 - **Model-agnostic**: Compatible with a wide range of machine learning algorithms, from deep learning to traditional methods.
 - **Network communication**: Secure and efficient device communication with features like compression, network failure tolerance, and condition simulation.
 - **Trustworthiness**: Ensure the integrity of the learning process by verifying the reliability of the federation.
-- **Blockchain integration**: Support for blockchain technologies to enhance security and transparency.
 - **Security**: Implement security mechanisms to protect the learning process from adversarial attacks.
 - **Real-time monitoring**: Provides live performance metrics and visualizations during the learning process.
