An Extended Pattern Collection for Blockchain-based Applications

2025-02-22

AI Summary

The lack of systematic architectural design knowledge hinders effective development of blockchain applications. Method: This paper proposes the first pattern engineering methodology for blockchain software architecture, constructing a comprehensive architecture pattern repository spanning five dimensions: off-chain interaction, data management, security, smart contract structure, and user interaction. It introduces an innovative five-dimensional classification framework that distinguishes native blockchain patterns from adapted or refactored traditional patterns, unifying on-chain and off-chain collaboration through the “blockchain-as-a-system-component” integration perspective. The methodology integrates principles from software architecture pattern engineering, smart contract semantics, consensus mechanisms, and design pattern analysis to derive a structured, reusable set of architecture patterns. Contribution/Results: The work fills a critical gap in systematic knowledge for blockchain architecture design, enabling practitioners to make scientifically grounded, context-aware, and compliance-aware architectural decisions in real-world deployments.

Abstract

Blockchain is an emerging technology that enables new forms of decentralized software architectures, where distributed components can reach agreements on shared system states without trusting a central integration point. Blockchain provides a shared infrastructure to execute programs, called smart contracts, and to store data. Since blockchain technologies are at an early stage, there is a lack of a systematically organized knowledge providing a holistic view on designing software systems that use blockchain. We view blockchain as a component of a bigger software system, which requires patterns for using blockchain in the design of the software architecture. In this paper, we collect a list of patterns for blockchain-based applications. The pattern collection is categorized into five categories, including interaction with external world patterns, data management patterns, security patterns, structural patterns of contracts, and user interaction patterns. Some patterns are designed considering the nature of blockchain and how blockchains can be specifically introduced within real-world applications. Others are variants of existing design patterns applied in the context of blockchain-based applications and smart contracts.
