Scaling Bitcoin to 2050
summary
Debates concrete scaling paths: channel-based Lightning with penalty/justice transactions and channel factories versus rollups using zero-knowledge proofs that post a tiny validity proof to Bitcoin, claiming 30–100x compression of transaction data; notes a real-world economic failure when a service provider paused Lightning operations for one day due to costs; flags the 21 million BTC supply as a liquidity constraint; explores composability via atomic/submarine swaps and hybrid channel-rollup designs.
