IronWall Protocol – Client-Side Proof of Work to Stop Bots Without CAPTCHA

Summary: IronWall Protocol replaces CAPTCHA by using a 3KB client-side Proof-of-Work SDK that challenges device computational power to prevent bot attacks. It imposes real CPU costs on bots, making large-scale spamming economically unfeasible while remaining invisible to human users.

What it does

IronWall forces devices to perform computational work before submitting data, verifying legitimacy through CPU effort rather than user interaction. It offers drop-in support for React, Vue, and Vanilla JS with enterprise controls like geo-fencing and IP reputation.

Who it's for

Developers and businesses seeking to prevent automated spam and abuse without disrupting user experience or relying on traditional CAPTCHA methods.

Why it matters

It reduces bot-driven attacks by shifting the cost to attackers’ hardware, avoiding user friction and privacy concerns associated with tracking or cookies.
