All the details can be found here: [How recreate a hash digest of a multihash in IPFS - Stack Overflow](https://stackoverflow.com/questions/51655352/how-do-decode-a-dag-node-object-in-ipfs/51658540#51658540)

I appreciate any help/pointers 🙂

@stebalien thank you! This really helps 🙂

One thing that’s still unclear to me though, shouldn’t the `Data` hash in the outer protobuf also be a multihash? It doesn’t seem to be one, at least not encoded in Base58…

That’s actually just “Hello World!” base64 encoded. Unfortunately, JSON doesn’t _have_ a byte buffer type so we end up encoding byte buffers as base64 strings. You may find this interesting:

Wow - thanks!

I don’t even think I understand. Will read up on that and do further research. This is very helpful!
