But why are we celebrating centralization of systems that have "decentralization" as their biggest selling point?
I'm not sure we're celebrating it. It's something to be noted. Some applications might find it useful, for running data analysis on the blockchain, but I don't foresee a majority of ETH validators running on this service. Best to avoid Amazon in general given their propensity for censorship.
amazon getting into crypto adds a ton of credibility from an outsider's perspective. even if you're not a fan of amazon, this should have a positive impact on crypto as a whole.
It makes the numbers go up!
How is one more vendor offering to run a blockchain vm centralization? It's just a hosting service.
This is basically half of ankr’s business. They do back and block chain for large companies as well as start ups, and even PCs that want to stake their tokens.
