Overview

For key value stores where buckets are not supported, we add a byte to the key to represent a bucket. For now, all buckets are hard coded, but we could change that in the future.

Buckets are not really enough to index everything we wish to index. So we have labels as well. Labels are shifted 8 bits left, so they can be combined with the buckets to create a unique key.

This allows us to put the raw directory block at DBlockBucket+L_raw, and meta data about the directory block at DBlockBucket+MetaLabel

MerkleState A Merkle Dag State is the state kept while building a Merkle Tree. Except where a Merkle Tree has a clean power of two number of elements as leaf nodes, there will be multiple Sub Merkle Trees that make up a dynamic Merkle Tree. The Merkle State is the list of the roots of these sub Merkle Trees, and the combination of these roots provides a Directed Acyclic Graph (DAG) to all the leaves. 

                                                     Merkle State
1  2   3  4   5  6   7  8   9 10  11 12  13 --->         13
 1-2    3-4    5-6    7-8   0-10  11-12     --->         --
    1-2-3-4       5-6-7-8    0-10-11-12     --->     0-10-11-12
          1-2-3-4-5-6-7-8                   --->   1-2-3-4-5-6-7-8

Interestingly, the state of building such a Merkle Tree looks just like counting in binary. And the higher order bits set will correspond to where the binary roots must be kept in a Merkle state.
