Discussions-to: PIP-12: Upgrade to Paloma and Pigeon v0.11.5

Created: 01/06/2022

Simple Summary

This is a software upgrade for both Paloma and Pigeon binaries and a restart of validator set updates on Ethereum and Binance Smart Chain.


This is a software upgrade for both Paloma and Pigeon binaries that resolves the issues related to valset update failures as well as pigeon jailing while having all configurations correct.


  1. Validator Happiness: Paloma aims to lower the load on validators for debugging relay transaction failures as well as additional information logging
  2. Validator Happiness: Restart EVM deployments to ETH and BNB
  3. Validator Happiness: Less pigeon jailing due to pigeon failures to detect active chaininfos. Less need to restart pigeon!

Specification Overview

This action requires up upgrade of palomad and pigeond relayer software.

Technical Specification

  1. Download and install the latest palomad version: https://github.com/palomachain/paloma/releases/tag/v0.11.5

  2. Download and install the latest pigeon version: https://github.com/palomachain/pigeon/releases/tag/v0.11.5

  3. An upgrade proposal that must be submitted by anyone running a node on the network. This proposal should have the correct block height.

  4. Please use the following spreadsheet to calculate the approximate Block Height. https://docs.google.com/spreadsheets/d/1bglxgcFFhPnOdNYVnBcDyZ_UVuIQqGbtIP8l291jRm0/edit#gid=0

  5. This upgrade proposal requires 10 GRAIN or 10000000ugrain for deposit for voting.

  6. 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.

  7. The Target block height for chain halt for this proposal is tentatively 1202262 or approximately 1/16/2023 12:18:22 PST
