Method and system for sovereign data storage

A non-transitory storage medium, storing instructions that when executed by a processor, are configured to implement a data handling method comprising:

• authenticating, via a client identifier, a write request to upload one or more data files to a global database system;
• determining, at an edge node of a plurality of edge nodes forming a proxy layer, relevant data types of the one or more data files;
• determining, at the edge node, a relevant regulatory domain associated with the one or more data files out of a plurality of regulatory domains;
• applying, at the edge node, regulatory domain rules associated with the one or more determined relevant regulatory domains to store the one or more data files on one or more storage devices associated with the one or more relevant regulatory domains;
• assigning, at the edge node, meta data information to the one or more data files, the meta data information being based on regulatory domain rules associated with the one or more determined relevant regulatory domain;
• sending, at the edge node, the one or more data files to a storage engine according to the regulatory domain rules for storage of the one or more data files;
• receiving, at the edge node from the storage engine, a search key associated with the stored one or more data files for local storage at the edge node;
• and
• dispersing, from the edge node to the other edge nodes of the plurality of edge nodes forming the proxy layer, the search keys.
