Single Sign-On Solution Using Blockchain

A computer-based system for balancing and control of message transfers, comprising:

• a processor;
• a tangible, non-transitory memory configured to communicate with the processor, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the processor, cause a single sign-on system to perform operations comprising:
• receiving, by the single sign-on system, a registration request comprising a registration credential;
• determining, by the single sign-on system in electronic communication with a blockchain node and using a smart contract, whether the registration credential exists in a blockchain on the blockchain node;
• writing, by the single sign-on system and via the blockchain node, the registration credential to the blockchain in response to determining that the registration credential did not exist in the blockchain;
• and
• propagating, by the single sign-on system in electronic communication with a peer-to-peer network, the registration credential to at least a second blockchain node in the peer-to-peer network for writing to the blockchain.

An article of manufacture including a non-transitory, tangible computer readable storage medium having instructions stored thereon that, in response to execution by a single sign-on system, cause the single sign-on system to perform operations comprising:

• receiving, by the single sign-on system, a registration request comprising a registration credential;
• determining, by the single sign-on system in electronic communication with a blockchain node and using a smart contract, whether the registration credential exists in a blockchain on the blockchain node;
• writing, by the single sign-on system and via the blockchain node, the registration credential to the blockchain in response to determining that the registration credential did not exist in the blockchain;
• and
• propagating, by the single sign-on system in electronic communication with a peer-to-peer network, the registration credential to at least a second blockchain node in the peer-to-peer network for writing to the blockchain.
