Implement Emission rate for Arbitrum

Simple Summary Alter current emission rate to compliment the Arbitrum deployment.

Abstract At this time, Premia's emission rate is currently 0.5 $PREMIA per block on Mainnet, Ethereum Layer 1. On November 30th, Premia will deploy the protocol on Arbitrum, Ethereum Layer 2. Though allocation of total supply to Liquidity Mining incentives has been previously agreed upon, the division of those rewards across EVM-compatible Layer 1s and Layer 2s was not previously outlined. To ensure alignment of vision and incentives between Liquidity Providers, Holders, and the Protocol, a multiple choice selection of options for emissions is being presented.

Specification and Implementation Premia would implement one of the following emission schemes:

• 50/50 Split current mainnet LM emissions between L1 & Arbitrum evenly.

• 25/75 Split of current LM emissions between L1 & Arbitrum.

• 75/25 Move 25% of current mainnet LM emissions to Arbitrum.

• 75/75 Decrease L1 emissions by 25%, match emissions on Arbitrum

• 100/100 Match current mainnet LM emission scheme on Arbitrum 1:1.

If 75/75 or 100/100 were implemented, "accelerated" rewards would last for a maximum of 1-2 month before review and reduction across both chains.

This agreed upon emission rate would go active on November 30th, when Arbitrum launches.

Motivation Continue to provide emissions that reflect and align with Premia's long term vision, prevent unnecessary dilution, and provide sustainable reward systems.
