A 'decryption' key is not a 'viewkey'.  Hmmm, then why have a viewkey in Cryptonote if the recipient also has a decryption key? Because in Cryptonote the private decryption key would also enable one to spend the coins. The decryption key in Zcash has other properties, but it is not necessarily consistent with what everyone else here is referring to when they say 'viewkey'.

CoinHoarder I don't know why you bother to try to write that long diatribe to further show everyone how you are all about ego and character assassination, instead of teamwork and production. Wasting time. And you should be studying since you claimed you have a full load this semester (and I should be coding), so you are wasting your time and my time with nonsense (as usual).
