Layer 1 vs Layer 2 Blockchains
The base layer secures; the second layer scales. Here is how they fit together.
A Layer 1 (L1) is a base blockchain that provides security and final settlement — Ethereum is the best-known example. A Layer 2 (L2) is a network built on top of an L1 to increase speed and reduce cost, while relying on the L1 for security.
Why Layer 2 exists
Base layers prioritise security and decentralisation, which limits throughput. L2s process transactions off the base chain and post compressed proofs or data back to it — scaling capacity without sacrificing the L1's security guarantees.
Rollups
- ZK rollups post a cryptographic validity proof for each batch.
- Optimistic rollups assume validity and allow a challenge window.
Where Syrax sits
The Syrax chain is a zero-knowledge Layer-2 — high throughput and low cost, with settlement secured by its Layer-1 base. See zero-knowledge proofs for the underlying tech.
