Pre-Requisite Create Account and Node Key, Add account to network

Adding a new validator into ledger

$ docker ps
## make sure no cord process is running
$ docker run -p 9944:9944 --name cord-validator --detach -v $(pwd):/data dhiway/cord:0.9.0 --name Confidex-${ORG_ID}-validator --chain /data/confidex-alpha.json  --node-key-file /data/node.key --base-path /data --unsafe-rpc-external --validator --pruning=archive

$(pwd) - Current Working Directory ORG_ID - Enter your organisation name here - Ex:'Confidex'

More information on what are the parameters to add for running different type of nodes are present in CORD Documentation.

NOTE: A node which started without --pruning=archive, you may need to perform docker run -v $(pwd):/data dhiway/cord:0.9.0 purge-chain --chain /data/confidex-alpha.json --base-path /data before running this.

For becoming 'Validator', there are 2 important steps:

  1. set the 'session' keys in the validator process.
  2. needs approval for the given account to be added as the 'authorityMembership'.

After starting the process, one needs to do a 'generate-session-keys' from the secret of the account generated above.

docker run -i -v $(pwd):/data dhiway/cord:0.9.0 key generate-session-keys --chain /data/confidex-alpha.json  --base-path /data  --suri $SECRET

Once the session keys are generated, one needs to set the session keys using RPC with respective node.

$ export SESSIONKEYS=$('Session Keys:' field from above)
$ git clone https://github.com/dhiway/cord-session-setkey
$ cd cord-session-setkey
$ yarn
$ yarn set-key
