Layer 1 Blockchains: Scalability, Security, and Layer 2 Tradeoffs

Summary

This document introduces Layer 1 blockchains as base networks that validate transactions and support decentralized applications. It outlines scalability pressure as network activity grows, linking congestion, higher fees, and slower processing to the need for every node to validate transactions. Proposed responses include changing consensus mechanisms and using Layer 2 systems such as rollups or sidechains to shift some activity away from the base chain.

It also describes the relationship between Layer 1 and Layer 2 networks, notes applications in decentralized finance, NFTs, and supply chains, and identifies security, decentralization, energy use, and operating costs as relevant considerations. The explanation is introductory rather than comparative: many section headings are followed by missing content, and it gives no measurements, network case studies, or method for assessing tradeoffs. Despite the title’s mention of CAMP and FDV, it does not define either term or explain how fully diluted valuation relates to Layer 1 networks.

Key ideas

• Layer 1 networks execute and confirm transactions at the base level of a blockchain system.
• As network use increases, throughput limits can contribute to slower transactions and higher fees.
• Consensus upgrades and Layer 2 systems are presented as approaches to scaling activity.
• Layer 1 networks support applications such as decentralized finance, NFTs, and supply chain tracking.
• The document does not explain CAMP or FDV despite naming them in its title.
