Distributed Ledger Technology, Blockchain, and IoT (Part 3)

Jun 14, 2018 | by Hudson Ludvigson, Senior Software Engineer | Tags: Internet of Things

As has been mentioned in past blog posts, there are security concerns with IoT systems.  When discussing distributed ledger technology (DLT) we investigated how a blockchain approach could address the security concerns, but introduces system demands in terms of memory and computing power that do not appear practical for many of the simple IoT devices on the market today. Enter the permissioned blockchain; a network where only specific nodes are required to maintain the transaction ledger and determine which transactions are allowed.  This addresses the problem with strict centralized control discussed in the first blog post in this series and the issue of memory demands discussed with a completely decentralized model in the second blog post
