Claim 0:
1. A system comprising:
a processor; and
a memory communicatively coupled to the first processor, the memory storing instructions which, when executed, cause the processor to perform operations comprising:
generating, via a cryptographic system, an encrypted certificate indicative of a letter of credit issued by a second entity to a first entity, wherein the encrypted certificate comprises a certificate ID;
storing the encrypted certificate in at least one block of a digital distributed ledger system;
distributing the at least one block among nodes of the digital distributed ledger system, wherein the digital distributed ledger system is configured to immutably store the encrypted certificate; and
after distributing the at least one block among the nodes of the digital distributed ledger system, verifying, via a third entity separate from the first entity and the second entity, the encrypted certificate, wherein the verifying comprises:
partially unencrypting the encrypted certificate by applying a private key of the first entity to derive a partially decrypted certificate; and
unencrypting, via the third entity, the partially decrypted certificate by applying a public key of the second entity and the certificate ID to derive a decrypted certificate.
