Introduction: Vietnam's Crypto Boom Demands Layer-1/Layer-2 Clarity
With 68% of Vietnam's 18-35-year-olds actively trading cryptocurrencies (Vietnam Central Bank, 2025 Q2 Report), the country's regulatory landscape now mandates ISO 27001-certified exchanges for domestic operations. As Vietnam ranks 3rd in Southeast Asia for blockchain adoption, understanding Ethereum's Layer-1 vs Layer-2 architectures has become critical for both retail investors and institutional players navigating this $3.2B market.
1. Ethereum Architecture Deep Dive: Layer-1 vs Layer-2 Fundamentals
1.1 Layer-1: Ethereum's Foundation
Ethereum's Layer-1 serves as the settlement layer executing smart contracts and maintaining consensus. Key components:
- Consensus Mechanism: Transitioning from PoW to PoS (Ethereum 2.0)
- Gas Fees: Average $45/transaction pre-optimization (Q2 2025)
- Security: 89.7% attack resistance through proof-of-stake (Vietnam Blockchain Association)
