In some implementations, a computing device may obtain an original digital media asset published to a server device along with a distributed ledger that tracks ownership of the original digital media asset. The computing device may generate a customized digital media asset that replaces the original digital media asset, and modify the distributed ledger to indicate the customization or modification of the original digital media asset and identify the customized digital media asset and the ownership thereof. The computing device may publish the customized digital media asset to a server device for distribution. Upon transfer of ownership of the customized digital media asset to a new owner, the distributed ledger may be modified to indicate the new ownership of the customized digital media asset.
