Web3 中的程式化事实

Stylized facts in Web3

Wei-Ru Chen, A. Christian Silva, Shen-Ning Tung

AI总结:

本文通过多时间尺度统计分析 Web3 代币收益分布与尾部特征,发现 CEX 与 DEX 资产具有相似程式化事实,并将其归因于套利机制。

摘要:

本文对 Web3 生态系统进行了全面的统计分析,在多个时间尺度上将各类 Web3 代币与传统金融资产进行比较。我们考察了多种代币收益的概率分布、尾部行为及其他关键程式化事实,这些代币涵盖去中心化交易所、流动性池和中心化交易所。尽管功能存在差异,大多数代币都表现出已被充分证实的经验事实,包括收益的无条件概率密度具有厚尾并逐渐趋于高斯分布,以及波动率聚集。此外,我们比较了在中心化交易所(CEX)和去中心化交易所(DEX)上交易的资产,发现尽管交易机制不同且长期表现常常分化,DEX 仍表现出相似的程式化事实。我们认为,这种相似性可归因于套利者努力维持中心化与去中心化价格相近。本研究有助于更好地理解 Web3 代币的动态以及 CEX 与 DEX 市场之间的关系,并对快速发展的 DeFi 领域中的风险管理、定价模型和投资组合构建具有重要意义。这些结果丰富了不断增长的加密货币市场文献,并提供了可指导更准确 DeFi 市场模型开发的洞见。

英文摘要:

This paper presents a comprehensive statistical analysis of the Web3 ecosystem, comparing various Web3 tokens with traditional financial assets across multiple time scales. We examine probability distributions, tail behaviors, and other key stylized facts of the returns for a diverse range of tokens, including decentralized exchanges, liquidity pools, and centralized exchanges. Despite functional differences, most tokens exhibit well-established empirical facts, including unconditional probability density of returns with heavy tails gradually becoming Gaussian and volatility clustering. Furthermore, we compare assets traded on centralized (CEX) and decentralized (DEX) exchanges, finding that DEXs exhibit similar stylized facts despite different trading mechanisms and often divergent long-term performance. We propose that this similarity is attributable to arbitrageurs striving to maintain similar centralized and decentralized prices. Our study contributes to a better understanding of the dynamics of Web3 tokens and the relationship between CEX and DEX markets, with important implications for risk management, pricing models, and portfolio construction in the rapidly evolving DeFi landscape. These results add to the growing body of literature on cryptocurrency markets and provide insights that can guide the development of more accurate models for DeFi markets.
