The Stacks blockchain ecosystem has recently increased the supply cap of sBTC, a Bitcoin-pegged token, to 5,000 sBTC, equivalent to approximately $550 million in Bitcoin. This cap-3 raise, completed within 2.5 hours, added 2,000 sBTC to the ecosystem, which previously held around 3,000 sBTC valued at $330 million. The expansion positions Stacks as the second-largest Bitcoin Layer 2 solution by BTC supply, surpassing the Lightning Network. Stacks' latest roadmap includes improvements such as faster block times, enhanced stacking, better custody options, dual stacking, and progress toward trustless sBTC. The ecosystem is also focusing on DeFi growth, increasing total value locked (TVL), centralized exchange listings, wallet integrations, and stablecoin development. Zest Protocol, a key platform within Stacks, offers users approximately 4.5% annual percentage yield (APY) on sBTC and has integrated with the Leather web app to facilitate easier access to Bitcoin yield. Other projects like Bitflow Finance and Babylon Genesis are contributing to the growing Bitcoin DeFi (BTCFi) space, with Babylon Genesis currently staking nearly 49,850 BTC worth about $5.52 billion. The BTCFi movement emphasizes non-custodial staking and trustless finance, allowing users to earn yield on Bitcoin without wrapping or bridging assets. Industry discussions continue on Bitcoin's role as a base layer for trustless finance, smart contract capabilities, and the real-world impact of Bitcoin-backed stablecoins.
