Title: Security Fast Payments Against Double Spends? Post by: Bitcoinm on May 02, 2013, 09:34:49 AM Is there any accepted method of securing a payment without waiting for confirmations? Is there a certain amount of time one could weight before crediting someone's account with Bitcoins (received through the network without confirmations) that would lower the risk of a double spend?

he more confirmations the better Title: Re: Security Fast Payments Against Double Spends? Post by: CIYAM on May 02, 2013, 09:48:11 AM I think a "green address" could be what you are looking for: https://en.bitcoin.it/wiki/Green_address (which AFAICT is limited to usage on Gox).
Title: Re: Security Fast Payments Against Double Spends? Post by: Herbert on May 02, 2013, 09:56:14 AM You could reduce the risk of double-spend attempts by actively distributing/resending the received transaction to as many nodes as possible. This makes it hard for the attacker to have success with a double-spend transaction as most clients should already know the first tx.
But this will not help on all attack vectors. Title: Re: Security Fast Payments Against Double Spends? Post by: TierNolan on May 02, 2013, 12:23:44 PM Is not forwarding the transaction really that much of a protection. Presumably, a double spender would have direct connections to miners.
