IBM has patented a blockchain-based consensus model designed for use in transaction processing in multiplayer games.
The patent, titled “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 selecting a leader to generate a block and broadcast it to the blockchain within that group.
“Game nodes that verify a block attach their own signature to the block,” the patent states.
Since the process of protecting and verifying transactions is a service, users who contribute to it can receive rewards. The patent describes a system that can be implemented in multiplayer games, such as Fortnite or Call of Duty: Warzone, which involve a wide range of small transactions.
Although the model described in the patent assumes the participation of users in the consensus for the ordering of transactions, the developers note that the execution of smart contracts takes place in 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 data about transactions outside the network, and last year the company applied for a patent for a web browser based on the blockchain.
