The "No Taproot" section of the Sapio docs need updating :) What are
your plans to take advantage of Taproot with Sapio? It would have been
interesting to see what a Taproot emulator would have looked like,
although no need for it now. It seems to me Taproot would have been
harder to emulate than CTV though I could be wrong.

https://learn.sapio-lang.org/ch05-02-taproot.html

Also there have been a number of people asking questions about Sapio
and CTV on the Libera equivalents of Freenode channels #sapio and
##ctv-bip-review over the past months. Do you plan to join and claim
those channels?

This has actually never been true (Sapio assumes extensions).

If the extensions are not present, you can stub them out with a signing
federation instead, configurable as flags, and you can also write many
contracts that do not use the ctv based components at all.

The protocol for emulation is a bit clever (if I do say so myself) since it
ensures that contract compilation is completely offline and the oracles are
completely stateless.

Will update those soon / in November. Sapio needs the rust Bitcoin taproot
ecosystem to mature, as well as a spec for miniscript taproot (altho we can
kinda monkey patch one in without it).

To be honest, I had some technical difficulties with getting Libera to work
and I gave up... But perhaps I can retry getting it to work again. Irc
infra 🤷‍♂️ struggles...

It is worth checking out Ivy lang Playground by Dan Robinson, but AFAIK, it's not actively maintained. It compiles contracts to Bitcoin Script: https://www.ivylang.org/bitcoin

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

[Null Null]

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? 
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;

[Andrew Poelstra]

Simplicity does not compile to Bitcoin Script, and Sapio assumes extensions
to Bitcoin Script that are not currently part of the consensus code.

Hi,


Bitcoin does not have a virtual machine. But you do have [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.

By the way, this question also has an answer on [Bitcoin Stackexchange][5]
which is a great resource for questions like this.

[bitcoin-dev] Is there a tool like Ethereum EVM at present for Bitcoin script?

[Null Null]

Hi all,

Is there a tool like Ethereum EVM at present? Users can write bitcoin scripts in a syntax just like python(or like other programming language); through this tool, they can be translated into bitcoin original scripts; it sounds like a new programming language has been invented.

In my opinion， Bitcoin script programming is based on reverse Polish expression; this is not friendly to programmers;

In fact, Bitcoin's opcode expression ability is very rich, and it may be unfriendly, which has affected the promotion of Bitcoin in the technical community.

Hope for hearing some voice about this.

Best wish.
