Unspendable keys in descriptors

It is outlined that if the hex chain code is calculated deterministically in accordance with certain specifications, the method would be consistent with the strategy suggested. This highlights an essential aspect of cryptographic security—the necessity for good entropy in generating an unspendable key. However, it clarifies that while high-quality entropy is required, it does not need to be freshly generated for each instance. The emphasis is on the use of existing, reliable entropy rather than the constant creation of new entropy sources.
