As blockchain technology continues to revolutionize various industries, the efficient and secure storage of data has become a critical challenge. Inspired by blockchain s distributed peer-to-peer networks, security and information storage solutions have found widespread application in high-information environments due to their efficiency, security, traceability, and decentralized nature. However, as blockchain applications expand and the volume of data grows exponentially, the interplay between on-chain and off-chain storage is rapidly becoming a crucial factor in blockchain data management. The motivation for this research stems from the pressing need to address the scalability and performance issues inherent in blockchain systems as they handle increasingly large datasets. Carbon credits data, specifically from a provenance perspective, is multimodal in nature. It can be captured using many different modes and devices and could include images, text, and unstructured data. Current literature lacks a comprehensive analysis of the trade-offs between on-chain and off-chain storage methods, particularly for multimedia data, in terms of their impact on system scalability, operational efficiency, and economic viability. This gap in knowledge hinders stakeholders from making informed decisions about optimal data disposition strategies for their blockchain implementations. This paper aims to bridge this gap by delivering a comprehensive explanation of the data storage methods adopted by blockchain systems, focusing on scalability, efficiency, and economic viability as key evaluation criteria. We analyze the unique connotations and implications of both on-chain and off-chain storage, considering their effects on data retrieval times and overall system performance. Through our analysis, we derive valuable insights to guide the decision-making process in designing and implementing blockchain solutions tailored to specific needs and application scenarios.
