⚡ Layer 2 & Scaling: Bitcoin Layer 2

Zest Bets’ announcement that Bitcoin can back loans without leaving its own chain signals a shift toward on‑chain credit mechanisms, reducing reliance on off‑chain rollups and potentially lowering counterparty risk. If implemented, this could accelerate institutional interest in Bitcoin‑backed assets, tightening liquidity on layer‑1 and encouraging the development of smart‑contract‑like functionality directly on Bitcoin. The move also dovetails with the broader trend of integrating DeFi primitives into Bitcoin, which may prompt regulators to revisit custody and securities frameworks, especially in jurisdictions tightening crypto oversight. Meanwhile, the Bitcoin Foundation’s curated list of layer‑2 projects for 2026 highlights a growing ecosystem of sidechains, payment channels, and state‑channel solutions. Projects such as Lightning Network, Liquid, and emerging rollup‑style protocols are positioned to address throughput and cost issues, potentially drawing volume away from Bitcoin’s base layer.
