Definition ∞ Appchain infrastructure refers to the foundational technology supporting application-specific blockchains. This includes modular components and frameworks enabling the construction and operation of blockchains designed for a single application or specific set of functions. It provides the essential elements for specialized decentralized applications.
Context ∞ The ongoing development of appchain infrastructure addresses the scalability and customization limitations present in general-purpose blockchains. Discussions often center on the trade-offs between shared security models and sovereign chain control, impacting architectural choices for new decentralized applications. These considerations are critical for their long-term viability and performance.
