I am making a blockchain project using solidity which requires storing various objectIDs corresponding to a personId. The person can add and remove objects and we cannot hard-code the number of objects. I am not being able to use the correct data structure for the same. I have looked for 2d arrays and nested mappings but am unable to figure out.

  • You can use nested mappings.

I think you can make a struct and then create a mapping with it.

  • If you have a concrete example that will make your point more clear.
