So, turns out Mirror is a nice frontend capable to write onto two blockchains: Ethereum and Arweave. The first one is used as permanent registrar of the event (i.e.: a new post is published), the latter instead is the content storage infrastracture. The media or this text itself will be written on the Arweave blockchain.

I have to admin I did not know Arweave. I will have to study a little bit more how it works and how it is going to maintain the transactions costs as little as they are right now (one single post is less than 0.0001$ to Mirror.xyz).

In the end I have to discover how Mirror is going to find the money to scale all of this new system to a place capable to host thousand of bloggers.

I still have to understand what happens when I decide to edit my post (I saw you can do it). Is the content on Arweave re-writable?

If not, one thing would be amazing: you can kill the frontend but you cannot kill the content. This will be disruptive for censorship resistant environments.

Cheers.
