According to PANews, Mina Protocol, a lightweight blockchain protocol, announced that it would undergo the Berkeley upgrade on June 4th, from 09:00 to midnight UTC. During this period, the network will be down. Users who do not run nodes do not need to take any action during the 15-hour upgrade process.
Starting from 17:00 Beijing time on June 4th, until the upgrade process is completed, no transactions will be included in the blockchain. Any transactions not included in the chain before 17:00 Beijing time on June 4th will be discarded. After the upgrade, when the network recovers, users can resend transactions.
The Berkeley upgrade is expected to enhance performance, utilizing Mina's design without affecting scalability or decentralization. With the emergence of fully ZK-supported smart contracts on the mainnet, an unlimited number of infrastructure and application improvements become possible. The Berkeley upgrade also includes reduced slot time and validator optimizations among other performance improvements.
