Abstract
The disclosure provides improved methods and systems for processing, storing, sharing, retrieving, writing and accessing data (content) on a blockchain e.g. Bitcoin. The invention may form part of a protocol for storing, searching and accessing the data. In particular, improved efficiency and also enhanced access control permissions are provided. An embodiment of the disclosure comprises the step of processing at least one blockchain transaction (Tx) comprising: a protocol flag; a discretionary public key (DPK); and a discretionary transaction ID (DTxID). These are discretionary in the sense that they are not required as part of the underlying blockchain protocol but in accordance with the present invention. This combination of features enables portions of data to be identified, retrieved and shared on a blockchain, and also to be linked/associated with one another when provided in a plurality of transactions. It enables a graph or tree-like structure to be constructed, which reflects the hierarchical relationships between portions of data, facilitating their processing, searching and sharing.
