According to official sources, Layer1 privacy-enhanced blockchain Aleph Zero announced the launch of its mainnet 12.2, with the new version enhancing the contract tray and internal block synchronization request mechanism, aiming to improve performance. Aleph Zero reminds new users that after this version is released, they will not be able to select to create new controller accounts on the mainnet. In addition, the mainnet 12.2 update also introduces proxy accounts, simplifying the pledging process for binding and unbinding. Even if the hidden account is not online, related operations can still be performed, simplifying the overall pledging experience.
