OP_NET is a Bitcoin metaprotocol designed to bring fully expressive smart contract functionality directly to Bitcoin's Layer 1 without requiring Bitcoin Improvement Proposals or changes to the Bitcoin core protocol. It operates by utilizing Tapscript to create a smart contract environment integrated seamlessly with Bitcoin, enabling developers to build decentralized applications on Bitcoin with security guaranteed by Bitcoin's consensus and settlement layer. OP_NET supports WebAssembly compatibility with multiple languages for development and enables Bitcoin-native DeFi applications such as DEXs, lending, and staking. Transactions retain Bitcoin as the gas token and occur fully on-chain, maintaining alignment with Bitcoin's design principles. The protocol's execution layer (consisting of OP_VM and OP_NET nodes) handles smart contract operation while the Bitcoin mainnet serves as the initiation and final confirmation layer. OP_NET charges an execution fee and priority fee in Bitcoin, introducing a unique fee model that includes burning Bitcoin as part of transaction costs.
