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.

MATRIX AI Network (MAN) is a global open-source, public, intelligent blockchain-based distributed computing platform and operating system that combines artificial intelligence (AI) and blockchain. MATRIX was created to make blockchains faster, more flexible, more secure, and more intelligent. Besides boasting an impressive 50.000 transactions per second, there are a couple of features which makes Matrix AI Network stand out from its competitors. Matrix adopts a Hybrid PoS + PoW consensus mechanism instead of the traditional Hash computations. The mechanism makes use of value-added computation through the use of the Markov Chain Monte Carlo (MCMC) computations. This computation set is to be used as the Proof-of-Work protocol. This allows the mining process to not only generate MAN tokens but to also be used to power real-world applications. Currently being used in collaboration with Beijing cancer Research hospital to improve speed and accuracy of a cancer diagnosis. While the project seems ambitious with the integration of a working AI in so many areas, the AI-part is already done. Matrix now only has to deliver a working blockchain solution. MATRIX will be launching several community activities after its testnet launch, including a Bug Bounty Program and a Dapp competition, as well as introducing the MATRIX Blockchain Browser and Online Wallet Prototype. Details and instructions will be shared over the coming weeks. Full manner is set to launch December 2018. The MATRIX mining machine is set to launch for sale end of the year 2018.
