I'll revisit the idea of indexing tags after the android app is done (which is top priority now).

if you're looking at the android app - I tried it on Android 4.2 and, when set into vibrate mode, receiving a new transaction now causes a SecurityException:

Code:

java.lang.SecurityException: Requires VIBRATE permission
at android.os.Parcel.readException(Parcel.java:1425)
at android.os.Parcel.readException(Parcel.java:1379)
at android.app.INotificationManager$Stub$Proxy.enqueueNotificationWithTag(INotificationManager.java:228)
at android.app.NotificationManager.notify(NotificationManager.java:132)
at android.app.NotificationManager.notify(NotificationManager.java:108)
at piuk.blockchain.android.BlockchainService.notifyCoinsReceived(BlockchainService.java:256)
...

so sounds like you just need to add VIBRATE to the manifest...

Cheers

piuk I really appreciate your service but what I just saw really ins't cool. I realize anyone who knows how to use google can find the same info, but I still don't see a reason why you need to display it automatically:

https://blockchain.info/address/1H4sGgNSRvRuiUsbucsQBNFWhZcLnL2KW1

At least give us an option to disable this in account settings or something.

Actually on second thought maybe it isn't so bad that we get reminded like this whenever one of our addresses is publicly tied to us that anyone can clearly see this. Could you give an explanation how far your labeling goes, does it follow coins or is it just for original addresses tied to a label?

I'm trying to login in offline mode to create a paper wallet as recommended by this tutorial: https://blockchain.info/wallet/paper-tutorial

There is no button. Without internet access I can still login and create a paper wallet but I can't delete the private key while the address is not synced.

Is it possible to create a new address and then delete the private key without internet access?

[piuk]

What happened to this? I'd love to use that new method, but can't find the deposit button anymore.

For the UK this will be available again Monday or Tuesday. I don't have an ETA for europe at the moment.

Can Do.

Good catch, thanks.

It's not in anyway tied to a My Wallet account. All I did was write a quick spider to check the signatures on bitcointalk and create a tag for each one found. I can remove your signature if you like, however remember if blockchain can index them then any entity (with possibly more nefarious intentions) can also. I guess just be careful posting your bitcoin address publicly. Also be aware not only about information you may have revealed yourself but also also of information that people you have sent and received transactions from have also made public.

Tagging does not follow coins. However this is probably possible by determining the change output and attaching a confidence rating.

Sorry the documentation needs updating. Instead just login as normal and then disconnect your internet. However you MUST clear your browsers cache after deleting the private keys and before reconnecting to internet or the point of going offline is voided.

Great I'm using an incognito window and it's working now. The address no longer appear when I log back to the wallet in online mode.

You should have your spider also go to bitcoin-otc user pages and get the addresses from there

There's a small mistake on one of the charts' axes.

http://blockchain.info/charts/transaction-fees-usd

The left-axis should be labeled in USD, not in BTC. This leads to confusion.

Thanks!

Piuk, I'll suggest another feature. Hope you are adding to TODO list.

I would like to see a page with map, listing the places that accept Bitcoin. See my suggestions:

1- I think you should request and add information to www.openstreetmap.org
2- Openstreetmap already have tags for bitcoin payment, see: http://wiki.openstreetmap.org/wiki/Key:currency and here: http://wiki.openstreetmap.org/wiki/Key:payment
3- Look this great example that it's opensource, from bewelcome: http://alpha.bewelcome.org/searchmembers
3.1- See on map the amazing option to (search using map boundaries).
3.2- The javascript library of the map is: http://leafletjs.com/
3.3- bewelcome information about switch from Google to Osm, http://www.bewelcome.org/wiki/Switch_to_OSM

What do you think?

I am trying to connect to the Blockchain.info wallet API, but i keep getting disconnected. I've tried the recommended wrapper for ruby https://github.com/jjeffus/rpcjson, and i've tried simply with net/http. I just keep getting this error

bc = RPC::JSON::Client.new 'https://e6152eDbf-85f7-527e-9adf-8b1dt7fa4312a:password@blockchain.info:443', 1.1 => #, @version=1.1> 1.9.3-p194 :018 > bc.getinfo Errno::ECONNRESET: Connection reset by peer

I have tried connecting through bitcoind and that works fine. Forgive me if im missing something obvious.

