US begins publishing economic data on public blockchains
A pilot programme released economic data on nine blockchains, with oracles Chainlink and Pyth making it instantly available to hundreds of applications.
The US Department of Commerce has begun a pilot to publish official economic data on public blockchains to boost transparency and integrity. The first release included GDP figures on nine networks, among them Bitcoin, Ethereum, Solana, and Polygon.
For the July 2025 update, the department issued a cryptographic proof confirming 3.3% annualised GDP growth. In some cases, the topline figure itself was also shared.
Major exchanges such as Coinbase, Gemini, and Kraken supported the rollout, while oracle providers Chainlink and Pyth made the data instantly available across hundreds of applications.
Commerce Secretary Howard Lutnick called the move practical and symbolic, highlighting the Trump administration’s aim to position America as a blockchain leader. He emphasised that putting government data on-chain ensures universal access and creates new opportunities for financial markets.
The pilot may expand to more chains, oracles, and market participants. Officials say future datasets may include inflation and other key metrics, potentially changing how public statistics are shared and used in decentralised finance.
