The Snapshot governance page shows that the Arbitrum community has initiated a vote on the "Long-term Incentive Pilot Program" proposal, planning to distribute 25-45 million ARB tokens to protocols built on Arbitrum. The proposal states that it aims to establish a long-term incentive pilot program for DAOs to test new incentive designs and answer questions necessary to ensure that Arbitrum is ready for long-term commitments. This plan will distribute ARB tokens to protocols within 12 weeks.
