Second Layers
summary
Panel defines a layer as an external system that settles to Bitcoin in a trustless or deterministic way, arguing Lightning meets that bar while Liquid and Fedimint do not. Lightning scales transaction frequency but not users; Lightning requires online enforcement. Fedimint is a multi-sig federation mint offering private e‑cash, one node can serve tens‑to‑hundreds of thousands of users and a mainnet trial federation is running. Liquid is an 11‑of‑15 federated sidechain with 1‑minute blocks, confidential transactions and a non‑custodial atomic swap orderbook.
