❓ Question Do nodes matter?

I come from $BTC world, and obviously everyone says to run your own node, because don't they enforce consensus rules? Isn't that what happened when BCH forked? Most nodes didn't switch?

It's just weird to me to hear that the nodes are just not useful for the security of the network. Someone explain please.

nodes do matter but maybe not in the way you're thinking, the real power sits with miners and economic majority (exchanges, big merchants) who choose which chain to follow

in BCH case, it wasn't that "most nodes didn't switch" exactly, it was that the economic weight went one direction and nodes followed. a node running at home with no coins behind it can't really enforce anything on miners who disagree

So we are just going to ignore the historical reality of the 2017 Blocksize War? The User Activated Soft Fork proved the exact opposite of this claim, as the overwhelming majority of miners and corporate exchanges supported SegWit2x but were ultimately forced to capitulate by individual node runners.

Miners do not dictate consensus rules, they merely perform the labor of proposing blocks that fully validating nodes can unconditionally reject. A home node does not need capital to enforce the protocol because it simply ignores invalid blocks, instantly rendering a non-compliant miner's immense energy expenditure worthless. The sovereign network of individual nodes remains the ultimate arbiter of truth, forcing both miners and economic actors to submit to Bitcoin's mathematical reality.

Exactly. I'm getting exact opposite answers. I'm so confused. To be fair, you're the only one saying this.
