EIP 5843: EVM Modular Arithmetic Extensions

This is a proposal to add EVM opcodes for efficient modular addition/subtraction/multiplication in cases where the modulus is odd, 1-1024 bits and fixed for many operations. It is an iteration from previous work on EVM384. It makes use of the following observations to construct a more efficient model for modular arithmetic operations in the EVM: If the modulus is odd and fixed for multiple operations and we also precompute some values using it, caching these and the modulus in ephemeral ca…
