Questions tagged [zk-snarks]

At the moment ring signatures are more eficient than zk-SNARKS, but as fluffypony already comment, probably any cryptocurrencie in the future will use this technology. Can monero implement zk-SNARKS in the future if needed? How can it be done?

I have read that Zcash is a "trusted" system and that Monero is "trustless". As they are both open source projects, what is the difference. What makes Monero "trustless"?
