Leveraging Blockchain for Identity and Authentication in IoT is good for Security
summary
Argues that IoT identity should be a hash on a distributed ledger so personal data never leaves the device; claims an app hashes ID and verifies it against a public or permissioned MDL (examples: Hyperledger, Ethereum) and can register hardware using PUF-backed device attestations. Cites scale and cost: ~20 billion devices, miners doing heavy proof-of-work with large energy use, Merkle-root storage at ~4 MB/year per chain, and pilot uses like Accenture’s smart plug.
