NFTracer: Tracing NFT Impact Dynamics in Transaction-Flow Substitutive Systems With Visual Analytics

Area of Science:

• Data Visualization
• Machine Learning
• Blockchain Technology

Background:

• Estimating Non-Fungible Token (NFT) project growth relies on understanding impact dynamics, including appeal diffusion and decay among stakeholders.
• Current machine learning approaches for impact dynamics lack interpretability and transparency, hindering informed decision-making for stakeholders.
• Analyzing heterogeneous NFT transaction data presents challenges for developing interactive and flexible decision-support tools.

Purpose of the Study:

• To develop an interactive visual analytics system for analyzing NFT project impact dynamics.
• To address the need for interpretable and transparent tools for stakeholders in the NFT market.
• To simulate and visualize the substitutive relationships and influence patterns within NFT ecosystems.

Main Methods:

• Conducted a formative study to define analysis criteria: substitution mechanisms, impact attributes, and stakeholder design requirements.
• Proposed the Minimal Substitution Model to represent NFT projects and their interactions as node-link graphs.
• Developed NFTracer, a multi-view visual analytics system integrating attribute-aware techniques for interactive analysis of NFT transaction data.

Main Results:

• NFT projects with higher similarity are more likely to substitute one another within the market.
• The impact of an NFT project is significantly influenced by the influx of new stakeholders and the project's 'freshness' or novelty.
• Case studies and user studies validated the informativeness, effectiveness, and usability of the NFTracer system.

Conclusions:

• The developed visual analytics system, NFTracer, provides an effective and interpretable method for understanding NFT impact dynamics.
• Stakeholder behavior and project attributes can be effectively embedded in visualization layouts for intuitive analysis.
• The findings offer valuable insights for stakeholders and project developers navigating the dynamic NFT market.
