It is intended to run alongside with OverSim, so that swarm protocols can be compared existing “traditional” protocols, extend existing algorithms, or run on top of an existing peer-to-peer overlay. text/html 2024-05-27T10:22:43+00:00 Anonymous (anonymous@undisclosed.example.com) https://syscall.org/doku.php/overswarm/ovswvmsemantic?rev=1716805363&do=diff Back OverSwarm VM Semantic Important note!
