Ring signatures are a ring of possible signers to a transaction where only one of the signers is the actual sender. This helps obfuscate the true history of transaction outputs. Loki uses a fixed ring size of 10, meaning there are 10 possible outputs, including the true output. 

Ring Signatures

Stealth addresses ensure that the true public key of the receiver is never linked to their transaction. When a Loki transaction is sent, a one time stealth address is created, and funds are sent to this address. The receiver is able to calculate a private spend key and take ownership of the funds without revealing their own address.

Stealth Addresses

RingCT uses range proofs to prove the amount of a transaction is between 0 and 2^64, ensuring only non negative amounts of currency are sent, without revealing the actual amount sent.

Loki bases its code off of Monero due to the high level of privacy it is able to provide. Monera is an evolution of the CryptoNote protocol, which uses ring signatures, stealth addresses, and RingCT to give users the ability to sign transactions and obfuscate amounts while maintaining deniability.
