U.S. government records Gross Domestic Product data on blockchain technology

In a groundbreaking move, the U.S. Department of Commerce has published the GDP data for the second quarter of 2025 on the blockchain. This marks the first time a federal agency has taken such a step, demonstrating the wide utility of blockchain technology and a proof of concept for all of government.

The contract, compiled with Solidity compiler versions v0.8.30 on Ethereum mainnet and v0.8.24 on other chains, was published on multiple blockchains, including Bitcoin, Ethereum, Solana, TRON, Stellar, Avalanche, Arbitrum One, Polygon PoS, and Optimism.

The contract contains three variables: , , and . The variable stores the SHA256 Hash of the GDP Q2 2025 PDF file from the Bureau of Economic Analysis. The resulting hash, , was generated from this process.

The variable stores the GDP data for Q2 2025 as increments of tenths. The Department of Commerce aims to provide transparency and accessibility by publishing this data on the blockchain.

The contract was deployed with a constructor that takes two arguments: the hash of the GDP PDF and the GDP data for Q2 2025. The optimizer was disabled, and the EVM version was set to Prague on mainnet and Cancun elsewhere during the compilation.

The data was also disseminated through coordination with the oracles, Pyth and Chainlink. The co-founder of Chainlink, Sergey Nazarov, has been mentioned in connection with this release. Exchanges, such as Coinbase, Gemini, and Kraken, helped facilitate the Department's publishing.

It's important to note that the Department of Commerce has published this data for informational purposes only and does not endorse any specific blockchain, service, or associated activities. The Bureau of Economic Analysis data can be accessed through the agency's Application Programming Interface available at https://apps.bea.gov/API/signup/.

The Department began posting real GDP data on the blockchain starting from July 2025. This move aligns with the Trump Administration's historic efforts to make the United States the blockchain capital of the world. The Department hopes to build on these efforts and continue to leverage blockchain technology for the benefit of the American people.
