You may have noticed delays in notifications for confirmed payments today. Bitcoind was running fine and all, except for the rpcthread to handle the jsonrpc commands. So monitoring did not complain, and all 0-conf notifications went through. But notifications for confirmations > 0 were stuck since block 221370.
I restarted bitcoind and the system is now catching up on the missed notifications.
Sorry for any trouble :-(

SatoshiDice violates the "no flooding" and "financial transactions only, no information" rules. Bitcoin's solution is to block flooders. Miners filtering out floods is part of the system.
I fully agree on this! But for me it seems more like rulea of conduct which *should* be followed by consensus, but are not enforced in any way (unless miners really start skipping sdice transactions). Or is this somewhere defined in the protocol?

Well again, what you are currently doing is having them sign something self-evident.  All that signature proves is that "The owner of address X agrees with the following statement:  'I own address X'".  Instead, you should have them sign something like "The email address someone@email.com is the address that should be associated with username <username>".  I don't know exactly what you're having them authorize with their signature, but it should be explicit.

Okay, absolutely agree. I will change the message to sign like this:
Quote
"Player <player name> with payout address <bitcoin address> shall be linked to account <account name>."

Thank you  Smiley

For logging-in scenarios you are definitely right, however in this case this is a one-time action. This is not about loggin in, this is only to link an anonymous player to another account. This is only possible once in a players lifetime, so i think it is not really necessary to add a nonce or similar. Right?
189  Bitcoin / Development & Technical Discussion / Re: Best way to make user proof that he owns address? on: February 20, 2013, 11:05:19 PM
Following up on this discussion:
I have this now implemented on bitbattle.me where you can connect an existing anonymous player (only defined by a bitcoin address) to your user account. To obtain ownership of such an anonymous account you need to sign a message with the player's bitcoin address.

Sample link (you need to be logged in to see it): http://bitbattle.me/connectplayer/minnow/

Technically works fine, but I don't know yet what other clients besides the official one can actually do this. And documentation/instructions probably need to be improved, already received some questions how this should work :-)

Another small update:
Anonymous players now again can close their sessions with the old 30 seconds timeout. Registered players of course still can close their sessions without waiting!

Another small update:
Since closing a session is now only allowed for registered players: The 30 seconds waiting time until you can close a session is now removed - You can close your sessions without any waiting time Grin.

Okay, up and running with some major update - optional account registration!

  • The "Get started" page now contains a section for optional account creation.
  • If you are logged in you have a dropdown menu on your username (top right of navbar) with shortlinks the the dashboard(s) of your player. (Yes, you can have multiple players connected with your account)
  • If you are logged in, every player you create will automatically be linked to your account
  • You can link your existing anonymous player to your account. Click on the "connect to account" button in the player's dashbord and follow the instructions (You will have to sign a message with your payout bitcoin address to prove ownership).
  • It is no longer possible to close other player's sessions (You can only close sessions of your own player when you are logged in)
  • It is no longer possible to start or join a multiplayer session with other players. (You can only do this with your own player when you are logged in)
  • It is no longer possible to create multiple players with the same name. Existing duplicates have been renamed.

Note that for account creation no email confirmation is necessary, so you can also register with fake email. However in this case there is no possibility to help you in case you forgot your password.

Site will be down a few minutes for upgrading...
194  Economy / Gambling / Re: bitbattle.me - Instant bets, still accepting 0/unconfirmed! With Multiplayer! on: February 18, 2013, 09:54:26 PM
So, any suggestions how to prove ownership of an existing player if the sign message feature is not available to you?

Blockchain-wallet users have some control over what addresses to make a transaction *from*, so
maybe requesting a new bet be made from the anonymous account's payout-address might work.

Still wouldn't work for instawallet(and equiv.)-users...
Good point. I was actually surprised that blockchain wallet does not provide the sign message feature. I think I saw it there before... Anyway for now I will only implement automatic verification based on bitcoins sign message feature. Other ways need to be done manually.

PS: I'm not sure about that "same name" business. Do they really use exactly
the same name,  and your software didn't already prevent it? Or is it just about
"looking" the same as by use of certain unicode-chars that look similar to ascii-chars?
Funny enough in the "slim"-example the scammer used slightly different names, probably expecting that the same name would be rejected ;-) But the site allows to use exactly the same name, as long as as the payout address is different. There is only a unique constraint on the combination name + payout address.
Really should have added that unique constraint on the name in the beginning...

Anyway, will start rolling out the update in a few minutes!
195  Economy / Gambling / Re: bitbattle.me - Instant bets, still accepting 0/unconfirmed! With Multiplayer! on: February 18, 2013, 01:31:23 PM
Scammer alert!

It looks like some clever guy is creating players with the same name and same vanity bitcoin payout address like frequent players. Obviously he is hoping that you place your bets on the wrong player, resulting in all payouts going into scammers pocket.

I will update the site ASAP to force uniqueness of player names to prevent this issue. Until this is in place please double-check that you are using the correct player!

See http://bitbattle.me/player/slim/, http://bitbattle.me/player/slim-2/ and http://bitbattle.me/player/slim-3/ for an example...

Herbert, Lethn: if you see the exact places interface features that can be improved, please let me know (I see some of them too, but your feedback is precious). If you have any specific questions, please ask. We need to know what topics should be better explained. Thanks!

It's not really about the UI. I am missing the basic information, some kind of tutorial how the advertising system works.
197  Economy / Gambling / Re: bitbattle.me - Instant bets, still accepting 0/unconfirmed! With Multiplayer! on: February 17, 2013, 10:53:10 AM
Optional accounts feature is making good progress!

Basically there is one topic remaining: If you create an account you can connect your existing anonymous player with your account. But you need to prove that the anonymous account is really yours. Right now this is implemented using the "sign message" feature of bitcoin: You sign a message with the players payout address, if i can successfully verify the signature the player is connected with your account.
But this is only tested/working with the official bitcoin client. Not all clients support this feature, at least with blockchain.info wallet I did not find this functionality.

So, any suggestions how to prove ownership of an existing player if the sign message feature is not available to you?

I just thought I'd say this is a great idea for getting ads on your site without annoying the fuck out of people, keep it up, the only suggestions I could make about it is making the interface more user friendly and easier to understand, perhaps some tutorials are in order.

+1 I still only halfway understand how this whole thing is supposed to work  Grin

Hmm. I am not able to enter a text when creating an ad. The forms textarea is just not there  Huh (Using Chrome 24.0.1312.57 on Linux). Still it complains that text must not be empty  Cheesy

Edit: Disabling Adblock fixed it.
