Although blockchain technology has been tainted by scammers, the core idea of distributed consensus is relevant for certain edge applications. This episode of Utilizing Edge focuses on practical application of blockchain technology in edge and IoT, featuring Jason Benedicic, Alastair Cooke, and Stephen Foskett. Two key concepts in blockchain are the distributed ledger and consensus approach. There is a lot of work being done to apply blockchain in medical, finance, IoT, and proof of provenance. Although many applications can rely on authority or quorum, larger and more heterogeneous applications might benefit from consensus instead. The other aspect of blockchain, chain of custody and immutability of data, is potentially relevant in preventing supply chain attacks and dealing with transient devices. It’s important to remember that many of the things that have put people off blockchain, from financialization to public exposure of transactions, are not necessarily required in all blockchains.
