The test excluded Cardano and XRP while Chainlink and Pyth now carry US government GDP data. The US Department of Commerce has begun publishing official economic statistics directly on public blockchains, describing this as a new approach to transparency and data security.
The pilot program launched on August 28 includes nine networks, including Bitcoin, Ethereum, Solana, TRON, Stellar, Avalanche, Arbitrum One, Polygon PoS, and Optimism.
“The Department published an official hash of its quarterly GDP data release for 2025—and, in some cases, the topline GDP number.”
The announcement confirmed,
Notably, other leading blockchain networks like XRP Ledger and Cardano did not participate in the initial rollout.
The authorities pointed out that major US exchanges, including Coinbase, Gemini, and Kraken, assisted in making the datasets available.
The government added that future releases could be expanded to additional chains, oracles, and market participants as the program matures.
US GDP Growth Confirmed at 3.3%
For the first release, a cryptographic proof of its July 2025 gross domestic product (GDP) update was issued by the department, which showed annualized growth of 3.3%. In some cases, the topline GDP number itself was also shared by the department.
The US government said the effort is designed to make federal data immutable and universally accessible, while testing blockchain’s ability to serve as a permanent publishing platform.
Commerce Secretary Howard Lutnick framed the initiative as both symbolic and practical. He stated:
“It’s only fitting that the Commerce Department and President Donald Trump, the Crypto-President, publicly release economic statistical data on the blockchain. We are making America’s economic truth immutable and globally accessible like never before, cementing our role as the blockchain capital of the world.”
Notably, this comes less than two days after Lutnick revealed that the Donald Trump-led government planned to issue economic data on public blockchains.
Oracle Providers Distribute US Government Data on-Chain
Meanwhile, the data is being simultaneously distributed through Chainlink and Pyth, two major oracle providers.
Chainlink confirmed that several indicators compiled by the Bureau of Economic Analysis—including GDP, the PCE Price Index, and real final sales to private domestic purchasers—are now available on-chain for the first time.
According to the firm, these metrics will be refreshed monthly or quarterly. It was added:
“Bringing US government data onchain unlocks innovative use cases for blockchain markets, such as automated trading strategies, increased composability of tokenized assets, the issuance of new types of digital assets, real-time prediction markets for crowdsourced intelligence, transparent dashboards powered by immutable data, and DeFi protocol risk management based on macroeconomic factors.”
Solana-based Pyth added that “the data [would become] instantly accessible to 600+ connected applications across 100+ blockchains.”
