Re-introducing EVM Diff

EVM Diff is the easiest way to diff EVM-compatible chains in a friendly format, now with automated discovery of chain differences, making it much more scalable.

There's two ways to diff:
- Two chains side-by-side
- All chain in a caniuse.com-like table

Security at Optimism. Formerly built Umbra and more at ScopeLift

It would be great that in addition to supported opcodes, we get the cost of each one. In ZkSync for example, there are multiple differences. 
Good work ✅

It's hard to get entirely accurate because opcode gas pricing gets complex since they are a function of things like cold/warm slots and memory usage. Some more info on the plans in https://github.com/mds1/evm-diff/issues/67 and

Definitely true. To bypass the complexity, might be interesting to define something like the « minimal cost » which will represent the least gas units an opcode can consume knowing his stack/memory/storage inputs.
