Systems, methods, and devices for reducing and/or eliminating data leakage in electronic ledger technologies for trustless order matching

Abstract

The disclosure herein relates to systems, methods, and devices for reducing and/or eliminating data leakage in electronic ledger technologies, such as centralized ledger, distributed ledger technology (DLT) or blockchain-based platforms, for trustless order matching. In particular, in some embodiments, the systems, methods, and devices described herein utilize cryptographic commitments to assign priorities to orders without disclosing the contents of the actual order or plaintext data. In some embodiments, the plaintext data is revealed only after the priorities are assigned to the cryptographic commitments, thereby reducing and/or eliminating potential data leakage that can arise in such electronic ledger platforms or networks. Further, in some embodiments, the subsequently revealed plaintext data can be used to regenerate the cryptographic commitment to verify its correlation. As such, some systems, methods, and devices described herein can provide a trustless order matching system for electronic ledger technologies, such as DLT or blockchain-based platforms.
