start geth:

geth --syncmode full --http

To start lighthouse:

lighthouse bn --execution-endpoint http://localhost:8551 --execution-jwt ~/.ethereum/geth/jwtsecret --http --checkpoint-sync-url https://mainnet.checkpoint.sigp.io

Usage

To dump the signatures and messages from block 0 to 70000 as CSV, run:

poetry install
poetry run python main.py -o output_file.csv --end-block 70000

The output file will contain on each line:

source_address;r;s;pubkey;txid;message_hash;block_time

For more options and help:

$ poetry run python main.py -h                
usage: ecdsa-dump-ethereum [-h] [--start-block START_BLOCK] [--end-block END_BLOCK] [--host HOST] --output OUTPUT_PATH

Dump ECDSA signatures, original message, etc. of all transactions on the Ethereum blockchain.

options:
  -h, --help            show this help message and exit
  --start-block START_BLOCK, -s START_BLOCK
                        Number of the block to start dumping from
  --end-block END_BLOCK, -e END_BLOCK
                        Number of the block to stop dumping from (included)
  --host HOST           The Ethereum node JSON RPC service to connect to. Defaults to http://localhost:8545 .
  --output OUTPUT_PATH, -o OUTPUT_PATH
                        Path to the output file to dump to
