Abstract

See full text

A blockchain payment involves a transfer of funds from an account of a user to a collateral account of a service provider. The service provider receives a payment intent from the user including a payment index, a random payment ID, and an address of the collateral account. The service provider replaces the address by a commitment and provides the modified payment intent to a majority of statekeepers of a blockchain, receives payment approvals from the statekeepers, each payment approval including the modified payment intent signed with a private key of a respective statekeeper, evaluates the received payment approvals, aggregates successfully evaluated payment approvals, and transmits the aggregation result to the user. The service provider receives a final transaction created by the user after having verified the aggregation result, verifies that the user correctly constructed the final transaction, and accepts the payment in case of successful verification of the final transaction.
