I am trying to find the actual size of the etherum blockchain.

I just found older posts that says it is around 21GB.

What are the Ethereum disk space needs?

Blockchain size in ethereum depends in the implementation. In Parity is about 6 GB, in Geth is about 11 GB. Geth is not implementing state pruning, so 11 GB would be a clean sync with --light, while if you don't use this would be 60GB+.

For disk space needs, see this answer.

  • Thank you for your reply, but i already checked this link as you can see above :) Now I am downloading the chain to see how big it is.

    If you got that answer from here: reddit.com/r/ethereum/comments/5om2lw/… then there's actually the hint that it's not --light but --fast

  • @Dan Kinchen Are you sure it's 11 GB with --light option and not with --fast option? Jul 21, 2017 at 13:03
