Is the attack still going?

Apparently not. Source
2002  Bitcoin / Bitcoin Discussion / Re: tainted bitcoins on: October 06, 2015, 06:23:56 PM
information and freedom exclude eachother?

They do not. However, some information might not be useful at all, or just that: information.

It's praiseable if you want information, that you feel the need to search and find. Some topics have been already laid out, and there's also a discussion thread posted a few posts back. But from that to anything blacklist related... It goes a long way, and "blacklisting" is something we definitely don't want.

If someone receives tainted coins, he or she would definitely like to be able to spend them, and not have them blocked just because they once were used for scams/were in an address of a scammer.

voisine, since you're around, I'd like to call the attention to this issue on the other breadwallet thread (don't know why people don't simply move discussion to here... but that's another topic Cheesy)

Although I think I'm not quite following the user's issue, it seems that seed data is somehow stored on iTunes, outside of a phone backup. Is that correct? if yes, isn't that another place to search for vulnerabilities regarding finding out what is one's seed? I don't know exactly how is iTunes data encrypted and although stealing a seed from iTunes data might seem tricky or something that probably no one will try, it's something that I find relevant to discuss...

And what about phone backups? Are they handled the same way? breadwallet data certainly goes on those, I guess.

The wallet seed is stored in the iOS keychain, marked "this device only". This means that you can only restore it from backup to the same device it was created on, so you are protected even if an attacker hacks your iCloud account or gets ahold of your iTunes backups.

Wasn't aware of that, thanks Smiley

Besides this, Satoshi seems to have had quite a few reasons to develop
Bitcoin such as fleeing from banks, creating a trustless system, etc.
OK. So my reason is to protect your life savings from this ponzi scheme called bitcoin Smiley
I want to prove that decentralized trustless system can not exists in long term.
It either transforms to centralized system or loses its security.

Since you're giving me valid advice, I'll give you valid advice too: don't put all your eggs on the same basket Smiley

As for long term decentralization, we'll see. The system may fail, but competition may rise and prove to be even more up to the task (that's why some testing is important too).

Problems will eventually find a solution where there is a need.

Why don't we "blacklist" all fiat notes connected to crime, too? Roll Eyes

lol agree. and maybe your fiat is intervention of crime too, so beware Cheesy

If I'm not mistaken, I've read exactly on these forums that a quite high percentage of dollar bills have a trace of cocaine powder in them. I don't know if that's true evidence, but it just makes us remember that many fiat bills we hold might have went through the hands of criminals. Do we stop using them for legal purposes, just because of that? Obviously not...

Without a node with modified code how does one get around to doing what you're doing in an automated way?
Some kind of pseudo-node. No code from any other client.

Understood, thank you.

Also, a follow up question, what are your main reasons behind this?
Are you doing this to prove a point, like with the transaction spam attacks?
Just because I am able. Isn't it funny? I have not any other reason today. But... I have some ideas for future.
Why did Satoshi invent bitcoin? I really think he had the same reason - because he was able to do it.

Although the groundwork and the ideas that are the basis to Bitcoin were laid out throughout the years, Bitcoin is still quite innovative, so I'm not sure Satoshi started Bitcoin knowing he could develop it, finish it and release it.

Besides this, Satoshi seems to have had quite a few reasons to develop Bitcoin such as fleeing from banks, creating a trustless system, etc.

Despite this, you are obviously free to do something for no reason in particular, but I don't think you'll let this opportunity escape and you'll eventually put this "stress test" in use to prove a point (I think you're already proving it, unintentionally or not)

How does breadwallet handles the malleability attack ?

EDIT: you can read about this new ongoing attack here https://bitcointalk.org/index.php?topic=1198032.0

Pretty well, I'd say. It shows both transactions, one saying "INVALID". Doesn't seemed to be confused with the 2 different hashes Smiley

Besides the invalid warning, if you open more info on the transaction it says "double spend" on the status part.

