DBHash --> DBTree
DBTree --> R1Hash
DBTree --> R2Hash
DBTree --> RNHash

R1Hash --> R1Tree
R2Hash --> R2Tree

R1Tree --> T11
R1Tree --> T12
R2Tree --> T21
R2Tree --> T22

note bottom of DBHash
  Single hash represents
  entire database state

  Benefits:
  - Version control
  - Efficient diffing
  - Distributed sync
  - Integrity verification
