Modular Blockchain
실행, 데이터 가용성, 합의, 결제와 같은 핵심 기능을 전문화된 레이어로 분리하는 블록체인 아키텍처입니다.
모듈형 블록체인은 블록체인이 수행하는 다양한 기능을 분리함으로써 모놀리식 블록체인 설계에서 벗어나는 것을 나타냅니다. 단일 체인이 모든 측면(실행, 데이터 가용성, 합의, 결제)을 처리하는 대신, 모듈형 블록체인은 이러한 책임을 서로 다른 레이어 또는 전문화된 체인에 분산합니다. 이 모듈형 접근 방식은 각 레이어가 특정 작업에 맞게 최적화될 수 있으므로 확장성, 유연성 및 전문성을 높일 수 있습니다. 예를 들어, 한 레이어는 데이터 가용성에만 집중하고 다른 레이어는 트랜잭션 실행을 처리할 수 있습니다.

It's like a smartphone where you can swap out the camera, battery, or screen for better ones without changing the whole phone. Each part (layer) does its job, and you can upgrade them individually.
🤓 Expert Deep Dive
Modular blockchains represent an architectural evolution aimed at overcoming the scalability trilemma by specializing components. Unlike monolithic designs that tightly couple execution, data availability, consensus, and settlement, modular systems abstract these functions into distinct layers. Execution layers, often rollups, achieve high throughput by processing transactions off-chain and posting state roots or proofs to a base layer. Data Availability (DA) layers are paramount; they guarantee that transaction data is retrievable, enabling light clients and verifiers to reconstruct state without trusting sequencers or validators implicitly. Consensus layers focus on ordering and finality, typically leveraging established PoS mechanisms. Settlement layers provide the final arbiter and security anchor. This separation allows for independent scaling and innovation. For instance, a new execution environment can be developed and deployed on top of existing DA, consensus, and settlement layers, drastically reducing development time and complexity. The key challenge lies in ensuring secure and efficient inter-layer communication and state transitions, often necessitating advanced cryptographic techniques and robust interoperability frameworks to maintain composability and security guarantees across the modular stack.
