Mainnet Stable Stop Slot Release 2.0.0
This release is the first phase of the Mina Mainnet upgrade that specifies the stop slots in the codebase that formally begins the upgrade process.
Node operators MUST upgrade to this version as soon as possible, starting immediately and before 27 May, 2024 to ensure we have a maximum percentage of stake running on this new version to successfully continue with the planned upgrade.
It is crucial for block producers to continue running their nodes with version 2.0.0 until the stop network slot is reached so that the network reaches consensus on which block to upgrade from. The team at o1Labs will also be collecting network data from these nodes for the post-upgrade release build.
This release will set the stage for the upcoming mainnet upgrade by defining the stop slots in the codebase. This stop slot will take effect in just 2 weeks on upgrade day: June 4th, 2024, and thereby kicking off the upgrade process.
Stop Transaction Slot: At Tue Jun 4 9:00 UTC, this slot will be initiated. Blocks produced by upgraded stakeholders will be empty, and no transactions will be accepted.
Stop Network Slot: 5 hours after the stop-transaction-slot, nodes in the Mina network will stop creating new blocks, marking a pause in block production. This is intentional and necessary for the upgrade to occur smoothly.
For more information regading these milestones please see our high level plan here
After these two important stop slots, we’ll publish the post-upgrade Berkeley package. We’ll be working very closely with the community and the archive node operators during this time to migrate data from the network and validate the ledger state.
Supported environments include macOS, Linux (Debian 10, 11 and Ubuntu 20.04 LTS), and any host machine with Docker.
