It also shows SegWit can lead to blocks much larger than 2MB if needed. That said, people will continue to nitpick over why this block was so large despite its lack of transactions. Things like these always spark intriguing debates, that much is certain.

Additionally, it goes to show SW is a positive way to address bitcoin scalability. It is impossible to push that amount of transfers in a 1MB block.

Oh, it's actually bitcoin2x testnet, not bitcoin core testnet. That's very confusing actually. Oh sorry, I didn't notice that! I haven't got around using it yet so I didn't know.

This not working now. Note that the SSL certificate is self signed. Flavien 4 Loourr 2, 4 10 You can use mine, for now it's on a best effort basis host: A bitcoin daemon isn't exactly a replacement for blockchain.

Almost all Bitcoin wallets rely on Bitcoin Core in one way or another.

If you have a fairly powerful computer that is almost always online, you can help the network by running Bitcoin Core. You can also use Bitcoin Core as a very secure Bitcoin wallet. Check out his other work here. We previously collected donations to fund Bitcoin advertising efforts, but we no longer accept donations.

All of the exchanges have this common standard that 6 confirmations need to pass before it accepts your Bitcoins.

A regular double spend race is when you send out two competing transactions - one paying the merchant and one paying yourself say. In principle it's hit-and-miss as to which transaction wins though you can put larger fees onto the transaction to yourself to try and bias it in your favour.

Any client would be able to see the double spend taking place, and a single confirm is enough to prevent it. A Finney attack is when you mine a block but before you publish the block to the world you quickly try and spend some of the inputs elsewhere. Once you've spent the inputs you then release the mined block, which effectively makes the unconfirmed transaction void.

This attack requires mining resource and very fine timing. It's mostly thwarted by 1 confirm. He sends a transaction over the network and in private builds up an alternative blockchain with a competing transaction. You wait for n confirms, but as long as his chain is longer than the public chain he can at any point release his private chain to the public undoing your transaction.

The risks for the attack are that this attack is probabilistic - he can't know that his chain will be longer after n confirms, he just has to get lucky.

There's nothing magical about 6, it's just a number that was suggested early on. The problem with this attack, apart from the vast computational resources involved, is that while he's building up his private blockchain, he's not earning income from mining. So this attack is expensive and only worth it for large huge! I don't believe one has ever been performed in practice, even for small n. For that matter I'm not aware of any deliberate Finney attacks either.

Clients can occasionally see it, but they don't do anything about it. Bitcoin-Qt won't tell you if it sees a double-spend of one of your transactions. On a bitcoin level they can't do anything about it. But if it's a face-to-face transaction they can call the police, or clock you one, or whatever is appropriate given the situation ;. You're right though, clients should be better at reporting double spends in progress - especially if it involves one of your addresses.

Satoshi did some estimation And it can be automatized on clients Say, each time you buy a cheeseburger from a zero-confirmation accepting merchant, send a replacement tx with higher fee to miners which accept them Sometimes you will succeed.
