There's a typo on http://blockchain.info/wallet/send-anonymously:

"taint analysis calculationts"

in that case there's also a 'grammo' (?):

ah 'puncto' is a good term; i wonder if that's really what the missing hyphen should be categorized as.

I have two factor login enabled using a gmail account, but I don't seem to be getting any emails, so I can't log in.  Nothing in spam folder either, anyone else having this problem?

Simply amazing work.  And I'm also very excited you finally started to charge for something. 

Thanks hazek.

If you're charging a 1.5% fee for this anonymous send service, how are you going to withdraw your fees? It strikes me that it'd be very easy for you to create a block of coins tainted by every coin sent through the service, which itself, should it get into wider pools of coins like instawallet, would create tainted blocks of coins that would be quite hard to send through the mixer again... Limited by the 250 depth limit, but still. Similarly anyone can use the mixer a few times to create their own "ultra-tainted" coins, aided by the fact that the mixer will always give you coins that haven't been tainted by the total sum of the taint you already possess. This doesn't even need to be very expensive if you taint a small amount of coins each time, so the 1.5% fee isn't very high, and use them to taint a much lager amount which you then send to something like instawallet.

Given how thoroughly tainted the future could be it also occurs to me that what you will eventually see is miners selling their untainted coins to the mixer, which then leads to pools inserting transactions with unusually high fees, which then leads to pools conspiring to reverse said transactions. Not to mention the question of are mining payouts tainted by the coins which lead to their fees?

Note: for all the bad connotations of the word taint, imagine how much longer and convoluted the above message would be if we had decided to call it coins' provenance.

Fees are withdrawn to a separate private wallet which is used only as a reserve when not enough funds are available in the shared wallet. It is intended that no significant amount of funds will be kept in either wallet but the mixing will be much more dynamic e.g. Users A & B make anonymous transactions, User A receives B's coins, User B receives A's coins within a few minutes, rather than funds going into a large shared wallet and being "tainted" by all funds in there. It depends on how much volume is being transacted though.

In a scenario where funds are pooling in the mixer and no un-tainted coins can be found an email alert could be sent out to wallet users with suitable clean coins asking them to send the coins to the mixer (in which case they would earn the 1.5% fee instead of blockchain.info).

As Deepbit guessed 1Vay is banned from being included in wallet calculations due to high load.

Is creating multisigs still not available ?

No M-Of-N is not back yet.

With the anonymous send service couldnt a person who is following the blockchain still follow it by calc the fee and seeing what address a few blocks down gets that value? Perhaps adding a customizable delay and even multiple output addresses would help. Allowing customizable %'s for multiple outputs would be fantastic!

I just want to praise blockchain.info for both its features and its site design. I can't think of a website that is such a joy to use.

Keep up the good work

i'm not sure if this is a bug or not, but i'm getting some unexpected output from one of the API's.

the transaction hashes vs transaction amounts here:
http://blockchain.info/address/1SyrzeDxhDeB8eML9YnRPMefH6veyJHaS?format=json

does not seem to match the hashes / tx totals here:
http://blockchain.info/address/1SyrzeDxhDeB8eML9YnRPMefH6veyJHaS

any idea what's going on with that? or am i just reading it wrong.


they seem out of alignment like this:

A's hash with  A's total
B's hash with [some invalid tx data]
C's hash with B's total
D's hash with C's total
E's hash with D's total

When using Send Money and choosing "Custom" transaction type, the default for Return Change is New Address. 

However, that doesn't generate a new address and behaves as if I had selected Any Address.

This could possibly be an issue. I'd like to keep the fixed fee so you know exactly how much will be received. I've altered it so that amounts > 1 BTC will be sent in at least 2 separate transactions (split at a random %) and spaced at least 30 seconds apart.

Multiple output addresses could certainly be an option, the mixing alog will be improved over time. There is also now significantly more funds available in the mixer.

Thank You Scott.

I couldn't see anything that looked overly wrong. Are you looking at the "advanced" addresses page? e.g. http://blockchain.info/address/1SyrzeDxhDeB8eML9YnRPMefH6veyJHaS?show_adv=true

Normally address pages hide some inputs and outputs which are not considered relevant and hence the API output will be different.

Thanks for the heads up, this should now be fixed.

Also you can now select the change address when sweeping.

i didn't look at the advanced page, but it's not to do with inputs/outputs.

perhaps i'll start with a simple question: why does the transaction b87991851fa2286053b85af3d55cde3212472352f8bb246a6621763b849b63ac on this JSON output have no 'time' attribute?

http://blockchain.info/address/1SyrzeDxhDeB8eML9YnRPMefH6veyJHaS?format=json

this is the first and only case i've ever seen where a transaction is being returned with no timestamp.

Another wallet bug report, I think...

when sending money I usually use a custom send, where I specify the address I want the BTC to come from, and have the change return to the same address.

I'm also usually adding a small fee for the miners.

Anyways, teh coins send OK, but I am often seeing an error message that says "Error pushing transaction output" or something like that in a read box on the right hand side of the screen.

Like I said, though, it seems that the transactions are going out just fine.

Mixing Service Now Live

https://blockchain.info/wallet/send-anonymously

I created a forwarding address on that page and it worked great.  What happens if someone sends more funds then what is available in the mixing wallets?

[thirdlight]

Can't seem to send transactions - stuck at "Loading transactions" or "Saving wallet". Just me?

Thanks, bug report received.

The funds will sit in the wallet until either fresh coins are brought or another person make an anonymous transaction with suitable fresh coins. I will be improving how this works shortly.

Can't seem to send transactions - stuck at "Loading transactions" or "Saving wallet". Just me?

I've had one or two reports of this. Are there any errors in the javascript console? http://webmasters.stackexchange.com/questions/8525/how-to-open-the-javascript-console-in-different-browsers

Or if your able to open the "Web Inspector" in chrome or safari are there any network requests that are taking a long time to complete?
