Frequently Asked Questions

Why combine blockchain with IoT?

Blockchain can give IoT devices tamper-evident logs, decentralized identity and automated payments between machines, without relying on a single central server.

What are the main challenges?

Constrained devices have limited storage, power and bandwidth, and many blockchains have limited throughput and fees, so designs usually keep raw data off-chain and store hashes or proofs on-chain.

What are typical use cases?

Supply chain traceability, device identity and firmware integrity, decentralized wireless networks such as Helium, and machine-to-machine micropayments.

Which blockchains are used for IoT?

IOTA, IoTeX, VeChain, peaq and Helium target IoT specifically, while enterprises often use Hyperledger Fabric or Ethereum-based networks with IoT platforms such as AWS IoT or Azure IoT Hub.

Why were some older articles removed?

A few older items were dropped because they were dated or no longer reachable, including a vehicle-rental token article and a PDF that blocks access.
