A new “consensus”: The Tangle Multiverse [Part 5]

There has been a lot of discussions of the new proposal since I released the fourth part of this blog post. I have somewhat expected something like this to happen, which is the reason why I planned to have a separate part that addresses the trade offs and attack vectors.Since all of the votes are publicly known and part of the tangle, an attacker does not have too many options to mess with the system (at least not without everybody being aware).Attack vectorsThere are essentially 3 things that an attacker…

Introducing IOTA.cafe: A Public Research Forum

With the development and maturity of our technology, we noticed the need to have a forum in which everybody can follow and participate in IOTA’s research efforts.That’s why we are excited to announce the launch of IOTA.cafe, our open Research Forum.We hope that this forum will foster collaboration among team members and external researchers. And while we invite everyone to participate in the forum, please be mindful that the discussions must be exclusive to research-oriented topics.General IOTA discussions are…

A new “consensus”: The Tangle Multiverse [Part 4]

In this part of the blog post I want to finally talk about the new voting scheme that enables nodes to come to an agreement without exchanging additional votes or having to abandon transactions. Overview of the status quo Currently a transaction in IOTA can only mean one thing: It “approves” two referenced transactions, which means that it vouches for the full history of the transactions that it references up till the genesis. Since transactions can only express “total approval”, the only way to deal with “disapproval” is…

A new “consensus”: The Tangle Multiverse [Part 3]

In the last part we talked about the ledger state, which is used to track and manage conflicts by booking conflicting spends into different git-like branches. The nodes then use virtual voting to decide which one of these branches becomes part of the ledger state.Before starting to talk about the new voting scheme (finally), I want to take a last detour and talk about some fundamentals around voting based consensus mechanisms because it will help us to judge the proposed solution. Every consensus requires some form of …

Integrating physical devices with IOTA — The IOTA LED Cube

Integrating physical devices with IOTA — The IOTA LED CubeThe 11th part in a series of beginner tutorials on integrating physical devices with the IOTA protocol. Introduction This is the 11th part in a series of beginner tutorials where we explore integrating physical devices with the IOTA protocol. Its been i while since i published the last tutorial in this series as i have had to make some other priorities. This will change over the next coming months as i now have received donations from the IOTA development fund that…

A new “consensus”: The Tangle Multiverse [Part 2]

In the first part of this series of blog posts, I have described the fundamental ideas and concepts behind this new approach but all of the descriptions have been pretty philosophical and the descriptions rather vague. I now want to use the additional parts to talk about the actual algorithms and mechanisms that are required to make this approach work. PS: I have decided to break the remaining content down into several parts as well, because it just get’s too long otherwise. “Parallel reality” based ledger state The first…

A new “consensus”: The Tangle Multiverse [Part 1]

I have long thought of a way to properly present and explain the ideas behind this new approach to a broader audience. I first thought about doing it in a video to explain all the reasoning behind it but a video would maybe not be concise enough to allow people to properly look at the presented ideas and also “challenge” them. Having “something” written down will definitely help here!Usually, new consensus mechanisms get presented in form of a white-paper with lots and lots of math analysis and proper formal language but…

IOTA-based product: Lidbot

Whenever you read about the Internet of Things (IoT), it sounds like a vision from a far-away future; mini sensors talking to each other, paying for services and thereby making the world a better place. Lidbot is one of those few projects which are not only an IOTA lighthouse project with regard to the technical feasibility, but which solve real-world problems through its cutting-edge technology.Lidbot is a startup which set out to revolutionize waste disposal. CURRENT PROBLEMS FACING WASTE DISPOSALWaste…

How mesh networking ensures uninterrupted data exchange between connected devices

The full article was originally published by DXC. Read the full article here.One of the major challenges with connected devices is having a reliable network. Cell phone and standard Wi-Fi networks do not guarantee communication everywhere. Even dense urban areas have numerous “dead” cellular zones in building basements, elevators, tunnels and underpasses. Remote areas like crop fields, mines, oceans and space also pose problems.With this in mind, we designed our secure framework for cyber-physical systems to support…
