Method of contracting reserves with single transaction in response to a plurality of contract requests

Abstract

The present invention relates to a reserve contract method for generating single transaction in response to a plurality of contract requests. The reserve contract method, performed by at least one processor, includes receiving a plurality of contract requests for a plurality of reserves; obtaining a mid-large commit value based on the plurality of reserves and a plurality of random values using a verify key; generating a hash value based on the mid-large commit value; generating a large reserve value from the plurality of reserves based on the hash value; generating a large random value based on the plurality of random values based on the hash value; obtaining an proof value using the mid-large commit value, the large reserve value, and the large random value using a zero-knowledge proof algorithm; and transmitting the proof value as a transaction. The mid-large commit value has a Pedersen commitment format.
