The U.S. Department of Commerce has begun publishing official economic statistics directly to public blockchains, calling it a new initiative to enhance transparency and data security.

The pilot program launched on August 28 covers nine blockchain networks, including Bitcoin, Ethereum, Solana, TRON, Stellar, Avalanche, Arbitrum One, Polygon PoS, and Optimism.

The announcement explicitly stated: "The Department of Commerce released the official hash of the Q2 2025 GDP data, and in some scenarios, also simultaneously published the total GDP data."

Notably, other major blockchain networks such as XRP Ledger and Cardano were not included in this initial deployment.

Officials stated that major U.S. exchanges like Coinbase, Gemini, and Kraken have assisted in promoting the accessibility of these datasets.

The government added that as the project matures, future data releases may expand to more blockchains, oracles, and market participants.

In the first data release, the Department of Commerce provided cryptographic proof for the July 2025 GDP update, which showed an annualized growth rate of 3.3% for U.S. GDP. In some scenarios, the Department also directly shared the total GDP data itself.

The U.S. government stated that this move aims to achieve "immutability" and "global accessibility" of federal data while testing blockchain's capability as a permanent publishing platform.

U.S. Secretary of Commerce Howard Lutnick defined the initiative as "both symbolic and practical," stating:

"It is only fitting that the Department of Commerce, alongside President Donald Trump, the 'Crypto President,' is publishing economic statistics on the blockchain. We are making America's economic truth immutable and globally accessible in an unprecedented way, solidifying the U.S. as the 'Blockchain Capital of the World.'"

It is worth noting that less than two days ago, Lutnick revealed that the Trump administration plans to publish economic data to public blockchains.

Meanwhile, the data is being simultaneously distributed through two major oracle providers, Chainlink and Pyth.

Chainlink confirmed that multiple metrics compiled by the Bureau of Economic Analysis, including GDP, the Personal Consumption Expenditures (PCE) Price Index, and Real Final Sales to Domestic Purchasers, are now accessible on-chain for the first time.

The company stated that these metrics will be updated monthly or quarterly, adding:

"Putting U.S. government data on-chain unlocks numerous innovative use cases for blockchain markets, such as automated trading strategies, enhanced composability of tokenized assets, issuance of new digital assets, real-time prediction markets based on crowdsourced intelligence, transparent dashboards powered by immutable data, and risk management for DeFi protocols based on macroeconomic factors."

Solana-based Pyth added, "This data will be instantly accessible to over 600 applications across more than 100 blockchains."
