Abstract: A secure data fabric (SDF) can include a security platform for sharing data, access and discovery of data, and audit traceability, across disparate data stores and networks. A SDF can leverage blockchain with attribute-based access control (ABAC). A SDF platform can include an immutable data storage medium, a data sharing node, a central processing unit, and memory having software, which can be configured to implement a blockchain and an ABAC module. The immutable data storage medium can be part of a network. The immutable data storage medium can be immutable off-chain data storage for the SDF, and a multi-layered ABAC security policy can be implemented for the SDF. The SDF can have a cross-domain topology model. A multi-party workflow for account keys and digital signatures management can be further implemented. A microservices-based access control module can be configured to dynamically evaluate digital security policies for a secure data fabric.

Abstract: A mining method (10) by which graphitic ore is produced in a form that constitutes an appropriate feedstock for an electrolytic process (20) for the production of graphitic materials through exfoliation. The graphitic ore feedstock may be utilised directly as an electrode in the electrolytic process (20). Also disclosed is a graphitic feedstock for an electrolytic process for the production of graphitic material through exfoliation of that feedstock, wherein the feedstock is less than about 99% graphite (w/w) and of a sufficiently cohesive and conductive nature as to allow electrochemical exfoliation therethroughout without fracturing that might result in collapse of a significant portion of the feedstock or that may result in a loss of conductivity throughout a significant portion of the feedstock.
