The problem with checksums is that hashing takes time and resources, as this network is based on utilising the TOR network such resources come at a premium and are deemed as anti-social by the TOR developers.

I'm not sure if this is something that will be added. The file checksums could be done locally and wouldn't affect the Tor relays. The Tor relays wouldn't be the ones doing the file hashing.

Hash searching is a double edged sword. On one hand it can be used to ensure a specific file is searched for and located on a network, on the other it removes any ambiguity, sometimes ambiguity is helpful.

The weak hashing system used by winmx was a favourable medium in that is was possible to locate the correct file but also to have other files sharing an identical hash, this would ensure deniability in the event that the police came calling, " I was using a file hash to download something else! certainly not that banned ebook officer". This ambiguity could be enough to make a prosecution unviable given other negative factors.

Using good hashing will ensure you get the exact file you requested & offers no challenge to the darkmx network in terms of its string matching capability, as pointed out by the above poster the hashing itself is undertaken locally so in reality something of this sort would be deemed a positive.

Whatever Kevin decides is good with me.
