http://www.tangleblog.com/wp-content/uploads/2018/02/letters.pdfI read the leaked emails between the iota team and DCI.
I try to make a summary of the 124 pages of emails:
DCI: hey i found some vulnerabilities in iota.
IOTA team: thanks for telling us. What is the weakness?
DCI: something with curl (don't roll your own, not peer reviewed, cryptography!).
IOTA team: thanks, we were planning to change it to Keccak. How were you planning to attack iota based on the vulnerability?
DCI: don't know, i am busy right now. When are you going to take care of the vulnerability?
IOTA team: wait let's get the facts straight and analyze your attack.
DCI: Trust me it is not done to roll your own cryptography (no go).
IOTA team: ok, but what about the attack?
DCI: You fixed the vulnerability not? so we can publish our findings, you can read the attack in publication.
IOTA team: How about us responding to the attack? We still think an attack would not be successful.
DCI: We are done with you, don't insult us. We are going to publish.
Yes, that's a good summary.
The obvious next question to ask is why did DCI behave this way, and why are other academic cryptographers like Matthew Green attacking IOTA team?
Answer is jealousy and greed as far as I can tell, these academics want to earn big money like early crypto tech pioneers, they are very jealous of CfB in particular as creator of NXT and IOTA, and they work with rivals of IOTA to make big money if they can too, and they want to use their 'credibility' to bring down a competitor.
When all this comes out, and it will, many reputations will be destroyed, but so far they are doing some short term damage to IOTA, but eventually this episode will be legendary in IOTA's history.
