CLI flag for "semi-supernode"

[michaelsproul]

Description

A flag to custody half the columns, which allows for reconstruction, was discussed this morning.

We just need a name 🤣

• --semi-supernode?
• --halfnode
• --midnode
• --half-supernode
• --slimnode

Steps to resolve

1. Decide on flag name
2. Implement CLI cruft
3. Implement support in DA checker/CGC management. I guess a --slimnode with lots of validators still needs to custody its full requirements, so the slimnode 50% should just act as a starting point for custody.

This is potentially useful for L2s and their node providers.

--semi-supernode is great !

--subsupernode ?

what about --reconstruct-blobs or a similar more intuitive flag?

Why not provide the freedom to set the min cgc of a node? It defaults to 4, but you can raise it to some number like 64.

So the semi supernode is --min-cgc 64, supernode is --min-cgc 128 or its alias --supernode

Any use case other than blob retrieval (64 & 128)?

I think we could consider these in the future - I think there are many possible blob retrieval approaches (rpc, short lived gossip subscription), and semi-supernode approach is a starting point and a good fit for initial deployment i think (simple and straight froward)
