  2. Please use the following spreadsheet to calculate the approximate Block Height. https://docs.google.com/spreadsheets/d/1eoXoDWWYHIOYbdPiv8B6vfwDUUkelZgeifnX4foa7yw/edit#gid=0
  3. This upgrade proposal requires 10 GRAIN or 10000000ugrain for deposit for voting.
  4. IMPORTANT: The upgrade height is the block height where the chain halts and requires the upgrade. Allow at least one (1) day AFTER voting end time and upgrade-height for 2/3 of the network to have downloaded the new binary and prepped for the switch over to avoid/minimize downtime of the Paloma chain.
  5. The Target block height for chain halt for this proposal is tentative 19705222 or approximately 07/01/2024, 14:00UTC See (Block height: 19705222)

—> needs to return ≥ ~0.67 for the chain to start up again

To see which validators are online with the new binary, use GitHub - blockpane/pvtop: top-like tui for watching validator pre-votes on Tendermint chains
