This is a joke right? Shadowcash was deanonymized by xmr dev in one day because sdc devs don't know first thing about how ring signatures work. Tor is also poor privacy network, which is why xmr is including i2p integration instead. zeroknowledge proofs are a bad thing in crypto because they are a trusted-setup technical failure. "SPEC is the most private and anonymous cryptocurrency network today." - this is quite a statement with zero technical reasoning.
