The U.S. Department of Commerce announced on Aug. 28 that it has published the second quarter 2025 gross domestic product (GDP) data to the blockchain—marking a first for a federal agency. The initiative began with the July 2025 data, which showed 3.3% annualized growth, according to revised estimates from the U.S. Bureau of Economic Analysis (BEA). Officials framed the move as a milestone in government use of blockchain technology. The Department of Commerce stated:

This is the first time a federal agency has published economic statistical data like this on the blockchain, and the latest way the Department is utilizing innovative technology to protect federal data and promote public use.

The Department embedded a SHA256 hash of the official GDP release document into transactions and smart contracts across nine blockchains— Bitcoin, Ethereum, Solana, Tron, Stellar, Avalanche, Arbitrum One, Polygon PoS, and Optimism. “The Department published this hash to nine blockchains, either as a memo or as data embedded in a smart contract, along with the topline figure, as each chain permitted,” the announcement explains. The measure aimed to verify the document’s integrity, and where allowed, included the topline GDP growth figure.

Oracles Chainlink and Pyth participated in disseminating the data further, while Coinbase, Gemini, and Kraken provided infrastructure support. Smart contracts were compiled using Solidity v0.8.30 for Ethereum’s Prague fork and v0.8.24 elsewhere. Coinbase emphasized the transparency benefits, posting on social media platform X: “We’re proud to be a crypto infrastructure partner of the Department of Commerce on this project. Onchain data = higher transparency + better accessibility.”

Commerce Secretary Howard Lutnick, referencing the broader political narrative, stated: “It’s only fitting that the Commerce Department and President Donald Trump, the Crypto-President, publicly release economic statistical data on the blockchain.” He added:

We are making America’s economic truth immutable and globally accessible like never before, cementing our role as the blockchain capital of the world. And everybody has to admit that 3.3% GDP growth is impressive.

The Department clarified that it does not endorse any particular blockchain or associated service and intends to broaden the program to include more datasets, protocols, and distribution partners over time.
