Non-Lightning Layer 2 Panel
summary
Panel argues Lightning is not perfectly trustless—miners can censor or reorg and users must be vigilant—so other Layer 2s matter. bip300 compresses sidechain withdrawals into one hash with a proposed 3–6 month delay and merge‑mining to enable many sidechains; Drivechain variants replicate altcoins as sidechains. Liquid runs confidential transactions and an AMM but reports low uptake (order‑of‑hundreds daily volume on some services). Federated ecash prototypes prioritize privacy and offer Lightning gateways; several systems exist on testnets but wider adoption remains unproven.
