Dispelling the Hype: When (not) to useBlockchain in IIoTWhen to use blockchain technology You need a shared database You need a database with multiple writers You have a situation with multiple non-trusting writers You do not want to rely on a trusted intermediary You desire interaction between transactions in the databaseAvoid using block chain technology If you lack any of the five above conditions “If trust and robustness aren’t an issue, there’s nothing ablockchain can do that a regular database cannot”, GideonGreenspan, CEO of Coin Sciences Ltd.
