The way it actually works?
I feel the best approach ahead is to cling firmly to the reality that addresses are a fiction. They’re an often handy solution to discuss with a locking script. An excessive amount of concentrate on addresses will lead you away from the underlying reality.
If you consider locking scripts as an alternative of addresses, I might count on issues to change into clearer.
From one pair of private-key and public-key, there are numerous methods of utilizing the general public key to assemble various kinds of locking script that may be unlocked utilizing the personal key. There are a number of completely different normal locking scripts through which a public key’s used.
An proprietor of a key-pair can individually observe transactions that include particular however distinct forms of locking scripts involving the identical underlying keys.
I imagine blockchain explorers principally index by summary of locking script – so that they produce separate lists of transactions for every distinctive locking script.
the transaction lists from all [the different address types] are completely different. How can or not it’s, if the personal key is similar?
The reality is that transactions do not pay to a selected personal key, they pay to anybody who can unlock a locking script. Generally that unlocking would possibly contain no personal keys, generally that may contain a number of personal keys.
Moreover, some forms of locking script disclose a public key however some dont. So an explorer does not know if some forms of transactio-output contain the identical key pair. So the explorer cannot reliably group transaction-outputs by frequent personal key.
