"Bytecoin is the first cryptocurrency created with CryptoNote technology and is not a Bitcoin fork. Bytecoin allows users to make absolutely anonymous money transfers through the CryptoNote algorithm. CryptoNote implements the ring signature technology which allows you to sign a message on behalf of a group. The signature only proves the message was created by someone from the group, but all the possible signers are indistinguishable from each other."

Even if outgoing transactions are untraceable, everyone may still be able to see the payments received and thus determine one's income. By using a variation of the Diffie-Hellman exchange protocol, a receiver has multiple unique one-time addresses derived from his single public key. After funds are sent to these addresses they can only be redeemed by the receiver; and it would be impossible to cross-link these payments.
Bytecoin is CPU-minable and ASIC resistant. Difficulty and max block size readjust automatically based on the system's previous state. Genesis Date July 04, 2012 (over 5 years)
