I’m learning how the Bitcoin addresses era works.
So far as I discovered, a Bitcoin deal with seems within the blockchain solely after it has been concerned in its first transaction. If an deal with has by no means been utilized in any transactions, it is not going to have a presence within the blockchain.
For that reason, Initially, I believed that with out information of the non-public key, there can be no technique to confirm if a given deal with is an accurate hash generated from actual key, or just a random/made-up mixture of characters of the identical size (like a few of these “vanity-addresses”).
Nevertheless, in the present day I found that after I enter a genuinely generated BTC deal with that has by no means been used earlier than (for positive) into the search subject on blockchain.com, the newest shows a message indicating that the deal with is discovered however has no transactions.
To generate addresses, I used bitaddress.org and this python lib, I attempted a number of instances, utilizing each, however the outcomes at all times typically seem like ones above.
Then again, after I change a single character in such an deal with or enter random digits and letters that visually resemble a BTC deal with (together with size) however weren’t generated utilizing the talked about lib/service, blockchain.com states that “Nothing discovered.”
How do the service distinguishes between actual and made-up addresses, on this case?
