[Gebruik GEEN PostNL als je verzekering wilt hebben, en je object betaald is in Bitcoins!]

Ik verkoop zo nu en dan fysieke munten, en in januari is de inhoud van een van mijn pakketen verdwenen. Na lang gedoe, uitleg, heen en weer bellen, en nog meer heen en weer bellen, krijg ik nu deze eindbeslissing te horen:

Geachte heer Van Voorden,
PostNL zal tot nader order, geen waardebepalingen in Bitcoins accepteren.
Klanten dienen daarom t.a.t. een factuur te overleggen met een inkoopwaarde, welke wordt uitgedrukt in de internationaal alom bekende valuta,
zoals bijvoorbeeld € of £ of $.
Ik kan u alleen op basis van gewicht schadeloos stellen,incl,verzendkosten is dat 64,30 euro

Dit is nadat ik een uitgebreide mail heb gestuurd die ze bij het handje neemt en door de transactie heen leidt, en duidelijk aangeeft wat de koers is op de verzenddatum (huidige koers erkennen ze sowieso niet). Inclusief screenshots en informatie. Ik ben nogal pissed Ik heb dus ook nog een aantal pakketjes onderweg waarvan ik dacht dat ze verzekerd zouden zijn, die dus nu volledig onverzekerd onderweg zijn. Lekker is dat -__-'

Bij deze dus een waarschuwing: Gebruik GEEN PostNL als je verzekering wilt hebben, en je object betaald is in Bitcoins!

[I require the buyer to put the link "www.is.gd/warning0" in the transaction message.]

Recently I've been the victim of a number of man-in-the-middle attacks. Here is an explanation of how they work:

Imagine a scammer contacting me to buy Bitcoins. At the same time the scammer gets into contact with someone else, let's call him Bob. The Scammer sells Bob bitcoins, or something else, let's say a coat.

The scammer then gives Bob my bank account number. Bob pays, thinking he's paying for a coat. I get Bob's money, thinking I've been paid for Bitcoins. Naturally, I send the scammer the requested Bitcoins.

Later, Bob doesn't get his coat, and file charges against me, because I received Bob's money. Meanwhile, the scammer is nowhere to be found.

This happened twice to me, at roughly the same time. I inquired with local law, and it turns out I had to refund the scammee, Bob.

Note that exchanges typically solve this problem by requiring you to verify your bank account beforehand. That's not really something I can do.
Discarded solutions are:

Asking for ID. They can be faked, or the request can be just as easily forwarded by the scammer.
Calling the person. This might work, but just a bit. So you have their phone number. What then?
Starting with small amounts. This might be helpful, but it's slow, and not really ideal.

The best solution I've been able to come up with is this: I require the buyer to put the link "www.is.gd/warning0" in the transaction message. The page behind the link explains that they should be talking to me, via my email, and explains the above scamming scenario. The scammer hopefully can't require Bob to put this in his transaction message, because Bob would wisen up when he reads the link.

I've not had any more MitM attacks since then, so so far it's been working. Suggestions are welcome.

Ik sprak net met Matthew van Bitcoin magazine. Ze gaan in de Barnes & Noble editie van Bitcoin Magazine (#3) een artikel over het Bitcoin symbool doen. Ze stellen voor om vanaf nu het nieuwe symbool, Ƀ, te gebruiken, die al in unicode zit en niet wordt gebruikt voor enige currency. Zie http://www.ecogex.com/bitcoin/ voor meer argumentatie.

Als je meedoet als bedrijf of individu, laat het me dan ff weten, dan geef ik dat door aan Matthew en voegt hij je toe aan deze lijst hier als supporter: https://docs.google.com/spreadsheet/ccc?key=0Ajtx05YrHtIydEFmWVVWQWpuYmwybExZY1A1d3Y0Z3c#gid=0

Edit: Hier een custom keyboard layout: ftp://bitcoinlayout:bitcoinlayout@forecast.student.utwente.nl/usinbtc.zip
US-international layout (wat de meeste mensen hebben), maar dan met Ƀ onder AltGr+B (of Ctrl+Alt+B).

Als er behoefte is aan andere layouts moet je het maar even zeggen.

