#bitlayer @BitlayerLabs Bitlayer is a Bitcoin-native Layer-2 protocol built upon the BitVM paradigm—a computing framework enabling Turing-complete smart contracts on Bitcoin without requiring protocol changes (no soft or hard forks)  . It functions through an optimistic rollup-like structure, leveraging fraud proofs and ZK validation to settle transactions on Bitcoin’s chain securely  .

2. Roadmap Highlights

Bitlayer’s journey is planned in stages:

• Stage 1 (PoS Foundation – April 2024): Bitlayer started with a Proof-of-Stake (PoS) multisignature architecture, offering full EVM compatibility and cross-chain Stage 2 (BitVM Rollup – Early 2025): The transition to a rollup model anchored on Bitcoin. This includes launching a trust-minimized BTC bridge, phasing out multisig reliance for enhanced decentralization  .

• Stage 3 (Supercharged Rollup – Target Q4 2025): Aiming for high performance—20,000 TPS, 3-second confirmations, and enterprise-ready scalability .

3. Major Partnerships & Launches

• BitVM Bridge Mainnet Beta (July 2025): Bitlayer unveiled its first trust-minimized bridge to move Bitcoin into programmable ecosystems as YBTC tokens, pegged 1:1 to BTC and usable across Bitlayer Rollu Mining Pool Backing: Major Bitcoin mining pools—Antpool, F2Pool, SpiderPool, controlling around 31.5% of hash rate—have joined in securing the BitVM architecture and enabling real-time NST inclusion   .

• Ecosystem Integration: Bitlayer is building bridges and interoperability with Base, Arbitrum, Starknet, Sonic SVM, Plume Network, and more—bolstering its DeFi credibility and multi-chain connectivity   .
