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.
No, just no. If you really believe so it shows how very little you understand how Bitcoin works.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.
