Tor uses the version in the platform string to detect features, so some alternative implementations claim to be a particular Tor version.
Other alternative implementations might not report a version at all.
At the moment, I see the following platforms reported on the network:
Tor 0.2.4.19 on Windows XP,65833
...
Tor 0.2.9.1-alpha-dev on OpenBSD,1928192
node-Tor 0.1.0 on Linux x86_64,168444
So it appears that node-Tor is still going strong. And everything else just wants to blend in.
A stem script to generate the full list is:
-----
import sys
from stem.descriptor.remote import DescriptorDownloader
def get_bw_to_platform():
bw_to_platform = {}
downloader = DescriptorDownloader()
try:
for desc in downloader.get_server_descriptors().run():
if bw_to_platform.has_key(desc.platform):
bw_to_platform[desc.platform] += desc.observed_bandwidth
else:
bw_to_platform[desc.platform] = desc.observed_bandwidth
except Exception as exc:
print("Unable to retrieve the server descriptors: %s" % exc)
return bw_to_platform
bw_to_platform = get_bw_to_platform()
for platform in sorted(bw_to_platform.keys()):
print("%s,%i" % (platform, bw_to_platform[platform]))
