defi-liquidations
收藏资源简介:
Chainticks DeFi Liquidations 是一个标准化的去中心化金融(DeFi)清算事件数据集,数据来源于公共区块链日志的解码。该数据集以 Parquet 文件格式存储,按日期分区组织(例如 liquidations/date=YYYY-MM-DD/),便于高效查询和处理。每个分区包含多个 Parquet 文件(如 part-0000.parquet),并附带元数据文件:_schema.json 定义数据模式,_manifest.json 提供文件清单,LATEST_DATE.txt 指示最新数据日期。数据行严格限定为 source_kind 字段值为 on_chain_event 的记录,确保数据源自链上事件,不包括场所 REST/API 转售数据。数据集适用于金融和加密货币领域的研究与分析,可作为追加式市场上下文,支持使用 pandas、DuckDB 或 Polars 等工具进行数据处理。使用时需注意时间戳为 UTC 时区,并应在下游分析中保留 source_kind 字段以追踪数据来源。Chainticks 为独立实体,与数据所涉及的协议、中继、场所或政府机构无关联。
Chainticks DeFi Liquidations is a standardized decentralized finance (DeFi) liquidation event dataset, with data derived from decoded public blockchain logs. This dataset is stored in Parquet file format and organized via date-based partitioning (e.g., liquidations/date=YYYY-MM-DD/) to facilitate efficient querying and processing. Each partition contains multiple Parquet files (such as part-0000.parquet), and is accompanied by metadata files: _schema.json defines the data schema, _manifest.json provides the file manifest, and LATEST_DATE.txt indicates the latest data date. Data rows are strictly restricted to records where the source_kind field has a value of on_chain_event, ensuring that all data originates from on-chain events and excludes data resold via REST/API interfaces from trading venues. This dataset is suitable for research and analysis in the finance and cryptocurrency fields, and can serve as appendable market context to support data processing with tools including pandas, DuckDB, or Polars. When using the dataset, please note that all timestamps are in UTC timezone, and the source_kind field should be retained in downstream analyses to trace the data provenance. Chainticks is an independent entity and has no affiliation with any protocols, relays, trading venues, or government agencies associated with the dataset.
