Namada SE 2 Restart 2

Namada SE 2 Restart 1

• TLDR; There was a bug that reordered ABCI messages.

v0.31.2 has a bug that causes jailing operations to be applied in a non-determinstic order. This was caught uniquely due to the bug in v0.31.1, which caused a number of random jailing events.

The current network progressed to block 8671 which resulted in committing a broken state. In order to fix it a majority of validator voting power must upgrade to v0.31.4 and resync.

Steps to upgrade

I would suggest the following steps to upgrade:

1. Stop the validator node
2. Upgrade to v0.31.4
3. Initialize your validator from scratch by running join-network again (same steps as before) but on a new base directory
4. [Important] Move over whatever double-sign protection you use (<chain_id>/cometbft/data/priv_validator_state.json) to the new directory
5. Modify your p2p stack according to this message: https://discord.com/channels/833618405537218590/1192974425423892550/1206615315618857040
   • also according to the peers posted here: https://github.com/anoma/namada-shielded-expedition/tree/main
6. Modify the consensus timeouts in order to speed up the sync
   • vim <base_dir>/shielded-expedition.88f17d1d14/config.toml
     • timeout_propose = "3000ms"
     • timeout_propose_delta = "500ms" (used to be "500ms")
     • timeout_prevote = "1000ms"
     • timeout_prevote_delta = "500ms" (used to be "500ms")
     • timeout_precommit = "1000ms"
     • timeout_precommit_delta = "0ms" (used to be "500ms")
     • timeout_commit = "10000ms"
7. Start the node and sync

Restart tracking

• Please add your status under the column "Restart 2" on the Shielded Expedition Restart Tracker we need at least 2/3 of the voting power

Notes

• Coordinate with the other validators and voting power on Discord and help each other.
• Make sure to change the config.toml in <chain_id>/config.toml and not <chain_id>/cometbft/config.toml - the latter gets overriden
• No need to change the .masp-params.
