Modular Blockchain
実行、データ可用性、コンセンサス、決済などのコア機能を専門的なレイヤーに分離するブロックチェーンアーキテクチャ。
モジュラーブロックチェーンは、ブロックチェーンが実行するさまざまな機能を分離することにより、モノリシックブロックチェーン設計からの転換を表しています。単一のチェーンですべての側面（実行、データ可用性、コンセンサス、決済）を処理する代わりに、モジュラーブロックチェーンは、これらの責任をさまざまなレイヤーまたは専門チェーンに分散します。このモジュール式アプローチにより、各レイヤーを特定のタスクに合わせて最適化できるため、スケーラビリティ、柔軟性、専門性が向上します。たとえば、あるレイヤーはデータ可用性のみに焦点を当て、別のレイヤーはトランザクションの実行を処理する場合があります。

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.
