+# Codatta Crypto Address Annotations (Sample)
+
+## Dataset Summary
+
+This repository contains a **10,000-row sample** of the Codatta Crypto Address Annotations database. The full dataset comprises over **500 million** labeled address pairs across multiple blockchains.
+
+The data provides critical metadata such as entity names, categories (e.g., Exchanges, DeFi, Scam), and risk levels. It is curated through a unique hybrid approach, combining high-quality community contributions from the **Codatta** platform and collaborative data from the **Microscope Protocol**.
+
+By bridging crowdsourced intelligence with standardized open protocols, this dataset aims to solve the problem of fragmented and siloed blockchain metadata.
+
+
+## Data Sources & Protocols
+
+The high fidelity of this dataset is achieved through two primary sources:
+
+1.  **Codatta Platform:** Data aggregated from Codatta's decentralized data intelligence network, verified by the contributor community.
+    
+2.  **Microscope Protocol:** We utilize the Microscope Protocol, an open-source initiative for collaboratively labeling crypto addresses.
+    * **Official Website:** [https://microscopeprotocol.net/](https://microscopeprotocol.net/)
+    * **Context:** [Microscope: Protocol for Collaboratively Labeling Crypto Addresses (Coinbase Blog)](https://www.coinbase.com/blog/microscope-protocol-for-collaboratively-labeling-crypto-addresses)
+
