Simple Summary

This is a software upgrade proposal for Paloma and Pigeon both to v2.1.1 Paloma’s TESTNEST and MAINNEST tumbler networks. This release includes a bug fix for resetting the skyway nonce and a new governance proposal message to override the nonce.

Abstract

This is a software upgrade proposal for Paloma to v2.1.1 for Paloma’s TESTNEST and MAINNEST tumbler networks. This release includes a bug fix for resetting the Skyway nonce when a new Compass contract is deployed and a new governance proposal message to override the nonce.

Motivation

The motivations for this Paloma upgrade include the following:

Ensure that the skyway nonce is reset when a new Compass is deployed. This is required for Skyway messages to be relayed.

Specification Overview

The specification for this release includes the following features:

  1. Bug fix to reset the skyway nonce.
  2. Add a governance proposal message, which may be used to override the last nonce across all validators for a given chain to recover from a desync

Technical Specification

Paloma upgrade includes the following:

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 22805165 or approximately 08/29/2024, 6:30 UTC See (Block height: 22805165)

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

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 to achieve the following objectives:

  1. Reset the skyway nonce when a new compass contract is deployed.
  2. Allow for the nonce to be reset via governance.

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