System and method for implementing a two-sided token for open authentication

A method for implementing a two-side token for open authorization (OAUTH) comprising:

• determining, in response to a first request from a partner application server for access to a first user account information for a user account maintained by a host authorization server, an authorization to share the first user account information by the host authorization server, wherein the first user account information includes multiple levels of access;
• returning, upon determining the authorization to share the first user account information, a response to the partner application server indicating an authorization success;
• writing an access token to a host node of a host-partner shared blockchain, wherein the access token, upon being written to the host node of the host-partner shared blockchain, is synced to a partner node of the host-partner shared blockchain, and wherein the access token, upon being synced to the partner node of the host-partner shared blockchain, is made accessible to the partner application server, the access token being usable by the partner application server to access the first user account information at a first level of the multiple levels of access;
• causing, in response to writing the access token to the host node, a submission, from a host application server associated with the host authorization server to a partner authorization server associated with the partner application server, a second request for a reciprocal access token, wherein the reciprocal access token is usable by the host application server to access a second user account information for the user account maintained by a partner server at a second level of the multiple levels of access.

A non-transitory machine-readable medium having stored thereon machine-readable instructions executable to cause performance of operations comprising:

• determining, in response to a first request from a partner application server for access to a first user account information for a user account maintained by a host authorization server, an authorization to share the first user account information by the host authorization server, wherein the first user account information includes multiple levels of access;
• returning, upon determining the authorization to share the first user account information, an access token to the partner application server, wherein the access token is usable by the partner application server to access the first user account information at a first level of the multiple levels of access;
• and
• causing, in response to returning the access token to the partner application server, a submission, from a host application server associated with the host authorization server to a partner authorization server associated with the partner application server, a second request for a reciprocal access token, wherein the reciprocal access token is usable by the host application server to access a second user account information for the user account maintained by a partner server at a second level of the multiple levels of access.
