Asset management, registry, and tracking on shared blockchain nodes

A method comprising:

• receiving, by one or more processors of a shared node of a blockchain platform, a request to write data to the blockchain platform,
• wherein the request comprises a user identifier and an entity identifier, the user identifier associated with a user and including an attribute corresponding to an entity associated with the entity identifier, and
• wherein the entity is one of a plurality of entities supported by the shared node,
• executing, by the one or more processors, a hash function against at least the entity identifier;
• validating, by the one or more processors, an identity of the user based on a comparison of the attribute and an output of the hash function;
• selecting, by the one or more processors, first policies or access privileges from a plurality of policies or access privileges corresponding to the plurality of entities supported by the shared node based on the entity identifier, wherein the selected first policies or access privileges are specific to the entity identified by the entity identifier;
• and
• writing, by the one or more processors, the data to the blockchain platform upon successful validation of the identity of the user and based on the selected first policies or access privileges established for the entity.

A non-transitory computer-readable storage medium storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• receiving, at a shared node of a blockchain platform, a request to write data to the blockchain platform,
• wherein the request comprises a user identifier and an entity identifier, the user identifier associated with a user and including an attribute corresponding to an entity associated with the entity identifier, and
• wherein the entity is one of a plurality of entities supported by the shared node,
• executing a hash function against at least the entity identifier;
• validating an identity of the user based on a comparison of the attribute and an output of the hash function;
• selecting first policies or access privileges from a plurality of policies or access privileges corresponding to the plurality of entities supported by the shared node based on the entity identifier, wherein the selected first policies or access privileges are specific to the entity identified by the entity identifier;
• and
• writing the data to the blockchain platform upon successful validation of the identity of the user and based on the selected first policies or access privileges established for the entity.