Continuing from https://bitcointalk.org/index.php?topic=40264.msg1355158#msg1355158

1- The green, orange and black circles bellow the map, could represent: physical store, online store, both. http://alpha.bewelcome.org/searchmembers
2- The form to add the informations to openstreetmap will be something like this but with many other fields: http://alpha.bewelcome.org/signup/3
2.1- Will have option to add the exact location on map. Openstreetmap accept add places on top of Bing satellite from Microsoft.
3- I think when the user click on the store, on map, could open a new blockchain.info page showing the detailed place information, (all fields), Google Street View....

Piuk, I really like blockchain.info design. I hate services that look "profissional" like https://walletbit.com/

[Stephen Gornick]

Because blockchain.info/wallet allows people to make wagers using funds from transactions that have not confirmed first, what happens is that you get cascading double spends, and players thinking they won big when in fact their wager was invalid if the funds for making the wager never confirm.

This isn't really a problem for most wallet users, and is probably specific to those using the SatoshiDICE page:
 - https://blockchain.info/wallet/login#send-satoshi-dice

So might it be a good idea to check the coins that would be used and warn in advance that the wager used funds which had no confirmations, or to display the caution after the wager is placed?    (or, alternatively, in the Account Options, to let me choose how many confirmations are required before Blockchain.info/wallet will use a coin in my wallet for spending?)

Bug:

I added a label to one of my receiving address but now is not possible to remove this label. It's only possible change the label name for another one. Can't leave blank.

So you would like to be able to tag transactions with a location? I could see how this would work, perhaps a live map of markers "X sent 1 BTC to X".

However there is a danger of people revealing too much about themselves without being aware of what they are doing (even with it being optional). Not only might somebody be able to predict your wallet balance and potentially what you have purchased but also your location. Thank you for the suggestion, I will add it to the list but I think perhaps this data is best suited for social networks.

Because blockchain.info/wallet allows people to make wagers using funds from transactions that have not confirmed first, what happens is that you get cascading double spends, and players thinking they won big when in fact their wager was invalid if the funds for making the wager never confirm.

The users is warned when they spend a double spend. However with the recent SD double spends the user probably wasn't warned as the inputs were respent by SD several minutes after the original transaction. Therefore at the time blockchain.info received the original transaction it seemed ok but even so eventually some of them lost against later transactions.

I could disable spending double spends completely but it might be advantageous in some situations e.g. if miners consider the fees from an entire chain of unconfirmed transactions when deciding which transaction to eventually include in a block. SatoshiDICE seems to have fixed the double spend problem for now though.

There have been reports of problems with that ruby library previously. Honestly i'm am not sure what is causing it. Will it connect to the Bitcoind RPC server?

No, this is not what I suggested. I suggested a Directory Listing with map, of places that accept Bitcoin. Maybe you understood wrongly because my bad English.

Ah ok, sorry I misunderstood. Similar to http://www.bitcoinmap.com?

Yes, but requesting/adding data to openstreetmap.org. Use map library http://leafletjs.com/. Your simple/clean and good design.

Yes, it works fine locally. I've written my own with net/http as well, but I get disconnected with that as well. I have really no idea what the problem can be. Do i nede to encode something? I just have it something like this
@uri = URI.parse('http://e6429dbf-88f7-5347e-9adf-8b65e574fda212a:password@blockchain.info:443')

SatoshiDICE seems to have fixed the double spend problem for now though.

If I receive a bitcoin transaction, Blockchain.info/wallet lets me immediately turn around and use that coin in a wager on SatoshiDICE (or any other transaction).  What I am requesting is that when this occurs using the SatoshiDICE page, that if there is at least one coin that will be used that has zero confirmations then the user gets reminded somehow that these wagers made with 0/unconfirmed sometimes are invalid (as SatoshiDICE payouts will only confirm if the wager itself confirms).
