Abstract
The term "Internet of Things" (IoT) refers to a situation in which intelligent things are linked to a network or the internet. IoT objects have become more prevalent over the past several years in many industries, and fields, and are now used in all facets of our life. The privacy of data is a crucial problem as the number of devices rises. Researchers in this discipline have employed a variety of strategies to address this issue. Regrettably, there is less accountability, data protection, and traceability with these solutions. In this study, a blockchain-based network architecture for accountability, privacy, and traceability is designed (TDA). Blockchain technologies are referred to as a distributed ledger of transaction records, which time-stamped information about a transaction's lifetime. Persistence, decentralization, and audibility are three of blockchain's key characteristics. The budget is reduced and efficiency is increased thanks to these characteristics. This study also discusses the performance of the suggested architecture in order to strengthen the TDA architecture.
