What Is Bitlayer?
Bitlayer is a Bitcoin-native Layer 2 (L2) solution that brings Turing-complete smart contract functionality and enhanced scalability to the Bitcoin ecosystem while preserving its core security. It achieves this through the innovative BitVM paradigm—an optimistic rollup-style mechanism designed to execute arbitrary computation, with state transitions verified on Bitcoin’s base layer.
Key Features:
BitVM Bridge: A trust-minimized, challenge-based protocol serving as a gateway for transferring BTC into Bitlayer.
Rollup Architecture with Recursive Settlement: State transitions are bundled off-chain and periodically anchored to Bitcoin using BitVM, ensuring that the L2 chain inherits security directly from the Bitcoin blockchain.
Turing-Complete, EVM-Compatible Execution Engine: Developers can deploy complex smart contracts—including Ethereum-based ones—with sub-second soft finality and Bitcoin-level security.
Dual Finality Model: Fast soft finality through PoS and secure hard finality when state is settled on Bitcoin, typically within about a week.
Strong Founding Team and Backing: Founded in 2023 by veterans from Polygon, Huobi, and Polkadot, and backed by major investors such as Polychain, Franklin Templeton, and OKX Ventures.
Impressive Adoption Metrics: Over $550 million in total value locked (TVL), 300+ projects launched, 150,000+ daily transactions, and a user base of 700,000+.
Native Ecosystem Token (BTR): The BTR token powers governance, staking, node voting, and protocol operations, with a total supply around 1 billion.
hy Bitlayer Matters
