Overview

This package contains the source code for Novamene: An Efficient Lightweight DoS-Resilient Transaction Pool for Ethereum Clients

Abstract

The Ethereum transaction pool plays a key role in processing and disseminating live transactions over the network. However, growing transaction loads and spam attacks cause a significant increase in memory consumption of the transaction pool. This not only puts a strain on the resources of Ethereum nodes but also leads to dropped transactions, processing delays, spikes in transaction fees, and exposes the network to sophisticated attacks. We present Novamene, a novel transaction pool solution for resource-constrained nodes which provides resilience against spam and dust attacks and contributes to the overall health of the network. Novamene reconfigures the transaction pool using bloom filter constructions to fingerprint live transactions as an alternative to maintaining a complete transaction record. We implement Novamene in C++ and benchmark it using a unique 30-day Ethereum transactions dataset. Novamene caters to increased transaction flows with minimal RAM consumption, handling 400 MB worth of transaction load in 4 MB, and processing transactions with 99.99% accuracy. We simulate congestion and spam events, up to threefold the peak traffic rate witnessed on the Ethereum network, and demonstrate that Novamene maintains high accuracy. Novamene does not require a hard fork, it can be adapted to other cryptocurrencies as a security and optimization solution, and may even be used to build lightweight clients.
