To Incentivize or Not: Impact of Blockchain-Based Cryptoeconomic Tokens on Human Information Sharing Behavior

Abstract

Cryptoeconomic incentives in the form of blockchain-based tokens are seen as an enabler of the sharing economy that could shift society towards greater sustainability. Nevertheless, knowledge of the impact of these tokens on human sharing behavior is still limited and this poses a challenge to the design of effective cryptoeconomic incentives. This study applies the theory of self-determination to investigate the impact of such tokens on human behavior in an information-sharing scenario. By utilizing an experimental methodology in the form of a randomized control trial with a 2x2 factorial design involving 132 participants, the effects of two token incentives on human information-sharing behavior are analyzed. Individuals obtain these tokens in exchange for their shared information. Based on the collected tokens, individuals receive a monetary payment and build reputation. Besides investigating the effect of these incentives on the quantity of shared information, the study includes quality characteristics of the information, such as accuracy and contextualization. The focus on quantity while excluding quality has been identified as a limitation in previous work. In addition to confirming previously known effects such as a crowding-out of intrinsic motivation by incentives, which also exists for blockchain-based tokens, the findings of this paper point to a hitherto unreported interaction effect between multiple tokens when applied simultaneously. The findings are critically discussed and put into the context of recent work and ethical considerations. The theory-basedempirical study is of interest to those investigating the effect of cryptoeconomic tokens or digital currencies on human behavior and supports the community in the design of effective personalized incentives for sharing economies.

Decentralized justice: state of the art, recurring criticisms and next-generation research topics

“…Smart contracts are unable to resolve this situation, as the code cannot evaluate whether the delivered video complies with the agreed aesthetic and functional specifications Ast, 2022). Contracts in general are incomplete in the sense that they cannot foresee all of the potential for disagreement that could arise, thus necessitating a dispute resolution system (Ballandies, 2022).…”

Collective privacy recovery: Data-sharing coordination via decentralized artificial intelligence

“…They involve the three data-sharing criteria that model the involved trust (data collectors) and risks (data type and context), and they are the ones that explain malleable data-sharing behaviors ( 8 , 15 , 39 ). This large spectrum comes in contrast to earlier experiments and field tests made within a context and involving a specific data-sharing scenario such as online social lending ( 40 ), crowdfunding ( 41 ), and commerce ( 15 , 17 , 42 , 43 ).…”

Review of Blockchain Tokens Creation and Valuation

“…The authors also mention competition management as a challenge, and as advantages, the ease of information sharing and the improvement through competition. Ballandies [71] proposes the use of self-determination theory to investigate the impact of tokens for human behavior. The study analyses the effect of applying blockchain tokens for creating personalized incentives in the context of sharing economies.…”
