title_body: How big is the Cardano blockchain (now and in the future)? This may sound a naively simple question, but...
  
  How big is the blockchian today?
  
  How big is it likely to become in future?
  
  
  I note that Daedalus' state directory on my machine is currently ~10.3G.
  Is it correct then to say that that's the &quot;size of the chain&quot; today?
  For the second question, we could hypothesize a number of scenarios, like:
  5 million Digital Identities are issued.
  What impact is that likely to have on storage requirements of Daedalus?
upvoted_answer: I'm only answering about the size for now: on one of the cardano nodes that I just checked some seconds ago
  $ du -sh state-node-mainnet
  9.4G
  
  I can't say how fast it grows. I just look at it from time to time.
