  3. 3. Ordinary CryptoNote Technology Let’s compare! 3 Alice wants to send a coin to and keep this transfer private.Romulus To achieve this, she uses Bob’s and Carol’s coins as *mixins. At the same time, Dave wants to send a coin to , and also wants toRemus keep the transfer private. To achieve this he took Bob’s coin as a *mixin. *mixin - it's a part of Cryptonote technology that makes your transfer private. coin coin coin coin coin coin Alice Romulus: “From Alice, Bob or Carol?” Remus: “From Bob or Dave?” Bob Carol Dave Ordinary CryptoNote transfer Boolberry Solves CryptoNote Issues

  9. 9. How does solve this critical issue? Modified CryptoNote Technology Unlike other CryptoNote coins such as Bytecoin and Monero, Boolberry has a special in each transaction’s output.flag With that flag the sender can set the output to be used only with specified number of mixins. In other words, this flag guarantees that this coin won’t be spent without mixins, so it will never compromise ring signatures in which it was involved. 9 Ordinary CryptoNote Technology Boolberry Solves CryptoNote Issues
