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 20):
A computer-implemented system for arbitrating a blockchain transaction, the system comprising:\n an encrypted payment contract for a transaction generated between a sender node and a receiver node, the transaction comprising trading a digital content for a cryptocurrency, the encrypted payment contract further comprising a payment condition-checking smart code; an external storage server storing the digital content, or the cryptocurrency, or both; a payment contract node created by a mining node, whereby the executing, by the payment condition-checking smart code is executed by the mining node upon request by the sender node, or the receiver node, or both; a dispute resolution period set by the sender node or the receiver node, the dispute resolution period being for the transaction, wherein the dispute resolution period is set to prevent a malicious attacker from immediately retransmitting cryptocurrency payment after stealing the cryptocurrency payment from the sender's wallet; wherein the dispute resolution period, once set, cannot be modified, such that even 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 another wallet until a transaction is approved and executed; whereby if the execution result of the payment condition-checking smart code is true, payment is executed to the sender 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; an arbitration application submitted by the sender node or the receiver node; a plurality of arbitration nodes selected by the sender node and the receiver node to arbitrate the arbitration application, whereby the arbitration nodes determine the validity of the transaction; wherein the dispute resolution period allows time for the sender node and the plurality of arbitration nodes to verify a veracity of a digital work being offered before making 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 each payment contract follows the dispute resolution period set in the wallet of the sender node; an arbitration report generated b the arbitrator nodes; an arbitration report block requested, by the arbitrator nodes, for the mining nodes to generate; and a subsequent arbitration application submitted by the sender node or the receiver node, upon disagreement with the determination, the subsequent arbitration comprising more arbitration nodes than the prior arbitration application.
