What is the eosio account re EOS blockchains

Question

I changed the "producer-name" to another value but then the blockchain doesn't sign transactions and it sits idle. This is why I'm confused about "eosio." Its key is configured in the config.ini but it doesn't appear that you can change the "producer-name," which is fine, but then why have a "-p" cmd. line parameter? It's just not making sense to me.

Answer 1

Its private key is stored at config.ini

# Tuple of [public key, WIF private key] (may specify multiple times) (eosio::producer_plugin) private-key = ["EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV","5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3"]

The second value is the private key.
