Med Chain aims to create a new trading lifestyle of C2M through the decentralization, non-tamperable and traceability of blockchain, combined with the actual situation of the e-commerce industry, reducing the transaction cost of consumers and improving the production efficiency of manufacturers. Globalized peer-to-peer trading is integrated into every aspect of life, and everyone can trade and everything can be traded. Peer-to-peer trading lifestyle: Med Chain expects to popularize C2M trading models into people's daily lives through blockchain technology, open up trust barriers between consumers and manufacturers, reduce trust costs, and achieve peer-to-peer customized e-commerce transactions. Global e-commerce bottom-level public chain: Med Chain expects to use POS and DPOS consensus mechanism to establish a global e-commerce transaction public chain, establish a transaction credit system based on blockchain technology, product copyright traceability system, intelligent payment system, and transaction after-sales arbitration system. The open data system is open to global developers, allowing blockchain technology to serve all walks of life in e-commerce.
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.
