Zcoin (XZC) Information{coin_name} ({symbol}) Information

Zcoin, a decentralized and open source currency that provides financial privacy enabled by the Zerocoin protocol. Proven cryptography and auditability.

Questions and AnswersQuestions and Answers

What are the differences between Zcoin and Zcash?
A common misconception is that Zcoin is a fork of Zcash. Zcoin is based off the Zerocoin paper while Zcash is based off the Zerocash paper. While the Zerocoin paper and Zerocash paper share common authors and both use zero knowledge proofs, they rely on different cryptography. There is otherwise no relation between the two projects.
As a truly anonymous cryptocurrency, won’t Zcoin be used for terrible things?
As with any other technology, Zcoin can be used for both good and evil. However, we are firm believers that the net good for Zcoin far outweighs the bad. Throughout history, freedom of commerce has been shown to prevent wars, promote prosperity, and increase cross-culture exchange. Zcoin is designed to benefit legitimate users who have realized the risk of using a cryptocurrency with a completely transparent public ledger, and the danger of having all their financial details made public with Bitcoin. Because there are already pre-existing mechanisms for such activities, Zcoin does not affect the status quo for such activities, while it provides notable benefits to legitimate users. Even without Zcoin, such transactions can take place via existing financial systems (e.g. by using cash. Although not actually private, Bitcoin has faced the scrutiny of regulators with its potential use in money laundering.
Why create a new coin, when we already have Bitcoin?
The Zerocoin Protocol, created in 2013, was originally meant to be an extension on top of Bitcoin. There was a lot of support for Zerocoin from key members of the Bitcoin community. However, Bitcoin has the primary goal of ensuring stability in its money supply, by moving slowly with only unanimously agreed upon changes. As a result of the political deadlock, the Zcoin project was created.
What is Zcoin’s mission?
Zcoin strives to increase individual liberty. By guaranteeing financial privacy, Zcoin can help ensure freedom of commerce. People should be able to transact however they want, as long as it does not infringe on the well-being or individual liberty of others. We are also big believers that freedom of commerce also facilitates peace and prosperity across countries and cultures. By guaranteeing financial privacy, Zcoin can directly guarantee fungibility, an essential property for free commerce. Although there are many anonymity solutions out there for cryptocurrencies, it is our aim in providing the strongest level of anonymity that is possible without sacrificing usability, the auditability of our coin supply and relying on well established cryptographic protocols.
What will Zcoin’s Founders Reward be used for?
The Founders Reward is to reward the funding given by early investors, the time invested by the developers and a bounty wallet used to fund the team and other Zcoin community efforts. Bounties are available for various tasks, such as Zcoin core development, web development, graphic design, marketing, etc. If you’d like to help out, please email or message us on Discord.
What is the total supply and distribution for Zcoin?
There will be 21.4 million Zcoins. Zcoin follows the same halving cycle as Bitcoin (every 4 years). It was originally planned that 20% of Zcoins (10 XZC per block) in the first 4 years will be distributed to the Founders’ Reward which is equivalent to 10% of total supply. The Founders’ Reward consists of Poramin Insom (lead dev and Founder) (4%), seed investors (12%) and the team wallet (4%). However upon the launch of Znodes, the Founders and the team have agreed to reduce this to 14% of the block reward: 2% Poramin Insom, seed investors (6%) and team wallet (6%). To find out how the Founder’s Rewards are used, see here. After the first 4 years, the block reward goes completely towards the miners and Znode rewards.
What is MTP?
The MTP (Merkle Tree Proof) algorithm was devised by Alex Biryukov and Dmitry Khovratovich from the University of Luxembourg in their paper published on the 11 June 2016 titled Egalitarian Computing. These are the same researchers who came up with Equihash that is currently used in ZCash and the Argon2 key derivation function. MTP promotes fair and democratic mining by making ASIC development expensive. The key element of this approach is large (in size) and intensive (in bandwidth) use of RAM. RAM is expensive in both FPGA and ASIC and slow on GPU. Previous attempts in large and memory intensive proof of works were problematic. This is because to verify these memory intensive proof of works, the nodes had to also have that memory and spend a relatively long time calculating it. This made the network susceptible to transaction DoS attacks where nodes are constantly occupied in verifying transactions. MTP’s advancement means that hard memory intensive proof of works can be verified quickly with low resources. MTP was designed to be able to require miners to utilize large amounts of RAM up to potentially 10 gb while remaining fast to verify! This can potentially revolutionize PoW mining by bringing it closer to the original vision of Satoshi where one CPU = one vote and democratizing mining instead of keeping it within a handful of powerful miners while maintaining a resilient and low resource network of nodes.
What mining algorithm does Zcoin use?
Zcoin uses a temporary algorithm Lyra2z It is a chained algorithm with Blake256 first round and Lyra2 (timecost = 8, r=c=8) for the final round. It was designed to achieve a slight advantage to GPU while making it feasible for CPU mining. This algorithm will be replaced by MTP which aims for democratic mining without sacrificing performance. To read more on the MTP mining algorithm, click here. MTP is currently running our testnet and is expected to go live in September 2018.
How does Zcoin compare to other cryptocurrencies with anonymizing properties?
Bitcoin and preceding alternative cryptocurrencies have attempted to solve this problem through the use of transaction mixers or ring signatures. But they score very poorly on the metric called the traceability set. The traceability set is a key metric to understanding how private a cryptocurrency is. The traceability set in formerly proposed solutions is limited by the size of the mixing cycle or ring signature. Each mixing cycle or ring signature is limited by the number of transactions per cycle, which is transitively limited by the the block size of the cryptocurrency. Thus, the traceability set in previous attempts at privacy tends to only be a few hundred. With Zcoin, the traceability set is on a dramatically higher magnitude. Instead of having a traceability set limited to the few hundreds, Zcoin has a traceability set that encompasses all minted coins in an accumulator. Thus, the magnitude of the traceability could be in the order of many thousands rather than hundreds. So its privacy level is magnitudes higher than cryptocurrencies that rely on mixing or ring signatures. The other problem is that tumbling methods are only secure under the assumption of a lack of topological analysis and pre-existing network data, which is an incorrect threat model. There have been multiple research papers demonstrating that taking a separate network topology like Facebook can be used to de-anonymize a cryptocurrency as long as a long chain of transaction history exists. With all previous cryptocurrencies, a long chain of transactions is publicly viewable on the blockchain and prone to topological analysis. With Zcoin, this long chain of transaction history simply does not exist, and there is zero information leakage about the sender and receiver of a transaction, so it is not prone to topological analysis and so the link between the sender and receiver disappears.
What parameters does Zcoin use for its setup?
Zcoin uses the RSA-2048 number from the RSA factoring challenge. The computer’s hard drive which generated the factors were destroyed over 25 years ago. No factoring solution to the RSA-2048 number has been found for the past 25 years, and it is unlikely to be factored in the next several decades. In the long term, Zcoin would eventually shift to a different cryptographic scheme for its setup parameters or move to a trustless setup entirely.
