<p>On blockchain.info I saw a transaction labeled as "No inputs (newly generated coins)". Are these new coins generated from mining?</p>

It seems like you're asking two different questions. Are you asking about where coins come from, or how the number of confirmations are determined?

# Transaction marked as "Newly generated coins" on Blockchain.info

(Asked by: username_0 on 2015-05-30)

On blockchain.info I saw a transaction labeled as "No inputs (newly generated coins)". Are these new coins generated from mining?

How come that such a transaction can have 30 confirmations, while others only have six confirmations?

No inputs means that the coins are coming from a coinbase transaction, that is, they were only moved "once", when they were created.

Transactions will have different numbers of confirmations based on how recently the funds were moved.
