Improving Quality of Service for Users of DAG-based Distributed Ledgers

TL;DR

This paper proposes a user-node interaction mechanism for DAG-based distributed ledgers like IOTA, aiming to improve service quality by guiding users to select high-quality nodes based on advertised indicators, thus enhancing usability.

Contribution

It introduces a novel user-node interaction policy for DAG-based ledgers that reduces poor service experiences, supported by simulation validation.

Findings

Effective in reducing poor quality of service incidents

Users can select better nodes based on quality indicators

Simulation results demonstrate improved network usability

Abstract

An outstanding problem in the design of distributed ledgers concerns policies that govern the manner in which users interact with the network. Network usability is crucial to the mainstream adoption of distributed ledgers, particularly for enterprise applications in which most users do not wish to operate full node. For DAG-based ledgers such as IOTA, we propose a user-node interaction mechanism that is designed to ensure the risk of a user experiencing a poor quality of service is low. Our mechanism involves users selecting nodes to issue their transactions to the ledger based on quality of service indicators advertised by the nodes. Simulation results are presented to illustrate the efficacy of the proposed policies.
