IBM has patented a blockchain-based consensus model for use in transaction processing in multiplayer games.
A patent called Game Consensus Protocol for Blockchain obtained by IBM last week describes a model for selecting a group of users of any game to verify transactions, as well as choosing a leader to generate a block and broadcast it to the blockchain within that group.
“Game nodes that validate a block attach their own signature to the block,” says the patent.
Since the process of protecting and verifying transactions is a service, users who contribute to it can be rewarded. The patent describes a system that can be implemented in multiplayer games such as Fortnite or Call of Duty: Warzone, which involve a wide variety of small transactions.
Although the model described in the patent assumes the participation of users in the consensus to streamline transactions, the developers note that the execution of smart contracts takes place on the blockchain and can only be carried out if the user devices have sufficient computing power.
Recall that at the beginning of the year, IBM received a patent for a system for recording transaction data off the network, and last year the company applied for a patent for a blockchain-based web browser.
