IOTA designers decided to leave out the seed generation function of their software, which predictably let 3rd parties like the one in the article create a malicious seed to exploit the platform.
Every other cryptocurrency software can facilitate wallet generation seeds natively, why does IOTA refuse to implement it?
I'm simply providing historical facts. Your bias as an invested speculator is clear. https://news.ycombinator.com/item?id=15634175 https://news.ycombinator.com/item?id=15634175
The response to the IOTA hash flaw has a followup from MIT as well:
https://www.media.mit.edu/posts/iota-response/ https://www.media.mit.edu/posts/iota-response/
On Friday, MIT Technology Review published an article on
the cryptocurrency IOTA. The headline stated that the
currency “could outperform Bitcoin.” However, we here at
the MIT Media Lab have issues with the story.
Specifically, my colleagues in the Digital Currency
Initiative (DCI) recently uncovered a gaping hole in
IOTA’s software. And while that flaw has now been patched,
we certainly disagree with reporter Michael Orcutt’s
assertion that IOTA is “secure.” As the Director of the
MIT Media Lab, I felt it important we outline our specific
concerns.

Quote One:
“The rally began in late November, after the IOTA
Foundation, the German nonprofit behind the novel
cryptocurrency, announced that it was teaming up with
several major technology firms to develop a ‘decentralized
data marketplace.’” The article goes on to say: “And the
high-profile names participating in its data market pilot—
including Microsoft, Deutsche Telekom, and Fujitsu—suggest
IOTA is onto something.”
Response One:
IOTA’s relationships with top-tier companies continue to
be nebulous.
In the Technology Review article, Orcutt linked to a
November 28, 2017 blog post from IOTA that gave the
perception that Microsoft was a partner in the
marketplace. However, after a flurry of media reports
making this claim, IOTA corrected their relationship
status with top-tier companies like Microsoft, Cisco, and
Huawei in a blog post dated December 16. That the MIT Tech
Review story links to IOTA’s initial blog post instead of
the later version is misleading.
Quote Two:
Though IOTA tokens can be used like any other
cryptocurrency, the protocol was designed specifically for
use on connected devices, says cofounder David Sønstebø.
Organizations collect huge amounts of data from these
gadgets, from weather tracking systems to sensors that
monitor the performance of industrial machinery (a.k.a.
the Internet of things). But nearly all of that
information is wasted, sitting in siloed databases and not
making money for its owners, says Sønstebø.
IOTA’s system can address this in two ways, he says.
First, it can assure the integrity of this data by
securing it in a tamper-proof decentralized ledger.
Response Two:
Whether or not IOTA’s ledger is “tamper-proof,” the entire
IOTA network went down in November, and was completely
inoperable for about three days. That this has never
happened in Bitcoin or Ethereum suggests the extent to
which the IOTA network relies on the “coordinator”—a
single point of failure—and is not truly decentralized.
Also troubling, IOTA developers were able to transfer
funds out of users’ IOTA accounts. The user was then
required to participate in a “reclaim” process to request
their funds. We believe IOTA’s developers should not have
access to such funds; it’s rife with risk.
Quote Three:
Second, it enables fee-less transactions between the
owners of the data and anyone who wants to buy it—and
there are plenty of companies that want to get their hands
on data.
Now, here’s where things get really interesting. Instead
of a blockchain, IOTA uses a “tangle,” which is based on a
mathematical concept called a directed acyclic graph.
Sønstebø says his team pursued an alternative approach
after deciding that blockchains are too costly—it has
recently cost as much as $20 per Bitcoin transaction
because of high demand—and inefficient to operate at the
scale required for the Internet of things.
Response Three:
Orcutt’s claim that IOTA is free of fees is misleading.
Though perhaps not immediately obvious, IOTA transactions
are "zero fee" in exactly the same way that Bitcoin
transactions are. An important difference is that Bitcoin
has miners who can perform the proof of work for you,
while IOTA users do the proof of work on their own
devices, per transaction. However, a Bitcoin user can also
mine their own block to get their transactions accepted
into the blockchain without paying fees. To put it another
way, most people wouldn’t be interested in buying a
refrigerator operated by a hand crank, even if the
advertisement said “No electricity required!”
It’s true that transactions with Bitcoin and other digital
currencies, even when amortized over a block with
thousands of other transactions, require much more work
than transactions in IOTA. However, the claim is not that
IOTA transactions are easier—the claim appears to be that
IOTA transactions are free.
Semantics aside, this claim, which appears in IOTA
marketing materials, is deceptive; the work required is a
fee, whether or not it requires a monetary payment.
Restricting the ways in which the fee can be
paid—requiring that the work be done on a user’s own
device—doesn’t make it go away.
Quote Four:
“In August, researchers from MIT and Boston University
reported that they discovered a “serious vulnerability” in
a novel cryptographic technique IOTA was using. IOTA has
patched the vulnerability, and Sønstebø says that security
measures in place would have prevented anyone from losing
funds. The foundation has hired a third-party firm to help
it continue to develop the technique, which Sønstebø says
represents the kind of “lightweight cryptography” needed
for low-power connected devices, like sensors.”
Response Four:
Once the Digital Currency Initiative published the break
in IOTA’s curl hash function, its author, Sergey
Ivancheglo, offered two conflicting explanations for the
vulnerability.
The first explanation was that the flaw was
intentional—that it was meant to serve as a form of “copy
protection.” If anyone used this code in their own work,
he said, the IOTA developers would be able to exploit the
flaw and damage other systems that were using the hash
function. However, later, he offered a conflicting
explanation that he didn’t write the curl at all, but that
an AI wrote it.
We do not find either of these explanations convincing,
even in isolation. That they contradict each other makes
them even less so.
- redka 9y agoCopying and pasting whole articles doesn't make your point any more valuable. It's not a historical fact that what you pasted in is a response to the article I linked to because the two happened in a reverse chronological order. You'd know that if you read it since it clearly refers to those specific claims.
- 0wing 9y agoOk that's a fair point.
