The U.S. government used public blockchains to distribute GDP data. Commerce Department officials stated that this move will create a new way to release economic data, not replace existing methods. The department announced on nine blockchains—Bitcoin, Ethereum, Solana, TRON, Stellar, Avalanche, Arbitrum One, Polygon PoS, and Optimism—the ‘official hash of its quarterly GDP data release for 2025,’ and in some cases, the topline GDP figure, in a press release.

This endorsement of blockchain technology, originating from cryptocurrency but now used for trading stocks, money-market funds, and more, reflects the Commerce Department’s decision to leverage it for some of its most significant and market-sensitive economic data.

This development comes weeks after Trump dismissed the head of the Bureau of Labor Statistics following an agency report that showed slower job growth in recent months than previously estimated. The president suggested, without proof, that the figures were manipulated for political reasons. According to Commerce Department officials, the blockchain project is unrelated to the BLS’s dismissal.

Commerce Secretary Howard Lutnick also hinted that he aimed to change how GDP is reported to reduce government spending. The Bureau of Economic Analysis, part of the Commerce Department, is responsible for releasing these figures.
