Even in the cryptocurrency world, where miracles are commonplace, IOTA stands out as a unique phenomenon.
Launched in 2014 as a crowdfunding project, IOTA introduced itself as a novel technology akin to—but superior to—blockchain, earning its reputation as a "variant" of blockchain. Within two years, it climbed into the top 10 cryptocurrencies by market capitalization, rarely dropping below the top 15.
By late November 2017, IOTA’s market value skyrocketed, surging from $4 billion to over $10 billion in just a week, peaking at $15.4 billion. In February 2018, IOTA’s price spiked above $2, with a 24-hour trading volume exceeding $100 million (per CoinMarketCap). Early investors reportedly gained 1,500x returns, making IOTA one of the few digital assets to deliver such extraordinary profits.
This surge may be attributed to a leaked email incident in late February 2018, which brought to light a long-standing security dispute between IOTA and MIT’s Digital Currency Initiative (DCI).
Part 1: IOTA—The Pillar of the Internet of Things
IOTA’s uniqueness lies in its underlying technology. Unlike traditional blockchains, it employs DAG (Directed Acyclic Graph), branded as the Tangle, to facilitate decentralized, irreversible data transmission and cryptocurrency functions. Designed for machine-to-machine payments in the Internet of Things (IoT), IOTA is often hailed as "Blockchain 3.0" (Bitcoin: 1.0; Ethereum: 2.0).
Key Features:
- Zero Fees: Unlike blockchain, IOTA eliminates transaction fees by allowing every participant to validate transactions.
- Scalability: The Tangle grows more efficient with increased user activity, avoiding bottlenecks common in PoW/PoS systems.
- IoT Integration: Tailored for microtransactions among connected devices, positioning IOTA as a backbone for IoT ecosystems.
Part 2: The DCI-IOTA Feud: Security Flaws or Miscommunication?
The conflict dates back to 2017:
- May: IOTA invited DCI to audit its Tangle protocol.
- July: DCI claimed to have identified vulnerabilities in IOTA’s proprietary Curl-P hash function, warning of potential theft risks. They recommended switching to established algorithms like MD6.
- August: IOTA replaced Curl-P with Keccak, calling DCI’s findings "deliberate obfuscation" to deter code plagiarism.
- September: DCI published its report, triggering a 15% price drop. IOTA countered, accusing DCI of breaching disclosure ethics and misrepresenting flaws.
The feud escalated when 125 pages of private emails were leaked in February 2018. Excerpts revealed heated exchanges:
"Ethan [Heilman] is in blatant conflict of interest… This is no longer about academic rigor but a desperate money grab."
—David Sønstebø (IOTA Co-founder)"If you’ve fixed all issues, why publish? Your rush to media pre-peer-review is unprofessional."
—Sergey Ivancheglo (IOTA Developer)
Despite the drama, the market responded positively—IOTA’s price soared to $2, suggesting investors sided with IOTA’s narrative: DCI failed to prove actionable vulnerabilities.
Part 3: The Core Debate: Flaws or FUD?
DCI’s Allegations:
- Curl-P Collisions: Claimed the hash function was susceptible to attacks, enabling transaction tampering.
- Academic Standards: Criticized IOTA for reinventing cryptography instead of using battle-tested solutions.
IOTA’s Defense:
- "Copy-Protection": Admitted "flaws" were intentionally added to deter code forks.
- Practical Irrelevance: Argued attacks required unrealistic preconditions (e.g., insider knowledge + user cooperation).
Conspiracy Theories?
Some speculated DCI’s ties to Zcash and Lightning Network (competing technologies) fueled bias. DCI’s neutrality claims were further questioned after the emails revealed aggressive posturing.
FAQs
Q1: Did the leaked emails prove IOTA was insecure?
No. The emails revealed DCI’s inability to demonstrate exploitable flaws, boosting investor confidence.
Q2: Why did IOTA use a custom hash function?
To prevent code cloning—a controversial but strategic move in open-source ecosystems.
Q3: Has any attack exploited these "vulnerabilities"?
Not in six months since DCI’s report, despite widespread crypto hacks elsewhere.

Conclusion:
The IOTA-DCI clash underscores the tension between innovation and academic scrutiny. While IOTA’s market resilience suggests the storm has passed, the debate over "security through obscurity" vs. transparency lingers.
