Issues can occur when multiple users attempt to update the same data in different ways. For example, even if two individuals update the location to the same spot, the resulting CID ends up being identical due to the shared information. To prevent this, it may be necessary to search for and locate a particular file. Conflict-free resolution can be achieved through usage of CRDTs (conflict-free replicated datatypes). Polytrees—a type of search tree—also offer an efficient indexing feature that is suitable for Merkle data structures.
