ATMOS is a marker on the EOS block chain. It provides substitution and anonymity through the use of a delinked token system (side chain) of secret addresses, ring signatures and secret transactions. ATMOS is placed on the main chain of EOS to participate in the verification of side chains. The authenticator approves that any standard EOS token (including the EOS itself) can go out of the side chain. The verifier charges a fee to the system, such as when the token moves from the main chain to the side chain and returns.
