A beginner's guide to IOTA, the open-source distributed ledger and cryptocurrency designed to power the Internet of things economy.
IOTA is a cryptocurrency that aims to provide a fast, secure, and fee-less way of sending and receiving transactions on the internet of things (IoT) network.
Unlike traditional blockchain-based cryptocurrencies, IOTA uses a technology called Tangle, which allows users to make free transactions.
All without the need for miners to validate them at all.
IOTA is a promising cryptocurrency that offers several benefits over traditional blockchain-based cryptocurrencies.
As you’ll discover in our IOTA guide below, its Tangle technology allows for fast, free and more efficient transactions, making it something different to the sometimes mundane, similar projects we continue to see churned out.
With a focus on the internet of things and rapid scalability, IOTA certainly has potential to change the game.
Introduction to IOTA
IOTA was developed by David Sønstebø, Sergey Ivancheglo, Dominik Schiener, and Dr. Serguei Popov in 2015.
The team's goal was to create a cryptocurrency that could provide a fast, secure and fee-less way of transacting on the internet of things (IoT) network.
IOTA has a total supply of 2.78 billion tokens, with no new tokens to be minted in the future.
As we briefly introduced above, one of the key reasons why IOTA has the potential to be a game-changer in the cryptocurrency space is its Tangle technology.
Unlike traditional blockchain-based cryptocurrencies, which require miners to validate transactions, IOTA uses a decentralised and trustless system where users validate each other's transactions.
This means that IOTA transactions can be processed faster and more efficiently, with no transaction fees.
The Tangle technology also allows IOTA to be more scalable than other cryptocurrencies.
As the network grows and more users join, transactions can be processed more quickly and efficiently.
Making it an ideal cryptocurrency for the internet of things, where large volumes of transactions are required.
Having already attracted interest from companies and organisations in various industries, IOTA is a point of difference worth exploring in any crypto portfolio
Is IOTA and MIOTA the same?
IOTA and MIOTA both refer to the same cryptocurrency.
In saying that however, they’re used in different contexts to represent different units of measurement.
IOTA is the name of the cryptocurrency itself and is represented by the symbol "IOTA".
It is the smallest unit of IOTA that can be transacted on the network and is equivalent to one quintillionth (10^-18) of an IOTA.
But due to the small value of 1 IOTA, it is usually quoted in MIOTA rather than IOTA when buying or selling on exchanges.
Therefore, while IOTA is the actual name of the cryptocurrency, MIOTA is a more practical unit of measurement for buying, selling, and trading on exchanges.
How many IOTA are in a MIOTA?
MIOTA stands for Mega IOTA and is the most commonly used unit of measurement for IOTA.
1 MIOTA is equivalent to one million (10^6) IOTA.
How does IOTA work?
IOTA's unique technology is based on a directed acyclic graph (DAG) called the Tangle, which is used to validate and confirm transactions on the network.
Unlike traditional blockchain-based cryptocurrencies, IOTA does not rely on miners to validate transactions.
Instead, each user who wants to make a transaction must validate two previous transactions, creating a decentralised and trustless system.
This consensus mechanism, called "coordicide," removes the need for miners, making transactions faster and more efficient.
Additionally, this consensus mechanism means that IOTA has no transaction fees, making it an attractive option for micropayments and transactions where low fees are critical.
The Tangle is designed to be scalable, meaning that as more users join the network, transactions can be processed more quickly and efficiently.
This makes IOTA an ideal cryptocurrency for the internet of things (IoT) network, where devices are constantly communicating and exchanging data.
IOTA can facilitate M2M (machine-to-machine) transactions and enable the exchange of data in a secure and decentralised way.
IOTA's focus on the IoT network means that it has the potential to revolutionise several industries.
For example, in supply chain management, IOTA can be used to track and verify products' authenticity, ensuring that they are not counterfeit or tampered with.
In healthcare, IOTA can be used to securely share patient data between hospitals and medical professionals, improving patient care and reducing costs.
The possibilities for IOTA across the ever expanding internet of things, are truly endless.
What is IOTA crypto (MIOTA) used for?
The IOTA cryptocurrency itself has several use cases, ranging from micropayments to data exchange in the IoT network.
