Summary:
|
This Recommendation describes a secure and efficient data storage architecture based on DLT systems In conventional DLT systems, transaction data are typically replicated across all nodes, which may raise concerns regarding storage efficiency and data protection. To address this issue, this Recommendation introduces a selective transaction data storage architecture, where transaction data are stored only by nodes associated with the participating entities. It specifies the data storage architecture, the roles of nodes, and operational procedures such as transaction input, deletion, and validation in DLT systems. This Recommendation is aligned with relevant security standards and provides a secure and efficient information storage architecture for DLT systems.
