The Bitcoin ecosystem is undergoing an evolution from a pure store of value to a smart contract platform. As Layer2 solutions, BRC-20 inscriptions, and lending protocols are launched intensively, an invisible infrastructure need has emerged—trustworthy data sources.

Why does the Bitcoin ecosystem need oracles so much? Think about it: asset flows between Layer2 and the mainnet—who needs to verify cross-chain status? BRC-20 inscriptions want to enter the DeFi ecosystem to create trading pairs or collateral—where does the price data come from? This is not a trivial issue—data errors or tampering could directly lead to funds loss.

Some projects have already begun to deploy in this area. For example, certain oracle solutions adopt decentralized node network architectures, with native adaptations for Bitcoin mainnet, major Layer2s, and the Lightning Network. Their approach is: ensure data integrity through cryptographic commitments and distributed verification, while optimizing costs to make them affordable for new projects.

Interestingly, these infrastructure projects often issue governance tokens. Holders can vote on how network resources are allocated across ecosystems, and node operators stake tokens to participate in data provision and earn rewards. In plain terms—when demand in the Bitcoin ecosystem grows, the value of the entire oracle network also increases.

The current pressing question is: which will be the first to unleash massive demand for trustworthy data sources—Bitcoin Layer2 DeFi ecosystem, NFT/inscription trading markets, or other sectors?
