yeah but in theory, can't they just spin up a bunch of nodes anyway (given their unlimited money)
They can't stop any one of us from running our nodes.
yeah but if the nodes are easy to run, what is stopping them from running a bunch of nodes and 50% attacking the blockchain?
Check out the cost of running a 51% attack(50% ain't good enough), not to mention the "killing the golden goose"issue: as they spend the money, bitcoin's price would plummet. Makes no economic sense.
ah I see, you would need the ASIC miners to perform the attack, not just nodes. I am not sure why that went over my head.
You need 51% of the hash rate
I see. When it comes to BCH, is it more vulnerable to this kind of attack because of the increased block size? Does it require better hardware with the larger block size?
I don't pay attention to BCH, but this may provide insight: https://decrypt.co/49819/bitcoin-cash-rebels-launch-51-attack-to-destroy-bch-hard-fork
Segwit was seen as a compromise, separating transaction data from signature data. Large blocks would have hurt decentralization. By now few of us plebs could afford to run our own nodes. BlackRock and Fidelity would run all the nodes eventually.
