Mina Protocol, a lightweight blockchain protocol, has announced that it will undergo the Berkeley upgrade on June 4th, from 09:00 to midnight UTC. During this period, the network will be down, and users who do not run nodes do not need to take any action. However, users who do run nodes should be aware that the network will be unavailable for 15 hours.

The Berkeley upgrade is a significant step forward for Mina Protocol, as it aims to enhance performance and scalability without affecting decentralization. The upgrade is expected to utilize Mina's design to improve performance, making it possible to support fully ZK-supported smart contracts on the mainnet. This will open up a wide range of possibilities for infrastructure and application improvements.

The upgrade process will start at 17:00 Beijing time on June 4th, and any transactions not included in the blockchain before this time will be discarded. After the upgrade, users can resend transactions once the network recovers. The Berkeley upgrade includes several performance improvements, such as reduced slot time and validator optimizations.

The Berkeley upgrade is a testament to Mina Protocol's commitment to innovation and improvement. By enhancing performance and scalability, the protocol is poised to become a leading player in the blockchain space. The emergence of fully ZK-supported smart contracts on the mainnet will open up new possibilities for developers and users alike.

In conclusion, the Berkeley upgrade is a significant development for Mina Protocol, as it aims to enhance performance and scalability without affecting decentralization. The upgrade is expected to utilize Mina's design to improve performance, making it possible to support fully ZK-supported smart contracts on the mainnet. The emergence of fully ZK-supported smart contracts on the mainnet will open up a wide range of possibilities for infrastructure and application improvements.
