Zerocash protocol

On 16 November 2013, Matthew D. Green announced the Zerocash protocol, an extension to Zerocoin to provide additional anonymity by shielding the amount in a cryptocurrency transaction.^[1]

Zerocash reduces transaction sizes by 98% over Zerocoin, however is significantly more computationally expensive, taking up to 3.2GB of memory to generate.^[2]^[3] More recent developments into the protocol have reduced this to 40MB.^[4]
