Bitcoin L2 Labs, the core development team behind Stacks, has announced the successful mainnet launch of a 1:1 Bitcoin-backed programmable asset, sBTC. This marks a major step toward building an on-chain Bitcoin economy and follows October’s Nakamoto Upgrade, which brought faster transactions and 100% Bitcoin finality to the Stacks network.

For the broader Bitcoin community, this is more than just a milestone; it signals a new era of programmable Bitcoin. The world’s most secure blockchain can now actively participate in decentralized finance (DeFi).
