THORChain（RUNE）代幣經濟學

Overview

THORChain is a cross-chain, permissionless decentralized exchange (DEX) built on the Cosmos SDK, with its native token RUNE at the core of its economic and security model. The token economics of THORChain are designed to balance network security, liquidity, and user incentives through a sophisticated set of mechanisms. Below, we break down the key components: issuance, allocation, usage/incentives, locking, and unlocking.

Issuance Mechanism

• Fixed Supply: RUNE has a capped total supply of 500,000,000 tokens.
• Mint/Burn Dynamics: RUNE is minted and burned in response to lending and borrowing activities. When users borrow against collateral, RUNE is minted and sold for the debt asset; when debt is repaid, RUNE is bought back and burned. This mechanism can make RUNE slightly inflationary or deflationary depending on market conditions and lending activity.
• No Ongoing Inflation: There is no ongoing inflationary issuance; all tokens were created at genesis or through specific protocol events (e.g., lending).

Allocation Mechanism

Initial Allocation (as of June 2022)

• Vesting: Team/advisor allocations (10%) have fully vested as of early 2024. Seed investor tokens (5.2%) were originally locked until mainnet launch or for 12 months, whichever came first.
• Current Distribution: As of February 2024, the largest holders are protocol modules (Bond, Reserve, Standby Reserve, Pool), with the Bond Module holding ~21% of supply, reflecting the importance of network security.

Usage and Incentive Mechanisms

Core Functions of RUNE

• Liquidity Provision: RUNE must be paired 1:1 with external assets in all liquidity pools (e.g., BTC:RUNE, ETH:RUNE). This ensures deep, protocol-native liquidity and aligns RUNE’s value with network TVL.
• Network Security (Bonding): Node operators (THORNodes) must bond RUNE to participate in consensus. The required bond is set to be at least twice the value of non-RUNE assets in the pools, ensuring that the cost of attacking the network exceeds potential rewards.
• Incentive Pendulum: Rewards are dynamically split between node operators and liquidity providers to maintain an optimal ratio (67% bonded, 33% pooled). If the network is under-bonded, more rewards go to node operators; if over-bonded, more go to liquidity providers.

Incentive Pendulum Table

• Transaction Fees: RUNE is used to pay network and slip-based fees, which are distributed to node operators and liquidity providers.
• Governance: RUNE is used for minimal governance, primarily for asset and chain listings/delistings and parameter changes via node-mimir voting.

Locking Mechanism

• Node Bonding: To operate a node, a minimum bond (e.g., ~538,600 RUNE as of early 2024) must be locked. Misconduct results in slashing up to 1.5x the value of compromised assets.
• Liquidity Pools: RUNE and paired assets are locked in pools to provide liquidity. LPs can withdraw at any time, but impermanent loss protection is only fully realized after 100 days.
• Seed/Team Vesting: Early allocations to team and investors were subject to time-based or event-based locks (e.g., mainnet launch).

Unlocking Time

• Node Bonds: Unlocked when a node leaves the active set, minus any slashed amount for misbehavior.
• Liquidity Providers: Can withdraw at any time, but full impermanent loss protection is only available after 100 days.
• Seed/Team Allocations: Early investor and team tokens were locked for up to 12 months or until mainnet launch; all major vesting schedules have completed as of 2024.

Additional Mechanisms

• Impermanent Loss Protection: LPs are guaranteed to break even after 100 days, with protection increasing linearly from day 1.
• Savers Vaults & Synths: Users can deposit single assets (e.g., BTC, ETH) into Savers Vaults for yield, or mint synthetic assets for capital efficiency. These mechanisms further deepen liquidity and drive RUNE demand.
• Mint/Burn for Lending: Lending against LP positions mints new RUNE, which is burned upon repayment, providing a dynamic supply adjustment.

Implications and Nuances

• Security-Driven Economics: The requirement for node bonds to be twice the value of external assets ensures robust security and aligns incentives for honest behavior.
• Liquidity Black Hole: The deterministic value model and deep liquidity pools create a flywheel effect, attracting more assets and users.
• Minimal Governance: THORChain’s governance is intentionally limited, reducing attack surfaces and protocol risk.
• Dynamic Supply: While the supply is capped, lending and synthetic asset mechanisms introduce short-term supply fluctuations, but these are self-correcting via burn mechanisms.

In summary: THORChain’s token economics are engineered for security, deep cross-chain liquidity, and sustainable user incentives, with a fixed supply, dynamic reward allocation, and robust mechanisms for both locking and unlocking value. The system’s design aims to create a self-reinforcing “liquidity black hole,” making RUNE a central asset in the multichain DeFi landscape.
