Is there a shortcode or anyway i can add a widget for the blockchain latest transactions to appear on my html site?
I have a website and i want the latest bloc…
It is said that a Bitcoin miner attacker with enough CPU power to outrun the entire network is better off mining honest bitcoins – which is not correct since by creating a false block chain the attacker already wins the coinbase on the way, just like he would if he behave honestly.
Actually, an honest miner has all the incentive to defraud by adding to his block transactions that cancel his own ‘real’ transactions.
Or am I missing something?
EDIT- and maybe an answer
Let me give an example, lets say Alice owns a very big pool (big pools had known to create up to 6 blocks in a row), also Alice buys something from Bob for 1 bitcoins every 10 minutes.
Alice could try to do double spending of each of her payments (by passing the same bitcoins to herself) and use the second transactions in the block she is mining.
Note that this is all completely legit.
If the pool solves the proof-of-work, then her ‘real’ txs will be canceled – Bob can wait 10 minutes to see if the transaction gets confirmed or not, but it might not be enough in the case that there was a fork.
A owner of a big pool can try to create doublespends but he will win his btc back only in rare occasions when:
- there was a fork
- Bob didn’t check the fork, and didn’t wait enough time (e.g. 1 hour) to see if the transaction was confirmed
- The good that Alice bought is not associated with any physical address (so that Bob cannot find Alice and claim for his money).

Damn this Bitcoin thing really blows. I only doubled my money last year and it's only up 35% this year. I should be a billionaire by now!
What kind of investment is this? I started buying like 2 years ago. I can't believe I'm not able to quit my job yet.
v0.13.0) mempool size is currently 12k transactions as can be seen from:
tail -f ~/.bitcoin/debug.log
I find this number very surprising as I naively expected it to keep in line with the number of ‘Unmatched transaction’ as reported say by blockchain.info which currently shows 3k transactions.
What am I missing?
