New Post Quantum Bitcoin Proposal using WInternitz + Lamport auth chains

The email raises inquiries about a specific cryptographic authorization chain associated with the Lamport schema and its application in blockchain transactions. The core of the discussion revolves around whether output scripts in this model commit to a single Winternitz public key or if they encompass the entire authorization chain. The distinction is crucial for practical applications where multiple signatures might be required from an output script. This necessity arises in scenarios such as unsuccessful transaction attempts requiring adjustments in transaction fees or transactions that involve inputs from multiple users.

Further clarity is sought on the mechanics of the Lamport authorization chain. Each link of this chain permits the upload of one Winternitz public key, which subsequently can be employed to authenticate the Winternitz signature tied to a message. However, the implications of this setup on blockchain transaction practices, particularly its flexibility and security in situations demanding numerous signatures, remain unclear. There appears to be a need for a deeper understanding or a more detailed explanation of how these elements interact within broader transactional contexts, ensuring robustness against potential defects or changes in transaction participants.
