  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 31155655 or approximately 01/30/2025, 20:15 UTC See (Block height:

How to Vote on the Proposals 161 with Paloma LightNodes

# Mac & Linux
sh ~/Downloads/setup.sh vote-proposal 161 yes

# Windows
docker run --rm --pull=always -ti -v $env:USERPROFILE\\paloma-lightnode:/root/lightnode palomachain/lightnode-client:v2 vote-proposal 161 yes

How to check if 2/3 of the network is online after the vote is complete

curl -s localhost:26657/consensus_state | jq -r ".result.round_state.height_vote_set[0].prevotes_bit_array"

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