“…The fusion of blockchain and machine learning is an emerging frontier, with ongoing research underscoring its promising potential. In [24], the authors presented various techniques concerning the preservation and processing of big data necessary for ML models. While this decentralized machine learning approach has advantages in terms of mitigating bias and improving fairness, the proposed solution falls short in describing the potentials for evaluating and validating the models, focusing mainly on the data stored in the blockchain.…”
