txNew.vout[0].scriptPubKey
public ECDSA key

What is the purpose of this public key in the main.cpp? what is suppose to do? Where do you keep the private part of it? Does private key ever get used?

It is used to generate the genesis block, from which all other blocks ultimately derive. Presumably Satoshi has the private key for that txout, but it's unspendable anyway.

Thanks, so assuming you create alt coin, just create key pair & update public key part of it here & forget about the private key as it will not be needed in the future, like updating to new version or version control etc. No need to store private key as it will never be used?
