...A BUNCH OF DELETED AD HOMENEM ATTACKS ...
Are you now ready to join us here in the real world, where O(n^2) attacks are a problem, or are you going to stick with the wishful thinking, hand-waving, and "Because Mining Incentives!" slogan?
OFFTOPIC, BUDDY.
Why don't you go create some 1MB spam transactions on testnet so the adults can continue discussing how we're going to save Bitcoin from being a useless relic of the past?
Malicious transactions are possible on the Bitcoin network. This has been known for years. It's not a valid argument for keeping the blocksize back in the Stone Age.
Returning to the topic at hand, has anyone looked at this chart lately?
