README.md

Code in this repo has not been tested in a while, so it may not work with latest versions of Parity and Geth. Feel free to submit a PR if you identify fixes.

to Parity one, which should enable the two to connect to each other. For best effects use the "config" field in Geth spec as seen in the Ropsten testnet spec.

Usage

If you do not have Cargo, best to use Rustup.

git clone https://github.com/keorn/parity-spec.git
cd parity-spec
cargo run -- geth-spec.json

Where geth-spec.json is your Geth spec file.

The resulting converted file will be printed to the console, then you can save it as json file (for example parity-spec.json).

Finally it can be used in Parity with parity --chain parity-spec.json.