[02:41:59 PM] Matthew N. Wright: We'll be releasing a new article in the Barnes and Noble first issue about the Bitcoin symbol and how it cannot work the way it is (it is incompatible with -anything- in the world right now), and showing everyone how to use the new recommended symbol (originally recommended by http://www.ecogex.com/bitcoin/ ). The symbol is Ƀ (U+0243)

This is an excerpt from the site: "Ƀ (U+0243) is a unicode character used as a "capitalized alternate symbol for the voiced bilabial fricative in Americanist phonetic notation". It is included in a lot of typefaces such as Arial, Times New Roman, Tahoma, Helvetica, Deja vu, Linux Biolinum, Linux Libertine, FreeSerif, Geneva, Gentium Plus, Microsoft sans serif, and many more..."

If I can get confirmation from you that you will adopt this standard symbol, I would like to list your name in the "supporters" column of https://docs.google.com/spreadsheet/ccc?key=0Ajtx05YrHtIydEFmWVVWQWpuYmwybExZY1A1d3Y0Z3c
[02:43:03 PM] Mqrius: Yeah, sure, I'll add it to my keyboard layout
[02:43:23 PM] Mqrius: What are these adoption tiers?
[02:45:10 PM] Matthew N. Wright: 1st means they're leading the pack
[02:45:15 PM] Matthew N. Wright: 2nd means they're going right after that
[02:45:17 PM] Matthew N. Wright: and 3rd means unsure
[02:45:39 PM] Mqrius: I'll take 1st
[02:46:02 PM] Mqrius: 's about time there was some decision about the logo
[02:46:35 PM] Mqrius: I don't like the colors much though :x
[02:46:44 PM] Matthew N. Wright: Nah, the colors are not required
[02:46:45 PM] Mqrius: http://www.ecogex.com/bitcoin/ They look depressing
[02:46:46 PM | Edited 02:46:49 PM] Matthew N. Wright: What's your email again?
[02:46:50 PM] Mqrius: Nuntius.Marii@Gmail.com
[02:48:15 PM] Mqrius: can/shall I spread this to people that may want to be on the list?
[02:48:24 PM] Matthew N. Wright: Yes!
[02:48:26 PM] Matthew N. Wright: Anyone!
[02:48:28 PM] Matthew N. Wright: Any businesses too!

Edit over de tiers:
1st = Front line
2nd = Ready to go when front line does
3rd = Need to see the effects of front line to decide
4th = Will do anything the "community" does

At the start of August I'll be in Sweden for two weeks (middle of nowhere, really. "Skillingaryd"). I would very much like to have some internet there… I was considering buying a Swedish prepaid SIM card with data, but I have no idea about what to buy, where to buy it, etc.

Can anyone make some suggestions? I'm open to other options as well.

Thanks

Has anyone heard of King Arthur's Gold?
KAG is one the first build'n'kill games in the world. It's a game about mining, building castles, destroying your enemies and collapsing their castle. It is a side-scrolling 2D action multiplayer war game with focus on building, constructing siege machines and intense PvP combat. Some inspirations for the game are Soldat, Minecraft, Dungeon Keeper & Ace of Spades. Currently available on Windows, Linux & MacOSX.


Basically, you build castles, walls, towers, siege weapons, and attack the other team's castles, walls, towers, etc. If you remove the support for a tower, the entire thing collapses. You can attack directly, try to build a huge sky-bridge, try to tunnel there, catapult yourself there, prevent others from getting to you with trapdoor'ed spike pits, bombs, arrows, chargestrikes, catapults, etc.

Anyway, it's fun. Multiplayer (64 players, anyone?), and free, although in the future there will be premium accounts getting more stuff.

