Zcoin has “Znodes” coming out in a week. That is why you see the price increase.

Zcoin is the first full implementation of the Zerocoin Protocol, which allows users to have complete privacy via Zero-Knowledge cryptographic proofs. It is worth noting that Zcoin is unrelated to other cryptocurrencies utilizing the Zerocash Protocol. Although Zerocash is a development from Zerocoin, their respective implementations are not simple forks of each other, but rely on different cryptographic assumptions with various tradeoffs. Both approaches supplement each other quite nicely, and a good way to describe them would be sibling projects.

The Zerocoin Protocol is being actively researched and improved, such as by a new that when implemented would hide transactions and address balances. With Zcoin’s Zerocoin Technology, you can “mint” a coin found on the public ledger into a private coin. When it is time to spend your minted coin, the owner of the minted coin does not need to be revealed. The process of minting and spending a coin can be completed as many times as you want, ensuring complete privacy. Notable studies have shown that the same techniques used to analyze social network topology can be used to analyze Bitcoin’s network topology. Anyone can use the public ledger to break privacy, including powerful corporations and institutions such as the NSA. 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. Cryptographic Implementations Zcoin uses RSA accumulators which were introduced in 1993 as the foundation of our anonymity scheme while Zcash uses zk-SNARKs which was recently formulated in 2014 and very few ppl understand it. Comparatively, RSA cryptography is one of the earliest form of public key cryptography which was publicly described in 1977, has been battle tested and forms the basis of many encryption schemes in wide use today such as HTTPS, SSH logins and PGP for e-mail.

It also uses the Fiat-Shamir transform scheme that was published in 1986. Peter Todd’s blog illustrates this perfectly in pointing out that if RSA breaks, Zcoin would probably be the least of your concerns. Zk-SNARKs as used in Zcash requires on more novel which have not been really been put under serious scrutiny. It is a serious enough problem that the which remain in research stage and are currently impractical to use. If these cryptographic assumptions do not hold, then the cryptography in Zcash breaks.

This combined with an unauditable supply that may make it impossible to detect such problems means that zk-SNARKs although technologically advanced, is taking certain risks to achieve it. Trusted Setup While both Zcoin and Zcash uses, they are implemented differently. Zcoin’s setup is conceptually very simple as it only involves taking two primes p and q, to generate a modulus n.

P and q are then destroyed. Instead of generating these parameters ourselves, we use parameters that were generated from the RSA factoring challenge many years ago so there is no possibility that the devs of Zcoin know these parameters. In fact, successfully obtaining those parameters would have netted you a nice bounty from the RSA (before they discontinued the challenge)! You can read more on how these parameters were generated and destroyed. Our opinion is that the simpler the setup process, the less things can go wrong. However are now positive that we can remove trusted setup completely using the that would allow us to continue using the high anonymity of zero knowledge proofs without worrying about trusted setup and this is currently in development. Zcash’s setup is more elaborate and involved 6 trusted people, and can be read.

But in short, all six participants need to collude or be compromised for the parameters to be leaked out. Auditable Supply The main risk of having trusted setups being broken is that an attacker can counterfeit coins out of thin air. Zcoin features a fully auditable coin supply. In our view, this is immensely important as in the event of any issues with our trusted setup or cryptographic implementation, this can be detected.

No code is ever perfect even with the best of audits and new threats and vulnerabilities are constantly being found. For example, even being generated and an auditable supply allows such bugs to be found and fixed. With Zcash’s use of private transactions and addresses where amounts are also hidden, it is very difficult to detect if a vulnerability is exploited or a problem in their trusted setup. It is to be noted that Zcash’s own audit itself and despite it being fixed, it is noted that in their own post that: “Building secure crypto protocols is hard, and even our team of world-class cryptographers and security engineers will make mistakes along the way. Despite the challenge, we’re optimistic that our practices of careful security review and transparency will lead to a secure product. At this point the Zcash protocol has been subjected to intense security review, first through scientific peer review, and then by our in-house team of experts. But we need even more scrutiny to gain assurance that the protocol is safe.” We applaud Zcash’s developments and highly value their work in the cryptocurrency space and look forward to seeing their advances.

However, we feel Zcoin has a place in providing one of the best anonymity systems which is built on proven cryptography and is setup in such a way that flaws if exploited, can be detected. Poramin Insom.

Zcoin, also known as XZC or Zerocoin, is a cryptocurrency that aims to facilitate private financial transactions. Dash DASH Mining Today. Find out how it works today in our Zcoin review. What Is Zcoin?

