OP_CAT Enables Winternitz Signatures

In a recent update shared on the Bitcoin Development Mailing List, Jonas Nick highlighted a correction regarding the optimal checksum value for a specific parameter (w = 16). Initially, it was suggested that the optimal checksum should be 512. However, upon further review, Jonas corrected this figure to 480, explaining the miscalculation stemmed from an oversight in calculating the average of the range [0, 16), which is actually 7.5, not 8 as previously assumed. This correction serves as a vital clarification for those involved in the development and optimisation processes within the Bitcoin community, ensuring accurate implementation and understanding of checksum values in their work.
