@NickSzabo4 Unless specially protected with integrity protocols (e.g. https://) of course; then underneath can only delay & deny service.
@NickSzabo4 But even delays and denials of service can mess with the integrity of some protocols (e.g. blockchains).

@NickSzabo4 unless they are a super powerful like the permissionless block chain of Bitcoin. -
@MyTsonictsunami No. Bitcoin is also vulnerable to this. -
@NickSzabo4 damn, I stand corrected.Any remedy? -
@MyTsonictsunami Need more variety and redundancy in random gossip "broadcast" protocol, which may mean _smaller_ block sizes. -
@MyTsonictsunami OTOH reducing variety and redundancy by increasing the blocksize makes Bitcoin more vulnerable to this kind of attack. -
@NickSzabo4 are side chains a possible answer? -
@MyTsonictsunami Sidechains don't address this problem. -
@NickSzabo4 smaller block size seems to be at odds with where core devs want to go. - 2 more replies
