Tangle — the missing link for IoT and Web 3.0

To understand what Tangle is and why we need it, we need to know two concepts beforehand. They are Distributed Ledgers and Blockchains. For those of you who are aware of what distributed ledgers and Blockchains are, you can skip the next two sections, others, follow on and you would find a brief introduction to both of these concepts. Distributed Ledgers Ledgers Anybody who owns a bank account would be aware of ledgers. A ledger is a book or a computer file which keeps track of the economic transactions. Right now, these…

AWS Lambda and IOTA FTW!

A little while back, I worked on little demo of performing IOTA Proof of Work on AWS Lambda Functions.I never got around to writing a tutorial, so I thought I’d get back to turning it into a proper npm package, and making an easy-to-deploy environment. Why? Why would we want to perform the PoW in AWS Lambda?Well for a number of reasons:You don’t want to host your own IOTA Full Node, but you can’t or don’t want to perform PoW on your local device. You want an easy way to provision basic resources for a…

IOTA experienced as a real idiot

and the CAP-Theorem explained for real idiots IOTA is not your normal everyday bitcoin source code forked blockchain. IOTA is more like that crazy nerd guy from school, really different and you don’t know if he will be a Bill Gates later or just some fat basement dweller. In the world of blockchains IOTA is so different that it isn’t even a blockchain. Wait a second, it is not a blockchain? No. It is a directed acyclic graph. Or in short and not less confusing DAG. We should always bear in mind that we are real idiots and…

36 minutes in the life of a future autonomous electric vehicle

From Arduino to Tangle

A guide to Johnny Five, Arduino and IOTA’s MAM In my previous post, we started looking into IOTA’s Masked Authenticated Messaging (MAM) module, and how to apply it to a simple pub/sub application.In this post, we’re going to explore a simple case of getting MAM interfacing with an Arduino, using Johnny Five. This post was inspired by @Chrislaive on Discord, with his great example of MAM and Arduino, which you can find here. Thanks Chris! Set Up Aside from the Gists you see below, you can see all of the code for this…

In-depth explanation of how IOTA making a transaction

Our transaction scenario Person A have a seed A_SECRET_SEED that contain 100i in 4 different address relate to this seed: seed: A_SECRET_SEED address: AAAAAA……AAA, balance: 10 address: BBBBBB……BBB, balance: 5 address: CCCCCC……CCC, balance: 25 address: DDDDD……DDD, balance: 60 address: EEEEEE……EEE, balance: 0 Person B have a seed B_SECRET_SEED that contain 0i in its address: seed: B_SECRET_SEED address: QQQQQQ……QQQ, balance: 0 address: QQQQQQ……VVV, balance: 0 Today, Person A want to send 80i to Person B’s address…

Dipping our toes into MAM

Let’s learn about IOTA’s MAM Module together As I’ve been following along with IOTA for the last year or so, I’ve been working on and off of a few projects here and there. Of late, I’ve been wanting to get some experience working with MAM and Flash Channels. Since I couldn’t find too many guides out there, I figured why not write one? So this is a learning experience for both of us. If you see flaws in my code or logic etc, please let me know — I don’t claim to be an expert, just another guy trying to figure out how to…

IOTA Tangle Analysis

Analyzing Addresses, Full Nodes, Services and Community In April In April we decided to start taking some data points on how the IOTA network was growing and how it’s community was providing value to the network. We also need to be able to model future growth for market sustainability. Questions are truly answered by following the scientific method. The Scientific Method. Source: Wikipedia We wanted to know if the IOTA community is using their IOTA for online shopping. We recorded the PayIOTA plugin that is available for…

What is IOTA and its upcoming module Qubic

What is IOTA? IOTA is a revolutionary new, next generation public distributed ledger that utilizes a novel invention, called a “Tangle”, at its core. The Tangle is a new data structure based on a Directed Acyclic Graph. As such it has no Blocks, no Chain and also no Miners. Because of this radical new architecture, things in IOTA work quite differently compared to other Blockchains.The problem IOTA solves Anyone with a bank account is familiar with the concept of a ledger, containing records of their debits and…
