# GraphSense

> GraphSense is an open-source (MIT-licensed) cryptoasset analytics platform for Bitcoin, Ethereum, Tron, and other major UTXO- and account-model ledgers. It emphasizes full data sovereignty, algorithmic transparency, and scalability, and provides both an interactive investigation dashboard and a programmable REST API for cryptoasset analytics workflows. GraphSense was started in 2015 at the Austrian Institute of Technology (AIT) and is now developed in collaboration with the Complexity Science Hub. A hosted, near-real-time service is operated by Iknaio Cryptoasset Analytics GmbH (a separate company spun out of the original team).
