Nested Mapping 1. Manage Ownership Information of Housing Society Description : The " NestedMapping " smart contract is a Solidity example that demonstrates the use of nested mappings to manage ownership information of houses within a housing society. The contract allows users to record the ownership details of different apartments within the society, associating each apartment number with the name of its respective owner.
