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.

Reserve aims to build a stable, decentralized, asset-backed cryptocurrency and a digital payment system that scales supply with demand and maintains 100% or more collateral backing. Ultimately, Reserve’s goal is to create a universal store of value – particularly in regions with unreliable banking infrastructure and regions where hyperinflation is an issue. The Reserve system will interact with three kinds of tokens: (1) The Reserve token (RSV), which is a stable cryptocurrency that can be held and spent the way we use normal fiat money; (2) The Reserve Rights token (RSR), a protocol token used to facilitate the stability of RSV. (3) A growing variety of tokenized real-world assets (such as other stablecoins) that are held by the Reserve smart contract to back RSV.
