This is an Harmony transaction mixer that ultilizes parts of CryptoNote to enable zero-knowledge transactions. Ported from Heiswap from Ethureum.
It ulitilizes Ring Signatures and pseudo-stealth addresses to achieve its zero-knowledge properties. Ring signatures was only possible on the EVM (gas-wise) due to the recent addition of EIP198 and EIP1895.
