1. A link contract system, comprising:
one or more servers communicatively coupled with two or more communication devices;
wherein the one or more servers are configured to:
verify one or more verifiable credentials (VCs) of one of a first party and a second party;
facilitate communication of a proposed link contract, that includes the one or more VCs, between the parties;
generate a cryptographic hash of the proposed link contract;
add cryptographic signatures to the hash from the parties, thereby establishing a cryptographically signed hash which validates a digitally signed link contract with the verifiable credentials (DSLC-VC), wherein the cryptographic signatures are facilitated using private cryptographic keys and are one of generated and verified by computer system agents; and
provide the cryptographically signed hash to the parties as proof of agreement to the DSLC-VC;
wherein the DSLC-VC is machine readable and human readable.