One of the most significant advantages of IOTA is its scalability, which makes it ideal for large volumes of transactions and data exchange.
Below are some of the main uses of the IOTA (MIOTA) coin.
Micropayments
IOTA's feeless transactions make it an attractive option for micropayments, which are transactions of small amounts of money.
IOTA can be used to make payments for digital content, such as articles, music, and videos.
Data exchange
IOTA's Tangle technology enables secure data exchange, making it an ideal cryptocurrency for the IoT network.
The IoT network requires the exchange of large amounts of data between devices and IOTA can facilitate this exchange in a secure and efficient way.
Supply chain management
IOTA can be used to track and verify products' authenticity in supply chain management.
By using IOTA, manufacturers and retailers can ensure that their products are not counterfeit or tampered with.
Healthcare
IOTA can be used to securely share patient data between hospitals and medical professionals.
This can improve patient care and reduce costs, as medical professionals can access patient data in real-time that lead to quicker diagnoses and treatments.
Decentralised applications
IOTA's Tangle technology can be used to create decentralised applications (dApps) that run on the IOTA network.
These dApps can facilitate micropayments, data exchange and other use cases, making IOTA a versatile cryptocurrency.
As you can see from this section of our guide to IOTA, the coin has several use cases, across multiple fields.
Its scalability and feeless transactions make it an attractive option for large volumes of transactions, while its Tangle technology enables secure and efficient data exchange.
Is IOTA centralised? - The dreaded coordinator node
One of the most significant debates surrounding IOTA is whether it is centralised.
The presence of the Coordinator node has been a major point of contention among the cryptocurrency community.
The Coordinator node is a centralised entity that was put in place to protect the network from certain types of attacks.
It works by validating transactions and ensuring that no double-spending occurs.
However, its existence has led many to question the decentralisation of the network.
In the past, there have been instances where the Coordinator node has been stopped, leading to concerns about the security of the network.
For example, as you’re going to see in the next section of this guide, the Coordinator node was shut down due to a vulnerability in its software.
Ultimately causing the entire IOTA network to come to a halt.
However, the IOTA Foundation has been working to decentralise the network and remove the Coordinator node altogether.
They have been developing a new consensus mechanism called Coordicide, which aims to eliminate the need for the Coordinator node.
The Coordicide project has been in development for several years, and the IOTA Foundation has made significant progress in achieving its goals.
They have already released several components of Coordicide, including a new consensus mechanism called Fast Probabilistic Consensus (FPC).
We’ll have to wait and see how it pans out, but the development of Coordicide is a significant step forward and once fully implemented, it could actually make IOTA one of the most decentralised cryptocurrencies in the market.
Was IOTA halted?
On February 12th, 2020, the IOTA Foundation announced that it had shut down its Coordinator node after receiving reports that hackers were stealing funds from user wallets.
As we just discussed, the Coordinator node is a centralised entity that was put in place to protect the network from certain types of attacks and validate transactions.
However, the shutdown of the Coordinator node had the side-effect of effectively shutting down the entire IOTA cryptocurrency network.
The hack in question exploited a vulnerability in IOTA's Trinity wallet, which allowed the attacker to steal funds from several user accounts.
The IOTA Foundation reacted quickly by shutting everything down to prevent further attacks and mitigate the damage.
The decision to shut down the network was not taken lightly and it caused significant disruption to the IOTA community.
The argument is that it was a necessary step to protect the funds of IOTA users and prevent further attacks.
In the aftermath of the hack, the IOTA Foundation took steps to address the vulnerability in its Trinity wallet and enhance the security of its network.
They also worked on improving communication with the community and addressing concerns about the centralisation of the network.
To put it lightly, the halt of IOTA in February 2020 was a challenging time for the project and its community.
But the IOTA Foundation's quick response to the hack and their efforts to improve the security of the network demonstrate their commitment to protecting the interests of IOTA users and building resiliency in the project.
IOTA pros and cons
As with any cryptocurrency, IOTA has its advantages and disadvantages.
In this section of our guide to IOTA, we'll take a look at some of the major pros and cons.
