Proposal: PIP-97: Paloma Protocol Upgrade to Paloma & Pigeon v2.2.0

Status: Proposed

Author(s): @byte-bandit

Type: Software Upgrade

Discussions-to:

Created: 09/06/2024

Summary

This is a software upgrade proposal for Paloma and Pigeon. We intent to upgrade the protocol of the tumbler network to v2.2.0. This release reintroduces a more streamlined compass handover process, improved gas estimation and bug fixes.

Motivation

The motivations for this Paloma upgrade include the following:

  • Reintroduce compass handover: in the event of an upgraded EVM compass version, Paloma is now able to switch over to the latest contract in one all-or-nothing call, while keeping all further references such as fee manager, contract deployer and ERC20 Tokens fully linked.
  • Improved gas estimation: relayer fees will now be calculated against the consensus over all realistic gas limit estimation values reported by Pigeons. This greatly reduces the cost of the ecosystem, all while making sure relayers are fully rewarded.
  • Further bug fixes include proper attestation of rolled back transactions, stuck SLC calls, failing retries, and more. See the Paloma and Pigeon release notes for more:

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 tool to calculate the approximate Block Height: Huginn - PalomaChain Release Window Planner
  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 23430000 or approximately 09/09/2024, 13:00 UTC See (Block height: Block 23430000 Details - Paloma (GRAIN) Blockchain Explorer)

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
