The cable operator industry is poised to further embrace blockchain technology this year. Steve Goeringer, principal security architect at cable consortium CableLabs, wrote in a blog on Thursday that this is the "year that cable starts to integrate blockchain solutions, but it will be quiet and subtle."  

Blockchain, which was developed for Bitcoin, is a digitized, distributed ledger of transactions, which can be particularly relevant to IoT security, according to Goeringer. Goeringer wrote that blockchain was transformational because transactions were recorded statements of fact that could be used by businesses, regulators, operators and their customers.
