The problem

The blockchain is one of the most important recent inventions, enabling business and individuals to instantly send money and information over the internet, without the need for trusted third parties. However, current modelling completely forgoes privacy, with the entirety of data and amounts transacted between parties exposed to the public, whilst most real-world applications - health, financial, IoT, etc - require details of their operations to remain undisclosed and are not compatible with a public blockchain system.

Our solution

We are building a next-generation decentralized platform that enables secure value transfers and smart contract execution, in complete confidentiality and with strong correctness guarantees. Glyff, like Ethereum, allows development of decentralized applications, but with a key difference : the ability of concealing data from the computing nodes. This enables developers to include sensitive data in their smart-contracts, directly on-chain, without compromise on security.
