Layer 1 (L1)

Definition

Layer 1 refers to the base blockchain network—the main chain handling consensus, security, and transaction finality. L1 defines the fundamental protocol rules. Post-quantum Layer 1 blockchains implement quantum-resistant cryptography at the base protocol level.

Technical Explanation

Layer 1 responsibilities: consensus mechanism, transaction validation, block production, network security, and native token. Examples include Bitcoin, Ethereum, Solana. All higher layers (L2, L3) inherit L1's security assumptions.

Quantum resistance at L1: critical because all layers depend on L1 security. If L1 signatures are quantum-vulnerable, the entire stack is at risk. Post-quantum L1 implementations secure the foundation for the entire ecosystem.

SynX Relevance

SynX is a Layer 1 blockchain with native quantum resistance. Kyber-768 and SPHINCS+ are built into the base protocol—not added later. This ensures all transactions, consensus, and any future L2 solutions inherit quantum-resistant security from the foundation.

Frequently Asked Questions

Why is L1 quantum resistance important?: Higher layers inherit L1 security. Quantum-resistant L1 protects the entire ecosystem.
Can L2 solutions add quantum resistance later?: L2s can add features, but they still depend on L1 security. Better to have quantum-resistant L1.
Is SynX the only quantum-resistant L1?: Few L1s launched with native post-quantum cryptography. SynX prioritized this from the start.
