Liquid Network, Bitcoin's confidential sidechain, is seeing real adoption through Brazilian stablecoin transactions and prediction markets, not just speculative hype.
Non-custodial wallets like Sideswap use atomic swaps and open order books to create transparent, competitive markets for assets like Tether and LBTC.
The slow adoption stems from Bitcoin's single-asset design and the technical hurdle of self custody, but practical use in payments is driving organic growth.
FIPS is a new networking protocol that uses Nostr public keys as identities, aiming to let users connect peer-to-peer without traditional ISPs or DNS servers.
The system decouples physical transport (WiFi, Bluetooth, Ethernet) from routing, allowing resilient local meshes that can survive internet shutdowns.
Its long-term ambition is to enable global routing without central authorities, though that capability is still theoretical.
