Digital asset architecture

A computer system with two or more nodes comprising:

• at least one a private data store that stores private data;
• a global synchronization log that stores public data associated with private data in the private data stores, wherein the private data is stored in a plurality of data stores separate from the global synchronization log;
• a first node operable in a mode as a writer node, wherein the first node is associated with a first private data store that stores first private data, and wherein the first node has access to the global synchronization log to write first public data associated with the first private data and a second mode as a reader node;
• and
• a second node operable in a mode as a writer node, wherein the second node is associated with a second private data store that stores second private data, and wherein the second node has access to the global synchronization log to write second public data associated with the second private data.

A writer node comprising:

• an execution engine;
• an application;
• an internal fault tolerant communication channel;
• and
• one or more replicas of at least part of the system that execute a consensus protocol over the internal fault tolerant communication channel,
• wherein on receiving a request for data from a node, the request may be served by any one of the replicas.

A computer-implemented method performed by a reader node, the method comprising:

• reading public data on a global synchronization log written by a writer node, wherein the public data is associated with private data and the private data is stored in one or more private data stores;
• receiving corresponding private data from one or more private data stores;
• verifying the public data from the global synchronization log with the corresponding private data, and
• based on verifying the public data is verified with the corresponding private data, determining that the corresponding private data is synchronized with the private data.
