Captcha Canvas Challenge

Captcha Canvas Challenge is a standalone image captcha package for Bitsocial communities. It renders randomized text onto a canvas and lets a community ask authors to solve the image before a publication is accepted.

• npm package: @bitsocial/captcha-canvas-challenge

Installation

npm install @bitsocial/captcha-canvas-challenge

Where It Fits

Captcha challenges are useful when a community wants a simple interactive gate for low-stakes spam resistance. This package is intentionally narrow: it provides the challenge implementation, while the community or Bitsocial node decides when and how to present it.

For stronger protection, combine it with broader moderation or risk-scoring systems instead of treating a captcha as a complete anti-spam strategy.

Current Package Reference

This page is intentionally an overview, not a mirrored setup guide. The package README is the source of truth for current challenge names, registration examples, CLI examples, supported options, requirements, and security notes:

Prefer the upstream README when configuring a live community, because package options and install flows are versioned with that package rather than this website.
