RUES

Rusk Universal Events System (RUES)

The Rusk Universal Event System (RUES) is an integral part of the architecture of Dusk, providing a powerful mechanism for handling real-time communication with an event-driven approach.

RUES is designed to handle binary proofs, binary streams, and on-demand event-driven data, making it ideal for applications that need to process binary proofs or continuous binary data streams. It also enables on-demand data dispatching and real-time notifications, supporting applications like wallet operations that require high-performance binary data handling. This is achieved by avoiding the need to convert data to JSON or base64.

Use of RUES

RUES is deeply integrated into Dusk’s architecture, playing a critical role in various components.

Smart Contracts

Contracts in Dusk can emit arbitrary events following a state change, heavily depending on transaction execution. This capability allows contracts to trigger events based on their internal logic and interactions, facilitating complex workflows and state management.

Consensus Mechanism

The consensus layer can emit events associated with failed iterations, particularly when transactions are not executed. This functionality helps in diagnosing and responding to consensus-related issues, providing insights and triggers for corrective actions.

Mempool Management

The mempool, which temporarily holds transactions before they are included in a block, can emit events after certain conditions are met, such as transaction expiration or reaching a memory/space threshold. These events help manage the mempool’s state and ensure efficient transaction processing.

Interoperability

Exogenous events from another chain can trigger endogenous events within Dusk. These events can lead to the creation of new transactions by clients or a set of validators, facilitating seamless cross-chain operations and data exchange.
