That is the number of hashes that were performed on the network since its inception.

Right now, a new block requires 544,200,000,000,000,000,000,000 hashes to be found, and contains ~4000 transactions. So a transaction costs 136,050,000,000,000,000,000 hashes.

With asic miners requiring 11 joules of energy for 1,000,000,000,000 hashes, a small transaction on the network costs, right now, 1496550000 joules. That's roughly the energy needed for a car to travel 600 km.

I just wanted to share these statistics with you.
