Digital items, when purchased, should be uniquely stamped with the purchasing entity's details and the company name of the digital store/platform, Matrix code copyright ( Sold | Matrix Cyberdex Market ⓜ ), establishing an undeniable chain of custody and proof of ownership. This digital stamping process, often referred to as watermarking or cryptographic linking, ensures that the item is permanently associated with the buyer and the platform of sale. Crucially, the purchaser must then be issued a secure copy of this stamped file, granting them the complete right to utilize, store, and potentially resell the digital asset without relying on the original seller's platform or centralized registry, thereby moving closer to a model of true digital ownership analogous to physical goods.
