Federated Learning (FL) is a type of distributed Deep Learning framework, in which the model is trained locally on each device and the trained gradients are sent to a central server which aggregates them and creates a global model. This helps ensure the data privacy of the user as the data never leaves the local device. However, a major concern in Federated Learning is ensuring the data quality of trained data. A model trained on poor quality data can have a major impact on its accuracy. In this
proposal, we propose a decentralized approach using blockchain to counter this issue. We use a set of miners in blockchain who act as validators for data. They validate the data quality, check for correct labels, and ensure the model is protected from data poisoning attacks. Both the validators and trainers are awarded for their contribution using smart contracts. We also devise a point system, where a trainer will be awarded more points if they train with good quality data and points will be reduced for poor quality data.
