Layer 2 Scalability Issues

Architecture

Layer 2 scalability issues fundamentally stem from architectural constraints within blockchain systems, impacting transaction throughput and finality. These challenges often manifest as limitations in base layer consensus mechanisms, necessitating off-chain processing to alleviate congestion. Solutions like rollups and state channels introduce complexities regarding data availability and security assumptions, requiring careful consideration of trust models and potential vulnerabilities. Effective architectural design must balance decentralization, security, and scalability to support complex financial instruments.
