Zcash is a decentralized and open-source cryptocurrency that offers privacy and selective transparency of transactions. Zcash payments are published on a public blockchain, but the sender, recipient, and amount of a transaction remain private. Zcash is based on peer-reviewed cryptographic research, and built by a security-specialized engineering team on an open source platform based on Bitcoin Core's battle-tested codebase. Our improvement over Bitcoin is the addition of privacy. Zcash uses advanced cryptographic techniques, namely zero-knowledge proofs, to guarantee the validity of transactions without revealing additional information about them. How Zcash works Zcash encrypts the contents of shielded transactions. Since the payment information is encrypted, the protocol uses a novel cryptographic method to verify their validity. Zcash uses a zero-knowledge proof construction called a zk-SNARK, developed by our team of experienced cryptographers based on recent breakthroughs in cryptography. These constructions allow the network to maintain a secure ledger of balances without disclosing the parties or amounts involved. Instead of publicly demonstrating spend-authority and transaction values, the transaction metadata is encrypted and zk-SNARKs are used to prove that nobody is cheating or stealing. Zcash also enables users to send public payments which work similarly to Bitcoin. With the support for both shielded and transparent addresses, users can choose to send Zcash privately or publicly. Zcash payments sent from a shielded address to a transparent address reveal the received balance, while payments from a transparent address to a shielded address protect the receiving value.

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.
