Bytecoin is the first type of cryptocurrency which ensures that secure CryptoNote protocol can be used for the security of users. It provides 100% untraceable transactions with the help of ring signatures and stealth addresses. However, the algorithm of Bytecon which is known as CryptoNight was created by BCN developers in collaboration with CryptoNote team. It was designed to make GPU and CPU mining equally effective and limit ASIC mining. Its roadmap includes colored coins and assets. It was introduced back in 2012 and it has been forked more than 25 times. However, it still remains the most successful CryptoNight since its inception in terms of market cap.
