The block size war saw miners and big blockers get defeated buy what if....
Miners colluded to support a new hard fork that increased block size or introduced tail emissions or changed the hard cap or something.... and then also spooled up 30,000 super cheap Raspberry Pi (or AWS or whatever) Bitcoin Full Nodes and had them support this new fork too?
Now the majority of miners AND nodes would "support" the hard fork so... they'd win?
Basically, while cheap nodes are good for security of the Bitcoin network, it also makes it easier for an attacker to build many of them. They could run 30,000 AWS cloud servers as full nodes for really not much money for months or years on end. Heck, you could even buy thousands of super old Chromebooks or something dirt cheap and do it that way.
Are we missing something? Discuss π
