Simple Summary

This is a software upgrade for Paloma to v1.12.1 tags for both Paloma TESTNEST-15 and MAINNEST messenger networks. This update delivers on the following protocol feature requirement: collect pigeon performance metrics to enhance Paloma’s Quality of Service.

Abstract

The Paloma mainnet continues to achieve the goal of fast and reliable validator node support for effective cross-chain communication and cross-chain relay functionality. As part of the effort to optimize the Paloma messaging service, Paloma will collect performance and reliability metrics of each relayer.

Motivation

The upgrade motivations for this new release are as follows:

Specification Overview

This action requires an upgrade of palomad to the latest tag v1.12.1. There is no pigeon upgrade as part of this release All migrations are included and are being tested on the Paloma public testnest paloma-testnest-15. Validators must install the new binary and restart their nodes at chainhalt.

Technical Specification

The latest releases of Paloma and Pigeon are available here and include the change logs for each for review prior to deployment:

  1. Download and install the latest Paloma tag: Release v1.12.1 · palomachain/paloma · GitHub
  2. An upgrade proposal that must be submitted by anyone running a node on the network. This proposal should have the correct block height.
  3. Please use the following spreadsheet to calculate the approximate Block Height. https://docs.google.com/spreadsheets/d/1eoXoDWWYHIOYbdPiv8B6vfwDUUkelZgeifnX4foa7yw/edit#gid=0
  4. This upgrade proposal requires 10 GRAIN or 10000000ugrain for deposit for voting.
  5. 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.
  6. The Target block height for chain halt for this proposal is tentative 12634982 or approximately 02/12/24 15:00 UTC See (Block height: 12634982 )

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

Rationale

The Paloma mainnet continues to achieve the goal of fast and reliable validator node support for effective cross-chain communication and cross-chain relay functionality. This upgrade allows Paloma to upgrade its Compass-EVM client across mutliple chains with one governance vote. The objective is to allow for continuous upgrade of compass, without the need to re-deploy each client with a governance vote for each chain. This is also a security improvement which allows Paloma to upgrade Compass-EVM when critical security upgrades are required.

About Paloma

Paloma wants to be the fastest relay chain in the world with the most decentralized network of validators that can attest to any transaction with fast execution. Paloma aims to make it easy for developers to control smart contracts on any Solana, Ethereum L1, L2, and L3 chain.
