OpenEthereum (formerly Parity)
Updating OE
✅ Please update to v3.2.5 which contains Berlin hard fork transition and the new enodes: https://github.com/openethereum/openethereum/releases/tag/v3.2.5
✅ Perform a DB migration if your run OE version < v3.2.0
✅ dataDir in chain spec has changed from DaiChain to xdai - manually rename the folder to avoid syncing from genesis.
✅ If your node works on an old version of Parity, you need to convert node's DB to the format compatible with OpenEthereum v3.2.x. You can use this tool https://github.com/openethereum/3.1-db-upgrade-tool
For a non-dev user friendly version, see https://forum.1hive.org/t/run-your-own-local-xdai-node/2875

Linux
Download the latest release from the link above
Make the openethereum file executable by running
chmod u+x openethereumLaunch OpenEthereum:
./openethereum --chain xdai --no-warp
The --no-warp flag is recommended if you want all historical data, but will take much longer to sync. For a faster sync, you do not need to use it. More information on --no-warp
Mac
Download the mac binary.
Open a terminal and navigate to the directory using
cd /path/to/binary/folder/.Make the binary executable by running
chmod +x openethereum.You can now double click on the binary.
Windows Download the binary and double click on it.
For Linux systems:
Ubuntu, Debian
$ apt-get install build-essential cmake libudev-devCentOS
$ yum install libudev-devel$ yum group install "Development Tools"
openethereum --chain xdai --no-warp
--no-warp flag is optional: more information.
If you would like to limit or choose specific bootnodes, you can obtain the bootnodes.txt file from POA github:
git clone -b dai https://github.com/poanetwork/poa-chain-spec.git
enter all supplied enodes for the desired network separated by a comma, no space
openethereum --chain xdai --bootnodes enode://[email protected]:PORT,enode://[email protected]:PORT
You can use Ethereum's JSON-RPC or a JavaScript console.
You can use Remix connected to a local OpenEthereum full node for smart contracts development and deployment. Make sure that Remix is allowed to connect to your node by setting up the right JSON-RPC cors policy.
