What's the story with all you guys offering btc here for that app, was that all hot air and you are now sitting back home smiling because you got the app for free?


No offense to yourself, nor to Andreas; but his app never met my own bounty requirements.  I've conversed with him about this in the past via email, and have received some interest in finishing those requirements; but apparently mine are too few to be of significant interest.

Could you be more precise about your requirements??
The last post surprised me a bit as my shildbach-transactions always had problems. Once I sent 1BTC and it only got sent after sending another 0.005BTC. Now I have 1BTC stuck since weeks and sending another 0.005BTC went through without breaking the other BTC loose like last time. A permanent grayed out transaction.
Therefore my requirements would be some way to backup my wallet but if all txns get through, I'm happy with it.

This is often caused by the inconsistent nodes the android client connects to, it was limited to 6 nodes for concurrent connection issues that android had (I might be wrong though, correct me Goonie :/)

I've too have been testing/forking the codebase and been using it September, it has little issues. I highly recommend you connect to a dedicated back-up node or your bitcoind on a vps or something ( this is my setup ).

But if I need a connection to my bitcoinD, what's the point in having Schildbach's app? I can already remote control bitcoinD with other apps that are far less code.

Why? I think the answer is obvious but single point of failure is a good one. by connecting to other known well connected nodes such as your own, or https://en.bitcoin.it/wiki/Fallback_Nodes you eliminate this risk, not to mention it's a full feature client and makes you part of the network.

*due to the limited number of connections (6) you might not able to get the "freshest" data on the network thus you have spotting tx confirmations and etc.
the satoshi and any bitcoin client can suffer from the same problem from this low connectivity.

ok, fine, but with a sample of 6 peers, the Schildbach-Client could also just drop those with the stalest data and connect to fresher ones, couldn't it? How come there are so many stale clients that 6 peers are not enough to get the head of the block chain??

I have been in the past on this very topic thread, but much deeper.  Basicly everything has been implimented except for off network transactions, and direct (ad hoc wifi) or semi-direct (two android phones using an open wifi access point as a bridge) client connections to both trade transaction data and blocks.  The later could be accomplished by utilizing broadcast/multicast features of wifi & a "piratebox" as the bridge (http://wiki.daviddarts.com/PirateBox) and Andreas has created another program for networking android devices into a complex screen that uses multicast to coordinate, so I know it's within his abilities to do so.  I just think that he doesn't consider off-network ad-hoc transactions to be a worthwhile goal.  I wan't to be able to use my phone wallet, for in person transactions, even during a power/network outage. (or beyond wireless service range, camping perhaps?)  Otherwise a remote control app for my home bitcoind is just as powerful.  If I can't use it to buy half-priced milk at the corner store because the store owner doesn't have power to run his refrigeration units (or his register to process credit card transactions) than it's not "cashlike".

"The powers of financial capitalism had another far-reaching aim, nothing less than to create a world system of financial control in private hands able to dominate the political system of each country and the economy of the world as a whole. This system was to be controlled in a feudalist fashion by the central banks of the world acting in concert, by secret agreements arrived at in frequent meetings and conferences. The apex of the systems was to be the Bank for International Settlements in Basel, Switzerland, a private bank owned and controlled by the world's central banks which were themselves private corporations. Each central bank...sought to dominate its government by its ability to control Treasury loans, to manipulate foreign exchanges, to influence the level of economic activity in the country, and to influence cooperative politicians by subsequent economic rewards in the business world."

Good luck preventing him from double spending. If all shops accept offline transactions, he walks from door to door spending the same coins over and over again restoring his backup in between. I doubt BTC will be any useful offline.

The risk of a double spend isn't always of greatest concern.  It would still be quite technically difficult to double spend even in this situation, kinda stupid to risk it for half priced milk.

Some of those bounties have mutually exclusive goals, so they cannot all be claimed for the same client.

Sorry in advance for the necropost. It took ages until this got settled.

My little 20 BTC bounty is being paid now, I sent 15 to BCCAPI and will send at least the remaining 5 to BitcoinSpinner when I find a donation address.

What's the story with all you guys offering btc here for that app, was that all hot air and you are now sitting back home smiling because you got the app for free?

The bounty was obviously not intended for "lol I meet the nonexistent specification when there is good weather" crapware. I need software that I can actually use to introduce people to Bitcoin. The kinds of errors, crashes and broken designs (Backup?!) the first Android clients produced were unacceptable. The Schildbach wallet has failed me on many occasions, and did destroy money on a newcomer's phone. I needed Nandroid backups to get coins back multiple times, those with locked-down phones were not so lucky.

BitcoinSpinner using BCCAPI was the first project that delivered and worked reliably enough to be used, so I can announce it as my personal winner. Strange as it is in terms of block chain management, it does what is asked of it.

That said, I encourage everyone to join in and support whichever client they prefer. A few BTC does not seem much, but if a lot of people donate, it adds up and supports good software and thus Bitcoin.

These days the Schildbach wallet works pretty well, but I don't think the full bounty was ever claimed. This thread is a great example of why bounties are a bad idea, actually. I usually tell people not to post bounties when I see them these days and so far nobody has ever disagreed with me.
