Introducing Teztnets and Granada, Tezos’ Seventh Protocol Upgrade Proposal

Protocol upgrades are voted on by bakers (validators who help power and govern the Tezos network), giving the community the power to build the future of Tezos.

Granada Upgrade
Granada focuses on a few key factors: reducing gas costs, improving Tezos finality, and the addition of liquidity baking.
Teztnets — A new model for upgrade testing
Alongside the Granada upgrade is the introduction of Teztnets.xyz, a versatile platform to deploy Tezos testnets. Testing upgrades is dependent on coordination between ecosystem participants, validators, developers, and community members; Teznets helps streamline this process across participants.
