Instawallet is available also in HTML5 version for mobile devices, with the option to create an Instawallet Passbook on your iPhone (new feature of iOS 6).
PS: it still shows up twice in the poll list

Please add paytunia (e-wallet for web , iOS and Android) : I would like to vote for it although the meaning of the poll is limited by not allowing multiple choices

Great idea, I am seeding with my 2Mb. Just a suggestion: I would love to be notified when new torrent is created so I won't be seeding obsolete one. Could someone create a mailing list for that purpose?
+1 and many thanks to jgarzick for this useful development |

That's not a safe assumption to make when customers are the one taking the risk, possibly with a lot of money.
Coming from you it's kind of a really weird thing to say. You do sell 1000 BTC casascius gold coins right ? Yep, mainly because those who have bought my coins likely feel they have adequate recourse against me, and if their BTC were to disappear, there is exactly one person whose ass to kick. I have helped to mitigate their risk by sharing my personal information and offering to cooperate with any reasonable steps to verify anything anybody wants. You are welcome to disregard my input, as I don't mean it to be critical. Given the fee for a typical bankwire, I'd expect to see amounts much larger than 100€, certainly amounts worth stealing. I am simply recommending that you take steps to mitigate the risk of a MITM changing the comment field on a bankwire for his own benefit and not assuming it can never happen. Your concern is valid but has been addressed in our risk analysis before launching the service: we have capped the maximum amount to 100 € per day per bank account. Given the instawire sales flow seen by any given bank and the risk for the job security of a bank employee engaging in this kind of fraud, we consider the risk acceptable at this point. |

We have seen many examples where so called secure systems have been hacked. All it takes is one disgruntled employee.
To suggest that we would be careless enough to set up operations where "all it takes is one disgruntled employee" is simply insulting. If you propagate the notion that nobody can run a secure service on the Internet (meaning something other than a one-man shop) then you are playing in the hands of the incumbent players (banks). Additionally, the damage caused by accepting double-spent coins from a compromised BCCAPI server can be greater than whatever amount is stored in a hosted wallet. |

Well, of course I respectfully disagree.
SPV clients like Bitcoin Wallet can be instant-on. They are not today because the programming involved is tricky and not completed yet. But we'll get there eventually. I already find Bitcoin Wallet to catch up plenty fast enough if I enable the "sync on power" option, I think in future Andreas will make this option on by default so all users benefit. It means typically the client is only a few hours behind. And of course you can spend without being fully caught up to the chain head.
The primary remaining issues are reliability (if you connect to an overloaded peer sync can be very slow), storage costs (this can be solved quite easily), and bandwidth consumption, the fix for which is largely implemented by Matt and just needs review+merge+people to upgrade.
Running SPV on a phone is by far the hardest solution to make work well. It is also theoretically the best in terms of security, privacy and how closely it matches Satoshis vision of a truly P2P system. I think once the remaining performance problems are solved there won't be much incentive to use other types of wallet.
Any solution which involves keys being stored on the server is a non-starter for me. There have been too many cases of wallets hosted by third parties getting hacked. Not to mention the legal issues.
For me the Schildbach-Client was a no go for its heavy data usage. How can this theoretically be brought down to some one digit MB per month? I see the privacy benefits now but what else would put the Schildbach client ahead of the Spinner approach? (Sure, paytunia is no option. I fully agree on that.) I fail to see why a BCCAPI spinner would be an option (the servers can be compromised and lead you to accept double-spent coins) and why paytunia would not (our servers have never been hacked and we are a registered business). To make bitcoin grow stronger entails accepting diversity in design architecture and implementations. I will not issue any definitive opinion on any implementation until bitcoin reaches mass adoption. |

Jan and Goonie deserve a lot of respect for their developments. However, payment speed is of the essence while on the go, so I don't think (after careful testing) that mobile apps that hold keys or block headers in the device are suitable for widespread usage, going forward. Paytunia mobile brings the benefits of instant on and faster response time. We (paymium, of which I am a co-founder) released an HTML 5 version of paytunia.com (namely m.paytunia.com) to complement our paytunia app on Google play and to make sure iPhone lovers can use it too (since the iOS paytunia app got kicked out of the AppStore by Apple). A shortcut on the mobile desktop is all it takes to have the same experience as an app. Keys are strored securely on our servers and the block chain is always up to date ("instant on" applications). Same is true for our Instawallet app (check out the new home page of instawallet. The number of active users of our services is around 20 000 and ramping up fast. |

Merci beaucoup pour vos réponses. Je vais faire la mise à jour d'autant plus que je suis rassuré quant à mon wallet.
Par contre je ne comprends toujours pas comment trouver mon portefeuille sur un autre ordi, dans la mesure où je n'ai pas vu de système avec login et mot de passe ?!! je suppose qu'une adresse ne suffit pas pour s'identifier ?!!
Je me rencarde sur paytunia de ce pas !
Merci encore pour votre aide.
En effet, le client officiel est résident sur un ordi avec son fichier wallet (le trousseau de clés). On peut copier le fichier wallet sur un autre ordi et l'importer dans le wallet de l'autre ordi mais ça n'est pas très pratique. De plus, si tu ne t'en sers pas pendant plusieurs jours, le client officiel devra charger pas mal de blocs (ceux qui ont été créés depuis la dernière utilisation) avant de te montrer les dernières transactions que tu as pu recevoir entre temps. C'est tout l'intérêt d'un service comme paytunia.com qui héberge le wallet pour toi: tu peux y accéder instantanément depuis n'importe quel ordi (avc login + mdp pas trop simple) ou device mobile et il est toujours à jour. |

