Key Points

• In general, binaries built just for x86 architecture will automatically be run in x86 mode
• You can force apps in Rosetta 2 / x86 mode by right-clicking app, click Get Info, check "Open using Rosetta"
• You can force command-line apps by prefixing with arch -x86_64, for example arch -x86_64 go
• Running a shell in this mode means you don't have to prefix commands: arch -x86_64 zsh then go or whatever
• Don't just immediately install Homebrew as usual. It should most likely be installed in x86 mode.

Homebrew

Not all toolchains and libraries properly support M1 arm64 chips just yet. Although

Suppose we wish to model a UTXO system on the EVM. We need to represent UTXO tokens such that all value is preserved when tokens are spent. Note: For this example, we are not concerned about the security of the system and are satisfied with giving authorities the power to create tokens (e.g. as in a plasma system).

Consider the following object:

{
  owner: <address>,
  value: <uint>,
