# 5.4 Blockchain-Powered Automation and MLOps

To streamline the data annotation workflow, Labelfi incorporates blockchain-based automation and MLOps (Machine Learning Operations), creating an efficient pipeline for developers and data scientists.

* Smart Contracts for Task Management: Labelfi uses smart contracts to automate the assignment of annotation tasks. Contributors are automatically compensated in LBF tokens upon completion of their tasks, without the need for intermediaries \[21].
* Data Provenance and Auditing: Through blockchain, Labelfi tracks the provenance of all data and annotations, ensuring that the origin of the data can always be verified. This supports compliance with industry standards and auditing requirements \[22].
