However, the large spatial distribution of edge server deployments raises security issues such as access control, privacy, authentication, and intrusion detection. Blockchain, with its distributed, decentralized, immutable, shared transaction ledger, has the potential to address the security and privacy issues associated with edge computing.
To cyber attacks. Millions of connected devices generate huge amounts of data, which is then transmitted over the Internet. Blockchain consensus algorithms confirm each transaction and can ensure that the data transmitted by IoT devices is verified and valid and has not been tampered with during transport.
However, mining and consensus processes costa rica mobile database resource-intensive, and IoT devices, being resource-constrained, are poorly suited to such computational load. Offloading processing to the cloud is not an option — the obvious reason is latency. Edge computing is one solution to offload IoT nodes from intensive computational tasks.
Together with blockchain, edge computing appears to be part of the perfect combination for creating a secure, scalable, and distributed platform for IoT. While blockchain helps address the security issues inherent in edge computing and IoT, edge computing provides the low-latency, distributed, scalable network that IoT applications rely on.
