Be careful about those zip files. I haven't looked, but they may contain
the tibannebackoffice.exe wallet stealing malware. It has appeared in
other MtGox2014Leak.zip files.

Re: [Full-disclosure] OT What is happening with bitcoins?

[Ron Scott-Adams]

Julius hit the nail on the head here. Transaction malleability is not some 
heretofore undiscovered bug in the Bitcoin implementation. It was a known 
entity long ago, and presumably with the creator(s) awareness. It really isn’t 
a problem itself; it’s perfectly mitigable with the correct implementations on 
the exchange’s side. It’s worth noting nearly all of the FUD surrounding BTC 
comes down to mistakes made with and among exchanges. Exchanges of any kind 
carry risk, and a new kind of exchange such as this is bound to have some 
serious question marks in the first many years of existence.

For more on transaction malleability and the technical considerations, see 
https://en.bitcoin.it/wiki/Transaction_Malleability, noting especially the 
following:
“...this does mean that, for instance, it is not safe to accept a chain of 
unconfirmed transactions under any circumstance because the later transactions 
will depend on the hashes of the previous transactions, and those hashes can be 
changed until they are confirmed in a block.”

The above is a huge note, and is made clear elsewhere as well. However, 
mistakes around this were still made, and continue to be made today. Live and 
learn, caveat emptor, etc.

Saying that the malleability thing is an issue with bitcoins is like saying
that sql injection is an issue with mysql.

Re: [Full-disclosure] OT What is happening with bitcoins?

[chedder]

Well, from my understanding. the transaction malleability issue,
 isn't a problem with the protocol itself.
but the specific exchanges implementation of it.
not all exchanges where even effected by it to begin with.
and with japans decision to keep bitcoins completely unregulated.
it's unclear if mtgox stole the coins and used all this as an excuse.  or
what.

More to the point, has the transaction malleability issue been fixed that 
caused Magic’s downfall?
Even though most exchanges just code around it, it’s still kind of a really big 
issue if it isn’t fixed. :d

Bitcoins are doing great actually. =)
Used to be worth 0 a few years back, useless, and now you can use them to buy 
some stuff.

Read on theregister that bitcoins are in trouble.

Allegedly mtgox lost $400M maybe related to
transactions.

Are the bugs in bitcoin or just sufficiently
many ones got rooted?

Is bitcoin still alive?

[Brandon Perry]

1. The people losing their bitcoins from hacks were amateurs at software 
engineering.

2. One of bitcoins greatest purported strengths (anonymity) is becoming a 
severe weakness because you cant easily track down who stole the bits.

3. I dont think any of this is a result of bugs in bitcoin.
