IOTA (technology)
In 2015, four researchers named David Sønstebø, Dominik Schiener, Sergey Ivancheglo, and Serguei Popov created a new digital currency called IOTA. They chose the name from the smallest letter of the Greek alphabet to symbolize its potential for tiny transactions. The team needed money to build their vision, so they held an online public crowdsale later that year. Participants bought the IOTA value token using other digital currencies like Bitcoin. Approximately 1300BTC were raised during this event, which corresponded to roughly US$500,000 at that time. This initial funding allowed the network to go live in 2016 with a fixed supply of tokens distributed pro-rata over the early investors.
The IOTA Foundation was chartered as a Stiftung in Berlin in 2018 to oversee research and development efforts. Early token investors had donated 5% of the total supply to fund these activities back in 2017. Internal leadership disputes soon emerged between founders David Sønstebø and Sergey Ivancheglo. Ivancheglo resigned from the board of directors on the 23rd of June 2019 following the conflict. The foundation officially parted ways with David Sønstebø on the 10th of December 2020. In November 2023, the IOTA Ecosystem DLT Foundation was created in the United Arab Emirates to facilitate growth in the Middle East. It became the first crypto-centric organization approved by regulators of the Abu Dhabi Global Market. Later in 2024, IOTA received certification as a Sharia-compliant company. The Imperial IOTA Infrastructures Lab launched at Imperial College London in 2024 with £1 million committed by the foundation.
On the 8th of September 2017, researchers Ethan Heilman from Boston University and Neha Nerula from MIT reported potential security flaws in the Curl-P-27 hash function. The IOTA Foundation faced backlash for its handling of this disclosure, including legal threats against security researchers. A major fraud occurred in January 2018 when more than US$10 million worth of tokens were stolen via a malicious online seed creator. This incident involved over 85 victims and remains the largest fraud in IOTA history. Law enforcement agencies in the UK and Germany arrested a suspect from Oxford, England in January 2019. Another breach happened on the 26th of November 2019 when a hacker compromised over 50 seeds through a MoonPay payment service vulnerability. Approximately US$2 Million was stolen before the IOTA Foundation shut down the coordinator node on the 12th of February 2020 to stop further thefts. Users had until the 7th of March 2020 to migrate their seeds before the network restarted on the 10th of March 2020.
The IOTA network operated as a centralized system where validity depended on milestones issued by a special node called the coordinator. In 2019, the foundation announced plans to operate without this central authority using a two-stage update process. The Chrysalis update went live on the 28th of April 2021 for version 1.5 of the protocol. This release removed controversial design choices like ternary encoding and Winternitz one-time signatures to create an enterprise-ready solution. A testnet for the follow-up Coordicide update was deployed in late 2020 with the aim of releasing a final distributed version in 2021. The goal remains to create a network that no longer relies on the coordinator for consensus mechanisms. Developers continue working on these updates to achieve full decentralization while maintaining security standards.
IOTA uses a directed acyclic graph structure known as the Tangle to store transactions instead of traditional blockchain blocks. Network participants must approve two previous transactions for every new transaction they issue without paying fees. To prevent spam, every transaction requires computational resources based on Proof of Work algorithms to solve cryptographic puzzles. The Fast Probabilistic Consensus algorithm forms agreement on double spends through randomized thresholds generated by a Decentralized Random Number Generator. This approach differs from Bitcoin's Proof of Work which creates significant financial burdens for minted block rejection. IOTA utilizes Proof of Work only as a rate controller rather than for consensus formation itself. The total token supply is fixed at 2,779,530,283,277,761 units stored in wallets protected by 81-character seeds similar to passwords.
Corporations like Jaguar Land Rover, STMicroelectronics, and Bosch have developed proof-of-concepts using IOTA technology within the automotive industry. Smart city testbeds utilize the platform to establish digital identity systems and manage waste or local energy trading. Project Alvarium under the Linux Foundation employs IOTA as an immutable storage mechanism for validation purposes. Privacy-focused search engine Xayn uses IOTA as a trust anchor for its aggregated AI model. In 2024, IOTA partnered with Eviden to announce the Digital Passport Solution tracking battery life cycles and carbon footprints. The Eclipse Foundation launched the Tangle Enterprise Edition Working Group on the 11th of February 2020 alongside the IOTA Foundation. Critics noted mixed reception regarding early data marketplace pilots where some participants questioned the extent of foundation involvement in corporate partnerships.
