Any guides on how to host at home? I'm always afraid that opening ports in my home router means taking the heavy risk of being hacked. Does using something like CloudFlare help? I am a complete beginner.

Edit: Thanks for all the great response! They are very helpful.

This may be a very stupid idea, and I know blockchain has a bad reputation for scams, but I was wondering how viable the Internet Computer blockchain might be for a Fediverse universal ID. From what I read on their website, data is much cheaper to host on their blockchain (something like 70 million times less than on Ethereum). It is also possible to host entire websites with Wasm on it). So here are my questions:

• Is there an ongoing effort to make a universal ID for the Fediverse or are we not there yet?
• Does blockchain have its place in the Fediverse, not necessarily for crypto, but for decentralized data storage.
• Do you think something like the Internet Computer blockchain could serve as a universal ID for the Fediverse?

Again, sorry if this is a dumb post, I am really new to the concept of this space as a whole.

Hey, I'm pretty new to the concept of the Fediverse and would like to explore it more. I do think I know how it works, but I was wondering this: is there an all-in-one app for it? Say, one that allows you to browse Lemmy and Mastodon at the same time, and possibly even more platforms?
