Zcoin (XZC) is a cryptocurrency focused on privacy and decentralization. It is the first coin to implement the Zerocoin protocol that enables financial privacy through the power of zero knowledge proofs with a focus on making privacy easy to use. It is also set to be the first to release MTP an ASIC resistant, anti-botnet proof of work algorithm that remains lightweight to verify to ensure fair distribution of coins and decentralized security. Zcoin is an open source decentralized cryptocurrency that focuses on achieving privacy and anonymity for its users while transacting. To achieve this privacy and anonymity, Zcoin uses zero-knowledge proofs via Zerocoin protocol which is one of the most cited cryptography papers at this point in time. In other words, when you transact using Bitcoin or Ethereum or something similar, your transaction history is always linked to your coins by default which makes you vulnerable. That, because all it takes is one link to your personal information or IP to find out the origin of the coins.However, if you transact using Zcoin’s Zerocoin feature, none of your transaction histories is linked to the actual coins and only the receiver and sender know that you have actually exchanged funds. Zerocoin is a cryptocurrency proposed by Johns Hopkins University professor Matthew D. Green and graduate students Ian Miers and Christina Garman as an extension to the Bitcoin protocol that would add true cryptographic anonymity to Bitcoin transactions. Zerocoin was first implemented into a fully functional cryptocurrency released to the public by Poramin Insom, as Zcoin who is also the lead developer, in September 2016. At the initial stage, Zcoin uses the Lyra2z algorithm for proof of work, then they will transition to a Merkle Tree proof of work algorithm, known as MTP. MTP is a unique memory hard algorithm that aims to solve several problems. Memory hard algorithms help prevent the development of ASICs which lead to centralized mining farms. Memory hard algorithms also prevent the use of botnets infecting computers for mining purposes. If a botnet was using up multiple gigs of memory, you’d be likely to notice something is wrong. “The basic concept is that it should establish the same price/cost for a single computation unit on all platforms meaning that there is no single device that should gain a significant advantage over another for the same price hence promoting egalitarian computing.
The Raiden Network is an off-chain scaling solution, enabling near-instant, low-fee and scalable payments. It’s complementary to the Ethereum blockchain and works with any ERC20 compatible token. The Raiden project is work in progress. Its goal is to research state channel technology, define protocols and develop reference implementations. The introduction of payment channels, specifically the type first described by the Lightning Whitepaper (which introduced the Lightning Network), seeks to fix the scalability and congestion issues that currently plague blockchain technology. While the Lightning Network operates on the Bitcoin blockchain, Raiden introduces a comparable solution for the Ethereum network. There are several key features of the Raiden Network Token. Expedited transfer confirmations (<1 second ). Current transfers on the Ethereum blockchain can take a few seconds to minutes. Private transfers that are not viewable on the global ledger. Solve scalability issues so that Ethereum can create mass adoption, allowing Ethereum to become the peer-to-peer, global payments infrastructure with electronic cash that it was initially designed for. Low fee transactions. Micropayment capability that works in union with any ERC-20 token. The Raiden Network project is being developed by Germany’s Brainbot Technologies AG, a software company devoted to blockchain protocol development. Founded in the year 2000 by Heiko Hees, it currently has between 11 to 50 employees in offices among Berlin, Mainz, and Copenhagen. Also the founder of PediaPress, Hees has been a core developer of Ethereum since March 2014. Being a core developer for Ethereum, it is evident on how the founder sees the flaws in the current its present protocol with ways to improve it. Interestingly enough, the website does not include RDN as one of their main blockchain developments, which could be attributed to the difficulty of highlighting a wide variety of projects they are currently undertaking on one page. However, there are no updates on the status of the Raiden Network Project on either Twitter nor Medium since December 1st, 2017. Raiden can be used for a wide variety of applications and purposes such as Micropayments For Content Distribution, Decentralized M2M Markets, API Access and Fast Decentralized Exchanges.'
