Blindbitd leverages taproot outputs from a block as inputs for its scanning function, showcasing an innovative approach to handling transactions.

This methodology circumvents the need for labeling tweaks with their respective transaction IDs (txid), a common practice in blockchain operations. Instead, it necessitates scanning through all the outputs of a block to identify relevant tweaks. This process is facilitated by maintaining a mapping between ScriptPubKey and the tweak computed during an earlier step. Although this does not provide a direct association between txid and tweak, it enables an indirect method to ascertain a transaction's tweak by examining its outputs. This strategy significantly reduces the necessity to scan every output of a block for each tweak, bypassing the requirement for directly tagging tweaks with their txid. Nevertheless, it introduces the need for effectively grouping the outputs to streamline the identification process. This approach reflects a nuanced understanding of blockchain technology, offering a potentially more efficient way to manage and verify transactions without compromising on the integrity or security of the data involved.
