The way it actually works?
I believe the best means ahead is to cling firmly to the reality that addresses are a fiction. They’re an sometimes handy approach to seek advice from a locking script. An excessive amount of deal with addresses will lead you away from the underlying fact.
If you consider locking scripts as an alternative of addresses, I might count on issues to turn out to be 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 non-public key. There are a number of totally different commonplace locking scripts during which a public secret’s used.
An proprietor of a key-pair can individually observe transactions that comprise particular however distinct varieties of locking scripts involving the identical underlying keys.
I consider blockchain explorers principally index by summary of locking script – in order that they produce separate lists of transactions for every distinctive locking script.
the transaction lists from all [the different address types] are totally different. How can it’s, if the non-public key is similar?
The reality is that transactions do not pay to a selected non-public key, they pay to anybody who can unlock a locking script. Typically that unlocking would possibly contain no non-public keys, generally which may contain a number of non-public keys.
Moreover, some varieties of locking script disclose a public key however some dont. So an explorer would not know if some varieties of transactio-output contain the identical key pair. So the explorer cannot reliably group transaction-outputs by widespread non-public key.
