Apologies, yes one server lost it's database connection. If it problem ever occurs again it should auto-reconnect now.


For now a tag submission page is available at http://blockchain.info/tags. Also for a bit of geeky fun I indexed the addresses contained in signatures from bitcointalk.org example: http://blockchain.info/address/1H4sGgNSRvRuiUsbucsQBNFWhZcLnL2KW1

It doesn't include up or down voting as the tags in this context probably serve a slightly different purpose than your original idea giszmo. Which was to allow people to tag addresses as belonging to scammers, add comments etc? While I could see this being useful in some situations it has the danger of morphing into a blacklist which in my opinion is a bad idea all round.


Yep, your right on both counts. Extending this feed idea a bit further, what if it wasn't just for individuals websites but could the feeds could serve as a public directory of users as well. Basically a map of [email protected].

For example wallet services could all have a "Make address public" option which would then publish an address and label to the wallet services bitcoin_tags.json feed. Other wallet services can then index the feed of each service to build a public address book.

e.g. If I published the label "piuk" in the blockchain feed. Instawallet could then index the feed and resolve "[email protected]" to the correct address. Bitcoin-Qt could publish to a @bitcoinfoundation.org feed, Electrum to @ecdsa.org etc.


It's a nice trick, but is missing the most desired property that embedding data in the blockchain has, in that data is guaranteed to be permanently stored for as long as the bitcoin network is running.


This should be patched this now, the mixer will be much more likely to pay a fee from now on.

Has their always been a password on the iphone app? I've used mine a few months and right when I sent a large transaction to my phone the app stopped working. I logged in with my pc about a month ago and backed up the wallet or atleast I though. I linked my email to my account but now it says email not found, and without a password my wallet file doesn't let me access it either.

There is a problem with the mixer: it does not pay a fee for the outgoing transaction, so often it takes ages to confirm.  I have been waiting four hours so far 

True … sort of. I'd be more interested in such a man in the middle being found in the wild than that I fear the risk of it aka I consider https being optional should be fine. It could be marked in the list as extra feature. Also showing historic tags or at least the timestamp of when a tag changed would help to get people aware of potential issues.

You should only trust tags fetched via https, otherwise a man-in-the-middle could hijack the .json file and replace the address and signature.

(and I think you'd want "tags" to be an Array of Objects...)

RE: adding data to the blockchain: Did you see Stefan Thomas' nifty idea for using ECC math to tie a hash to a transaction without any blockchain bloat?

Now all seems to work 

I can confirm that blockchain support is top notch. I had a problem and they got back to me in far less than a day. Turns out my phone carrier doesn't support their sms bitcoin buying service but I imagine that is out of their hands.

The first times this happened to me I got a bit worried too   But it looks like blockchain.info has a failure mode where it looses connection to some backend, and data does not update.

I've a problem with the wallet too. I've made a transaction 12 hours ago (and the receiver has got his btc), but in my wallet don't shows up. If I try to move some btc I got a "No operations allowed after connection closed.". I've the android app too and sometime don't let me login, when I success in login  the wallet shows the correct amount of bitcoin and the past transaction and btc transfer works.

I'm having problems too, looking up any address.

Edit: All is good now.

piuk - getting

"Error getting wallet balance" repeatedly starting ~11:45pm EST 11/15 with your online wallet service. i've tried refreshing, logging in/out, different browsers, same result

it also says, incorrectly under transactions: "Normally your bitcoin transactions would be listed here but you have not made any yet." (many have been made)

creepy man...

This would make most sense for you as this would be an incentive to open an account on blockchain.info. Up/Down-voting could be done by "donation" addresses which again would be good for you.
As long as you show the amount of donations as justification to rate something high, you should not be blamed for misrepresenting stuff and upon clear abuse you could close accounts or users and mark the tag as coming from a closed account. Showing tags from closed accounts last, only optionally or not at all would also be very clear to the user.

As you said, this would be a very temporary thing and should be avoided for the sake of bitcoin.

You would still need a way to get aware of these files. I see this approach as the most open one although people might be more careful with scam accusations due to the real world identities linked to their servers – which of course is good for your liability.

I see what you mean. The foundations for an address tagging system are in now.





So just a good system is needed for users to submit their own tags. Either:

- Directly on the block explorer pages, I'm not quite what this would look like since address pages are quite cluttered anyway. Maybe just double click in place to edit an address.
- A new page specifically for submitting, up / down voting and reporting spam tags.
- Have an address that you can send a transaction to which contains a tag embedded within one of the scripts. This is abusing the blockchain a bit though.
- json file which you can upload to a webserver which will blockchain will index. Downside is you can't tag other people's addresses.

I'm not sure which would be best, what do you think?

Not sure if I'm following you. http://fluxcards.de/bitcoin_tags.json now holds a signature of "http://fluxcards.de/testing tags" signed with the address in question.

I do agree this is a very safe way to get people identify their own addresses but my original idea was to have a way to also tag other addresses. Scammers will not give their own addresses a scammer tag. Many very public addresses scream to get indexed somehow but their owners won't host such a file. Yet I'm sure people would pay to enter addresses in some index.

I'm thinking about doing it myself but blockchain.info already has most things in place needed to implement such an index and it would definitely drive traffic to your site if the bitcoins paid to tag stuff is not enough of an incentive.

What about this... The owner of a website puts a file on their website called bitcoin_tags.json or something like that. This would server a similar purpose to sitemap.xml but instead contains a number of bitcoin addresses and labels.

For example http://wikileaks.org/bitcoin_tags.json

{
 "tags" : {
  "address" : "1HB5XMLmzFVj8ALj6mfBsbifRoD4miY36v",
  "tag" : "Donations",
  "sig" : "signature of concatenated tag and domain"
 }
}

Once the owner of a website has added the file they can suggest that blockchain.info indexes it, once indexed blockchain.info will display the new tag accordingly. This has the advantage of.

* maintainable, webmaster can update bitcoin_tags.json as they choose. Deadlinks will be removed from the database.
* Decentralised, any service can index tags.
* More secure, both the domain and the address signature is verified. Tags can be independently verified if necessary and little moderation is needed.


This can be done, but the main devs have made it clear they do not want messages embedded in the blockchain.


It is enforced by us and is unlikely to be changed for the foreseeable future, sorry.



This is really hard for me to test because the results sets are large. I need to find an example of a specific transaction which is definitely missing.

ok, I can follow your chain of thoughts but can't find out if the limit was imposed by you or the payment processor.
I can as well 'prove' it's my phone (have the PIN/PUK card that was issued with the SIM).
just want to dump 100+ pounds in that phone payment service because it's a prepaid SIM and I have no other use for it unless I can sell that card to someone else. nvmd. will set up a monthly reminder to get rid of it in tranches ...

I'm happy you like the idea

People will know that tags can be bought easily. Show how much was paid for each of them.
Scammers will get scam-warning-tags just underneath – and you get money for that.
You could distribute the money paid for tags against your TOS to those that tagged the tag as scam.
If you charge a minimum fee for tagging, you can afford to moderate the tags.

If patrolling/taking responsibility for tags is not what you want to do, I suggest you do as follows:
Provide a tool to efficiently embed messages in the blockchain in combination with a payment to one of your addresses.
Provide a site that lists all these comments.
