To further strengthen ARK’s long-term consensus structure and improve the sustainability of its reward cycle, this proposal introduces two core enhancements:

1. Launch a 720-day ultra-long staking plan to reinforce deep commitment and long-term lockup structure;
2. Establish an Airdrop Reward Backstop Mechanism, allowing dynamic ETH conversion when ARK inflows are insufficient, converting ETH to USDT to repurchase ARK for reward distribution.

This proposal aims to enhance both long-term protocol stability and the continuity of reward distribution, forming a healthier and more resilient growth cycle.

Purpose

Regarding the 720-Day Staking Plan:

1. Strengthen long-term lockup structure and improve protocol stability;
2. Reinforce the principle that “the longer the trust, the greater the rights”;
3. Enhance the compounding effect of time and reinvestment.

Regarding the Airdrop Reward Backstop Mechanism:

1. Ensure stable and uninterrupted airdrop reward distribution, regardless of ARK inflow fluctuations;
2. Optimize the dynamic balance between burn mechanics and reward sustainability.

Implementation Details

• Introduction of 720-Day Staking Plan

1. New staking period: 720 days;
2. Yield calculation logic and DAO energy coefficients will follow the existing model with upgraded multipliers;
3. Smart contract and front-end updates will be deployed upon proposal approval

• Airdrop Reward Backstop Mechanism

When ARK inflows are insufficient to support airdrop distribution, the protocol may:  1. Dynamically convert a portion of ETH into USDT;  2. Use USDT to repurchase ARK from the market;  3. Allocate the repurchased ARK for airdrop reward distribution.

Operational Principles:  - No fixed frequency; triggered only when the reward pool is insufficient;  - All transactions fully transparent and verifiable on-chain;  - No impact on the ATS Treasury structure.

Implementation Schedule

• Contract updates and parameter adjustments will commence within 48 hours after proposal approval;
• The 720-day staking plan and the reward backstop mechanism will go live simultaneously;
• All transactions and execution records will be publicly disclosed and remain permanently verifiable on-chain.
