When I was younger, I learned the government was corrupt. But I thought it could be changed by education.

Now I am older and wiser, and I see that the government will never change, but we can create a parallel society among those who are aware.

All of these are public/private keys with repetition, that transcend physical locations (and therefore, create their own law).

Nostr:

No blockchain, you pull it from the relays the poster put it on.

Session:

Blockchain pays the nodes, but no data or metadata stored on there. It strictly incentives the nodes to route and store it.

Bastyon:

Blockchain stores the metadata. But the actual posts are off-chain.

Arweave:

Blockchain literally stores the data up to a certain size, then the rest is off-chain to have infinite scale.

Some will debate over which is better for what. But this misses the point. Fighting among ourselves over different tools, only divides the little community we have. I say, make em all connect.
