Layer 2s: Fairer Bitcoin for the Global South
summary
Shows that Layer 2s cut real costs: onchain spikes hit 600 sats/vbyte (~$40 priority fees) while Liquid runs 1-minute blocks and confidential transactions with fees about ten times lower. Lightning offers near-instant, low-fee routed payments but requires channel balancing, online keys and active liquidity management. Liquid is a federated sidechain with a 11-of-15 pegout custody model, supports USDT and tokenized assets, had one resolvable block-production bug in 2021, and pairs with tools like Aqua, peer-swap and BoltS Exchange for swaps and liquidity.
