Inform me if I am lacking one thing right here:
If a authorities recognised that an adversery of theirs had a variety of bitcoin reserves, could not they simply ‘crash’ the bitcoin community by spinning up sufficient full nodes to realize 51% of the community (not a tough factor to do for a giant authorities)? They clearly could not produce fraudulent transactions or something (speaking about non-mining full nodes clearly). However they may simply cease receiving/validating/appending new blocks. How would any specific node that blindly connects to considered one of these 51%’ers know to not work together with it? How would a given node ‘know’ who to question for chain knowledge? Btw, I perceive the federal government would have NO financial curiosity in doing this. They’d be purely knocking out another person, however that is invaluable sufficient certainly.

The query has the looks of blending up two various kinds of assault
The primary is the place an attacker controls >50% of the worldwide mining hashpower, not 51% of nodes. That is an assault on each node within the community concurrently.
The second is the place an attacker controls all the friends of a node. It is a focused assault on a single node. Since a node would possibly solely have ten friends, this doesn’t essentially contain creating an enormous variety of dishonest nodes. It’s also foiled if the attacked node has contact with just one sincere node. That manner it’ll change into conscious of a series with extra work than the attackers’.
