Logical fallacy.  Those statements are not equivilant.  Your 'sensible' person would have to ban cars, not ban speeding.  Like speeding, murder is already illegal regardless of the tool employed.

Premature.

Two samples have been claimed, while five remain.

I can't really do that.  I can only put my real return address on the outer envelope.  The sample will come in a small envelope inside a regular mailing envelope.

Send me a PM with your address, please.

I'll need a PM with your mailing address, please.

And that makes my fifth post, so I should be able to read those PM's soon as well.

Please post your home city, so that I can track that as well.

I don't know because I don't have a HE washer.  Are you talking about a frontloader?


Since you are the first to show any interest, sure.

I'll edit the OP to reflect the changes.

I shall call this one, Formula #1.  This is an aggressive formula designed for hard to very hard water.  A mixed powder for low cost shipping, with no fillers.  Very concentrated, mildly toxic if ingested.  Keep away from children, seriously.

Thank you,

Your client will submit the transaction to all it's connected peers, which will each verify it against their own copy of the blockchain.  If they consider it valid, they will forward it to all of their connected peers, and so on.  Once they have seen a valid transaction that spends a particular set of coins, that peer will hang onto a copy of that transaction and reject any other transactions that it sees that tries to spend those coins again.  Thus, the best defense against a double spend with the regular client is simply having a few seconds advantage over any possible double spend attempt.  If you have an online store accepting bitcoins, it is too easy for an attacker to time the transactions, so it would help to use more sophisticated means of detection for online stores.  Brick-&-Mortor stores would have no problem, however, since timing the transactions while at a physical cash register is difficult by it's nature.  And Bitcoin aware Point-of-Sale systems have other tricks for reducing risk exposure here.

In a sense, yes.  The two transactions must race to cover as much of the bitcoin network as possible before the other takes over a majority of the mining nodes; because the transaction with the greater percentage of mining nodes is more likely to be included in a block, and thus become the officially correct transaction.  The other will be orphaned forever.


It's not portrayed to be instant in all cases, but it can be pretty close.  Credit cards aren't instant at all, as they can be reversed up to 45 days later; they just appear to be instant because of all the user identification required.  If you are willing to identify yourself using bitcoin, these same tricks could apply.
