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.

A Next Generation Blockchain for a Programmable Economy Platform : The Engine Behind the Most Dynamic Enterprise Infrastructure EdenChain is a blockchain technology designed specifically with enterprises in mind. It is a fast, secure and reliable third generation blockchain platform that allows all tangible and intangible values to be capitalized through smart contracts, enabling people to freely trade through the internet without intermediaries There exist a plethora of tradable asset classes in the world, such as stocks, bonds, real estate and commodities amongst money others. Individuals buy and sell these assets for various financial and non-financial purposes. As technology continues to develop, more unique asset classes have begun to emerge, such as copyrights, insurance policies, and derivatives, which all contain tradeable value when certain conditions are met. With EdenChain, existing assets can be replaced with blockchain-based tokens and their ownership can be registered; the necessary conditions can be specified through smart contracts according to the characteristics of the asset.
