#美国宏观经济数据上链 The U.S. Department of Commerce announced in August 2025 that it will put macroeconomic data such as GDP on the blockchain, involving nine major blockchains including Bitcoin, Ethereum, and Solana, marking the first large-scale adoption of blockchain technology by the government to release economic data. Secretary of Commerce Howard Lutnick promoted this initiative aimed at enhancing data transparency and immutability, utilizing oracles like Chainlink and Pyth Network to ensure data security on the blockchain. The first batch of data includes GDP (3.3% growth in Q2 2025), PCE price index, among others, with potential expansion to more indicators in the future. This move not only enhances data credibility but also provides real-time data support for DeFi, prediction markets, and promotes financial innovation. However, the blockchain only ensures data immutability after publication, and the accuracy of the initial data still relies on the collection process, which poses potential risks. The Trump administration's pro-crypto policies and the political influence of the industry (over $133 million in donations for the 2024 election) have driven this trend, reflecting the transformation of blockchain from cryptocurrency to public data infrastructure, but the technical details and long-term effects need further observation.
