IOTA: MAM Eloquently Explained

MAM, Masked Authenticated Message, is one of the most remarkable features of IOTA. Let us speculate the world full of small IoT devices, where their small jobs, flow of microscopic data, and nano-payments come and go all over the globe. IOTA, whose goal is to become the very fundamental layer of coming society, is the most provident project of the time that challenges looming paradigm shift. And MAM is its core driving force, which distinguishes IOTA from other distributed ledger by making data flow and transactions much…

IOTA: Signature And Validation

Address generation First of all, create Private Key from Seed.// length = security (1: light client, 2: wallet default, 3: exchange level) var key = function(seed, index, length) { ... return key; // private key }have your Private Key ready, whose length = security * 2187 . Private Key is partitioned into L distinct segments, where L = security * 27. So, each segment would be 81. Hash all segments as a whole. The product is called digest. Hash digest once. The product is called address.Seed ->…

IOTA: Multisig Explained

Multisig Transferring large amount of money, especially the ones that involve exchange level of security, it is worrisome to have only one seed be solely responsible for the transfers. Multisignature is used to send secure transfers by asking for several co-signers. Even though multisig transfers are created in a way different than that of ordinary individual transfers, when attached to tangle, it appears to be no different, and people cannot distinguish multisig-ly attached transfer(=bundle) from others. Thanks tangle! You…

Semantics, headlines that sell and why The Next Web did not find a vulnerability in IOTA

TL;DR In a nutshell, somebody with absolutely no track record in the cryptocurrency space has deliberately created transactions which are insecure by design. He then forged his own, insecure transactions. The Next Web frames this as research to capitalize on clicks and does a huge disservice to its readers and the community at large. This could have been an article about journalistic integrity. Or about the growing trend to publish boldly exaggerated headlines to capture the ever decreasing attention span of an Internet…

Limiting the overlap of IOTA signatures when double spending

IOTA uses Winternitz one-time signatures to sign off on spending iotas from an address. The nature of these signatures is such that during the signing process 50% of the private key to that address is exposed. This is normally no problem, because the addresses are supposed to be used only once. But there’s the rub. It has been shown time and again that it is possible to get into a situation where you have to spend again from the same address. For example when withdrawing from an exchange to the same address multiple…

IOTA: supply chain as a use case

IOTA’s advantages over other blockchain/Distributed Ledger Technologies (DLTs) can be summarized as being fast, free and scalable. Besides autonomous driven (electric) cars supply chains are among the use cases which the Iota Foundation is focusing on at the moment; this is why Dominik Schiener, Co-founder of IOTA, will also talk about this in the context of the Bosch Connected World Expo. But what is it after all?Wikipedia says: A supply chain is a system of organizations, people, activities, information, and resources…

Iota: Worries and Solutions in Conversation.

Here I am reading your thoughts and ask your Questions to myself on how to get into Iota. You:Hi, may I briefly explain my dilemma? I want to buy iota and keep it longer. But there are many things that make me unsure.CryptoViking:Yes, sure. Go for it.You:I face the problem that I have no sense of how to keep Iota in the long term. Should I leave the iota on bitfinex or is this PC wallet safe? Can Iotas be lost on these “old seed-new seed” issues,updates or new releases?CryptoViking:Okay, so in the first place…

Extending the Tangle network to a distributed cloud

Some thoughts on the technical and social architecture of a machine-economy.What is needed for the future to happen? The idea of data-markets backed by digital currencies has been floating around for some time now. This article talks about the software infrastructure needed to build such data-markets and what such markets might look like using the IOTA protocol as the hypothetical “currency” for data-exchange.Throughout this article we can theorize IOTA as a handshake-protocol and as an immutable ledger of…

Solving the IOTA donations problem by using IOTA cheques

#iotapower The donation problemFor the longest time one of the problems with IOTA has been the impossibility of having a secure and fixed reusable donation address. This is entirely due to the single-signing nature of IOTA addresses. You cannot simply post an IOTA address and have people send funds there, because once you spend from such an address that address should no longer be used. Of course you cannot enforce the closing of the address, because people may have bookmarked it and they can still send funds to it after…

Blockchain vs. DAG: Behind the Battle for the Backbone of the Internet of Things — A History

Nothing can be more logical — we work so hard to put food on our table, to clothe our children, to carefully craft and build our lives and create a sense of comfort and security — the last thing we want to do is jeopardize that or put ourselves in any situation that might challenge or begin to break down those carefully crafted and fortified walls.But unfortunately, like anything (and this is the tough part for us to understand or even accept, and we’re seeing examples in every segment of society from politics to business…

IOTA: The case of Decentralized Digital Identity

The other day @BongInma1 pointed my interest towards one of IOTA’s main fields of operation besides Internet of Things (IoT; although the two are obviously linked): Decentralized Digital Identity. One has to distinguish between Identity of Things (which I have touched upon in my previous article) and Decentralized IDs (DID, mainly human beings’ identities). I shall first explain what this is actually about and second what IOTA has to do with it. 1. Decentralized Identity — what is it after all? I will follow Outlier…

The state of third party IOTA wallets

The IOTA ecosystem is one of the most vibrant I’ve ever been part of. Lots of brilliant developers are working on exciting projects to explore the opportunities of the Tangle and the level of innovation is astonishing at times. If you manage to ignore the FUD — which unfortunately seems to go along with all-things-crypto these days — actively engaging with this community is a technology enthusiast’s dream come true. There’s one aspect, however, that causes sort of a dilemma: How to deal with third party wallets? Wallets…
