![]() According to IOTA cofounder Sergey Ivancheglo, the “practical attack” demonstrated by the DCI researchers only works in a limited number of improbable situations that would affect a negligible number of IOTA users, mostly thanks to a closed-source and centralized solution called the “ Coordinator” that helps secure the network. The IOTA developers wrote back that the researchers had misunderstood Curl, saying, for example, that the possibility of finding cryptographic collisions-the point at which a cryptographic function is generally considered broken-was intentional. In July, Heilman and the DCI researchers disclosed an alleged vulnerability in Curl that, they said, would effectively let anyone forge IOTA transactions. This is all pretty much in the public domain already Heilman and his colleagues (including Neha Narula at MIT) published their work in September, and ahead of the vulnerability disclosure in August IOTA changed their algorithm from Curl to the well-documented Keccak algorithm.Įmails between the IOTA team and Heilman and Narula were leaked to the IOTA-focused blog The Tangler over the weekend, and reveal that the initial July email from Heilman resulted in a correspondence that stretched into September between DCI researchers and IOTA developers. (IOTA says it reached out to the DCI team months earlier.) After disclosure, the IOTA team disputed the vulnerabilities’ existence. Last July, Ethan Heilman, a Boston University researcher affiliated with MIT’s Digital Currency Initiative, informed the IOTA team in an email that he and his colleagues at MIT had discovered “serious cryptographic weaknesses” with the current implementation of Curl in IOTA.

IOTA is the tenth-largest cryptocurrency with a roughly $5 billion market cap. IOTA is a cryptocurrency that’s been around since 2014 and is designed for micro-transactions between machines in the Internet of Things. But wait, you may be asking, what is IOTA and why are a bunch of really smart people very mad about it?
