Selfhost your Captcha with Altcha
A couple of days ago I was exploring CAPTCHAs I could use for my website and came across Altcha. Self-hosted PoW captcha with a library published on hex, for some reason nobody bothered to mention it anywhere except on the Altcha website, so I’m doing it now.
PoW-type captchas are meant to give client a computation task making it harder for bots to submit many requests.
