Boog900 89eef95fb3 Monero: support for legacy transactions (#308 ) * add mlsag * fix last commit * fix miner v1 txs * fix non-miner v1 txs * add borromean + fix mlsag * add block hash calculations * fix for the jokester that added unreduced scalars to the borromean signature of 2368d846e671bf79a1f84c6d3af9f0bfe296f043f50cf17ae5e485384a53707b * Add Borromean range proof verifying functionality * Add MLSAG verifying functionality * fmt & clippy :) * update MLSAG, ss2_elements will always be 2 * Add MgSig proving * Tidy block.rs * Tidy Borromean, fix bugs in last commit, replace todo! with unreachable! * Mark legacy EcdhInfo amount decryption as experimental * Correct comments * Write a new impl of the merkle algorithm This one tries to be understandable. * Only pull in things only needed for experimental when experimental * Stop caching the Monero block hash now in processor that we have Block::hash * Corrections for recent processor commit * Use a clearer algorithm for the merkle Should also be more efficient due to not shifting as often. * Tidy Mlsag * Remove verify_rct_* from Mlsag Both methods were ports from Monero, overtly specific without clear documentation. They need to be added back in, with documentation, or included in a node which provides the necessary further context for them to be naturally understandable. * Move mlsag/mod.rs to mlsag.rs This should only be a folder if it has multiple files. * Replace EcdhInfo terminology The ECDH encrypted the amount, yet this struct contained the encrypted amount, not some ECDH. Also corrects the types on the original EcdhInfo struct. * Correct handling of commitment masks when scanning * Route read_array through read_raw_vec * Misc lint * Make a proper RctType enum No longer caches RctType in the RctSignatures as well. * Replace Vec<Bulletproofs> with Bulletproofs Monero uses aggregated range proofs, so there's only ever one Bulletproof. This is enforced with a consensus rule as well, making this safe. As for why Monero uses a vec, it's probably due to the lack of variadic typing used. Its effectively an Option for them, yet we don't need an Option since we do have variadic typing (enums). * Add necessary checks to Eventuality re: supported protocols * Fix for block 202612 and fix merkel root calculations * MLSAG (de)serialisation fix ss_2_elements will not always be 2 as rct type 1 transactions are not enforced to have one input * Revert "MLSAG (de)serialisation fix" This reverts commit `5e710e0c96`. here it checks number of MGs == number of inputs: `0a1eaf26f9/src/cryptonote_core/tx_verification_utils.cpp (L60-59)` and here it checks for RctTypeFull number of MGs == 1: `0a1eaf26f9/src/ringct/rctSigs.cpp (L1325)` so number of inputs == 1 so ss_2_elements == 2 * update `MlsagAggregate` comment * cargo update Resolves a yanked crate * Move location of serai-client in Cargo.toml --------- Co-authored-by: Luke Parker <lukeparker5132@gmail.com>		2023-07-04 17:18:05 -04:00

Monero Generators

Generators used by Monero in both its Pedersen commitments and Bulletproofs(+). An implementation of Monero's ge_fromfe_frombytes_vartime, simply called hash_to_point here, is included, as needed to generate generators.

This library is usable under no_std when the alloc feature is enabled.
