The Blockchain.info app is back on the app store…no idea how that happened, but install it now before Apple changes their minds again.

Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

Unfortunately, it is not the Blockchain for iOS wallet app, but instead just their block explorer utility. [Update: Apparently, the real deal -- full wallet.] |

I wonder if Apple has had a room full of aspergic chimps working on attacks to clear out coins from iOS Blockchain.info wallets, and now that they think they've developed the perfect attack, they re-release the app?
[/tinfoilhat]
No, that sounds ridiculous

A wallet on blockchain.info is inherently insecure. You should never have anything in it you would not be willing to lose. Putting the app on top of that adds a few potential security threats sure, but it is already an assumed distrustful environment. Leave the real wealth in the real wallet, put a few coins in this when going out, beer fund  Hmmmm, not from the way that piuk describes the operation of the blockchain.info wallets. They appear to be a fairly ingenious method of securing online wallets (private key is generated, stored and encrypted locally, then signatures are used to access the funds. Not sure how they validate the signatures! But it seems to work) |

You guys should put your money where your mouth is and stop supporting Bitcoin blocking Apple. Buy some Bitcoin loving Android phone.

Yes, that's what tin-foil Carlton was concerned about, the open source aspect. I do understand that this has not done the Satoshi client any harm (far from it), but I have a good idea of how many developers are throwing their collective nous at that project (and also a good impression of their calibre as coders). Plus there's plenty of other evidence about the extent to which others disseminate and analyse the source. With blockchain.info wallet, piuk appears to be the sole developer. Not trying to cast any aspersions against piuk, he appears to have done a great job judging by the feedback in the main thread, but I'm still not quite confident enough to use the app. I will be sitting back and waiting for the moment, as there's no compelling use case for me (yet) |

Since the code is open, people can modify, compile and publish as an app. Or simply wait for the compiled version from Qkos Services Ltd and change it (Man-in-the-Middle). Anyway to be sure? |

That attack won't work with the app store, the signatures would fail. As far as downloading a malicious version the same advice goes for any other bitcoin software, just make you you download it from a trusted source. You could easily download a recompiled version of the mainline bitcoin client that was modified. Just be vigilant. |

I can't remember the technical details, nor am I an authority on them to begin with, but I do remember making a decision to move some coins to blockchain.info after reading some previous threads. It would be nice to get a final determination on this some time. |

Awesome.

Buy a TREZOR! Premier BTC hardware wallet. If you're reading this, you should probably buy one if you don't already have one. You'll thank me later.

Nice to know. Some questions remains: Who checks the signatures? How often? |

Unfortunately, it is not the Blockchain for iOS wallet app, but instead just their block explorer utility. not even it is just to view unconfirmed transactions, might as well jailbreak That is necessary for many things since Apple has designed the iOS system with large restrictions on what they can do compared with things like Android, Bada, Tizen, Meego. Those four are based on Linux, which is free and open software. |
