  • Sample code
              
tree = MerkleTree()
# raw bytes or str bytes
tree.add_node('00')
tree.add_node('01')
tree.add_node('02')

# extra node is added during make to provide a perfect binary tree
tree.make()

tree.get_root()
'8633f3f58bd5719152d1f244ad09616dbad359515721e8a59ad0eb1823ae3531'
tree.get_proof(2) # node index
