And what? Everyone can run your own tor node and see in the consensus: if
sinister DA falsified that node key (and sign it!), then that node can proof that fact to everyone too.
And signed consenus data archive from all years tor stats can be downloaded from torproject.
Find one false key from this archive or from your cache of local tor-stats and
proof node authentication forgery to everyone.
In the case of fully decentralised p2p-networks defining trust is more hard.
Without centralised stats analizing and authenticated broadcasting consensus to users,
evil goverment or ISP-like adversary can isolate your connections from "good" nodes and
inject into your network connections
zillions virtually unexist (DPI-emulated) faked controlled bad
nodes with adversary predefined keys, and rerouting your or group of peoples
traffic to surveillance centres.
No need to steel any keys, just decrypt traffic predefined to you with faked nodes on the fly, so good?
If DA is down or compromised then temporally new DA can be started
on new addresses and placed in users tor-configs, then new TBB version will include them.
