Here we report on the progress of the leading builders in the zkBitcoin ecosystem, documenting recent significant releases, technical breakthroughs and general updates. Featuring: @AlpenLabs, @babylonlabs_io, @BTC_OS, @citrea_xyz, @FairGateLabs, @fractal_bitcoin, @GOATRollup, @Starknet/@StarkWareLtd, & @TheTNetwork. 🔹 Visit for more reports from across the industry 🔹

Alpen Labs @AlpenLabs has partnered with @StarknetFndn to develop a shared 'Glock verifier' on @Bitcoin, supported by a grant from @Starknet: The project aims to build open, interoperable financial infrastructure that enhances connectivity between Bitcoin-based systems. Through the introduction of @Strata_BTC, a coordination layer linking Alpen and Starknet, users will gain more control over their assets while reducing reliance on intermediaries. 🔸Media 🔸 @simanta_gautam, CEO of Alpen Labs featured in a recent episode of @HouseofZK's ZK Industry Leaders series, explaining how his AI roots led him to Bitcoin: Simanta outlined Alpen’s trust-minimized BTC bridge and modular rollup, using “Glock” garbled-circuit verification to shrink rounds and on-chain data. G He also highlighted his goals for Alpen including privacy, interoperability, great UX for Bitcoin finance, and a Bitcoin-backed dollar. 🔹 Visit for more reports from across the industry 🔹

Citrea 🔸 Publications 🔸 @citrea_xyz published a post explaining that @Bitcoin applications, or ₿apps, can enhance the Bitcoin network by adding liquidity, demand, and value without altering its consensus rules: The project noted that limited Bitcoin app support pushes liquidity and developers to other chains. Citrea says ₿apps, enabled by ZK tech and BitVM, secure Bitcoin’s long-term relevance. 🔸 Integrations 🔸 Citrea has announced that @Alchemy support is now available for ₿app developers on its platform: The integration provides access to Alchemy’s enterprise-grade infrastructure, real-time WebSocket capabilities, and enhanced performance. Developers can use both @ethereum-compatible and Citrea-specific RPC endpoints to build scalable, high-speed applications with improved reliability and data streaming features for blockchain development. 🔹 Visit for more reports from across the industry 🔹

Fairgate @FairGateLabs shared an article explaining how BATTLE for @Bitcoin introduces a dispute resolution layer enabling optimistic bridging on Bitcoin with minimal capital requirements: The protocol adapts the BATTLE tournament framework using BitVM-style components and garbled circuits to resolve disputes efficiently. With its Tournament Chain mechanism and two-phase validation process, BATTLE supports scalable, DoS-resistant bridges and allows large, decentralized participation without altering Bitcoin’s core architecture. 🔹 Visit for more reports from across the industry 🔹

GOAT Network 🔸 Roadmap 🔸 @GOATRollup shared its roadmap for Q4, focusing on advancing @Bitcoin L2 infrastructure and further expanding its ever-growing ecosystem: Key Milestones (past and future) include: • Launch of BitVM2 Beta-Mainnet, plus new releases including Safebox and the @dogecoin Bridge for cross-chain liquidity. • Establishing a development fund, supporting BTCFi projects, and hosting trading competitions. • Reward programs and initiatives to empower long-term contributors. • Activating idle Bitcoin liquidity and collaborating with institutions to deliver sustainable BTC yield. 🔸 Media 🔸 Redouane Elkamhi, Chief Economist at GOAT Network, joined @alicelingl on an episode of @HouseofZK's ZK Industry Leaders series: The University of Toronto Professor explained how his background in electrical engineering and finance led him to Bitcoin in 2013-14, describing it as an economic model built on cryptography. He outlined GOAT Network’s Bitcoin L2 - decentralized operators, a PoS layer atop PoW, L1 commitments, and multicoin staking to earn BTC yield while supporting miners. Other episodes in the series featured @robin_linus, @EliBenSasson, and @simanta_gautam. 🔸 Events 🔸 @sophianeverfold, COO of GOAT Network, took part in the On-Chain Summit hosted by @071_labs in Seoul during @kbwofficial: She discussed the challenges of extending Bitcoin’s functionality without compromising its security, emphasizing that Bitcoin DeFi requires dedicated verifier networks aligned with its trust model - further noting that GOAT Network is developing such decentralized infrastructure secured by Bitcoin. 🔹 Visit for more reports from across the industry 🔹
