A quantum resistance script only using op_ctv/op_txhash and no new signatures

The conversation delves into the intricacies of implementing a new version of SegWit, focusing on the conditions under which a key spend is permitted. The proposal suggests that a key spend should only be allowed if there is no script tree present. Alternatively, it considers a scenario where only the presence of a script tree is permissible. This discussion highlights the need for careful consideration in updating SegWit versions to ensure compatibility and security within blockchain operations. The emphasis lies on the technical aspects of blockchain architecture, specifically how transactions and scripts are handled and validated. Understanding these proposals is crucial for developers working on blockchain technology, as they directly impact transaction processing and validation rules.