Précision: la mise à jour est sans risque pour ton wallet, donc tu retrouveras le même solde de bitcoin affiché par ton client après la màj.
La version 0.7 apporte un vrai progrès, notamment la possibilité de signer des messages avec une clé du wallet. Il a aussi des améliorations pour le réseau bitcoin (meilleure résistance aux DoS) donc une mise à jour à faire asap.
Cependant, je pense qu'il est beaucoup plus simple et plus rapide d'utiliser un e-wallet paytunia: toujours à jour (grâce au serveur qui héberge la chaîne de blocs) et disponible de partout (mobile et web, depuis n'importe quel nombre de devises).
L'appli mobile paytunia est dispo pour Android (Google Play) et les utilisateurs d'iPhone peuvent accéder à paytunia avec leur navigateur mobile (Safari ou autre) en tapant m.paytunia.com

Easy as pie, if we use a combination of smart-phone technology. So the vendor has a unique, generated QR code containing an address and the amount of the sale on a screen that you use an app to scan and hit 'pay'. Bingo.
The Blockchain.info wallet already has this functionality. Both vendor and customer need no additional hardware. People just need to start experimenting with using bitcoins. The current tools for experimentation are already there for the average person. With BitInstant they can buy $40 worth of coins at 7-11 and start playing with it. As they start playing with it they will get more competent; just like they are more competent with online banking, email, etc. Both buyers and sellers can use also the paytunia wallet to send/receive coins on their smartphone (app on Google play or html5 version of paytunia.com for iPhones). Buyers can get bitcoins for euros fast using instawire. |

Paytunia app for Android is the simplest and fastest (PIN code can be set optionnally)
Too bad it's not on the list.

I love the new design of the home page. And the fact that it has NEVER been hacked.
Stephan, Arsy and davout you are doing a great job with Instawallet.

One thing is kind of scary is that a rogue bank employee who knows about bitcoin could perform a low-tech meatspace MITM attack and insert his own address. By the time it was discovered it would be too late.
I highly doubt there is any manual intervention in transfers made from web interfaces, and even if there was, I think the risk is pretty equivalent to having your transfer maliciously re-routed to a different IBAN. Whether or not there is is highly dependent on the bank and their procedures. None of us really knows for sure, but finding out the hard way will be really expensive for somebody. I know I'm a little bit prudish, but then again, I haven't lost money with Zhou Tong, Pirate, or ever had a wallet stolen, or funds in a website that got hacked. I sent a wire out recently and, after clearly verifying that the amount was x, it went through for 10x, and then I had to start sounding the alarm bells pointing out that somebody somewhere screwed up. So clearly, at some places, some things are done manually. In that case, the full 10x hit the recipient's bank account, and then they were able to get the destination bank to send 9x of it back. Imagine your bank wire gets manipulated by a clipboard BTC-address replacer because some step along the way involves copy and paste on a computer that caught malware. Just sayin'! Come on ! Even in the very unlikely situation were they can alter the content of an online wire transfer, bank employees would not risk losing their job for a few BTC (each bank will only process a fraction of the traffic and it would not take long before we receive complaints). Then again, I can get struck by lightning twice tomorrow. |

Labor based value theory has been replaced by supply and demand since 20th century, and it has its reason.
And that reason is the industrial revolution, and the realization of the fact that human labor is relatively worthless in comparison to resources and capital. The law of supply and demand applies only in an ideal world of price setting; In the real world trades are twisted by a thing called "bargaining power", the result of regulatory capture, accumulation of capital, cartels, etc.. |

Ultimately, I believe, that the BTC community must transform from a cloistered technology community to that of a customer service focused business model; which puts the average consumers needs as the first priority.
I think this is very true - and I don't think governments have anything to worry about Bitcoin when it comes to that (as average consumers are already happy to give out all of their personal information to use credit cards anyway). I have a hard time envisioning most people I know managing a bootable truecrypt drive just to protect their Bitcoin wallet. Some standardized, easy and safe way must be devised before the "masses" will even give it a try. +1 on everything you wrote in this thread However, may I suggest you try our Paytunia wallet (with a Yubikey as our optional second factor of authentication) : that's a lot easier and very secure for any amount that it is reasonable to hold in a wallet (ie the amount of cash people carry around in general). Any amount above and beyond that qualifies as savings and should be held in a paperwallet imho. |

Ce livre s'adresse t-il qu'aux débutants?
AMHA, j'ai essayé d'être clair et accessible pour les newbies mais le livre convient aussi à ceux qui connaissent déjà et veulent approfondir la question.. |

Et on peut pas l'acheter avec des bitcoins ?  Il faudrait que j'en stocke quelques ex mais il y aura des frais d'expédition plus élevé que en direct avec l'impression à la demande par lulu (PM si ça t'intéresse quand même). Donc tant que lulu n'accepte pas les bitcoins,ça n'est pas optimal. Quand un éditeur sortira une édition papier et en imprimera plusieurs milliers d'ex ce sera différent: je pourrai les proposer en bitcoin sur mon site. J'y travaille mais ça ne sera pas avant plusieurs mois. Je viens de publier "Bitcoin Book" un livre de référence sur bitcoin en français, sous licence libre. Il est disponible sur lulu.com à 9,50€ , prix de fabrication, et s'adresse à tous ceux qui veulent comprendre le comment et le pourquoi de bitcoin. "Prix de fabrication"? Donc tu ne cherches pas à faire de profit avec ce livre? Dois-je en conclure que la version électronique est disponible gratuitement? Non, prix de fabrication pour que la version papier soit la moins chère possible: je touche zéro. Par contre, sur un eBook, je touche 1 € parce qu'un prix de vente à 1.90 € me semble TRES abordable.. EDIT: vérification faite, je touche aussi un euro sur l'édition papier. Mais de toute façon, à ce prix là, il faudrait que j'en vende des camions pour arriver au smic horaire.. |
