Tech giant IBM has secured a blockchain-based gaming protocol patent from the United States Patent and Trademark Office (USPTO). The patent, which was published today, was granted to IBM last week; and focuses on the multi-player games that are played online.
Notably, IBM had filed for the patent back in 2018 and has previously hinted at a blockchain use case for gaming, especially through Non-fungible token (NFT) innovations, which can be used assets in a game.
Dubbed the ‘Gaming consensus protocol for blockchain,’ this patent is part of IBM’s vision to create a blockchain ecosystem that supports transactions within MMO games with a big user base. Per the patent’s proposal, the participants in a particular multi-player game can leverage IBM’s blockchain consensus protocol to harmonize the game’s flow. The patent reads,
“In one embodiment, the consensus algorithm is provided as a service from the game network to any blockchain network; thus blockchain networks can delegate consensus to a distributed network of game clients within the gaming peers.”
Other than using the consensus to select subsets for transaction verification within a game, the patent also outlines that participants might receive some incentives based on their fees.
“These fees may be distributed between the participants of the consensus round (i.e., participants/users associated with each gaming peer) as an incentive, be used to maintain the network infrastructure or any other purpose that serves the gaming network and the players.”
While the patent states that participants will only leverage the consensus to order transactions, smart contract execution will remain on the blockchain unless the gaming peers have enough computing power.
“In some embodiments, smart contract execution could be moved to the massively multiplayer online gaming network if the gaming peers have sufficient computing power to perform the additional task of executing the smart contracts and if the business case allows it in terms of security and confidentiality.”
