Storage vs. web access
Odysee uses a distributed storage system, which can not easily be censored. However, it is for practical reasons mostly usable through the web interface odysee.com where the only fast servers holding a complete copy of the distributed data is available. The platform uses this strong position for ads and manipulation of search results.
User contributions and possible attacks
To circumvent censorship, users had to install the native p2p client and contribute bandwidth to the net by active sharing. Further attack vectors: users may be scared away from sharing (i.e. Kazaa, Nebster, etc) or the network may be flooded with useless data (i.e freenet). P2p sharing might be too slow for streaming video.
