effectiveness of the projected classifiers which are T-KNN and I-KNN. After passing

the dataset into the classifiers, the classification of the dataset was produced and these

were evaluated using the confusion matrix performance analysis.

The proposed system architecture combining ML, Blockchain, and IoT systems

was showed in Fig. 1. It was deduced that Blockchain technology is used to secure

the system by authenticating the users of the system using their IDs. Blockchain

technology is also used to secure smart applications and IoT networks.

Classification Evaluation

A confusion matrix was employed for the performance evaluation of the system

executed. Accuracy, detection rate, and false-positive rate are the matrices used

for the evaluation of the system. It can be deduced that a classifier effectively and
