PAI Data, Summary of the Project PAI Data Protocol
This addresses data security and access management for users of blockchain systems, but it appears incremental as it builds upon an existing protocol.
The paper tackles the problem of securing and provisioning access to arbitrary data by extending the Project PAI Blockchain Protocol, defining Storage Transactions for data storage and ownership proof and Sharing Transactions for access control, with a comparative analysis against similar blockchain-based file storage systems.
The Project PAI Data Protocol ("PAI Data") is a specification that extends the Project PAI Blockchain Protocol to include a method of securing and provisioning access to arbitrary data. In the context of PAI Coin Development Proposal (PDP) 2, this paper defines two important transaction types that PAI Data supports: Storage Transactions, which facilitate storage of data and proof of ownership, and Sharing Transactions, designed to enable granting and revocation of data access to designated recipients. A comparative analysis of PAI Data against similar blockchain-based file storage systems is also presented.
