Guest talk about storage solutions in Ethereum

Dear students,

we are pleased to invite you to an interesting talk about the recent development of storage solutions in Ethereum. Your attendance is not mandatory but we hope to see you there. The speaker is a colleague from University of Stavanger.

Speaker: Racin Nygaard
Place: Styrerom  4118, Ole-Dahls hus
Time: Friday 24th of January at 10:15

ABSTRACT OF THE TALK:

Riding on the blockchain wave, there has been a recent resurgence of P2P storage networks. Similarly to how public blockchains have the potential to pool CPU resources, the P2P storage networks promise to pool together the worlds hard drives, exploiting unused storage resources and thus creating cheap storage for everyone.

The storage networks aim to store as much data as possible off-chain, only keeping a minimum amount of metadata on the blockchain. At the same time, it is critical that the storage is reliable and resilient to data loss and corruption.

Our study focus on the storage network Swarm, a native layer of the Ethereum web3 stack, which aims at providing redundant storage for DApps, data and blockchain state data. Our contribution improves the resilience to failures by balancing storage and repairs. Our proof-of-concept is an optional add-on that interacts with the storage network to add redundancy on the stored data.
