Smart contracts — self-executing contracts with the terms directly written into code — are pivotal in this integration. These contracts automate and enforce the execution of agreed-upon terms, fostering trust and transparency. Developing, testing and deploying robust smart contracts on the chosen blockchain platform will set the foundation for a secure and efficient system.

Model training and serialization

Before uploading ML models to the blockchain, they must be trained and serialized. This involves preparing the data, training the model using appropriate algorithms and converting the model into a format suitable for uploading. Serialization ensures that the model retains its structure and learned parameters, facilitating its deployment and utilization on the blockchain.

The process of transforming a trained machine learning model into a format that can be conveniently stored, communicated or loaded for subsequent use is known as serialization. By storing the model’s architecture, parameters and weights in a file or memory, it can be loaded and used again without needing to be trained. Serialization is essential for integrating machine learning models into a variety of contexts and applications.

Uploading models to the blockchain

Once serialized, the ML models are ready to be uploaded to the blockchain. This step requires careful verification and validation to ensure the model’s integrity and functionality. Uploading models to the blockchain encapsulates them in a secure and transparent environment, paving the way for enhanced accessibility.

Implementing model updates

Machine learning models necessitate regular updates to maintain their accuracy and relevance. Implementing these updates on the blockchain is crucial and must be carried out meticulously to preserve the model’s integrity while keeping the user community informed and engaged.
