When it comes to blockchain technology, security and scalability are paramount. Projects that efficiently process data while maintaining robust security attract widespread adoption. Among scalability solutions, Layer-1 stands out as the foundational technology for many blockchain projects. If you're curious about the top Layer-1 coins shaping the crypto landscape, you’re in the right place.
What Is Layer 1?
Layer-1 (L1) refers to the base protocol of a blockchain network. It’s the core infrastructure supporting transactions, smart contracts, and decentralized applications (dApps). Key features include:
- Scalability: Enhances transaction speed and reduces costs by optimizing block processing.
- Security: Utilizes consensus mechanisms like Proof of Work (PoW), Proof of Stake (PoS), or Delegated Proof of Stake (DPoS).
- Decentralization: Eliminates single points of failure, ensuring trustless operations.
For example:
- Bitcoin uses PoW for security.
- Solana employs PoS for scalability.
