IBD Block Body Optimization

[michaelsutton]

Goal: Reduce bandwidth during initial block download (IBD) by avoiding redundant header transfers.

Current behavior:

• IBD has two phases: headers download, then block bodies.
• During the block body phase, headers are resent alongside bodies.

Proposed change:

• Introduce a new P2P request/response that returns only hash + body without the header.
• Requires a new P2P protocol version

Outcome:

• Obvious bandwidth optimization by eliminating duplicate header transfers.

It’d be great if we can demonstrate through maybe a graph or chart or something the effect of this on the overall bandwidth consumed.

Even just point A vs point B comparison is fine.

I’d like to also know just how much this impacts total IBD time.

there is no way to " sync the latests", in order to have the node quickly " connected" ( a kind of huge lets say monthly checksum") .
Then to focus like you ask here on optimizing the IBD, while " synced", on the background ? The IBD is a big problem for my raspberry PI nodes, with bad internet connection. @pierre discord.
