With the new Zerocash protocol, unlike the old Zerocoin protocol, users can make direct payments to each other with a vastly more efficient cryptographic protocol that also hides the amount of the payment, not just its origin.
With the new Zerocash protocol, Zerocoin allows direct anonymous payments between parties. Zerocoin transactions exist alongside the non-anonymous Bitcoin currency. Each user can convert non-anonymous bitcoins into anonymous coins, which we call zerocoins.
Users can then send zerocoins to other users, and split or merge zerocoins they own in any way that preserves the total value. Users can also convert zerocoins back into bitcoins, though in principle this is not necessary: For a more detailed explanation of the new Zerocash protocol see the website for Zerocash protocol. The plan is to make an altcoin, powered by the new Zerocash Protocol, that provides consumers with the financial privacy they expect from debit cards, credit cards, and cash.
To do this, we plan on release a working, non research code quality client based off the bitcoin 0. Created by Ian Miers imichaelmiers.
It is now not an extension to the bitcoin, but rather an independent technology with the same basic principles as blockchain and transactions, which was planned to implement in alt-coin.
Between 5 October and 11 January , the Zerocash website started noting that "The Zerocash protocol is being developed into a full-fledged digital currency, Zcash. One criticism of zerocoin is the added computation time required by the process, which would need to have been performed primarily by bitcoin miners. If the proofs were posted to the blockchain, this would also dramatically increase the size of the blockchain.
Nevertheless, as stated by the original author, the proofs could be stored outside of the blockchain. Since a zerocoin will have the same denomination as the bitcoin used to mint the zerocoin, anonymity would be compromised if no other zerocoins or few zerocoins with the same denomination are currently minted but unspent.
A potential solution to this problem would be to only allow zerocoins of specific set denominations, however, this would increase the needed computation time since multiple zerocoins could be needed for one transaction.
Since n has to be hard to factor, p and q must be unknown to normal users for zerocoin to be secure. The protocol could rely on RSA unfactorable objects to avoid having to have a trusted party for the setup process. Zerocoin team anounced that a single-symbol error in a piece of code "allowed an attacker to create Zerocoin spend transactions without a corresponding mint".
