OP_CAT by adding a general purpose way to concatenate stack values would overcome this limitation and greatly increase the functionality of tapscript. +Bitcoin tapscript lacks a general purpose way of combining objects on the stack restricting the expressiveness and power of tapscript.

OP_CAT by adding a general purpose way to concatenate stack values would overcome this limitation and greatly increase the functionality of tapscript. OP_CAT aims to expands the toolbox of the tapscript developer with a simple, modular and useful opcode in the spirit of Unix R. Pike and B.

To demonstrate the usefulness of OP_CAT below we provide a non-exhaustive list of some usecases that OP_CAT would enable: -- cgit v1.2.3
