Hi,

do you know the health impact fund? Maybe best described in this video?

How about a Bitcoin Donations Fund? Bitcoiners donate to it. Each month 10% of the collected funds get distributed to accepting charities based on their size (annual funds).
Charities would still have an incentive to be the first to register but also to stay with it in case people donate.

1943  Bitcoin / Bitcoin Discussion / Re: why isnt there a bitcoin app in the amazon app store? on: December 19, 2011, 03:49:12 PM
In general both the Schildbach Bitcoin Wallet and Bitcoin Spinner (as mentioned above) are open source. You are free to package it for the amazon market place. It simply isn't worth the hassle from the perspective of an Android developer to do so as it involves registering at amazon as a developer blablabla ... for no profit and barely any users actually using the app afterwards. Look at the Schildbach download count, divide it by 1000. That's what you can expect on amazon.

So for now I guess those few that really want it on the kindle should grab the apk from the web without using the store with its restrictions and legal implications.

I'm an android dev and compiling the Schildbach client is a no-brainer for me but the amazon legal fine print, possible fees etc. are nothing I have time for now.

cool site! bookmarked.

2 requests though for http://blockchain.info/unconfirmed-transactions
* on the map you show flags but not in the list. wouldn't it make sense the other way round? in the map the symbol could rather represent the order of magnitude of the transaction than the country which is clear by the location.
* please make the sound opt-in instead of opt-out. Took me 5 minutes to find the tab that was beeping.

I could put a link to the video but its in hebrew....

Please do. Pages in funny languages are also valuable references for those funny people that understand them.

Wie überprüfe ich denn des Stand des casascius-coins?
und wenn ich ihn mal "benutzen" will muss ich ihn kaputt machen oder?

Casacius-Coins kosten 1.8BTC bzw. 5$. Ich würde sie nur als Sammlerstück betrachten und nicht ausgeben. Wenn Du am Bitcoin-Treffen welche tauschen willst, dann geb ich Dir 2BTC für ne intakte Münze, aber Du kannst sie auch bei MtGox eintauschen. Dafür musst Du sie aber zerstören.

(Ich will niemandem empfehlen, eine Geldanlage in diesen Coins zu machen, weil Du letztlich niemals wissen kannst, ob der Macher nicht doch eine Kopie der Schlüssel behalten hat. Die Vorstellung, meinen Kindern mal eine 1,000,000€-Münze vermachen zu können, hat aber auch ihren Reiz Wink

The protocol supports multiple versions for the same transaction. 

Oh! Interesting! So I can broadcast several transactions that are in conflict and clients will not drop those that arrive later?
While at first I thought that sounded like facilitating double spending, it is actually pretty decent in order to detect double spendings Smiley

(I love bitcoin. Something to learn every day.)

ff said the certificate was issued by "StartCom" (like the stock browser and dolphin) but without a warning.

opera does not allow to get any details about the https certificate
1949  Bitcoin / Bitcoin Discussion / Re: android malware? (I get different invalid certificates when browsing bitcoin ... on: December 01, 2011, 09:13:31 PM
I would say it is some kind of DNS poisoning. My A/B-test with dolphin was more of an A/A-test as my brother told me so I tried firefox as well and there I get no certificate warning. On the other hand in ff for android there is no way to see the certificate details neither so I'm a bit nervous. Installing Opera atm.
1950  Bitcoin / Bitcoin Discussion / Re: Transaction fee? on: December 01, 2011, 04:25:38 PM
The Bitcoin network has no idea what the useful portion of the transaction size is.  It only knows a transaction has x as the total input and y as the total output( including the unidentified change address).  The fee is x -y.

I don't understand. Ok, there is no "<fee>xy BTC</fee>" in the block. Maybe. Still the fee exists and clients and miners can calculate it.
Right now
the miner can decide what to do with any coins left over from all the transactions in "his" block, including the generation "transaction".
My suggestion was that
the miner can decide what to do with 1% of the coins left over from all the transactions in "his" and all prior blocks, including the generation "transaction". Within each transaction, the input must be bigger than the output by a magnitude of 20uBTC per kB the transaction takes in raw format.
1951  Bitcoin / Bitcoin Discussion / Re: Transaction fee? on: December 01, 2011, 03:26:25 PM
The exact time depends on the value of each address and time.