Will NY users flock to Gemini? I think they'll have a nice userbase, but the question is if investing to serve that userbase will be worth it in what concerns profit in the long run... I think they'll have success Smiley
2010  Bitcoin / Development & Technical Discussion / Re: New transaction malleability attack wave? Another stresstest? on: October 05, 2015, 05:40:25 PM
Does one have to control a significant number of nodes to disrupt a lot of transactions?
No need to have even one node.
The stress-test is paused right now. You can see the statistics and network health here:
http://statoshi.info/dashboard/db/transactions
Third chart "Transactions Accepted vs. Rejected"

Statoshi has so many charts, I forgot to check it for that one, thanks Cheesy So it's confirmed, when I made my transaction, attack was still ongoing.

Without a node with modified code how does one get around to doing what you're doing in an automated way?

Also, a follow up question, what are your main reasons behind this? Are you doing this to prove a point, like with the transaction spam attacks?
2011  Bitcoin / Bitcoin Discussion / Re: How do you envision the future of Bitcoin? on: October 05, 2015, 05:34:04 PM
Whatever the cryptocurrency of the future might be, I envision it starting to replace fiat in most of our everyday transactions.
2012  Bitcoin / Bitcoin Discussion / Re: tainted bitcoins on: October 05, 2015, 05:31:54 PM
Why is this relevant? Bitcoin will cease to be as useful as it is if we start treating 1 Bitcoin from address X differently from 1 Bitcoin from address Y. These types of researches and lists will only be useful to make white and blacklists, which are very much the opposite of what we're trying to accomplish with the whole cryptocurrency technology.

Why don't we "blacklist" all fiat notes connected to crime, too? Roll Eyes
2013  Bitcoin / Wallet software / Re: iOS Bread Wallet on: October 05, 2015, 02:53:18 PM
I can not !
there it is asking me for "Recovery Phrase to wipe it and start/recover another."
and i do not have that

Edit:
sorry this is such a pain ... , i just wanted to install a test wallet,(did not save anything) and planned to install a proper wallet after
but now i can not get rid of that test
 Undecided

I'm not quite sure I'm following your issue.

Does the wallet reappear after a simple sync with iTunes? If yes, I find that really odd, app info may be be nicely encrypted, but this is still another way to get access to a seed, I think (but that's another issue)

If disabling automatic sync on iTunes is an issue for you, try to delete everything breadwallet related on iTunes and see if it does the trick.
2014  Bitcoin / Development & Technical Discussion / Re: New transaction malleability attack wave? Another stresstest? on: October 05, 2015, 02:49:18 PM
Apparently this is still ongoing, had it happen on a transaction of mine. The question is why and how...

Does one have to control a significant number of nodes to disrupt a lot of transactions?

How can i erase Breadwallet + all its data ?
i have a test version on my iPhone 6, never save the passphrase (seeds)
i know right  Roll Eyes
i want to erase it and start with a new fresh wallet (but the old password always comes up)
Huh
tx

On the settings menu, delete the seed and start fresh.

- start/recover another wallet ?
i can not, do not have the old seeds or password
??

I erased the whole phone already
installed new wallet, set up new wallet, all worked
but the sec i do a sync with iTunes the old wallet comes back and i am stuck again
 Huh

Exactly, that's the option. No need to restore your phone just for this Cheesy You get the old wallet back because that's the information synced with iTunes. When you restored, did you set it up as new phone or did you restore from an iTunes/iCloud backup?

Where are you shipping from? I might be interested at least on the Raspberry Pi case and on the SD cards.

Shipping from US. OP updated.

Thank you

How much would it be shipping to Europe? I can PM you an address.

2020  Bitcoin / Wallet software / Re: Armory-like SPV wallet? on: October 04, 2015, 02:52:21 PM
What features are you looking for?

Bumping this thread because I like Armory's fragmented backup, but I just cannot devote 80 Gb of disk for blockchain + Armory cache. I tried Electrum's multisig, but I don't understand it: I need to add other signers' master key.

Most, if not all, SPV wallets are based on seeds... You can fragment that seed. As for fragment security I'm not sure what would be possible to do. Maybe hash the seed? Or maybe scramble the words.
