Thank you Marcos,

Though written in Rust, bitcrust-db is definitely usable as pluggable
module as its interface will be roughly some queries, add_tx and
add_block with blobs and flags. (Bitcrust internally uses a
deserialize-only model, keeping references to the blobs with the parsed
data).

However, from Core's side I believe network and storage are currently
rather tightly coupled, which will make this far from trivial.

Regardless, I am also hoping (with funding & a team) to build a Bitcrust
networking component as well to bring a strong competitor to the market.

best,
Tomas
