Layer 2 (L2)

Definition

Layer 2 refers to protocols built on top of Layer 1 blockchains to improve scalability, speed, or functionality. L2 solutions process transactions off the main chain while inheriting L1 security. Post-quantum L2s must consider both their own cryptography and L1's quantum resistance.

Technical Explanation

L2 types: rollups (batch transactions, post proofs to L1), state channels (off-chain transactions, on-chain settlement), sidechains (separate chains with bridges), and plasma (hierarchical chains). Each trades decentralization for throughput.

Quantum considerations: L2s using signatures for fraud proofs or validity proofs need quantum-resistant algorithms. An L2 on a quantum-vulnerable L1 inherits that vulnerability. Best: quantum-resistant L1 with quantum-resistant L2 protocols.

SynX Relevance

SynX's quantum-resistant L1 provides a secure foundation for future L2 solutions. Any scaling solutions built on SynX inherit SPHINCS+ and Kyber-768 security guarantees. L2 protocols can focus on scaling without worrying about base-layer quantum vulnerability.

Frequently Asked Questions

Does SynX have L2 solutions?: L2 development follows L1 maturity. SynX's architecture supports future L2 implementations.
Why not just improve L1 throughput?: L2 allows scaling without sacrificing L1 decentralization or security. They're complementary.
Are L2s less secure than L1?: Well-designed L2s inherit L1 security through cryptographic proofs. Security depends on design.
