Acceptance Criteria

Finality providers are able to timestamp Osmosis blocks on devnet with finality signatures. This will also need concurrent parameter changes on Osmosis which can be done via governance, to enable the taker fee revenue sharing for rewarding these parameter changes at the same time as the software upgrade which enables this functionality.
