But let's be on topic. Blockchains are NOT distributed systems. I haven't seen a post that tells me I'm wrong.
That's because you consider a system to be either distributed or not distributed, with nothing in between. I don't think
any system could be considered distributed by your criteria.
It wasn't "my criteria". It's about what Bitcoin/blockchain networks are. That each node in the network re-validates and re-processes everyone's transactions.
Again, all the non-mining nodes do no processing here, they relay / route at best. Compare as open banking api clients, consuming what banks / payment processors create ( mine ) for them. With those consuming clients you might just be out of sync with the mining network if you store some account data and find out leter in the process, that sth went 'wrong' with the mining processors. But nothing you can do here, except try to mine a correct block on top and claim that your process chain is the correct one.
So only miners keep it up and running
Like banks/ swift/ ach network.
Your home non mining hobby node does nothing in terms of trust
