Shifting 60 gigabytes of data in, say, 60 seconds means an average rate of 1 gigabyte per second, or 8 gigabits per second.
Yeah, that's comforting...
No, but one proposed solution is:
Bandwidth
The network costs of distributing blocks can be minimized by changing the protocol to send blocks as a header plus a list of hashes. Because nodes are very likely to have already seen a transaction when it was first broadcast, this means the size of a block to download would be trivial (80 bytes + 32 bytes per transaction). If a node didn't see a transaction broadcast, it can ask the connected node to provide it.
