Created: 06/06/2024

Simple Summary

This is a software upgrade for Paloma to v1.14.0 tag for Paloma MAINNEST tumbler network. This update also sets the minimum pigeon version to join the network as Pigeon v1.11.3. This release includes refactor upgrades for Gravity support of multiple target chains, pigeon feed features, as well as stability improvements and increased rpc support for Validator happiness.

Abstract

This is a software upgrade for Paloma to v1.14.0 tag for Paloma MAINNEST tumbler network. This update also sets the minimum pigeon version to join the network as Pigeon v1.11.3. This release includes refactor upgrades for Gravity support of multiple target chains as well as upgrade pigeon support for gas limits on target EVM chains, code stability improvements as well as improved validator happiness for RPC support.

Motivation

The motivations for this Paloma upgrade include the following:

  1. Code stability and dependency upgrades
  2. Upgrades for validator happiness for RPC support
  3. Enhancements for cross-chain bridge functionality
  4. Features for Pigeon Feed

Specification Overview

Upgrade Pigeon and set minimum pigeon version for Paloma from governance.

Technical Specification

The upgrade motivations for this new release are as follows:

  1. Upgrade to cosmos v0.50.6
  2. Periodically update evm chain reference blocks to support all rpc providers
  3. Improve cross-chain bridge functionality
  4. Deliver more enhancements for Pigeon Feed.
  5. Code stability improvements
  6. Add minimum pigeon version to governance
  7. More happiness for validators to run Paloma with less overhead

Prior to upgrade

  1. An upgrade proposal that must be submitted by anyone running a node on the network. This proposal should have the correct block height.
  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 18543314 or approximately 06/10/2024, 14:00UTC See (Block height: 18543314)

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"

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

We are upgrading Paloma achieve the following objectives:

  1. Improve validator experience maintaining RPC endpoints on Paloma
  2. Improve cross-chain bridge functionality for n chains
  3. Deliver more enhancements for Pigeon Feed engineering

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 fastest possible execution. Paloma aims to make it easy for developers to control smart contracts on any Solana, Ethereum L1, L2, and L3 chain.
