The disclosure provides compositions, systems, and related method for using nanopore-based detection of nucleic acid displacement circuits. In some embodiments, output strands contain orthogonal barcode sequences that are captured by nanopore systems to produce a unique and recognizable current signal. Machine learning models can be used to differentiate a plurality of current signals and, therefore, monitor detection and quantification of multiple nucleic acid displacement circuits in a single pot reaction.
