PIP-59: Paloma Mainnet Upgrade to Paloma v1.13.4

PIP Name: PIP-59: Paloma Mainnet Upgrade to Paloma v1.13.4

Status: Proposed

Author(s): @Birdlady

Type: Software Upgrade


Created: 04/25/2024

Simple Summary

This is a software upgrade for Paloma to v1.13.4 tag for Paloma MAINNEST tumbler network. This update sets the minimum pigeon version to join the network as Pigeon v1.11.1 which includes fixes to Geth transaction types that were blocking fast relays on the target evms.


Paloma upgrade to v1.13.3 included an upgrade to Ethereum’s geth library. Th paloma protocol is trying to send a tx with the option. Either gasPrice or maxFeePerGas & maxPriorityFeePerGas should be set. For Ethereum mainnet, we need to maxFeePerGas & maxPriorityFeePerGas because Ethereum transactions are tx-type is 2. All pigeons in order to relay will need to upgrade their pigeons.


The upgrade motivations for this new release are as follows:

Specification Overview

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

Technical Specification

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

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 16236376 or approximately 04/29/2024, 11:00UTC See (Block height: 16236376)

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 Cosmos SDK 0.50.5 upgrade uncovered performance issues with IAVL, CometBFT, and the UpgradeHandler. These issues require a chain halt due to breaking changes in consensus.
