What is Bitlayer?
Bitlayer is a second layer (Layer-2) for Bitcoin that introduces smart contract support and increases 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 transactions off-chain and then batches them into rollups, reducing costs and increasing speed.
The use of ZK-proofs ensures instant transaction confirmation, reducing waiting and verification time.
2. Smart contracts on Bitcoin
Thanks to compatibility with EVM (Ethereum Virtual Machine), developers can migrate Solidity-based applications without significant changes.
3. Trustless bridge for BTC
BitVM Bridge and OP-DLC mechanisms enable secure, decentralized asset transfers 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, enabling seamless liquidity and asset transfers between these ecosystems and Bitcoin.

Current development and roadmap
Mainnet V1 - launched in 2024, based on the PoS model and BitVM prototype.
Mainnet V2 - in Q4 2024, OPVM (fraud proof) and the so-called finality bridge were introduced.
Mainnet V3 - scheduled for Q2 2025, featuring 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 been conducted - from seed (March 2024) to strategic and public IDOs in collaboration with CoinList and Binance Wallet. The Token Generation Event (TGE) is anticipated in Q3 2025.

Why does Bitlayer matter?
Bitlayer fits into the growing trend of building DeFi based on Bitcoin - offering 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.
