Well I have an average connection for Europe and i could easily support two gigabyte blocks from home, eight megabyte blocks would not be a problem at all.

How long would it take to transmit a 10mb block across the network?  It can't be more than a few seconds.  Besides, this debate about block size should be settled now.  Sooner is better than later.

Well-known cryptographer and digital currency veteran Nick Szabo explained:

So a 1MB block takes vastly more resources than a 1MB web page, for example, because it has to be transmitted, processed and stored with such high redundancy for Bitcoin to achieve its automated integrity.
