Granada, the latest Tezos upgrade, is LIVE

06 August 2021
Nomadic Labs

This is a joint announcement from Nomadic Labs, Marigold, Oxhead Alpha, Tarides and DaiLambda.

On 6 August 2021, the Tezos blockchain successfully upgraded by adopting Granada at block #1,589,248. Granada was jointly developed by Nomadic Labs, Marigold, Oxhead Alpha, Tarides and DaiLambda. It follows the Florence protocol upgrade three months ago, and will be the seventh Tezos upgrade since Athens’ activation in May 2019 (overviews here and here).

Granada includes several bug fixes and small improvements and includes the following substantive changes:

  • Emmy*: Granada brings faster finality to Tezos. With the Emmy* update of the consensus algorithm, the time between blocks can now be as low as 30 seconds. Also the number of endorsement slots per block has been increased from 32 to 256. Other constants including rewards and security deposits have been updated.
  • Liquidity Baking: A decentralized exchange between tez and wrapped bitcoins (via tzBTC) will be deployed during the activation including a mechanism to incentivize decentralized provision of liquidity.
  • Gas Improvements: a refactoring of the Michelson interpreter has led to significant performance improvements (typically a decrease of three to six times for already deployed contracts). Note that unfortunately this refactor has introduced a non-critical bug for smart contracts using the COMPARE operator.

Congratulations to everyone involved in the development of this amendment and welcome to the Tezos blockchain, Granada!

We intend to inject our next proposal “H” before the end of September. It has yet more interesting features, large and small. Stay tuned, and happy baking!
