Avalanche announced the upcoming AvalancheGo upgrade "Banff", which will be activated on the Fuji testnet at 22:00 on October 3, and the mainnet activation time will be announced later. Banff unlocks the ability for subnet creators to use their own tokens to activate proof-of-stake validation and uptime-based rewards on their subnets, meaning anyone can simply stake their tokens to Put it on the P-Chain to become the validator of the subnet. Subnets that opt-in to these new features must be converted to elastic new-style subnets at one time. When Elastic Validation is enabled, the creator permanently locks the subnet against future modification (relinquishing control keys), specifies the Avalanche Native Token (ANT) that validators must use for staking and will be distributed as staking rewards, and provides a set of control subnets Parameters of how the staking mechanism works (eg what is the minimum staking amount).
