PoW-Shield-Go

Proof of work shield written in Golang to protect DDoS atacks

Description

PoW Shield is a DDoS protection solution for the OSI application layer, functioning as a proxy that employs proof of work to secure the communication between the backend service and the end user. This project offers an alternative to traditional anti-DDoS methods, such as Google's ReCaptcha, which are often cumbersome for users. With PoW Shield, accessing a protected web service is seamless: just navigate to the URL, and your browser will handle the verification process automatically.

Key Features

• Proof of Work Mechanism: Uses computational challenges to verify legitimate users and deter attackers.
• User-Friendly: Eliminates the need for users to solve complex captchas.
• Seamless Integration: Easily integrates with your existing backend services.
• Web Service Structure
• Proxy Functionality
• PoW Implementation
• WAF Implementation
• Multi-Instance Syncing (Redis)
• SSL Support
