BOB Launches BitVM Testnet, Paving the Way for Native Bitcoin in DeFi

Introduction to BOB and BitVM

BOB, a hybrid blockchain that merges the robust security of Bitcoin with the innovative decentralized finance (DeFi) capabilities of Ethereum, has officially launched its BitVM bridge testnet. This initiative has garnered support from prominent institutions and DeFi entities, including P2P.org, Lombard, Solv Protocol, Amber Group, Ankr, RockawayX, Fiamma, UTXO Management, Luganodes, and SatLayer. The mainnet for the BitVM bridge and native Bitcoin functionality is anticipated to go live in the fourth quarter of 2025.

Establishing BOB as a Bitcoin DeFi Hub

The introduction of native Bitcoin on BOB distinguishes it from other Bitcoin variants used in DeFi, which often depend on centralized custodians or multi-signature wallets. The BitVM bridge employs a fraud-proof “1-of-N” security model, ensuring Bitcoin’s security without the need for third-party trust. Just as Ethereum maintains its identity on rollups like Optimism and Arbitrum, Bitcoin on BOB will retain its native designation as “BTC.”

Collaborative Efforts in BitVM Development

All partners involved in the testnet are part of the bitvm/acc working group, which is focused on transforming BitVM from a conceptual framework into a functional reality. This collaboration is crucial, as the advancement of BitVM technology alone cannot ensure widespread adoption; it requires the active involvement and operational backing of major institutional and DeFi players.

Expanding Participation Beyond the BitVM Alliance

This testnet launch marks a significant milestone, as it includes partners outside the BitVM Alliance, a collaborative effort among leading BitVM developers. Their participation in running BitVM infrastructure showcases the practicality and viability of these bridges, backed by industry leaders.

Insights from BOB’s Leadership

Alexei Zamyatin, co-founder of BOB and a founding member of bitvm/acc, stated, “Our goal has always been to place Bitcoin at the center of DeFi, and BitVM enables that vision. With native Bitcoin on BOB, simply referred to as BTC and secured by Bitcoin itself, we anticipate a significant surge in Bitcoin DeFi activity. This is why our testnet launch includes a diverse array of partners—institutions, infrastructure providers, liquidity providers, and DeFi protocols—since BitVM offers vast opportunities across the ecosystem.”

Perspectives from DeFi Innovators

Ryan Chow, Co-Founder and CEO of Solv Protocol, remarked, “Joining bitvm/acc and engaging in BOB’s BitVM testnet aligns seamlessly with Solv’s mission to unlock genuine yield on native Bitcoin assets. We view BitVM as a pathway to trustless Bitcoin DeFi, and BOB’s testnet serves as our first tangible evidence of this potential. The trustless architecture of BitVM perfectly complements our objective of delivering institutional-grade yield, entirely based on Bitcoin’s principles.”

Artemiy Parshakov, VP of Institutions at P2P.org, added, “We have always believed that Bitcoin’s true potential lies in its ability to underpin decentralized finance, rather than merely existing as digital gold. BOB’s BitVM bridge signifies a groundbreaking advancement, finally enabling native Bitcoin to engage in DeFi without the trust assumptions that have previously hindered the ecosystem. We are eager to lend our infrastructure expertise to this testnet, as we see BitVM as the key to unlocking trillions in dormant Bitcoin liquidity.”

Advantages of BOB’s Hybrid Model

As a hybrid blockchain, BOB combines the strengths of both Bitcoin and Ethereum networks, serving as a gateway to Bitcoin DeFi. This innovative model introduces several enhancements over existing BitVM bridge designs:

Ethereum-Based Data Availability

BOB utilizes cost-effective Ethereum blobs for fraud-proof data access, eliminating the need for Bitcoin to serve as a data storage medium. Consequently, BitVM on BOB inherits the same level of censorship resistance found in Ethereum rollups like Arbitrum and Base.

Division of Operator Roles

The operator role is divided into two distinct functions: Operator Nodes manage computations, while Operator Liquidity Providers (LPs) supply BTC liquidity for withdrawals. This structure mirrors proof-of-stake systems, allowing for specialization that aligns with institutional offerings, thereby improving efficiency and reducing capital barriers.

Enhanced Collateral Re-use

Based on research from Citrea and CommonPrefix, BOB allows operators to re-use BTC collateral across multiple BitVM instances, significantly enhancing scalability.

Conclusion

The launch of the BitVM testnet by BOB marks a pivotal moment in the evolution of Bitcoin DeFi, setting the stage for a new era of decentralized finance built on the foundational strength of Bitcoin. With the backing of leading institutions and a commitment to innovation, BOB is poised to redefine the landscape of digital finance.
