Hi -CK

Technical question on CKPool/Bitcoincore if I may.

When a block is found by a miner, how does this data propagate from the miner to bitcoincore and then onto the network

Also, does Bitcoincore propagate the entire block when a block is found or just the block header with the winning hash?

How much data is submitted to the bitcoin network upon finding a block?
Miner sends small amount of data to pool representing what is required to constitute a low hash from its current stratum template.
Pool submits a submitblock message to bitcoin core with the full block data.
Bitcoin core submits a compact block message describing block header, nonce, transaction IDs, prefilled transactions as needed and extra transactions it thinks may be needed.
The amount of data is variable depending on how much the other node knows, and they may request further data. A full block is only sent to nodes that don't avertiseadvertise compactblock support.
