Japanese publishers Square Enix are taking more steps to implement the controversial blockchain technology in their games. Squenix have teamed with blockchain company Oasys, who describe themselves as “environmentally-friendly”. This is because of their less energy-intensive “proof-of-stake” mechanism compared to “proof-of-work” methods such as those used in Bitcoin mining. Oasys's plans fits with Squenix’s intention to develop tokenised economies built on blockchain in their future games.
