Generate Bulletproofs(+) generators at compile time Creates a new monero-generators crate so the monero crate can run the code in question at build time. Saves several seconds from running the tests. Closes https://github.com/serai-dex/serai/issues/101. 2022-08-21 10:36:53 +00:00			`use curve25519_dalek::edwards::EdwardsPoint;`
Implement hash_to_point in Rust Closes https://github.com/serai-dex/serai/issues/32. 2022-07-10 20:11:55 +00:00

Implement Bulletproofs in Rust (#69) * Initial attempt at Bulletproofs I don't know why this doesn't work. The generators and hash_cache lines up without issue. AFAICT, the inner product proof is valid as well, as are all included formulas. * Add yinvpow asserts * Clean code * Correct bad imports * Fix the definition of TWO_N Bulletproofs work now :D * Tidy up a bit * fmt + clippy * Compile a variety of XMR dependencies with optimizations, even under dev The Rust bulletproof implementation is 8% slower than C right now, under release. This is acceptable, even if suboptimal. Under debug, they take a quarter of a second to two seconds though, depending on the amount of outputs, which justifies this move. * Remove unnecessary deref in BPs 2022-07-26 07:05:15 +00:00
Initial documentation for the Monero libraries (#122) * Document all features * Largely document the Monero libraries Relevant to https://github.com/serai-dex/serai/issues/103 and likely sufficient to get this removed from https://github.com/serai-dex/serai/issues/102. 2022-09-28 12:44:49 +00:00			/// Monero's hash to point function, as named `ge_fromfe_frombytes_vartime`.
