What is Bitlayer?
Bitlayer is a Layer-2 solution for Bitcoin, introducing smart contract support and enhancing scalability without compromising the security of the Bitcoin network. It is based on BitVM technology and Zero-Knowledge (ZK) proofs.
It stands out through Layered Virtual Machine (LVM) — an architecture that separates the execution part of smart contracts from the proof generation part, ensuring efficiency and security.

Key features and capabilities
1. Scalability and low fees
Bitlayer processes off-chain transactions and then groups them into rollups, reducing costs and increasing speed.
The use of ZK-proofs ensures instant transaction confirmation (instant finality), reducing wait and verification times.
2. Smart contracts on Bitcoin
With EVM (Ethereum Virtual Machine) compatibility, developers can port Solidity-based applications with minimal changes.
3. Trustless bridge for BTC
BitVM Bridge and OP-DLC mechanisms enable secure, decentralized asset transfer between Bitcoin and L2, eliminating the need for trusted intermediaries.
4. Collaboration with other chains
Bitlayer has established strategic partnerships with Base, Arbitrum, Starknet, Sonic, and Plume Network, allowing for seamless liquidity and asset transfer between these ecosystems and Bitcoin.

Current development and roadmap
Mainnet V1 — launched in 2024, based on a PoS model and the BitVM prototype.
Mainnet V2 — OPVM (fraud proof) and the so-called finality bridge were introduced in Q4 2024.
Mainnet V3 — planned for Q2 2025, with advanced proof-of-validity and Realtime EVM for even faster transactions.

What else is worth knowing?
The project is being developed by a team supported by renowned investors: Polychain Capital, Framework Ventures, Franklin Templeton, and others.
Several funding rounds have already taken place — from seed (March 2024) to strategic and public IDOs in collaboration with CoinList and Binance Wallet. The Token Generation Event (TGE) is expected in Q3 2025.

Why does Bitlayer matter?
Bitlayer fits into the growing trend of building DeFi on Bitcoin — it offers programmability, low fees, fast transactions, and interoperability while maintaining the highest level of security.
This is a key step in the development of Bitcoin as a foundation for dApps, DeFi, and Web3.
