| mCaptcha net | A network of mCaptcha instances sharing PoW stats to make mCaptcha more efficient and accessible | We are mCaptcha. We build kickass CAPTCHA systems that give (DDoS) attackers a run for their money. And we do all of this without tracking your users. Oh and did I mention our UX is great? | 2023-10-19 | 2023-10-19 | true | 50 |

mCaptcha requires the webmaster to provide difficulty factor configurations to offer effective protection. Choosing difficulty factors that work for everyone is a hard task because it isn't possible to accurately predict the kind of visitors have. But what if had a system that will improve mCaptcha installations based on performance of it users? Enter mCaptcha net!
The admins of mCaptcha instances can choose to upload truly anonymous Proof-of-Work (PoW) statistics to mCaptcha/survey instances, which other mCaptcha instances can then use to automatically optimize the installations that they hsot.
NOTE: This system is opt-in, webmasters must consent to publishing for the performance statistics from their mCaptcha installation to be uploaded.
Ensuring anonymity
mCaptcha doesn't fingerprint its users. Performance parameters include:
- Time taken to generate PoW
- The difficulty factor for which the PoW was computed
- Type of client library used.
"time":14,
"difficulty_factor":50000,
"worker_type":"wasm"
This doesn't include the usual fingerprinting parameters like User-Agent, cookies, and IP address. Additionally, we use a psuedo ID within mCaptcha to avoid. We also use psuedo IDs within mCaptcha to prevent the underlying mCaptcha installation from being exposing.
