A new DoS protection mechanism for Tor leveraging Proof-of-Work.

    Man the comments section on the tor project blog are just as smooth brained as YouTube comments sections.

    I kinda expected better of the average reader than commenting "hmm another captcha" 6 hours after they explicitly clarified this isn't visible to the user (which was also implicit in the whole 30ms time specified).

    Like 10 points for reading the article but -30 for reading comprehension.

    This isn't the first proof of work "captcha" system, there's several already out there.

    The article is quite vague on how this is implemented. Does it require JS to be activated to work? That would be a big NO for anyone really looking into privacy, but could work for those who use TOR basically as a free VPN to escape stupid geoblocking rules.

    And what will prevent DDOSers from just creating dummy requests without the intention to ever wanting to solve any PoWs? It will still allocate resources on the other side.

    Definitely a step in the right direction for the Tor network. If they wanted to take it to the next level, they could use blockchain to enable people to buy "priority" access in some way (Monero, lightning, their own token, whatever). This could subsidize people who host Tor routers, while making sure a free tier was enabled for all users who need it. This could massively increase the size of the Tor network as right now Tor server hosting is just done out of expensive altruism. Bigger network = bigger free tier = faster Tor for everybody.
