What's the quickest way to find the current blockchain size of the chain you're on? I am sure there are ways to look up an authoritative size for ETH.

EDIT: Apparently I wasn't clear. I am not curious about the size of the file on disk. I want to know the size of the blockchain without downloading it. I want to know the size of blockchains for currencies I am NOT running a client for.

On linux you can use du -sh where -s is the sum and -h is a human readable output.

 ~ $ du -hs ~/.local/share/io.parity.ethereum/chains/ethereum/
10G /home/user/.local/share/io.parity.ethereum/chains/ethereum/
 ~ $ du -hs ~/.local/share/io.parity.ethereum/chains/expanse/
697M    /home/user/.local/share/io.parity.ethereum/chains/expanse/

This works for parity, all chains are in a labelled subdirectory of the chains/ dir.

  • I've edited my post. I'm not asking about the size of the blockchain on disk. I'm asking about the size of the blockchain for blockchains I don't have on disk.

  • There is no way for your client to know that.

  • Fine. I assumed as much. But what other ways are there to know that?

The answer seems to be that this is not possible, based on lots of research.
