ARK, Lightning Fees, and Bitcoin Sidechain Scaling | L2L Spaces | 2023-06-05

Henry welcomes moonsettler for a technical discussion of ARK and Bitcoin scaling. moonsettler explains ARK's virtual UTXOs, the ARK service provider's liquidity constraints, four-week expiries, and unilateral exit. He argues that small VTXOs become economically unenforceable on-chain in a high-fee environment, while sidechains could provide cheaper block space when users need to exit. Paul Sztorc joins to discuss David Harding's ARK liquidity analysis and the tradeoffs around user turnover and capital costs. Hampus then joins the conversation about Lightning: high fees can trigger force closures when nodes disagree over fee rates, and mempool uncertainty, out-of-band fees, and RBF make the problem worse. The group discusses whether ARK can work without a soft fork, how covenants and CTV/APO would simplify it, and how Chomium eCash and long-lived ARK notes could support offline payments. The episode closes with the Drivechain case for preserving Bitcoin's 21 million limit while expanding sidechain software capability.
