Maybe you could be a bit more specific with this?
Or maybe you could be a bit more specific with your whole post.

The p2p protocol presently only supports propagation of solved blocks in full; i.e., blocks are not compressed.  

However, the Corallo Relay Network does support a sort of compression.  Rather than transmitting all the transactions in a solved blocks, since most the other miners know about them already, it just transmits indices that refer to each transaction (sort of like a map for how the TXs fit in the block). Greg Maxwell claims that the Corallo Relay Network attains a coding gain of about 250 (1 MB is compressed to about 4 kilobytes); however, I believe it is less in practice.  

Techniques like invertible bloom lookup tables (IBLTs) could also be used to compress solved blocks in the future; Rusty Russell is presently researching this possibility.
