Advanced cryptography. OTOH:
* Each transaction is signed by a "ring signature", where it's known that 1 of a set of 8 keys signed the transaction, but not which one. This is your actual input plus 7 other random inputs drawn from the same probability distribution as actual inputs.
* Double-spending is prevented by a "key image" which is something mathematically related to your actual key (not sure how that's verified without knowing which key it is). Each key image can only be used once, or it's a double-spend.
* Input amounts and output amounts have to balance using some kind of zero-knowledge proof.
