We focus on constructing an automatic pricing and matching mechanism based on liquidity pools. Subsequently, mathematical modeling and simulations reveal the slippage generation mechanism in data liquidity pools under trading shocks and imbalances. To address these issues, a novel dual slippage optimization mechanism integrating dynamic trade splitting and alternating order sorting is proposed, which decomposes orders into sub-orders and reorganizes their timing, establishing a dynamic equilibrium model. Experiments show that the method reduces the average slippage amplitude from 2.1% to 0.5%, representing a 76.2% reduction, and significantly enhances price stability and market efficiency. This research explores the mechanism of applying AMM to data asset trading and mitigates the limitations of AMM in this scenario, providing a theoretical and empirical foundation for building low-cost, high-fairness data trading systems through mechanism innovation and technical optimization.<\/jats:p>","DOI":"10.3390\/a19060465","type":"journal-article","created":{"date-parts":[[2026,6,8]],"date-time":"2026-06-08T05:43:46Z","timestamp":1780897426000},"page":"465","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["ESS-LP: An Effective Slippage Scheme Based on Liquidity Pools for Data Trading"],"prefix":"10.3390","volume":"19","author":[{"given":"Huayou","family":"Si","sequence":"first","affiliation":[{"name":"The School of Information Engineering, China Jiliang University, Hangzhou 310018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mengyang","family":"Li","sequence":"additional","affiliation":[{"name":"The School of Information Engineering, China Jiliang University, Hangzhou 310018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7941-3320","authenticated-orcid":false,"given":"Yuanyuan","family":"Qi","sequence":"additional","affiliation":[{"name":"The School of Information Engineering, China Jiliang University, Hangzhou 310018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0394-4635","authenticated-orcid":false,"given":"Neal N.","family":"Xiong","sequence":"additional","affiliation":[{"name":"The Department of Computer Science, Southern New Hampshire University, Manchester, NH 03106, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Chen","sequence":"additional","affiliation":[{"name":"The School of Information Engineering, China Jiliang University, Hangzhou 310018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8386-272X","authenticated-orcid":false,"given":"Loc Nguyen","family":"The","sequence":"additional","affiliation":[{"name":"The School of Information and Communication Technology, Hanoi University of Science and Technology, Hanoi 100000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shichong","family":"Wang","sequence":"additional","affiliation":[{"name":"The School of Information Engineering, China Jiliang University, Hangzhou 310018, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,7]]},"reference":[{"key":"ref_1","first-page":"25","article-title":"Promoting the Data Element Marketization: Progress, Problems and Solution","volume":"41","author":"Ren","year":"2024","journal-title":"Doc.
