What we have to say, what you want us to hear.

That’s how our blog works. It’s interactive. Let’s learn together.

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.

Distributed Ledger Technology, Blockchain, and IoT (Part 1)

Mar 29, 2018 | by Hudson Ludvigson, Senior Software Engineer | Tags: Internet of Things

You just hit buzzword bingo by reading the title, congrats!  Over this and several follow up blog posts we’ll explore the idea of distributed ledger technology (DLT), how it is related to blockchain technology, how DLT could be leveraged by IoT applications, and some of the challenges facing using DLT in the IoT space.  For starters we’ll focus in on what DLT is, which will lead to our discussion about blockchain.  Then in future posts, we’ll cover how this technology can be leveraged by IoT applications as well as some of the potential challenges.  While DLT and blockchain are often used interchangeably, for the purposes of our discussion we will treat them as two distinct items, though they are closely related.

IoT Platforms and Economics

Feb 15, 2018 | by Hudson Ludvigson, Senior Software Engineer | Tags: Internet of Things

If you were to ask most people to name some popular social media platforms, you would likely get a quick response of Facebook, YouTube, Twitter, or MySpace (just kidding on that last one).  Ask that same person to name some popular IoT platforms and prepare for a deer in headlights look.  Even if a person has knowledge about the IoT space, they likely do not know what the market is offering in terms of platforms.  That’s in large part because the market is still very much in the early stages.

Best Practices - Treat Your SDK Like You Treat Your Code

Jan 18, 2018 | by Hudson Ludvigson, Senior Software Engineer | Tags: Internet of Things

Developers often work individually or in a larger team to produce products for a variety of consumers.  Sometimes it’s a web app, a mobile app, or perhaps software for an overall system that includes some hardware.  When developers are creating something that will be out on the marketplace they know it will reflect on them or their company, and have an impact on whether or not trust is built in the marketplace.  In this scenario, documentation in the form of help menus or instruction manuals may be extensive to make sure the user experience is ideal and that any issues or concerns raised are promptly addressed.  In contrast to this, when it comes to working with other developers through documentation or direct support, completeness and attention to detail can often be lacking.
