correlation between calldata cost vs compute cost
Block propagation time from 0 to 1 blobs is larger than propagation time between 1 to 6 blobs. Even just 1 blob makes a difference.

by design, bloXroute's relays broadcasted blocks thru its BDN, while the blob sidecars propagated thru the p2p
this uncovered a specific CL behavior - it only accepted blobs from the first peer who suggested the block - even if other peers announced they have them
This post-mortem misrepresents the issue as a Lighthouse p2p bug, when in fact it was caused by an untested interaction between Bloxroute's centralised "block distribution network" (BDN) and Lighthouse's HTTP API
it wouldn't have affected the BDN either if it had stuck to the same principle used by other honest block publishers: publish the whole block.One important point that doesn't get enough attention in client development is the information asymmetric btw the validator, builder API, and the relayer stack
