Added
- Replace GMP's primality test function with our own based on Baillie-PSW. The new primality test is based on the 2020 paper "Strengthening the Baillie-PSW primality test" by Robert Baillie, Andrew Fiori, Samuel S. Wagstaff Jr. The new test works approximately 20% faster than GMP library's mpz_probab_prime_p() function when generating random 1024-bit primes.
Changed
- Refactor form exponentiation, start from top bits of exponent. This slightly improves performance of VDF proof verification.
Fixed
- We've moved to pybind 2.6.2 to avoid a possible shutdown bug in Python 3.9.0.
