Ripple is a private currency of a corporation. Transactions go through the ripple company. Accounts can be frozen, its not mineable. Ripple is not a real cryptocurrency.
"Ripple is not a real cryptocurrency" => No True Scotsman fallacy? Who decides what is a real crypto? Using an immutable ledger, cryptographically validation and etc doesn't help?
It's not just the inability to mine that keeps the XRP token from being a cryptocurrency, but also that more than half is held by a central authority. It's a
blatant ponzi, rivaled only by Facebook's Libra in the transparent grift. Also confusing that cryptocurrency advocates tolerate it at all, as a redundant bank project/attack
No big banks will ever actually adopt Ripple, they already control international transfers and set the rates/fees themselves. They'll only pump it when it looks like crypto can succeed
...but still, each node is expected to make a judgement of other nodes, right? 1,they == trustworthy, 2,they != sybils. Contrast this with PoW or PoS where no trust is required...
PoW/S is proof of investment in system. I don't need to know who they are. Conversely, I could spin up a ripple server but I doubt anyone would connect to it till they knew who I was.
my point is PoW/S is trust in objective impersonal metrics. Ripple requires you make a 'descision' of which other nodes you trust, prob based on WHO you think they are.(right?)
I think you didn't get it right, Ripple gateways are not equivalent of Bitcoin mining nodes. They are equivalent of bitcoin addresses. Obviously you have to make a decision to
Transfer funds to a business entity. Running a gateway is not necessary for all users but it's required for bigger businesses running on Ripple, like Bitstamp.
Anyway comparing it to PoW is not that much useful. Obviously PoW is more secure but it's also more expensive and is created to address a different usecase
