Problem Statement
The current burn mechanism mainly costs active traders, while static holders benefit for free. In the long run, this reduces on-chain activity and harms network security and ecosystem value.
Core Principle
Tax static holding and whales — rob the rich to help the poor — without discouraging normal transactions or liquidity provision.
Specific Mechanisms
(1) Dormancy Tax (Time-Based)
-
If an address has no active operation (transfer, staking, voting, interaction) for N consecutive blocks (e.g., 30 days, TBD), a minimal daily percentage (e.g., 0.01%) of the balance is taxed.
-
Tax is sent to the community pool for subsequent distribution.
-
Any active operation resets the timer.
(2) Progressive Tax (Balance × Time)
-
Threshold examples:
-
100k–1M USTC/LUNC: dormant >60 days → 0.02%/day
-
1M–10M USTC/LUNC: dormant >45 days → 0.05%/day
-
10M USTC/LUNC: dormant >30 days → 0.1%/day
-
-
Larger holders face higher rates or faster escalation to prevent “sleeping whales” from eroding network vitality.
(3) Exemptions
-
Staked (delegated to a validator) counts as active.
-
Providing LP without removing funds.
-
Locked in contracts (e.g., governance escrow, bridge lock).
-
Addresses below a de minimis threshold (e.g., <10k USTC/LUNC).
(4) Whitelist (No Tax)
-
Exchange accounts – Public deposit addresses provided by major CEXs, whitelisted to avoid taxing user funds.
-
Community accounts – Community pool, governance contracts, reward distribution contracts, etc.
-
Validator node operation addresses – Accounts used for block production, signing, delegation operations.
-
Whitelist additions/removals require on-chain governance approval.
(5) Tax Distribution (% of net revenue)
-
Burn
-
Community pool
-
MM2.0 (market-making module)
-
USTC staking reward pool
-
LUNC staking reward pool
-
(Ratios adjustable via governance, recommended quarterly review)
(6) Expected Effects
-
Force large static holders to either participate on-chain or bear costs.
-
Shift burn burden from active traders to long-term idle holders.
-
Reinject tax revenue into stakers and market-making – creating a positive “activity → reward” loop.
-
Maintain or increase on-chain activity, not degrade it.
