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.

For the first time in the history, opportunity, technology, as well as legal and social conditions are favourable and ready for the Robotina Platform to step onto the stage. Internet of Things, Blockchain Technology (enabling smart contracts) and Artificial intelligence bring great benefits to users and investors. Connected to the Robotina Platform, an enabling Universe, empowered people will save the electricity by using smart grids in order to save and earn money and reduce the pollution of our planet. We won’t do more, we will just do it smarter! The Robotina Platform will be a vertical, high-tech all-inclusive enabling solution, consisting of connected Internet of Things (IoT) elements (things, processes, data, people) and the Power Platform (PP). It will use Smart Rules, Artificial Intelligence and Blockchain technologies. It will be run in the cloud, available as a service. Robotina Platform and connected IoT will execute thousands of calculations per second. Each calculation will result in a small benefit and a small slice of revenue, which will accumulate every second. At the end of the day, this will become the driving force of the business.
