Zerocoin is a proposed extension on Bitcoin to make Bitcoin more private. Zerocoin only hides the origin of a payment, the destination and amounts are still public.
Zerocash is a further extension of the zerocoin protocol which hides the destination and amounts. Zerocash transactions are more compact than zerocoin transactions.
Zcash is an implementation of the zerocash protocol onto a new altcoin. Both Zerocoin and Zerocash were intended for extensions to Bitcoin (they would require a fork). However zcash is just an altcoin (it began as a software fork of Bitcoin) with the zerocash protocol on top.
Thank you. Do you mean
ZcashandBitcoinuse the same blockchain? (Since Zcash is an independent coin); Thanks – Questioner – 2018-09-12T13:42:43.8502No, they use separate blockchains. Zcash is an altcoin which implements the Zerocash protocol. – Andrew Chow – 2018-09-12T13:44:05.413
A bit off-topic: for anonymity features of ZCash, see also https://crypto.stackexchange.com/a/64281/36884
