It looks like you're referring to a paper or project associated with the URL block-blast-76.github.io .
However, I cannot directly browse live websites or verify the contents of that specific GitHub Pages site. Based on the naming pattern, it is likely a project page for a research paper or technical report (possibly related to blockchain, distributed systems, or a game called "Block Blast" — but that seems less likely for an academic paper). block-blast-76.github.io
