Introduction to BeL2
BeL2, short for Bitcoin-Elastos Layer 2, is a decentralized platform designed to extend Bitcoin's functionality while preserving its core principles of security and integrity. The primary purpose of BeL2 is to enable native Bitcoin (NB) to interact with smart contracts and decentralized applications (DApps) without leaving the Bitcoin mainnet. This is achieved through advanced cryptographic techniques like zero-knowledge proofs (ZKPs) and a novel light client verification system. By focusing on interoperability and programmability, BeL2 empowers Bitcoin to participate in more complex financial applications, such as lending and stablecoin issuance, without compromising its decentralized ethos. For example, through BeL2, Bitcoin can be used as collateral in decentralized loans, allowing users to borrow stablecoins without moving their BTC off the main network.
Main Functions of BeL2
Decentralized Clearing Network
ExampleA user wants to use their BTC as collateral for a loan in USDT. BeL2 allows this transaction to occur without transferring the BTC off the mainnet. The loan is processed through a smart contract on the Layer 2 network, with the BTC remaining secure on the Bitcoin blockchain.
ScenarioIn a real-world scenario, an individual holding BTC can use BeL2's Loan DApp to secure a loan without selling their Bitcoin. The BTC is locked in a smart contract, and the user receives USDT, which they can use for other financial activities. This process is decentralized and does not require trust in any third party, reducing counterparty risk.
Interoperability with Other Blockchains
ExampleThrough the BTC Oracle, BeL2 allows Bitcoin to interact with Ethereum-based smart contracts without the need to wrap or transfer BTC.
ScenarioA decentralized application (DApp) on Ethereum might require verification of a Bitcoin transaction before executing a contract. BeL2 enables this by transmitting the necessary transaction proof via its BTC Oracle, ensuring the integrity of the interaction without moving the BTC off the Bitcoin network.
Native Bitcoin-Powered Smart Contracts
ExampleDevelopers can build DApps that utilize Bitcoin’s security and liquidity directly on BeL2, creating a more versatile financial ecosystem.
ScenarioImagine a decentralized exchange (DEX) built on BeL2 where users can trade BTC for other cryptocurrencies without needing to convert their assets into a wrapped version or transfer them to another chain. The DEX leverages Bitcoin’s robustness and the programmability of smart contracts on the Layer 2 platform.
Ideal Users of BeL2 Services
Bitcoin Maximalists
BeL2 is particularly appealing to Bitcoin maximalists who prioritize the security and decentralization of Bitcoin. These users can benefit from BeL2's ability to extend Bitcoin’s functionality without compromising its core principles. They can engage in DeFi activities like lending and staking while keeping their BTC on the main network, thus avoiding the risks associated with wrapped tokens or centralized platforms.
DeFi Developers and Innovators
Developers looking to build decentralized financial applications that leverage Bitcoin’s liquidity and security are ideal users of BeL2. The platform provides the tools and infrastructure needed to create smart contracts, DApps, and other financial products that can interact with Bitcoin without moving it off-chain. This makes BeL2 an attractive solution for developers aiming to innovate within the Bitcoin ecosystem.

BeL2 Q&A
What is BeL2 and how does it work?
BeL2 is a Layer 2 solution for Bitcoin that enhances its capabilities by enabling smart contracts and cross-chain interactions without compromising Bitcoin’s mainnet security. It achieves this through the use of zero-knowledge proofs (ZKPs) and a decentralized network of arbiters and zkBTC full nodes.
How does BeL2 maintain Bitcoin's security?
BeL2 ensures Bitcoin's security by transmitting only information across chains, not assets. This approach allows Bitcoin to interact with other blockchains and participate in smart contracts while remaining on its main network, avoiding risks associated with cross-chain asset transfers.
What is the BeL2 Loan DApp?
The BeL2 Loan DApp allows Bitcoin holders to use their BTC as collateral to borrow stablecoins like USDT. This system ensures that BTC remains on the main network, offering fixed interest rates, decentralized arbitration, and protection against forced liquidations.
What role do zero-knowledge proofs play in BeL2?
Zero-knowledge proofs (ZKPs) in BeL2 enable smart contracts to securely verify Bitcoin transactions without revealing sensitive information. This ensures privacy and trustlessness in transactions, allowing for the secure execution of smart contracts across different blockchain networks.
How does BeL2 differ from other Bitcoin Layer 2 solutions?
Unlike other Layer 2 solutions focused on scalability or transaction throughput, BeL2 specializes in cross-chain interoperability and smart contract integration. It enables Bitcoin to interact with other blockchains and execute complex financial applications while preserving the integrity of the Bitcoin mainnet.
