In bitcoin, every transaction in the shared ledger has the sender, recipient, and value. This ledger gets appended infinitely and is shared within a peer-to-peer network. Zcash is a cryptocurrency with all the features of bitcoin, plus encrypted transactions. The sender, recipient, and value fields are all encrypted.
If bitcoin is HTTP, Zcash is like HTTPS, a secure transport layer. Nathan Wilcox works on Zcash, and in this episode we discuss why an encrypted version of bitcoin is useful, how mining works, and how Zcash the company is structured. Nathan also gives some context for the current state of the bitcoin community, and where Zcash fits in.
