Functionality
- Enable cross-chain asset transfers (ETH, BTC, major tokens, stablecoins)
- Support cross-chain messaging for advanced interoperability
- Provide liquidity bridges for fast, low-cost bridging via liquidity pools
- Implement light client verification or trusted validator mechanisms
Reliability
- Economic security models with stake requirements
- Fraud proof mechanisms for dispute resolution
- Recovery mechanisms from bridge compromise without revealing user funds
+ (Privacy, Anonymity, Censorship-Resistance)
- One-way deposit into shielded pool breaks link between source and destination addresses
- Privacy-preserving withdrawals via relayer networks or mixing mechanisms
- Anonymous bridging with no identity disclosure requirement when moving assets
- Prevent front-running protection on bridge deposits
Demand Validation
Potential Users: All L1 users requiring asset onboarding
Use Cases:
- Initial asset onboarding from Ethereum, Bitcoin, and other chains
- Stablecoin transfers (USDC, USDT, DAI) for private commerce
- Cross-chain DeFi operations
- Privacy-preserving asset migration
Possible Implementation
- Shielded pool deposit: Deposits from transparent chains go into a pool, private credentials issued to depositor, withdrawals cannot be linked to deposits
- Relayer networks: Third-party relayers submit bridge transactions, depositor pays relayer privately within shielded ecosystem
- Trusted setup phase: Initial bridge deposits during setup phase mix together, subsequent users benefit from anonymity set
Technical Validation
Risks & Challenges:
- Light client verification vs. trusted validators trade-off
- Maintaining economic security with sufficient stake
- Implementing fraud proofs effectively
- Preventing bridge compromise while protecting user privacy
- Mitigating front-running attacks on deposits
