Bitlayer Series (68): Bitlayer's Modular Architecture and Scalability
Bitlayer's modular architecture is the key to its standout performance, designed from the beginning to be as flexible as LEGO bricks. At its core, it separates the execution layer, consensus layer, and settlement layer, allowing developers to customize modules based on their needs without compromising overall security. This contrasts with the rigidity of the Bitcoin main chain. Bitlayer anchors its security using the BitVM paradigm while providing high scalability. The team emphasizes that this architecture is not a temporary whim, but a long-term ecological development strategy that enables Bitcoin's second layer to adapt to various application scenarios.
Scalability is reflected in the Turing completeness of the execution layer. It is compatible with EVM, allowing developers to easily port Ethereum contracts to Bitlayer, and add new modules such as privacy protection or derivatives logic. The rollup protocol further amplifies throughput, capable of handling massive transactions without sacrificing speed. For example, game developers can quickly iterate NFT mechanisms with modular design, and community feedback indicates that this is easier to use than other second-layer networks, making scalability much more convenient.
Another highlight is the integration of the recursive BitVM framework. It allows for dynamic upgrades of the architecture, such as adjusting the validator set through epoch reconfiguration to avoid centralization risks. YBTC, as a yield-bearing asset, is also embedded into the modules, supporting expansion into multi-chain environments. Bitlayer's full node design ensures that anyone can independently verify the expansion process, providing high transparency. Some partner projects are already leveraging this aspect to build custom DeFi tools.
Of course, modularity also faces compatibility challenges. However, Bitlayer ensures scalable security through SNARG proofs and HOTS signatures. In the future, as more modules go live, this architecture will enable the Bitcoin ecosystem to expand infinitely, seamlessly integrating from DeFi to Web3.
