Contribution

It introduces a modular framework for simulating permissioned blockchains with support for multiple protocols and malicious actors, enhancing private blockchain assessment tools.

Findings

Supports multiple permissioned blockchain protocols.

Simulates malicious authorities and transaction variability.

Facilitates evaluation of blockchain solutions for logistics.

Abstract

In this paper, we present Talaria, a novel permissioned blockchain simulator that supports numerous protocols and use cases, most notably in supply chain management. Talaria extends the capability of BlockSim, an existing blockchain simulator, to include permissioned blockchains and serves as a foundation for further private blockchain assessment. Talaria is designed with both practical Byzantine Fault Tolerance (pBFT) and simplified version of Proof-of-Authority consensus protocols, but can be revised to include other permissioned protocols within its modular framework. Moreover, Talaria is able to simulate different types of malicious authorities and a variable daily transaction load at each node. In using Talaria, business practitioners and policy planners have an opportunity to measure, evaluate, and adapt a range of blockchain solutions for commercial operations.
