What Is IOTA? How Does It Work?

The IoT ecosystem has become an integral part of today's technologically advanced world, where billions of devices exchange data and information over the internet. IOTA is a unique project that aims to facilitate transactions in the IoT ecosystem by creating real interaction between the human and machine worlds.

To better understand the IOTA network, you can read this guide to understand what IOTA is, how it works and its main benefits.

What is IOTA?

IOTA is an open-source decentralized distributed ledger designed to facilitate data exchange between IoT devices. Particular attention is paid to the Internet of Things and the evolving relationship between human and machine economies. A unique feature of IOTA is that instead of blockchain technology, it uses a direct acyclic graph (DAG) called Tangle to process transactions. In this way, the network offers faster, more energy-efficient and sensorless data exchange between IoT components and with fewer infrastructure requirements.

IOTA was founded in 2015 by David Sönstebø, Sergey Ivanceglo, Dominik Shiner and Dr. J. Founded by co-founder Sergey Popov as an IoT solution with a distinctive Tangle system.

Understanding IOTA: How does it work?

Unlike cryptocurrencies and other decentralized applications, IOTA does not rely on traditional blockchain structures. Instead, it relies on Tangle, another type of technology that represents a breakthrough in blockchain and is ideal for the IoT ecosystem. This innovative framework allows IOTA to overcome the cost and scalability issues associated with standard blockchain networks like Bitcoin.

Main features of The Tangle – The technology behind IOTA

From a technological point of view, Tangle is IOTA's DAG consensus algorithm, which requires users to confirm two transactions in order to transfer their transaction . Most importantly, Tangle technology uses no miners, validators or blocks, reducing the resources and costs required in blockchain systems.

First, since IOTA uses a binary protocol that includes a fast probability algorithm including consensus and proof-of-work for speed control, no miners are required. Because IOTA does not use PoW to reach consensus, the total energy required for each transaction is minimal. Of course, the extremely low power limit makes miners unsuitable to serve the IOTA network.

Second, the Tangle doesn't suffer from the "transaction queue" problem during network loading, as each transaction is routed separately while it has to process two more transactions. In theory, this process makes the IOTA network very scalable. Also note that these asynchronous operations work on the principle that any faulty communication will be automatically interrupted and discarded as the system grows.

In addition, the Tangle protocol is enhanced with quantum security features that include hash-based signatures, as opposed to the elliptic curve signature scheme used by Bitcoin. These signatures make it easier and faster for the IOTA network to sign and verify transactions.

The IOTA framework is truly at the heart of the Internet of Things as it facilitates the exchange of data between machines and devices on the Internet, reducing network congestion issues and the need for human intervention. The platform is currently working on the IOTA 2.0 update to fix existing security issues and further decentralize the whole system.

IOTA Native Coin - MIOTA

IOTA's local currency, MIOTA, was created at network creation with a maximum of 2,779,530,283 tokens. All pre-mined tokens (maximum supply) are released and immediately distributed to investors , unlike regular cryptocurrencies that are mined during transactions .

5% of these tokens were distributed to promote the development of IOTA and the creation of the IOTA Foundation. IOTA is currently ranked 55th by CoinMarketCap with a total market cap of around $860 million.

The main advantages of IOTA

The value of IOTA comes from the variety of benefits it offers that are not available in most blockchain projects.

First, IOTA is a free and open-source data exchange network that operates without fees for network participants. For example, users don't have to pay gas fees for mining rewards like Ethereum or Bitcoin or other PoW blockchains.
IOTA's scalability sets it apart from other traditional low-speed networks. It can process more than 1000 transactions per second compared to traditional blockchains like Bitcoin and Ethereum.
IOTA is considered an energy-efficient network because it does not use heavy mining equipment or other energy-intensive products.
IOTA has a wide range of use cases and has attracted the attention of many tech giants such as Microsoft and Tesla. For example, IOTA can be used for microtransactions like parking fees and smart charging in the electric car industry. Overall, IOTA is effectively benefiting from the growth of the digital industry and the expansion of the IoT space.

Concerns about IOTA

Although IOTA contains many positive aspects, there are gaps in its infrastructure, mainly on the technical side. According to some experts, there are several issues with IOTA's ability to overcome scalability issues with DAGs. Also, this network is very new and fresh at the moment.

Another criticism of IOTA relates to its “clearing nodes”, which could endanger the decentralization of the IOTA ecosystem. A coordinator is a central client that transmits signed messages called milestones that nodes trust to confirm transactions. Because the coordinator has a high level of control over all operations, they can become a single point of failure. In 2020, hackers used a loophole in the official IOTA wallet to steal millions, after which the IOTA Foundation had to stop “coordinating” for a while.

Critics also point out that coordinators slow down the network because parallel processing is not possible in coordinator-based architectures. Given these concerns, IOTA intends to remove the coordinator in the upcoming IOTA 2.0 update.

One last thought

IOTA has promising potential and a positive outlook for the future due to its connection to IoT technology and unique application of tamper-proof transaction processing. The project could play an important role in shaping a digital future where ecosystems of machines and humans can communicate seamlessly without complex blockchain systems. While the project is currently drawing some criticism, it's still a work in progress and an upcoming update could fill those gaps.
