Synchronize Chain Data

Open terminal 1：

run our node with `--rpc--methods=unsafe` which allows us inserting our maintainer account into our node.

mkdir jaz-node-data

./jaz-node --base-path ./jaz-node-data --pruning=archive --rpc-methods=unsafe --unsafe-ws-external --unsafe-rpc-external

please MAKE SURE your node is running with --rpc-methods=unsafe flag, because the operation after will generate keys into your local storage offchain.

Open another terminal 2：

curl -X POST -H "Content-type: application/json"  http://127.0.0.1:9933 -d '
{
  "method": "author_rotateKeys",
  "jsonrpc": "2.0",
  "id": 1,
  "params": []
