PIP-29: Paloma Mainnet and Pigeon Upgrade to v1.1.0

PIP Name: PIP-29: Paloma Mainnet Upgrade to Paloma v1.1.0 and Pigeon v1.1.0

Status: Proposed

Author(s): @LARRY

Type: Software Upgrade

Discussions-to: PIP-29: Paloma Mainnet and Pigeon Upgrade to v1.1.0

Created: 06/02/2023

Simple Summary

This is a software upgrade for both Paloma and Pigeon binaries to v1.1.0 tags after the completion of the public testnet deployment with upgraded binaries. This software upgrade is a security update for EVM developers to limit which Compass-EVM forwarded messages may interact with their contracts.


Paloma v1.1.0 releases new security functionality that allows EVM developers to limit which Compass-EVM forwarded messages may interact with their contracts. Additionally, there are some dependency updates included. Pigeon v1.1.0 also upgrades with improved error logging.


  1. Validator Happiness: Paloma aims to lower the load on validators for debugging relay transaction failures as well as additional information logging for more successful crosschain message relays
  2. Validator Happiness: Additional security to attract more EVM developers to develop on Paloma.
  3. Validator Happiness: Launch GRAIN revenue path for validators and application developers by securing and routing messages on behalf of users of target chain applications.

Specification Overview

This action requires up upgrade of both palomad and pigeond relayer software to the latest tag v1.0.0. All migrations are included and have been tested live on Paloma’s testnet.

Technical Specification

  1. Download and install the latest Paloma tag: Release v1.1.0 · palomachain/paloma · GitHub

  2. Download and install the latest Pigeon tag: Release v1.1.0 · palomachain/pigeon · GitHub

  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

  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 1577895 or approximately 5/22/2023 9am PT

How to check if 2/3 of the network are online after 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

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


The next phase of Paloma will be the launch of decentralized “robots” and “ai” that will be able to execute remotely on any target chain in the digital asset ecosystem. In order to deliver on this promise and create a sustainable GRAIN fee market for validators, we propose to release this version of Paloma to mainnet and begin the roll-out of these intelligent applications. This will also give the community of application developers and application users immediate access to Paloma’s powerful cross-chain message relay systems for a new era of applications and capabilities.

About Paloma

Paloma Protocol is a Cosmos-SDK blockchain protocol custom-built for omnichain communication that allows permissionless controls of any contract on any chain. Built by the teams at Volume, Binary, and Vitwit, Paloma delivers the world’s first intelligently scheduled and automated smart contract transaction execution for the Cosmos ecosystem. The protocol enables developers to remotely control the transmission of value without the need to wrap, bridge tokens, or trust validators with their digital assets.
