Weikeng Chen[@weikengchen](https://twitter.com/@weikengchen)has implemented arithmetic operation Bitcoin scripts based on the Mersenne prime M31 field. Future plans include expanding it to the Goldilocks field. Both M31 and BabyBear fields require a degree 4 extension, while Goldilocks64 only requires a degree 2 extension. Due to the inability of Bitcoin operation opcodes to handle signed 32-bit overflow issues, Goldilocks64 needs to be represented by three u32 numbers to avoid overflow and related problems. github link:<https://github.com/BitVM/rust-bitcoin-m31-or-babybear>
