How to Explore IoT with Three Fun Projects

Mar 21, 2019 | by Hudson Ludvigson, Senior Software Engineer | Tags: Internet of Things

If you have been thinking about exploring concepts and projects related to IoT, but have not been able to decide where to jump in, this blog post is for you!  While there are dozens of online courses, many of those fail to provide hands on experience that can resonate and help you understand some of the concepts involved in IoT.  So with that in mind, here are three avenues you can explore IoT with varying levels of cost, time, and hardware involved.

I Have an Idea for a Mobile App, Now What?

Sep 13, 2018 | by Zach Bodensteiner, Senior Software Engineer | Tags: Internet of Things

Once you have an idea for a mobile application, it can be difficult to choose a development platform.  There seems to be a never ending list of options, with new ones added daily.  Asking around for advice can make the decision more difficult, as everyone tends to have their own preference or bias for using one platform over another.

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

Distributed Ledger Technology, Blockchain, and IoT (Part 2)

May 03, 2018 | by Hudson Ludvigson, Senior Software Engineer | Tags: Internet of Things

Author’s note: If you do a bit of internet searching you will see both permissioned and permissionless distributed ledgers referred to as blockchains.  Some will disagree and call this a travesty, others will not.  The author claims to have no idea which side is right.  For the purpose of this and related blog posts blockchains may be used to referred to as either permissioned or permissionless.

In our previous post the definition of Distributed Ledger Technology (DLT) was introduced.  In this post we will go further in understanding the various types of DLT systems that can exist.  Recall from our previous post three key factors in defining the taxonomy of DLT; how to distribute the ledger, if the ledger is public or private, and who is responsible for maintaining the integrity of the ledger (permissioned/permissionless).  The figure below provides a graphical reference for keeping those three characteristics in mind.
