US GDP data is uploaded to nine blockchains for the first time, making it tamper-proof.

The U.S. Department of Commerce has begun publishing official economic statistics directly onto a public blockchain, describing the move as a new initiative to enhance transparency and data security. The pilot program, launched on August 28, covers nine blockchain networks: Bitcoin, Ethereum, Solana, TRON, Stellar, Avalanche, Arbitrum One, Polygon PoS, and Optimism. The announcement clearly stated: "The Ministry of Commerce has released the official hash value of the quarterly GDP data for 2025. In some cases, the total GDP data has also been released simultaneously." It is worth noting that other mainstream blockchain networks such as XRP Ledger and Cardano did not participate in this initial deployment. Officials stated that major US exchanges such as Coinbase, Gemini, and Kraken have helped promote the accessibility of these data sets. The government added that as the project matures, future data releases may be expanded to include more blockchains, oracles, and market participants. In its first data release, the Ministry of Commerce provided cryptographic proof of updated GDP data for July 2025, which showed an annualized growth rate of 3.3% for U.S. GDP. In some cases, the Ministry of Commerce also directly shared the GDP aggregate data itself.

The US government said that the move aims to make federal data "unalterable" and "globally accessible" while testing the ability of blockchain as a permanent publishing platform.

U.S. Commerce Secretary Howard Lutnick defined the move as "both symbolic and practical", saying:

"It is fitting that the Department of Commerce and President Donald Trump, the 'Crypto President', are working together to publish economic statistics on the blockchain. We are making America's economic truth immutable and globally accessible in an unprecedented way, consolidating the United States' position as the 'Blockchain Capital of the World.'"

It is worth noting that less than two days ago, Lutnick revealed that the administration led by Donald Trump plans to publish economic data on a public blockchain.

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

Chainlink confirmed that several indicators compiled by the Bureau of Economic Analysis, including GDP, the Personal Consumption Expenditures Price Index (PCE Price Index), and actual final sales by private domestic buyers, are now accessible on-chain for the first time. ... The company said the metrics will be updated monthly or quarterly, adding: “Bringing U.S. government data to blockchain unlocks numerous innovative use cases for the blockchain market, such as automated trading strategies, increased composability of tokenized assets, new digital asset issuance, real-time prediction markets based on crowdsourced intelligence, transparent dashboards driven by immutable data, and risk management for DeFi protocols based on macroeconomic factors.” Pyth, which is built on Solana, added, “This data will be instantly accessible to over 600 connected applications on over 100 blockchains.”
