Embodiments of a method and/or system (e.g., for improved single molecule sequencing, etc.) can include preparing a set of unique molecular identifier (UMI)-based molecules associated with a set of target nucleic acid sequences; facilitating generation of (e.g., generating, etc.) a set of tagged nucleic acid molecules based on the set of UMI-based molecules and a set of nucleic acid molecules corresponding to (e.g., including, etc.) the set of target nucleic acid sequences; and/or facilitating (e.g., performing, etc.) single molecule sequencing with the set of tagged nucleic acid molecules.
