Mina Mainnet Beta 2.0.0 Stop Slot Release

Mina Mainnet Beta 2.0.0 Stop Slot Release

This release is the beta phase of the Mina Mainnet upgrade that specifies the stop slot in the codebase that formally begins the upgrade process. This build is intended for use by experienced community members to test with prior to promoting it to a full stable release very soon. While this has been extensively tested; we promote transparency and always welcome feedback.

For this release we have temporarily enabled node status tracking by default to help us track successful upgrade progress. This behaviour can be turned off by starting the node using the --disable-node-status flag.

This release is a beta version of the release that 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 Hour 0, this slot will be initiated. Blocks produced by upgraded stakeholders will be empty, and no transactions will be allowed.

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.

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.
