No, I’m not going to sell you on the 42069th cryptocurrency (thank goodness!), I just think that focusing on crypto, and, god forbid, NFTs, completely wastes the potential that blockchains have. Case-in-point: DNS. The centralization of DNS has been a disaster for the internet. The solution: Decentralize DNS with a free register-deregister system. As DNS is now decentralized, hosting fees will decrease dramatically. Laws will also need to be made to prevent DNS-scalping, so as to prevent people from sitting on domains and selling them for high prices. This might be resolved through either domain limiting or traffic tests, where a domain must keep a minimum amount of traffic over time in order to justify it staying registered. Otherwise, it would get deregistered and become freely up for grabs.
I have been playing with IPv6 recently and have my Monero node running over IPv6 so I can connect my wallets to it both when I am at home and away and it works really well actually. I always thought that IPv6 seemed incredibly difficult, but it’s actually a hell of a lot easier than I thought.
