Blockchain facilitation of asset transfers between computing systems

A system comprising:

• a processing unit;
• and
• a storage device comprising instructions, which when executed by the processing unit configure the processing unit to perform operations comprising:
• initiating an electronic communication session from a second financial institution to a first financial institution;
• requesting, via the electronic communication session, asset and loan details of a user associated with account identification information;
• receiving, via the electronic communication session, asset and loan details of the user associated with the account identification information;
• generating an electronic transaction record, the electronic transaction record identifying the user, assets, and transfer information related to the assets;
• selecting, at the second financial institution, a cryptographic key from a plurality of cryptographic keys based on an identity of a first entity and a second entity included in the transfer information;
• encrypting the electronic transaction record using the cryptographic key;
• adding the electronic transaction record encrypted using the cryptographic key to a shared ledger data structure;
• in response to the adding:
• transmitting an indication to a delivering system of the first financial institution that the electronic transaction record was added;
• and
• transmitting a notification to computing nodes associated with the shared ledger data structure that the shared ledger data structure was updated;
• and
• transmitting an account transfer request to an automated customer account transfer server, the account transfer request identifying the first financial institution and the second financial institution.

A non-transitory computer-readable medium comprising instructions, which when executed by a processing unit, configure the processing unit to perform operations comprising:

• initiating an electronic communication session from a second financial institution to a first financial institution;
• requesting, via the electronic communication session, asset and loan details of a user associated with account identification information;
• receiving, via the electronic communication session, asset and loan details of the user associated with the account identification information;
• generating an electronic transaction record, the electronic transaction record identifying the user, assets, and transfer information related to the assets;
• selecting, at the second financial institution, a cryptographic key from a plurality of cryptographic keys based on an identity of a first entity and a second entity included in the transfer information;
• encrypting the electronic transaction record using the cryptographic key;
• adding the electronic transaction record encrypted using the cryptographic key to a shared ledger data structure;
• in response to the adding:
