Layer 2
Layer 2● Common
Protocols built on top of Bitcoin's base layer to enable faster, cheaper, or more private transactions while inheriting Bitcoin's security. The Lightning Network is the primary Layer 2. Others: Liquid (federated sidechain), RGB, Ark.
Technical Notes
Base layer (L1): settlement, security, finality. L2: off-chain scaling, frequent transactions. Lightning: payment channels, HTLCs. Liquid: federated peg, confidential transactions. Trade-offs: different trust/security models than L1.
