Project mention: So much for CAPTCHA then – bots can complete them quicker than humans | news.ycombinator.com | 2023-08-16What about proof of work based CAPTCHA like https://github.com/mCaptcha/mCaptcha ? Since CAPTCHAs can be solved by bots, at least make it more costly for them.
Project mention: mCaptcha: Open-source proof-of-work captcha for websites | news.ycombinator.com | 2023-08-08Asymmetric PoW algorithms, such as Cuckoo Cycle [1] or the poorly named Equihash [2] (which is not a hash function) do not lend themselves to password hashing, since a given instance can have 0 or 1 or many solutions.

Project mention: Litecoin Surpasses Bitcoin as the Most Used Cryptocurrency on BitPay Payment Platform | /r/CryptoCurrency | 2023-07-06You’re actually waiting longer with litecoin. Just use the lightning network.
Litedoge aka LDOGE, a proof of stake 2.0 cryptocurrency, 2 min confirm time, 500 coins per stake interest. http://litedogeofficial.org the fast fun crypto supported on multiple chat platforms. matrix, reddit, libra IRC, telegram, discord all have access to ldoge blockchain through bill48105 tip bot https://bill48105.github.io/wallet/ and tip.cc tip bot https://tip.cc/currencies/litedoge
Project mention: mCaptcha: Open-source proof-of-work captcha for websites | news.ycombinator.com | 2023-08-08Funnily enough I've recently implemented [0] a little proof-of-work generator (or more specifically a time-lock puzzle [1] generator), which is the base building block on top which something like this can be built.
It's a very cool idea imo, you generate a cryptographic puzzle that's cheap for you to make, cheap for you to verify if its solved, and potentially cheap-enough for legitimate users to solve, but expensive-enough that users making too many requests would find solving them prohibitively expensive.
I wish something like this was bolted onto email protocols, it would just cost more to be a spammer than it'd be worth it.
Interesting how mCaptcha seems based on sha256, I don't know enough but it would be worth checking how much the algorithm can be sped up with (already existing) dedicated ASICs, if the attacker can solve the puzzle like 10000x faster than normal users you just can't crank the difficulty of the puzzle high enough and for motivated attackers this becomes basically useless. Basing this of on repeated squarings, like the RSW paper on time-lock puzzles did, seems potentially better.
