When I joined Biohackathon Europe in Barcelona recently, I knew PacBio HiFi (High Fidelity) sequencing technology  that is highly accurate long read sequencing by circular consensus long-read . For the long read sequencing, there is Nanopore sequencing by Oxfored Nanopore. So, how is the Nanopore sequencing vs PacBio HiFi sequencing? There are papers  about the topic.
The PacBio's blog says that the first complete human genome was done by the PacBio HiFi sequencing on their blog .
The hifiasm  is a software to assemble the PacBio HiFi reads, and it used the Hi-C chromatine interaction (data)  to produce a haplotype-resolved assembly without the sequencing of parents .
