How can Blockchain technology be used with IoT?

Technical Questions

Blockchain is not directly related to IoT. It’s a technology that – in some applications – can be used as part of an IoT solution. There are a number of different possible use cases, ranging from payment processing using cryptocurrencies to things like smart contracts, which use blockchain ledgers to exchange information securely between trading partners. Blockchain creates an unalterable record of something that has happened, which is why it is used for cryptocurrency. But in IoT, we might need an unalterable record of some sensor value and that doesn’t have to have anything to do with cryptocurrency. It’s a way for everyone to trust that the information is accurate. While not every IoT application has a need for blockchain, we have quite a bit of experience leveraging various blockchain technologies in different IoT solutions.
