Towards Composable Privacy

Addressing State Denial challenges with Silent Protocol's solution

Requirements for Composable Privacy

To overcome the limitations of State Denial, a framework must integrate privacy-preserving mechanisms with composability in a decentralized, permissionless environment. Such a framework must enable:

1. Aggregated Global State Access: Mechanisms to share global state information seamlessly across applications in a privacy-preserving manner, ensuring data remains secure.

2. Inter-function Calls with Privacy: Protocols to enable inter-function calls between private applications while maintaining strict data confidentiality.

3. Ecosystem Interoperability: A unified system architecture that supports collaborative functionalities across applications, fostering the development of privacy-preserving ecosystems.

The State Denial Paradox

Due to the nature of privacy, sharing an application’s state with an external entity creates a paradox: you can either make an application private or make it composable with the rest of the ecosystem. However, in a privacy-preserving framework, allowing shared states at the universal level becomes difficult, hindering the creation of interconnected applications. This State Denial challenge is the primary obstacle to the adoption and advancement of privacy-preserving technologies.

Frameworks relying solely on ZK proofs cannot fully resolve State Denial, as they struggle to balance privacy and composability.

Silent Protocol’s Solution: EZEE

Silent Protocol introduces EZEE, a novel framework that builds upon a new system architecture to enable composable privacy, addressing State Denial by introducing a new type of privacy known as composable privacy. EZEE facilitates global state sharing, allowing users to post state updates with arbitrary dimension expansion while maintaining privacy, by processing inter-function calls through ZK proofs, ensuring encryption, and using message passing as a primitive to securely handle application interactions; this allows users to conceal their personal details while interacting with applications that process interoperable computations, making EZEE the first framework to achieve true composable privacy in a decentralized system.
