如何在私有网络的底层区块链中设置系统属性？

Question

I am deploying my own private blockchain using the substrate code. In which how to set the token decimals and token symbol while deploying it?

Answer 1

These parameters are set in the node's chain_spec.rs in the template code and an example from polkadot code that ingests a JSON file for a specific chain ( examples )

To get this generated for you automatically that you can then customize, build the node and then follow the flowoutlined in the cumulus workshop to get a plain chainspec, edit as you see fit, and then generate a custom final one that you can use when starting your nodes.
