Abstract
A computer-implemented method for transferring a total data record from an input node to an output node using a blockchain. The total data record may be a total payment, in some cases, such as using Bitcoin. The output node shares public key material and the input node selects unspent transaction outputs to use in paying the total value, and determines a plurality of outputs payable to the output node in fixed denominations. The input node generates an output address for each output using the public key material and a respective random number, and mixes the inputs and outputs in one or more coin mixing transactions. A nonce public key for each output, generated based on the respective random number, is shared with the output node either separately or through the blockchain, and the output node can derive the corresponding private key for each output address, enabling it to search for and identify the outputs to which it can then claim ownership.
