Sidechains, Spacechains, and Reorg Security | L2L Spaces | 2023-04-13

Super Testnet joins Henry for a Drivechain discussion centered on how sidechains differ from spacechains and how each handles reorg security. Super Testnet explains that spacechains work today but poorly, while Drivechain is still under development and relies on blind merge mining. The conversation turns to whether a Drivechain inherits Bitcoin's un-reorgability, with moonsettler correcting the model: low sidechain activity lowers the cost of reorging it, even though mainchain anchoring limits the number of alternate histories. They also debate one-way pegs and spacechain valuation, including the idea that burned coins can trade at a persistent discount, then compare that dynamic with GBTC's premium and discount. The episode closes with arguments that Drivechain can expand Bitcoin's innovation surface, plus moonsettler's remarks on Chaumian eCash and the ongoing need for chains and data availability.
