Post by: BookLover on December 25, 2014, 06:20:46 PM will be detected as double spend? Yes, just wait for a couple of confirmations.will he knows that he pays for 1 person? I'm not sure what your asking here. Do you mean can he only pay one person with the same coins (and not double spend)? If so the answer is yes.will transaction will be safe for me? i mean buyer cant cancel the transaction Yes it's safe, once you have the coins the buyer cannot reverse the transaction.Title: Re: how do buyer know double spend?

Title: Re: how do buyer know double spend? Post by: KIRAZ on December 25, 2014, 07:47:27 PM In the case of double spend one transaction will automatically be drooped by the network and yes it's bad.
The cases to happening it is pretty low or else to be safe you can always wait for a confirmation. Title: Re: how do buyer know double spend? Post by: ranochigo on December 26, 2014, 08:18:03 AM will the payment simultaneously rejected? One of the transaction will be confirmed and the other will be dropped by the network. You can never have both of the transaction getting confirmed. Double spending is relatively difficult but it is possible.To prevent double spending, one confirmation is mostly enough for small transactions, for big transactions, 6 confirmations would be enough as anyone with less than 51% of the hashrate have very less chance of double spending the transaction.Title: Re: how do buyer know double spend? Post by: crazyearner on January 02, 2015, 12:39:48 PM If you get a double spend that can and still happens on some sites. One payment will get accepted and one will get rejected and never confirm some sites who don't have protection from this often will get double spends sent to them using some sort of scrypt site accepts both payments however one will only ever get their and the double spend will never make it. Have been on a few messed up sites in the past getting paid double for my work on some pools not sure how this happened maybe the double spend rule happened but was able to cash them out but was kind enough to report it to the pool owner and pay the exta back unlike many who didn't and the pool soon closed after.

Post by: muhrohmat on January 12, 2015, 10:18:03 AM you in the btc adress are able to see the ocured in blockchain and if its going to be confimed by that address in case of double spend i just thought it was for over 51% of possession of PHs of the total mined by pools like ghash.io

The best thing like people suggested is to wait for the deposit to have 2 confirmations atleast . After that it is assured that it is not a double spend. |
