Blockchain subrogation payments

A computer-implemented method of settling a subrogation claim by a shared ledger, the method comprising, via one or more processors, servers, and/or associated transceivers:

• monitoring a blockchain maintained by a plurality of participants in a blockchain network according to a set of consensus rules for an indication of a subrogation claim, the subrogation claim identifying a subrogation claimant and including evidence regarding an insured loss and a proof-of-identity to cryptographically prove that the evidence regarding the insured loss is originated by a participating entity, the blockchain configured to receive cryptographically signed evidence from participating entities each having a public cryptographic key assigned to the participating entity, and to receive a proof-of-identity for participating entities providing evidence via signed private cryptographic keys, wherein the plurality of participants append data to the blockchain in response to determining that the data satisfies the set of consensus rules, the set of consensus rules including that a participating entity providing evidence includes a proof-of-identity, and that the proof-of-identity corresponds to one of a plurality of predetermined participating entities;
• determining whether the evidence regarding the insured loss satisfies an acceptance condition;
• generating an indication of acceptance of the evidence regarding the insured loss if the evidence regarding the insured loss satisfies the acceptance condition;
• and
• broadcasting to a blockchain network an indication of acceptance of the evidence regarding the insured loss.

A validating network node on a shared ledger network comprising:

• a transceiver configured to exchange shared ledger data with peer network nodes, the shared ledger data including subrogation claim transactions;
• a storage media configured to store a copy of the shared ledger;
• and
• a transaction validator configured to apply a set of consensus rules to shared ledger data received from the peer network nodes, the transaction validator being further configured to append shared ledger data received from peer nodes to the copy of the shared ledger if the shared ledger data satisfies the consensus rules, the shared ledger data including:
• a subrogation claim smart contract identifying a subrogation claimant and a subrogation defendant and including information regarding an insured loss, the subrogation claim smart contract configured to obtain cryptographically signed evidence from participating entities, verify that the cryptographically signed evidence is submitted by the subrogation defendant or the subrogation claimant based on a proof-of-identity, and determine whether a settlement amount has been accepted by the subrogation defendant;
• a cryptographic hash value from the subrogation claimant representing the settlement amount to the subrogation claim smart contract, wherein the cryptographic hash value is included in a transaction with originator information based on a cryptographic public key associated with the subrogation claimant, and wherein the transaction is cryptographically signed using a cryptographic private key of the subrogation claimant;
• and
• an indication of acceptance of the settlement amount from the subrogation defendant.
