Subject: Re: [bitcoin-dev] Is there a tool like Ethereum EVM at present for
 Bitcoin script?
Precedence: list

thanks for you suggestion, Gijs.

I spent some time learning miniscript, and there are some problems that =
need to confirm for me:

1. Is miniscript a brand new Bitcoin scripting language?
2. If I use miniscript, do I need to compile it into a Bitcoin OP_CODE =
script? If so, how to do that ? has someone written a compiler?=20
I found that @sipa has open sourced a compiler implemented in C++ on =
github( https://github.com/sipa/miniscript ). This should translate the =
policy language into miniscript;

[Miniscript][1], [Min.sc][2], [Simplicity][3] and [Sapio][4]. These are =
all higher level languages that compile to Bitcoin Script. Sapio is =
"just" Rust, so that might fit your setting best.
