Title: [2014-06-25] Losing to win Post by: erono on June 25, 2014, 03:39:36 AM http://www.economist.com/blogs/schumpeter/2014/06/bitcoin
MOST elections, if you win more than half of the votes, you call the shots. In the land of Bitcoin things are a bit more complicated, as events last week showed: although a huge coalition of computer users managed to control 51% of the system that underlies the crypto-currency, the group did not abuse its majority. Instead, many members decided to leave and join rival groups.

That is 5,000 times greater than the power of all of the world’s fastest 500 supercomputers combined. Wow. Is this accurate? I don't know much about flops and computer power, but I was under the impression the hashrate was about 135 petaflops. Either way, this is quite a massive achievement!

Hashing doesn't actually involve any floating-point operation. Measuring hashing power in FLOPS just doesn't make sense. That said, the Bitcoin network is very likely to be the biggest distributed computing project ever created... |
