Miniscript is a new movement in the world of programming. Started by Pieter Wuille, Andrew Poelstra, Sanket Sanjalkar, Miniscript offers a tree-based representation of the Bitcoin scripting language.
Here is what it means: coding will be easier, efficient, and complex conditions can be met.
As per the email sent by Pieter to the Bitcoin developers, Miniscript will help you write “scripts in a structured way, enabling analysis, composition, generic signing, and more.”
Here is an example:
With Miniscript, the code is human-readable and can be used in multi-signature wallets, construction of atomic swaps, and the Lightning network.
For every Bitcoin transaction, there is a code attached. This code is known as the Bitcoin Script (or Bitcoin Scripting Language). As it comes with limited functionality, Miniscript is adding value to see the kind of sophisticated conditions that can be created and implemented.
With the various of examples out there to help you build programs for Bitcoin, we believe Miniscript will act as a powerful catalyst and boost the current pace of development.
Note: Miniscript is still work in progress. As mentioned in the email:
Miniscript is designed for Bitcoin as it exists today (primarily P2WSH), and does not need any consensus changes. That said, we plan to extend the design to support future script changes Bitcoin may include.
