Lets say Alice wants to send funds to Bob, but wants to use a mixer.
Mixers are centralized, trusted bots that take an input transaction from Alice and sends it to Bob, but pools the funds in such a way the transaction cannot be traced back from Bob to Alice.
Here's how it would word:
Alice, Bob, and Charlie all set up their accounts using camo, so their rep is set to their ECDH public key.
Alice creates a new camo seed: Annie. She sends the funds meant for Bob to Annie.
Alice then uses Annie to send the funds to Charlie.
