I've recently started learning about blockchain. While I understand how "anyone" can spin up a node on chains like Ethereum, that kind of decentralization feels somewhat meaningless if all (or 99.99%) network calls get relayed through several mainnet endpoints. Because of that, who owns (has the username and password) the mainnet domains, like cloudflare-eth.com and can manage their DNS records? Is this not the largest point of centralization, as well as an (or several) account owner who could take down most Dapps and network activity with a single DNS update?
Cloudflare, in general, is a massive centralization point for the entire internet. Picking a technology here and there and worrying about the amount of centralization, isn't that meaningful.<p>Here is another good one for you to ponder since you're new with blockchain... most bitcoin mining pools sit behind CF too. It doesn't mean that bitcoin is centralized though.<p>The reality of the situation is that while yes... there are a lot of dependencies on CF, that is not the same as centralization. The dependencies could change and give up what CF offers, or they could just route around CF to other similar services. There might be brief outages here and there, but it doesn't negate the core security of these protocols.
