The U.S. government has taken a notable step toward putting public economic data onchain. On Aug. 28, the Department of Commerce said it had published second-quarter 2025 GDP data to blockchain networks, describing the move as the first time a federal agency has released economic statistical data in this way. The initiative began with the July 2025 release, which showed 3.3% annualized GDP growth based on revised estimates from the Bureau of Economic Analysis.
Official document hash recorded on nine networks
According to the announcement, the department embedded a SHA256 hash of the official GDP release document into transactions or smart contracts on Bitcoin, Ethereum, Solana, Tron, Stellar, Avalanche, Arbitrum One, Polygon PoS, and Optimism. Where each network allowed, the onchain record also included the topline GDP growth figure. The goal was to make the release easier to verify and to provide a tamper-evident method for confirming the integrity of the government document.
Chainlink, Pyth, and major exchanges supported distribution
Chainlink and Pyth helped disseminate the data further, while Coinbase, Gemini, and Kraken provided infrastructure support. The department said the smart contracts were compiled with Solidity v0.8.30 for Ethereum’s Prague fork and v0.8.24 on other networks. Coinbase said on X that onchain data can improve transparency and accessibility, highlighting the broader utility of blockchain in public information systems.
Program may expand to more datasets over time
The Commerce Department said the initiative does not constitute an endorsement of any particular blockchain or related service. Officials added that the program is expected to expand gradually to include more datasets, protocols, and distribution partners. If carried forward, the model could strengthen blockchain’s role in government publishing, public verification, and long-term data preservation.
