The concept introduced revolves around the innovative idea of adding opcode contexts via the script version to enhance Bitcoin script functionalities.

This approach suggests using an opcode that loads a 1 to N byte map, essentially rewriting the mapping from opcode number to the corresponding instruction it signifies. Such a mechanism would theoretically allow for an infinite number of instructions within Bitcoin's scripting language, significantly expanding its capabilities and flexibility.

The proposal highlights the possibility of changing the context multiple times within a single script, with a minimal overhead cost of only two or three bytes. This efficiency in space utilization could offer substantial benefits in terms of script complexity and execution without burdening the blockchain with excessive data.

This idea was shared within the Bitcoin Development Mailing List, indicating its relevance and potential interest to developers within the Bitcoin community. The notion of utilizing opcode contexts in such a manner could open new avenues for script innovation and optimization, marking a significant step forward in the evolution of Bitcoin scripting capabilities.
