Yes if you should check the mining pools address you'll see the coins sitting there however it doesn't have an input and output since the coins were not spent by a transaction. However the miners coins will have a transaction hash because it is a reference to the origin of the coin and when I mean origin I'm referring to POW and timestamp data.
The POW data tells where the coins come from this is to prevent any coin from being faked and spent on the network. The timestamp shows the time and date about the origins of the coins.
Great. I get what you are saying, and thank you to all of you who responded!
I don't know why you chose to highlight that particular reply but it's "
not great" since it misleading actually.
-Miner's coins (
UTXO) have input (
coinbase) which has a special scriptSig of their "
creative design" (
names, extra nonce, etc.) but must contain the block height.
And of course output(
s) just like a regular transaction, which is shown as their bitcoin address(
es) and OP_Return data in blockexplorers.
Perhaps she's talking about the coinbase input; however, when you say "
coins", you're talking about "
UTXO" (
Unspent Transaction Output) which is the coinbase transaction's output.
-The coinbase transaction's hash doesn't represent POW or timestamp aside from the
HASH256 (
SHA256 x2) hash of its serialized transaction data.
Its TXID is the same for legacy, but for for SegWit, the Witness data are excluded when hashing. Both should be in
little-endian order.
There's no timestamp in a coinbase transaction or "
POW Data" whatever that means,
Perhaps she's talking about the timestamp in the "
block header" and the block header's hash which are in the block instead.
-It's part of the Bitcoin protocol which is the only requirement to tell "
where the coins came from" is if it's in the first transaction of the block indicating that it's a coinbase input, it's valid as long as it's in a valid block and not breaking any consensus rules.
