Hey everyone! I'm excited to announce I've built a simulator for Ethereum on RISC-V that I've been making compatible with Arbitrum Stylus. I've just posted a post on a part of the experience developing it, which you can read below. To recap what RISC-V and Stylus is:

RISC-V is an open source "reduced instruction set" instruction set. There's been some discussion of switching Ethereum off the EVM to RISC-V, for the gains in ZK proving. RISC-V is normally used in an embedded context, though several teams are trying to ZK prove its execution (Risc Zero).

Stylus is totally awesome. At @superpositionso we're huge users of it for our prediction market @9livesso and more! We want to see Stylus be the programming language for all smart contract development in the future, and we want to build derivative technologies using RISC-V too.

Arbitrum Stylus is a Rust smart contract programming SDK. With Stylus, you can write smart contracts in any programming language for much cheaper, because the Arbitrum nodes run your WASM code alongside the existing EVM! You can call EVM contracts and vice versa without any in between.
