Question about binary merkle root #2

Open ericxtang opened 6 years ago

ericxtang commented 6 years ago

Question for @mrsmkl - why does TB need a binary merkle tree root hash instead of just using the IPFS hash?

Well mostly it is just an implementation detail (binary merkle root is easier to implement). There is one thing to consider: If we know that an IPFS hash is available, we still need to get the chunks, so we would also need to know whether the included chunks are available. Anyway, the mechanism I described will handle all this and convert the IPFS hash into binary merkle root.
