THORChain

Introduction to THORChain

THORChain solves one of DeFi’s most persistent problems: swapping native assets across different blockchains without wrapped tokens or centralized intermediaries. Users can swap real BTC for real ETH, not wrapped versions, through THORChain’s decentralized liquidity pools.

Built by an anonymous team and launched in 2021, THORChain uses an innovative economic model where the RUNE token serves as the settlement asset in every pool. This design enables cross-chain functionality while maintaining decentralization - no bridges, no wrapped tokens, no custodians.

The Cross-Chain Problem

Traditional Approaches

Current solutions and their issues:

• Bridges: Security vulnerabilities, centralization
• Wrapped Tokens: Trust required, not native
• Centralized Exchanges: Custody risk, KYC

THORChain’s Innovation

Native asset swaps:

• Real Bitcoin in, real Ethereum out
• Decentralized validators
• Economic security through RUNE
• No wrapped tokens needed

How THORChain Works

Continuous Liquidity Pools

Dual-asset pools:

• Every pool pairs RUNE with another asset
• RUNE serves as settlement layer
• Prices derived from pool ratios
• Automated market making

Cross-Chain Mechanics

Swap flow:

1. User sends BTC to THORChain vault
2. Protocol swaps BTC for RUNE internally
3. RUNE swapped for ETH internally
4. ETH sent from vault to user

Validator Network

Decentralized operation:

• Bonded validators run network
• Threshold signatures for vaults
• Churning for security
• Economic incentives aligned

Technical Specifications

Metric	Value
Consensus	Tendermint PoS
Block Time	~6 seconds
Validator Count	100+
Supported Chains	8+
Vault Type	Threshold signatures
Settlement	RUNE token

The RUNE Token

Unique Tokenomics

RUNE’s critical role:

• Present in every liquidity pool
• Security bonding for validators
• Governance participation
• Value capture mechanism

Deterministic Value

Economic design:

• Total pooled assets bounded by RUNE value
• 3x RUNE value required per pooled asset
• Price must support liquidity
• Built-in demand driver

Utility

RUNE serves multiple purposes:

• Liquidity: Pool pair asset
• Security: Validator bonds
• Governance: Protocol decisions
• Fees: Transaction costs

Supported Chains

Native Integrations

Current support:

• Bitcoin
• Ethereum
• BNB Chain
• Avalanche
• Cosmos
• Dogecoin
• Litecoin
• Bitcoin Cash

Adding New Chains

Process:

• Community proposal
• Technical integration
• Security audit
• Gradual activation

Security Model

Economic Security

Incentive alignment:

• Validators bond more RUNE than pool value
• Misbehavior loses bond
• Attack costs exceed benefits
• Continuous monitoring

Churning

Validator rotation:

• Regular validator changes
• New key generation
• Vault migration
• Security refresh

Historical Exploits

Learning from incidents:

• 2021 exploits occurred
• Rapid response and fixes
• Protocol strengthened
• Security audits ongoing

Conclusion

THORChain provides functionality that no other decentralized protocol offers: true native asset swaps across major blockchains. The innovative economic model using RUNE as a universal settlement asset enables cross-chain liquidity without the trust assumptions of bridges or wrapped tokens.

The protocol has proven resilient, recovering from exploits and continuously improving security. While complexity and RUNE dependency present challenges, the fundamental value proposition remains compelling.

For users seeking to swap native assets without centralized intermediaries and for the DeFi ecosystem seeking genuine cross-chain liquidity, THORChain offers unique infrastructure that traditional bridges cannot match.
