I. What is a blockchain-based security solution for IoT systems?  

Blockchain-based security solutions for IoT systems are advanced technologies that help users deal with challenges in the IoT environment, where millions of devices are connected and exchange information. Security is always a major issue in the IoT due to the dependence on traditional intermediary networks that are vulnerable to attacks.  

Thanks to blockchain, the need to rely on intermediary servers can be eliminated. This technology can distribute data across multiple network nodes, reducing the risk of attacks and creating a more secure system. Besides, blockchain also supports the authentication of IoT devices, encryption of transmitted data, and effective access management. 

A blockchain-based cybersecurity platform can secure connected devices by using digital signatures to identify and authenticate them. The devices then act as authorized participants in the blockchain network. Each authenticated device that joins a blockchain-based secure IoT network is considered a participating entity, just like in a regular blockchain network. All communications between verified participants (IoT devices) are cryptographically secured and stored in tamper-proof logs.  

Every new device added to the network is registered by assigning a unique digital ID on the Blockchain system. This platform will provide secure channels for communication between devices and all connected devices will have secure access to the host system or infrastructure simultaneously. Blockchain-based cybersecurity solutions can also leverage Software-defined perimeter (SDP) architecture and use a Zero-Trust model to make all authenticated devices invisible to attackers. This means that only authenticated devices can know about the existence of other connected devices, thereby adding a layer of security to the IoT infrastructure. 

Additionally,  blockchain-based security solutions for IoT systems can also detect and prevent tampering or data breaches. Any changes to the Blockchain chain require consensus from all participating nodes in the network. Therefore, the risk of hacking or unauthorized changes to the information can be minimized. This is especially important in sensitive IoT applications such as healthcare, smart transportation, or automated factories.
