07:02 < kcalvinalvin> dergoegge hey we're on meet.jit.si/utreexo
07:04 < dergoegge> Sorry i will be on in 15min
07:04 < kcalvinalvin> ok no problem
08:07 < kcalvinalvin> on testnet, csn is currently 255MB
08:07 < kcalvinalvin> I'
08:07 < kcalvinalvin> ll see if I can slim that down
08:15 < adiabat> That's not too big.  How big is it without utreexo?

08:21 < kcalvinalvin> I don't know exactly but around ~36G
08:21 < kcalvinalvin> also pruning isn't there with btcd (even though it's trivial to put it in)
08:33 < adiabat> with pruning what would it be?  Like how big is the chaninstate db vs the blocks folder
08:33 < adiabat> though maybe it's hard to distinguish those 2 in btcd

10:17 < kcalvinalvin> adiabat everything besides the actual block files are in the same db so it's hard to tell

13:53 < dergoegge> Testnet headers should be around 152MB (80*1900000)
13:53 < dergoegge> Is there a height to blockhash index?
13:54 < dergoegge> That could be another 60MB(32*1900000)

19:59 < adiabat> the height to blockhash isn't stored anywhere.  I think it's generated on startup and kept in ram
19:59 < adiabat> (just read the headers)
20:00 < adiabat> also... yeah there are a lot of testnet blocks.  We can also cut down header size, as it doesn't need to be 80 bytes
20:00 < adiabat> prevHash can be eliminated, it's totally redundant
20:01 < adiabat> "bits" is also redundant, only needs to be there once every 2016 blocks, etc
20:01 < adiabat> I think you can get headers down by almost half
20:02 < adiabat> I know other bitcoin people have talked about this but nobody's bothered because headers are dwarfed by everything else.
20:02 < adiabat> but in our case, keeping headers around would be the biggest part
