Bitlayer, Layer 2 solution based on the paradigm BitVM, aims to transform Bitcoin into a platform capable of competing with next-generation blockchains, while retaining its legendary security.
What is Bitlayer?
Bitlayer is a Bitcoin second-layer (Layer 2) solution that pushes the technological boundaries of the world's most secure blockchain. Unlike Bitcoin in its native form, which is limited in terms of transaction throughput and programmability, Bitlayer offers an infrastructure capable of executing smart contracts complete while directly inheriting the security of Bitcoin.
The solution is based on an innovative rollup architecture combined with the BitVM paradigm, allowing for the first time continuous verification of Layer 2 state transitions directly on the Bitcoin blockchain.
This approach goes far beyond simply recording data: it truly anchors security in Bitcoin's proof-of-work mechanism.
The founders and the team behind the project
Bitlayer Labs was founded in October 2023 in Singapore by Charlie Hu and Kevin He, two well-known entrepreneurs in the blockchain ecosystem. Co-founder Charlie Hu emphasizes the project's ambition: to make Bitlayer the computing layer for Bitcoin and unlock the massive potential of the dormant capital on the network.
The team currently has around 70 employees and has successfully raised a total of $25 million in several funding rounds. The Series A funding round, co-led by Franklin Templeton Digital Assets ABCDE valued the company at $300 million. making Bitlayer one of the most promising Bitcoin Layer 2 projects in the industry.
Investors include major players such as Framework Ventures, Polychain Capital, GSR Ventures, Flow Traders and FalconX, as well as angel investors.
Technical specifications: a disruptive innovation
Two-level architecture
Bitlayer operates on a two-tier architecture combining a Proof-of-Stake consensus mechanism for rapid block production with a rollup framework that anchors its security to the Bitcoin network. This design allows validators to process transactions quickly while providing a high-throughput EVM-compatible environment.
Security equivalent to Bitcoin
Bitlayer's major innovation lies in its recursive verification protocol based on BitVM. This mechanism allows for the verifiable settlement of a continuous chain of Layer 2 state transitions on Bitcoin, guaranteeing security rooted in the Bitcoin consensus mechanism itself.
Dual purpose for greater flexibility
Bitlayer offers two levels of purpose:
- Gentle ending : obtained in less than a second via the PoS consensus, offering a responsive user experience with security guaranteed by the validators.
- finality : reached when the L2 state is definitively settled on the Bitcoin blockchain, requiring approximately seven days due to the optimistic rollup challenge period.
EVM compatibility and Turing completeness
The platform is fully compatible with the Ethereum Virtual Machine, allowing developers to deploy complex smart contracts and decentralized applications on Bitcoin. This Turing completeness opens the door to use cases in DeFi, gaming, and much more.
BitVM Bridge: The Bridge Without Trust
In July 2025, Bitlayer launched its BitVM Bridge Mainnet, a trust-minimizing bridge solution for transferring Bitcoin assets. Unlike traditional bridges that rely on centralized entities, the BitVM Bridge uses an advanced smart contract framework to drastically reduce trust assumptions.
How and why to use Bitlayer?
Who is concerned?
Bitlayer is aimed at several categories of users:
- Bitcoin holders wishing to generate returns on their dormant assets
- Developers seeking to create decentralized applications with Bitcoin security
- DeFi protocols wanting to exploit the massive liquidity of the Bitcoin ecosystem
- End users requiring fast and inexpensive transactions
Main use cases
👉 DeFi and BTCFi Bitlayer allows you to create currency markets, lending protocols, and decentralized exchange platforms directly on Bitcoin.
👉 Micropayments Thanks to reduced fees and fast completion, Bitlayer makes it possible to use Bitcoin for small, everyday transactions.
👉 complex applications From decentralized finance to online gaming, Bitlayer's Turing completeness opens up a universe of applications previously impossible on Bitcoin.
A growing ecosystem
Since launching its V1 mainnet in April 2024, Bitlayer has experienced explosive growth. The platform now hosts nearly 300 projects and ranks first among Bitcoin scalability solutions with a total value locked (TVL) exceeding $500 million, according to DeFiLlama.
The ecosystem includes leading protocols such as Desyn for yield farming, Jasper Vault for options trading with leverage up to 200x, and numerous infrastructure projects including data availability and bridging solutions.
Advantages of Bitlayer
- Security inherited from Bitcoin By anchoring its operations in the Bitcoin consensus, Bitlayer benefits from the most robust security in the blockchain industry.
- Optimal performance : With completion in less than a second and high throughput, the user experience rivals the most efficient blockchains.
- Drastic cost reduction Transaction fees are significantly reduced compared to Bitcoin's Layer 1, making new use cases viable.
- Mature ecosystem With nearly 300 projects and strong institutional support, Bitlayer offers a rich and diverse environment.
- Continuous innovation The ambitious roadmap includes the launch of V2 (with OpVM) and already a preview of V3, demonstrating a strong commitment to technological evolution.
Limitations and points of attention
- Technical complexity Bitlayer's sophisticated architecture can present a learning curve for new developers. Furthermore, from the user's perspective, it requires technical knowledge of DeFi.
- Youth of the project Launched in 2024, Bitlayer still has to prove itself in the long term in the face of varied market conditions and unforeseen technical challenges.
- Dependence on the PoS consensus Although hard finality is guaranteed by Bitcoin, soft finality relies on the economic integrity of validators.
- Relative centralization : Like any optimistic rollup, security depends on the existence of at least one honest participant willing to challenge frauds.
Final word: DeFi enthusiasts are satisfied.
By resolving the old Turing dilemma between security and completeness, Bitlayer paves the way for a new generation of decentralized applications anchored in the world's most trusted blockchain.
Time will tell if this ambition will be fully realized, but one thing is certain: Bitlayer is writing a new chapter in Bitcoin's history, one where digital gold becomes a complete and powerful financial infrastructure. For Bitcoin holders and those seeking multiple uses, developers, and DeFi enthusiasts, Bitlayer offers an opportunity to participate in this revolution from its very beginning.
