Topic: Double spending while spending bitcoin on stores - page 2. (Read 1777 times)
Would double spending cause the network to undo both spend attempts? That is how I thought I works, would someone correct me on this if I am wrong.
a time ago ... that the point.
with 0.8.6 perhaps.
with 0.9.0 = No, really no ...
Oh, maybe I kinda out of the loop here. Thanks for pointing it out, gonna try it again someday (For testing purpose only of course)with 0.8.6 perhaps.

Double spends are possible, but really hard to do because you would have to send both of them quickly and too two different parts of the network. Once a miner has seen a transaction it will reject any address that contains the same inputs.
I'm sure DannyHamilton or DeathAndTaxes can explain this a lot better. See this post by DeathAndTaxes for more information about sellers that accept 0 confirmation transactions.
Gonna check it, thanks! I'm sure DannyHamilton or DeathAndTaxes can explain this a lot better. See this post by DeathAndTaxes for more information about sellers that accept 0 confirmation transactions.

you can't double spend in an open environment ...
you can double-spend with a isolated bitcoin core server and local network ... and a wallet with "trusted IP" pointed on this server (to accept 0-confirmation transaction).
in real world, you can't have this ... even if you want.
Really? But I ever do double spending while my current transaction isn't confirmed because no fees a long time ago.. you can double-spend with a isolated bitcoin core server and local network ... and a wallet with "trusted IP" pointed on this server (to accept 0-confirmation transaction).
in real world, you can't have this ... even if you want.

Do you think it's possible and dangerous?
Because it needs around a minute to 2 hours to confirm a block, and there is no way to wait a confirmation while you on the queqe line.
Let just say they're "okay" with no current block confirmation and let you leave the store, but what if someone just sent a payment with no fees, make them not included and confirmed in the next block, Then after he leaves he quickly create a new transaction into his new wallet, make a double spending.
