Libbitcoin for Core people

Libbitcoin introduces a significant optimization by not verifying the confirmability of transactions that fall below a certain milestone. This approach assumes that the inputs for these transactions are both existing and unspent, foregoing the usual checks that can slow down the process. This method is key to enhancing the speed of transaction processing within the system. However, this detail might not be immediately apparent upon initial reading, and there seems to be a need for clearer communication regarding this mechanism. Clarification on this aspect could improve understanding and potentially lead to amendments in the original post (OP) to accurately represent what Libbitcoin accomplishes with this strategy.
