Since most IoT networks are generally configured, data is not considered worthy until it is checked and controlled. Through the centralized security port, an attacker can access the security servers and the entire IoT. The main problem with IoT devices is that a single compromised device can interfere with a network as a whole. These compromised devices could be used improperly as bots for Distributed Denial-of-Service (DdoS) deployment. IoT devices are not smart enough to identify if the received data is genuine or unusual. These are subject to higher targets for security attacks, and yet blockchain technology can detect anomalies and prevent IoT devices from coming from such threats.
A new blockchain technology to improve IoT is still under development. IBM recently won a patent for self-service networked devices that is part of its self-contained decentralized peer-to-peer telemetry environment (ADEPT), assigned by the U.S. Patent And Trademark Office (USPTO). This technology works by storing data in a distributed ledger that is immutable and can not be changed at any cost and ensures the credibility of data within the network. IBM is diversifying its involvement in blockchain-related fields, which could leverage automation to address privacy and security issues for drones.
The decentralized blockchain approach enhances trust between IoT devices, ensures the tracking of all devices and creates a resilient system less subject to security threats that remain safe from interception. Self-service devices can diagnose and automate problems such as predicting equipment failure and anticipating service needs, thus increasing the efficiency of a decentralized system.
The IoT distribution enabled for Blockchain can improve the integrity and the integrity of the system, making it easier to register and validate the device on the network. The implementation of the blockchain model in an IoT network can solve a series of real digital business problems such as analytical model tracking, secure software updates and automated payments. The application of blockchain technology to IoT is not a cure-all. Its current operating performance and scalability limits are incompatible with many IoT functions. A new version of the blockchain platform involved in an IoT deployment is needed with features that can extend beyond today's regular models. What comes next is a hybrid or polyglot architecture with custom frameworks that use blockchains differently on IoT. Blockchain is not at all an answer to all that afflicts IoT; instead, it can play a crucial role in solving some serious problems. It's not that blockchain do not save IoT, but it can really improve the IoT.