Youtube link:



Anyway, they're currently looking at new payment options. I suggested bitcoin wherever I could (Google+, Facebook, their questionnaire), and at some point got into a long discussion about bitcoin on their IRC channel. (Basically whenever someone helps me on IRC, I suggest they post a bitcoin address so I can send them a few bitcents for their help. This has twice now led to some people learning about and installing bitcoin )

Anyway, a while later:

[17:15] <@Shadlington> Quick scan up
[17:15] <@Shadlington> Too much to read since I went afk
[17:15] <@Shadlington> But you were talking bitcoins?
[17:15] <@Shadlington> People keep banging on about them on the kag G+ page
[17:35] <@Shadlington> How easy is it to cash out bitcoins?
[17:35] <@Shadlington> And how easy is it to setup a payment system that accept them/
[17:35] <Ej> no idea, he didnt tell it
[17:35] <Ej> we were mainly asking about bitcoins farms
[17:35] <Ej> and losing your hardrive with key
[17:36] <@Shadlington> Yeah those are the two things that would affect my willingness to consider bitcoins for kag
[17:37] <@Shadlington> Anyways who was the guy that knew all about them/
[17:37] <Raron> Idk
[17:37] <@Shadlington> Might quiz him
[17:38] <@Shadlington> nick?
[17:39] <Ej> the guy is Mqrius
[17:40] <Ej> and he is here
[17:40] <Ej> but afking
[17:41] <Raron> how can you buy bitcoins anyway
[17:41] <@Shadlington> Mqrius, chat to me about bitcoins when you're back, if I'm here
[17:41] <@Shadlington> Or else just PM me on forums :p
[17:41] <@Shadlington> I am genuinely curious

[Electrum 0.40a Build 1MD5: b46efaa4e29e46903d050a9bdf9e90f7]

I will post my no-dependencies windows builds of the Electrum thin client in this thread. I will add a post every time I make a new build, and also update this post to reflect the newest version.

These builds should run without installing any python or gtk or whatever, i.e., they should Just Work™.
Note: For some reason, the builds won't work under windows XP. See BitcoinBug's version, that might work.
Also, the file is named incorrectly when downloading with internet explorer.

Electrum 0.40a Build 1
MD5: b46efaa4e29e46903d050a9bdf9e90f7

* 'create' and 'restore' commands are now distinct, so that it is possible to create offline wallets. https://en.bitcoin.it/wiki/Electrum#Offline_wallet
(* Support for remote wallets. (demo here: http://ecdsa.org/remote.php. Detailed explanation: https://bitcointalk.org/index.php?topic=65136.0) <- I did not compile this. Let me know if anyone is interested in having this.

------------------------------------------------------

Electrum 0.40a Build 1
MD5: 6e8397686422c1f7c829b5b35b1fc72d

* New Qt GUI
* If you want to use the old Gtk gui, type:

Code:

 python electrum --gui gtk

Also currently available is BitcoinBug's build packaged by Cameyo, this apparently does work on Windows XP.

Cameyo packaged version of Electrum v0.40a.
It's GUI only, no console window.

Electrum.v0.40a.Cameyo-minimal.exe
MD5: 930d6a8efa2ee8fdafc1ab1a21696724

------------------------------------------------------

0.39

* two options have been added, for selecting transaction input and change address: --changeaddr, --fromaddr  [patch by DiThi]
* The status bar displays 'synchronizing' when the client is connected to the server, but is still waiting for history updates. (until now it was not showing this information)
* If the user's server is down, the client remains able to download the list of active servers, by sending queries to a default list.

------------------------------------------------------

Electrum 0.38 Build 1
MD5: 04058ba44bc5129d790722f9103a7dac

* aliases and signed URIs (see http://ecdsa.org/bitcoin_URIs.html )
* 'signmessage' and 'verifymessage' commands, same syntax as in bitcoind
* 'eval' command, that evaluates a python statement. Use it to examine or modify the content of your wallet from the command line.
For more details, see the main thread.

------------------------------------------------------

Electrum 0.37 Build 1
MD5: b146d3253ce552998daf8b838782ff3a

* Bitcoin URIs can be passed to the client. To configure your browser, see http://ecdsa.org/bitcoin_URIs.html
v0.36:
* json protocol over http (still experimental)
* during wallet creation, a dialog proposes a list of active servers

------------------------------------------------------

Electrum 0.35 Build 1
MD5: f8a93a18387964769e13e14d7c4c7c22

* New 'import' command to add extra keypairs to your wallet. Example:

Code:

Electrum-0.35-Build1.exe.exe import 1MtQTsraWDcb7REUnVu8LS9hZswrLfWbH9:5KeCdRAkygEGfSzQ3ZNpQ2qE6PdEYCZ52S9Uq5DoBxkSgayX6ng

Note that you can export your keypairs in the same format using:

Code:

