Can Bitcoin Really Do DeFi? A New Protocol Aims to Find Out

Summary

A new protocol, OP_NET, is launching to enable decentralized finance (DeFi) functionality directly on Bitcoin’s base layer, allowing trading, token issuance, and other applications to be handled through standard Bitcoin transactions. Unlike typical Bitcoin DeFi solutions that depend on sidechains, bridges, or tokenized (wrapped) assets, OP_NET aims to keep Bitcoin’s liquidity on its own chain. The protocol embeds smart contract interactions within ordinary Bitcoin transactions using native Bitcoin scripting. When users interact with a smart contract, they send contract call data in a Bitcoin transaction, which is then processed by a network of nodes running a virtual machine environment for contract logic execution. These nodes compare states to maintain consensus, ensuring all activity settles directly on Bitcoin. Drawing inspiration from experiments like Bitcoin Ordinals, OP_NET is said to be the first protocol to use an on-chain consensus mechanism among indexers without a separate gas token; all fees are paid in Bitcoin. The founders argue this approach expands Bitcoin’s utility, unlocking DeFi while preserving network security and decentralization.
