Probably here GitHub - ipfs-shipyard/ipfs-dag-builder-vis: See how the DAGs get built
twdragon:
@hector @Jorropo I have updated my repository involving Boxo in a proper(?) way. I will be very appreciated if you have a quick look at it. The code is very simple, and it allows us to recreate CIDv1 with default DAG builder settings. Would be glad to hear about the underwater stones I did not see.
GitHub - twdragon/ipfs-cid-local: An example program in Go to calculate IPFS CIDs
It looks OK to me, it should produce the same CIDs as Kubo, this is easily testable with a few big and small files.
