Bitlayer: An Innovative Layer 2 Solution for the Bitcoin Ecosystem Bitlayer is a Layer 2 protocol based on the Bitcoin network, designed to enhance the scalability and functionality of Bitcoin while preserving its core security and decentralization features. As the first Layer 2 solution based on BitVM (Bitcoin Virtual Machine), Bitlayer injects new vitality into the Bitcoin ecosystem by introducing Turing-complete smart contract support, cross-chain asset transfers, and efficient transaction processing.
BitVM achieves efficient transaction processing through optimistic Rollup technology, requiring on-chain verification only in case of disputes, significantly reducing the burden on the main chain. LVM separates smart contract execution from zero-knowledge proof (ZKP) verification, supporting complex computations while ensuring privacy and efficiency. Additionally, Bitlayer's BitVM bridging technology realizes trust-minimized asset transfers between BTC and Layer 2 through optimistic discrete log contracts (OP-DLC), with security comparable to the Bitcoin main chain. Its 3-second block confirmation time and low transaction fees (approximately $0.4) significantly enhance user experience.
Bitlayer's native token $BTR (total supply of 2.1 billion) is used for governance, staking, and ecological incentives, with 80% released through liquidity pools, 15% for incubating projects, and 5% for governance. Its EVM compatibility allows Ethereum developers to seamlessly migrate applications, providing infrastructure support for BTCFi (Bitcoin Finance) while leveraging Bitcoin's security. In 2025, Bitlayer plans to launch Mainnet V2, further optimizing the Rollup architecture and BitVM bridge, expanding YBTC cross-chain application scenarios.
