Tutorial title

Running MIPS programs on the EVM

Tutorial description

Running a VM for a normal CPU. such as MIPS, lets us run a general-purpose VM on top of the EVM. This will allow us to compile programs written in standard computer languages like Go and Rust and execute them on-chain.

• Why do this?
  • Simplify on-chain programming
  • Background, optimistic rollups vs. trusting rollups.
  • The current state of the art
• Running MIPS on-chain
  • The Optimism code (https://github.com/ethereum-optimism/optimism/tree/develop/packages/contracts-bedrock/src/cannon/libraries)
  • Creating a MIPS VM library/smart contract
  • "Hello, world" - trivial MIPS assembler program
• Compile a program (Go? Rust? I'm not sure yet) and run it on the MIPS on top of the EVM.
• Dealing with library functions and system calls
• Conclusion
  • Solidity is probably better in most cases
  • This can be useful for extremely cheap networks, such as Redstone.

Sorry to nag @wackerow , but I'd love to start working on this. Is this interesting? It will be a gas hog, but at today's L2 prices that's not such a huge problem.

@qbzzt Hey! Thanks for the ping. Agree that it seems like a gas hog but we currently have a surplus. Let's go for it!
