Methods and systems described herein prevent traders from using order intent and hardware solutions to advance their order position by obfuscating the order until execution and by using a digital ledger to assign priority of the orders. As described herein, using a series of cryptographic key pairs, one side of a transaction can be created, matched, and executed while a public record is recorded and maintained but obfuscated (i.e., not publicly transparent) until after the transaction is completed.
