Hello everyone,

after the initial blockchain sync at 100% the size is 511GB at actual block number as indicated at umbrel.local, my second node (not an Umbrel) the blockchain data is only 404GB at the same block number.  
Any idea why there is a difference?  
Thanks!  
Greez

Hey mrkaqz, thanks 4 info!

At Umbrel.local I can see the following message: “511,65 GB, including Bitcoin Core, LND and Electrum sever”. Are these three components as big as 107GB? Does that make sense at all?
