# 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 by the Complexity Science Hub in close collaboration with Iknaio. A hosted, near-real-time service is operated by Iknaio Cryptoasset Analytics GmbH (a separate company spun out of the original team).
