You may be facing a situation where your website becomes filled with spam and bot filling contact forms on your site. To be able to solve the issue by the introduction of the CAPTCHAs system. But with different solutions out there, we'll introduce you to what we believe to be the best re-Captcha alternative, h-Captcha.
What is CAPTCHA?
CAPTCHA is an abbreviation of Completely Automated Public Turing Test to tell Computers and Humans Apart.
Its function is to identify humans and spambots. By identification of spambots, it helps out in blocking those fraudulent registrations and relevant activities. The process behind the system that the captcha carries out uses different approaches. The goal is to prevent bots from spamming a website. For example, prevent bots from automatically adding comments on a blog or prevent bots from registering thousands of accounts and blot databases.
Initially, CAPTCHA showed distorted alphabets or numbers to enter in a blank area to open up the website. Lately, a similar process was carried out by asking to check in the box, saying “I am not a robot,” or checking for the relevant 9 picture figure box puzzle correctly.
All these functionalities exist to ensure that robots cannot respond to them and quickly get identified and blocked.

reCAPTCHA or h-CAPTCHA.
Maybe the most commonly used CAPTCHA library is reCAPTCHA from Google. But there are alternatives if you are not keen to send data to Google. Another reason to take a look at the h-Captcha library is the announcement a while ago from Cloudflare. They switched from reCAPTCHA to hCaptcha. Data privacy, performance and quality or major factor that drive us for re-Captcha alternative, h-Captcha.

Another aspect is that h-Captcha provides privacy, benefits the website by rewarding and getting the data labeled. hCaptcha does not make access to the user’s personal information. You can earn money or donate it when the users solve a problem. It provides an incentive in the form of a virtual currency known as Human Tokens (HMT). These tokens can are ed to get image classification services or contribute to the Wikimedia Foundation. The hCaptcha marketplace is powered by the HUMAN Protocol, an open, decentralized protocol for human review that runs on the Ethereum blockchain.

How to set up h-captcha?
Before you can use hCaptcha in your project, an account must be created, which can be done by visiting this Signup page of hCaptcha and entering the required information.
The service is free according to the Plans section on the hCaptcha homepage. However, there is an enterprise plan for customers that need more control.
With your created account, you initially get two keys. A site key and a secret key. The site key will be part of your web application and is therefore public. You can create multiple site keys, one for each of your websites. When you create a site key, you can specify the difficulty level of the CAPTCHA.
On the other hand, the secret key is, as the name suggests, secret, and you should not make this key publicly available.
