Rollback advances, Web3 contrasts emerge

Ubisoft has temporarily shut down the servers for its popular title, Rainbow Six Siege, after hackers injected 2 billion in-game credits into each player’s account. The team announced on X that the game is undergoing live testing with a limited number of players before a complete relaunch. They stated, “Opening the game to a small number of players only, while we complete live tests. More information on the rollback and full live relaunch to come.”

Rainbow Six Siege is a significant title in the Ubisoft franchise, with data from Active Player showing a daily average of over 34,000 active players in December. The possibility of rescinding in-game currency highlights a key difference from genuinely decentralized cryptocurrencies like Bitcoin and Ether. However, as demonstrated by the controversial rollback of the Flow blockchain, this kind of transaction reversal is still a possibility even in some crypto projects.

Ubisoft has been involved in the blockchain gaming space, including a partnership with Immutable earlier this year to integrate its infrastructure into Web3 games like Might & Magic.

In related news, South Korean cryptocurrency exchange Upbit suffered a security breach that resulted in the theft of approximately $37 million in Solana-based tokens. In response, the platform has outlined a comprehensive recovery strategy, committing to reimbursing all affected customers in full using corporate reserves. To enhance future security, Upbit is implementing new deposit addresses and has swiftly resumed services following the immediate technical response.
