In the fourth episode of Untangled we are exploring the realm of indoor mapping and localisation. Mapping and localisation has reached incredible levels of accuracy over the years, but indoor mapping is lacking far behind. To find out why that is and how it can be improved through the use of distributed ledger technologies, we are talking to Georgios Pipelidis, co-founder of NavIndo, a Munich-based start-up dedicated to indoor mapping and localisation. We are also speaking to Bhaskar Krishnamachari, director of USC…

As the New Year begins it is a great time to plan the future of Entangled. First, what is Entangled? Entangled is a monorepo for all things Tangle that add functionality for operating IOTA in C/C++. If you would like to keep up to date with the project, the repo can be found and starred here: https://github.com/iotaledger/entangled Why make IOTA C-based? The primary reason is our focus on the Internet of Things (IoT). Many of these small form-factor devices run on very efficient and small program sizes which are…

After the Climate Change Conference in Paris has set 2015 global Carbon emissions targets and around 200 countries around the world have come out in favor of it, it’s time to draw a small conclusion. This was published by the IPCC on 8th of November 2018 with a special report. This article describes the consequences of 1.5 degrees of warming and what needs to be done to keep the temperature from increasing even further. Over 6,000 studies were evaluated. The result is sobering: currently the world is headed for a…

We want to help with enterprise mass adoption… Connect your IoT device to the Tangle, explore fee-less micro transactions and the use of MAM, support the evergrowing Peer-to-Peer IOTA network. Baby steps into the world of IOTA, soon-to-be the backbone of the IoT. Deploy your own IOTA Full Node in Azure If you are a developer or wish to pursue a more in-depth understanding of IOTA’s Tangle, then we advise you to join the IOTA Discord #fullnodes channel. You will find there an extremely supportive dev…

This is a follow-up (Week #2 Update) on the series of The Tangle Bay, the IOTA listing platform launched on January 4, 2019. As we continue to follow IOTA, we can start to see the bigger picture being drawn at the end of the tunnel. And the tunnel represents the current market state, the FUD and the race against the next “great project” that will change the world for good. In this article, I hope to explain why TTB is the Ultimate IOTA Listing Platform, so please bear with me. In order to understand the full…

This is the first of resurrected regular updates from the Trinity team. Every two weeks, we will be posting a brief overview of the team’s recent focus, together with any ideas and longer-term plans surrounding the project. Here’s a refresh on where we currently stand. Trinity was released to mobile beta in late May and desktop beta in late August 2018. The codebase was open sourced with the release of desktop beta. Since then we have had an overwhelming response, with 10,000 active iOS users, 20,000 installs on active…

Listing Partner of Tangle Universe in nearly all continents Since one week the project “Tangle Universe” is now released as Alpha Version and we would like to give you a short update https://tangle.publiciota.com/. Thanks for the constructive and positive feedback from the IOTA community and also from the non-community. To recap, this project seeks to provide transparency about Tangle’s services, projects and friends. Tangle Universe is a database project designed to facilitate the search for suitable services. The aim is…

TangleID Demo Site This sample web service is designed to illustrate how a certification website issues verifiable claims to the identity holders with TangleID. The scenario we choose is the certification process and the roles contain: Student: As a holder, a student is able to arrange his or her personal data and claims with verified carriers. College: As an issuer, a college can issue verifiable claims to the holders after verifying students' identity. Flow Step1: Register the Decentralized…

Rate control in distributed ledgers In most networks, there are circumstances where the incoming traffic load is larger than what the network can handle. If nothing is done to restrict the entrance of traffic, bottlenecks can slow down the entire network. Additionally, the buffer space at some nodes may be exhausted, leading to discarding some of the packets. Similar to a highway traffic jam, as the offered load increases, the actual network throughput decreases while packet delay becomes excessive. Therefore a mechanism to…

Lightest Masked Authenticated Messaging protocol for IOTA Inspired by MAM Lite protocol, a light-weight alternative to MAM streams in IOTA, written by Samuel Rufinatscha I decided to re-implement it in Python. Doing so I stumbled into a few limitations, originated from RSA signature scheme used in MAML and therefore I opted to switch to another signature scheme, Ed25519 (the one that NANO uses). It has much shorter public keys and signatures and thus provides several advantages, that will be discussed later. As the result…

Ledger recently announced the launch of the IOTA compatible Ledger Nano X. This new product is built around a new hardware architecture, while taking advantage of our versatile security Operating System BOLOS. The Ledger Nano X features Bluetooth Low Energy (BLE) connectivity enabling it to be used with Android or iOS devices without the need of a cable. While this feature greatly improves the user experience, it raised some concerns about the security of the wireless connection. We would like to address these. In…