Electrum-0.35-Build1.exe addresses -k

* random selection of the default server on wallet creation
* bug fix: previous version was not correctly synchronized after creating new addresses

------------------------------------------------------

Electrum 0.34 Build 1
MD5: 499f71730a0eecc24efef8eab3e6531d

* "type 2" key derivation: bitcoin addresses can be generated without access to the main seed: synchronization between multiple instances of your wallet.
A wallet migration is required. Please refer to the release notes for explanations about the upgrade.[/quote]

------------------------------------------------------

Electrum 0.33 Build 1
MD5: 5ae1fbaa517ce217a83ce8fcdd3fc0be

*fix a bug that occurs when several transactions are unconfirmed at the same time.

------------------------------------------------------

Electrum 0.32 Build 1
MD5: 892e698b9bebfae16e993e0f77409073

Electrum 0.31 Build 1
MD5: a99cfe2461eb0af389df7fb07652340a

I took it upon myself to search for and contact the bitmarket.eu people directly, i.e., not via admin@bitmarket.eu.
I got a response from them today, 3 December 2011:

Hello,

First of all we're sorry for this situation. We understand that you and our other users who are in situation where their funds are blocked can get angry about it. We definitely would pay more attention to this, but there are few reasons why at the moment we don't. Biggest of these reasons is very simple - we were hoping that the site will pay for itself and our time they we invested in it (and we keep doing it, because it's hosted on a VPS server which costs us ~$40 /month). And now, when Bitcoin price has gone to record lows, we just have to work on other things to pay for our livings.

That being said we don't want to leave our users alone with this problem, and plan to do few things to aid this situation: - first of all, we'll invest some time, starting today, to straighten things for our users that have their funds blocked by malicious buyers/sellers. There are few dozens of these cases as I see now in our inbox, this should take no longer than few days. - second, I, as a developer of bitmarket.eu, plan to implement a simple mechanism that will automatically cancel a transaction and return funds to seller when the buyer doesn't respond. This should eliminate need for us to assist those cases, which in turn end up well for us as well as our users.

I hope that this explanation satisfies you. Should you have any more questions, feel free to ask.

That sounds good. It's also good to finally get a response.

PS: I may have threatened to release his personal information to a horde of angry users if he didn't respond. Seems to have worked

[bitcoin:pay:1MtGoxAddress1es89fwSTYR:5:MtGox deposit to account BTCurious]

A simple integration step that I think is missing in the combined toolset is a web-based protocol. (A "bitcoin:" version of the "mailto" link)

Imagine this situation:

You register for mtgox, and want to deposit some bitcoins. You go to the deposit page, fill in the amount you want to deposit. MtGox generates a bitcoin protocol link, for example:

bitcoin:pay:1MtGoxAddress1es89fwSTYR:5:MtGox deposit to account BTCurious

By clicking a button or the link, the data is forwarded by the browser. You have installed the default bitcoin client earlier, which registered the bitcoin protocol, so this is now sent the data.
The client asks you:

Do you want to pay 5 Bitcoins to 1MtGoxAddress1es89fwSTYR? Payment data: "MtGox deposit to account BTCurious"
Yes/No

You click yes, and it's payed. You never have to copy/paste any addresses. You can connect the protocol to your favourite walletmanager, be it the standard client, or your webbased wallet.

A client might also provide the ability to generate these links to send to your buddy who wants to pay you:
bitcoin:pay:1JohnDoeAddress1n4e3o1tnsuy:50:You still owe me a Block, dude!


I believe this would very much increase the userfriendliness of payment and address management.

I propose creating a standard for this protocol. It's open for suggestions, but my initial idea is:

For doing payments (webshops, deposits, inter-person payments)
bitcoin:pay:<address>:<amount>:<comment>

For saving an address in an addresslist (useful for miner payout addresses, green addresses)
bitcoin:address:<address>:<comment>

If you want to type the Bitcoin currency character easily, you can add it to your keyboard layout. I'd share my new layout, but I personally use the Colemak layout and no one is using that anyway, I guess.

You can download the Microsoft Keyboard Layout Creator (also works on windows 7) to edit it yourself.
If people let me know what keyboard layout they use, and what location for the ฿ is the most convenient, I might fix up some installers tomorrow.
