Abstract:
A system and method for arbitrating a blockchain transaction enables a sender node and a receiver node to perform a transaction with a payment contract, and also record the transaction in the blockchain to protect the sender and receiver node from unfair practices; by preventing the receiver node from transferring received payments until a dispute resolution period that is preset by the sender node has expired. The transaction and payment contract are conducted with a payment condition-checking smart code that executes the transaction only when predetermined conditions have been met. The sender node and the receiver node can elect arbitrator nodes through a delegated proof of stake process. The arbitrator nodes verify the transaction, and review submitted arbitration applications. The arbitrator nodes create an arbitrator report that is also recorded in the blockchain. If dissatisfied with the arbitration, a subsequent arbitration, or an offline dispute resolution node can be requested.

Claim (Index 18):
A computer-implemented method for arbitrating a blockchain transaction, the method comprising:\n creating an encrypted payment contract between a sender node and a receiver node, the encrypted payment contract comprising a payment condition-checking smart code, whereby the encrypted payment contract includes at least one of the following: a contract number, a sender node public key, a receiver node public key, a payment condition-checking smart code, a number of arbitrator nodes to be involved in case of dispute, a sender node signature, a receiver node signature, a payment contract hash value, and a contract user data; sending the encrypted payment contract to a mining node; creating, by the mining node, a payment contract block; setting, by the sender node, a dispute resolution period; setting the dispute resolution period to prevent a malicious attacker from immediately retransmitting a cryptocurrency payment after stealing a cryptocurrency payment from a sender's wallet wherein the dispute resolution period, once set, cannot be modified, such that if a wallet key is stolen in a malicious attack, the malicious attack cannot modify the dispute resolution period to a zero day and immediately unlock funds; wherein the sender node presets the dispute resolution period, during which the receiver node cannot transfer the cryptocurrency payment to the sender's wallet until a transaction is approved and executed; transacting a trade between the sender node and the receiver node, the transaction comprising trading a digital content for a cryptocurrency; storing the digital content in an external storage server; executing, by a mining node, the payment condition-checking smart code upon request by the sender node, or the receiver node, or both; if the execution result of the payment condition-checking smart code is true, executing payment to the receiver node, whereby the execution result of the payment condition-checking smart code is true when the digital content is stored in the external storage server and signed by the receiver node before the dispute resolution period terminates; selecting, by the sender node and the receiver node, a plurality of arbitration nodes through a delegated proof of stake process; submitting, by the sender node or the receiver node, an arbitration application; determining, by the arbitration nodes, the validity of the transaction; wherein the dispute resolution period allows time for the sender node and a plurality of arbitration nodes to verify a veracity of the digital work being offered before making a payment; determining the dispute resolution period by at least one of a time, date or set of the number of blocks additionally created after a transaction; wherein the dispute resolution period of a payment contract follows the dispute resolution period set in the wallet of the sender node: generating, by the arbitrator nodes, an arbitration report; requesting, by the arbitrator nodes, the mining node to create an arbitration report block; and submitting, by the sender node or the receiver node, upon disagreement with the determination, a subsequent arbitration application, the subsequent arbitration comprising more arbitration nodes than the prior arbitration application.
