[Invited talk] Building a Disaster-resilient Storage Layer for Next Generation Networks: The Role of Redundancy

TL;DR

This paper discusses designing a resilient storage layer for web3 networks using redundancy, focusing on Swarm's ability to improve fault tolerance with minimal latency increase.

Contribution

It introduces redundancy strategies in Swarm to enhance failure resilience, balancing repair mechanisms and storage costs in a decentralized storage system.

Findings

Enhanced fault tolerance in Swarm through redundancy

Balanced repair and storage to improve resilience

Slight latency increase with improved reliability

Abstract

Blockchain is the driving force behind a myriad of decentralized applications (dapps) that promise to transform the Internet. The next generation Internet, or web3, introduces a "universal state layer" to store data in p2p networks. Swarm, a native layer of the Ethereum web3 stack, aims at providing redundant storage for dapp code, data, as well as, blockchain and state data. Based on a diploma verification dapp use case, we share insights on the role of redundancy strategies in designing a reliable storage layer. Our proof-of-concept improves Swarm's resilience to failures by balancing repairs and storage, with a slightly added latency.
