Litecoin (LTC) is a cryptocurrency based on blockchain technology, created by former Google engineer Charlie Lee in 2011. It is designed as a 'lighter version' of Bitcoin, aiming for faster and more convenient transactions while maintaining decentralization and security.

Key Features
1. Technical Foundation:
- Based on improvements to Bitcoin's code, using the Scrypt algorithm (different from Bitcoin's SHA-256), lowering mining barriers, and reducing dependence on specialized mining machines (ASICs) (in the early stages).
- Block generation time is about 2.5 minutes (compared to Bitcoin's 10 minutes), with faster transaction confirmation.
- Total supply is 84 million coins (compared to Bitcoin's 21 million coins).
2. Positioning and Use:
- Initially positioned as 'digital silver,' complementing Bitcoin's 'digital gold,' more suitable for small payments and daily transactions.
- As a supplement to Bitcoin, Litecoin is often used to test new technologies (such as SegWit and the Lightning Network) before they are promoted to the Bitcoin network.
3. Decentralization and Security:
- Utilizes a proof-of-work (PoW) consensus mechanism, relying on a global network of miners to maintain ledger security.
- Community-driven, with no centralized institutions controlling it.

Current Status and Challenges
- **Market Position**: Litecoin has long remained among the top cryptocurrencies by market capitalization, but competition has intensified (such as improvements to Bitcoin's payment solutions and the rise of other payment tokens).
- **Price Volatility**: Influenced by overall trends in the cryptocurrency market, regulatory policies, and technological upgrades.
- **Controversies**:
- Founder Charlie Lee sold all of his LTC holdings in 2017, triggering a trust crisis in the community.
- After the upgrade of privacy features, it faces scrutiny from regulatory agencies in some countries.
