## Overview

The SkillEndorsement contract is a **decentralized reputation system** built on blockchain technology that enables users to endorse each other's skills in a transparent and immutable way. This smart contract creates a trustless environment where professional endorsements are recorded permanently on the blockchain.

### Key Features

- **User Profiles**: Users can create profiles with their display names to participate in the endorsement system
- **Skill Endorsements**: Users can endorse other users' specific skills with optional comments
- **Anti-Spam Protection**: Prevents self-endorsements and duplicate endorsements for the same skill
- **Transparent History**: All endorsements are recorded with timestamps and endorser information
- **Public Verification**: Anyone can view a user's endorsements and profile information on-chain

### How It Works

1. **Create Profile**: Users must first create a profile with their name
2. **Endorse Skills**: Users can endorse others' skills with comments and context
3. **Build Reputation**: Endorsed users accumulate a verifiable track record of their skills
4. **Query Data**: Anyone can retrieve endorsement history and profile information

### Use Cases

- Professional networking and skill verification
- Decentralized LinkedIn-style endorsements
- Building on-chain professional reputation
- Transparent skill assessment in hiring processes
