Bitcoin has traditionally been limited in its yield-generating potential due to its Proof-of-Work (PoW) consensus mechanism. Unlike Proof-of-Stake (PoS) chains, Bitcoin lacks native staking functionality. However, the rise of BTCFi (Bitcoin Finance) is creating innovative ways for Bitcoin holders to earn yield without compromising security. The BTCFi ecosystem comprises two primary components: the BTC layer with restaking protocols, and asset standards like ARC20 and BRC20. This article explores how emerging players in the BTCFi space are reshaping Bitcoin restaking and compares their key advantages.
Current Bitcoin Restaking Models
Bitcoin restaking isn't new this cycle, with established projects like BounceBit, Coredao, and Stakelayer, alongside recent attention-grabbers Babylon and Symbiotic.
Babylon's Approach
Babylon's Bitcoin staking solution introduces several innovations:
- Remote Staking: Utilizes Bitcoin's UTXO model and scripting system for staking, slashing, and reward distribution. Users face no slashing risks—only node operators are affected.
- Timestamp Server: Records PoS chain events on Bitcoin's mainnet for tamper-proof timestamps.
- Three-Layer Architecture: Bitcoin (base layer) → Babylon (middleware) → PoS chains (top layer). Uses Cosmos for scalability, enabling native Bitcoin staking to secure Babylon's PoS network.
Other Notable Protocols
- Symbiotic: Backed by Lido and Paradigm, it currently supports only WBTC staking via third-party custodial addresses.
- CoreDAO: Offers both native staking (without fund transfers) and custodial staking (locking BTC to mint coreBTC). Only custodial staking is live.

Bitcoin Restaking Ecosystem
Several protocols enhance liquidity and utility for staked Bitcoin assets:
| Protocol | Key Feature | TVL/Adoption |
|---|---|---|
| Bedrock | Pre-staking leader for Babylon (30% share) | Supports uniBTC minting |
| Lombard | Manages restaking, issues LBTC on Ethereum | Cross-chain DeFi integration |
| Lorenzo | Dual-token system (stBTC + YAT) | Accumulates Babylon rewards |
| Pell | First security network atop Babylon AVS | $200M+ TVL, 410K+ addresses |
Emerging Trends
- PumpBTC: Simplifies WBTC/BTCB staking via third-party custodians.
- Solv Protocol: Cross-chain liquidity layer for WBTC/BTCB.
- Stakestone: Forthcoming STONEBTC for multi-chain yield.
Advantages and Challenges
Pros:
- Babylon/CoreDAO leverage Bitcoin's timestamps to streamline PoS staking.
- Symbiotic benefits from Lido/Paradigm's ecosystem support.
- Babylon pioneers trustless native staking.
Cons:
- CoreDAO/Symbiotic still rely on third-party custody.
- Babylon's PoW+PoS hybrid has passive security reliance on Bitcoin.

FAQ
Q: Is Bitcoin restaking safe?
A: Protocols like Babylon minimize risk by avoiding fund transfers, but custodial solutions involve third-party trust.
Q: What’s the difference between BTCFi and Ethereum restaking?
A: BTCFi doesn’t directly inherit Bitcoin’s security; it builds complementary yield mechanisms.
Q: Which protocol offers the highest yields?
A: Lorenzo’s dual-token system and Pell’s multi-strategy approach currently lead in flexibility.
Conclusion
Transforming Bitcoin into a yield-bearing asset significantly boosts its liquidity. Unlike Ethereum’s mature ecosystem, BTCFi protocols like Babylon and Symbiotic are building infrastructure from scratch. Projects such as Solv and Lombard are pioneering multi-reward systems and cross-chain integration. As BTCFi evolves rapidly, its innovations promise to redefine Bitcoin’s utility beyond "digital gold."
