Incentive Mechanisms in Peer-to-Peer Networks — A Systematic Literature Review

Centralized networks inevitably exhibit single points of failure that malicious actors regularly target. Decentralized networks are more resilient if numerous participants contribute to the network’s functionality. Most decentralized networks employ incentive mechanisms to coordinate the participation and cooperation of peers and thereby ensure the functionality and security of the network. This article systematically reviews incentive mechanisms for decentralized networks and networked systems by covering 165 prior literature reviews and 178 primary research papers published between 1993 and October 2022. Of the considered sources, we analyze 11 literature reviews and 105 primary research papers in detail by categorizing and comparing the distinctive properties of the presented incentive mechanisms. The reviewed incentive mechanisms establish fairness and reward participation and cooperative behavior. We review work that substitutes central authority through independent and subjective mechanisms run in isolation at each participating peer and work that applies multiparty computation. We use monetary, reputation, and service rewards as categories to differentiate the implementations and evaluate each incentive mechanism’s data management, attack resistance, and contribution model. Further, we highlight research gaps and deficiencies in reproducibility and comparability. Finally, we summarize our assessments and provide recommendations to apply incentive mechanisms to decentralized networks that share computational resources

Cryptonetworks - The incentive-based Economics of Blockchain

Blockchain technology has the novel ability to ‘create' trust in a decentralised environment. With this technology, third-parties and middlemen are no longer necessary to enforce transactions. Instead, blockchain uses decentralised consensus protocols and embedded logic to enforce contracts. The applications of blockchain are vast and include cryptonetworks, the culmination of blockchain and crypto tokens. Cryptonetworks can have an impact on the business models of firms, both in terms of cost structure and value creation. By blending the functionality of centralised platforms with the community-orientated nature of the original open protocols of the internet, cryptonetworks enable value creation to be correctly assigned to the actual content creators through tokens. The work of Ronald Coase illustrated the need for firms to overcome the transaction costs of operating within the market. Cryptonetworks, however, provide an alternative ‘middle ground' option to the firm and the market, allowing both to benefit from reduced transaction costs and incentive maximisation of the market. In addition, the implementation of economics in today's cryptonetworks, often referred to as ‘cryptoeconomics', remains conventional and conservative, placing a limit on the potential of cryptonetworks. By revaluating and reconstructing today's value measurement criteria, cryptonetworks have the potential to move beyond a single ‘Hayekian price' and instead incorporate multiple other indexes that better measure and capture value creation as it pertains to wider social issues of production, distribution, and consumption of goods and services. Finally, this thesis incorporates a case study on the MakerDAO stablecoin as a practical illustration of a cryptonetwork
