从匿名加密货币交易中推断单向套利
文章 arXiv papers · 作者: Eugenio Nerio Nemmi et al.
总结
本研究提出一种方法,用于识别中心化加密货币交易所现货交易记录中可能存在的单向套利(OWA)序列。公开数据缺少交易者身份或钱包地址,因此该方法从匿名交易中推断关联交易序列,让研究人员估算此类活动的发生频率、总交易量和利润。
该方法应用于 Binance 五年和 Kraken 九年的数据,在 Binance 上识别出数亿个可能的序列,在 Kraken 上识别出近两百万个。估算总利润为正,但扣除费用后,每个序列的平均利润不足一美元。研究还报告称,随着单个序列盈利能力下降,序列发生速度逐渐加快。这些是推断出的模式,并非直接识别出的交易者;摘要没有详细说明检测规则或估算的不确定性。结果显示价格差异反复出现,但未能确定哪些市场条件会使特定序列获利。
核心观点
- 可通过匿名现货交易分析推断可能存在的单向套利序列。
- 研究将该方法应用于 Binance 和 Kraken 的交易历史。
- 估算的总利润为正,但扣费后每个序列的平均利润很低。
- 推断出的序列速度加快,而其单个序列的盈利能力下降。
- 有利于套利获利的具体条件仍未明确。

# A Truckload of Satoshis: Detecting and Measuring One-Way Arbitrage in the Wild # A Truckload of Satoshis: Detecting and Measuring One-Way Arbitrage in the Wild Centralized cryptocurrency exchanges (CEXes) enable fast off-chain conversions between hundreds of coins. It is an open question which algorithmic trading patterns occur on these platforms. A major challenge to measuring CEXes is that their public trade data does not contain addresses or trader identifiers allowing linkage. We propose a novel methodology to infer one-way arbitrage (OWA) trading in anonymized spot trade data from CEXes. We identify 402 M likely OWA sequences in 5 years of trading on Binance (and almost 2 M during 9 years on Kraken), accounting for 0.94 % and 0.13 % of the total traded volume, respectively. While we estimate total profits of $31.2 M on Binance and $975 k on Kraken, profits from individual OWA sequences are less than $1 on average after accounting for trading fees. We also observe that OWA has become faster over time, while the profitability of individual sequences has decreased. Our findings highlight that pricing discrepancies regularly occur in CEXes, and raise questions for future work to identify the precise circumstances that enable profitable OWA.
