When blocks come in super close together a miner will accept the block **header** of the latest and start mining before actually downloading the entire block and verifying all the data.

However, by only using the header, they can’t put any transactions in the block, because they don’t know which ones to remove without checking the last one. Sometimes they find a valid hash in that small period of time where they don’t yet know what they can actually put into the block… and thus, it stays empty.

I wonder if you could include a bunch of low fee txns & still be relatively certain the block would be accepted & grab a little more in fees 🤔

Maybe a single 1 sat/byte fee txn is actually a miners transaction that got included in the last block because they wanted to mine their own and didn’t care about the fee. If so, then you risk losing 6.25 BTC for a 112 sat fee.

Maybe it works 99.9% of the time. But you’d need to do it *millions* of times for it to make economic sense. Until fees overtake the reward, the empty blocks will continue 😆
