Bitlayer: Technical Architecture and Scalability Design of Bitcoin

I. The scalability problem of Bitcoin Bitcoin is designed with a philosophy of maximum security and decentralization, accompanied by strict limits on block size and transaction throughput. This makes Bitcoin the safest network, but at the same time limits its scalability: Low transaction throughput: Only about 7 transactions/second (TPS). Limited programmability: Only supports simple scripts, lacking complex smart contract features. Current scalability solutions are insufficient: Lightning Network is optimized for micro-payments but does not meet the needs of DeFi or enterprise applications. In this context, Bitlayer emerges as a Layer 2 solution, addressing the above limitations while preserving the core values of Bitcoin: security and decentralization. II. The core architectural principles of Bitlayer Bitlayer is built on four important principles: Security pegged to Bitcoin: All final states of Bitlayer are recorded on the main chain of Bitcoin, ensuring data integrity. Modular architecture: Supports multiple rollup models (ZK-rollup, Optimistic rollup, or a combination ) according to needs. High performance: Bringing high throughput, low latency while maintaining the reliability of Bitcoin. Multi-chain interoperability: Designed to seamlessly connect with Bitcoin assets, wrapped tokens, and even external blockchains. III. The three-layer architecture of Bitlayer Bitlayer operates on three main functional layers:

1. Execution Layer (Execution Layer) Execute transactions and smart contracts off-chain (. Supports Solidity/EVM, enabling dApps from Ethereum to be deployed directly on Bitlayer.
2. Aggregation Layer ) - Rollups ( Combine multiple transactions into one batch, process them in parallel. Use ZK-proof or fraud-proof to verify before sending to Bitcoin. Reduce the computational load on Bitcoin while ensuring verifiability.
3. Payment Layer )Settlement Layer( Put the final state on the main Bitcoin chain. Ensure that even if the off-chain infrastructure is attacked, the real data can still be recovered from Bitcoin. IV. Detailed expansion mechanism Rollup – The heart of BitlayerOptimistic Rollup: Validity assumption, only checked in case of disputes – low cost.ZK-Rollup: Verification through cryptographic proof – high security, near-instant validation.Bitlayer supports both, providing maximum flexibility for each application.Parallel processingOvercomes the single-thread limitations of Bitcoin, significantly increasing transaction throughput.Data Availability solution )DA(Ensures that transaction data is always available for verification, preventing fraud.Inter-rollup communicationAllows rollups to exchange state and liquidity without the need for a centralized bridge. V. Security model of Bitlayer Safety is the top priority: Main chain )On-chain anchoring(: All states are confirmed by Bitcoin.Proof verification): No false state can be recorded.Watchtowers & Validators(: Monitor, detect fraud, and prevent censorship. This helps Bitlayer maintain the trustless principle – not relying on trust in a third party. VI. Tools and supporting ecosystem To promote development, Bitlayer provides: EVM Compatible: A familiar environment for Ethereum developers. SDK & API: Easy wallet integration, dApp deployment, data retrieval. Monitoring & auditing tools: Ensuring transparency and security. Secure cross-chain bridge: Transparently designed and anchored to Bitcoin. VII. Performance and Potential According to initial tests: Throughput: Thousands of TPS ) compared to 7 TPS of Bitcoin(. Confirmation delay: Seconds to several minutes, depending on the type of rollup ) compared to 10 minutes/block of Bitcoin(. Transaction cost: Cheap thanks to batching, opening up DeFi capabilities on Bitcoin at reasonable costs. VIII. Comparison with other solutions Lightning Network: Focuses solely on payments, does not support smart contracts. Stacks: Programmable but uses its own consensus mechanism, with less direct connection to Bitcoin. RSK: Has smart contracts but relies on merged mining, more complex. Bitlayer stands out thanks to: Neo directly into Bitcoin via rollup. Flexible in the verification mechanism. EVM support helps dApps easily migrate. IX. Challenges to be addressed ZK proof computation cost: Requires large resources. Balancing Data Availability and cost: A challenging problem. Decentralization of rollup networks: Avoiding validator centralization. Legal issues: Especially when attracting financial institutions. X. Conclusion: Bitlayer – The technical future of Bitcoin Bitlayer is not just an ordinary Layer 2, but a comprehensive scaling infrastructure for Bitcoin: Thoroughly resolve the TPS bottleneck. Bring programmable finance ) into Bitcoin. Maintain the spirit of security and decentralization. Developer-friendly, ready for organizations, and globally scalable. With Bitlayer, Bitcoin remains a reliable foundational role, while Bitlayer opens a new era – turning Bitcoin into a global financial operating system, from payments, DeFi, to large-scale enterprise applications. Final message: Expanding Bitcoin does not mean compromising its core value – Bitlayer is a testament to that.
