Analysis: Three Things May Limit Blockchain Use on the Internet of Things

This article examines the potential and limitations of applying blockchain technologies (e.g., Bitcoin, Ethereum, IOTA, Hyperledger) to Internet of Things deployments, highlighting advantages such as decentralized identity and immutable ledgers but focusing on practical hurdles — concentrated mining power, replicated storage needs, slow block times, and key-management risks — and noting research directions (light clients, pruning, Proof-of-Stake) and a multi-year timeline for mainstream IoT adoption.
