Dump ECDSA signatures, original message, etc. of all transactions on the Ethereum blockchain.
- Poetry, see Installation instructions
- Python 3.7+
- An Ethereum node running with the JSON RPC service accessible at http://localhost:8545
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.
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
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.

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 .