The formula the client uses is:

Code:
priority = sum(input_value_in_base_units * input_age)/size_in_bytes

If priority is >57,600 there is no transaction fee.

This is an interesting detail for me. Is there a discussion going on somewhere on how to develop on this mechanism? How does the fee count into the equation?

For the network it is bad to have too many transactions and this priority is an effective flood protection ... to a certain extent. With 1M BTC I can still produce 1M transactions per day which is about 50MB  (if I don't do weird 1000 addresses to 1000 addresses transactions which might cost the basic fee) per day. For free.

Wouldn't it make sense to completely ignore the input value and take the transaction size for a fixed fee? From the user perspective we want to charge for the service which does not depend on the wealth being transferred but only on the effort to note down some numbers.

Each kB (which is about 2 transactions) will get stored forever on at least 10k computers and not only on the one miner's computer that accept it in the first place. 1kB*10k equals to something like 10MB web space which in turn would justify to charge 0.001$ or 0.0003BTC wouldn't it?
(A TB costs about 20BTC. A kB therefore costs 0.00002BTC=20uBTC.)
Which arguments go against such a fixed fee? With the 50BTC reward we have now, you can easily make it 2uBTC with both a flood-protection effect and a long time model removing all this uncertainty about fees.

Although I myself promoted Bitcoin as a tool for micropayment, it is and will never be fit to be that on a large scale. With 10uBTC fee for my transactions I could still do pretty small payments.

Continuing on that thought why should only the miner who packs a ridiculously large transaction into the block chain be rewarded while all miners have to live with it? I suggest to add all fees to a fee pool in the block chain and miners are allowed to reclaim 1% of that fee pool. Miners would then have an incentive to not build on chains containing blocks like this one. 330kB for 46 transactions and 0.24BTC fee mostly from old clients 0.02BTC as I suppose.

with the dolphin browser I get the same certificate warning.
1953  Bitcoin / Bitcoin Discussion / Re: android malware? (I get different invalid certificates when browsing bitcoin ... on: December 01, 2011, 01:23:53 PM
actually the problem first occurred when i tried to show bitcoin to a friend on tuesday (3g)
and persists today here at home (plane mode with wifi).

I "$ adb shell"ed into my phone and checked the ip via ping but this looked fine. Next I try an alternative browser.

I was able to send my coins out of the schildbach client to my desktop and will further investigate. well ... my brother will. said something about root certificate voodoo on some router something.
1955  Bitcoin / Bitcoin Discussion / Re: instawallet.org compromised? on: December 01, 2011, 12:16:46 PM
this is getting interesting. the forum has the same problem. non-trusted issuer StartCom something. So a malware in the wild?
How do i debug this?
I have the Schildbach client on my phone and i'm somehow concerned now.

Somehow I don't think that the google market was the vector here. If the Schildbach wallet was compromised there would be no need to mess around with certificates. I am very paranoid about trusting bitcoin apps (see this forum).
I recently installed 40 apps around flash cards, so yes, I do have many apps but as soon as it is about bitcoin I don't touch it.

Hi,

when I try to visit instawallet.org via my android phone I get a certificate warning and the certificate I get presented dates to 2006-09-17 while the one I see when I go there with my desktop browser dates to something this year.

Strangely searching for instawallet here on the forum returned zero results!?!?

Any ideas anybody?

hmm   ich weiß nicht ob mann bitcoin als religion angeben kann Wink

Der Vorschlag kam schon öfters. Mit welchem Argument sollte man denn nicht können? Gut wär's. Religionen verbieten sich in den meisten Ländern schlecht. Andererseits wäre eine Religion in anderen Ländern vielleicht ein größeres Problem als eine alternative Währung Smiley
