DMarket is a decentralized game asset marketplace. The marketplace covers a wide variety of games and turns virtual items into real commodities that can be traded on the blockchain. The idea of tokenization is central to the blockchain where any item can be represented as a token on the blockchain. This creates an emerging economy around digital assets where they become real items. There are an estimated 2.3 billion gamers worldwide and ample opportunity to monetize digital assets. The gaming economy is estimated at $450 billion There are two types of assets available on DMarket. The first type is a virtual Steam item. This Steam item is an in-game asset this is available for a specific game. At the moment there is a horde of items available for Counter-Strike: Global Offensive. There is also a DMarket Blockchain item that is an internal blockchain item that can be traded on the DMarket blockchain. Users can sell Steam items for US Dollars (USD) or DMarket items for USD or DMC, the internal DMarket cryptocurrency. Users can buy Steam items for USD or DMC or DMarket items for DMC. In order to sell Steam items on DMarket, users have to connect their Steam account to their DMarket account. DMarket blockchain items can be traded without connecting to Steam. Users have to register on DMarket. This creates a DMC wallet for them where they can store their DMC currency and DMarket items. The DMarket platform also has its own block explorer. All wallets and transactions are recorded in the public blockchain. DMarket has a future-proof use case as the demand for a universal gaming trading platform is imminent. Strategic partnerships between game title developers, the gaming community and gamers will ensure that DMarket lives well beyond its proprietary blockchain phase.
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.
