This kinda has to be a scam, since the poster has no way to know who actually sent the bitcoins...

huh? whoever sends them should probably send me a confirmation...

huh? I made the original linked post...did you even look at it?

I read your post "first one to send .01BTC to the address in my sig", but you have no way to know who that is.

[Luke-Jr]

Except there's no way for people to prove they sent bitcoins to someone...

When someone wants to buy something, they send you their shipping address, then you give them a bitcoin address to pay.
The only way to know what was paid for, is to provide a unique address for each payment (or at least person)...

At this point, I'm guessing maybe you're just new? Maybe reading these pages will help: Address reuse and From address

Slow down there, cowboy. This would have been a transaction for $4 and you come out of nowhere suggesting its a scam. Then you just become a pain in the ass. Stop trolling. With all due respect, don't comment on my posts if you only have something stupid to say.

I'm suggesting it's a scam because there is no way for you to fulfil your end of the bargain when two people claim to have paid for it, but only one actually sent you bitcoins.

Edit: unless you're prepared to mail 2*number-of-people-claiming-they-paid coins...

[miffman]

Dude, calm down lol. The person who sent the coins sends him a signed message with the address and that's it. Problem solved.

[Luke-Jr]

Dude, calm down lol. The person who sent the coins sends him a signed message with the address and that's it. Problem solved.

There are only signed messages proving you are the receiver, nothing for proving you're the sender.

I can send coins to you and sign a message with my address. 

Maybe I should stop feeding the troll

Are we talking about the same type of address here?  lol. You will see my address in your transactions. Then I'll sign a message.  I proved that I own the address's private key.


Aaand I'm done feeding lol.

[smoothie]

So funny how Luke-jr wants to make this out to be a big deal when really he should have done this with Butterfly Labs. We all know how that turned out. lol

The only address on the transaction would be my address.
(And maybe a change address for the wallet controlling the funds, but that doesn't identify a sender either.)

lol, it's hard to argue with that, but perhaps instead of being a dick, you might take a minute to educate people -- in particular, why they can't assume that someone signing with the address in an output referenced by the input was the sender.

[qwk]

By the way, I'm the person who wrote the sign message functionality you're talking about...

Seriously though, if I send 1 BTC from my wallet to your address, and then I send you a message
"I sent 1 BTC from my address 1aaa to your address 1bbb, here's the link to transaction txccc"
and I sign that message with address 1aaa,
how in the world does that not prove that I actually sent you that 1 BTC?

This thread has done its job. Everyone can kindly stfu *cough... luke-jr...cough*

Because that output has nothing to do with the transaction you sent me.
If it doesn't coincidentally happen to be an address I own, I cannot sign a message with it.
On the other hand, someone else can sign a message with it.

You didn't send 1 BTC from your address 1aaa to  my address 1bbb. You sent 1 BTC to my address 1bbb - there is no "from address" at all.

For example, you can't sign it if you sent the bitcoins from Coinbase or an exchange account, or through a mixer -- but someone else can.

Don't you just love how moronic Luke-Jr's hacker is, to assume the sender will choose not to spend their own goddamn, exclusively controlled private key so they cannot sign their own goddamn BTC messages with it. How much do we all want to bet that Luke-Jr's hacker assumes that healthy bitcoiners are too stupid to breathe without someone screaming BREATHE! at them?

The sender shouldn't need to know what a private key is. Nor did he mention upfront the buyer would need to abuse the sign message function for something it was never intended for, or even that he was relying on a bunch of broken assumptions ("from address" bs).

You seem like a smart dude.. can you explain to me like I am a full blown retard why the op has a problem. If I sent to him can I not easily prove it by sending the transaction details? If he doubted that I sent the coin I could always log back in and send .00001. Why would signing a transaction to the op not prove that I sent the coin?

Luke-Jr's moronic hacker continues, can't even remember his own encouraging of others to "do things unsafe", such as not learning what one of the fundamental elements of bitcoin is.

The transaction details are public - any random Joe could see it and claim they sent it.
How would you sending .00001 BTC prove you sent the initial 0.01 BTC? It wouldn't.
People don't sign transactions, wallets do - and there is no reason one should ever assume there is a 1:1 relation between people and wallets.

The users of cars don't know how engines work.
The users of air conditioning don't know how air compressors work.
The users of airplanes don't know how the navigational computers work.
The users of cows don't know how their DNA works.
Why should the users of Bitcoin be expected to know how its scripting works?

Luke-Jr's moron hacker continues... we all know Luke is way too fucking intelligent to make a false analogy that equates to people "shouldn't need to know what..." an engine, an air compressor, a navigational computer, or DNA "...is".

We get it dude, in your world, people "shouldn't need to know" anything about anything and be willfully ignorant instead. Now take your own medicine and enjoy being on my ignore list.

There is no way to prove a transaction came from a given wallet.
Also, wallets may have many users, not just a single owner.
