#Bitlayer_BitVM Bitlayer BitVM and Bitcoin Anchoring **: The core of Bitlayer is **BitVM (Bitcoin Virtual Machine)**, which allows complex, Turing-complete smart contracts to be executed off-chain, with only **verification and dispute resolution** occurring on the Bitcoin main chain. This is like offloading heavy computational work to be done offline, only submitting the final result and necessary proofs to the Bitcoin network for confirmation, thereby greatly reducing the burden on the main chain.
* **Trustless Bi-directional Bridging**: This is a significant innovation in security for Bitlayer. It combines **OP-DLC (Optimistic Discreet Log Contracts)** and **BitVM Bridge** technologies to achieve **trustless bi-directional transfers** of Bitcoin between Layer 1 and Layer 2. This means that when users transfer assets across chains, they **do not need to entrust their assets to intermediaries or multi-signature alliances**, but instead ensure security through cryptographic contracts and fraud-proof mechanisms, allowing users to always maintain control of their assets. Users can even choose different bridging paths based on varying needs for speed and security.
* **Layered Virtual Machine (LVM)**: The design of LVM **decouples the execution of contracts from the generation of proofs**. This design allows Bitlayer to support multiple virtual machines, such as **EVM (Ethereum Virtual Machine)**, Cairo VM (Starknet), and Move VM (Aptos/Sui), among others. Notably, its **100% EVM compatibility** enables developers on Ethereum to migrate their Solidity-based DApps to Bitlayer at almost no cost, seamlessly accessing Bitcoin's powerful security and liquidity.
