First when I run `ipfs --offline block stat <ipfs_hash>` and if the hash does not locally exist I get following message: `Error: blockservice: key not found`.

- Afterwards I run following: `ipfs object stat <ipfs_hash>` and after getting a valid output

- I run `ipfs --offline block stat <ipfs_hash>` again , now it always return valid information (hence does not give an error) even the hash is not downloaded. So assuming if `ipfs --offline block stat <ipfs_hash>` gives and `Error` message is not correlated that the given hash is locally downloaded.

How can I resolve this in order to detect if the asked hashed is fully downloaded or not?

I can do something like `ipfs refs local | grep <hash>` , but I don’t want to keep fetch all the hashes and it will be slower when there is hundreds of hashes exist.

Define fully downloaded… if you mean a full DAG with more than one block, you can do something like `ipfs --offline refs -r <ipfs_hash>` and it should return an error if blocks are missing.

When you ran ` ipfs object stat`, it downloaded that single block (but potentially not other blocks that it links to).
