## Abstract

Methods and systems for tracking a game asset used in a video game includes generating a non-fungible token for the game asset used in the video game. Use of the game asset in the video game is monitored during gameplay to identify a qualifying event occurring in the video game in which the game asset is used. The NFT is updated using metadata associated with the qualifying event. The metadata is used to build legacy of the game asset and to track use of the digital asset in the video game.

## Claims

### Claim 1

A method, comprising:
identifying a digital asset usable in a first video game selected by a player for gameplay, the digital asset usable in a qualifying event occurring in the first video game;
generating a non-fungible token (NFT) for the digital asset, the NFT used to keep track of use of the digital asset during gameplay of the first video game;
receiving a request for transferring the digital asset from the first video game to a second video game;
transferring the digital asset from the first video game to the second video game, in response to the request, the transferring causing automatic regeneration of the NFT of the digital asset to associate with the second video game;
monitoring use of the digital asset in the second video game during the gameplay of the second video game to identify a qualifying event occurring in the second video game where the digital asset is used; and
updating the NFT for the digital asset using metadata associated with the qualifying event of the second video game and metadata included in the NFT generated for the digital asset,
wherein the regenerated NFT provides details of legacy of use of the digital asset and is used to track use of the digital asset within the second video game.

### Claim 2 (depends on 1)

The method of claim 1, wherein the request for transferring the digital asset to the second video game is initiated by the player, and wherein transferring the digital asset includes updating the NFT of the digital asset to associate with the second video game.

### Claim 3 (depends on 2)

The method of claim 2, wherein updating the NFT of the digital asset includes updating ownership of the digital asset in the second video game to reflect the player, the player provided with access to the digital asset during gameplay of the second video game.

### Claim 4 (depends on 1)

The method of claim 1, wherein transferring the digital asset includes transferring ownership of the digital asset to a second player in the second video game, an identity of the second player provided in the request for transferring the digital asset, the transferring providing the second player with access to use the digital asset during gameplay of the second video game.

### Claim 5 (depends on 1)

The method of claim 1, wherein transferring the digital asset includes disassociating the digital asset from the first video game to prevent use of the digital asset in the first video game and associating the digital asset with the second video game to enable use of the digital asset in the second video game.

### Claim 6 (depends on 1)

The method of claim 1, wherein the NFT is regenerated with the metadata of the qualifying event every time the qualifying event occurs in the second video game.

### Claim 7 (depends on 1)

The method of claim 1, wherein the metadata for the digital asset for regenerating the NFT is identified using time and space attributes associated with game space of the second video game where the digital asset is used by the player.

### Claim 8 (depends on 1)

The method of claim 1, wherein the qualifying event is an event that meets a predefined threshold defined based on statistics collected during the gameplay of the second video game, and
wherein the predefined threshold is defined by a game developer or a player or a game host or a game content sponsor of the second video game.

### Claim 9 (depends on 1)

The method of claim 1, further includes providing a timeline of the gameplay identifying a plurality of qualifying events that have occurred during the gameplay of the second video game in which the digital asset was used, each of the plurality of qualifying events is provided as a thumbnail on the timeline, the timeline providing a visual indication of the legacy of use of the digital asset identified from the metadata included in the NFT, the thumbnail providing access to a video recording of a portion of the gameplay of the second video game for the qualifying event in which the digital asset was used.

### Claim 10 (depends on 9)

The method of claim 9, wherein the timeline of the gameplay includes details of any qualifying events of the first video game where the digital asset was used prior to the transfer of the digital asset to the second video game, each of the qualifying events of the first video game presented as a thumbnail on the timeline, the timeline providing visibility of the qualifying events in the first video game and the second video game.
