2023-02-19 admin

Our recent work, “A Comparative Analysis of Centralized and Decentralized Developer Autonomous Organizations Managing Conflicts in Discussing External Crises”, is accepted to be published in IEEE Transactions On Computational Social Systems. Understanding how online developer communities address conflicts that arise in discussions is essential to the collaboration issue. However, few studies have focused on the […]

Our work “Altruistic and Profit-oriented: Making Sense of Roles in Web3 Community from Airdrop Perspective” is accepted by ACM CHI’23

2023-01-152023-01-19 admin

Many decentralized applications (DApps) issue airdrops to early supporters for their contributions. However, most eligible users are motivated by financial profit or preferential access to tokens with governance rights to obtain quick cash. In this paper, we take ParaSwap as a representative example, trying to evaluate the Web 3.0 community and the effectiveness of allocation principles through the analysis of eligible users’ behavior and token transaction network.

Our recent work titled “Towards Understanding Player Behavior in Blockchain Games: A Case Study of Aavegotchi” is accepted by the 17th International Conference on the Foundations of Digital Games (FDG 2022). Blockchain games introduces unique gameplay and incentive mechanisms by allowing players to be rewarded with in-game assets or tokens through financial activities. In practice, […]

Our paper “Economic Analysis of Decentralized Exchange Market with Transaction Fee Mining” received the Best Paper Award from ACM BSCI’22!

2022-05-312023-02-19 admin

In this paper, we establish the DEX market with transaction fee mining and formulate our model based on the Hotelling model. Besides, we propose a two-stage game to formulate the interaction between DEXs and users and derive the equilibriums under different conditions of two parameters: the transaction cost difference and users’ stickiness. We show that though the service provider with a lower transaction cost can win the market, users’ stickiness can offset the market advantage. Thus, incentivizing users with transaction fee mining has become a crucial strategy in the duopoly competition.
