The decodescript RPC decodes a hex-encoded script into readable information, detailing its type, any related addresses, and its assembly language form.

How is this used?

You've discovered an ancient scroll with instructions written in a mysterious, coded language. This scroll holds the secrets to unlocking a treasure, but only if you can understand its instructions. In the Bitcoin world, scripts are like these instructions, guiding how transactions are processed and secured. However, they're often written in a compact, hex-encoded format that's not easy to read. The 'decodescript' command is like the key to translating these encrypted instructions into a language you can understand, revealing the script's purpose, structure, and operational details.