Pros of IOTA
- Feeless Transactions: One of the most significant advantages of IOTA is its feeless transactions, making it ideal for micropayments and transactions with low fees.
- Scalability: IOTA's Tangle technology enables it to effectively process transactions, making it scalable for large volumes of transactions and data exchange.
- Secure: IOTA's Tangle technology and consensus mechanism provide a secure and decentralised system, making it ideal for data exchange amongst other uses.
- IoT-Focused: IOTA is specifically designed for the IoT network, making it an attractive option for the growing industry of connected devices.
- Versatility: IOTA's Tangle technology can be used to create decentralised applications that can facilitate micropayments, data exchange and more.
Cons of IOTA
- Complexity: IOTA's Tangle technology and consensus mechanism can be challenging to understand for beginners, making it less accessible than other cryptocurrencies.
- Unproven Technology: IOTA is a relatively new cryptocurrency, and its technology is still being developed.
- Dependency on Node Operators: IOTA's Tangle technology requires node operators to validate transactions, making the network dependent on these operators.
- Vulnerable to Attack: IOTA's Tangle technology is vulnerable to certain types of attacks, such as a 34% attack, which could compromise the network's security.
- Limited Adoption: IOTA is still a relatively unknown cryptocurrency, with limited adoption compared to more established cryptocurrencies such as Bitcoin and Ethereum.
In terms of whether the pros outweigh the cons, IOTA is certainly an exciting yet challenging cryptocurrency to use.
Its feeless transactions, scalability, security, and versatility make it an attractive option for several industries.
Especially those in the IoT network.
Yet its complexity, unproven technology, dependency on node operators, vulnerability to attack and limited adoption are areas of concern that need to be addressed to ensure its long-term success.
IOTA 34% attack vs Bitcoin 51% attack?
IOTA's vulnerability to a 34% attack is a reference to a specific type of attack that can occur on the IOTA network due to its unique Tangle consensus mechanism.
In a traditional Proof-of-Work (PoW) blockchain like Bitcoin, a 51% attack occurs when an attacker controls a majority of the network's computing power.
Ultimately allowing them to control the creation of new blocks and potentially manipulate transactions on the network.
In the case of IOTA, a 34% attack is a potential vulnerability that arises from the way transactions are validated in the Tangle.
Unlike a traditional blockchain such as Bitcoin’s, the Tangle does not rely on miners to validate transactions.
Instead, transactions are validated by the nodes that are part of the network.
In theory, an attacker who controls 34% of the network's nodes could potentially manipulate transactions and double-spend coins.
In saying that however, it's important to note that this vulnerability is largely theoretical, and there have been no reported instances of a successful 34% attack on the IOTA network.
Additionally, the IOTA Foundation has taken steps to mitigate this vulnerability by implementing measures such as the Mana system, which assigns reputation to nodes based on their contribution to the network.
IOTA vs IoTeX
IOTA’s biggest competitor is a fellow internet of things focused project called IoTeX.
IoTeX is a blockchain-based platform that aims to provide privacy and security for IoT devices.
While both IoTeX and IOTA are focused on the intersection of blockchain and IoT, they differ in their underlying technologies.
The key difference is that IoTeX is built on a traditional blockchain, while IOTA uses a directed acyclic graph (DAG) structure called the Tangle.
This means that IoTeX uses a linear blockchain structure to record and validate transactions.
While IOTA's Tangle is a more flexible and scalable data structure.
In terms of speed and scalability, IOTA's Tangle offers significant advantages over traditional blockchain-based platforms.
By removing the need for miners or validators, IOTA can achieve much faster transaction processing times and lower fees.
IoTeX, on the other hand, is more in line with traditional blockchain-based platforms, which can suffer from scalability issues as the number of users and transactions increases.
However, IoTeX does offer some unique features that set it apart from IOTA.
For example, IoTeX's privacy-focused approach allows for confidential transactions and data sharing, which may be particularly important in certain IoT applications.
Additionally, IoTeX has a built-in system for managing decentralised identities and access control.
This could certainly be useful in scenarios where device authentication and access control are critical.
While both IoTeX and IOTA are focused on the intersection of blockchain and IoT, their underlying technologies differ enough to mean there’s room for both in the industry.
