So in this transaction,
90db022100e2ac980643b0b82c0e88ffdfec6b64e3e6ba35e7ba5fdd7d5d6cc8d25c6b241501 is Alice's public key.
And in the output ,
the <pubkeyhash> 404371705fa9bd789a2fcd52d2c580b65d35549d should be the receiver Bob's public key hash?

But the script will verify if <pubKeyHash> is the hash of <pubKey>. How can Alice's public key relate to Bob's, they won't match right?

Thanks, but let's say Alice sends a transaction to Bob using a previous tx from Carol.
then in the example above.

who is the owner of the public key<pubkey>? (90db022100e2ac980643b0b82c0e88ffdfec6b64e3e6ba35e7ba5fdd7d5d6cc8d25c6b241501)

In pay-to-PubkeyHash:
scriptPubKey: OP_DUP OP_HASH160 <pubKeyHash> OP_EQUALVERIFY OP_CHECKSIG
scriptSig: <sig> <pubKey>

what do pubkey and pubKeyHash stand for?

Since the script will check the validity of signature, I guess pubKey is the pubKey of the sender?
But is <pubKeyHash> the hash of receiver's public key?
Then what's the point of checking sender's public key with receiver's? They can't match.

I just want to know the owner of these two keys. Sender or receiver?
