Title: Re: How long does it takes to confirm a transaction? Post by: cst on July 14, 2012, 05:47:49 PM As long as it takes to put it in a block by miner that solved it. Usually around 10 minutes.
Could take longer if you haven't paid a fee (no incentive for miners to process it). Title: Re: How long does it takes to confirm a transaction?

Coins need to be confirmed if you want to send them out. Title: Re: How long does it takes to confirm a transaction?

Presumably it's waiting for a confirmation or several before allowing spending, but I'm not very familiar with it.Title: Re: How long does it takes to confirm a transaction? Post by: deepceleron on July 15, 2012, 10:39:44 AM The answer is six Bitcoin transaction blocks. The official Bitcoin client considers newly received bitcoins to be "trustworthy" (and then marked as confirmed and added to the account balance) after the payment is included in a block, and then five further block chain blocks have been built upon the one containing the transaction. It takes an average of about 10 minutes for a new transaction block to be generated, so about an hour. However, with the current resilience and high mining difficulty, after a transaction has been included in the first block, there are few scenarios that would make the payment invalid or prevent the transaction from being permanently included in the block chain, and these would take a significant double-spend attack attempt by the sender.

No, the term "confirmed", and inclusion in the balance in the standard client, are after just 1 block.What the standard client does do is put a nice "V" icon near a 6-confirmations transaction. Ascribing magical properties to the 6-confirmations mark is archaic, it really depends on the nature of the transaction. 2 is enough for almost all transactions. |
