Breaking Boundaries: The Impact of Bitcoin Layer 2
summary
Stacks launches a programmable Bitcoin L2 that settles to Bitcoin L1 and aims for 100% Bitcoin mining hash power security, paying actual BTC rewards to consensus participants. Contrast with Lightning, which supports only payments; Stacks adds smart contracts via Clarity, a decentralized signer set handling BTC withdrawals with about $300 million locked today. Upcoming fast blocks give ~5s L2 confirmations while batching settlement to slower Bitcoin blocks, reducing fees and unlocking on‑chain NFTs, stablecoins and lending on BTC.
