Abhishek A. Singh, Aasim Khan, Sharad Mehrotra, Faisal Nawab

TL;DR
TransEdge is a distributed system designed for untrusted edge environments, enabling efficient, consistent read-only transactions with minimal communication rounds, significantly outperforming existing Byzantine systems.
Contribution
It introduces a novel dependency tracking scheme and protocols that support fast, consistent read-only transactions in untrusted edge computing environments.
Findings
Achieves 9-24x speedup over existing Byzantine systems
Supports reading from multiple partitions with one or two rounds
Optimized for untrusted, edge computing scenarios
Abstract
We propose Transactional Edge (TransEdge), a distributed transaction processing system for untrusted environments such as edge computing systems. What distinguishes TransEdge is its focus on efficient support for read-only transactions. TransEdge allows reading from different partitions consistently using one round in most cases and no more than two rounds in the worst case. TransEdge design is centered around this dependency tracking scheme including the consensus and transaction processing protocols. Our performance evaluation shows that TransEdge's snapshot read-only transactions achieve an 9-24x speedup compared to current byzantine systems.