Zcoin is an implementation of the ZeroCoin Protocol, designed to be the world’s most. One of the key innovations of the ZeroCoin Protocol is its use of Zero Knowledge Proofs, which guarantee complete financial privacy anonymity. Many people believe bitcoin is an anonymous digital currency. However, bitcoin is one of the least private digital currencies available online today. The transactions are broadcasted on a public ledger. Anyone can see your bitcoin address, your, and the value of your wallet. All it takes is one connection between your bitcoin address and your personal information, and anyone can use the public ledger to spy on your funds.

That’s where Zcoin, released in October 2016, sees an opportunity for improvement. Zcoin improves the privacy of bitcoin’s protocol. With that in mind, let’s take a closer look at how Zcoin works. How Does Zcoin Work? Zcoin improves the privacy of bitcoin’s protocol in the following core ways: Minting: Zcoin uses ZeroCoin technology that allows users to “mint” a coin found on the public ledger into a private coin.

Spending: When you need to spend your minted coin, you don’t need to reveal your identity. The owner of a minted Zcoin does not need to be revealed to complete a transaction. Repeat: The process of minting and spending a coin can be completed as many times as you want, ensuring complete privacy. The foundation of Zcoin relies on Zero Knowledge Proofs. Zero Knowledge Proof is a method in which a person can prove to another person that a given statement is true without conveying any information apart from the fact that the statement is true.

Obviously, that sounds contradictory. However, the ZeroCoin Protocol is based on this concept. Basically, Zcoin uses zero knowledge proofs by making a zero knowledge cryptographic statement. When someone receives a Zerocoin digital token, that person only knows that “X” amount of money was sent to their wallet. There’s no other information attached to the transaction. So unlike bitcoin, there’s no wallet address or other information exchanged between the sender and receiver, or even any attached transaction history.

With Zerocoin, transactional history is completely removed. Another key technological feature behind Zcoin is the Merkle Tree Proof of Work (MTP). MTP is a mining algorithm that emphasizes high performance, high security, and egalitarian computing. MTP was introduced in 2016 to create a more privacy-centric cryptocurrency ecosystem. Some of the benefits of MTP include a reduced ability for botnets to mine, and an increased ability for legitimate CPUs to perform proof of work.

You know how the bitcoin community is frequently accused of being run by a few major mining pools? MTP is often proposed as a way to deal with that problem. It allows a memory hard proof of work to be used while remaining very lightweight and quick for nodes and miners to verify.

Zcoin was the first cryptocurrency to implement MTP, something they achieved in 2017. Zerocoin also uses features like Znodes (incentivized nodes for Zerocoin processing) and the Sigma Protocol (which allows for trustless setup).

The developers expect to develop Sigma Protocol over 2017, although it could be pushed in 2018. By 2018, they also hope to create a decentralized marketplace where users can trade items or Zcoin without the need for a centralized marketplace or exchange. About Zcoin Tokens There will be a total supply of 21 million Zcoins. The tokens will follow the same halving cycle as bitcoin (every 4 years), with 10% of the total Zcoin supply being distributed to the Founders Reward as time passes. The Founders Reward is given to early investors, developers, and Zcoin community members.

It’s important to note that Zcoin is not a fork of Zcash. ZeroCoin is the technology, and Zcoin is the coin – similar to how Zerocash is the technology and Zcash is the coin. There is, however, a connection between the two currencies: Zerocash was built on Zerocoin’s concept, although it wasn’t a fork of the Zerocoin blockchain. Zerocash was built to address the perceived shortcomings in Zerocoin. Who’s Behind ZeroCoin? Zcoin was proposed by Johns Hopkins University professor Matthew D.

Green, along with graduate students Ian Miers and Christina Garman. The team proposed Zcoin as an extension to the bitcoin protocol, adding true cryptographic anonymity to bitcoin transactions.

The team originally proposed ZeroCoin as a. Today, however, it’s a separate blockchain with its own currency. The team eventually launched Zcoin on September 28, 2016 to demonstrate the power of their ZeroCoin Protocol. ZeroCoin Conclusion Zcoin, or XZC or ZeroCoin, is a cryptocurrency introduced to solve problems with the. The currency has a number of unique features that distinguish it from bitcoin – including anonymity services and zero knowledge proofs. The currency was designed to showcase the power of the ZeroCoin Protocol. You can learn more about Zcoin, XZC, or ZeroCoin by visiting the official website online today at Zcoin.io.
