Computational power of the networked computer system is also leveraged to support the recordation of NFT transactions, including the acquisition of NFT transactions and the transfer of NFTs.

## Claims

### Claim 1

A gaming system, comprising:
a processor; and
computer memory coupled with the processor, the computer memory comprising data stored thereon that, when executed by the processor, causes the processor to:
monitor a plurality of gaming devices in the gaming system to determine a state of the gaming system that is independent of a player's game play;
receive, from a gaming device of a player of a game of chance, a request to redeem a Non-Fungible Token (NFT), the NFT providing a benefit from the gaming system available to an owner of the NFT;
determine that the state of the gaming system is a first predetermined state, the NFT being redeemable when the gaming system is in the first predetermined state but not a second predetermined state, wherein the first and second predetermined states each comprise one of a system event involving a plurality of gaming devices, a system event involving a plurality of players, an occupancy level of the plurality of gaming devices, and occurrence of a random event;
in response to the determination that the state of the gaming system is the first predetermined state, authenticate that the player owns a digital wallet identified by the player;
