"The sky is falling!"

http://arstechnica.com/security/2014/06/bitcoin-security-guarantee-shattered-by-anonymous-miner-with-51-network-power/

old news of falling skies!

Not so much, GHash has broken the 50% barrier for sustained periods of time. The old news was they were a threat to but promised never to grow that much. Remember the public statements from them and putting a halt to independent miners joining? The unwritten news is they lied through their teeth and continued to add hashing power to their private stash. You do recall they were already caught once performing a double spend attack, correct? It is new news, a current problem if they continue unchecked.

Every pool has broken the 50% barrier every block. If you don't get the next block, then you're still at 50% for two blocks. On a daily average, Ghash never got over 50% of the network. On a 160 moving average, GHash.IO might have just touched 50% once for an hour or so.

Short answer - no, GHash.IO hasn't "broken the 50% barrier". I'd be more worried abut the fact it even got to 40% of the network. It tells me that many - maybe most - miners are very short sighted.

Im guessing the real short answer is You can type but cannot read

http://www.cryptocoinsnews.com/news/bitcoin-mining-pool-ghash-io-is-unapologetic-risk-theoretical-51-attack

You should try it or you are self proving your theory of short sight

I have no idea what you mean. What does that article have to do with anything I wrote?
