A Blockchain-based Decentralized Electronic Marketplace for Computing Resources

Abstract

We propose a framework for building a decentralized electronic marketplace for computing resources. The idea is that anyone with spare capacities can offer them on this marketplace, opening up the cloud computing market to smaller players, thus creating a more competitive environment compared to today’s market consisting of a few large providers. Trust is a crucial component in making an anonymized decentralized marketplace a reality. We develop protocols that enable participants to interact with each other in a fair way and show how these protocols can be implemented using smart contracts and blockchains. We discuss and evaluate our framework not only from a technical point of view, but also look at the wider context in terms of fair interactions and legal implications.

Trading Application Based on Blockchain Technology

“…Another innovative approach, described in [6], is trading of computational power in a decentralized fashion, based on Ethereum platform. The proposed framework assumes that spare computational resources can be shared with entities and charged for the service.…”

Decentralized procurement mechanisms for efficient logistics services mapping - a design science research approach

“…In this paper, we define problem owners as logistic companies involved in procurement mechanisms. The problem is worth exploring as shippers oftentimes struggle to find qualified carriers as information asymmetry in procurement marketplaces is strong [2,3]. Indeed, existing procurement marketplaces frequently lack information transparency: for example, access to delivery histories, or allocation protocol can be restricted.…”

“…Indeed, existing procurement marketplaces frequently lack information transparency: for example, access to delivery histories, or allocation protocol can be restricted. As a consequence, data integrity of the carrier profiles may not be assured, or important services records may not be kept [2]. Moreover, the freight procurement platform controls all information flows which gives it a lot of centralized power and an incentive to keep the mapping of logistics services nontransparent for others [3].…”

“…A study conducted among 300 retailers across the UK, US, and Germany in 2018 demonstrates that the average yearly cost of failed deliveries per retailer is almost £200,000 [4]. Thus, FTSP mapping requires a technology that (1) leverages trusted delivery information to compute the QoS of carriers, (2) fosters power balance between partners, and (3) optimize the FTSP process.…”

SAIaaS: A Blockchain-Based Solution for Secure Artificial Intelligence as-a-Service

“…Finally, it is difficult to find such providers, as many datasets and algorithms exist. Those issues have been partially addressed by academic studies, whether by the construction of blockchain-enabled data marketplaces (e.g., [6]) or blockchain cloud monitoring for third-party computation [9]. However, there still is no end-to-end solution to allow clients to get a desired model in a decentralized way.…”
