title_body: How will Cardano address the ledger growth problem? Once the ledger size grows beyond the terabyte magnitude, how will Cardano address this issue?
  Storing and querying anything that large seems impractical to me.
upvoted_answer: The answer to this question is not clear yet, as more research is needed into this problem.
  For now, the effort is to prevent the blockchain growing into large sizes with using layer one two solutions such as Hydra and possibly with side-chains, where you won't have just one blockchain but many, so the data might be distributed this way.
  Shredding will be used too to provide a light-weight view of the blockchain, but many services such as Blockfrost will still have to run full archived nodes to access all the data on the blockchain.
